Description

a stretchy fabric

technical field

The present invention relates to elastic fabrics.

Background technique

Fabric is the material used to make clothing. As one of the three elements of clothing, fabrics can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing.

Woven fabrics are woven through warp yarns and weft yarns. According to the texture classification, the current fabrics mainly include plain weave fabrics and twill weave fabrics. As people's needs are different, the requirements for fabrics are not the same.

For the existing woven fabrics, the warp and weft weaving structure of one layer structure is used, which is limited by the thickness of the yarn, so that the thickness of the fabric is limited. If thick fabrics are to be manufactured, multi-layer fabrics are generally used to achieve this by gluing. , On the one hand, the glue is not environmentally friendly, on the other hand, it affects the softness of the fabric, and on the other hand, it is prone to layer-to-layer peeling, which affects the service life of the fabric.

For single-layer fabrics, the warp yarns are exposed on the surface. Therefore, when the fabric is used for a long time, the warp yarns are easily damaged. For fabrics using elastic warp yarns, once the warp yarns are damaged, the elasticity of the fabric will be affected. .

Contents of the invention

The object of the present invention is to provide an elastic fabric. In the fabric of the present invention, adjacent braided layers are woven together by sharing the warp yarn, which is not easy to peel off, and the fabric has good flexibility and long elastic life.

In order to achieve the above object, an elastic fabric comprises more than two layers of braided layers, each layer of braided layers includes weft yarns and warp yarns, and adjacent braided layers share warp yarns, and the warp yarns are elastic warp yarns; the adjacent weft yarns of the bottom braided layer Weft yarns having one or more weaving layers adjacent to the underlying weaving layer therebetween.

In the above fabric structure, the adjacent braided layers share an elastic warp yarn, so that the adjacent braided layers are woven together through the elastic warp yarn, so as to avoid the phenomenon of peeling off of the adjacent braided layers. During the weaving process, the elastic warp yarn is in a stretched state. After the weft yarns are woven, the weft yarns approach each other under the rebound of the elastic warp yarns, so that the weaving layers in the fabric form an obvious layered structure. The weft yarn of other layers will not be exposed except the weft yarn of the bottom layer. The warp yarn is hidden in the weft yarn, which can better protect the elastic warp yarn and make the elastic warp yarn not easy to break. Therefore, the elastic life of the fabric is long; the structure is also There is no need for viscose to realize the connection between the braided layers, so that the flexibility of the fabric is good, and the fabric has elasticity in the warp direction due to the existence of the elastic warp yarn. When adjacent braided layers share elastic warp yarns, the friction between warp yarns and weft yarns and between weft yarns increases, which can effectively reduce yarn collapse. The use of multi-layer braided layers can increase the thickness of the fabric. Compared with the existing single-layer fabric, it does not need to increase the thickness of the fabric by increasing the count of the yarn, and after the fabric is pulled apart, the gap between the weft yarns The gap is small, not easy to pilling, broken wire. For the fabric structure of the present invention, it is an elastic fabric after the weaving is completed. Therefore, one-size-fits-all wearables can be made, and self-cultivation clothes can be made, which can better reflect the body curve. At the same time, when the human body wears the clothes in motion, it is not easily affected Clothing has no stretch effect. In addition, due to the use of multiple layers of shared elastic warp yarns, the fabric has good stability, is not easy to wrinkle, deform, and has high flatness.

Further, the braided layer is provided with two layers, with weaving points between the weft yarns and warp yarns of the surface layer, and weaving points between the weft yarns and warp yarns of the bottom layer.

Further, the warp yarns are hollow covered elastic yarns or twisted covered elastic yarns. Empty covered elastic yarn or twisted covered elastic yarn has good elasticity, so that the warp yarn has better elasticity, and at the same time, it can make the fabric feel soft and beautiful.

Further, two surface layer weft yarns are arranged between adjacent bottom weft yarns.

Further, the two weft weave points adjacent to the warp and the surface are respectively 1 warp weave point, 1 weft weave point, 1 warp weave point, 5 weft weave points and 3 weft weave points, 1 warp weave point, 1 weft weave point, 2 warp weave points and 1 weft weave points; warp and bottom weft weave points are 7 warp weave points and 1 weft weave point. Using this weave point weaving can form intersecting double twill lines on the surface of the fabric, which not only makes the fabric elastic, but also has a beautiful appearance and a good three-dimensional effect, and at the same time can increase the strength of the fabric.

Further, the weave point of the warp yarn and the weft yarn of the surface layer is 1 warp weave point and 1 weft weave point; the weave point of the warp yarn and the weft yarn of the bottom layer is 1 warp weave point and 1 weft weave point.

Further, the warp density of the elastic fabric is 60-200/inch, and the weft density is 50-200/inch.
