Discussion On The Technology Of Net Printing And Rotting Flowers In Textile And Apparel Industry

In recent years, with the development of the market, sofa backrest, handrails, quilts, bedspreads, curtains, tablecloths and tea tables are commonly used in hotels, restaurants, hotels and conference rooms.

There is a great demand for such products.

These craftwork has many advantages, such as high strength, good abrasion resistance, good color fastness, no ironing, wrinkle resistance, good washing and quick drying.

Rotten flower craft is the use of two kinds of acid resistant different fiber blended textiles.

After acid printing and chemical processing, the acid resistant natural fibers are partially rotted away.

Expose the acid resistant chemical fiber part, form a crystal clear flower pattern, make it look gorgeous and gorgeous.

In addition to using special equipment, the main process is to use manual platen printing.

The quality requirements are manifested in the pparency of rotten flowers. The contour of the flower pattern is clear, impermeable, few flowers, many flowers, continuous lines, beautiful patterns and accurate layout.

When designing flower pattern, avoid excessive, too small dots, lines and surfaces.

For the design of the combination of rotten prints, the rotten flowers and

When the parts are connected, proper space should be kept to prevent the mutual penetration of burnt out paste and printing paste.

Destroy the effect of flower pattern.

Register should not be too much to avoid difficulties in the whole version.

The choice of burnt out grey cloth is mainly supplied by the following kinds of burnt out grey cloth, such as polyester / cotton core cloth, good pparency of rotten flowers and suitable for high-grade rotten flowers.

Polyester / cotton blended fabric has poor pparency in burnt out parts and can be used for general burnt out products.

Acrylic / cotton core cloth, good pparency of burnt out parts.

The dyeability of polyester is poor.

The choice of rotten silk screen.

Like polyester mesh, it has a longer service life.

In the absence of polyester mesh, you can also use nun Tun screen, choose 160~200 mesh as a good.

When designing the manuscript, we should pay attention to the following questions:

When drawing the manuscript, there should be an appropriate gap at the flower type wiring point, and the lines should be fine, symmetrical and accurate.

The film should be kept clean and the acid resistant photosensitive adhesive should be selected for rotten plate making.

The preparation of rotten pulp is sulfuric acid with a concentration of 98%.

The amount of sulphuric acid in each litre of burnt out pulp is about 20 ~ 60mL.

With potato starch, but not too thin, too thin can not reach the purpose of fixed rotten pulp in flower position.

Too thick slurry, poor penetration effect, difficult to scrape printing, affecting the integrity of the flower pattern.

It can also be used as white dextrin, which accounts for 12% to 20% of the pulp.

You can also use synthetic dragon glue, accounting for 2% to 4%.

After the printing is finished, steaming or baking can be used to carbonate the finished fabric. The carbonization process determines the carbonation time with the temperature of baking. When the drying begins, yellow spots on the gray cloth appear yellow, and as time goes on, the color gradually deepens to light brown and dark brown until dark brown.

It is hard to wash the residue of burnt out pulp when it appears dark brown.

In order to guarantee the quality and general temperature to grasp the light brown in the burnt out area, it is easy to wash away the residue of burnt out pulp.

It should be noted that the preparation of rotten flowers, the proportion of slurry and acid and the baking time have to undergo several tests until the most suitable time.

Rotten plates should be frequently washed in the process of scratching to prolong the service life.
