Preparation method of acrylic wool viscose yarns

Abstract

The invention discloses a preparation method of acrylic wool viscose yarns. The preparation method comprises the following steps of (1) preparing mixed and pre-drawn card silver; (2) pre-drawing; (3)preparing acrylic card silver; (4) carrying out first drawing; (5) carrying out second drawing and final drawing; (6) performing roving forming; (7) performing spun yarn forming; and (8) finally, removing yarn faults from resultant yarns and rolling by using an automatic winder. The method has the advantages that the resultant yarns are low in knot, less in coarse and fine knots, less in hairinessand high in raw material utilization rate.

Description

technical field [0001] The invention relates to the technical field of fiber production, in particular to a preparation method of acrylic wool viscose yarn. Background technique [0002] Acrylic fiber is the trade name of polyacrylonitrile in my country. It is called "Orlon" and "Cashmiron" abroad, and DuPont in the United States is called Orlon. It is a synthetic fiber variety second only to polyester and polyamide. It is soft, light, warm, corrosion-resistant, and light-fast like wool-like staple fibers. Density is less than wool. Known as artificial wool. Although it is more than 10% lighter than wool, it is more than twice as strong. Not only will acrylic fiber not be moldy and moth-eaten, but it is also twice as resistant to sunlight as wool and 10 times more resistant than cotton. Therefore, it is especially suitable for making outdoor fabrics such as tents, gun covers, car covers, curtains, and curtains. [0003] Viscose fiber, a major species of man-made fiber....

AI Technical Summary

Problems solved by technology

This spinning method has high yarn neps, more coarse details, larger hairiness, poor quality, low raw material utilization rate of about 80%, low yarn production rate of 1.25%, increased cost, and spinning is more affected by temperature and humidity. Large, poor applicability, semi-finished products stick to the lap, difficult to form a web, the phenomenon of wrapping rollers is serious, and uneven mixing leads to uneven fiber distribution in the yarn body, uneven fabric surface after single dyeing, and large color difference on the fabric surface
