Textile Enzymes

In recent years, the textile industry has faced increasing pressure to reduce its environmental footprint while maintaining high product quality and managing rising production costs. As sustainability becomes increasingly important, the industry is turning to innovative solutions, with enzymes playing a key role in transforming traditional processes. Creative Enzymes offers a range of specialized enzymes for the textile industry, including neutral cellulase for fabric, catalase for bio-washing, mid-temperature desizing enzyme, alkaline pectinase for bio-scouring, etc. Our selection covers every step of the textile production process. Discover with us the benefits of textile enzymes!

Applications of Enzymes in Textile Processing

Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required. They are highly specific, meaning that they target specific substrates - such as starch, cellulose or peroxide - depending on the type of enzyme. This specificity allows precise control of textile processing, minimizing the risk of unwanted side effects. Enzymes operate under mild conditions, such as neutral pH and moderate temperatures, which conserve energy and protect fiber integrity.

Enzymes are used at various stages of textile production to provide specific benefits that cannot be achieved by traditional chemical methods. Key applications include:

Desizing

Desizing is the process of removing the size (a protective coating) applied to yarns before weaving. Traditional methods use harsh chemicals, but enzymes such as amylases offer a more sustainable solution. Amylases break down starch-based sizes into smaller, water-soluble molecules, making them easier to remove during washing. Enzymatic desizing is gentler on fibers, reduces water and energy consumption, and improves fabric quality.

Enzymatic Bio-Stoning

Enzymatic bio-stoning is used to replicate the stone-washed effect, giving denim a worn look without the use of abrasive stones. Cellulases, specifically endoglucanases, break down cellulose fibers on the fabric surface, creating a faded, soft texture. This process eliminates the need for physical stones, reducing wear on machinery and minimizing fiber damage.

Bio-Polishing

Bio-polishing improves the surface finish of fabrics by removing protruding fibers that cause pilling. Cellulases target and break down microfibrils of cellulose on the fabric surface, resulting in a smoother finish. Bio-polishing improves fabric softness and durability while reducing the likelihood of pilling.

Bio-Scouring

Bio-scouring is used to clean natural fibers such as cotton by removing impurities such as pectins, waxes and fats. This step is critical to improving fabric absorbency and dye uptake. The primary enzymes used in bio-scouring include pectinases, lipases and xylanases. Pectinases break down pectin, a complex carbohydrate found in plant cell walls, helping to remove it from the fibers. Lipases target and break down fats and oils present on fibers, while xylanases can break down xylans, another type of carbohydrate found in plant cell walls, aiding in the cleaning process.

Peroxide "Killer" Process

The peroxide "killer" process is used in textile bleaching to neutralize residual hydrogen peroxide after bleaching, preventing it from reacting with dyes. Catalases break down hydrogen peroxide into water and oxygen, ensuring complete removal of residual peroxide. This enzymatic process improves dye uptake and color fastness while reducing the need for additional washing and chemical treatments.

Enzymes for Specific Conditions and Fabrics

In the textile industry, enzymes are tailored to function effectively at specific temperatures and are selected based on the type of fabric and the desired outcome.

Low-temperature enzymes are effective at temperatures around 20-30°C (68-86°F). Cold-active amylases are used in desizing to break down starches at lower temperatures, reducing energy consumption. Cold-active cellulases are ideal for bio-polishing and enhancing the surface quality of fabrics at lower temperatures, minimizing fiber damage. Mid-temperature enzymes operate efficiently between 40-60°C (104-140°F). Mid-temperature desizing enzymes are used to remove starch sizes from fabrics during desizing, while mid-temperature cellulases are used in bio-polishing and stone-washing processes. High-temperature enzymes function well at temperatures above 60°C (140°F). Thermophilic cellulases are used in processes such as bio-stoning to achieve a worn look on denim, and high-temperature pectinases are effective at higher temperatures for bio-scouring to break down pectin and other impurities in cotton fibers.

Different enzymes are used for different materials because of their characteristics. For denim, cellulases (endoglucanases) are used in the bio-stoning process to create a faded, worn appearance; and laccases are sometimes used in combination with cellulases to enhance color and texture effects on denim. For cotton, pectinases are essential for bio-scouring cotton to remove pectin and other impurities to improve dye uptake and fabric quality, while cellulases are used for bio-polishing to reduce pilling and improve fabric softness and smoothness. In wool, proteases are used to remove excess grease and dirt from wool fibers while maintaining fiber integrity. They help clean and prepare wool for dyeing. And for synthetics, lipases are used to break down oils and fats on synthetic fibers, aiding in the cleaning and finishing process; catalases are used in the peroxide "killer" process to remove residual hydrogen peroxide after bleaching, ensuring effective dyeing and color fastness.

Each enzyme is selected based on its compatibility with the specific fabric and processing conditions, optimizing performance while minimizing environmental impact.

The Development Prospect of Enzymes in the Textile Industry

The future of enzymes in the textile industry is bright, driven by continued advances in biotechnology and a growing emphasis on sustainability. Key trends and developments include:
