Embodiment Construction

[0017] The present invention uses a nylon false-twist texturing machine to carry out a one-step method for producing nylon and spandex empty covered yarn. A set of spandex roller device 7, a second thread cutter 8, and a second thread detector are installed on the original nylon machine. The device 9, the network device 11, the intermediate auxiliary roller (W2x) and the thread transfer device 10 for doubling are placed in a relatively reasonable position on the nylon false twister through the connecting piece to ensure the optimization of the silk path. The method includes the following steps:

[0018] A) The polyamide yarn (POY) is led out from the original yarn frame 1, and enters the first feeding roller 3 through the first thread cutter 2 on the false twist texturing machine, and is heated by the deformation hot box 4, and then enters the cooling device 5 and false The twister 6 (including the thread guide) is led out and sucked by a sniffer.

[0019] B) The spandex thread is...

Abstract

The present invention provides a method for making nylon-polyurethane fiber blended yarn by utilizing false-twist texturing machine and adopting one-step process. Said method includes the following steps: (A), making nylon raw yarn be drawn out from raw yarn frame, and making said nylon raw yarn be fed into first roller by means of first yam-cutting device of false-twist texturing machine, then fed into a texturing hot-box, and passed through a cooling device and a false-twister, then attracted by suction gun; (B), making polyurethane fiber yarn be drawn out from polyurethane fiber roller, and making said polyurethane fiber yarn be passed through second yarn-cutting device and second yarn-detector, then be attracted by suction gun, then combined with nylon yarn; and (C), making the combined two yarns be passed through intermediate roller, air-entanglement jet device, second auxiliary roller and first yarn detector, and be reached to oiling roller, finally passed through winding roller and winding to make formation.

Description

Technical field [0001] The invention relates to a method for producing high value-added fancy yarn by adopting a one-step method, in particular to a method for manufacturing nylon hollow yarn by using a false twist texturing machine. Background technique [0002] The false twist texturing machine is a post-processing equipment for chemical fiber filaments, which can process the raw filaments into textured yarns with high elastic properties. In order to meet the needs of the continuous development of the domestic fancy and colored spinning market, the inventors have developed a series of false twist texturing machines, which are equipment for false twisting of polyamide yarn (POY) into nylon high elastic yarn. [0003] With the continuous expansion of demand for textile fabrics, various types of special fibers, special processing techniques, and special style yarns have emerged. Nylon air-covered composite yarn is a popular special yarn in the market in recent years. It is compose...
