Abstract

The invention relates to a preparation method of a high-strength yarn. The preparation method comprises the following steps of mixing 80-150 parts of polylactic acid fibers and 5-15 parts of polyacrylate polymer components, and wetting with a wetting agent; adding 10-25 parts of cross-linked starch into the obtained mixture, extruding, melting, drawing and stretching to form filaments, and kneading and winding the filaments to form grey yarns. The high-strength yarn prepared by the invention is energy-saving and environment-friendly, and meets the comfort requirements of people on novel fiber fabrics.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a high-strength yarn and a preparation method thereof. Background technique [0002] As we all know, sizing is a key process in the textile production process, but size is one of the largest sources of pollution in the textile industry. In order to reduce the pollution of size, the current main way is to research and develop low-pollution green size. Regardless of whether it is sizing traditional yarns or new fiber yarns, it is also required to use green sizing and achieve green sizing. Due to the depletion of world oil, the increasingly severe situation of environmental protection, and the improvement of economic development and people's living standards, the comfort performance of textiles has become an indispensable factor. In the later period, we began to pay attention to the development of new textile fibers based on natural raw materials, including three new types of fibe...
