Embodiment 1

[0050] A preparation method for a cashmere fabric with a high heat-retaining air layer, comprising the following steps:

[0051] Step S1: weaving, such as figure 1 As shown, the knitting method of upper and lower double dials is adopted, six-way knitting, in which the low-heel needles of the first way are fed with wool / cashmere blended yarn, and the low-heel needles of the second way are fed with wool / nylon blended yarn , The high-heel needles of the lower dial in the third way are fed with wool / cashmere blended yarn, the high-heel needles of the fourth way are fed with wool / nylon blended yarn, and the low-heel needles of the fifth way are all fed with wool / cashmere Cashmere blended yarn, wool / cashmere blended yarn is fed to the high-heel needles of the upper and lower dials on the 6th road, and hollow polyester filaments 7 are introduced between the front and back stitch courses of the 1st to 4th roads by inserting wefts to obtain gray cloth.

[0052] Step S2: shake the gra...

Embodiment 2

[0060] A preparation method for a cashmere fabric with a high heat-retaining air layer, comprising the following steps:

[0061] Step S1: weaving, such as figure 1 As shown, the knitting method of upper and lower double dials is adopted, and six knitting methods are used, in which the low-heel needles of the lower dial are fed with cashmere yarn in the first pass, wool / nylon blended yarn is fed with the low-heel needles of the second pass, and the third pass is knitting. The high-heel needles of the lower dial are fed with cashmere yarn, the high-heel needles of the fourth road are fed with wool / nylon blended yarn, the low-heel needles of the upper and lower dials of the fifth road are all fed with cashmere blended yarn, and the upper and lower needles of the sixth road All the pan-heel needles are fed with cashmere yarn, and hollow polyester DTY filaments 7 are introduced between the front and back courses of the 1st to 4th courses by weft insertion to obtain gray fabrics.

Embodiment 3

[0070] A preparation method for a cashmere fabric with a high heat-retaining air layer, comprising the following steps:

[0071] Step S1: weaving, such as figure 1 As shown, the method of knitting with upper and lower double dials is adopted, and six knitting methods are used, in which the low-heel needles of the first way are fed with cashmere yarn, the low-heel needles of the second way are fed with cashmere yarn, and the lower needles of the third way are high Feed cashmere yarn to the heel needles, cashmere yarn to the high heel needles on the 4th road, cashmere yarn to all the low heel needles on the 5th road, and cashmere yarn to all the high heel needles on the 6th road. The hollow acrylic filaments 7 are introduced between the front and back courses of the 1st to 4th courses by weft insertion to obtain a gray cloth.

[0072] Step S2: shake the pellets, use the shaker to process the rough cloth, the processing temperature is 45°C, and the processing time is 15 minutes....

Abstract

The invention relates to the field of textile and apparel, in particular to a high-heat preservation air-layer wool fabric. The wool fabric is selected for knitting, six-way knitting in a double-needle disc coiling mode with upper and lower needle discs is adopted, the air layer is formed in the middle of the fabric, hollow polyester yarn is introduced at the same time in the air layer, while theair storage capacity is greatly improved, the air is made to be still in the fabric, air convection is weakened, the heat preservation of the fabric is enhanced obviously, and the heat preservation iscomparable to that of a down product. The invention also provides a preparation method for the above fabric. A loom-state fabric is firstly subjected to polar fleece processing before a fulling process, a mode of primary fulling, singeing and secondary fulling is adopted, the wool feel is more uniform, plump and compact, shearing is carried out after further heat setting, the wool feel on the front is short and dense, the wool feel on the back is relatively thick, and while the heat preservation is ensured, the fabric style and the hand feel are both excellent.

Description

technical field [0001] The invention relates to the field of textiles and garments, in particular to a preparation process of a novel air-layer woolen fabric with high heat retention. Background technique [0002] Wool knitted coats have always been favored by consumers for their high quality. However, compared with down jackets, the warmth retention of wool knitted fabrics is still insufficient, which makes wool knitted garments have certain limitations in the wearing cycle and sales market in winter. limitations. Still air is a poor conductor of heat, and the more still air there is in a fabric, the better the fabric will retain heat. Based on this, two aspects can be considered to improve the warmth retention of the fabric. On the one hand, it is to create as much air volume as possible for the fabric, and on the other hand, it is to ensure the stillness of the air as much as possible to reduce air convection. Only a sufficient amount of still air can ensure the warmth ...
