Pilling, uneven dyeing, and dull fabric luster — these are common quality issues frequently encountered in dyeing factories. These problems can often be traced back to the polishing stage during pre-treatment. If the surface fiber pillings are not effectively removed through polishing, subsequent dyeing processes will fail to compensate for the loss of luster caused by a rough fabric surface. These pillings also negatively affect the consumer's tactile experience during use. Therefore, polishing is not only an aesthetic requirement to improve fabric luster, but also a technical necessity to ensure dyeing uniformity and finished product durability.
The pre-treatment process for towel fabric includes desizing and bio-scouring. If our bio-scouring enzyme product RF838-W is applied in the pre-treatment process for dyeing, an additional bio-polishing step using neutral cellulase is still required before adding dyes. To make the entire pre-treatment workflow morestreamlined and efficient, Baico Biotech has developed RF838-W(D) —an innovative enzyme formulation that integrates desizing, scouring, and bio-polishing into a single bath, built upon the proven performance of RF838-W.
RF838-W(D) is also a complex enzyme system composed of amylase, cellulase and pectinase, working synergistically. Under optimal conditions at 55°C for 60 minutes, these biological enzymes efficiently remove starch sizes and impurities from the fabric, while simultaneously performing bio-polishing to eliminate surface pillings. After this treatment, fabric whiteness is improved.
Compared to the two-step process using RF838-W for scouring followed by a separate cellulase polishing step, RF838-W(D) consolidates the two processes — originally requiring a total of 90 minutes (30 minutes for scouring + 60 minutes for polishing) — into a single 60-minute step, achieving a 33% reduction in processing time. When benchmarked against the conventional high-temperature, strong-alkali process (operating at 70°C), RF838-W(D) lowers the reaction temperature by 15°C, resulting in substantially reduced energy consumption.
However, the value of RF838-W(D) extends far beyond simple "time reduction". Its comprehensive advantages across multiple dimensions are even more remarkable:
In terms of fabric quality, RF838-W(D) delivers stable whiteness and excellent capillary effect, creating a uniform adsorption substrate for subsequent dyeing. This ensures improved dyeing performance and eliminates the risk of fiber damage commonly associated with harsh alkaline conditions. Furthermore, the enhanced pore structure is particularly beneficial for good absorbency in towels, a key quality parameter for end-users.
On the environmental front, this innovative enzymatic process greatly cuts the use of caustic soda and chemical agents, leading to a marked reduction in wastewater COD and other parameters, and consequently lowering the factory's wastewater treatment costs.
RF838-W(D) represents a substantial upgrade in textile pre-treatment — driving the industry toward "one-bath, multi-effect, lower-temperature, time-saving,and cleaner production." It offers dyeing factories a sustainable solution that balances quality, efficiency, and economic benefits. For textile companies looking for a reliable enzyme supplier, it ’ s undoubtedly the ideal choice.
