Embodiment Construction

[0011] A method for manufacturing polyester variable twist yarn, comprising a spinning process part and a post-processing process part, the pre-crystallization temperature of polyester chips in the spinning process is 150-190 °C, the drying temperature is 152-192 °C, polyester The melting temperature of the slice is divided into 6 different temperature zones. The number of twists in the post-processing process is 3500-4000 pieces / m. During the normal process of stabilizing the "Z" twist, the frequency conversion control is used to make the twist fluctuate to cause reverse " S" twist. The temperature of the pre-crystallization is 168°C, and the drying temperature is 170°C. In the spinning process, a screw extruder is used to divide the melting temperature of polyester chips into 6 different temperature zones, and the screw extruder is divided into 6 zones, and the melting temperatures of zones 1-6 of the screw extruder are respectively The settings are 287°C, 288°C, 289°C, 289...

Abstract

The invention discloses a manufacturing method for changing polyester fibers into thrown silk, which comprises a spinning process part and a post-processing process part. The pre-crystallization temperature of a polyester chip in the spinning process is 150 to 190 DEG C, the drying temperature is 152 to 192 DEG C, the melting temperature of the polyester chip is divided into six different temperature areas, the twisting number in the post-processing process part is 3500 to 4000 per meter, and in the normal Z-shaped twisting steady processing course, the twisting degree is fluctuated through variable frequency control to cause the reverse S-shaped twisting. The twisted textile changed from polyester fibers and manufactured through the technical proposal is not easy to wrinkle, and the handfeeling is good.

Description

technical field [0001] The invention relates to a method for manufacturing flax-like chemical fiber, in particular to a method for manufacturing polyester variable twist yarn. Background technique [0002] At present, natural flax is widely used as a raw material for decorative cloth due to its good hand feeling, moisture absorption and breathability. Functionalization, natural flax is not conducive to continuous application due to its own defects such as easy wrinkling and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for manufacturing polyester variable-twist yarn, which can manufacture polyester variable-twist yarn, and the polyester variable-twist yarn fabric is not easy to wrinkle and maintains a good hand feeling. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following scheme: a manufacturing method of polyester variable twist yarn...
