Embodiment 1

[0026] The specified amount of semi-dull PBT polyester chips is directly transported to the chip drying tower, the drying temperature is controlled at 130°C, and the drying time is controlled for 4 to 5.5 hours. The moisture content in the chips is tested. After reaching the drying standard, start the screw of the spinning equipment 1. Carry out chip spinning, see the above Table 2 for the temperature control of each zone of the spinning screw and the temperature control of the elbow and the box. Pre-crystallize the specified amount of disperse dye deep-dyed PET polyester slices at normal pressure, and control the pre-crystallization temperature at 130-136°C for 2.5-3.5 hours, and then dry it at a temperature of 150-155°C for 5-5 hours. After 6.5 hours, test the moisture content in the slices. After reaching the drying standard, start the second screw of the spinning equipment to spin the slices. The temperature of each area of ​​the spinning screw and the temperature control o...

Abstract

The invention relates to a novel two-color parallel type composite polyester fiber, which is a novel two-color parallel type composite fiber of common semi-dull PBT and modified PET polyester, and is characterized in that on a composite spinning device, a parallel type composite fiber spun by double screws has a peanut type fiber cross section, and the ratio of the PBT polyester to the modified PET polyester is 50:50. The specifications of the spun fibers are 100D/36f and DTY of 150D/72f, and the modified PET polyester used in spinning is disperse dye normal pressure deep-dyeing type polyester; the spun fiber after treatment has the same elasticity with polyurethane core spun yarn performances. With the disperse dye normal pressure deep-dyeing type polyester, the composite polyester fiber has excellent dyeing property and can effectively generate two-color effect. Besides, because two grooves are formed on the surface of the fiber, the fiber has the functions of moisture absorption and perspiration to certain extent.

Description

technical field [0001] The invention relates to a novel composite PBT polyester filament, in particular to a novel two-color side-by-side composite polyester fiber, which belongs to the technical field of polyester fibers. Background technique [0002] Since natural fibers have many excellent qualities, cotton fibers and silk fibers each have their own unique wearing comfort, how to improve the quality and function of chemical fibers has been the goal pursued by the chemical fiber industry for a long time. The development of the polyester industry has enriched our lives, and the development of many new polyester modified varieties has greatly enriched the diversity of the fabric market. In recent years, with the gradual acceleration of my country's economic development and the integration with the world trend, my country's polyester industry has made great progress. The chemical fiber market keeps up with the world trend. [0003] In recent years, the consumption of variou...
