Embodiment 1

[0040] Paxter fiber is selected from top specifications, with a linear density of 2.22dtex, a length of 76mm, and a moisture regain of 0.7%; wool is selected with a fineness of 20um, a length of 53mm, and a moisture regain of 13%; PTT fibers are selected with a linear density of 1.40dtex, a length of 60mm, and a moisture regain of 0.6%. . At 20°C, the cationic dye Viocryl Red GRLS ZF 200% is used for printing and dyeing, among which Paxter tops are dyed, wool and PTT loose fibers are dyed, and then pre-baked at 80°C for 3 minutes, and then baked at 140°C for 3 minutes. The temperature is 20°C and the relative humidity is controlled at 65%. Weigh Pingpingjia (fatty alcohol polyoxyethylene ether) according to 0.4% of its fiber mass after strip dyeing, add water to dilute it according to 80% of fiber mass, and spray it evenly on the wool top for 8 hours; after dyeing wool, use Mix with the wool machine for 2 times, add MD-2 and crude oil according to 1% of the fiber mass, add wa...

Embodiment 2

[0042] Paxter fiber is made of top specification, linear density 3.33dtex, length 88mm, moisture regain 0.8%; wool fineness 23um, length 55mm, moisture regain 16%; PTT fiber linear density 1.60dtex, length 80mm, moisture regain 0.8% . At 25°C, the cationic dye Viocryl Red GRLS ZF 200% is used for printing and dyeing, among which Paxter wool tops are dyed, wool and PTT loose fibers are dyed, and then pre-baked at 100°C for 5 minutes, and then baked at 160°C for 5 minutes. The temperature is 25°C and the relative humidity is controlled at 80%. Weigh the antistatic agent Pingpingjia (fatty alcohol polyoxyethylene ether) according to 0.4%-0.8% of the fiber mass after the strip dyeing of Paisite wool tops, dilute with water according to 90% of the fiber mass, and spray evenly on the wool tops for placement 10 hours; after wool dyeing, mix it with a wool machine for 4 times, add MD-2 and crude oil according to 2% of the fiber mass, add water to dilute according to 90% of the fiber ...

Abstract

The invention relates to a preparation method of parster multi-component semi-worsted yarns, comprising the following steps of: (1) selecting fibers by combining performance requirements of a product; (2) dyeing parster wool top, loose wool fibers and PTT (polytrimethylene terephthalate) loose fibers with cationic dye respectively, performing preliminary drying for 3-5 minutes at 80-100 DEG C, and then carrying out sizing baking for 3-5 minutes at 140-160 DEG C to obtain the dyed parster wool top, loose wool fibers and PTT loose fibers; and (3) sequentially performing wool blending, cotton carding, drawing, roving, spinning and spooling procedures to obtain the parster multi-component semi-worsted yarns. In the invention, the preparation method is simple, safe and environment-friendly, and has low cost and high efficiency; and the multi-component semi-worsted yarns obtained in the invention has high strength, even yarn levelness, good elastic restoration and a wide market prospect.

Description

technical field [0001] The invention belongs to the field of preparation of multi-component semi-worsted yarns, in particular to a method for preparing Paisite multi-component semi-worsted yarns. Background technique [0002] Paster is a new type of polyester fiber, which belongs to modified polyester. It reduces the crystallization performance and glass transition temperature of polyester by introducing groups, so that the fiber has a super soft feel. Cationic dyes can dye dark colors under normal pressure boiling dyeing conditions, which conforms to the current fashion concept of low carbon, environmental protection and energy saving. The manufacturing process has no special requirements on equipment, and the cost is low, and industrialized production is easy to realize, and has a good application prospect in the textile field. [0003] Wool imported from Australia has natural luster, soft and plump feel, thin and curved fibers, good elasticity, and small and smooth scale...
