Abstract

The invention relates to the field of fabrics, in particular to a light-weight four-way stretch fabric which comprises a fabric body, the fabric body comprises an outer layer and an inner layer, a moisture absorption layer is arranged between the outer layer and the inner layer, and the outer layer and the inner layer are formed by weaving first yarns and second yarns through plain weaves respectively. The first yarns are formed by doubling and twisting high-resilience chinlon and spandex to form twisted yarns, and the second yarns are formed by wrapping the spandex with hollow chinlon to form core-spun yarns. The 75D chinlon and the 45D spandex which are good in rebound resilience and flexibility are doubled and twisted into the stretch yarn to serve as the warp yarn, and the balance stability of warp-direction elasticity is ensured; the high-performance covering yarn formed by wrapping the 75D chinlon of the hollow structure with the 45D spandex is adopted as the weft yarn, due to the fact that the interior of the wrapping chinlon fiber is of the hollow structure, air can be stored in a cavity, compared with conventional chinlon of the same specification, the fabric is lighter and better in heat preservation, and meanwhile the corresponding moisture absorption effect can be improved through the moisture absorption layer; the three-layer fabric structure not only improves the wrinkle resistance and the anti-permeation effect of the fabric, but also prevents the fabric from being too thick, heavy and stiff.

Description

Technical Field

[0001] The invention relates to the technical field of fabrics, and in particular to a lightweight four-way stretch fabric and a manufacturing process thereof. Background Art

[0002] When traditional thin fabrics are used in the production of jackets or pants, they require reinforcement materials such as composite gauze / cotton, or they must be used in combination with linings to make clothing. Although composite gauze, cotton and other materials can significantly improve the strength and crispness of the fabric, the hand feel and lightness will decrease. Although using thin fabrics in combination with linings to make clothing is a conventional method, it has defects such as lining falling off, reducing the slimness of the clothing and increasing the weight of the clothing.

[0027] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0028] Reference Figure 1-7 The present invention provides a lightweight four-way stretch fabric, including a fabric body 1, the fabric body including an outer layer 2 and an inner layer 3, a moisture absorption layer 4 is provided between the outer layer 2 and the inner layer 3, the outer layer 2 and the inner layer 3 are woven by a first yarn 5 and a second yarn 6 respectively through a plain weave, the first yarn 5 includes high resilience nylon and spandex twisted together to form a twisted yarn, and the second yarn 6 is made of spandex wrapped with an internal hollow nylon to form a core-spun yarn.
