Embodiment 1

[0021] Use long-staple cotton and viscose fiber as raw materials to produce 40 lbs. The blended weight ratio is 70% long-staple cotton and 30% viscose fiber. The length of the long-staple cotton is 30-40mm and the fineness is ≤1.43 dtex, the process condition flow is,

[0022] The long-staple cotton is respectively combed: long-staple cotton→opening and cleaning→carding→pre-merging→rolling→carding→combed sliver; the viscose fiber is carded and carded: viscose Fiber→cleaning→carding→making viscose fiber slivers; then combed cotton sliver and viscose fiber slivers→drawing→roving→spun yarn→special yarn for thermal underwear.

[0023] Process requirements for blowing-carding and carding: cover plate-cylinder five-point gauge distance 0.2mm, 0.18mm, 0.15mm, 0.15mm, 0.18mm, licker-in roller-small drain bottom gauge inlet 5mm, doffer speed 16r / min , the tension draft is 1.37 times, the cotton board-licker-in interval is 0.3mm, the dust removal knife-licker-in interval is 0.38mm, and...

Embodiment 2

[0029] Use long-staple cotton and viscose fiber as raw materials to produce 45 lbs, blended with 72% long-staple cotton and 28% viscose fiber by weight for thermal underwear, wherein the long-staple cotton has a length of 30-40mm and a fineness of ≤1.43 dtex, process condition flow process is the same as embodiment one.

[0030] Process requirements for blowing-carding and carding: cover plate-cylinder five-point gauge distance 0.15mm, 0.13mm, 0.1mm, 0.1mm, 0.13mm, licker-in roller-small drain bottom gauge inlet 4.9mm, doffer speed 14r / min, the tension draft is 1.36 times, the interval between feeding plate and licker-in roller is 0.25mm, the interval between dust removal knife and licker-in roller is 0.33mm, and the speed of licker-in roller is controlled at 910r / min.

[0031] Combing process: the shortest feeding length of long-staple cotton is 5.59mm, the hardness of the separation cot adopts Shore A84 degree, the hardness of the drafting cot adopts Shore A80 degree, and t...

Embodiment 3

[0036]Use long-staple cotton and viscose fiber as raw materials to produce special yarn for thermal underwear with a blend weight ratio of 68% of long-staple cotton and 32% of viscose fiber. The length of the long-staple cotton is 30-40mm and the fineness is ≤1.43. dtex, process condition flow process is the same as embodiment one.

[0037] Process requirements for blowing-carding and carding: cover plate-cylinder five-point gauge distance 0.25mm, 0.23mm, 0.2mm, 0.2mm, 0.23mm, licker-in roller-small drain bottom gauge inlet 5.1mm, doffer speed 18r / min, the tension draft is 1.38 times, the interval between feeding plate and licker-in roller is 0.35mm, the interval between dust removal knife and licker-in roller is 0.43mm, and the speed of licker-in roller is controlled at 920r / min.

[0038] Combing process: the shortest feeding length of long-staple cotton is 5.63mm, the hardness of the separating cots is Shore A84, the hardness of the drafting cots is Shore A80, and the surfa...

Abstract

The invention discloses muslin dedicated for thermal underwear, and a manufacturing method thereof, wherein, long stapled mutton and viscose fiber are adopted as raw materials; a combing technology is adopted for the long stapled mutton to manufacture combed sliver; a carded cotton carding technology is adopted for viscose fiber to manufacture viscose fiber stripe; after drawing, roving and spun yarn are carried out to the combed sliver and the viscose fiber, high-woven yarn dedicated for the thermal underwear with the weight blend ratio of 68-72 percent of the long stapled mutton and 28-32 percent of the viscose fiber is manufactured. With the adoption of current spinning equipment, the manufacturing method can manufacture the high-woven yarn used for manufacturing high range clothing fabric or knitwear such as thermal underwear, and the like; besides, the number of fibrogen inside the cross section of the manufactured high-woven yarn can fully satisfy the need of cohesive force between fiber and fiber; the yarn strength is improved, thus being entirely capable of adapting to the requirements for manufacturing high range clothing fabric or knitwear such as thermal underwear, and the like.

Description

technical field [0001] The invention relates to a blended yarn, in particular to a special yarn for thermal underwear and a production method thereof. Background technique [0002] In recent years, the clothing fabrics in the world have changed rapidly and the popular period is short. Now the demand of consumers tends to be cotton viscose series, especially underwear and bedding, which require not only beautiful appearance, but also comfort and practicality. big. The cotton viscose fine count yarn can be used to weave high-grade clothing fabrics and knitted underwear, and the production efficiency is not only very considerable, but also the fabrics woven with cotton viscose fine count yarn can be used to make high-grade clothing fabrics or produce knitwear, especially thermal underwear produced The product is comfortable to wear, has good air permeability and moisture absorption, and is easy to dye and post-processing, and has been widely loved by people. The cotton-viscos...
