Embodiment 1

[0021] 1) Selection of raw materials: 14.5tex pure cotton combed yarn is selected for the outer layer of the fabric; nylon filament is selected for the inner layer, and its single fineness is 50D.

[0022] 2) Machine knitting: the fabric is processed by a double-sided circular knitting machine, and the middle layer of the fabric is passed through the intersecting tuck of the dial and the needle cylinder to connect the structure of the inner and outer layers of the fabric; the outer layer of the fabric is fully looped through the needle cylinder It is processed, and the inner layer is processed by the needle disc full circle process.

[0023] 3) Shaping: temperature 150°C, overfeed 25%, vehicle speed 25m / min.

[0024] 4) Pre-treat the fabric after the previous step with a bath ratio of 1:10, the additives are: defoamer 0.06-1.5g / L, dispersant 1-4g / L, penetrant 1-4g / L, hydrogen peroxide stabilizer 0.3~3g / L.

[0025] 5) Dyeing: Two-bath method is used for dyeing in THEN air-flo...

Embodiment 2

[0029] 1) Selection of raw materials: 18tex pure cotton combed yarn is selected for the outer layer of the fabric; polyester fiber filament is selected for the inner layer, and its single fineness is 70D.

[0030] 2) Machine knitting: the fabric is processed by a double-sided circular knitting machine, and the middle layer of the fabric is processed through the complete loop of the dial and the needle cylinder to connect the inner and outer layer structures of the fabric; the outer layer of the fabric is fully looped through the needle cylinder. It is processed, and the inner layer is processed by the needle disc full circle process.

Abstract

The invention relates to a three-dimensional warm-keeping knitted fabric and a preparation method thereof. The inner layer and the surface layer of the fabric are formed by weaving one or two of synthetic fiber filaments and staple fiber yarns and are in sleeved-connection through the synthetic fiber filaments to form a middle layer. The preparation method comprises the steps that the fabric is formed by a double-face circular knitting machine; the middle layer of the fabric is connected with the inner layer structure and the outer layer structure of the fabric by a needle disk and needle barrel crossing doubling stitch or needle disk and needle barrel complete doubling stitch processing technology; the outer layer of the fabric is processed by a needle barrel complete circling technology, and the inner layer of the fabric is processed by a needle disk complete circling technology. The inner layer of the three-dimensional warm-keeping knitted fabric is lower in extensibility and is higher in heat resistance the good three-dimensional structure of the fabric is kept, so that the fabric is good in warm-keeping effect and high in balling resistance; the preparation technology is simple and low in cost and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of knitted fabrics, in particular to a three-dimensional warm-keeping knitted fabric and a preparation method thereof. Background technique [0002] With the improvement of living standards, people's requirements for dressing are getting higher and higher. Warm clothing has shifted from outerwear to underwear, from the traditional "warm, thick, heavy, and swollen" to "warm, thin, light, and healthy". From a single warm type to a comfortable, functional and healthy type. In the past, thermal underwear fabrics were generally implanted with short fibers for clothing on plastic films to form needle-punched non-woven fabrics, and then the clothing fabrics were bonded on both sides, and then cut and sewed to make thermal underwear or other thermal clothing. However, through actual use, it was found that thermal underwear products made of such fabrics have no elasticity, poor tear resistance, and are not close to the body a...
