Abstract
The invention discloses an environmental-friendly dyeing and finishing process of a real silk fabric. The environmental-friendly dyeing and finishing process of the real silk fabric comprises pretreatment, presetting, cryogenic freezing treatment, dyeing, mordant removal, soaping, color fixing, post-finishing, drying, setting, calendering and winding. By performing pretreatment with helicase and alpha-amylase and by adopting cryogenic freezing treatment before dyeing, the performance of the real silk fabric is fundamentally modified and the dye uptake rate of the fabric is improved; a great amount of alkali substances and inorganic salt are not used in the dyeing process and leveling agent and dispersing agent are added, the dyeing uniformity is improved, the environmental pollution is avoided by using natural dyes and the requirements on the environmental protection are satisfied; since self-cleaning treatment is added during post-treatment, the self-cleaning ability, the wrinkling resistance and the water washing fastness of the fabric are improved; the entire process is environmental-friendly and pollution-free.
Description
Technical field
The present invention relates to a kind of environment-friendly type dyeing and finishing technology of real silk fabric.
Background technology
Fiber is divided into chemical fibre and natural fabric, chemical fibre has fast light, wear-resisting, easily wash easily dry, 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 treatment suture, tyre cord and parachute etc., natural fabric refer to nature exist and growth, there is the fiber that weaving is worth, chemical fibre is raw material with the macromolecular compound of natural polymer or Prof. Du Yucang, through preparing spinning solution, the fiber of what the operation such as spinning and post processing obtained have textile performance.
Real silk just belongs to a kind of natural fabric, and definite says it is a kind of natural protein fibre, because it has good moisture absorption, permeability, has the performances such as skin-protection and health-care effect, is therefore also widely used in clothing and manufactures field of textiles.
Traditional dyeing all adopts chemical dye to dye usually, but the pollution of chemical dye to environment is larger, in order to reduce environmental pollution, begin one's study at present and adopt natural dye to dye, and usually dye at a lower temperature when adopting natural dye to dye, also just lower to the requirement of equipment like this, energy consumption also can reduce.
But 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, can ecological environment be destroyed as directly discharged, causing the salinization of soil.Use natural dye usually also can use some mordants containing metal ion simultaneously; although the use of mordant can improve Color; if but mordant can not be removed completely in post processing; not only can bring pollution to environment; the coloured light of fabric also can be made simultaneously mostly to become dim, affect vividness and the aesthetic property of DYED FABRICS.In addition, 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.Simultaneously; usually can notice in current fabric post-treatment operation that flexibility arranges; but otherwise arrangement is ignored; the automatically cleaning ability of such as fabric; if fabric has automatically cleaning ability; so its clean aspect after polluting again can be easier, can avoid adopting strong dirt-removing agent carry out decontamination or long-time immersion and make the life-span of fabric impaired.

6, present invention adds Final finishing science and engineering skill, improve the performances such as the crease and shrink resistance performance of fabric, COLOR FASTNESS, pliability, uviolresistance, antibiotic property, resistance combustion; Simultaneously in arrangement process, when multiple finishing agent mixing, the various finishing agent selected is while playing respective effect, and can also play the effect strengthened mutually, cooperative effect is good; Select imvite as fire retardant, add quaternary ammonium salt simultaneously and modification is carried out to imvite, make flame retardant effect better, non-environmental-pollution; In addition, in finishing process, add self-cleaning finishing, first ionomer process is carried out to fabric, then adopts TiO
2/ SiO
2the hydrosol processes, and reaches the automatically cleaning ability that improve fabric, also improve its water-fastness firmness, and its wrinkle resistance is also further enhanced simultaneously, which greatly enhances the service life of fabric and overall combination property;
7, the present invention all employ the yellow reagent of resistance in pre-setting, sizing, makes final fabric be not easy to turn yellow;
8, the present invention have employed calendering process further, makes the bright and clean smooth of fabric, can improve feel further, makes feel more soft fluffy, ensures that washing shrinkage meets the demands simultaneously;
9, the temperature of several operation such as preliminary treatment of the present invention, dyeing, sizing is relatively more steady, and such process conditions jumping characteristic is less, and technics comparing is steady, makes the final performance of fabric more stable;
10, efficient, the environmental protection of dyeing of the present invention, technique are simple, and simple operation, can promote the use of.
