Abstract
The invention discloses a method for dyeing cotton loose fibers by using indigo dye, which comprises the steps of reducing the indigo dye and fibers by using caustic soda and sodium hydrosulfite as dry cylinders according to the weight ratio of 1: 5-30, dyeing, cleaning, oxidizing, dyeing for multiple times according to different color shades to reach the depth required by the color, and then cleaning, soap boiling, oxidizing and softening. The indigo dye is used for dyeing cotton loose fibers to obtain indigo cotton, cotton sliver or cotton roll loose fibers.
Description
Technical field
The invention relates to a kind of colouring method of bulk cotton fibres, more particularly about a kind of method that bulk cotton fibres is dyeed with indigo dye.
Background technology
Coat is because of good water absorption in the all-cotton knitting, and gas permeability is strong, and is antistatic, easily decontamination, and the quality softness, fashionable whole international market, existing cotton sportswear more is subjected to people's favor, the process of after stain makes but the many employings of commercially available knitwear are knitted earlier; Thereby the color dullness, designs and varieties are few, and technical process is longer, and cotton is spun into a yarn through the cotton mill, and the reeled yarn that completes again just can go dyeing, and dying needs again fall a yarn for weaving cotton cloth or doing knitwear and use reeled yarn after good.It is more to repeat operation back and forth, time-consuming, require great effort, cause unnecessary waste, and easily causes defective product when yarn-dyed, piece dyeing.
A kind of colouring method of bulk cotton fibres is disclosed in Chinese patent CN-91112719, but disclosed in this patent be the method that dyes with reducing dye.
A kind of colouring method of bulk cotton fibres is disclosed in Chinese patent application CN-00103414, but disclosed in this patent be the method that dyes with REACTIVE DYES.
The method that is to use REACTIVE DYES and reducing dye to dye of above-mentioned binomial patent disclosure, different fully with the application, and also be the present application people's invention.
Up to now, dyeing is not found out the method that the use indigo dye of a practicality dyes to bulk cotton fibres.
Summary of the invention
The purpose of this invention is to provide a kind of method of using indigo dye that bulk cotton fibres is dyeed.
Two of purpose of the present invention provides a kind of use indigo dye to the bulk cotton fibres resulting product that dyes.
Of the present invention this will and be described and further embody with other purposes by following detailed description.
In the present invention,, comprise the steps: the method that bulk cotton fibres dyes with indigo dye
A, by the weight ratio of dyestuff and fiber 1: 5～30 indigo dye is done stock vatting with caustic soda, sodium hydrosulfite earlier, temperature is 50～60 ℃, is reduced into yellow solution in 20～35 minutes, pours the dye vat that is added with auxiliary agent in advance into;
B, bulk cotton fibres dyed 30～50 minutes in the time of 20～40 ℃, hung out cleaning, and oxidation according to being of different shades, is repeatedly dyeed, and reached the needed degree of depth of color, cleaned then.
Further, of the present invention with indigo dye to the method that bulk cotton fibres dyes, comprise the steps:
A, by the weight ratio of dyestuff and fiber 1: 5～30 indigo dye is done stock vatting with caustic soda, sodium hydrosulfite earlier, temperature is 50～60 ℃, is reduced into yellow solution in 25～30 minutes, pours the dye vat that is added with auxiliary agent in advance into;
B, bulk cotton fibres dyed 35～45 minutes in the time of 30～40 ℃, hung out cleaning, and oxidation according to being of different shades, is repeatedly dyeed, and reached the needed degree of depth of color, cleaned then.
Be preferably, of the present invention with indigo dye to the method that bulk cotton fibres dyes, comprise the steps:
A, by the weight ratio of dyestuff and fiber 1: 5～25 indigo dye is done stock vatting with caustic soda, sodium hydrosulfite earlier, temperature is 50～60 ℃, is reduced into yellow solution in 30 minutes, pours the dye vat that is added with auxiliary agent in advance into;
B, bulk cotton fibres dyed 40 minutes in the time of 30～40 ℃, hung out cleaning, and oxidation according to being of different shades, is repeatedly dyeed, and reached the needed degree of depth of color, cleaned then.
In the method for the invention, except that comprising above step, also comprise the steps:
C, be neutral, carry out pickling 10～20 minutes then, be heated to 90～100 ℃, soap boiling oxidation 10～20 minutes with glacial acetic acid regulator solution pH value;
D, add 2% sodium perborate and 4% washing agent LS then, be heated to 100 ℃, soap boiling 15 minutes, wash, be cooled to 50 ℃, add softener CWS and handled 10 minutes in 55 ℃.
Further, in the method for the invention, except that comprising above step, also comprise the steps:
C, be neutral, washed then 15 minutes, be heated to 95～100 ℃, soap boiling oxidation 15～20 minutes with glacial acetic acid regulator solution pH value;
D, add 2% sodium perborate and 4% washing agent LS then, be heated to 100 ℃, soap boiling 15 minutes, wash, be cooled to 50 ℃, add softener CWS and handled 10 minutes in 55 ℃.
In the method that bulk cotton fibres is dyeed with indigo dye of the present invention, described auxiliary formula is: caustic soda: 20～30 grams per liters, sodium hydrosulfite 10～20 grams per liters, bleeding agent 0.5～1 grams per liter.
Further, in the method that bulk cotton fibres is dyeed with indigo dye of the present invention, described auxiliary formula is: caustic soda: 25～30 grams per liters, sodium hydrosulfite 15～20 grams per liters, bleeding agent 0.5～1 grams per liter.
Be preferably, in the method that bulk cotton fibres is dyeed with indigo dye of the present invention, described auxiliary formula is: caustic soda: 25～28 grams per liters, sodium hydrosulfite 14～16 grams per liters, bleeding agent 0.5～1 grams per liter.
With the method that indigo dye of the present invention dyes to bulk cotton fibres, can obtain cotton, sliver or the lap bulk fibre of indigo look.
Of the present invention to the bulk cotton fibres processing method, the process that traditional elder generation's spinning is dyeed again develops into the process of directly processing with bulk cotton fibres, and the horn of plenty people's lives provide the more clothes and the garment material of multi-color kind.
The present invention is compared with prior art: it does not need special equipment just can produce, therefore the suitable especially small enterprise of the method produces, the cotton cylinder difference of the look that this method is produced is little, coloured light is pure, soft, bulk, basically solved loose colour, fade and staining, cotton knot, problems such as COLOR FASTNESS, traditional after stain cotton spinning of spinning is earlier changed over and dyes the back spinning process earlier, also changed simultaneously traditional pure asterism melange cloth, can weave and only contain 5%～15% and 60%～80% a high proportion of melange cloth, reach with natural public cotton and be made into the performance that fabric has, but cost is much lower, can add designs and varieties and produce bright and colourful knitted underwear or garment material as raw material, but also can reduce yarn-dyed, the piece dyeing defective product, improve the feel of finished product, reduced and returned yarn, winder multiple tracks technology, reduce cost, shorten the process-cycle, look cotton loss improves the utilization rate of cotton than I, and very big economic benefit and social benefit are arranged.
Below further specify the present invention by specific embodiment, but embodiment only be used for the explanation, can not limit the scope of the invention, in the present invention, refer in particular to as non-, all amounts, part, percentage are unit of weight.
