Production method of cool-feeling Sorona fiber

Abstract

The invention relates to a production method of a cool-feeling Sorona fiber. Dupont PTT slices are adopted, cool-feeling master batches are added in the spinning process, a drum is adopted for tackifying, and a low-temperature and long-time drying mode, a lower spinning temperature, a continuous Roots blower flexible conveying mode, a dust separation device, a high-precision master batch injection machine, a parallel spinneret plate for composite spinning and a side blowing cooling rectifier are adopted, so that a produced new product has the characteristics of more uniform elasticity and fineness and more stable product quality, and has good durability and a good dyeing property; and ordinary disperse dye can be used for normal-pressure boiling dyeing, no carrier is needed, and dyed fibers are bright in color and excellent in color fastness and chlorine resistance. The product has the advantages of soft hand feeling, stain resistance, fluffiness, moisture absorption and quick drying, and the processed fabric is flat, smooth, crease-resistant, easy-care, stable in size and moderate in elasticity. Particularly, after being worn in summer, the sportswear made of the fiber is cool, light in skin, moisture-absorbing, sweat-releasing, comfortable and healthy.

Description

technical field [0001] The invention relates to the field of chemical fiber production and processing, in particular to a production method of cool-feeling elastic fiber. Background technique [0002] After years of rapid development of my country's chemical fiber industry, the output of chemical fiber has continued to rank first in the world since 1998, and China is the largest producer of chemical fiber in the world. In 2017, my country's chemical fiber output was nearly 50 million tons, accounting for more than 70% of the total global fiber output. However, the "quantity" of the industry has grown significantly. There are many bulk and conventional products, and the research and development level of high-tech products such as modified fibers, high-fidelity fibers, special functional fibers, ultra-fine denier fibers, and functional fibers is low. In recent years, my country's chemical fiber industry has stepped up innovation efforts, focused on the overall technological p...
