Processing Technology And Characteristic Analysis Of Burnt Out Fabric

< p > rotten fabric is made of polyester core and coated or blended with cotton, acetic acid, viscose and hemp fibers.

Then, according to their different properties of acid stability, the sour pulp is corroded and carbonized on the above fabrics, and its acid resistant fibers (i.e. cotton, acetic acid, viscose, hemp and other fibers) retain their acid resistant fiber polyester, so that they become plucent patterns. This process is known as burnt out flowers.

In the printing of sour paste, it can also be printed with white paint as the edge of the rotten flower part, or add acid resistant disperse dyes in the sour paste, so that the polyester part of the pattern part is coloured, or the first printing pigment is used as the anti printing paste, then the overprint of the sour paste, the printing effect is produced in the printing part, or the fabric is dyed before the rotten flower, then rotten flowers, etc., so that the shape of the flower is rich and colorful.

< p > burnt out printing was originally used for silk and its interwoven fabrics, such as burnt out silk, Qiao Rong and burnt out velvet, then used for burnt out polyester / cotton fabrics and other fabrics.

The rotten fabric is interwoven with two different fibers or mixed with a target= "_blank" href= "http://www.91se91.com/" > strong > textile < /strong > /a > one of the fibers can be destroyed by a certain chemical agent while the other fiber is not affected, thus forming a special style of burnt out printed cloth.

Usually acid resistant fibers such as silk, nylon, polyester and other fibers, such as viscose fiber and cotton, are woven or woven into fabrics, and then printed with strong acid. After drying, cellulose is hydrolyzed and carbonized by strong acid. After washing, they get plucent and concave and convex patterns.

With the popularity of the regression, rotten design is often used in a large number of decorative fabrics such as curtains, bedspreads, tablecloths and < a target= "_blank" href= "http://www.91se91.com/" > strong > dress < /strong > /a > fabrics.

< p > in addition to silk and silk, polyester cotton core spun yarn is widely used.

Printing on textiles with strong acid paste.

Sulfuric acid is the best for strong acids. Acidic salts such as aluminum sulfate and sodium bisulfate can also be used, but the effect is not as good as sulfuric acid.

The printing paste should be able to withstand strong acids and has good penetrability, clear print and easy washing.

This kind of paste contains white dextrin, synthetic dragon glue, oil / water emulsion paste and so on.

After printing, it is dried, dried at more than 100 degrees, washed in rope, and removed carbonized.

If the drying temperature is too high, the printing area is dark brown and hard to clean. When the temperature is not enough, the printing area is white and opaque, indicating that it is not effective enough to wash and remove.

Check whether the baking temperature is suitable, the fabric can be moved by hand under tension condition, so that the residue can be separated immediately.

< p > rotten printing can be done by direct printing or anti staining printing.

The latter is pre printed with paste. After drying, it is pickled with acid and steamed to remove the ground color part, which achieves special effects.

The quality requirements of rotten flowers are manifested in the pparency of rotten flowers. The contour of the flower pattern is clear, impermeable, not flowered, many flowers, continuous lines, beautiful flowers and accurate plates.

In the process of rotten flowers, the pattern effect can be more eye-catching if the nested printing or color printing is applied to the remaining fabric areas.

When designing the flower pattern, avoid excessive, too small points, lines and surfaces, so as to prevent the flowers from losing flowers and the disadvantages of flower contour lines.

For the design of the combination of burnt out and printing, when the connection between burnt out and printing parts should be done, proper gaps should be kept to prevent the mutual infiltration of burnt out paste and printing paste when damaging printing, and destroy the effect of flower pattern.

It is not appropriate to register too much.

Generally speaking, plain fabric is used in the tissue design of < p > rotten fabric. The following four problems should be paid attention to in fabric weave design: the choice of fabric tightness.

The density of burnt out fabric includes two concepts. One is the tightness of fabric core spun yarn, the other is the tightness of fabric screen part. Two.

When the fabric is tight enough, weaving is difficult to make. If the fabric is tight enough, the screen part will easily cause the displacement of the warp and weft.

The choice of burnt out grey cloth is that the supply of rotten bloom in the market is less than a target= "_blank" href= "http://www.91se91.com/" > strong > cloth > /strong > /a > mainly in the following kinds: polyester or cotton core white cloth, the rotten flower part has good diaphaneity and is suitable for high-grade rotten flower products.

Polyester or cotton blended fabric has poor pparency in burnt out parts, and is suitable for general burnt out products.

< p > < a target= "_blank" href= "http://www.91se91.com/" > strong > designer < /strong > /a > when designing the manuscript, we should pay attention to the following questions: when the script is scribed, the appropriate gap should be left at the flower type wiring point, and the lines should be fine, symmetrical and accurate.

The choice of reed number for weaving is aimed at the uniform arrangement of weft knitted fabric and weft yarn. Generally, reed with higher reed number is more suitable for improving the quality of products.

In actual production, it is better to wear a warp per reed when wearing reeds, and two warp yarns are at most for each reed.

In addition, the choice of twist coefficient of core spun yarn is closely related to the twist factor of core spun yarn and the quality of rotten fabric.
