Abstract
The application relates to the field of fabrics, and particularly discloses a stab-resistant garment fabric and a preparation method thereof. The stab-resistant garment fabric comprises at least one base fabric layer, wherein the base fabric layer is prepared from stab-resistant yarns, the stab-resistant yarns are formed by double twisting composite fibers, and the composite fibers comprise at least two of ultra-high molecular weight polyethylene fibers, aramid fibers and glass fibers. The preparation method comprises the following steps: and (3) treating the shear thickening liquid: taking the shear thickening liquid and placing the shear thickening liquid in a vacuum environment for defoaming treatment; taking a base cloth layer, soaking the base cloth layer in shear thickening liquid, and vertically suspending the base cloth layer for 10s after soaking treatment for 25-35 s; and after drying treatment, collecting the dry base fabric, thermally sealing the base fabric in a polyethylene bag, and performing vacuum compression treatment to obtain the stab-resistant garment material. This application is through having optimized composite fiber's component, can effectively combine each fibrous beneficial effect, improves the base cloth layer structural performance of preparation to improve the clothing material of preventing stinging and prevent stinging the performance.
Description
Technical Field
The application relates to the field of fabrics, in particular to a stab-resistant garment fabric and a preparation method thereof.
Background
Generally stab-resistant materials can be divided into three categories according to their flexibility: hard stab-resistant materials, semi-hard stab-resistant materials, and flexible stab-resistant materials.
