Auxiliaries for Wool and Nylon
Wool fiber is soft and elastic, can be used for the production of wool, wool, blanket,
wool felt and textiles. The products feel rich, warm and good, comfortable to wear.
The characteristics of sheep wool accounted for a large proportion in the textile raw
materials. Wool textile industry is an important raw material, featuring in good
elasticity, strong absorption and warm. Wool products can be chemically processed to
improve the quality.
Nylon fiber, also known as polyamide fiber, has many excellent properties. The
appearance of nylon takes on an altogether new aspect of textile. It is not only a major
breakthrough in synthetic fiber industry, but also a very important milestone in polymer
chemistry. Through researching the dyeing process, the influence factors of dye rate
include the initial dyeing temperature, heating rate, holding time, pH value of dye
solution, dosage of auxiliaries for nylon and the operating method, etc. Improper
control of these factors will increase the probability of dyeing unevenly. Therefore, it is
necessary to strictly control the dyeing process to improve the grade of dyed nylon
fabric.
As for auxiliaries for nylon and wool, retarding agent, fixing agent and anti yellowing
agent are the commonly used textile chemicals.
Retarding agent can be adsorbed by nylon and wool by priority in the dyeing process,
thus reducing the affinity of fabirc to dye and achieving the purpose of evenly dyeing.
Due to the non-toxic and pollution-free, retarding agents are environmental friendly
textile auxiliaries.
Fixing agent is to improve the color fastness of the wool and nylon. It can form
insoluble coloration with dye on the fabric to improve wash and perspiration fastness.
Also it can enhance the color brightness.
Yellowing resistant agent is one of the special auxiliaries for nylon and wool with a
special effective ingredient that can effectively remove silicone oil and mineral oil on
the fiber in the washing process, with high temperature and yellow stain resistance.
