Description

Technical Field

[0001] The invention relates to the technical field of textile industry, in particular to a double-layer unilateral moisture-conducting webbing with two-level differential capillary effect and a manufacturing method thereof. Background Art

[0002] At present, the webbings circulating in the domestic and foreign markets are generally ordinary flat webbings without special functions. When used in sports and fitness, especially when in contact with the human body and the human body sweats a lot, they do not have good heat and moisture conduction functions and dry slowly, which seriously affects the comfort of the human body, causing a wet sticking effect, affecting the functionality and performance of the human body.

[0003] There are also some thin first-level differential capillary effect unidirectional moisture conduction functional webbings with relatively thin thickness (generally less than 0.8mm). In the water drop test, the liquid water can be conducted and diffused from the inner layer of the webbing to the outer layer of the webbing within 60s, keeping the inner layer of the webbing dry and improving the thermal and moisture comfort of the webbing.

[0004] However, for webbings with a thickness of 0.9 mm or more, the use of first-level differential capillary effect unidirectional moisture conduction fabrics will increase the thickness of the webbing, and the diffusion (non-directional flow) time of liquid water from the inner layer of the webbing to the outer layer of the webbing will be prolonged. The first-level differential capillary effect unidirectional moisture conduction function will be used, and the unidirectional moisture conduction function of the webbing will be weakened. The time for liquid water to be conducted and diffused from the inner layer of the webbing to the outer layer of the webbing exceeds 60s, the speed slows down, the drying of the inner layer of the webbing slows down, and the thermal and moisture comfort of the webbing is weakened. Summary of the invention

[0052] The above technical solution of the present invention has at least the following beneficial effects compared with the prior art:

[0053] The present invention provides a double-layer unidirectional moisture-conducting webbing with two-level differential capillary effect and a manufacturing method thereof. The webbing has an upper fabric and a lower fabric woven in the thickness direction. The upper fabric upper surface of the upper fabric forms a first front warp floating point; the upper fabric lower surface of the upper fabric forms a first back warp floating point; the lower fabric upper surface of the lower fabric forms a second front warp floating point; and the lower fabric lower surface of the lower fabric forms a second back warp floating point. The single fiber line density of the second back warp floating point is greater than the single fiber line density of the second front warp floating point, so that a first-level differential capillary effect is formed between the lower fabric lower surface of the lower fabric and the upper surface of the lower fabric. The second front warp floating point and the first back warp floating point are close to each other, and the single fiber line density of the second front warp floating point is equal to the single fiber line density of the first back warp floating point, so that a hollow dialysis layer is formed between the upper surface of the lower fabric and the lower surface of the upper fabric. The single fiber line density of the first reverse warp floating point is greater than the single fiber line density of the first front warp floating point, so that a secondary differential capillary effect is formed between the lower surface of the upper fabric and the upper surface of the upper fabric.

[0054] The present invention provides a double-layer unidirectional moisture-conducting webbing with two-level differential capillary effect and a manufacturing method thereof. When a human body sweats, liquid water (sweat) on the lower surface of the lower fabric of the lower fabric (inner layer of the webbing) is quickly conducted and diffused to the hollow dialysis layer between the upper surface of the lower fabric and the lower surface of the upper fabric by relying on the first-level differential capillary effect. Then, on the lower surface of the upper fabric, liquid water (sweat) is quickly conducted and diffused to the upper surface of the upper fabric (outer layer of the webbing) by relying on the second-level differential capillary effect. The diffusion time of liquid water (sweat) from the lower surface of the lower fabric of the lower fabric (inner layer of the webbing) to the upper surface of the upper fabric of the upper fabric (outer layer of the webbing) is reduced, the lower surface of the lower fabric of the lower fabric (inner layer of the webbing) of the lower fabric dries quickly, and the thermal and humid comfort of the webbing is enhanced.

[0055] The present invention provides a double-layer one-way moisture-conducting webbing with a two-stage differential capillary effect and a manufacturing method thereof. The webbing adopts a two-stage differential capillary effect to perform double-layer one-way moisture-conducting, and quickly conducts and diffuses liquid water (sweat) through a hollow dialysis layer, thereby reducing the diffusion time of liquid water (sweat) from the lower surface of the lower fabric of the lower fabric (inner layer of the webbing) to the upper surface of the upper fabric of the upper fabric (outer layer of the webbing), the lower surface of the lower fabric of the lower fabric (inner layer of the webbing) dries quickly, and the thermal and hygroscopic comfort of the webbing is enhanced.

[0056] The present invention provides a double-layer unidirectional moisture-conducting webbing with two-level differential capillary effect and a manufacturing method thereof. The hollow dialysis layer accelerates the speed of liquid water (sweat) being conducted and spread from the upper surface of a lower fabric to the lower surface of an upper fabric, reduces the diffusion time of liquid water (sweat) from the lower surface of the lower fabric of the lower fabric (inner layer of the webbing) to the upper surface of the upper fabric of the upper fabric (outer layer of the webbing), the lower surface of the lower fabric of the lower fabric (inner layer of the webbing) dries quickly, and the thermal and humid comfort of the webbing is enhanced.

[0057] The present invention provides a double-layer unidirectional moisture-conducting webbing with two-level differential capillary effect and a manufacturing method thereof. When the webbing is used to contact a human body fastener or reinforcement or a backpack strap, the human body sweats, and the inner layer of the webbing relies on the first-level differential capillary effect to quickly conduct and diffuse the sweat to the hollow dialysis layer of the fabric, and then utilizes the second-level differential capillary effect to quickly conduct and diffuse the sweat from the hollow dialysis layer to the outer layer of the webbing, thereby reducing the flow time of liquid water in the inner and outer layers of the webbing. According to a water dripping test, the drying time of the inner layer of the webbing is ≤30s, the inner layer of the webbing dries quickly, and has good thermal and hygroscopic comfort. The webbing can be widely used as a fastener or reinforcement or backpack strap for clothing, shoes and hats used in sports, heavy physical labor and working in a high-temperature environment.

[0058] The present invention provides a double-layer unidirectional moisture-conducting webbing with two-level differential capillary effect and a manufacturing method thereof. In a fabric circulation area, a connecting warp yarn is used to weave a connecting line with an upper weft yarn and a lower weft yarn, and a third front warp floating point is formed only on the upper surface of the upper fabric of the upper fabric (the outer layer of the webbing), and a third reverse warp floating point is formed on the lower surface of the lower fabric of the lower fabric (the inner layer of the webbing), and there are no weft floating points on the outer layer and the inner layer of the webbing. A dense concave strip is easily formed along the width direction at the connection between the upper fabric and the lower fabric, so that the surface of the webbing is flat and uniform, and there is no difference in appearance. The webbing can be widely used as a fastener or reinforcement for clothing, shoes and hats or a backpack strap for sports, strong physical labor and work in a high-temperature environment.

[0103] Furthermore, the single fiber linear density of warp yarn No. 1 and warp yarn No. 5 is 3D (3 denier), the single fiber linear density of warp yarn No. 3 and warp yarn No. 7 is 2D (2 denier); the single fiber linear density of warp yarn No. 4 and warp yarn No. 8 is 2D (2 denier), and the single fiber linear density of warp yarn No. 2 and warp yarn No. 6 is 1D (1 denier).

[0104] Furthermore, the first warp yarn and the fifth warp yarn are made of polyester filaments of 150D / 48-52f-150D / 48-52f×2.

[0105] Warp yarn No. 3 and No. 7 use polyester filaments of 150D / 70-78f-150D / 70-78f×2;

[0106] The 4th and 8th warp yarns are made of 150D / 70-78f-150D / 70-78f×2 polyester filaments;

[0107] The No. 2 warp yarn and the No. 6 warp yarn are made of polyester filaments of 150D / 136-164f-150D / 136-164f×2.

[0108] The single fiber linear density of the upper weft yarn S (weft yarn No. Ⅰ, weft yarn No. Ⅱ, weft yarn No. Ⅲ and weft yarn No. Ⅳ) is 1D (1 denier), and the single fiber linear density of the lower weft yarn X (weft yarn No. Ⅰ', weft yarn No. Ⅱ', weft yarn No. Ⅲ' and weft yarn No. Ⅳ) is 3D (3 denier).

[0109] Furthermore, the upper weft yarn S is made of 150D / 136-164f-150D / 136-164f×2 polyester filaments; and the lower weft yarn X is made of 150D / 48-52f-150D / 48-52f×2 polyester filaments.

[0110] The single fiber linear density of warp yarn No. 1 and warp yarn No. 5 of the present invention is greater than the single fiber linear density of warp yarn No. 3 and warp yarn No. 7, so that the single fiber linear density of the second reverse warp floating point J2' across 3 wefts formed on the lower surface N2 of the upper fabric of the lower fabric 200 is greater than the single fiber linear density of the second front warp floating point J1' across 3 wefts formed on the upper surface M2 of the lower fabric 200, so that a first-order differential capillary effect is formed between the lower surface N2 of the lower fabric 200 and the lower surface M2 of the lower fabric.

[0111] The single fiber linear density of warp yarn No. 3 and warp yarn No. 7 of the present invention is equal to the single fiber linear density of warp yarn No. 4 and warp yarn No. 8, so that the single fiber linear density of the second front warp floating point J1' across 3 wefts formed on the upper surface M2 of the lower fabric 200 is equal to the single fiber linear density of the first back warp floating point J2 across 3 wefts formed on the lower surface N1 of the upper fabric 100, and the warp yarn No. 3 is adjacent to the warp yarn No. 4, and the warp yarn No. 7 is adjacent to the warp yarn No. 8, so that the second front warp floating point J1' and the first back warp floating point J2 are close to each other, so that a hollow seepage layer is formed between the upper surface M2 of the lower fabric and the lower surface N1 of the upper fabric.

[0112] The single fiber linear density of the No. 4 warp yarn and the No. 8 warp yarn of the present invention is greater than the single fiber linear density of the No. 2 warp yarn and the No. 6 warp yarn, so that the single fiber linear density of the first reverse warp floating point J2 spanning 3 wefts formed by the upper fabric lower surface N1 of the upper fabric 100 is greater than the first front warp floating point J1 spanning 3 wefts formed by the upper fabric upper surface M1 of the upper fabric 100, and a secondary differential capillary effect is formed between the upper fabric lower surface N1 of the upper fabric 100 and the upper fabric upper surface M1.

[0113] In the present invention, when a human body sweats, on the lower surface N2 (inner layer of the webbing) of the lower fabric 200, liquid water (sweat) is quickly conducted and diffused to the hollow dialysis layer between the upper surface M2 of the lower fabric and the lower surface N1 of the upper fabric by means of a first-order differential capillary effect. The hollow dialysis layer accelerates the speed at which liquid water (sweat) is conducted and diffused from the upper surface M2 of the lower fabric to the lower surface N1 of the upper fabric, so that the liquid water (sweat) is quickly conducted and diffused to the lower surface N1 of the upper fabric. Afterwards, on the lower surface N1 of the upper fabric, liquid water (sweat) relies on the secondary differential capillary effect to quickly conduct and diffuse to the upper surface M1 of the upper fabric (outer layer of the webbing), thereby reducing the diffusion time of the liquid water (sweat) from the lower surface N2 (inner layer of the webbing) of the lower fabric 200 to the upper surface M1 (outer layer of the webbing) of the upper fabric 100. The lower surface N2 (inner layer of the webbing) of the lower fabric 200 dries quickly, and the thermal and moisture comfort of the webbing is enhanced.

[0114] Combination Figure 2 and Figure 7 According to an embodiment of the present invention, each fabric circulation area Q uses 1 connecting warp yarn L to weave a connecting thread F with the upper weft yarn S and the lower weft yarn X.

[0117] The connecting warp yarn L is woven with the upper weft yarn S and the lower weft yarn X to form a connecting line F, such as Figure 2 and Figure 7 shown.

[0118] The present invention uses one connecting warp yarn L and the upper weft yarn S and the lower weft yarn X to weave a connecting line F in a fabric circulation area Q, and only forms a third front warp floating point J3 on the upper fabric upper surface M1 (ribbon outer layer) of the upper fabric 100, and forms a third reverse warp floating point J4 on the lower fabric lower surface N2 (ribbon inner layer) of the lower fabric 200. There are no weft floating points on the upper fabric upper surface M1 (ribbon outer layer) of the upper fabric 100 and the lower fabric lower surface N2 (ribbon inner layer) of the lower fabric 200. It is easy to form dense concave strips along the width direction at the connection between the upper fabric 100 and the lower fabric 200, so that the surface of the ribbon is flat and uniform, and there is no difference in appearance compared with a single-layer moisture-conducting ribbon.

[0119] Furthermore, the connecting warp yarn L is made of polyester filaments of 150D / 70-78f-150D / 70-78f×2.
