Description

Technical Field

[0001] The invention relates to the technical field of fabric processing, and in particular to a high color fastness nylon-ammonia cationic polyester mountaineering nylon fabric and a processing technology thereof. Background Art

[0002] Mountaineering fabric is suitable for outdoor sports, especially mountaineering. It is woven from nylon, polyester and spandex. It is light, breathable and not easy to wrinkle. It is widely used in work clothes, mountaineering fabrics, clothing, shoe materials and other fields. It has good shape retention, is light and comfortable, adapts to human activities, keeps human skin dry, and is suitable for various outdoor sportswear.

[0003] The nylon in this type of fabric is positively charged under acidic conditions, and is generally dyed with acid dyes using the electrostatic adsorption of acid groups and positively charged amino groups and the hydrogen bond between the dye and nylon; while polyester can be dyed with cationic dyes. Modified polyester contains sulfonate anion groups and is suitable for dyeing with cationic dyes. However, there are three main dyeing methods for acid dyes and cationic dyes:

[0004] (1) Two-bath method: that is, first dye the cationic dyeable polyester fiber, then wash and fix the color at room temperature, and then overdye the nylon fiber. The disadvantages of this method are: not only is the production cycle long, requiring twice the dyeing time, but the production efficiency is low, especially because there is an additional washing and fixing process, which wastes energy and resources.

[0005] (2) One-bath one-step method: The pre-treated fabric is immersed in a dye solution containing cationic dyes and acid dyes, first heated to 60℃~80℃ for a period of time and then heated to 110℃~120℃ for dyeing. This method is suitable for light color dyeing, and the color fastness can reach level 4, but the color fastness and depth of dark colors are not up to standard.

[0006] (3) One-bath two-step method: first add auxiliaries and acid dyes, heat to 98℃-100℃ to complete the dyeing of nylon, then cool to 600℃~70℃, add dispersants and cationic dyes, heat to 100℃~105℃ to complete the dyeing of cationic polyester. This method is suitable for dark colors, and the color fastness cannot reach level 4-5. It is required to dye nylon with acid first and then cationic polyester. Otherwise, the apparent depth of cationic polyester is not good and color spots are prone to appear. Summary of the invention

[0007] The invention aims to provide a nylon-ammonia cationic polyester mountain nylon fabric with high color fastness and a processing technology thereof, so as to achieve dyeing with cationic dyes and acid dyes in the same bath and improve color fastness and apparent depth.

[0015] S6. Shaping and finishing: Shaping temperature 165℃-175℃, shaping speed 25m / min-35m / min, air volume 1300CFM-1500CFM, overfeed 6%-8%.

[0016] Preferably, the first nylon-spandex hollow yarn and the second nylon-spandex hollow yarn are both N70D / 48F FD DTY+40OP, and the cationic dyeable modified polyester is P300D / 96F SD DTY.

[0017] Preferably, the material tank in step S2 contains 55g / L-60g / L caustic soda, 15g / L-20g / L desizing agent TF-127, 18g / L-22g / L refined emulsifier TF-120C, and 4g / L-6g / L penetrant TF-JFC.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The invention adopts the first nylon-spandex hollow-covered yarn as the warp yarn, the second nylon-spandex hollow-covered yarn as the A weft yarn, and the cationic dye-dyeable modified polyester as the B weft yarn to weave the nylon-spandex cationic polyester grey cloth, and performs the same-bath dyeing after the pre-treatment such as desizing, firstly uses the nylon blocking agent to temporarily block the ionized amino group of the nylon, then adds the leveling agent, the non-ionic cationic polyester dyeing auxiliary agent and the cationic dye, adjusts the pH value of the dye bath to 4-5 suitable for the dyeing of the nylon and the cationic polyester, then controls the dyeing temperature rise curve, allows the cationic dye to be kept warm at 90±2°C to complete the dyeing, and does not cool down after the cationic polyester dyeing, but adds the non-ionic dispersant WA and the cationic dye to dye the cationic polyester. After the anionic diffusant NNO is added, the acid dye is added after running for a period of time, so that the cationic dye adsorbed by the cationic polyester can further penetrate, diffuse and dye. At the same time, the excess cationic dye in the dye bath is ion-bonded with the anionic diffusant NNO and dispersed and suspended in the dye bath without settling on the fabric surface. At the same time, it also avoids the phenomenon of adsorption and agglomeration of cationic dyes after the acid dye is added later, ensuring that the acid dye can be combined with nylon for dyeing. The desorbed nylon sealer is also dispersed and suspended in the dye bath under the action of the non-ionic dispersant WA, so as to obtain a nylon-ammonia cationic polyester mountaineering nylon fabric with high fastness and large apparent depth after soaping.
