Embodiment Construction
[0019] The present invention will be further described below in conjunction with specific examples.
[0020] The production method of a kind of cool-feeling cable-elastic fiber involved in the present invention has the following production steps. The selected PET raw material is transported, pre-crystallized, dried, melted and extruded to form a spinning melt and enter the spinning through the box metering pump. Components; the selected PTT raw materials are conveyed, solid-phase viscosified, dried, melt-extruded, and filtered to form a spinning melt through a box metering pump for spinning components; PET spinning melt and PTT spinning melt are spinning The melt is collected in the filament assembly, and the collected melt is spun and then subjected to side blowing, oiling, pre-netting, drafting and setting, main network, winding forming, inspection, grading and packaging, and finished products. The drying temperature of PET chips is 165°C±5°C. The drying temperature of PTT ...

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...
