Problems solved by technology

Since the entire process is long and the fabric produced is essentially a brushed fabric, the high temperature, dyeing, sanding and shaping in each process must make the fabric enter different equipment for processing. , its surface wears a lot, resulting in low color fastness and reduced quality stability. After quality inspection, most of them need to be repaired, that is, they need to be re-dyed or sanded, and the repaired fabric further wears down the raw material itself , is a solution that does not solve the fundamental problem
The traditional production process also has problems such as long process, many links, poor color fastness, unstable quality, many repairs, low production efficiency, large fabric loss, and low economic benefits.
[0003] The existing improvement methods usually use a slightly lower temperature, lower the height of the sanding and other technical improvements, but due to the fixity of the raw material fabric itself, the improvement of the process has limited effect on solving the problem, so a new structure of nylon is needed on the market. spandex fabric

Embodiment

[0026] Below in conjunction with embodiment, the production process of the present invention is compared with original production process.

[0027] Selected fabric name: 220G / M270D / 68Ftactel / 2+30D Lycra spandex jersey surface carbon sanding

[0028] Production technology of the present invention and the contrast of former production technology are as follows:

[0029] original craft

[0030] Weaving fabric: large circular machine 34 inches 24G weaving

[0031] Blank high temperature presetting: 190℃, overfeed 20%, speed 20m / min

[0032] Stitching: Prevents uneven dyeing from curling of the selvedge

[0033] Dyeing: Nylon dyed with acid dyes at 98°C*40 minutes

[0034] Post-processing + color fixation

[0035] fixed dry

[0036] The carbon sanding is as follows: Machine: Mario crosta made in Italy

[0037] Sanding roller: 1.2.3.4 The difference between the sanding rollers is 5.5 / 6 / 6.3 / 6.2

[0038] Cloth output speed: 6 m / min

[0039] Tension: 50%

[0040] Main speed: ...

Abstract

The invention discloses a structure of a nylon polyurethane fiber sanding fabric and a production method thereof. The structure comprises a nylon polyurethane contact surface and is characterized in that the nylon polyurethane contact surface is an upper and lower double-layer structure, wherein a plurality of a nylon polyurethane fiber sanding circles are distributed on an external surface layer and are internal and external double-layer circle structures; and the production method comprises the steps of weaving, seaming and post-processing. The double-layer contact surface and the sanding circle structures are manufactured through the transformation of different stitches so that the fabric has good color fastness, stable quality and low repairing rate, and therefore, the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a surface structure of a textile fabric, in particular to a structure of a nylon spandex brushed fabric and a production method thereof. Background technique [0002] The production process of nylon spandex fabric is usually to pre-set the rough fabric at high temperature first, then dye it, and control the rebound stability and wearability of the fabric during the dyeing process. After the above process, the rough carbon sanding and sewing are carried out. Finally post-processing. Since the entire process is long and the fabric produced is essentially a brushed fabric, the high temperature, dyeing, sanding and shaping in each process must make the fabric enter different equipment for processing. , its surface wears a lot, resulting in low color fastness and reduced quality stability. After quality inspection, most of them need to be repaired, that is, they need to be re-dyed or sanded, and the repaired fabric further wears do...
