Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, and in particular to an anti-pilling acrylic fabric and a production method thereof. Background Art

[0002] Acrylic fabrics have been developed in the market for many years. There are pure spinning and blending. Acrylic can be blended with cotton, viscose, polyester and other fibers to make the yarn have a certain fluffy and wooly feel, thus obtaining a certain warmth retention. However, most of the acrylic used in the market is ordinary acrylic, which has a certain degree of fluffiness and wooly feel, and can partially replace wool, so that the subsequent fabric has a certain warmth retention. However, its anti-pilling performance is insufficient. In the case of the warmth retention performance of ordinary acrylic, the anti-pilling and heat generation functions of acrylic fiber are increased, and the spinnability and use of these functional acrylic fibers are studied.
