Brief Introduction Of Dyeing Process Of Modal Fiber

Modal fiber is a kind of cellulose fiber, so it has similar dyeing properties with viscose fiber and cotton fiber. It can be dyed by reactive dyes and direct dyes.

However, because of the specificity of modal fiber, it is sensitive to dyes and auxiliaries, and has strong affinity for reactive dyes, high initial dyeing rate and short dyeing time. Once dyes are dyed, it is not easy to pfer dyes, and easy to produce colored flowers and splashes.

The levelling agent JINLVL for cotton is a special non / anionic surfactant compound. It has excellent wetting, dispersing and retarding properties. It is alkali resistant, salt resistant, hard water resistant, low foaming, and can increase the solubility of dyes, and effectively prevent coloration and color defects.

Modal dyed fabric is dyed evenly and brightly. The cloth has no creases and less hair. It feels soft and smooth.

Fabric finishing is very important. The quality of products depends largely on the quality of finishing.

The cross section of modal fiber is uniform and circular, and the cohesion between fibers is worse than that of cotton fibers. If the traditional amino silicone oil softening agent is used for finishing, it will more or less reduce the cohesion of the yarn and make the fabric surface easier to pilling.

Therefore, the quality of soft technology and softener will determine the handle and style of the fabric.

The biggest drawback of modal fabric is pilling, and pilling is related to static electricity.

Therefore, antistatic agent and anti fuzzing agent can be added in the finishing process.

Modal and spandex fabric itself has plump and soft handle, good draping and luster. In order to further improve the grade of products and give the fabric soft, smooth and waxy feel, after many experiments, the following softening formula can be used to make the fabric obtain special shiny feel with good hydrophilicity and have a sense of body and bones.

It is a regenerated cellulose fiber, not only has the characteristics of natural fibers, but also has some characteristics of synthetic fibers. It is non-toxic, pollution-free and degradable. It is a green environment-friendly fiber and has its unique wearability. Modal fiber structure determines the surface hairiness of fabrics. Prolonged wet heat treatment makes it easier to expose the ends of fiber yarns and easy to pilling in the course of taking.

The polishing process is to remove the fuzz on the surface of the fabric by cellulase and make the fabric surface smooth and smooth, thereby reducing the phenomenon of hair lifting.

Romodel / Spandex Knitted fabric is dyed with dull colors, but the pretreatment does not require high whiteness of the cloth. It only needs to be scoured to remove spinning oil and wax.

Polishing treatment can be carried out before and after dyeing.

In the process of dyeing and finishing, the modal dyed fabrics with spandex are prone to abrasions, creases, and width, and the quality of fabrics is unstable. It is easy to produce Mao Yu and easy pilling on the surface of fabrics.

Choosing the right processing technology is the most important.

Modal

After the pretreatment of the multifunctional pretreatment agent JINSOUR@X, the fiber strength damage is small, the fabric surface is not easy to pilling, and can maintain the original properties of the fiber, avoiding the damage of modal alkali pretreatment to modal fiber.

In the pretreatment and dyeing process, the softener JINSOT@988 added to the antistatic bath can prevent the fabric from abrade and thread in the whole process, resulting in creases and uneven dyeing.

Add dye leveling agent JINLVL@ to the dyeing process to disperse the dyestuff evenly. The dyed fabric is uniform in color and bright in color.

The use of the silk like fabric finishing agent JINSOT@WNS in the soft treatment process can make the fabric get better hydrophilic and plump, soft waxy, slippery feel and antistatic function, and improve the performance of the product.

After finishing, such as adding anti pilling agent, the wearability of fabric is further improved.
