Denim clothing printing pattern technology
1. Traditional printing: Traditional printing also refers to printing and dyeing. It refers to the general term of dyeing, printing, finishing, washing and other technological processes. Sometimes called dyeing and finishing, it is a processing method of textiles. Printed denim clothing appeared in the striped printed denim uniforms of train conductors in the 1940s. In the 1950s, Levi’s used colorful “Aloha” Hawaiian patterns to print on sports and leisure clothing. Hand-painted jeans in the 1970s became popular at the time. In a moment of craze, traditional printed denim has evolved and followed today.
2. Hand printing: The commonly used hand printing includes letterpress printing and hollow printing. Letterpress printing refers to the use of stencils to engrave patterns, and the use of yin and yang surfaces to rub on denim fabrics to form patterns. Hollow board printing is also called stencil printing, which refers to the use of stencils of different materials to engrave hollow patterns and scrape and paint the hollow areas on the fabric. Compared with industrial printing methods, the efficiency is low, the output is low, and the quality is uneven. In the industrialized production mode, manual printing is more to reflect its uniqueness, creativity and artistic charm.
3. Hand-painted: The use of textile dyes or acrylic paints to create paintings on denim clothing is also an expression of the personality of young people today. Mainly according to the application of brushes or different tools, use outline, flat coating, splashing and other brush strokes to draw decorative effects on the finished denim clothing, forming a unique denim clothing. The penetration of textile dyes is better than that of acrylic paints, and the touch feeling on the fabric is better after drying. Hand-painted denim garments can be directly painted by hand after finishing, which avoids damage to the color vividness of the pattern after finishing. CaineLondon launched a series of TruckerJacket created with graffiti, tattoos, and iconic icons from the 1990s. The full-page hand-painted decoration of the back with a combination of figures and floral letters is used to highlight the bright colors. The fashion designers used popular, young, and interesting patterns to combine with denim clothing, reflecting the rebellious, independent, and free spirit of hippies in the 70s, continuing the classics, playing with creativity, and gradually transforming the cynical style of cowboys into Display of personality tags.

Dyeing and engraving: Dyeing and engraving refers to adding white powder or strong bleaching agent that destroys the background color on the surface of the dyed denim fabric, and then printing on the surface of the dyed denim fabric. The effect of blue background and white flowers produced by drying, steaming, water washing and other processes. When the bleaching agent does not react with the background color, adding other colors to the dye can print a color pattern on the indigo cloth. This printing method is called color discharge.
5. Paint overprinting: refers to the use of color paste with a good ratio, the use of rotary screen or flat screen to print the pattern on the denim fabric. The coating has good coverage, the surface of the fabric is flat, and it is not absorbed by the fabric. It is applied to the frictionless part of the denim jacket. Among them, there are more full-page overprints on the back. It is not suitable for application on thin, soft or fluffy fabrics.

Dior 2015 men’s wear imitating graffiti-style striped color printing, making the pattern more vivid and agile.
6. Transfer printing: Transfer printing refers to printing dispersible dyes on special paper or reusable substrates, using different methods such as hot pressing to transfer patterns to denim fabrics.
7. Flocking printing: After printing the adhesive paste of the desired pattern on the denim fabric, electrostatic flocking is performed, and finally post-processing. This type of printing requires a strong adhesive to ensure that the short suede and denim fabric are firm. The combination. Denim clothes give people the feeling of civilians with strong colors, not suitable for heavy makeup, but the flocking printing technique is mostly used in high-end denim clothes, and the patterns are mostly retro European style and rattan flowers. Its advantages: the fabric has a strong sense of three-dimensional concavity and convexity, the pattern has a stepped sense of layering, and the hand feels soft. Disadvantages are: the production volume is small, it is not suitable for scrubbing and rubbing excessively, and the flower pattern design should not be complicated and overemphasized.
8. Bad print: On the basis of the traditional burnt-out process, use burnt-out pulp to rotten cotton on the denim fabric, and then finish it after washing, etc. to form an alternative style of denim clothing with a three-dimensional effect of de-threading. The white weft yarns of the burnt-out part are scattered, and the warp and weft yarns of the pattern part are not damaged to form a three-dimensional carved plant pattern. This kind of printing design technique has destructive aesthetics, and is not suitable for application on knitted denim, that is, denim fabric woven by loops.
9. Foam printing: Print a printing paste composed of thermoplastic resin and foaming agent on denim fabric, and form a three-dimensional embossed pattern after high temperature vapor evaporation foaming treatment. The edge of the denim fabric pattern of foam printing is more difficult to handle, and it is mostly used in cartoon or letter patterns.
10. Digital printing: refers to the use of inkjet or reactive dyes to print computer-processed patterns on denim fabrics to form vivid artistic patterns. The formation method is very different from the traditional flat screen and rotary screen printing method. Modern denim printing patterns pay more attention to individualization and customized production. Traditional floral and animal patterns have gradually been out of focus. People are more inclined to light psychedelic and abstract patterns. Such rapidly changing popular elements have caused unpredictable market changes. However, digital printing satisfies the small-batch, multi-variable production model, which makes denim printed apparel a surprising success. The grotesque and rebellious VivienneWestwoodRedLabel brand uses abstract jungle elements and digitally printed denim skirts to show the brand’s unruly style. Utilize the tough texture of denim and the feminine and feminine printed skirts to connect with each other.
11. Laser laser printing: refers to the pattern effect formed by burning the yarn and vaporized dye on the surface of the denim fabric through computer image processing. Denim fabrics are mostly used for the treatment of cat whiskers, monkeys, tearing, distressing, washing and other decorative effects. Compared with the traditional handmade production such as spraying potassium permanganate, laser production reduces the discharge of water pollution and the cumbersome processing process Link. The laser printing pattern is clear, and various artistic style patterns can be printed on the fabric. Compared with the plane and two-dimensional patterns formed by traditional printing, the laser-forming pattern has a stronger three-dimensional effect and a more varied style; but its working principle is different. Restrictions lead to only the formation of dark and light denim background effects. Compared with traditional printed denim, its advantages are faster in processing speed, simple in operation, efficient and environmentally friendly.
