Problems solved by technology

From the test results, there is still a certain gap in the wool-like effect, and the hand feel and appearance indicators are still unsatisfactory. The ordinary different shrinkage air multi-textured yarn still feels stiff, has high bending stiffness, and the luster is still not soft enough. The high reflectivity makes its wool-like products still not meet the high-grade requirements

[0024] Two-component superfine polyester filament different shrinkage air multiple textured yarn processing method

[0025] The raw material of component A is ordinary polyester pre-drawn filament, which is used as core yarn, and the specification is 75dtex / 24f. The raw material of component B is superfine polyester filament with a specification of 50dtex / 48f. Entering the different shrinkage yarn preparation process, the improved process is adopted on the parallel drawing machine: A component is 72 (75dex / 24f×3), the draft ratio is 3.0, and the hot plate temperature is 130°C; B component is ultra-fine polyester filament , as leather silk, specification 50dex / 48f, enter the different shrinkage yarn preparation process on the parallel drawing machine, the improved process is: B component is 96 (50dex / 48f×2), the draft ratio is 1.2 times, heat Plate temperature 160°C. Then it is input into the air texturing machine in the form of sheath-core feeding. The improved process is as...

[0027] Four-component superfine polyester filament different shrinkage air multiple textured yarn processing method

[0028] Components A and B use ordinary polyester pre-drawn yarn as the core yarn with a specification of 75dex / 24f; components C and D use ultra-fine polyester filament as the skin yarn with a specification of 50dex / 48f. Entering the different shrinkage yarn preparation process, the improved process is adopted on the parallel drawing machine: A component is 48 strands (75dex / 24f×2), the draw ratio is 3.0, and the hot plate temperature is 130°C. Component B consists of 24 strands (75dex / 24f), the draw ratio is 2.5, and the hot plate temperature is 140°C. Component C is 48 strands (50dex / 48f), the draw ratio is 1.4, and the hot plate temperature is 150°C. Component D consists of 48 strands (50dex / 48f) with a draw ratio of 1.2 times and a hot plate temperature of 160°C. Then it enters the air texturing machine, and its improved process is as follows: using the s...

Abstract

The invention relates to a processing method of differential-shrinkage air multi-textured yarn of superfine polyester filament yarn, which comprises the following steps: in a preparation procedure of differential-shrinkage filament, drawing and extending 1-3 groups of core filament with different shrinkage ratios for 2-5 times at 90-160 DEG C, and drawing and extending 1-6 groups of skin filament with different shrinkage ratios for 1-3 times at 140-200 DEG C; in an air deformation processing procedure, merging the core filament and then feeding merged core filament from a core filament roller at an over feed rate of 3-8% by adopting a skin core feeding way, and merging the skin filament and then feeding the skin filament from a skin filament roller, wherein the over feed rate of the skin filament roller is 10-25%; the pressure of an air nozzle is 5-10 kg / cm2; the barometric conditioning quantity is plus or minus 0.2-0.5kg / cm2; the wetting amount of the core filament is 0.3l / h; the skin filament is not wetted; and the under feed rate is 80-98%. The differential-shrinkage deformation processing procedure can adopt a yarn way or a way that weaving is performed first and then differential-shrinkage texturing processing is carried out on a textile on a yarn or textile thermal treatment device for 0.5-5.0 minutes; and yarn treatment temperature is 180-200 DEG C. By adopting the method, the effect of simulating cashmere deformation processing can be achieved.

Description

technical field [0001] The invention belongs to the field of textiles, and relates to a processing method of superfine polyester filament different-shrinkage air-multiple deformed yarn. technical background [0002] Using the principle of turbulent action of compressed air in the nozzle, two groups of chemical fiber filaments with the same feeding rate can form a parallel yarn structure or two groups of filaments with different feeding rates can form a typical sheath-core structure to produce air textured yarn It is already a popular technology today (Wang Shanyuan. Deformed yarn [M]. Shanghai: Shanghai Science and Technology Press, 1992). Using ordinary chemical fiber filaments, mainly polyester filaments and nylon filaments, it has also been reported to manufacture different shrinkage air multiple deformed yarns. Processed Yarn Structure and Properties. Doctoral Dissertation of Donghua University, 2006.). [0003] However, no matter it is the above-mentioned chemical fib...
