Brief Introduction Of Five Printing Processes For Knitted Underwear Silk Screen

< p > 1. pattern trial < /p >

< p > pattern design should not only pay attention to continuous patterns, individual patterns and duplicated samples, but also describe the suitable styles and specifications of garments, < a href= "http://www.91se91.com/news/" > fabric > /a > types and colors, and draw directions on the direction and position of patterns, specify the pattern number, number of colors, designers and dates.

< /p >

< p > continuous pattern < /p >

< p > continuous patterns are commonly used in two party continuous or Quartet continuum. The contents of the trial are the integrity of the pattern unit, the accuracy of the pattern joint length, the uniformity of the pattern arrangement, the importance of the color and color on the fabric, and the effect of pattern and printing.

< /p >

< p > single pattern < /p >

< p > single pattern is an independent unit with no continuity around it.

The trial content of individual patterns includes the integrity of the pattern structure, the adaptability of the pattern and garment, the correctness of the characters, the reproducibility of pattern and color on the fabric, and the effect of pattern and printing.

< /p >

< p > copy > /p >.

< p > because most of the guest samples can not be used directly, for example, ready-made garments, cloth samples, photographs, duplicating patterns, printing pictures and diagrams, etc., most of them can not be used directly in plate making. When processing and finishing the pattern replicas for trial reproduction, it is necessary to analyze the samples and requirements of the customers first, and see whether the replica samples are consistent with the customer requirements and printing conditions.

< p > 2. silk screen < a href= "http://www.91se91.com/news/index_c.asp" > printing < /a > plate design < /p >

< p > (1) the choice of screen type should be determined according to the fineness and area of the pattern, the type of the printed fabric and the consistency of the paste.

Fine patterns are larger in size, larger in size, larger in size, larger in size, and smaller in size.

Pigment printing knitted underwear generally chooses 40 mesh 80 purpose silk screen.

< /p >

< p > the general pattern is made of silk screen mesh, parallel to the plate and frame parallel to the two color patterns, or adjacent to the horizontal straight line with higher precision. The wire mesh angle is better, which is conducive to uniform screen tension.

< /p >

< p > (2) in recent years, the photosensitive adhesive used in the screen printing plate of China's knitted underwear industry is developing from the backward nylon photosensitive glue and gelatin lacquer to the use of diazo type photosensitive adhesive.

The diazo type photosensitive adhesive has the advantages of innocuity, no pollution, slow dark reaction, and can be operated in a semi darkroom, and has the advantages of easy operation.

There are two kinds of solvent resistant and water resistant.

Because the pigment paste is water type, the water resistant diazo photosensitive adhesive is chosen for the screen printing of knitted underwear.

The process of plate making is as follows: < /p >

< p > the photosensitive adhesive is coated with a photosensitive adhesive, drying the manuscript, exposing, developing the plate, drying and retouching the two exposure.

< /p >

< p > (3) to numbered each printing plate and arrange the order of the printed page number, usually according to the order of "color separation and tracing" in the pattern, in the process design book, we should also explain the relationship between the name of the printed pattern and the printed fabric.

< /p >

< p > (4) the length and width of the printed pattern on the garment piece is the maximum size of the pattern printing in the length and width of the garment piece plus 3-5 centimeters.

< /p >

< p > (5) the direction and position of the pattern on the printed page are determined according to the direction and position of the pattern on the printed fabric and the printed fabric on the printing platen.

The direction and position of the pattern on the printed page must be schematic.

< /p >

< p > 3. < a href= "http://www.91se91.com" > pigment printing < /a > color paste formula design < /p >

< p > the design method of printing paste has two kinds: color selection and color matching.

Pigment printing paste mainly consists of coating, binder crosslinking agent and thickening agent.

Recently, many colouring agents are used to mix pigment paste with binder and paste.

The proportion of each cost varies according to the different materials used in knitted underwear.

< /p >

< p > 4. printing process design < /p >

< p > > a href= "http://www.91se91.com" > knitted underwear < /a > the design of printing process should pay attention to the following aspects: < /p >

< p > fabric color > /p >

< p > according to the design intention of the pattern, when the color changes of a pattern are changed, the printing process sheet can be filled out with the printing paste number or the color printing paste used in each printing plate.

< /p >

< p > printing sequence is the order of printing paste, determined by the relationship between the structure and color of the pattern.

As far as possible, arrange the color paste with color matching as near as possible. The higher cost color paste is arranged as far as possible before, and the large area pattern is printed on the edge of the fabric as far as possible.

< /p >

< p > when the garment is printed, the position of the pattern pattern on the garment is determined by the position of the pattern on the garment, and then determined according to the shrinkage rate of the fabric after printing and the tailoring process conditions.

< /p >

< p > 5. special printing < /p >

Silk printing special printing of "P" > a href= "http://www.91se91.com" > underwear < /a > has increased the added value and appreciation value of the fabric, and enriched and beautifed the people's life.

It has all kinds of foam printing, discoloration printing, photoluminescent printing, electrochemical aluminum pfer printing, electrostatic flocking pfer printing, color halftone printing and so on.

These special printing processes have similarities and differences with general screen printing.

For example, the operation of electro chemical aluminum pfer printing and electrostatic flocking printing is basically similar to ordinary printing, but only by heating and pressing pfer process.

Other special prints are different or more than one process.
