Printing Method For Fabric Knowledge Introduction

< p > 1, directly < a href= "//www.sjfzxm.com/news/" > printing < /a > /p >

< p > direct printing is printed directly on white fabric or pre dyed fabric.

The latter is called cover printing.

Of course, the color of the printed pattern is much deeper than that of the dyed base.

A large number of common printing methods are direct printing.

< /p >

< p > if the fabric is white or mostly white, and the printed pattern looks lighter from the back, then we can judge that it is a direct printed fabric. (Note: because of the strong penetration of printing paste, the light fabric can not be judged according to this method).

< /p >

< p > if the fabric is of the same depth and shade, and the printing pattern is much deeper than the background, then this is the cover printing fabric.

< /p >

< p > two, discharge printing < /p >

< p > > a href= "//www.sjfzxm.com/news/index_c.asp" > discharge printing < /a > through two steps, the first step is to dye the fabric into a single color, and second steps to print the pattern on the fabric.

< /p >

The printing paste in < p > second contains strong bleaching agent which destroys the underlying dyestuff, so this method can produce the blue bottom white dot pattern cloth, which is called white discharge.

When the bleach is mixed with the dye which does not react with it in the same color paste (vat dyes belong to this type), it can be used for color printing.

Therefore, when a suitable yellow dye (such as vat dyes) is mixed with a bleaching agent, a yellow dot pattern can be printed on the blue bottom fabric.

< /p >

< p > because the background color of discharge printing is first dyed with a piece dyeing method. If the base color is printed on the floor, the color of the background is much richer and much deeper.

This is the main purpose of discharge printing.

< /p >

< p > discharge printing fabric can be printed through roller printing and screen printing, but it can not be printed by heat pfer printing.

As compared with direct printing, the cost of printing and printing fabrics is very high. It is also necessary to be careful and precise in controlling the use of reducing agents.

The fabric printed in this way is better in sale and higher in price.

Sometimes, the reductant used in this process will cause damage or damage to the fabric at the printed pattern.

< /p >

< p > if the color of the two sides of the fabric is uniform (because it is stained), and the pattern is white or different from the base color, it will be confirmed that discharge printing is < a href= "//www.sjfzxm.com" > fabric > /a >; careful examination of the reverse side of the pattern will reveal the traces of the original background (the reason for this phenomenon is that the chemical agent that destroys the dye can not penetrate completely to the reverse side of the fabric).

< /p >

< p > three, resist printing < /p >.

< p > anti staining printing includes two stages: < /p >

< p > (1) printing chemical or wax resin that can prevent or prevent dye penetration into fabric on white fabric; < /p >

< p > (2) dyed fabric.

The purpose is to dye the base color to create a white pattern.

Note that the result is the same as that of discharge printing fabric, but the way to achieve this result is contrary to discharge printing.

< /p >

< p > the application of anti staining printing method is not universal. It is usually used only when the background color can not be discharged.

Compared with the large-scale production base, most resist printing is realized by means of handicraft or manual printing, such as wax resist printing.

< /p >

< p > because discharge printing and resist printing produce the same printing effect, so it is often not identified by naked eye.

< /p >

< p > four, pigment printing < /p >

< p > the use of paints instead of dyestuffs to produce printed cloth has been very extensive, so that it has begun to be regarded as an independent way of printing.

Pigment printing is direct printing with paint, which is usually called dry printing, which is different from wet printing (or dyestuff printing).

< /p >

< p > by comparing the hardness difference between the printed part and the non printed part of the same fabric, pigment printing and dyestuff printing can be distinguished.

The printing area is slightly harder than the unprinted area, perhaps thicker.

If the fabric is dyed with dyestuff, there is no obvious difference in hardness between the printed part and the non printed part.

< /p >

< p > dark color printing is more likely to be lighter and less flexible than light or light colors.

When checking a piece of fabric with pigment printing, make sure that all colors are checked, because on the same fabric, dyes and coatings may be included.

White paint is also used for printing. This factor should not be ignored.

< /p >

< p > pigment printing is the most inexpensive printing method in printing production, because the printing of paints is relatively simple, and the process required is the least, usually without steam and water washing.

The paint has bright and rich colors and can be used in all < a target= "_blank" href= "//www.sjfzxm.com/" > textile > /a > fiber.

Their fastness and fastness to dry cleaning are good and even excellent, so they are widely used in decorative fabrics, curtain fabrics and < a target= "_blank" href= "//www.sjfzxm.com/" > dry clothes > /a > fabrics.

In addition, paints will not produce large chromatic aberrations on different batches of fabrics, and they will also have good coverage on the bottom.

< /p >

< p > with the continuous washing or dry cleaning, the pigment printing will fade gradually and the color will fade away.

This is due to the continuous rotation and stirring of the resin during the cleaning process.

After 20 to 30 times of cleaning, the printing cloth will obviously fade.

The color fastness is improved due to the use of resin and silicone softeners in the finishing process.

It should be noted that dark colors are more likely to fade than lighter or lighter colors.

< /p >

< p > coating makes a href= "//www.sjfzxm.com" > fabric > /a > the handle feels hard, light color is not very obvious, dark color is very prominent.

Paints are not particularly resistant to wear, especially dark ones.

Dark paint should be especially avoided in furniture such as upholstery fabrics.
