Problems solved by technology

[0002] At present, the thick thermal underwear fabrics on the market are often some brushed fabrics, usually chemical fiber fleece, and some patterned thermal underwear fabrics are double-layer fabrics with fluffy polyester yarns in the middle, brushed fabrics and double-layer fabrics with fluffy polyester yarns. They are all thick, too bloated to wear, and even inconvenient to move; some thinner thermal underwear fabrics are thinner elastic cotton, modal single-sided plain cloth, cotton fleece and ribbed cloth, etc., but they are not warm enough

Abstract

The invention discloses a light and thin heat preservation core-spun hollow knitted fabric. The light and thin heat preservation core-spun hollow knitted fabric comprises, by weight percentage, the raw materials of 24s cotton polyester sheath-core blending hollow yarn and 30D Dupont spandex, and the production process of the light and thin heat preservation core-spun hollow knitted fabric comprises the specific steps that material taking, yarn covering, gray fabric weaving, high-temperature preshaping, pretreatment agent preparation, pretreatment, neutralization and dyeing and shaping. Water-soluble vinylon fibers are dissolved away in the dyeing and finishing process, a hollow effect is formed, more air is reserved than that in conventional yarn, the better heat preservation effect is achieved, and meanwhile due to the fact that heart yarn is provided with a cross-shaped section, the good moisture guide function can be achieved, and the final fabric has the hollow heat preservation and moisture guide effect. Therefore, the produced fabric is thin and warm and has the moisture absorption and fast drying effects, and clothes are comfortable to wear due to the weaving structure with proper elasticity.

Description

technical field [0001] The invention relates to a knitted fabric, in particular to a light and thin warm-keeping core-spun hollow knitted fabric. Background technique [0002] At present, the thick thermal underwear fabrics on the market are often some brushed fabrics, usually chemical fiber fleece, and some patterned thermal underwear fabrics are double-layer fabrics with fluffy polyester yarns in the middle, brushed fabrics and double-layer fabrics with fluffy polyester yarns. They are all thick, too bloated to wear, and even inconvenient to move; some thinner thermal underwear fabrics are thinner elastic cotton, modal single-sided plain cloth, cotton wool and ribbed cloth, etc., but they are not warm enough. Therefore need to develop a kind of thickness, warming effect and the thermal insulation fabric that wearing comfort has both. Contents of the invention [0003] The object of the present invention is to provide a light, thin, warm-keeping core-spun hollow knitted ...
