Description
Technical field
The present invention relates to blended yarn woven fabric staining technique field, relate in particular to the co-bathing dyeing method of a kind of acrylic fibers and viscose glue (cotton) fiber.
Background technology
Traditional nitrile sticking (nitrile is cotton) production is all that minute two one bath two-step methods are produced, and during production, first dyes acrylic fiber and dyes viscose glue (cotton) fiber again or first dye viscose glue (cotton) fiber after stain acrylic fiber.There is following problem in this two one bath two-step method dyeings:
The one,, it is long that minute two one bath two-step methods are carried out the dyeing time, has partially long shortcoming of production cycle, but also waste energy very much, seriously restricts the raising of production efficiency, so need to improve.
The 2nd,, two one bath two-step method dyeings are complicated, brought a lot of troubles for technical staff author, have affected the stable control of production technology, cause unstable product quality, and technical risk is larger.And coarse due to the easy pilling of overlong time fabric, feel, can greatly reduce like this comfortableness of fabric, limited the Application Areas of product.
The 3rd,, because the process time is long, flow process is many, causes a large amount of sewage effluents, and the dyeing cost increases, and cost of sewage disposal increases, and gives national integrated environment build-up of pressure.
Summary of the invention
Technical problem to be solved by this invention is: for the deficiency that prior art exists, provide that a kind of production technology is simple, technology controlling and process stable, save the acrylic fibers of the energy and the co-bathing dyeing method of viscose glue (cotton) fiber.
For solving the problems of the technologies described above, technical scheme of the present invention is:
The co-bathing dyeing method of acrylic fibers and viscose glue (cotton) fiber comprises the following steps,
(1) co-bathing dyeing pre-treatment:
By weight proportion acrylic fibers and viscose glue (cotton) fiber blend yarn are made into knit fabric;
(2) co-bathing dyeing:
Knit fabric described in step (1) is entered overflow dyeing machine, add water, then order adds chelating agent 8108 and pH value mediator agent AC-608, be warming up to again 30-50 ℃, add cation dyes after running 5-10min, add REACTIVE DYES after running 10-20min, add glauber salt after running 10-20min, speed with 1-1.5 ℃/min after running 10-20min is warmed up to 95-98 ℃, enter the interchanger cooling after running 30-50min, after cooling to 40-60 ℃, water is drained, then add the hot water washing 10-20min of 50-70 ℃, rear knit fabric obtains dyeing;
(3) co-bathing dyeing post processing:
Knit fabric after dyeing described in step (2) is entered in normal-temperature water, order adds acid scouring agent DM-1531 and dispersant DM-1501, then be warming up to 60-80 ℃, running 10-30min, advance cold water, draining after overflow, temperature are down to 20-30 ℃, then obtain product after adding cold water washing 5-10min.
Sticking (cotton) fabric CATION (acidity) REACTIVE DYES of nitrile (neutral or alkalescence) co-bathing dyeing.Dying acrylic fibers on cation dyes must need sour environment, must need neutrality or alkaline environment and dye sticking (cotton) on REACTIVE DYES.
As a kind of scheme, in step (1), the mass ratio of the described acrylic fibers in described knit fabric and viscose glue (cotton) fiber is 1:1, is labeled as A50/R(C) 50.
As a kind of scheme, in step (2), described cation dyes are that the SD type is celebrated in Japanese chemical drug ED type or Shanghai, and described cation dyes consumption accounts for the 0.5-1.5% of described knit fabric weight.
As a kind of scheme, in step (2), described REACTIVE DYES is Japanese chemical drug CN type, and described REACTIVE DYES consumption accounts for the 0.5-1.0% of described knit fabric weight.
As a kind of scheme, in step (2),
The concentration of described chelating agent 8108 is the 0.5-1 grams per liter;
The concentration of described pH value mediator agent AC-608 is the 0.5-1.5 grams per liter;

As a kind of preferred scheme, in step (2), after adding pH value mediator agent AC-608, the pH of working solution is between 6-8.As preferred scheme, the pH of working solution is between 6.71-7.07.
Owing to having adopted technique scheme, the invention has the beneficial effects as follows:
The co-bathing dyeing method of acrylic fibers provided by the invention and viscose glue (cotton) fiber, realized that whole dyeing environment had both satisfied positive sour environment (between 6-7) when dying acrylic fibers on the dyestuff, satisfy again direct dyestuff alkaline environment alive (between 7-8), also realized the technological innovation of zwitterion one-bath dyeing production without precipitation simultaneously.This method shortens the process time greatly, has improved output, and that has reduced water, electricity, vapour can consumption, thereby has reduced cost.The present invention has not only brought economic benefit to enterprise, and has brought environmental effect to society, owing to having reduced quantity of wastewater effluent, is conducive to environmental protection.Because the technological process of production shortens, also reduced direct labor's labour intensity.And reduced blowdown flow rate, directly country and mankind's environmental protection are contributed.Owing to having shortened production procedure, just improved production efficiency accordingly, improved product quality.In addition, make the fabric feel better because dyeing time shortens, and reduce the pilling effect, improved the product serviceability.
Adopt the pH value to test for the working solution of 4.0-12.0, obtain the fabric bursting strength under different pH values, shown in table specific as follows:
As can be known, fabric is that after 8.0 working solution is processed, bursting strength is best through the pH value from upper table, and working solution pH value is increased to 8.0 by 4.0, and the cloth bursting strength improves gradually, and working solution pH value is increased to 12.0 by 8.0, and the cloth bursting strength reduces gradually.And almost free of losses of fiber in we dye pH6.71-7.07 value scope.
