Embodiment 1

[0033]Pure cotton plain weave: 1 upper and 1 lower pure cotton plain weave fabrics are subjected to densification and flattening processing on the front of the fabric through a tension-type segmental processing device; The enveloping angle of the tension of the fabric and the differential movement of the front and rear rollers are used to process the reverse side of the fabric with micro-looping and loosening; and then carry out the processing of the densification and flattening of the front of the fabric by the upward compression of the thermal tension auxiliary roller, and the effect is stable. Finally, the gradient structure fabric with tight front and loose back is led out by the rear guide roller. The temperature of the hot tension main roller and the hot tension auxiliary roller is adjusted to 120 °, and at the same time, the fabric passes through the liquid tank (surfactant is added in the liquid tank) to realize the hydrophilic finishing of the reverse side of the fabri...

Embodiment 3

[0039] Polyester-cotton (65 / 35) plain weave fabric: 1 upper and 1 lower polyester-cotton fabrics are subjected to densification and flattening processing on the front of the fabric through a tension type segmental processing device; The front and rear rollers change the tension enveloping angle of the fabric and the differential movement of the front and rear rollers to perform micro-pile and loosening processing on the reverse side of the fabric; Stable processing, finally, the gradient structure fabric with tight front side and loose back side is led out by the rear guide roller. The temperature of the hot tension main roller and the hot tension auxiliary roller is adjusted to 160 °, and at the same time, the fabric passes through the liquid tank (surfactant is added in the liquid tank) to realize the hydrophilic finishing of the reverse side of the fabric.

Abstract

The invention relates to a preparation method and an application of a segmented tension dense and loose gradient structure fabric. The preparation method includes the steps: firstly, compressing the front surface of the fabric upwards by a thermal tension main roller to perform densifying and leveling; secondly, changing the tension wrap angle and differential motion of the fabric by lower front and back double rollers through 2-8 groups of segmented tension mechanisms to process loose micro-fluffing loops on the back surface of the fabric; thirdly, compressing the front surface of the fabricupwards by a thermal tension roller shaft to perform densifying and leveling with stable effects; finally, leading out the gradient structure fabric with the dense front surface and the loose back surface by a guide roller. The preparation method can be used for forming woven fabrics and knitted fabrics with gradient structures and two-sided structures, and the gradient structure fabric can be used for textiles for water repellence, sweat removal, filtration and the like.

Description

technical field [0001] The invention relates to a preparation method of a segmented tension type dense and loose gradient structure fabric, the method and the use of the fabric obtained by the method. Background technique [0002] In recent years, research on gradient structure theory and product design has been reported. However, most of the previous studies focused on knitted fabrics, and there were few reports on woven fabrics. Functional fabrics with gradient structure are developed on the basis of improving the thermal comfort of fabrics. The fabric with double-sided structure is constructed so that the inner side of the fabric has a certain moisture-wicking and sweat-wicking function, and the outer side of the fabric has good water repellency, thereby forming a double-sided structured fabric with different hydrophilic and hydrophobic properties on both sides. Use the isolation effect of the water-repellent part to keep the external water away from the fabric to achie...
