Problems solved by technology

[0004] In the application of high-end fashion brands, due to the lack of thermal stability of nylon itself and poor dyeability, the dyeing of nylon fabrics often suffers from side-to-side color difference, and the color fastness barely meets the national standard for textiles, and cannot stably reach the national first-class textiles. product standard

Embodiment approach

[0028] As a preferred embodiment of the present invention, the pre-shrinking process is specifically:

[0029] The fabric tissue is placed in NaOH lye, and pre-shrinked at 80°C for 90 minutes at a low temperature. The NaOH lye is made of 30% NaOH liquid lye and water, and the amount of NaOH lye is 15% owf.

[0030] As a preferred embodiment of the present invention, during the pre-setting process, the setting temperature is controlled to be 200° C., with a positive overfeed of 5-10%.

[0031] As a preferred embodiment of the present invention, the compounding process is specifically:

[0032] Put the fabric tissue in the compounding solution added with detergent and diffusing agent, control the temperature at 100°C, and carry out the compounding process at 45°C.

[0033] As a preferred embodiment of the present invention, during the dyeing process, the dyeing bath ratio is controlled to be 1:20, the pH is 4-5, the water used in the dye is softened and reaches the softened wat...

Embodiment 1

[0039] A dyeing and finishing method for strengthening the high color fastness of nylon four-way stretch fabrics. After weaving warp yarns and weft yarns made of nylon elastic core-spun yarns into fabric fabrics, pre-shrinking, pre-setting, compounding, dyeing, and one-time Rewashing, drying, secondary rewashing and styling treatment are completed.

[0040] The warp and weft yarns described in this embodiment all use 30D nylon elastic core-spun yarn.

[0041] In this embodiment, the pre-shrinking process is specifically:

Abstract

The invention relates to a dyeing and finishing method for enhancing the high color fastness of nylon four-way stretch fabrics. After weaving warp yarns and weft yarns made of nylon elastic core-spun yarns into fabric fabrics, preshrinking, presetting, compounding, and Dyeing, one-time rewashing, drying, second rewashing and styling treatment are completed. Compared with the prior art, the dyed and finished fabrics of the present invention have high color fastness, can control dye migration to the greatest extent, and the color difference between the sides of dark fabrics can be stabilized within the third grade of the national textile standard. The fabrics are elastic and soft, and the finished product The fabric is of high quality.

Description

technical field [0001] The invention relates to a fabric dyeing and finishing method, in particular to a dyeing and finishing method for enhancing the high color fastness of nylon four-way stretch fabric. Background technique [0002] With the improvement of living standards, people's needs for various daily necessities are becoming more and more diversified. Cloth is not limited to the function of covering the body and avoiding the cold. The second is to have better quality and functional requirements, especially to reflect In terms of fashion style and wearing comfort. [0003] Compared with polyester, nylon fabric has better moisture absorption than polyester, so it is comfortable to wear. On the other hand, nylon has a lower coefficient of friction, so it has better wear resistance and a smoother hand feel than polyester. However, the color fastness of nylon four-way stretch fabric is poor, which is a major shortcoming restricting the application of clothing. Previousl...
