Embodiment Construction

[0015] A method for manufacturing modified polyester section twisted yarn, comprising a spinning process part and a post-processing process part, in the spinning process, the pre-crystallization temperature of cationic modified polyester chips is 150-190 °C, and the drying temperature is 152-150 °C. 192°C, the drawing ratio of the spinning spinneret is above 100, high twist is used in the post-processing process, the wire guide is refitted on the cooling plate to increase the temperature of the setting hot box, and the appropriate second overfeed of 3.0% is selected to increase the strength of the tow Twist effect and twist transfer, forced heat setting at 195°C. The pre-crystallization temperature of the cation-modified polyester chips is 158°C, and the drying temperature is 160°C. The drying conditions of the cation-modified polyester chips in the spinning process are that the water content of the dry chips is controlled below 30 ppm, and the intrinsic viscosity drop of the ...

Abstract

The invention discloses a method for producing modified polyester section thrown silk, comprising a spinning technical part and a post-processing technical part. In the spinning technical part, the temperature of pre-crystallization for a cationic modified polyester chip is between 150 and 190 DEG C, and the drying temperature for the cationic modified polyester chip is between 152 and 192 DEG C; and the draw ratio of a spinning nozzle is over 100. In the post-processing technical part, high twist number is adopted, a cooling plate is provided with a guide block to improve the temperature of a setting hot box, and 3.0 percent of the second overfeeding rate is suitably selected to improve the heavy twisting effect and the twist transfer for filament bundles; and heat setting is forcibly carried out at 195 DEG C. The method can produce the modified polyester section thrown silk which can maintain the excellent performance of bast fibers and make beneficial modification to the bast fibers, and is applicable to textiles.

Description

technical field [0001] The invention relates to a method for manufacturing hemp-like chemical fiber, in particular to a method for manufacturing modified polyester twisted yarn. Background technique [0002] Hemp fiber has excellent properties such as water absorption, moisture absorption, breathability, antibacterial, antibacterial, and anti-corrosion properties. The textile products made of hemp fiber are unique in their unique crisp, rough and natural style. And hemp fabric has good drape, no flash, no aurora, good wrinkle resistance, good water swelling, etc., so hemp fabric is suitable for summer clothing, bed sheets, bedding, mosquito nets, curtain screens, decorative fabrics, etc. But because the natural hemp fabric is expensive, it is not conducive to popularization and application, so the hemp-like fiber fabric with better cost performance has emerged at the historic moment. Contents of the invention [0003] The technical problem to be solved by the present inve...
