Problems solved by technology

Therefore, the effect of preventing heat from escaping is not ideal, and it cannot achieve a better thermal insulation effect; for example, the thermal insulation fabric made of regenerative heating fiber spinning can release heat, but it does not have the best ability to prevent heat from escaping. , resulting in not really achieving the best thermal effect in the end

Abstract

The invention discloses a heat-retaining core-spun hollow knitted fabric and a preparation method thereof. The preparation method comprises steps: (1) Weaving process: preparing raw material cotton fibers, heat storage and heating fibers, hollow chemical fiber filaments, and modal fibers, Four-in-one blended core-spun double-layer structure yarn, hollow chemical fiber filament as the yarn core, weaved into a plain stitch and all plated structure; (2) pre-setting process: pre-setting the fabric prepared in step (1), and finalizing the shape The temperature is set at 180-195°C; (3) Dyeing process: the dyeing process includes pre-treatment, cotton dyeing and post-treatment processes (4) Drying: shake and dry after dyeing, and the drying temperature is 120-150°C; (5) Stenter setting: after drying, add softener again for final setting, the setting temperature is 150-190°C, and the speed is 18-25m / min. The heat-retaining core-spun hollow knitted fabric prepared by the method of the invention has a simple structure and a reasonable design, respectively endows the fabric with excellent heat storage, heat-preservation and softness properties under the condition of low dosage, and saves cost.

Description

Technical field[0001]The present invention relates to the field of knitted fabrics, and more particularly to a warm core hollow knit fabric and a preparation method thereof.Background technique[0002]With the continuous development of science and technology, in order to meet the problem of textile fabrics in people's different needs, all kinds of textile fabrics also play an increasingly important role in daily life.[0003]In the past, in order to improve the warm effect of the knitted underwear fabric, the conventional practice is to add the textile fabric, thickened, coating, which not only causes the fabric thickness, gas permeability, and greatly affects the texture of the fabric and the comfort of the fabric. In the past two years, there is also a development of thin warm fabrics, but the physical performance and warm performance of the product are often not ideal. If the warm fabric developed with hollow fibers is only to keep warm from escape from heat, it does not have heat ge...
