Problems solved by technology

For example, a knitted fabric with excellent thermal insulation and underwear made of the knitted fabric disclosed in the patent document CN201010536626.6 are obtained by weaving weakly twisted long-staple cotton spun yarn and then fluffing. Good, but very limited improvement in insulation performance
[0004] Another example is the patent document CN201310313430.4 which discloses a wool blended fabric and its production method, which is obtained by weaving yarns formed from ultrafine anti-pilling acrylic fibers, wool and ordinary polyester staple fibers, and the resulting fabric has anti-pilling properties. , fluffy and warm, and feel like wool fabric, but in order to obtain the feel and luster of pure wool, the twist coefficient of the yarn is set too high, resulting in insufficient yarn bulkiness, and the final product is compared with ordinary acrylic 100% products. Warmth has no obvious advantage

Embodiment 1

[0038] Select the superfine acrylic staple fiber of 60% by weight of 0.6tex, the water-soluble polyvinyl alcohol fiber of 1.2dtex of 10% by weight and the viscose staple fiber of 1.2dtex of 30% by weight for use as raw materials, mix → comb → combine →Roving→spinning→winding process to form a blended yarn, wherein the imperial twist coefficient of the spun yarn in the spinning process is set to 2.5. The polyvinyl alcohol fibers were removed by hot water treatment at 95°C, and then dyed under conventional conditions to obtain blended yarns. The specific performance parameters are shown in Table 1.

Embodiment 2

[0040]40% by weight of 0.5tex superfine polyester staple fiber, 30% by weight of 1.4dtex water-soluble polyvinyl alcohol fiber, 20% by weight of 1.2dtex viscose staple fiber and 10% by weight of cotton staple fiber are used as raw materials , carry out mixing→carding→combining→roving→spinning→winding process to form blended yarn, wherein the imperial twist coefficient of the spun yarn in the spinning process is set to 3.0. The polyvinyl alcohol fibers were removed by hot water treatment at 95°C, and then dyed under conventional conditions to obtain blended yarns. The specific performance parameters are shown in Table 1.

Embodiment 3

[0042] Use 30% by weight of 0.7tex superfine acrylic staple fiber, 20% by weight of 1.2dtex water-soluble polyvinyl alcohol fiber and 50% by weight of 1.2dtex nylon staple fiber as raw materials, mix → carding → merge → Roving→spinning→winding process forms a blended yarn, wherein the imperial twist coefficient of the spun yarn in the spinning process is set to 2.5. The polyvinyl alcohol fibers were removed by hot water treatment at 95°C, and then dyed under conventional conditions to obtain blended yarns. The specific performance parameters are shown in Table 1.

Abstract

The invention discloses a weakly twisted blended yarn and a production method thereof. The weakly twisted blended yarn is obtained by blending superfine short fibers, water-soluble polyvinyl alcohol short fibers and other ordinary short fibers, and then dissolving and removing the water-soluble polyvinyl alcohol fibers. % or more, and the single filament fineness of ultra-fine short fibers is 0.5-1.0dtex. The obtained weak twist blended yarn has the characteristics of soft hand feeling, fluffy and warm, and is suitable for making sweaters and underwear.

Description

technical field [0001] The invention relates to a weakly twisted blended yarn and a production method thereof. Background technique [0002] With the continuous improvement of living standards, consumers' requirements for clothing are also constantly improving. Among them, thermal underwear, sweaters and other thermal clothing are required to have a light weight, fluffy and soft feel on the basis of having a good thermal effect. [0003] At present, in order to make the fabric light, fluffy and soft, most of the products on the market use yarns with high yarn count and low twist coefficient, combined with fluffing on one or both sides of the fabric to form air between the fabric and the human body. Layered technical means, and finally obtain thin and light, soft, and excellent thermal insulation underwear. For example, a knitted fabric with excellent thermal insulation and underwear made of the knitted fabric disclosed in the patent document CN201010536626.6 are obtained b...
