Embodiment 1

[0042] Pure cotton plain weave fabric: 1 upper and 1 lower plain weave fabric can be densified on the front side and loosened on the reverse side through 3 sets of suction and heat pressing mechanism, feeding smooth fabric guide roller and outputting the output of the fabric with gradient structure in the thickness direction The composition of the roller; the suction rate of the suction hole is 10ml / s. The heating bar temperature was adjusted to 100°C. Spray the wet mist, and spray water vapor to the reverse side of the fabric every 2S.

[0043] Experiment: When the fabric absorbs 50% of its own weight, that is, when the moisture regain rate is 50%, the inner side is still dry and comfortable to wear; the outer side is colored in 2.1 sec, which shows that its one-way moisture transfer is fast. Therefore, it is proved It is effective and practical to adjust the tightness gradient of the fabric with a simple device, and the obtained fabric has a high-efficiency one-way perspira...

Embodiment 2

[0045] Pure cotton twill fabric: 2 upper and 1 lower plain weave fabrics can be densified on the front side and loosened on the reverse side by 3 sets of plain weave fabrics, the suction and heat press mechanism for feeding flattened fabrics and the output of fabrics with a gradient structure in the thickness direction The composition of the roller; the suction rate of the suction hole is 10ml / s. The heating bar temperature was adjusted to 100°C. Spray the wet mist, and spray water vapor to the reverse side of the fabric every 2S.

[0046] Experiment: When the fabric absorbs 50% of its own weight, that is, when the moisture regain rate is 50%, the inner side is still dry and comfortable to wear; the outer side is colored in 1.9sec, which shows that its one-way moisture transfer is fast. Therefore, it is proved It is effective and practical to adjust the tightness gradient of the fabric with a simple device, and the obtained fabric has a high-efficiency one-way perspiration fu...

Embodiment 3

[0048] Polyester-cotton (65 / 35) plain weave fabric: 1 up and 1 down plain weave fabric can be densified on the front side and loosened on the back side through 3 sets of suction and heat pressing mechanism, feeding smooth fabric guide roller and output thickness direction The output roll of the gradient structure fabric is composed; the suction rate of the suction hole is 10ml / s. The heating bar temperature was adjusted to 110°C. Spray the wet mist, and spray water vapor to the reverse side of the fabric every 2S.

[0049] Experiment: When the fabric absorbs 50% of its own weight, that is, when the moisture regain rate is 50%, the inner side is still dry and comfortable to wear; the outer side is colored in 1.8 sec, which shows that its one-way moisture transfer is fast. Therefore, it is proved It is effective and practical to adjust the tightness gradient of the fabric with a simple device, and the obtained fabric has a high-efficiency one-way perspiration function.

Abstract

The invention relates to a suction type preparation device and method for fabric with gradient change of elasticity in thickness direction. The preparation device comprises multiple groups of loosening rollers and suction hot-pressing mechanisms for key gradient-structured fabric with one dense side and the other loosening side. The preparation method Of the fabric with the gradient structure based on the device comprises the following steps: the fabric is fed flatly by fabric guide rollers, the reverse side of the warp-wound fabric is loosened by front loosening rollers under the differentialaction, the fabric then enters suction hot-pressing heads for gradient suction and hot pressing shaping on the front side, the reverse side of the fabric is loosened reversely by rear loosening rollers under the differential action on the reverse side, and unidirectional loosening densification processing is completed; then, loosening densification is performed on two sides of the fabric from thesecond stage to the eight stage under the action of the following 1 to 7 groups of the same suction hot-pressing mechanisms, so that the fabric with the gradient elasticity structure is formed. The fabric can be used for forming woven fabric and knitted fabric with the gradient structure and / or double-sided structure, and the obtained fabric can be applied to water repellence and perspiration textile, filtering textile and the like.

Description

technical field [0001] The invention relates to a preparation device for suction gradient change of fabric thickness direction, a preparation method using the preparation device, and the application of the fabric and the preparation method. Background technique [0002] In recent years, there have been reports on the research on the preparation device and production process of the gradient structure. However, most of the previous studies focused on the reports on the production process, and there were few reports on the preparation devices with gradient changes in the structure. Functional fabric with gradient structure is developed on the basis of improving the comfort of fabrics in heat and humidity. 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, thus forming a double-sided hydrophilic and hydrophobic fabric.
