The air-twisted yarn of the present invention comprises: a central core yarn (Coreyam), which adopts a thermoplastic fiber with self-winding elastic function, and an outer sheath sheath yarn (Effect yam), which adopts a general thermoplastic fiber; twisting the yarn through air Air textured machine twists the yarn into an air-twisted yarn. After the weaving process, in the dyeing and finishing process, the high temperature during processing is used to cause a shrinkage difference in the thermoplastic fibers with self-winding elasticity. And to achieve fabrics with elastic effects. [Previous technology] The traditional manufacturing method of air-twisted yarns, such as disclosed in the patent No. 144452 "moisture wicking yarn", is mainly a polyester or polyamide synthetic fiber with a conventional profiled cross-section structure. The raw silk or processed yarn is used as the core yarn and sheath yarn, and the yarn is twisted into a yarn type through air twist processing. However, the fabric woven with this yarn type does not have elasticity and is not comfortable to wear. In addition, related manufacturers also produce short-fiber elastic composite yarns covered with staple fibers on the periphery of LYCRA (Spandex); or single or double wraps are wrapped around the periphery of LYCRA (Spandex), or the yarns are exposed to high-speed air The knots are wrapped around LYCRA (Spandex) to produce long-fiber elastic composite yarns (covering yam); although this type of yarn also has elasticity, but in addition to complex manufacturing processes, polyurethane silk (Spandex) still has the following Disadvantages: 1. Due to the technical complexity of raw materials and processes, the cost is high. 5 558571 Rev. April 2003 2. It is not resistant to humidity and heat, so it is not suitable for dyeing and finishing at high temperature, and the color is easy to be brittle. 3. Alkali-resistant (NaOH) reduction processing. 4. Due to the large elasticity, it is difficult to control the tension of the weaving and dyeing and finishing process, and the processing difficulty is extremely high. It affects product quality and industrial efficiency. ^ Therefore, the present invention aims at the problems caused by the various existing related products mentioned above, and uses various processing technologies and raw material selections to actively research and try. After continuous testing and improvement, it has developed a combination of various practically effective functions. High-grade yarns with the advantages of elastic composite yarns have extremely high industrial production prices. [Content] The air-twisted yarn of the present invention is mainly composed of core yarns of two types of thermoplastic polymers with different shrinkage ratios that are melt-spun through a melt-composite spinning nozzle at a ratio of 7: 3 to 3: 7. Thermoplastic polymers with different shrinkage ratios have mutually aligned features in the cross section of the fiber. The manufacturing schematic diagram is shown in Figure 4. The fifth diagram is a schematic drawing of the cross-sections of several types of core yarn composite fibers that can be applied to the present invention. When hot water is encountered in the dyeing and finishing project, due to the different shrinkage rates of the two materials, the interface will form a spring-like spiral due to the difference in shrinkage stress, resulting in self-winding elasticity. Sheath yarn (Effect yam) (4) Take 1 or 2 or 3 general thermoplastic fibers, and its specifications and yarn types can be appropriately selected according to the desired effect and function of the fabric. According to the schematic diagram of the processing flow in the first figure, the core yarn (3) and sheath yarn (4) or (5) are respectively fed through different feed rollers (W1.1) and (W1.2) at different feed rates. After feeding in air twist twist 6 558571 processing device (7) (as shown in the enlarged view of the third figure), the processing will be repaired in April 2003 1 ^ work yarn (8) is derived from the second roller (W2), Finally, the yarn is wound by controlling the feed rate between the third roller (W3) and the take-up roller (WW). The elastic air-twisted yarn (8) of the present invention can be woven into fabrics of various shapes through a knitting machine, a shuttle, and a shuttleless loom. Since the elastic effect does not appear before the hot water treatment, there is no problem of tension control. , Weaving is better than the existing elastic composite yarn; finally, after dyeing and finishing, printing processing, it can give the fabric excellent elasticity and excellent wearing comfort. In summary, the present invention is a manufacturing method developed for a self-winding elastic air-twisted processing yarn. In order to simply and specifically describe the features of the present invention, the following examples are used to briefly explain, but the present invention is not limited to The following examples.
