Desizing is the process of removing the size material from warp yarns after a textile fabric is woven.[1]

Sizing agents

[edit]

Sizing agents are selected on the basis of type of fabric, environmental friendliness, ease of removal, cost considerations, effluent treatment, etc.

Natural sizing agents

[edit]

Natural sizing agents are based on natural substances and their derivatives:

Synthetic sizing agents

[edit]

Desizing processes

[edit]

Desizing, irrespective of what the desizing agent is, involves impregnation of the fabric with the desizing agent, allowing the desizing agent to degrade or solubilise the size material, and finally to wash out the degradation products. The major desizing processes are:

  • Enzymatic desizing of starches on cotton fabrics
  • Oxidative desizing
  • Acid desizing
  • Removal of water-soluble sizes
  • Fermentative desizing

Enzymatic desizing

[edit]

Enzymatic desizing is the classical desizing process of degrading starch size on cotton fabrics using enzymes. Enzymes are complex organic, soluble bio-catalysts, formed by living organisms, that catalyze chemical reaction in biological processes. Enzymes are quite specific in their action on a particular substance. A small quantity of enzyme is able to decompose a large quantity of the substance it acts upon. Enzymes are usually named by the kind of substance degraded in the reaction it catalyzes.

Amylases are the enzymes that hydrolyses and reduce the molecular weight of amylose and amylopectin molecules in starch, rendering it water-soluble enough to be washed off the fabric.

Effective enzymatic desizing require strict control of pH, temperature, water hardness, electrolyte addition and choice of surfactant.

Oxidative desizing

[edit]

In oxidative desizing, the risk of damage to the cellulose fiber is very high, and its use for desizing is increasingly rare. Oxidative desizing uses potassium or sodium persulfate or sodium bromite as an oxidizing agent.

Acid desizing

[edit]

Cold solutions of dilute sulphuric or hydrochloric acids are used to hydrolyze the starch, however, this has the disadvantage of also affecting the cellulose fiber in cotton fabrics.

Removal of water-soluble sizes

[edit]

Fabrics containing water-soluble sizes can be desized by washing using hot water, perhaps containing wetting agents (surfactants) and a mild alkali. The water replaces the size on the outer surface of the fiber, and absorbs within the fiber to remove any fabric residue.

Fermentative desizing

[edit]

Fermentative desizing is defined as a fermentation process and involves the Generally Regarded as Safe (GRAS) microorganisms that have a high potential to produce enzymes; it is carried out via impregnation/padding methods, which provide online monitoring and accurate control. The method allows an economical process with low resource consumption and emission compared to the enzymatic method, it is considerably cheaper.[2]

from Grokipedia
Desizing is the initial wet processing step in , involving the removal of agents—such as , (PVA), or (CMC)—applied to warp yarns prior to to protect them from abrasion and breakage during the loom process, thereby preparing the fabric for subsequent treatments including scouring, bleaching, , and finishing. This process is essential for enhancing fabric absorbency, improving the uniformity of dye uptake, and preventing defects in or finishing by eliminating the stiff, water-repellent layer that could otherwise interfere with chemical penetration. agents, typically applied as a paste to increase yarn strength and , must be efficiently removed to achieve optimal fabric handle and performance in end-use applications. Desizing methods are categorized into hydrolytic and oxidative types, with enzymatic desizing—utilizing enzymes to hydrolyze into soluble dextrins and sugars—gaining prominence for its eco-friendly profile, operating under milder conditions (e.g., 55–60°C, pH 5–7) and reducing compared to harsher acid or alkaline . Oxidative approaches, such as those using sodium bromite or , degrade through chemical oxidation but may cause fabric strength loss if not controlled. The choice of method depends on the type, fabric composition, and environmental considerations, with measured by standards like the TEGEWA scale for residual removal.

Introduction

Definition and Purpose

Desizing is the initial wet processing step in , involving the removal of protective compounds applied to warp yarns prior to to enhance their strength, reduce breakage, and minimize abrasion during the high-tension process. These agents form a temporary that protects the delicate warp yarns from mechanical stresses in modern high-speed looms. The primary purpose of desizing is to restore the fabric's natural absorbency, permeability, and chemical reactivity, enabling effective subsequent treatments such as scouring, bleaching, , and finishing. Without desizing, the hydrophobic layer impairs wettability, leading to uneven uptake and poor penetration of chemicals, which compromises fabric and . This step ensures the fabric achieves uniform hydrophilicity and prepares it for optimal interaction with dyes and finishes in the production pipeline. In contemporary , the degree of typically ranges from 8% to 15% of the warp yarn's weight, depending on fabric type and conditions, such as higher add-ons for warps to withstand intensive abrasion. Desizing efficiency is evaluated through measurements to confirm substantial removal of the applied size and readiness for further . agents include natural options like starches and synthetic polymers, selected based on yarn composition and end-use requirements.

Role in Textile Processing

Desizing serves as the initial step in the wet processing sequence of , occurring immediately after and often following singeing to remove protruding fibers. This placement is crucial because the sizing agents applied to warp yarns during —such as for or (PVA) for blends—must be eliminated to prepare the fabric for subsequent operations like scouring (removal of natural impurities), bleaching (for whitening), mercerizing (to enhance strength and luster), , and . The process ensures a substrate for downstream treatments by facilitating the even penetration of chemicals and dyes; incomplete desizing can result in defects such as uneven , spotting, or streaky patterns due to residual acting as a barrier, and it may also lead to reduced tensile strength in finishing stages by causing irregular chemical reactions. Desizing requirements vary by fabric type: it is essential for and cotton-blend fabrics, which typically receive heavy starch-based to withstand weaving stresses, whereas pure synthetics like often require minimal or no desizing since they use lighter, water-soluble sizes that dissolve more readily in later aqueous processes. Processing can be adapted to batch methods for smaller lots, where fabric is steeped in desizing baths, or continuous flows like pad-batch systems for higher efficiency in large-scale production, allowing fabric to be padded with desizing and batched for reaction time before washing. Quality control in desizing involves specific tests to verify effectiveness, such as the iodine test, where a drop of iodine solution on the fabric turns blue-black if starch residues remain, indicating incomplete removal, and the drop test (per AATCC-79 standard), which measures absorbency by timing how quickly a water drop penetrates the fabric surface—ideally under 3 seconds for well-desized material. These assessments, often rated on the Tegewa scale for visual starch detection, help prevent downstream issues and ensure fabric readiness.

Sizing Agents

Natural Sizing Agents

Natural sizing agents, derived from plant-based materials, have been integral to processing for centuries, providing a protective to warp yarns during . These agents primarily include starches extracted from sources such as corn, , and , which are modified through processes like gelatinization to form flexible, film-forming layers that enhance yarn strength and reduce breakage. gums, such as derived from guar seeds and (CMC) derived from cellulose, serve as viscosity modifiers and binders, often blended with starches to improve adhesion and flow properties in sizing solutions. has been used in European processing since the to stiffen and protect yarns during . Preparation of these agents begins with extraction from renewable plant sources, followed by cooking to create viscous solutions suitable for application. Starches are typically gelatinized by heating slurries to 80-100°C, allowing the granules to swell and form a paste that can be applied via or slasher machines to achieve add-on levels of approximately 8-12% on warps, optimizing abrasion resistance without excessive . and CMC are processed into powders or solutions, with CMC offering water-solubility through etherification of , enabling easy dispersion at lower temperatures. These biologically derived materials are cost-effective, with native starches priced around $0.20-0.50 per kg, making them accessible for large-scale operations. Key properties of natural sizing agents include biodegradability and strong to hydrophilic s like , contributing to improved efficiency through enhanced tensile strength and reduced hairiness. However, they are susceptible to microbial degradation, leading to in storage, and exhibit variable quality influenced by crop conditions, which can affect and . Their poor in cold water necessitates desizing steps, often addressed enzymatically to avoid . Advantages encompass renewable sourcing and environmental compatibility, though disadvantages like sensitivity to and the need for precise formulation control limit their standalone use in high-speed modern .

Synthetic Sizing Agents

Synthetic sizing agents are man-made polymers engineered to provide protective coatings on warp yarns during , offering superior performance compared to traditional materials in high-speed operations. The primary types include (PVA), polyacrylates, and resins, each tailored for specific types and processing conditions. PVA, a water-soluble film-former, is produced by the of , where the degree of —typically ranging from 88% to 99%—directly influences its and film-forming properties; partially hydrolyzed variants (around 88%) exhibit higher cold-water , while fully hydrolyzed ones (98-99%) require warmer conditions for dissolution but provide stronger, more durable films. These agents are synthesized through polymerization processes: PVA via the alcoholysis of polyvinyl acetate, polyacrylates through emulsion polymerization of acrylic acid derivatives (such as sodium polyacrylate or copolymers), and polyester resins via condensation of glycols and aromatic acids with solubilizing groups like sodium sulfonates. Key properties include high tensile strength (7,000-15,000 psi for PVA films), low friction coefficients to minimize yarn abrasion on modern looms, and resistance to humidity, particularly for polyester resins that maintain integrity in damp environments. Add-on levels typically range from 6-10% of yarn weight, enabling weaving speeds up to 1000 picks per minute on air-jet or rapier looms. Costs for these agents generally fall between $1-2 per kg, making them viable for industrial-scale use. In applications, synthetic sizing agents excel with synthetic fibers such as /cotton blends and multifilament yarns; PVA adheres well to both hydrophilic and hydrophobic fibers, polyacrylates enhance abrasion resistance in and staple yarns, and polyester resins provide optimal lubrication for fine-denier filaments in high-speed . Their advantages include consistent film uniformity for reliable performance across batches and reduced dusting during processing, which improves workplace safety and loom efficiency. However, these agents are non-biodegradable, leading to higher (COD) in effluents and necessitating advanced to mitigate environmental impacts. Water-soluble variants like PVA can often be removed with milder conditions, avoiding harsh chemicals in subsequent desizing steps.

Desizing Processes

Enzymatic Desizing

Enzymatic desizing employs enzymes to selectively hydrolyze starch-based sizing agents through biological , breaking down complex polymers into simpler soluble carbohydrates. Alpha-amylases, the primary enzymes used, act as endo-enzymes that randomly cleave internal α-1,4-glycosidic linkages in and , producing a mixture of oligosaccharides, dextrins, , and glucose. Beta-amylases, though less commonly applied in processing, function as exo-enzymes that sequentially remove units from the non-reducing ends of chains. This occurs under mild conditions, typically at a range of 5.5-7 and temperatures of 50-70°C, with reaction times of 30-60 minutes allowing sufficient breakdown without affecting the fibers of the fabric. The process begins with padding the fabric in an enzyme solution containing 0.5-2% on weight of fabric (owf), along with wetting agents and stabilizers, to ensure uniform impregnation and gelatinization of the size. The padded fabric is then incubated at the optimal (50-70°C) for 30-60 minutes, during which the enzymes catalyze the . Inactivation follows to stop the reaction and remove byproducts: this is achieved by heating to 90°C for 10-20 minutes or adjusting to an acidic , followed by hot washing to extract the soluble and glucose residues. For native , this method achieves desizing efficiencies exceeding 95%, as measured by reduced iodine coloration and improved fabric wettability. Key advantages of enzymatic desizing include its operation under mild, neutral conditions that minimize fabric damage compared to harsher chemical alternatives, preserving tensile strength and surface integrity of yarns. It also offers energy savings of 20-30% relative to traditional or oxidative methods due to lower temperatures and shorter cycle times, while generating biodegradable byproducts like glucose and that reduce effluent pollution. These attributes make it particularly suitable for high-quality woven fabrics. Since the 2000s, advancements in genetically engineered amylases—often derived from species via techniques—have expanded operational tolerances, enabling activity across broader (4.5-8.5) and (40-90°C) ranges to accommodate diverse lines. These engineered variants enhance efficiency on cotton-polyester blends by maintaining stability in mixed formulations, supporting integrated pretreatment workflows without compromising selectivity for .

Oxidative Desizing

Oxidative desizing employs chemical oxidation to degrade agents on fabrics, primarily through the generation of that target chains in starches and (PVA). Common oxidizing agents include (H₂O₂) at concentrations of 1-5% combined with (NaOH) for alkalinity, (KMnO₄), and (NaClO₂). In the case of H₂O₂, the alkaline environment activates the to form perhydroxyl anions (HO₂⁻), which decompose into highly reactive hydroxyl radicals (•OH). These radicals initiate oxidative cleavage of C-C bonds in the structure of starches or the carbon backbone of PVA, breaking down the sizing into smaller, water-soluble fragments for removal. The process typically involves batch immersion of the fabric in the oxidizing bath at temperatures of 80-100°C for 1-2 hours, followed by neutralization with agents like acetic acid to halt the reaction and prevent further oxidation. This method achieves high removal efficiencies of 85-95% for both starch-based and PVA sizes, making it suitable for blended sizing formulations on and / fabrics. is applied at lower concentrations (e.g., 0.5-2 g/L) often in acidic conditions for targeted oxidation, while (around 10 g/L) operates at 90-100°C for about 1 hour, particularly effective against synthetic sizes. One key advantage of oxidative desizing is its versatility in handling mixed or blended sizes, including those resistant to enzymatic breakdown, while providing ancillary scouring and bleaching effects. However, it carries risks of fiber degradation, such as 5-10% tensile strength loss in due to indiscriminate radical attack on chains, and requires high chemical dosages that can increase operational costs. Historically prevalent in 20th-century mills for its reliability in large-scale , modern applications incorporate stabilizers like sodium silicates or organic alternatives to control and minimize damage.

Acid Desizing

Acid desizing is a chemical method employed to remove starch-based agents from fabrics, particularly , by breaking down the structure into water-soluble components. This process utilizes dilute solutions of mineral acids, such as or , at concentrations ranging from 0.5% to 2%, with the bath maintained at a of 2 to 4. The acidic environment facilitates the cleavage of glycosidic bonds in the molecules, converting them into lower molecular weight dextrins that can be easily washed away. The treatment typically involves steeping the fabric in the or applying it via , followed by heating to 60–80°C for 30 to 90 minutes to accelerate the reaction. After the reaction period, the fabric undergoes thorough rinsing with to neutralize and remove residual acidity, preventing potential damage to the fibers. This method demonstrates high efficiency, often exceeding 90% removal of unmodified sizes, making it suitable for preparing fabrics for subsequent wet processing steps. One key advantage of acid desizing is its simplicity and reliance on low-cost , as it requires no specialized biological agents or complex machinery. However, the process has notable drawbacks, including the corrosiveness of the acids to processing and the risk of fiber tendering, which can result in strength losses of up to 15% if the treatment is excessive or control is inadequate. Acid desizing is commonly applied to and traditional fabrics where sizes predominate, with careful monitoring essential to minimize degradation of associated non-cellulosic components like . While primarily effective for natural -based sizes, it can also assist in solubilizing certain synthetic polymers when combined with other methods, though oxidative approaches are preferred for more resistant synthetics.

Removal of Water-Soluble Sizes

Water-soluble sizes, such as (PVA) and polyacrylates, are hydrophilic synthetic agents engineered for ready dissolution in , making their removal from woven fabrics a primarily physical extraction . These sizes are commonly applied to synthetic warps to withstand the mechanical stresses of high-speed . The desizing procedure relies on hot scouring at 70-90°C for 20-40 minutes to hydrate and dissolve the , typically incorporating non-ionic at 0.1-0.5% concentration to enhance , penetration, and dispersion of the solubilized material. This can be executed through continuous pad-wash systems, where fabric is padded with hot and passed through multiple wash boxes, or batch extraction in steamers or J-boxes, allowing dwell time for complete solubilization. The process requires no adjustment or chemical additives, achieving 95-98% removal as measured by or iodine tests on residual fabric. Efficiency is often verified by assessing in the wash liquor, which indicates the degree of dispersion and extraction. This method offers significant advantages, including minimal environmental impact due to the absence of harsh chemicals and low (BOD) in the , while preserving fabric by avoiding degradation of fibers. However, it is limited to water-soluble, hydrophilic sizes and proves ineffective for insoluble materials like starches, necessitating alternative desizing approaches in those cases.

Fermentative Desizing

Fermentative desizing is a biological process that employs microorganisms to degrade starch-based sizing agents on textile fabrics through microbial fermentation. In this method, bacteria such as Bacillus subtilis or molds like Aspergillus niger produce amylolytic enzymes, primarily α-amylases, which hydrolyze the starch polymers into soluble dextrins, maltose, and glucose, thereby facilitating the removal of the size without damaging the underlying fibers. The fermentation typically occurs over 24-48 hours at temperatures of 30-40°C and near-neutral pH (around 5.5-6.5), allowing the enzymes to act under mild conditions that mimic natural degradation processes. The process begins with steeping the sized fabric in an inoculum of the microbial culture, usually at 1-5% concentration relative to the fabric weight, in a bath that may be maintained under aerated or anaerobic conditions to promote microbial growth and enzyme secretion. This steeped fabric is then incubated for the fermentation period, after which it is rinsed to remove the degraded size residues. Historically, this technique has roots in pre-1900s textile traditions in India and China, where it was applied to cotton fabrics as early as 1857 and became widespread by 1912, relying on naturally occurring microbial cultures for low-cost preparation. One key advantage of fermentative desizing is its low-tech nature, requiring minimal equipment and the ability to utilize substrates like agricultural residues for cultivating the microbial inoculum, making it accessible in resource-limited settings. However, the method suffers from disadvantages such as prolonged processing times, potential inconsistency due to microbial contamination, and variable yields, which led to its in industrial applications after the in favor of more controlled approaches. In modern contexts, fermentative desizing finds niche applications in experimental processing of , where it achieves starch removal efficiencies of 80-90%, as monitored by reductions in fabric and residual levels assessed via the TEGEWA scale. This evolution toward purified enzymatic methods has largely supplanted whole-culture for greater precision and speed, as detailed in the enzymatic desizing section.

Environmental Considerations

Wastewater Impacts and Treatment

Desizing wastewater is characterized by high levels of (BOD), typically ranging from 1500 to 4000 mg/L due to starch-based sizing agents, and (COD) between 10,000 and 20,000 mg/L from degraded organic materials. These effluents also contain substantial , often exceeding 5000 mg/L, along with extremes—such as 4–5 in acidic processes or up to 12–14 in alkaline ones—arising from unrinsed desizing chemicals and breakdown products of synthetic or natural sizes. The environmental impacts of untreated desizing wastewater are significant, primarily through of water bodies caused by oxygen depletion from elevated BOD and , which disrupts aquatic ecosystems and promotes algal blooms. Residuals like from oxidative desizing further contribute to , harming and microorganisms by inducing and reducing . Globally, effluents, including those from desizing, account for about 20% of industrial , exacerbating these effects in regions with inadequate treatment infrastructure. Treatment strategies for desizing begin with primary to settle , reducing and initial organic load. Secondary biological treatment via processes then degrades organics, achieving up to 90% BOD removal through microbial action under aerobic conditions. Tertiary steps involve neutralization to stabilize within 6–9 and advanced or to eliminate remaining pollutants, ensuring compliance with discharge standards. Operational costs for these conventional methods generally range from $0.50 to $1.00 per 1000 L, influenced by plant scale and energy use. Regulatory measures enforce strict effluent limits to mitigate impacts, such as the EU's Urban Waste Water Treatment Directive requiring BOD below 25 mg/L for discharges to sensitive waters. Monitoring desizing effectiveness via the TEGEWA scale, which assesses residual size on fabrics through iodine staining (ratings 1–9, with 7+ indicating sufficient removal), helps prevent excessive pollutants from entering wastewater streams.

Sustainable Practices and Alternatives

The adoption of enzymatic desizing has gained prominence in the as a sustainable alternative to traditional chemical methods, primarily due to its ability to hydrolyze starch-based sizing agents under milder conditions. This process reduces chemical usage by replacing harsh acids and oxidants, while operating at lower temperatures (typically 50-80°C) and shorter durations, leading to significant energy savings and through fewer rinsing steps. As of 2025, the global market for enzymes, including those for desizing, is valued at approximately USD 457 million and is projected to grow at a (CAGR) of 6%. Innovative alternatives to conventional desizing include ultrasound-assisted methods, which leverage acoustic to enhance size removal efficiency, achieving up to 30% higher desizing performance compared to traditional exhaust processes while reducing chemical and energy inputs. Plasma treatment offers a dry, waterless approach, effectively degrading coatings on fabrics through atmospheric plasma exposure, thereby minimizing generation and matching the efficacy of enzymatic methods in improving fabric wettability and whiteness. Additionally, biodegradable sizing agents such as , derived from natural polymers, facilitate easier desizing via enzymatic breakdown and reduce overall environmental load by enabling closed-loop recycling in production. These sustainable practices contribute to a lower by curtailing energy-intensive operations and chemical effluents, aligning with standards like the Zero Discharge of Hazardous Chemicals (ZDHC) Manufacturing Restricted Substances List (MRSL), which promotes safer chemical management in wet processing. Case studies from illustrate practical implementation; for instance, a 2023 study in demonstrated complete starch removal using -derived at 60°C, while a 2024 Indian trial optimized enzymatic desizing with soapnut extract as a bio-surfactant, achieving 6.58% and enhanced fabric absorbency without synthetic additives. Despite these advantages, challenges persist, including higher upfront costs for procurement and optimization, as well as issues related to enzyme stability and consistent performance across large-scale operations. Ongoing research focuses on recombinant enzymes and immobilization techniques to address these barriers and broaden adoption.
