Antistatic high-elasticity bulk blended yarn

Abstract

The invention relates to the technical field of bulk blended yarns, in particular to an antistatic high-elasticity bulk blended yarn. Vinylon fibers are removed in a dissolved manner to obtain the bulk blended yarn, the bulk blended yarn is prepared from acrylic fibers and wool fibers and has a sheath-core structure, the blended mass ratio of the acrylic fibers to the wool fibers is 50%-70%:30%-50%, the vinylon fibers account for 10-40% of the total weight of the blended yarn before dissolution, the acrylic fibers are treated by acrylic oil agents, and the wool fibers are treated by antistaticfinishing agents. The acrylic fibers and the wool fibers are blended to form the bulk blended yarn and have good elasticity, so that a woven fabric is good in elasticity, the wool fibers are treatedby the antistatic finishing agents, so that the woven fabric has durability and antistatic properties, the antistatic properties of the fabric are improved, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of bulky blended yarn, in particular to an antistatic and highly elastic bulky blended yarn. Background technique [0002] With the rapid development of the economy and the continuous improvement of living standards, people's requirements for clothing are also constantly improving. Among them, thermal underwear, sweaters and other thermal clothing are required to have a better thermal effect, and it is also hoped that in the cold winter, physical activities will not be affected by wearing heavy clothes. [0003] To improve lightness and bulk, bulked yarns have been developed. The bulky yarn is spun by mixing high-shrinkage fibers and ordinary fibers, and the high-shrinkage fibers shrink to form a skin-core structure through wet heat treatment to increase air circulation space. For example, the patent document CN201459317U discloses a kind of melange-spun bulky yarn. By using undyed high-shrinkage fiber and...

Problems solved by technology

For example, the patent document CN201459317U discloses a kind of melange-spun bulky yarn. By using undyed high-shrinkage fiber and one or more dyed other fibers to blend, although the yarn bulkiness is improved, But there are still deficiencies; and in order to obtain the color mixing effect, it is necessary to adjust the color before swelling and to match the color after swelling. Subsequent wet heat treatment will produce changes, and the color cannot be corrected later

[0004] Another example is the patent document CN103097595A which discloses a bulky staple fiber single yarn obtained by dissolving and removing the water-soluble yarn from the composite twisted yarn in a hydrophilic solvent. The reverse twisting of the non-toxic yarn forms a conjugated double-ply yarn, so that the original staple fiber single yarn is untwisted and then twisted and wrapped in the outer layer of the water-soluble fiber. After the water-soluble yarn is removed in a hydrophilic solvent, the outer layer After untwisting, the staple fiber single yarn has a loose structure, poor fiber straightness, poor cohesion between fibers, and reduced yarn strength; at the same time, excessive twisting conditions will increase production costs; Straightness is only a residual form of the previous single yarn twist, which cannot achieve long-lasting bulk performance

[0005] The existing bulky blended yarn has poor elasticity and antistatic properties, and poor comfort, which limits its application to a certain extent
