Description

Technical Field

[0001] The invention relates to the technical field of blue printed cloth production, in particular to a complex color anti-dyeing pulp for blue printed cloth and a preparation method thereof. Background Art

[0002] Blue printed cloth was originally called "flower-watering cloth" and was called "medicine-spotted cloth" in the Song Dynasty. It has a history of more than 1,300 years. It originated in the Qin and Han Dynasties, flourished in the Tang and Song Dynasties, and was widely popular among the people during the Ming and Qing Dynasties. As an important part of traditional Chinese folk art, blue printed cloth is unique in traditional Chinese folk art with its unique craftsmanship and simple cultural charm. Blue printed cloth is widely used in making daily clothes, quilt covers, mosquito nets, pillowcases, wrapping cloth and other daily necessities. It not only has practical value, but also has high artistic and aesthetic value. As an intangible cultural heritage, the inheritance and development of blue printed cloth has received widespread attention from all walks of life.

[0003] Traditional blue printed fabrics are blue and white, which are elegant and beautiful, and are loved by consumers. Therefore, blue and white have become the inherent characteristics of blue printed fabrics. However, with the development of the times, consumers have more demands for the colors of blue printed fabrics. They hope that blue printed fabrics can add new colors while maintaining the traditional blue and white colors, so that the patterns of blue printed fabrics can be more layered, thereby increasing its artistic expression.

[0004] Anti-dyeing paste is a special paste that prevents dyes from staining and forming patterns during the fabric printing and dyeing process. Anti-dyeing paste is made by printing a resist agent on the fabric to prevent dyes from staining, and then dyeing the fabric so that the area printed with the resist agent can prevent dye penetration, thereby forming a specific pattern. This printing process is called resist printing, which includes two types: anti-white printing and color-resist printing. Anti-white printing refers to printing white patterns with a printing paste containing a resist agent, while color-resist printing refers to adding dyes or pigments that are not affected by the resist agent to the resist printing paste to print colored patterns.

[0005] Anti-dyeing slurry is a key material in the production process of blue printed cloth, and its performance directly affects the final quality of blue printed cloth. Traditional anti-dyeing slurry is mainly made of lime and soybean flour in a certain proportion. It is easily affected by air humidity, has a low adhesion rate, and becomes hard after drying. This leads to a long processing time for blue printed cloth, easy shedding of the finished product, and low comfort.

[0006] Therefore, it is of great practical significance to provide a complex color anti-dyeing paste for blue printed cloth with high adhesion rate and good finished product quality. Summary of the invention

[0007] The object of the present invention is to provide a complex anti-dyeing pulp for blue printed cloth and a preparation method thereof, aiming to solve the technical problems in the prior art such as low adhesion rate of the anti-dyeing pulp, hardening after drying, etc., as well as long processing time of blue printed cloth, poor quality of finished product and low comfort.

[0008] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0009] The present invention provides a complex color resist dyeing slurry for blue printed cloth, comprising the following components in parts by weight:

[0010] 30-40 parts of emulsified paraffin, 20-30 parts of quicklime, 20-30 parts of tofu, 5-8 parts of calcium phosphate, 5-10 parts of locust bean gum, 2-5 parts of phenylhydrazine p-sulfonic acid, 1-3 parts of silicone, 5-15 parts of polyvinyl alcohol and 1-3 parts of penetrant.

[0011] Furthermore, the penetrant is sodium alkyl sulfonate and sodium alkylbenzene sulfonate.

[0012] Furthermore, the mass ratio of the sodium alkyl sulfonate to the sodium alkylbenzene sulfonate is 1:1.

[0013] The present invention also provides a method for preparing the complex color resist dyeing slurry for blue printed cloth described in the above technical solution, which is characterized by comprising the following steps:

[0014] Mixing tofu and quicklime, and mashing them to obtain a first mixture;

[0015] performing a first fermentation on the first mixture to obtain a fermented first mixture;

[0016] adding calcium phosphate, locust bean gum, phenylhydrazine p-sulfonic acid, silicone, polyvinyl alcohol and an osmotic agent to the fermented first mixture, performing a second mixing, and further pulverizing to obtain a second mixture;

[0017] The second mixture is subjected to a second fermentation, and then emulsified paraffin is added and mixed to obtain the complex color anti-dyeing pulp for blue printed cloth.

[0018] Furthermore, the particle size of the first mixture is 10 to 15 mm.

[0019] Furthermore, the conditions of the first fermentation are: temperature of 25-30° C. and time of 3-5 hours.

[0020] Furthermore, the second mixing time is 1 to 2 hours.

[0021] Furthermore, the particle size of the second mixture is 5 to 8 mm.

[0022] Furthermore, the conditions of the second fermentation are: temperature of 25-30° C. and time of 2-3 hours.

[0023] The present invention also provides the use of the complex color anti-dyeing pulp for blue printed cloth described in the above technical solution or the complex color anti-dyeing pulp obtained by the preparation method described in the above technical solution in the production of blue printed cloth.

[0024] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0025] (1) The complex color anti-dyeing slurry for blue printed cloth of the present invention uses quicklime and tofu as the main components of the anti-dyeing slurry, and the viscosity of the complex color anti-dyeing slurry is increased by adding locust bean gum and polyvinyl alcohol, thereby improving the bonding force between the anti-dyeing slurry and the cloth, thereby improving the adhesion rate of the anti-dyeing slurry and improving the use effect;

[0026] (2) The present invention also adds organic silicon as a softener, which can reduce the dynamic and static friction coefficients of the fiber, reduce the friction resistance between fibers and between fibers and the human body, make the fabric softer and more comfortable, and the resulting fabric has higher quality;

[0027] (3) The present invention further adds phenylhydrazine parasulfonic acid and a penetrant. Phenylhydrazine parasulfonic acid can avoid uneven dyeing, while the penetrant can improve the permeability of the anti-dyeing slurry, making it adhere to the fabric more evenly, thereby improving the use effect and making the resulting fabric better in quality.

[0028] (4) The present invention also adds emulsified paraffin, which can separate the dyeing material from the fabric fibers after the anti-dyeing slurry is applied to the fabric, thereby achieving the anti-dyeing technical effect in a physical and chemical combination with other ingredients.
