Abstract

The invention discloses a chinlon 6 POY / spandex stretching false-twisting covered yarn and an one step preparation method thereof, which are used for performing stretching, false-twisting and covering and winding forming processes of chinlon 6 POY / spandex on the same machine. After chinlon 6 POY passes through a first roller and a twisting stopper and is heated by a heating box device, the chinlon 6 POY is inputted into a false twister by a cooling plate for stretching and false-twisting, so as to obtain chinlon 6 DTY, and then the chinlon 6 DTY and spandex stretched by certain times are simultaneously inputted into a doubling device at different speeds by a tension self-check device, are pulled to a covering device by a second roller for covering, and pass through an auxiliary roller and an oiling device and are subjected to winding forming by a winding forming device to obtain the chinlon 6 POY / spandex stretching false-twisting covered yarn. The chinlon 6 POY / spandex stretching false-twisting covered yarn has the advantages of short technological process, low energy consumption, high production efficiency, low cost, high additional value, good product quality, excellent covering evenness stability and dyeing evenness, and the like.

Description

technical field [0001] The invention relates to a functionally differentiated textile fiber material and a preparation method thereof, in particular to a nylon 6POY / spandex stretched false-twisted covered yarn prepared by a one-step production process, which belongs to the technical field of synthetic fibers. Background technique [0002] Nylon, the chemical name is polyamide (Polyamide) fiber, also known as nylon, nylon (Nylon), English code PA, nylon is one of the three major synthetic fibers in the chemical fiber industry, and it is also the first synthetic fiber and the earliest in the world. Synthetic fibers for industrial production. At present, the nylon products on the domestic and foreign markets mainly include nylon FDY, POY, DTY, ATY, network yarn, mixed fiber yarn, false twist textured yarn, air textured yarn, core yarn, covering yarn, etc. Among them, nylon 6POY / spandex coated silk products are mainly prepared by adopting two-step or three-step stretching false...
