Description

A kind of natural dye dyeing and finishing technology of dacron

Technical field

The present invention relates to a kind of natural dye dyeing and finishing technology of dacron.

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.

Terylene is an important component part of chemical fibre, due to the physicochemical property of terylene self, dyeing terylene adopts disperse dyeing usually, in order to ensure that Color is good, usual employing high temperature and high pressure method dyeing, but DISPERSE DYES has certain contaminative to environment, high temperature and high pressure method dyeing is simultaneously high to equipment requirement, and energy consumption is large.In order to reduce environmental pollution, beginning one's study at present and adopting natural dye to dye, simultaneously due to the performance of natural dye self, usually dyeing at a lower temperature, 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.

3, the present invention is in dyeing process, do not use a large amount of alkaline matters and inorganic salts, have employed natural dye, avoid environmental pollution, meet the requirement of environmental protection, add dye leveller and bleeding agent, diffusant, equalization is improved, add imvite in dyeing course, play fire retardation; Simultaneously in whole dyeing course, temperature is no more than 90 DEG C, and compared to High Temperature High Pressure in the past, lower to equipment requirement, energy consumption is less;

4, the present invention is in dyeing process, strictly controls intensification rate of temperature fall, and dyeing time, and fabric is dyeed, and firmness is high, even dyeing, dye stability are good;

5, the present invention adds color fixing process after dyeing, have employed the natural color-fixing agent colophony powder of environmental protection, avoid environmental pollution, further increase the fixing degree of dacron in color fixing process; What adopt before fixation soaps in technique, have employed lauryl sodium sulfate, polyvinylpyrrolidone and AEO-9 carries out composite, anti-staining, removal floating color are effective, make soap poststaining fabric color fastness to washing, colour fastness to rubbing simultaneously, especially fastness to wet rubbing all significantly strengthens, and also reduces simultaneously; Carry out going mordant process to fabric before technique of soaping, employing oxalic acid aqueous solution can get rid of the mordant that fabric adheres in dyeing course well completely, thus avoid environmental pollution, ensure that attractive in appearance, the vividness of fabric color, and oxalic acid belongs to organic monoacid, lower to human injury;

6, present invention adds postfinishing process, 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;

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.
