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

Embodiment 1

[0031] Use 25% by weight of polyvinyl alcohol fiber, 15% by weight of high-shrinkage acrylic fiber (20% shrinkage in boiling water) and 60% by weight of ordinary acrylic short fiber (1.5% shrinkage in boiling water) as raw materials, mix → carding → combine Blending→roving→spinning→winding→closing and two-for-one twisting process to form two-for-one twisted yarn, then undergo hot water treatment at 95°C to remove polyvinyl alcohol fibers, and then dye under conventional conditions to obtain blended yarn. The specific performance parameters are shown in the table 1.

[0032] The specific conditions of the above-mentioned blended yarn processing procedure are as follows:

[0033] ① Mixing: fully mix evenly, and the blending rate is accurate. For loose fibers with multiple raw materials, layer them in a sandwich state, weigh and mix them in batches, and then go through no less than 2 wool bins or multi-bin blends to make a variety of loose fibers Raw cotton is mixed evenly. If ...

Embodiment 2

[0041]Use 10% by weight of polyvinyl alcohol fiber, 10% by weight of acrylic fiber with 25% shrinkage, 70% by weight of acrylic staple fiber with 1.5% shrinkage, and 10% by weight of ordinary viscose staple fiber as raw materials , mixed→carding→combining→roving→spinning→winding→synthesizing and two-for-one twisting process to form two-for-one twisted yarn, then undergo hot water treatment at 80~95℃ to remove polyvinyl alcohol fibers, and then dye to obtain blended yarn . The specific performance parameters of the obtained yarn are shown in Table 1.

[0042] The specific conditions of the above-mentioned blended yarn processing procedure are as follows:

[0043] Combination: final drawing weight 9.9g / m;

[0044] Roving: the total draft ratio is 9.5 times, and the roving weight is 1.05g / m;

[0045] Spun yarn: 21.5 times of total drafting ratio, 1.16 times of drafting ratio in the rear area; common branch twist coefficient K=60; all the other mixing, carding, winding, closing...

Embodiment 3

[0047] Use 10% polyvinyl alcohol fiber weight ratio, 45% polyester fiber weight ratio with 40% shrinkage rate and 45% ordinary cotton staple fiber weight ratio as raw materials, mix→carding→combining→roving→spinning→winding→ Two-for-one-twisted yarn is formed in the process of spinning and two-for-one twisting, and then treated with hot water at 80-95°C to remove polyvinyl alcohol fibers, and then dyed to obtain blended yarn. The specific performance parameters of the obtained yarn are shown in Table 1.

[0048] The specific conditions of the above-mentioned blended yarn processing procedure are as follows:

[0049] Combination: final drawing weight 9.5g / m;

[0050] Roving: the total draft ratio is 9.3 times, and the roving weight is 1.03g / m;

Abstract

The invention discloses a bulk blended yarn and a production method thereof. The bulk blended yarn is a staple fiber yarn having a skin core structure, wherein the staple fiber yarn is obtained by removing water-soluble polyvinyl alcohol fibers through dissolving, and the staple fiber yarn is formed by at least high shrinkage staple fibers and common staple fibers; meanwhile, the filling power of the bulk blended yarn is up to 90 % and more. The obtained bulk blended yarn is characterized in light weight and warm-keeping; the filling power is stable and durable; the bulk blended yarn is suitable for making sweaters, underwear, blankets, and the like.

Description

technical field [0001] The invention relates to a bulky blended yarn and a production method thereof, in particular to a bulky blended yarn which has better bulkiness and softness than other bulky yarns and can produce lighter and warmer garments at the same time Yarn and its production method. 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 spa...
