Description

Technical Field

[0001] This utility model relates to the field of fabrics, and more specifically, to an elastic fabric. Background Technology

[0002] Fabric refers to woven materials made from fibers through processes such as weaving, knitting, and non-woven fabrics.

[0003] Existing fabrics require a certain degree of elasticity in their application, especially for clothing that demands high elasticity, such as tight-fitting garments. Because the fabric fits tightly against the skin, it needs to stretch according to the wearer's movements. This is particularly true for tight-fitting garments, where the fabric undergoes frequent deformation during activity. Therefore, during the selection process, people conduct stretch tests on the fabric's elongation in one direction to ensure it meets their needs. However, if the fabric deforms excessively during unidirectional stretching, it exceeds the range of elastic deformation and may undergo plastic deformation.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an elastic fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an elastic fabric, comprising an elastic layer and an inner layer, wherein the elastic layer is provided with a plurality of protruding strips on the side facing the inner layer, the inner layer is abutted by the protruding strips to form abutting strips, the length direction of the abutting strips is arranged longitudinally, the side of the inner layer opposite to the elastic layer is provided with a plurality of pleats located between two adjacent abutting strips, a cavity is formed between the pleats and the elastic layer, the degree to which the pleats protrude from the inner layer is greater than the degree to which the abutting strips protrude from the inner layer, and a plurality of restricting yarns are transversely padded on the inner layer.

[0007] The present invention is further configured such that the protrusions are arranged in a linear array on the elastic layer, and there is a gap between two adjacent protrusions along the length direction of the contact strip.

[0008] The present invention is further configured such that: the elastic layer includes an elastic part and an installation part arranged alternately in sequence; the elastic part is woven from elastic yarn; the installation part is woven from elastic colored yarn; the convex strip is located on the installation part; and a plurality of single-needle single-row tufts are woven on the elastic part.

[0009] The present invention is further configured such that both the elastic yarn and the elastic colored yarn are made of high-elastic polyester yarn twisted together.

[0010] The present invention is further configured such that: the inner layer is woven with cotton yarn to form a double rib air layer structure, the double rib air layer structure includes a front coil row and a back coil row, and the limiting yarn is sandwiched between the front coil row and the back coil row.

[0011] The present invention is further configured such that the limiting yarn is made of low-elastic polyester fiber twisted together.

[0012] In summary, this utility model has the following beneficial effects:

[0013] During fabric stretching, the elastic layer located below the pleats gradually stretches, causing the cavity between the pleats and the elastic layer to gradually shrink until they are fully adhered. At this point, the inner layer restricts the elastic layer from further deformation, preventing overstretching during unidirectional stretching. The restricting yarns provide this restriction, ensuring good lateral restraint in the inner layer. When the fabric's elasticity is relatively low, the pleats still protrude from the inner layer, and the inner layer adheres tightly to the skin, resulting in a large contact area. By incorporating raised strips, a certain level of support is created, creating a gap between the inner layer and the skin. This reduces the contact area between the skin and the pleats, minimizing the possibility of adhesion and ensuring the comfort of the inner layer. Attached Figure Description

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

[0020] An elastic fabric, such as Figure 1 and Figure 2As shown, the fabric includes an elastic layer 1 and an inner layer 2. The elastic layer 1 has several raised strips 3 on the side facing the inner layer 2. These raised strips 3 are woven into the inner layer 2 using an embroidery machine. The raised strips 3 abut against the inner layer 2, forming abutment strips 4. The abutment strips 4 are arranged longitudinally. On the side of the inner layer 2 away from the elastic layer 1, several pleats 5 are formed between adjacent abutment strips 4. A cavity is formed between the pleats 5 and the elastic layer 1. The degree to which the pleats 5 protrude from the inner layer 2 is greater than the degree to which the abutment strips 4 protrude from the inner layer 2; that is, the furthest distance between the pleats 5 and the elastic layer 1 is greater than the furthest distance between the abutment strips 4 and the elastic layer 1. Several restraining yarns 6 are transversely padded on the inner layer 2. During fabric stretching, the elastic layer 1 located below the pleats 5 will slowly stretch. At this time, the cavity between the pleats 5 and the elastic layer 1 will gradually decrease until the pleats 5 and the elastic layer 1 are completely adhered. The inner layer 2 restricts the elastic layer 1 from further deformation, thus preventing excessive stretching of the fabric during unidirectional stretching. The restricting yarn 6 has a restrictive effect, giving the inner layer 2 good lateral restriction. When the fabric's elasticity is relatively small, the pleats 5 still protrude from the inner layer 2, and the inner layer 2 adheres tightly to the skin, resulting in a relatively large contact area between the inner layer 2 and the skin. By setting the convex strips 3, the convex strips 3 can form a certain support, creating a gap between the inner layer 2 and the skin, thereby reducing the contact area between the skin and the pleats 5, reducing the possibility of the inner layer 2 sticking to the skin, and ensuring the comfort performance of the inner layer 2. In this embodiment, the ratio of pleats 5 to abutting strips 4 is 4:1. This ensures that the fabric has sufficient stretch area while also ensuring that the convex strips 3 have a certain abutting effect.

[0021] like Figure 2 and Figure 3 As shown, the convex strips 3 are arranged in a linear array on the elastic layer 1. There is a gap between two adjacent convex strips 3 along the length direction of the contact strip 4, a gap between two adjacent convex strips 3 in the transverse direction, and a gap between two adjacent convex strips 3 in the longitudinal direction. The contact strip 4 is formed by the contact of all the convex strips 3 located in the same longitudinal direction. This arrangement makes the fabric have a certain elasticity in the longitudinal direction as well, and the fabric can deform by relying on the space between two adjacent convex strips 3 in the longitudinal direction.

[0022] like Figure 3As shown, the elastic layer 1 includes an elastic part 10 and an installation part 11 arranged alternately in sequence. The elastic part 10 is woven from elastic yarn 7, and the installation part 11 is woven from elastic colored yarn 8. The convex strip 3 is located on the installation part 11. Several single-needle single-row tucks are woven on the elastic part 10. The weaving density of the single-needle single-row tucks is relatively low, which increases the overall breathability of the fabric on the one hand, and makes the area below the pleats 5 more likely to deform on the other hand, thereby reducing the obstruction of people's movements. The installation part 11 is different in color from the elastic part 10 and does not have a tuck structure, so that the weaving density of each position of the installation part 11 is uniform, thereby ensuring the stability of the convex strip 3 structure. Both the elastic yarn 7 and the elastic colored yarn 8 are made of high-elastic polyester yarn twisted together. High-elastic polyester yarn has the characteristics of good elasticity and high strength, thereby ensuring the overall elasticity of the elastic layer 1.

[0023] like Figure 1 and Figure 4 As shown, the inner layer 2 is woven with cotton yarn 9 to form a double rib air layer structure. The double rib air layer structure includes a front loop row and a back loop row. The restraining yarn 6 is sandwiched between the front loop row and the back loop row. The double rib air layer structure is relatively soft, while the cotton yarn 9 has the characteristics of being skin-friendly and warm, thus ensuring the overall warmth and softness of the inner layer 2. The restraining yarn 6 is sandwiched in the inner layer 2, so that the restraining yarn 6 does not protrude outside the inner layer 2, thus ensuring the overall softness of the inner layer 2. The restraining yarn 6 is made of low-elastic polyester yarn twisted together. Low-elastic polyester yarn has the characteristics of high strength and low elasticity, thus ensuring the restraining effect of the restraining yarn 6. The restraining yarn 6 restricts the fabric in the lateral direction. The double rib air layer structure itself is a knitted structure, so it also has a certain degree of stretch in the longitudinal direction and is not restrained by the restraining yarn 6, thus giving the fabric a certain degree of stretch in the longitudinal direction.

All technical solutions falling within the scope of this utility model's concept are protected.
