Abstract
The invention discloses a cotton fabric high-efficiency dyeing and finishing process including modification treatment, scouring and dyeing in one bath, soaping, color fixation, post-finishing, drying, sizing, calendering, and coiling. Ultrasonic waves are used for pretreatment; at the same time, before a dyeing process, a fabric is subjected to low temperature plasma treatment, then the fiber fabric is subjected to modification treatment with 2,3-epoxypropyltrimethylammonium chloride and finally is treated by chitosan, and thus the fabric dyeing degree is increased, and the difficulty of the subsequent dyeing steps is reduced; with adopting of scouring and dyeing in one bath, the efficiency is increased, and the cost is reduced; in the dyeing process, a large amount of alkaline substances and inorganic salts are not used, natural dyes are used, and at the same time, a colophony powder is added as a color fixing agent, so that the color fixing effect is enhanced, besides, the environmental pollution is avoided, and the requirements of environmental protection are met; montmorillonite is used for flame retardant treatment on the fabric, so that the flame retardancy of the fabric is high; and with increase of anti-yellowing finishing, a final fabric does not easily turn yellow.
Description
Technical field
The present invention relates to a kind of efficient dyeing and finishing technology of COTTON FABRIC.
Background technology
Fiber is divided into chemical fibre and natural fabric, and 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.
Natural fabric refer to nature exist and growth, there is the fiber that weaving is worth, cotton fiber is a kind of natural fabric, moisture absorption and good permeability, soft and warming, is therefore widely used in field of textiles.
Cotton 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, cotton fabric 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.
