Abstract
The invention discloses a dyeing and finishing process for modal fabric. The process comprises the procedures of pretreatment, pre-setting, modification treatment, dyeing, soaping, fixation, after-finishing, drying, sizing, calendering and rolling. According to the invention, pretreatment is carried out by adopting ultrasonic wave, and a step of modification treatment is added; in the dyeing procedure, a base substituent SA is used, use of a large quantity of alkaline substances and inorganic salt is avoided, nature dye is adopted, and colophony powder is added as a fixing agent, so that the color fixing effect is enhanced, environmental pollution is avoided, and the requirement of green environmental protection is met; furthermore, montmorillonoid is adopted to carry out modification treatment and flame retardant treatment on the fabric, so that the flame retardancy of the fabric is high. According to the invention, a yellowing-resisting reagent is used in the procedures of pre-setting, sizing and after-finishing, so that the final fabric cannot become yellow easily.
Description
Technical field
The present invention relates to a kind of dyeing and finishing technology of modal 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.
Model is a kind of artificial chemical fibre, and Modal fibre meets the requirement of ECO-TEX standard, to physiological harmlessness and can biodegradation.For the textiles of direct physical contact, it has special advantage, and fine count fiber give knitted fabric comfortable wear performance, soft feel, the pendency sense of flowing, charming gloss and high-hygroscopicity.Therefore field of textiles is widely used in.
Model 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.
