Problems solved by technology

[0004] There is a common problem in the above-mentioned disclosed patents: the manufacturing of plied fiber fabrics by the above-mentioned method is complex and costly. In order to control costs, small batches are rarely produced, and generally large-scale production is required. Therefore, the flexibility is low, and the plied fibers produced The fabric specifications are relatively single, which cannot meet the ever-changing customer needs in the market. It is difficult to meet the customer groups who urgently need thin, smooth, high-quality, and small-batch fabrics, let alone quickly develop new products to lead the market.

Abstract

The invention discloses a process for producing superfine different shrinkage composite polyester filaments, which comprises the following steps of: (1) selecting superfine polyester FDY (Full Drawn Yarn) with the specifications of 16.5dtex to 33dtex and 12F to 48F as well as superfine POY (Polyester Oriented Yarn) with the specification of 16.5dtex to 28.6dtex and 12F to 48F; (2) stranding and networking the superfine polyester FDY and the superfine POY on a networking spooler; (3) twisting the superfine polyester FDY and the superfine POY on a chemical fiber double twisting machine to produce plied yarns with uniform tension and good cohesion after the superfine polyester FDY and the superfine POY are stranded and networked, wherein the twisting number is 1700-3500T / M; and (4) after twisting, carrying out shaping through a yarn steaming case to obtain the different shrinkage composite filament meeting the requirements. By adopting the process, not only the processing is simple and the cost is easy to control, but also small scale production can be carried out so as to meet the needs of different customer groups.

Description

technical field [0001] The invention discloses a method for manufacturing polyester superfine different shrinkage composite filaments, and belongs to the technical field of synthetic fiber fabric production. Background technique [0002] With the continuous improvement of the quality of life of human beings, the high-quality requirements of plied fiber fabrics have been raised to an important position. Universities, research institutes and production companies have invested a lot of energy in research and development. Among them, the use of plied yarns with different shrinkage properties of polyester POY and FDY has become an important means of developing high-quality fabrics. In the post-processing of fabrics made of different-shrinkage fibers, the low-shrinkage fibers naturally curl and float on the surface of the tow. This imparts high sensitivity to the fabric. [0003] CN101144198 patent discloses a one-step production method of different shrinkage fibers, polyester PO...
