Modal fiber is a type of cellulose fiber, so its dyeing performance is similar to that of viscose fiber and cotton fiber. It can be dyed with reactive dyes or direct dyes.
However, due to the special nature of Modal fiber, it is sensitive to dye additives and has a strong affinity for reactive dyes. It has a high initial dyeing rate, short half dyeing time, and once the dye is applied, it is not easy to transfer, which can easily lead to color spots and streaks. The dyeing process curve shows that JINLVL, a cotton leveling agent, is a special non/anionic surfactant complex that has excellent wetting, dispersion, and slow dyeing properties. It is resistant to alkali, salt, and hard water, has low foaming, and can increase the solubility of dyes, effectively preventing color spots and defects. Modal fabric is dyed using the above process, resulting in uniform color and bright hues. The fabric surface has no creases, minimal fuzz, and a soft and smooth feel.
The post finishing of fabrics is crucial, and the quality of the product largely depends on the quality of the post finishing. Modal fibers have a uniform circular cross-section, and the adhesion between fibers is weaker than that of cotton fibers. If traditional amino silicone oil smoothing and softening agents are used for post finishing, it often reduces the adhesion of the yarn to some extent, making the fabric surface more prone to pilling and pilling. Therefore, the quality of the softening process and softener will determine the texture of the fabric and the style of the product. The biggest drawback of Modal fabric is pilling, which is related to static electricity. Therefore, anti-static agents and anti pilling agents can be added in the post finishing process for composite finishing. Modal and spandex fabrics themselves have a full and soft hand feel, good drape, and luster. In order to further improve the product grade and give the fabric a soft and smooth hand feel, after multiple tests, the following soft formula can be selected to give the fabric a special elastic hand feel while having good hydrophilicity, and to give it a sense of body and bone.
Modal fiber is a type of regenerated cellulose fiber that not only has the characteristics of natural fibers, but also some synthetic fibers. It is non-toxic, pollution-free, biodegradable, and is a green and environmentally friendly fiber with its unique wearability; The modal fiber structure determines that the fabric surface has many feathers, and prolonged wet heat treatment is more likely to expose the fiber yarn ends, making them prone to pilling during use. Polishing treatment is the use of cellulase to remove the fuzz on the surface of fabrics, making the fabric surface smooth and even, thereby reducing the occurrence of pilling. If modal/spandex knitted fabric is dyed with dull colors, the pre-treatment does not require high whiteness of the fabric surface, and only needs to be boiled to remove spinning oil and wax. Polishing treatment can be performed before and after dyeing. Modal fabrics with added spandex are prone to scratches, creases, unstable width and quality during dyeing and finishing processes, and technical problems such as fuzz and pilling on the fabric surface. Choosing the appropriate processing technology is the most crucial.
Modal and spandex fibers treated with multifunctional pretreatment agents JINSOUR@X After boiling, the fiber strength is less damaged, the fabric surface is less prone to pilling, and the original characteristics of the fiber can be maintained, avoiding damage to Modal fibers by strong alkali pretreatment. Add anti-static bath softener in both pre-treatment and dyeing processes JINS0T@988 It can prevent fabric from scratching, snagging, creasing, and uneven dyeing throughout the entire processing process. Add cotton leveling agent JINLVL @ during the dyeing process to disperse the dye evenly, resulting in a uniform color and bright hues of the dyed fabric. Using silk like fabric finishing agents during the softening process JINSOT@WNS This further enhances the hydrophilicity, fullness, softness, and smoothness of the fabric, as well as its anti-static properties, thereby improving the wearability of the product. Strengthen post finishing, such as adding anti pilling agents, to further improve the wearability of the fabric.
