Embodiment 1

[0030] combine Figure 1 to Figure 5 , to describe this embodiment in detail. The stretchy wool blended yarn involved in this embodiment includes stretchy silk fiber, worsted Basolan wool, and anti-pilling acrylic fiber. The stretchy silk fiber is a spring-like spiral curl, with a large degree of curl, good elasticity and resilience. Anti-pilling acrylic can greatly improve the anti-pilling properties of blended yarns. As a result, the sweater prepared by the elastic silk wool blended yarn will hardly appear bulging in the hanging amount, and will not elongate due to the influence of gravity when hanging.

[0031] Further, the stretch fiber accounts for 40% by weight of the blended yarn, the worsted Basolan wool accounts for 30% by weight of the blended yarn, and the anti-pilling acrylic fiber accounts for 30% by weight of the blended yarn. The weight percentage is 30%.

[0032] This embodiment relates to a production process of elastic silk wool blended yarn, the preparat...

Embodiment 2

[0050] The difference between the production process of the elastic silk wool blended yarn involved in this embodiment and the first embodiment is that it also includes a dyeing process, and the dyeing includes the following steps:

[0051] Wind the prepared spun yarn onto a dyed plastic bobbin with holes, the bobbin used is cylindrical; the yarn density of the bobbin is controlled at 0.23-0.25g / cm 3 ; Rotate the bobbins layer by layer on each dye solution spray column on the dyeing creel, and fix the layers with spacers; then place the dyeing cage full of bobbins in a sealed bobbin vat; The weight of the yarns on the root dye spray column is the same and the arrangement is uniform;

[0052] For pre-dyeing treatment, inject the pre-dyeing treatment solution into the dye vat according to the bath ratio of 1:12-15, and the pre-treatment solution contains 40-50ml / L of 30% hydrogen peroxide, 4-5g / L of Sodium caramelate, 1-2g / L penetrant JFC, hydrogen bond breaker with a molar vol...

Abstract

The invention discloses a comfortable stretch yarn and wool blended yarn. The comfortable stretch yarn and wool blended yarn is characterized by comprising comfortable stretch yarn fibers, worsted basolan wool and anti-pilling acrylic fibers. The invention further discloses a production technology of the comfortable stretch yarn and wool blended yarn. The production technology of the comfortable stretch yarn and wool blended yarn sequentially comprises the steps of preparing comfortable stretch yarn and acrylic fiber blended cotton slivers, preparing worsted basolan wool tops, drawing, roving and spinning; the preparation of the comfortable stretch yarn and acrylic fiber blended cotton slivers comprises an opening picking process and a carding process; in the opening picking process, the comfortable stretch yarn fibers and the anti-pilling acrylic fibers are subjected to first-time blowing, mixed fibers obtained after first-time blowing are packaged, and second-time blowing is carried out. According to the comfortable stretch yarn and wool blended yarn and the production process thereof, after the prepared blended yarn is made into a sweater, the resilience of the sweater can be greatly improved. And when the sweater is hung, bumps are hardly generated, so that the shape preserving property of the sweater is good.

Description

technical field [0001] The invention relates to the technical field of yarn preparation, in particular to a wool blended yarn with elastic stretch silk and a production process thereof. Background technique [0002] Shu elastic silk is a kind of functional fiber produced by DuPont Company in the United States. Shu elastic silk fiber is skin-friendly, soft, and has good elastic recovery. Spandex yarn breaks like spandex, has good wrinkle resistance and shape retention performance, and the surface of stretchy silk fiber is not as smooth as polyester, and the cross section is not cylindrical, but irregular polygonal. The cohesion force between fibers is greater than that of polyester fiber, so stretchy silk It will not pill like polyester, and the dyeing performance of stretch yarn is also very good, and the color of the fabric can be very bright, so many properties of this fiber are better than ordinary polyester, but its air permeability and moisture permeability are worse th...
