Technical Field

The invention relates to the technical field of jean fabric, in particular to a process for washing patterns on jeans by water.

Background

The water-washed jeans is an important process for manufacturing jeans. The function is that on one hand, the jeans can be softer and are convenient to wear; on the other hand, the jeans can be beautified, such as cat beard, horse rat, snowflake washing and the like. The trousers are different from the casual trousers, and the cloth of the jeans can be worn only by washing. The original jean is coated with a layer of sizing agent, if the jean is not washed, the jean is hard and uncomfortable to wear, and the jean also has influence on the body.

The jean washing patterns on the market are made by laser, patterns are formed after fading, the effect is good, but the manufacturing cost is high, the jean washing patterns are not suitable for small-batch production, and the jean washing patterns cannot be put into use in a large area.

Disclosure of Invention

s4: and (6) brushing glue. Brushing a layer of thin glue on the carved pattern, diluting the pattern by using latex according to the proportion of 5:1, and then drying the pattern in the shade, wherein the purpose of brushing the glue is mainly to form a thin protective layer on the surface of the pattern so that fine lines and small points in the pattern can be easily bonded with the fabric;

s5: and (6) pasting the graph. Fixing the finished jean fabric on a plane, then pasting the pattern, and removing the redundant part outside the pattern after the bonding is finished; the pasting method comprises the following steps: fixing one end of the adhesive tape, pulling the bottom surface of the adhesive tape from the lower side, and pulling a small adhesive tape to stick to a small point, wherein small lines and small points need to be completely fixed on the fabric;

s6: fading. The potassium permanganate is matched with the phosphoric acid, 40 g of potassium permanganate in one liter of water is added, 20 g of phosphoric acid is added and stirred uniformly, and the debugged potassium permanganate is sprayed uniformly and stably by a sprayer aiming at the surface needing to fade.
