Technical Field
The application relates to the technical field of fabric spinning, in particular to a preparation process of a nylon-polyester blended fabric with a cool feeling.
Background
The polyamide fiber is a trade name of polyamide fiber and is commonly called nylon. The polyamide fiber is a general name of a fiber with a C9-NH group on a macromolecular chain, and the main varieties of the polyamide fiber are polyamide 6 and polyamide 66, and the tradenames of the polyamide fiber are polyamide 6 and polyamide 66. The nylon fiber is mainly made of filament, and a small amount of short fiber is mainly used for blending with cotton, wool or other chemical fibers. The wear resistance of the nylon fiber is far stronger than that of cotton fiber, wool and viscose. However, the nylon fiber has low modulus and poor crease resistance compared with terylene, and limits the application of nylon in the field of clothing. The moisture absorption of the nylon fiber is higher than that of the terylene, and the moisture regain of the nylon 6 and the nylon 66 under the standard condition is 4.5 percent.
In the related technology, chinlon and terylene are often blended to be used as sportswear, outdoor jacket and the like, and the moisture absorption of the chinlon is stronger than that of the terylene, so that one surface of the chinlon faces to the skin of a human body. The dacron has high crease resistance and good drapability, but has poor moisture absorption, so that one surface of the dacron faces to the outside far away from the skin of a human body. When people wear the sportswear made of the nylon fabric in daily life to exercise, the nylon fabric is in contact with the skin, once the temperature difference between the skin of a human body and the nylon fabric is balanced, the nylon fabric and the skin lose the cool feeling, and the comfort of the human body when the nylon fabric is worn is reduced. Therefore, a preparation process of a nylon and polyester blended fabric with a cold feeling is urgently needed.
