Embodiment 1

[0018] Siro spun smooth yarn - yarn for knitting, specification 32 s , JC / EKS ratio is 85% / 15%.

[0019] Raw material: EKS is 1.7dtex*38mm; JC grade is 2.2, and the main body length is 29mm.

[0020] Process route: see attached figure 1 ,

[0022] JC: Cotton plucking machine-opener-lapping machine-carding machine-drawing frame-sliver coiling machine-combing machine and then mix EKS raw sliver with JC combed sliver And - mix three and - roving, and then merge the same two groups of rovings - spun yarn.

[0023] Among them, the blending of EKS and combed cotton adopts the method of drawing and mixing. For EKS staple fiber, it is required that the blowing beater form of pre-spinning is best with comb needle, and the comprehensive beater of the lapping machine is changed to the comb beater, and the striking speed is reduced from about 900r / min to 650 / min. The state of the card clothing should be kept in good condition, ...

Embodiment 2

[0026] Heating fiber and cotton fiber blended knitting yarn, specification 42 s , JC / EKS is 60% / 40%.

[0027] Raw material: EKS is 1.7dtex*38mm; JC grade is 2.2, and the main body length is 29mm.

[0028] Process route: see attached figure 1 ,

[0031] Among them, the blending of EKS and combed cotton adopts the method of drawing and mixing. For EKS staple fiber, it is required that the blowing beater form of the pre-spinning is best with the comb needle, and the comprehensive beater of the lapping machine is changed to the comb beater, and the striking speed is reduced from about 900r / min to 710 / min.

Embodiment 3

[0034] Heating fiber and acrylic fiber blended knitting yarn, the specification is 38 s , Anti-pilling acrylic fiber / EKS is 70% / 30%.

[0035] Raw materials: EKS: 1.7dtex*38mm; double-resistant acrylic: 0.9dtex*38mm

[0036] Process route: see attached figure 2 ,

[0038] Among them, the blending of EKS and acrylic fibers is in principle mixed with cotton boxes. Because the double-resistant acrylic fibers are fine-denier acrylic fibers, the focus of the work is to reduce the generation of short fibers and control the neps. For EKS staple fiber, it is required that the blowing beater form of the pre-spinning is best with the comb needle, and the comprehensive beater of the lapping machine is changed to the comb beater, and the striking speed is reduced from about 900r / min to 680min.

Abstract

This invention relates to a blended spun yarn and a technology to produce it. The blended spun yarn is formed from heating fabric and cotton fibre or acrylic fibre. The manufacturing technology uses the common device of the cotton mill, characterized in that it uses the drawing mixing method to blend the heating fabric and combed cotton, while uses the hopper mixing method to blend the heating fabric EKS and the acrylic fibre. The beating speed of the beater in the making process will decrease to 650-750r / min, licker-in speed is 450-500r / min, cylinder speed is 180-210r / min, shuttering speed is 80-100mm / min, and the mixing radical is best to be eight, the stator of rove is 3.8-4.2g / 10m. The technical project can allocate the best processing parameter and get the stable and good textile.

Description

technical field [0001] The invention relates to the field of cotton spinning engineering in the textile industry, in particular to a blended yarn of heating fiber, cotton and acrylic staple fiber and a production process thereof. Background technique [0002] Heating fiber is a cross-linked acrylate fiber, which is a new type of synthetic fiber with excellent moisture conductivity. The heating fiber has the function of absorbing the moisture (sweat) produced by the human body to generate heat, which increases the temperature of the space, and can quickly release the absorbed moisture to the outside, making people feel warm and comfortable. In recent years, some chemical fiber enterprises dedicated to the research of new thermal fibers mainly use the properties of hollow fibers and fibers containing substances that emit and absorb far-infrared rays to prevent the heat generated by the body from escaping to achieve the purpose of heat storage and warmth. It uses acrylate poly...
