Problems solved by technology

However, this kind of suede-like fabric is thin and not fluffy due to the raw material microfiber, which is easy to break and not wear-resistant after sanding treatment, so that the entire production process has low efficiency and high defective rate, which is not conducive to widespread promotion and use.

preparation example Construction

[0017] A preparation process of high-shrinkage island-in-the-sea yarns. Firstly, the sea-island POY yarns and high-shrinkage FDY yarns are drawn out from the corresponding wire racks, and then the following processes are completed on the false twist texturing machine:

[0018] 1) Feed the sea-island POY yarn and the high-shrinkage FDY yarn drawn out from the wire frame into the first roller and the zero roller on the false twist texturing machine, and the sea-island POY yarn is sent to the deformation heating box for heating after passing through the first roller After being processed by the cooling plate, it is fed into the false twister for twisting, and after twisting, the sea-island textured yarn with twist and bulkiness is obtained;

[0019] 2) The sea-island textured yarn and high-shrinkage FDY yarn obtained in step 1) are fed to the two rollers together. After passing through the two rollers, the sea-island textured yarn enters the shaping hot box to be heated and shaped...

Embodiment 1

[0025] The sea-island POY yarn with a specification of 165D / 48F and the high-shrinkage FDY yarn with a specification of 70D / 36F drawn out from the wire rack are introduced into the false twist texturing machine, and are fed into the false twist texturing machine at a speed of The first roller at 312m / min and the zero roller at a speed of 550m / min, among which the island-shaped POY yarn is sent to the deformation heating box for heating treatment after passing through the first roller. Twisting for a 6600r / min false twister, after twisting, sea-island textured yarns with twist and bulkiness are obtained, and then the sea-island textured yarns and high-shrinkage FDY yarns are fed into two rollers at a speed of 550m / min, and passed through two After the roller pulls, the island-shaped textured yarn enters the shaping hot box for heating and shaping. The heating and shaping temperature is 160°C. The high-shrinkage FDY wire is led to the lower part of the shaping hot box by an alumi...

Embodiment 2

[0028] The sea-island POY yarn with a specification of 130D / 24F and the high-shrinkage FDY yarn with a specification of 30D / 12F drawn out from the wire rack are introduced into the false twist texturing machine, and are fed into the false twist texturing machine at a speed of The first roller at 330m / min and the zero roller at a speed of 580m / min, among which the island-shaped POY yarn is sent to the deformation heating box for heating treatment after passing through the first roller. Twist the false twister of 6800r / min, obtain the sea-island textured yarn with twist and bulkiness after twisting, and then feed the sea-island textured yarn and the high-shrinkage FDY yarn into the second roller with a speed of 580m / min. After the roller pulls, the island-shaped textured yarn enters the shaping hot box for heating and shaping. The heating and shaping temperature is 160°C. The high-shrinkage FDY wire is led to the lower part of the shaping hot box by an aluminum tube, and then com...

Abstract

The invention relates to a high shrinkage sea-island filament and a production technology thereof. The production technology includes: drawing a sea-island POY filament and a high shrinkage FDY filament out of corresponding filament holders; completing the following processes on a table of a false twist texturing machine: 1) feeding the sea-island POY filament and the high shrinkage FDY filament drawn out of the filament holders into a first roller and a zero roller of the false twist texturing machine, wherein the sea-island POY filament enters a texturing hot box via the first roller to be heated, is cooled by a cooling plate, and is input to a false twister to be twisted; 2), feeding the twisted sea-island textured filament and the high shrinkage FDY filament into a second roller, wherein the sea-island textured filament enters a shaping hot box to be heated and shaped via the second roller, the high shrinkage FDY filament is guided to a lower part of the shaping hot box via an aluminum pipe, and then the high shrinkage FDY filament and the heated shaped sea-island filament are fed into a network spraying nozzle. The sea-island filament is high in breaking strength, will not be broken easily, and has high shrinkage performance, a good wool-like effect and a soft hand feeling.

Description

technical field [0001] The invention relates to the technical field of chemical fibers, in particular to a high-shrinkage island-in-the-sea yarn and a preparation process thereof. Background technique [0002] In recent years, the imitation suede fabric has been favored by consumers because of its soft, waxy and light texture. Generally, a single island-in-the-sea filament is used as a raw material for suede-like fabrics. After processing and sanding, fine and uniform fluff is formed on the surface of the finished fabric, thereby achieving the effect of imitating animal suede. However, this suede-like fabric is thin and not fluffy due to the raw material microfiber, and is easy to break and not wear-resistant after sanding, so that the entire production process efficiency is low and the defective rate is high, which is unfavorable for widespread promotion and use. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a high...
