Method for preparing hemp-type staple fiber into flexible auxetic composite fabric based on bonding method

Abstract

The invention relates to a method using a bonding process to prepare hemp short fibers into a flexible tension composite fabric; the method comprises the following steps: setting a template engraved with a tension structure pattern; evenly laying the hemp short fibers along the tension structure pattern on the template; spraying a bonding agent on the hemp short fibers so as to immerse the hemp short fibers, thus enhancing the contact acting force between adjacent fibers; solidifying the material so as to obtain the flexible tension composite fabric. The obtained flexible tension composite fabric can be sewed to form functional textiles like a mesh bag, a protection isolation sleeve, a water cup pad, and a curtain; the method is simple in processing, wide in suitable raw materials, wherein the raw materials comprise ramie, flax, jute, and waste cycling short fibers.

Description

technical field [0001] The invention relates to a process and application for preparing a flexible auxetic composite fabric by utilizing short hemp fibers or yarns, and belongs to the technical field of preparation and application of textile materials and composite materials thereof. Background technique [0002] Although staple fiber can prepare yarn and weave fabrics at present, its process is complicated, especially hemp fiber. The short fiber of hemp, the large difference between batches, and the great influence of humidity on the strength further increase the processing difficulty. Not only that, but there are also difficulties in the processing of hemp-type staple fiber, and the product has many defects and low price, which is due to the lack of new technology of the product. Therefore, it is of great significance for the development of hemp fibers to develop hemp fabrics with new structures and new functions, and to improve the added value and performance of products...
