The attachment and fixation of dyes both depend on water as a carrier. Reactive dyes, direct dyes, and others must be dissolved in water and diffuse into the fiber interior through the tiny channels within the fiber—particularly the amorphous regions of cotton fibers. Therefore, good absorbency ensures that both the interior and exterior of the fiber are fully exposed to dyes and auxiliaries. If the fiber has poor absorbency (e.g., due to incomplete wax removal), the dye liquor cannot penetrate uniformly, easily resulting in surface color staining or uneven dyeing.

The key to improving the absorbency of knitwear fabrics lies in whether the chemical scouring during pre-treatment is thorough. Conventionally, high-temperature strong alkali (caustic soda) scouring combined with hydrogen peroxide bleaching has been used to effectively remove natural impurities such as waxes, pectins, and cottonseed hulls, exposing thehydrophilic cellulosic structure of the cotton fiber and thus fundamentally enhancing absorbency.

However, does good absorbency necessarily guarantee good dyeing results? yes. Good absorbency is a necessary prerequisite for good dyeing performance, but it is not a sufficient condition. If excessive hydrolytic damage or crystallinity changes occur during pre-treatment, even with excellent absorbency, the number of effective dye reaction sites may decrease, leading to lower color yield. The high-concentration, high-temperature, and prolonged use of caustic soda in conventional processes can cause excessive hydrolytic damage to cellulosic fibers. In other words, improved absorbency in conventional processes does not necessarily translate into superior dyeing results.

Baico Biotech BBT is a textile enzyme manufacturer in China, offering products including Bio-scouring enzymes and household detergent enzymes. To address this challenge, BBT has developed a Bio-scouring enzyme, RF838-K, which features highly active pectinase as its core component. It can efficiently decompose natural impurities such as pectin on the fibersurface, significantly improving absorbency while preserving the intact fiber backbone structure and the active hydroxyl groups in the amorphous regions, thereby effectively increasing dye adsorption sites and ensuring desired even dyeing performance. This not resolves the strength loss issues caused by conventional strong alkali treatment but also significantly enhances the fabric's color yield and color fastness. Furthermore, this enzyme product operates efficiently under relatively low temperatures and neutral pH conditions, effectively reducing energy consumption and water treatment costs, achieving both environmental and quality improvements.

BBT Enzyme is a biological solution ,developed to enhance the dyeing effect of fabrics. By rationally applying bio-enzymes, BBT redefines the benchmark for high-quality, high-efficiency, and eco-friendly pre-treatment, offering a more competitive and sustainable green solution for the pre-treatment processes of modern textile manufacturing.
