Description
Technical Field
The invention belongs to the field of dyeing methods of high-strength nylon 6 fabrics, and particularly relates to a dyeing method for improving the dyeing performance of a high-strength nylon 6 fabric.
Background
The nylon 6 fabric has the advantages of high tensile strength, light weight, smooth hand feeling, wearing comfort and the like, and has good application prospect in the fields of civil textiles and advanced luxury goods. By 2018, the annual output of the nylon 6 slices in China is over 400 ten thousand tons, and the nylon 6 slices still show a rapid growth trend. However, in order to further improve the strength and wear resistance of nylon 6 fabric and expand the application range thereof, high-strength nylon 6 has been produced as a functional derivative thereof. The high-strength nylon 6 fabric is a fabric woven by high-strength and high-modulus high-strength nylon 6 fibers. The high-strength nylon 6 fiber is the nylon 6 fiber with higher strength obtained by performing multistage drafting on a melt-extruded high-viscosity polymer and improving the orientation degree of a fiber molecular chain. Therefore, the high-strength nylon 6 usually has higher orientation degree and crystallinity, but the functional characteristic causes the problems of lower dye uptake, uneven dyeing, lower color fastness and the like of the fabric product, and the application of the high-strength nylon 6 fabric is severely restricted. Therefore, the development of a technology for improving the dyeing properties such as dye uptake, level dyeing property, color fastness and the like of the high-strength nylon 6 fabric is very urgent.
Currently, the commonly used nylon 6 fabric dyes are acid dyes, in particular weakly acidic dyes. The required dyeing environment is mild, and the pH value of the dye solution cannot be too low, so that the influence on the mechanical property of the fabric is small. In addition, the acid dye has complete chromatogram, bright color and rapid dyeing, and the dyeing residual liquid has no heavy metal residue and has less environmental pollution. As patent CN104711874A discloses a dyeing process of ordinary nylon fiber, which comprises: pretreatment, presetting, dyeing, soaping, color fixation, after finishing, drying, setting, calendering and rolling. In the dyeing process, disperse dye and acid dye are used for dyeing, so that the dyeing effect is improved; a soaping and color fixing process is added, and a green environment-friendly aldehyde-free TCD-R is adopted in the color fixing process, so that the firmness of the fiber is greatly improved; finally, the color fastness and the softness of the fabric are further improved by adopting an after-finishing process. However, the pretreatment process adopted by the process has higher temperature, more auxiliary agents are used, and the requirement on the later-stage wastewater treatment process is higher. Meanwhile, compared with nylon 6 fabric, the high-strength nylon 6 fabric with high orientation degree and crystallinity degree requires higher and more complex dyeing process. Therefore, it is very important to develop a relatively simple and efficient dyeing technique for high-strength nylon 6.
