China Best Price Factory 100% Cotton Cross Acrylic Stitch Thread Wool Knitting Yarn

Due to the compact structure of acrylic fiber, its hygroscopicity is low, and the moisture regain is about 1.2-2.0% under general atmospheric conditions. Its dyeing property is poor, and it is improved after the introduction of the second and third monomers. The fiber is cooled rapidly under tension, and the fiber is fixed under the condition of large internal stress. This kind of fiber has latent shrinkage after heating, that is, thermal resilience.

Acrylic fiber has excellent light resistance and weather resistance, and is the best among common textile fibers. Exposed outdoors for one year, its intensity only decreases by 5%, and its resistance to sunlight is also one time greater than that of wool and 10 times greater than that of cotton. Therefore, acrylic fiber is most suitable for outdoor use. Acrylic fiber has good heat resistance and ironing temperature is 130-140 ℃. It is not moldy and not afraid of moths, but has poor wear resistance and dimensional stability. The relative density of nylon is small.
