Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
A dyeing and finishing process of cotton fabric comprises the following steps: a, placing an original cotton blank on a singeing machine, and controlling the flame temperature of the singeing machine within a certain range to enable the original cotton blank to move in flame for singeing treatment; step B, padding the singed cotton blank in bleaching liquid for 3-5 hours at room temperature, then steaming the padded cotton fabric, and finally washing the steamed cotton fabric with water; step C, placing the cotton fabric obtained in the step B into a caustic soda solution to be soaked for 30-70 min; step D, preparing pigment printing paste, wherein the pigment printing paste is prepared according to the following formula by weight: 10-30% of water-insoluble color pigment, 10-16% of fabric adhesive, 5-10% of filler, 3-5% of dispersant, 3-6% of chitosan, 0.2-3% of pH regulator, 4-9% of cross-linking agent, 4-8% of thickening agent and the balance of water; c, performing pigment printing on the cotton fabric obtained in the step C by using the pigment printing color paste; e, steaming and soaping the cotton fabric obtained in the step D; and F, washing the cotton fabric obtained in the step E by warm water, and then drying by hot air.
The invention is illustrated below by means of specific steps:
and step 10, matching the original blanks, distinguishing the front sides and the back sides of the two pieces of cloth, enabling the front sides of the two pieces of cloth to be located on the same side surface, and splicing the two pieces of cloth into an integral blank. In this step, the number of the original blanks is not limited, that is, the number of the original blanks may be multiple.
And 20, singeing the original blank to improve the smoothness of the original blank. Specifically, the connected raw blank is placed on a singeing machine, the singeing machine is started to enable the connected blank to move rapidly, and the flame of the singeing machine singes the fluff on the raw blank. The blank after singeing treatment improves the smoothness of the original blank and reduces the fluff on the original blank, and the treatment of the process can effectively reduce the hair falling phenomenon during the subsequent treatment of the blank.
In the step, the temperature of the singeing flame is controlled to be between 350 and 370 degrees, if the singeing temperature is too high, the blank is easy to ignite, and if the singeing temperature is too low, the singeing quality is affected, and the phenomenon that fluff is not burnt cleanly occurs. If the fluff is not burnt completely, color spots appear during dyeing, and the quality of the cloth is reduced.
And step 30, desizing and bleaching the blank processed in the step 20, wherein desizing aims to remove size on the blank and ensure the water absorption performance of the produced cotton fabric. The bleaching aims to remove pigments on blanks, improve the whiteness of the blanks and ensure the color vividness of dyeing or printing.
In the step, the bleaching agent used for blank bleaching is a mixed solution of hydrogen peroxide bleaching, caustic soda and a stabilizer, and the purpose of selecting hydrogen peroxide instead of sodium hypochlorite as the bleaching agent is mainly to protect the environment. The hydrogen peroxide bleaching solution applicable to the embodiment has the hydrogen peroxide content of 2-6g/L, caustic soda is added to adjust the pH value to 10-11, and a proper amount of stabilizer is added to ensure the stability of the hydrogen peroxide bleaching solution. When bleaching, firstly padding the blank in bleaching liquid at room temperature, then steaming at 95-100 ℃ for 45-60min, and finally washing the bleached blank with water.
And step 40, drying and cooling the bleached blank, treating the blank with a caustic soda solution at room temperature, placing the blank into the caustic soda solution, soaking for 30-70min, and improving the stability of the blank and reducing the shrinkage rate of the fabric by using the blank treated by the caustic soda solution. After the treatment of the caustic soda solution, the crystal area of the blank fiber is reduced, the amorphous area is increased, the later-stage dye can conveniently enter the inside of the fiber, the dyeing degree is improved by about 20 percent, and the brightness is increased.
Step 50, preparing pigment printing paste, wherein the pigment printing paste is prepared according to the following formula by weight: 10-30% of water-insoluble color pigment, 10-16% of fabric adhesive, 5-10% of filler, 3-5% of dispersant, 3-6% of chitosan, 0.2-3% of pH regulator, 4-9% of cross-linking agent, 4-8% of thickening agent and the balance of water; the bleached blank is dyed by using the pigment printing paste by using pigment printing equipment, and a firm, transparent and wear-resistant colored film is formed on the fabric to obtain the cotton fabric.
In this embodiment, the device for printing the blank is not limited, and can perform rotary screen or flat screen printing to obtain fabrics of different shapes.
In the embodiment, the pigment printing has the advantages of simplicity in use and convenience in process, and the printed fabric has the advantages of high sun-proof degree and clear outline lines, so that the stereoscopic impression of the patterns of dark-colored bottom and light-colored florets can be guaranteed.
And step 60, baking the obtained cotton fabric. And the baking is to perform low-temperature steam treatment on the obtained cotton fabric at the temperature of 100-.
And step 70, finishing the baked fabric under high pressure or high temperature, and flattening the surface of the fabric or rolling patterns on the surface of the fabric through physical plasticity under the high temperature or high pressure condition so as to increase the luster of the fabric. The fabric has special luster, the brightness of the fabric is improved, and the fabric has good and smooth drape.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
