Abstract
The invention discloses a dyeing and finishing process for polyamide fabric. The provided process comprises pretreatment, pre-setting, modified processing, dyeing, soaping, dye fixation, post-finishing, drying, setting, calendering and rolling. Supersonic waves are employed for pretreatment, fabric is subjected to low temperature plasma processing before the dyeing step, then 2,3-epoxy propyl trimethyl ammonium chloride is employed for modification processing of the fabric, the dyeing degree of the fabric is raised, and difficulty of the subsequent dyeing step is lowered. During the dyeing step, a lot of alkaline substances and inorganic salt are not used, natural dyes are employed, colophony powder is added as a dye-fixing agent, the dye-fixing effect is enhanced, environment pollution is avoided, and green environmental protection requirements are met. Montmorillonite is employed for modification processing and flame retardation processing of the fabric, and thus the flame retardation of the fabric is high. Anti-yellowing reagents are used both in the pre-setting and setting steps, and thus the final fabric is not easy to turn yellow.
Description
Technical field
The present invention relates to a kind of dyeing and finishing technology of nylon fabric.
Background technology
Fiber is divided into chemical fibre and natural fabric, natural fabric refer to nature exist and growth, have weaving be worth fiber, chemical fibre is raw material with the macromolecular compound of natural polymer or Prof. Du Yucang, through preparing the fiber with textile performance that the operations such as spinning solution, spinning and post processing obtain.Chemical fibre have fast light, wear-resisting, easily wash easily do, do not go rotten, the advantage such as not damaged by worms, be widely used in and manufacture clothing fabric, filter cloth, conveyer belt, rotary hose, rope, fishing net, electric insulated, medical suture, tyre cord and parachute etc.
Nylon fibre, is commonly called as nylon fiber, formal name used at school polyamide fiber, belongs to the one in chemical fibre, because it has extremely excellent wear-resisting, cold-resistant, ventilative, ageing-resistant performance.So be widely used in field of textiles.
Polyamide fibre is in dyeing course, in order to reduce environmental pollution, begin one's study at present and adopt natural dye to dye, but natural dye needs to dye at a lower temperature usually, and the Color of natural dye is poor, its fixing degree of the fabric dyed is lower, usually in dyeing course, a large amount of soda ash and inorganic salts are added in order to improve fixing degree, this brings larger difficulty to the treatment of dyeing wastewater of high salinity, ecological environment can be destroyed as directly discharged, cause the salinization of soil, use natural dye usually also can use some heavy metal ion as mordant simultaneously, do not meet the requirement of current ecological textile, and the coloured light of fabric becomes dim mostly after heavy metal ion mordant dyeing, affect vividness and the aesthetic property of DYED FABRICS.In order to reduce the dyeing difficulty of follow-up dyeing, usually need before dyeing to carry out preliminary treatment to fabric, but current preliminary treatment is all adopt the alkaline solution such as sodium hydrosulfite, sodium carbonate to carry out High Temperature Pre process substantially, larger to the damage of fiber.
