Abstract
The invention provides a method of dyeing an acrylic fiber/hair/copper ammonia fiber blended knitting fabric by use of a one-bath two-stage process. The dyeing method is characterized by technically comprising the following steps: (1) pre-treating; (2) dyeing acrylic fiber/hair/copper ammonia fiber; (3) neutralizing; (4) soaping; (5) performing color fixation. Various dyes and assistants are placed in a same dye bath, and the temperature and pH value of the dye bath are changed in different dyeing periods of time, so that cationic dyes, weak acid dyes and active dyes meet the optimal dyeing condition to dye various fibers in different properties at the same time, thereby simplifying the production step, improving the production efficiency, improving the utilization ratio and the dyeing quality of the dyes, and meanwhile, further saving a lot of water resources, reducing the discharge of sewage so as to facilitate environmental conservation.
Description
Technical field
The present invention relates to the colouring method of textiles, particularly a kind of acrylic fibers/hair/copper ammonia fiber blended knitted fabric one is bathed the method for two-stage method dyeing.
Background technology
Along with the enhancing of human society to environmental protection and awareness of saving energy, people more and more pay attention to exploitation and the research to environmental protection, energy-conservation, high efficiency products.Concerning consuming energy, pollute all more serious dyeing, become the developing direction of current dyeing and finishing processing by improving process exploitation textiles energy-conservation, efficient, environmental protection.Traditional two bath process, has not only caused the waste of water resource, also exists operation more simultaneously, and technical process is longer, waste time and energy etc. not enough, and secondary dyeing causes painted inhomogeneously sometimes, easily causes defective product, and production efficiency is low, and blowdown flow rate is large.For addressing the above problem, people have developed the method for one-bath dyeing, as Chinese patent " one-pass bath method for dyeing " (publication number CN 1032965A) discloses a kind of single bath process for the dyeing of polyester-cotton blend viscosity mixed yarn; Chinese patent " method of one-bath dyeing " (publication number CN 1538004A) discloses the method for the BLENDED FABRIC one-bath dyeing of a kind of cotton and other fibers material etc., but many research did not all relate to the method for acrylic fibers, hair, copper ammonia fiber blended knitted fabric one-bath dyeing.
Tradition purified cotton yarns price significantly goes up, and the approval of consumer to fiber product mostly now, acrylic fibers, hair, copper ammonia fiber blended knit product increase substantially, very popular, still, by acrylic fibers, hair, three kinds of raw material one-bath dyeings of different nature of copper ammonia fibre, tend to attend to one thing and lose sight of another, make the utilization rate of dyestuff low, dyeing quality is poor, and process technology difficulty is very large.Therefore, study a kind of method of acrylic fibers, hair, copper ammonia fiber blended knitted fabric one-bath dyeing, this is current the art technical problem urgently to be resolved hurrily.

Above-described embodiment 1, in 2, described degreaser is the acidproof of German Glen Housman company, resistant to elevated temperatures KP nonionic degreaser, described anti-settling agent is the CN anti-settling agent of Clariant company of Switzerland, described levelling agent is the KOP-12S levelling agent of Shanghai great Xiang company, described glacial acetic acid (HAC) is Heilungkiang Daqing Oilfield Company product, the acid of described neutralization use is the glacial acetic acid of Jiangsu Suo Pu company, described soaping agent is the soaping agent of German De Sida company, in described color fixing process, adopt the acidic color fixing agent of Clariant company of Switzerland, described cation dyes are that German De Sida company produces, weak acid dye is the two peach dyestuff public properties in Qingdao, described cleaning agent is the AS-P anion cleaning agent of Japanese chemical company, described REACTIVE DYES is the REACTIVE DYES of Japanese chemical drug company, described glauber salt is the glauber salt of Sichuan mount emei Yun Pai company, the soda ash of the Qingdao Jian Ye company that described alkali lye adopts is made into.
Adopt levelling agent to have good level dyeing effect to acrylic fibers, hair, copper ammonia fibre, there is competing dying in levelling agent and dyestuff, along with the rising of temperature, cation dyes replace gradually function acrylic fibers, weak acid dye and replace gradually the levelling agent on hair, thereby reach the object of level dyeing.
The REACTIVE DYES adopting, in the time that copper ammonia fibre is dyeed, is to borrow basic species to regulate pH value to reach 10.5-11.5, makes dyestuff and fiber reach covalent bond and play tint retention.Described alkali is adding fashionablely, repeatedly add in batches, too fast to prevent dying fixation in copper ammonia fibre, causes pattern; Avoid nitrile, wool fibre to sustain damage in the time that dyeing temperature raises simultaneously.
Dyeing main points of the present invention:
(1) because cation dyes and weak acid dye are cationic, REACTIVE DYES is anionic property, therefore, zwitterion reaction when avoiding dyeing, strictly reinforced in order when reinforced, add in advance precipitation preventing agent, prevent cation dyes, weak acid dye, REACTIVE DYES reaction.
(2) strengthening demineralized water operation, four time periods of the every natural gift of demineralized water (7:30,13:00,18:00,00:00) test, guarantees that water quality is constant, and the water hardness is controlled in 50PPM.
(3) because grey cloth used is acrylic fibers, hair, copper ammonia fibre knitted fabric; copper ammonia fibre is met water; particularly when high temperature; brute force sharply declines; easy fracture causes knitted fabric to disconnect, and especially, in the time of acrylic fibers, frosted glass temperature, more easily disconnects; it is now acrylic fibers, the fastest moment of Mao Shangran; once shutdown joint, also can cause acrylic fibers, hair pattern, therefore; every batch of joint adopts cylinder joint; broken hole on charge level is repaired in time, and the joint that enters cylinder adopts knotting to connect, inhyibit wire rope socket; in cylinder, keep clean, smooth, adopt messenger to enter cylinder.
(4) adjust dye vat nozzle exit pressure and rotating speed, prevent because of nozzle exit pressure excessively, grey cloth is upset and stirred instead, avoid constructing in irrational dye vat and dyeing at equipment.
(5) whole one-bath process process, last fastness depends on last soaping, therefore, in the time soaping, the soaping agent using will be suitable for low temperature and to acrylic fibers, hair, the copper ammonia fibre effect of soaping.
(6) to select acrylic fibers, hair impact minimum, to the color-fixing agent that every fastness is good and look tails off of copper ammonia fibre.
The above, be only preferred embodiment of the present invention, is not the restriction of the present invention being made to other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present invention, still belong to the protection domain of technical solution of the present invention.
