Embodiment 1 2

[0029] Example 1 Preparation of two-component polyester filament different shrinkage air multiple textured yarn

[0030] Use polyester high-shrinkage filament as raw material, supplier Xiamen Xianglu Chemical Fiber Factory Specification 33dtex / 12f single fiber linear density 2.75, boiling water shrinkage 41.2%, oil content 0.87%,

[0031] The preparation of the two-component shrinkage yarn is completed in a boiling water treatment tank. The specification of the A-component yarn is 33dtex / 12f×3, the treatment time is 50 seconds, and the remaining boiling water shrinkage rate is 30%, and the specification of the B-component yarn is 33dtex / 12f×3. The processing time is 150 seconds, and the remaining boiling water shrinkage rate is 15%. Since the A component tow has a higher boiling water shrinkage rate than the B component tow, after the different shrinkage deformation processing, the core layer yarn will be formed, while the B group Split filaments form cortical filaments. The ...

Abstract

The invention relates to a processing method of polyester filament differential shrinkage air multi-textured yarns. The method is characterized by taking the high shrinkage polyester filaments with boiling water shrinkage being 30-60% as raw materials, putting the high shrinkage polyester filaments into the boiling water to quickly shrink to become differential shrinkage filaments and obtaining the polyester filament differential shrinkage air multi-textured yarns through air texturing of the polyester differential shrinkage filaments under normal temperature and differential shrinkage processing, namely heat treatment in the boiling water at the temperature of 98-100 DEG C. The processing method has the following advantages: the whole process for preparing the polyester filament differential shrinkage air textured yarns is completed under normal temperature, thus avoiding high temperature degradation damage of the fiber structures, and the product quality is excellent; and the raw materials are easy to obtain, the process is simple, the high temperature equipment is not needed, the energy is saved, the pollution of the harmful gases generated through decomposition of polymers generated through high temperature treatment is avoided, the cost is low and the benefits are high.

Description

technical field [0001] The invention belongs to the field of textiles, and relates to a processing method of polyester filament different-shrinkage air-multiple deformed yarn, that is, a processing method of the deformed yarn under normal temperature (below 100 DEG C) and humid heat conditions. Background technique [0002] Utilizing the principle of turbulent action of compressed air flow in the nozzle, two groups of chemical fiber filaments with the same or different feeding rates can form a typical sheath-core structure to manufacture air-textured yarns, which is a popular technology nowadays. [0003] The information of different shrinkage air textured yarns made of chemical fiber filaments such as polyester and nylon 6 as raw materials has also been reported, but from the perspective of processing methods, dry heat processing methods are generally used, and the setting temperature often exceeds 100 °C (Jiang Yan.
