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 preparation device and method for suction gradient change of fabric thickness direction. The preparation device is a preparation device for fabrics with a dense gradient on one side and a loose gradient structure on the other side, which consists of multiple sets of key suction and heat pressing mechanisms including loose rollers. The preparation method of the gradient structure fabric using this device is that the fabric is fed flat by the cloth guide roller, and the front loosening roller loosens the reverse side of the warped fabric under the differential action, and then enters the suction heat head for gradient suction on the front side of the fabric. and hot pressing to set the shape, and then the rear loosening roller loosens the reverse side of the fabric under the action of the reverse side difference to complete the one-way loosening and densification process, and then under the action of the subsequent 1 to 7 groups of the same suction and hot pressing mechanism, carry out the second The loosening and densification process on both sides of the fabric from the second to the eighth level to form a fabric with a gradient structure of elasticity. The fabric can be used for forming and processing of woven fabrics and knitted fabrics with gradient structure and / or double-sided structure, and the obtained fabric can be used for textiles such as water-repellent perspiration and filtration.

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. Tw...
