Knitted Fabric Dyeing – Enzyme Preparations
Deoxygenase XH-1926 is an industrial-grade enzyme preparation produced by deep fermentation of genetically modified Aspergillus niger. It is primarily used for biological decontamination following oxygen bleaching in textile dyeing and printing plants, effectively addressing the issue of “color mottling” caused by residual hydrogen peroxide that interferes with dyeing. This enzyme rapidly decomposes hydrogen peroxide into water and oxygen, exhibiting high specificity—acting exclusively on hydrogen peroxide while having no adverse effects on fabrics or dyes. The standard product has an activity of 50,000 U/mL.
Traditional scouring employs large quantities of caustic soda and other chemical agents, which not only damage the fibers but also pose environmental hazards. The drawbacks of conventional scouring include the use of chemicals, the need for multiple rinsing steps, the resulting burden on wastewater treatment, and the detrimental effects on the fabric itself. “Biological scouring” is an enzymatic process that is gentler than traditional scouring. This product is a formulated blend of multiple enzyme preparations, with alkaline pectinase as the primary component. Research has shown that pectin acts like a glue, binding impurities such as cotton wax to the cotton fibers; however, these can be degraded by alkaline pectin lyase, making it easier to remove residual wax during subsequent hot-water washing.
Wide-Temperature Desizing Enzyme WT-B
During the weaving process, yarns are typically sized to enhance weaving efficiency; among sizing agents, starch-based sizes are the preferred choice for cotton, cellulose fibers, and blended fabrics.
To ensure effective fabric pretreatment and the smooth execution of subsequent dyeing and other finishing processes, it is essential to thoroughly and uniformly remove sizing agents from the fabric. The removal of sizing agents enhances the fabric’s wettability, thereby achieving satisfactory dyeing and printing results. Inadequate removal of sizing agents can lead to uneven dyeing, inter-batch color variations, and defects in printing.
High-concentration desizing enzyme WT-B is a broad-temperature amylase that effectively removes starch-based sizing agents. It acts exclusively on starch sizes and therefore does not adversely affect the fibers.

Viscose Polishing Enzyme 6000L
Viscose Polishing Enzyme 6000L is a cellulase preparation produced by genetically modified microorganisms. Developed specifically to meet the polishing requirements of man-made cellulosic fiber textiles, it effectively addresses the poor pilling resistance and excessive fuzziness commonly found in fabrics made from such fibers.
Xianteli 3000L is produced by liquid fermentation and membrane filtration ultra-concentration and purification of genetically modified, non-pathogenic microorganisms, resulting in a highly concentrated liquid acidic cellulase.
Xianteli 8000L is an easy-to-use neutral polishing enzyme with a broad pH operating range (pH 5.0–8.0).
Its most significant feature is the ability to combine dyeing and polishing in a single bath, thereby saving time, reducing energy consumption, substantially lowering production costs, and achieving energy conservation and emission reduction.
