Discussion on the application of silk printing in clothing design

the application of silk printing in clothing design is different for different types of applicable industries. It should be reflected in the printing process. Silk printing can make ordinary T-shirts show intuitive artistry, reflect the wearer's spiritual outlook, taste, interest and personality, and flexibly express the designer's design creativity, which is deeply loved by consumers and designers. This paper mainly takes the application of silk printing in knitted T-shirt printing and eye tone color printing of textiles as an example

I. Introduction to the process of silk printing

silk screen printing flower is a printing method in which silk is made into a flower plate, which is covered on the textile during printing, and the printing paste is added on the flower plate, which is printed on the textile under the extrusion of the scraper, so that the textile can obtain the pattern. This method has the advantages of simple plate making, unrestricted pattern and low cost. Silk screen printing flowers, no matter which industry they are used in, use silk of different materials as the carrier of the plate film, but there are some differences in the selection of silk and the plate making process

1 prepress processing

prepress processing includes pattern design and drawing black-and-white color separation draft (i.e. positive film). Generally, continuous shooting process is used for photosensitive plate making, and water-resistant photosensitive materials are required for plate making

2 silk material

silk material is the main material of printing. The silk woven with silk has long been replaced by nylon silk. Although nylon silk has high strength, wear resistance and elasticity, it is easy to be affected by temperature and humidity changes and has great flexibility, which affects the accuracy of printing. Therefore, polyester (polyester) silk is widely used in printing high-end products

in addition, metal wires are also used, such as nickel for round printing and stainless steel wire for circuit boards. There are many kinds of silk specifications, with a width of 90 ~ 230cm and a mesh of 31 ~ 196 mesh/cm, which can be selected according to different uses

3 silk printing equipment

silk printing equipment is very complex, and there is a big gap from simple family manual workshops to modern complete sets of equipment. Textile silk printing can be divided into round and flat. Flat equipment includes printing table, automatic flat printing machine and rotary table printing machine. Among them, the maximum width of the automatic leveling machine is 3.2m, the length is about 60m, and the maximum chromaticity is 24 colors, which belongs to large-scale equipment

textile printing is generally continuous printing, even handkerchiefs and tablecloths with independent patterns are cut after continuous printing, while clothing pieces and shirts are mostly rotary printing

4 material difference

the difference of printing materials is simply the difference between water and solvent (oily). Textile printing is generally dominated by dyes, especially on silk textiles, corresponding dye technology and supporting equipment need to be adopted according to the properties of different fibers. The process and supporting equipment are relatively complex. Pigment printing paste is used as the printing material for printing, which is called water-based ink by some people

due to the need of practicality, the color and luster of textile silk printing must have a certain firmness (not easy to fade). At the same time, due to the large change of color and luster, the size and color should generally be sold and stored separately, and the printing paste should be prepared according to the requirements when used

in addition, there are many special functional pigment printing pastes, such as foaming ink, bright ink, fluorescent ink, etc. they are often not limited by the properties of textile fibers, so they occupy a certain position in pigment screen printing flowers. In recent years, the variety of printing inks is also increasing

5 post press processing

in the textile silk printing process, post press processing is very important. It must be steamed or baked at high temperature for color fixation, so that the dye and textile fiber new company will become a complete solution provider of polyketone composites from concept development to commercialization, so as to ensure color fastness. In addition, after fixing the color, wash it with water to remove the sum of the two and the unfixed dye in the printing paste, so as to make the color bright

it should be noted that even if the coating process is adopted, it should be baked at high temperature, but it can not be washed. The post press processing of non textiles is generally relatively simple, but some necessary treatments should also be taken according to the quality requirements of printed products, such as UV ink curing treatment

II. Silk printing flowers of knitted T-shirts

silk printing paint directly prints knitted T-shirts, which can be completed as long as they are naturally dried or baked. Because the process does not need wet treatment, it is especially suitable for knitted clothing pieces, which can avoid the deformation of knitted textiles due to wet treatment. This process is applied to the production of small batch, multi variety and multi color products

1. sample processing

pattern design should not only pay attention to continuous patterns, individual patterns and duplicate patterns, but also explain the appropriate clothing style and specification, textile type and color, and draw a schematic diagram of the direction and position of the pattern on the clothing, indicating the pattern number, chromatic number, designer and date, etc

(1) continuous pattern

continuous pattern is usually two-way continuous or four-way continuous. Its trial contents include the integrity of pattern units, the accuracy of pattern joint length, the uniformity of pattern arrangement, the importance of pattern color on textiles, and the effect of pattern and printing

(2) separate pattern

separate pattern is an independent individual unit with the surrounding. The trial contents of individual patterns include the integrity of pattern structure, the adaptability of the combination of patterns and clothing, the correctness of words, the reproducibility of pattern color on textiles, and the effect of patterns and printing

(3) duplicate samples

because most of the customer supplied samples cannot be used directly, such as ready-made clothes, cloth samples, photos, copy paper samples, printed pictures and schematic diagrams, most of them cannot be used directly for plate making, and patterns must be copied after processing. When reviewing the duplicate samples, first analyze the customer supplied samples and required conditions to see whether the duplicate samples are consistent with the customer's requirements and printing process conditions. Pay attention to whether the joints of the continuous samples can be connected continuously and the patterns are uniform. When the patterns have obvious physical changes, whether to restore the samples after proper finishing
