Embodiment

[0088] One, the formation mechanism and characteristics of the double-layer structure yarn of the present invention

[0089] (1) double-layer structure yarn formation mechanism of the present invention

[0090] Double-layer structure yarn formation mechanism and structural principle of the present invention are as follows:

[0091] Firstly, four kinds of staple fibers, including thermal storage and heating fiber, regenerated cellulose fiber, water-soluble vinylon and high-shrinkage acrylic fiber, are blended into yarn.

[0092] Secondly, the above-mentioned four-in-one blended yarn is treated with hot water to dissolve the water-soluble vinylon. At the same time, the high-shrinkage acrylic fiber also produces irreversible heat shrinkage, which shortens the axial length of the yarn and causes other fibers to swell and curl. The middle part of the thread is hollow, and the double-layer structure yarn is obtained, and its actual cross-sectional structure is as follows figure 1 ...

Abstract

The invention discloses a yarn spinning method of heat-accumulation and heating fiber blended and bulked double-layered-structure yarns. The yarn spinning method comprises the following steps: selection of raw materials and a blending ratio; a blended yarn spinning process; a yarn spinning process; a vinylon dissolving process. The formation of hollow parts of the double-layered-structure yarns actually comprises two aspects that in one aspect, the hollow parts are formed through dissolving water-soluble vinylon with hot water; in the other aspect, in a hot water treatment process, an irreversible heat shrinkage rate generated by high shrinkage acrylic fibers is more than a heat shrinkage rate generated by outer wrapping short fibers, so that the bulkiness and the hollow degree are also increased on the basis of previous hollow parts.

Description

technical field [0001] The invention belongs to the field of yarn processing, and in particular relates to a method for spinning heat-storing heating fiber / regenerated cellulose fiber / high-shrinkage acrylic fiber / water-soluble vinylon blended bulky double-layer structure yarn. Background technique [0002] The yarn production method of ordinary hollow thermal yarn is to blend water-soluble vinylon staple fiber and outsourcing fiber (or use water-soluble vinylon filament as yarn core and other fibers as outsourcing fiber to spin into core-spun yarn), and after fabric , and then treated with hot water to dissolve the water-soluble vinylon, so as to obtain hollow thermal yarn and its fabric. The fabric produced by this method has a certain degree of warmth retention, but only uses the hollow part of the yarn to prevent heat from escaping to achieve warmth. , and the strength of yarn and fabric is also low. Contents of the invention [0003] Purpose of the invention: In orde...
