Abstract

The invention relates to nylon sea-island microfiber leather fabric composite dye and application thereof. The dye is formed by combining acid dye and active dye. The application is as follows: at normal temperature, sequentially adding an acid level dyeing penetrating agent and composite dye to a dye bath, regulating pH value to 5-6, soaking a fabric in the dye bath, increasing temperature to 105-110 DEG C, preserving for 40-60min, and completely washing at 70-80 DEG C to obtain the dyed fabric; soaking the dyed fabric in a fixation bath, increasing temperature to 40-50 DEG C, preserving for 20-30min and washing. The composite dye formed by combining the acid dye and the active dye, is free from components violating against national technical standard for safety, can consistently dye poly urethane (PU) and nylon superfine fiber, and in particular can dye nylon microfiber leather. The composite dye is complete in chromatography, good in compatibility, synchronous to dye and easy to control quality.

Description

technical field [0001] The invention belongs to the field of composite dyes and applications, and in particular relates to composite dyes for nylon sea-island microfiber leather fabrics and applications. Background technique [0002] Sea-island microfiber leather (the product variety is mainly nylon sea-island microfiber leather) is the highest-grade product among "chemically coated leathers". Its texture and feel can be compared with high-grade natural leather. It has the inherent moisture absorption and breathability of natural leather, and it surpasses natural leather in terms of chemical resistance, waterproof, mildew resistance, and abrasion resistance. It is the current artificial leather field. New products at the highest technical level. [0003] Sea-island superfine fiber synthetic leather base fabric is complex. Since the nylon fiber used for the base fabric is superfine fiber, its dyeing performance is greatly different from that of conventional fibers, mainly in...
