TECHNICAL FIELD

[0001] The utility model relates to the technical field of textile fabric, more specifically, it relates to a waterproof and moisture permeable four-way stretch composite cloth. BACKGROUND

[0002] Four-way stretch composite cloth is a kind of fabric with excellent elasticity, mostly composed of polyester and spandex, commonly used in the manufacture of textiles such as clothing and sofa covers.

[0003] By coating the four-way stretch fabric with a waterproof coating to form a four-way stretch composite cloth with waterproof effect, it is commonly used in the manufacture of sofa covers and clothing, which has a certain waterproof effect. However, when used in clothing production, although the waterproof coating can provide some waterproof effect, its breathability is generally poor, and the sweat excreted by the human body can easily come into contact with the fabric and wet the fabric, causing the fabric to stick to the skin and affect the wearing comfort.

[0004] Therefore, a new solution is needed to solve this problem. UTILITY MODEL CONTENT

[0005] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a waterproof and moisture permeable four-way stretch composite cloth to improve the overall anti-sticking property and wearing comfort of the fabric.

[0006] The above technical purpose of the utility model is achieved by the following technical scheme: a waterproof and moisture permeable four-way stretch composite cloth, comprising a base layer, a plurality of drainage anti-sticking elements are fixedly connected to one side of the base layer, the plurality of drainage anti-sticking elements make the one side of the base layer uneven, the cross section of the drainage anti-sticking element is in the shape of a water droplet, the surface of the base layer with the plurality of drainage anti-sticking elements is covered with a waterproof and breathable film one, the other side of the base layer is covered with a waterproof and breathable film two, the waterproof and breathable film one is in contact with the drainage anti-sticking element, and a plurality of protrusions are formed on the surface of the waterproof and breathable film one.

[0007] The utility model is further provided as follows: the structure of the drainage anti-sticking element is the shape formed by cutting the water droplet structure in the vertical direction, one side of the drainage anti-sticking element is curved, and the other side is flat, and one end of the flat surface of the drainage anti-sticking element is in contact with the end surface of the base layer.

[0008] The utility model is further provided as follows: a plurality of drainage anti-sticking elements are arranged in a matrix array on the base layer, and the plurality of drainage anti-sticking elements are formed by a silica gel embossing machine.

[0009] The utility model is further provided as follows: the fabric organization of the base layer is set as satin weave, and the yarn used for weaving the base layer is set as high-elastic breathable yarn.

[0010] The present invention is further configured such that: the high-elasticity breathable yarn is a core-spun yarn, the core of the core-spun yarn is formed by twisting several spandex fibers, and the outer yarn of the core-spun yarn is formed by twisting several polyester profiled fibers, the cross section of the polyester profiled fibers is set to cross shape.

[0011] The present invention is further configured such that: the second waterproof and breathable membrane is fixedly connected to the base layer by an adhesive bonding method, and the first waterproof and breathable membrane is fixedly connected to the base layer by a coating method.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A waterproof and breathable four-way stretch composite fabric, such as Figure 1As shown, the fabric includes a base layer 1. Several anti-slip elements 5 are fixedly connected to one end face of the base layer 1, making one end face of the base layer 1 uneven. The cross-section of each anti-slip element 5 is teardrop-shaped. A waterproof and breathable membrane 2 covers the end face of the base layer 1 with the anti-slip elements 5, and a second waterproof and breathable membrane 3 covers the other end face of the base layer 1. The second waterproof and breathable membrane 2 abuts against the anti-slip elements 5, forming several protrusions 4 on its surface. When this fabric is used in clothing manufacturing, the base layer 1 has several anti-slip elements... One side of the anti-adhesion patch 5 is placed close to the human body. When the ambient temperature is low, the warm air generated by the outside air entering the clothing and the human body produces water vapor, which condenses into water droplets and adheres to the surface of the waterproof and breathable membrane 2. The part of the waterproof and breathable membrane 2 that abuts against several anti-adhesion patches 5 on the base layer 1 forms a protrusion 4. While reducing the contact area between the fabric and the skin, it can also guide the water droplets on the waterproof and breathable membrane 2 to slide off, reduce the residue of water droplets on the waterproof and breathable membrane 2, and reduce the possibility of the waterproof and breathable membrane 2 sticking to the human body or inner layer.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the base layer 1 is woven from high-elasticity breathable yarn 6, which is a core-spun yarn. The core 7 of the core-spun yarn is formed by twisting several spandex fibers using a twisting machine. The outer covering yarn 8 of the core-spun yarn is formed by twisting several polyester profiled fibers using a twisting machine. The core 7 and the outer covering yarn 8 are fed into a spinning machine. Through the spinning process, the outer covering yarn 8 is spirally wrapped around the outside of the core 7 to obtain the high-elasticity breathable yarn 6. The cross-section of the polyester profiled fibers is set to a cross shape. The cross-shaped cross-section can increase the grooves on the surface of the polyester profiled fibers, making them fluffy and breathable. The core 7, which is formed by twisting spandex fibers, gives the high-elasticity breathable yarn good elasticity. The structure of the base layer 1 is set as a satin weave. Satin weave has better elasticity and breathability than plain weave and twill weave. The high-elasticity breathable yarn 6 is fed into an air-jet loom and the base layer 1 is woven according to the structure sequence of the satin weave.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, after obtaining the base layer 1, a silicone rubber material is heated and extruded on the base layer 1 using an embossing machine to form several anti-adhesion components 5. The structure of the anti-adhesion component 5 is the shape formed by cutting a water droplet structure vertically, that is, half of the water droplet structure. One side of the anti-adhesion component 5 is an irregular curved surface, and the other side is a flat surface. One end of its flat surface is fixedly connected to the base layer 1. Before using the embossing machine, glue is first applied to the end face of the base layer 1 by a coating machine to ensure the connection strength between the anti-adhesion component 5 and the base layer 1. Preferably, the several anti-adhesion components 5 are arranged in a matrix array on the base layer 1, so that the anti-adhesion components 5 are evenly distributed on the base layer 1, ensuring the uniformity and integrity of the overall structure of the base layer 1.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the end face of the base layer 1 with several anti-adhesion components 5 is covered with a waterproof and breathable membrane 1 2, and the other end face is covered with a waterproof and breathable membrane 2 3. The waterproof and breathable membrane 2 3 is made of TPU material. TPU waterproof and breathable membrane has the characteristics of good elasticity, high strength, high moisture permeability, good processing performance and water resistance. It should be noted that the lamination of the waterproof and breathable membrane 2 3 is carried out before the embossing operation, that is, before the several anti-adhesion components 5 are formed. After the waterproof and breathable membrane 1 2 is laminated, the embossing operation is carried out, and finally the waterproof and breathable membrane 1 2 is laminated. The waterproof and breathable membrane 2 3 is fixedly connected to the base layer 1 by the lamination method, and the waterproof and breathable membrane 1 2 is fixedly connected to the base layer 1 by the coating method. The waterproof and breathable membrane 1 2 is made of PU material. The waterproof and breathable membrane 2 3 and the base layer 1 are placed together in a hot press. Through heating and pressurization, the waterproof and breathable membrane 2 3 and the base layer 1 are tightly bonded together. Then the embossing operation is carried out. Finally, the prepared coating agent is directly applied. The coating is applied to the surface of the base layer 1, which has several anti-adhesion elements 5. After drying and curing, the coating is tightly bonded to the base layer 1 to form a waterproof and breathable membrane 2. The waterproof and breathable membrane 2 and the anti-adhesion elements 5 abut against each other on the surface of the waterproof and breathable membrane 2 to form several protrusions 4 with the same shape as the anti-adhesion elements 5. As the layer that is in direct contact with the outside world, the waterproof and breathable membrane 3 can effectively prevent external liquids from wetting the base layer 1. The TPU material has good wear resistance. As the inner layer facing the human body, the waterproof and breathable membrane 2 can reduce the wetting of the base layer 1 by water droplets formed after the exchange of hot and cold air, so that the overall waterproof effect of the fabric is better. The protrusions 4 with the same shape as the anti-adhesion elements 5 can guide water droplets on the waterproof and breathable membrane 2 to fall off, reduce the water droplet residue on its surface, and reduce the adhesion of the waterproof and breathable membrane 2 to human skin or other substances caused by too much residual water droplets. At the same time, it reduces the contact area between the base layer 1 and the skin, and improves wearing comfort.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
