Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric technology, and more specifically, to an elastic fabric. Background Technology
[0002] Elastic fabric is a common type of clothing fabric that can stretch and recover with the range of motion of people, reducing the risk of the internal fibers breaking due to tension during the stretching process.
[0003] When clothing made of elastic fabrics is used outdoors, external liquids come into contact with the fabric. Some waterproof fabrics are not treated to be waterproof. When external liquids come into direct contact with the fabric, the liquids can pass directly through the fabric and come into contact with the skin, affecting the comfort of the fabric during use. Therefore, a structure is designed to solve the problem of poor waterproof performance of some elastic fabrics. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an elastic fabric that improves the overall waterproof performance of the fabric through structural design.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an elastic fabric includes a base layer, one side of which is recessed to form a waterproof groove and the other side has a raised strip. The waterproofness of the inner wall of the waterproof groove is greater than that of the rest of the base layer. Several absorbent strips are fixedly connected to the base layer, and the absorbent strips abut against the side wall of the raised strip along its length. Several waterproof coatings are fixedly connected to the side of the base layer forming the waterproof groove, and the waterproof coatings are offset from the waterproof groove.
[0006] The present invention is further configured such that: the cross-sectional shape of the waterproof groove and the protrusion is arc-shaped, the relative positions of the waterproof groove and the protrusion are the same, and the waterproof groove is formed by hot pressing.
[0007] The present invention is further configured such that the weaving density of the absorbent strip is less than the weaving density of the base layer, and the absorbent strip is woven from moisture-absorbing yarn.
[0008] The present invention is further configured such that: the moisture-absorbing yarn includes a core yarn one and a core yarn two, the core yarn one being formed by twisting ramie fibers, and the core yarn two being formed by twisting polyester fibers one.
[0009] The present invention is further configured such that: the base layer is woven from elastic yarn, the elastic yarn includes a core yarn and a covering yarn, the core yarn is formed by twisting spandex fibers, and the covering yarn is formed by twisting polyester fibers twice.
[0010] The present invention is further configured such that the waterproof coating is a polyurethane coating.
[0011] In summary, this utility model has the following beneficial effects: the waterproof groove and convex strip formed by hot pressing melt some of the fibers inside the base layer and seal the pores inside the fabric, reducing the possibility of external liquids passing through the pores inside the fabric. The setting of the water-absorbing strip position can stably absorb the water that comes into contact with the base layer along the outer peripheral wall of the convex strip, further reducing the amount of external liquids passing through the base layer and ensuring the waterproof effect of the fabric.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] This type of elastic fabric, such as Figure 1 and Figure 2 As shown, the material includes a base layer 1. One side of the base layer 1 is recessed to form a waterproof groove 2, and the other side has a raised strip 3. The waterproof groove 2 is formed on one side of the base layer 1 by hot pressing, and the raised strip 3 is formed on the other side of the base layer 1. The hot press head of the hot press is set to be arc-shaped, and the open end of the hot press head is away from the worktable. The hot press table of the hot press is set to be an arc-shaped plate that cooperates with the hot press head. Therefore, the cross-sectional shape of the waterproof groove 2 and the raised strip 3 formed by hot pressing is arc-shaped. The waterproof groove 2 formed by hot pressing melts the fibers inside the base layer 1 and seals the pores inside the fabric. Therefore, the waterproofness of the inner wall of the waterproof groove 2 is greater than that of the rest of the base layer 1, which reduces the liquid that passes through the waterproof groove 2 and comes into contact with the body surface, thus ensuring the waterproof effect of the fabric.
[0019] like Figure 1As shown, several absorbent strips 4 are sewn onto the base layer 1 by a sewing machine. The absorbent strips 4 abut against the side wall of the protruding strip 3 along its length. Since the outer peripheral wall of the protruding strip 3 is arc-shaped and the surface of the absorbent strip 4 is relatively smooth after hot pressing, when external liquid comes into contact with the protruding strip 3, the liquid will slide down along the outer peripheral wall of the protruding strip 3 under its own gravity and be absorbed by the absorbent strip 4. By setting the position of the absorbent strip 4, it can receive the liquid dripping along the protruding strip 3 as soon as possible, reducing the amount of external liquid absorbed by the base layer 1.
[0020] like Figure 1 and Figure 3 As shown, the weaving density of the absorbent strip 4 is less than that of the base layer 1, thus increasing the space inside the absorbent strip 4 for liquid retention and improving its absorbency. The absorbent strip 4 is woven from moisture-absorbing yarn 6, which includes core yarn 1 7 and core yarn 2 8. Core yarn 1 7 and core yarn 2 8 are twisted together by a twisting machine to form the moisture-absorbing yarn 6. Core yarn 1 7 is made of ramie fiber and is twisted by a twisting machine. Ramie fiber has the characteristics of good moisture absorption and fast moisture dissipation. The use of ramie fiber improves the quick-drying efficiency of the absorbent strip 4. Core yarn 2 8 is made of polyester fiber 1 and has good structural strength and elasticity. The characteristics of polyester fiber 1 ensure its durability while allowing the structure to deform along with the base layer 1.
[0021] like Figure 1 and Figure 2 As shown, the base layer 1 forms a waterproof groove 2 on one side with several waterproof coatings 5 applied by a coating machine. The waterproof coatings 5 are offset from the waterproof groove 2. The waterproof coatings 5 are polyurethane coatings. The setting of the waterproof coatings 5 will hinder the airflow and exchange between the two sides of the fabric. However, by setting the position of the waterproof coatings 5, there is always a channel for outside air to flow between the inner wall of the waterproof groove 2 and the body surface, so that the fabric can take into account both waterproofness and breathability.
[0022] like Figure 1 and Figure 4 As shown, the base layer 1 is woven from elastic yarn 9, which includes a core yarn 10 and a covering yarn 11. The core yarn 10 and the covering yarn 11 are processed by a spinning process to form the elastic yarn 9. The core yarn 10 is made of spandex fiber by twisting it with a twisting machine. The good elasticity of spandex fiber is used to ensure that the fabric can rebound stably when subjected to tension. The covering yarn 11 is made of polyester fiber by twisting it with a twisting machine.
[0023] like Figures 1-4As shown, when the fabric needs to be made, elastic yarn 9 is put into the loom to weave into a base layer 1. A number of waterproof grooves 2 and raised strips 3 are formed by hot pressing along one side of the base layer 1. Then, polyurethane coating is applied to one side of the base layer 1 to form waterproof grooves 2 to form a number of waterproof coatings 5. Moisture-absorbing yarn 6 is put into the loom to weave into a water-absorbing layer. A number of water-absorbing strips 4 are cut along the thickness direction of the water-absorbing layer by a laser cutting machine. Finally, the water-absorbing strips 4 are sewn onto the base layer 1 by a sewing machine.
[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.
