Abstract

The invention discloses a polyamide fabric modifying, dyeing and finishing process. The process comprises the steps of pretreatment, pre-setting, modification treatment, dyeing, soaping, color fixing, after treatment, drying, setting, calendering and rolling. Helicase and alpha-amylase are adopted for carrying out pretreatment, mixed liquor of nanometer titanium dioxide, gamma-(2, 3-epoxypropoxy) trimethoxypropylsilane and caprolactam is adopted for modifying performance of polyamide fabric fundamentally, and the dye-uptake rate of the fabric is increased; in the dyeing working procedure, a large number of alkaline substances and inorganic salts are not used, a leveling agent and a dispersing agent are added, and dyeing levelness is improved; meanwhile, as rosin powder is added to serve as a color fixing agent, the color fixing effect is enhanced, environmental pollution is avoided, and the requirement for environmental protection is met; moreover, montmorillonite is adopted for carrying out modifying and flame retarding on the fabric, and therefore the fire retarding property of the fabric is high; anti-yellowing reagents are used in the presetting and setting steps, and therefore the final fabric is not prone to yellowing.

Description

A kind of modification dyeing and finishing technology of nylon fabric

Technical field

The present invention relates to a kind of modification 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, belong to the one in chemical fibre, its product good springiness, intensity is high, wear-resisting, durable, density is little, not easily damage by worms, and is subject to liking of consumers in general, is widely used in the fields such as dress ornament, fishing gear and national defence space flight.

Nylon fibre fabric, in dyeing, adopts ACID DYES usually.But it is strong that the molecular structure of ACID DYES determines its hydrophobicity, therefore in dyeing course dye-uptake and level-dyeing property poor, the solubility of especially acid weld is very little, be difficult under normal temperature dissolve completely, but with cotton-shaped suspension in the solution, and with comparatively jogging speed sedimentation, cause each regional concentration of dye liquor different, and the upper dye temperature of nylon dyeing is lower, therefore easily cause look flower.

Meanwhile, nylon fibre fabric in dyeing, in order to ensure dyeing quality, just usually need fabric is carried out to concise, washing, dehydration, dries, dyes after heat treatment.But complex procedures like this, efficiency is lower, and energy consumption is higher.Usually the alkaline solution such as sodium hydrosulfite, sodium carbonate is adopted to carry out high-temperature process when while is concise, larger to the damage of fiber.

In addition, nylon fibre fabric, in dyeing course, adds a large amount of soda ash and inorganic salts usually in order to improve fixing degree in dyeing course, and this brings larger difficulty to the treatment of dyeing wastewater of high salinity, can ecological environment be destroyed as directly discharged, causing the salinization of soil.
