Problems solved by technology

However, polyester fibers have high modulus and no polar groups, and the fabrics woven from them have a hard hand, poor air permeability and moisture absorption
These shortcomings limit its application in higher demanding fields
The existing polyester low-stretch yarn products are relatively single in variety, and the fabrics woven as raw materials have a single style and cannot meet the requirements. The woven fabrics can no longer meet the high requirements in terms of feel, appearance, texture, luster and elasticity.
[0003] In addition, with the advancement of science and technology, people's demand for smart wearable textiles continues to increase. Embedding functional yarns into fabrics to obtain textiles with multiple functions such as sensing, conduction, and luminescence has become a research hotspot; The way the fibers attach to the fabric, which reduces the comfort of the fabric

Embodiment 1

[0025] like figure 1 Shown, a kind of preparation technology of the DTY plied yarn with special luster, comprises the following steps:

[0026] Step (1), preparation of semi-dull FDY yarn: Pre-crystallize, homogenize and dry the polyester chips to obtain PET dry chips, and enter the screw extruder into the screw extruder, which is divided into eight zones. The temperature of the screw of the press is 250~275°C. After high-temperature melting, the melt is extruded, and the melt enters the spinning assembly for melt spinning. The spinning temperature is 245°C; figure 2 As shown, the spinneret holes on the spinneret in the spinning assembly are a flat structure formed of two rows of Y-shaped hole groups symmetrically arranged, each row of Y-shaped hole groups includes three Y-shaped holes, and two rows of Y-shaped holes The Y-shaped holes in the group are obliquely close to each other; the fine flow of melt ejected from the spinning assembly is solidified and cooled into filame...

Embodiment 2

[0031] like figure 1 Shown, a kind of preparation technology of the DTY plied yarn with special luster, comprises the following steps:

[0032] Step (1), preparation of semi-dull FDY yarn: Pre-crystallize, homogenize and dry the polyester chips to obtain PET dry chips, and enter the screw extruder into the screw extruder, which is divided into eight zones. The temperature of the screw of the press is 250~275°C. After high-temperature melting, the melt is extruded, and the melt enters the spinning assembly for melt spinning. The spinning temperature is 260°C; among them, such as figure 2 As shown, the spinneret holes on the spinneret in the spinning assembly are a flat structure formed of two rows of Y-shaped hole groups symmetrically arranged, each row of Y-shaped hole groups includes three Y-shaped holes, and two rows of Y-shaped holes The Y-shaped holes in the group are obliquely close to each other; the fine flow of melt ejected from the spinning assembly is solidified an...

Embodiment 3

[0037] like figure 1 Shown, a kind of preparation technology of the DTY plied yarn with special luster, comprises the following steps:

[0038] Step (1), preparation of semi-dull FDY yarn: Pre-crystallize, homogenize and dry the polyester chips to obtain PET dry chips, and enter the screw extruder into the screw extruder, which is divided into eight zones. The temperature of the screw of the press is 250~275°C. After high-temperature melting, the melt is extruded, and the melt enters the spinning assembly for melt spinning. The spinning temperature is 270°C; among them, such as figure 2 As shown, the spinneret holes on the spinneret in the spinning assembly are a flat structure formed of two rows of Y-shaped hole groups symmetrically arranged, each row of Y-shaped hole groups includes three Y-shaped holes, and two rows of Y-shaped holes The Y-shaped holes in the group are obliquely close to each other; the fine stream of melt ejected from the spinning assembly is solidified an...

Abstract

The present invention discloses a preparation process of a multi-ply DTY with special gloss. The process comprises the following steps of preparing a semi-dull FDY; preparing a flash DTY; by taking adull FDY as a core yarn and taking a carbon nanotube yarn as a skin yarn, performing wrapping to obtain an intelligent wrapped yarn; and by taking the flash DTY as a core yarn and taking the intelligent wrapped yarn as a skin yarn, performing wrapping to obtain the multi-ply DTY with the special gloss. The multi-ply DTY prepared by the process has the relatively special gloss, fluffy and soft handfeeling, certain elasticity and relatively good moisture absorption, and can be used as an intelligent yarn.

Description

technical field [0001] The invention belongs to the technical field of fiber preparation, and in particular relates to a preparation process of DTY plied yarn with special luster. Background technique [0002] As one of the three main fibers in synthetic fibers, polyester fiber (polyester) is widely used in clothing fabrics and other non-clothing fields because of its excellent physical and chemical properties. However, polyester fibers have high modulus and no polar groups, and the fabrics woven from them have a hard hand, poor air permeability and hygroscopicity. These disadvantages limit its application in more demanding fields. The existing polyester low-stretch yarn products are relatively single in variety, and the fabrics woven as raw materials have a single style and cannot meet the requirements. The woven fabrics cannot meet the high requirements in terms of hand feel, appearance, texture, luster and elasticity. [0003] In addition, with the advancement of scienc...
