Problems solved by technology

[0002] Printing is one of the dyeing methods of textiles. Synthetic pigments, adhesives and thickeners are generally used to prepare printing pastes, such as the Chinese publication "Printing and Dyeing", published in 2005, and the title of the article is "Cotton Fabric Pigment Printing". The literature introduces the pigment printing technology, screens out some pigment printing pastes and supporting auxiliary products, and the supporting auxiliary products include adhesives, thickeners and ammonia water. The hand feeling of products printed with these pigment pastes and supporting additives Good, good fastness, the disadvantage is that with the increasingly severe environmental protection situation, the preparation and use of synthetic pigments will cause certain environmental pollution
The disadvantage is that the petroleum ether used in the extractant has a kerosene smell and is irritating to the eyes, mucous membranes and respiratory tract
The disadvantage is that acetone is extremely flammable and explosive, slightly irritating and slightly toxic, and can be absorbed by the respiratory tract, digestive tract, and skin, endangering human health

Embodiment 1

[0011] Mix the red pepper skin powder with a particle size of 100nm, the binder UDT, and the thickener at a ratio of 7%, 92.5%, and 0.5% by mass percentage, and mix them under the condition that the ambient temperature is 27°C. First stir in the mixer at a speed of 180r / min for 22min, stir it evenly, then stir at a speed of 850r / min for 55min, let stand, and form a printing paste.

Embodiment 2

[0013] Mix the red pepper skin powder with a particle size of 150nm, the binder UDT, and the thickener at a ratio of 9%, 90%, and 1% by mass percentage, and mix them under the condition that the ambient temperature is 28°C. Stir in the mixer at a speed of 230r / min for 17min, stir it evenly, then stir at a speed of 950r / min for 45min, let it stand, and form a printing paste.

Embodiment 3

[0015] Mix the red pepper peel powder with a particle size of 200nm, the binder UDT, and the thickener at a ratio of 11%, 87%, and 2% by mass percentage, and mix them under the condition that the ambient temperature is 29°C. First stir in the mixer at a speed of 280r / min for 12min, then stir it evenly, then stir at a speed of 1050r / min for 35min, and let it stand to form a printing paste.

[0016] Table 1 Apparent depth and fastness of printed fabrics

[0017]

[0018] As can be seen from Table 1, using colored red pepper peel powder instead of synthetic pigments can give printed fabrics full color without any pollution to the environment. With the increase of the mass percentage of red pepper peel powder in the printing paste, the apparent depth of the printed fabric gradually increases, and the dry and wet rubbing fastness are good, both above grade 3.

Abstract

The invention relates to a preparation method of red pepper skin powder printing paste and belongs to the technical field of textile printing and dyeing. The preparation method adopts red pepper skinpowder for replacing the traditional pigment and preparing the printing paste, mixing the red pepper skin powder with particle size of 100-200nm, an adhesive UDT and a thickening agent in mass percents 7-11%, 87-92.5% and 0.5-2% respectively, then stirring for 12-22 minutes at a rotating speed of 180-280r / min in a stirring machine under the condition that an ambient temperature is 27-29 DEG C, uniformly stirring, then stirring for 35-55 minutes at a rotating speed of 850-1050r / min, and standing, so that the printing paste is formed. The preparation method provided by the invention has the advantages that the red pepper skin powder is utilized for preparing the printing paste, technology is simple, operation is easy, and the paste is full and bright in color. By adopting the prepared red pepper skin powder printing paste for printing a fabric, the printed pattern is clear in contour, printing fastness is good, and the problem of pollution caused by use of pigment is solved.
