Matters Needing Attention In Processing Technology Of Burnt Out Printed Fabric

(1)

When entering the printing and drying room, it is required to be smooth and not wrinkle, otherwise it will cause carbonization unevenness, similar to dyeing coloured flower defects.

2. After carbonization, the fabric will be released in a timely manner, and the air will dissipate quickly, so as to prevent the residual acid from eroding and cause the strength to drop.

(3) during the storage process, the residual acid can easily absorb moisture in the air and extend each other, causing the outline of the flower pattern to be unclear and difficult to wash after carbonization, so it is not suitable to store.

4. The carbonization temperature and time are not enough.

Part of it is opaque white, and it is not easy to wash away, resulting in carbonization is not clean.

When the carbonization temperature is too high, the pulp is dark brown, and its residue is not easy to wash, which seriously affects the fabric strength.

During carbonization, the fibers decompose quickly in the process of rotten flowers and carbonized rapidly, so that carbonized materials are firmly attached to polyester or ground tissues, and a little water-soluble solubilizing agent can be added to help remove water.

It is difficult for the paste to adhere to each root with bubbles.

On the other hand, it will cause unevenness of rotten flowers. In order to prevent this problem, acid resistant defoamer must be added.

When printing the sour paste, choose the big round mouth scraper, scrape two knives, scrape the color paste to ensure its permeability.
