Production method of heat-accumulation and heating core-spun double-layered-structure yarn warm-keeping knitted fabric

Abstract

The invention discloses a production method of a heat-accumulation and heating core-spun double-layered-structure yarn warm-keeping knitted fabric. The production method comprises the following steps: selecting fiber raw materials; a knitted fabric production process flow specifically comprising the following steps: skeining yarns and dissolving vinylon: preparing bobbin yarns, reeling and skeining, dissolving the vinylon, washing, drying, spooling, knitting and dyeing and finishing a knitted fabric; or dissolving the vinylon from the fabric: preparing the bobbin yarns, knitting, dissolving the vinylon, washing and dyeing and finishing the knitted fabric. The heat-accumulation and heating core-spun double-layered-structure yarn warm-keeping knitted fabric disclosed by the invention has a triple warm-keeping function of heat-accumulation and heating fibers, inner hollow parts of double-layered-structure yarns, double-rib air layer tissues and the like; if chemical fiber filaments have hollow parts, the warm-keeping woven fabric has a quadruple warm-keeping function of the heat-accumulation and heating fibers, the inner hollows parts of the double-layered-structure yarns, the hollow chemical fiber filaments, the double-rib air layer tissues and the like, so that the warm-keeping effect of the knitted fabric is extremely improved under the condition that the thickness is not increased.

Description

technical field [0001] The invention belongs to the field of knitted fabric processing, and in particular relates to a production method of heat-storing heat-generating core-spun double-layer structure yarn to keep warm knitted fabric. Background technique [0002] In the past, in order to improve the thermal insulation effect of knitted underwear fabrics, the conventional method is to add layers and thicken the textile fabrics, which not only makes the fabrics thick and poor in air permeability, but also greatly affects the texture and wearing comfort of the fabrics. In the past two years, there have also been developments of light and thin thermal fabrics, but the physical properties and thermal performance of the products are often not ideal. For example, the development of thermal fabrics with hollow fibers only achieves warmth by preventing heat from escaping. Thermal fabric, although it can release heat, it does not achieve the best ability to prevent heat from escapi...

Problems solved by technology

[0002] In the past, in order to improve the thermal insulation effect of knitted underwear fabrics, the conventional method is to add layers and thicken the textile fabrics, which not only makes the fabrics thick and poor in air permeability, but also greatly affects the texture and wearing comfort of the fabrics.

In the past two years, there has also been the development of light and thin thermal fabrics, but the physical properties and thermal performance of the products are often not ideal

For example, the development of thermal fabrics with hollow fibers only achieves warmth by preventing heat from escaping. Thermal fabric, although it can release heat, it does not achieve the best ability to prevent heat from escaping, resulting in the failure to achieve the best thermal effect in the end
