Basic Knowledge Of Fabric 5-- Dyeing Cloth And Rendering Cloth.

Zha dyed fabric is a folk dyed fabric with a long history in China.

Tie dye tie-dyeing is also called skein dyeing.

Before dyeing, according to the design requirements, tie the thread at different parts, then loosen the thread to get the natural color pattern.

Like the batik cloth, the tie dyeing cloth is only a blue and white variety.

Now it has developed into all kinds of colors, and the fabric has also developed from single cotton cloth to silk, synthetic fiber and all kinds of blended fabrics.

Tie dyeing tools also developed from pure tie lines to various special tools.

The present dyed cloth has been developed from the dress materials of rural women to fashion fabrics.

There are three steps to make tie dye: dyeing before treatment, strapping and dyeing, and dyeing after treatment.

Pretreatment before dyeing

In order to ensure uniform dyeing in tie dyeing process, fabric pretreatment is necessary.

Because fabrics often contain slurry, auxiliaries and natural impurities of certain components.

Before dyeing, there are:

Desizing: the purpose is to remove the slurry from the slurry by adding boiling agent, such as lye, oxidant or amylase.

Dosage: the agent is 3% of the cloth weight and the water is 30 times the weight of the cloth.

Refining: the purpose is to remove the natural impurities and residual slurry on the fiber, and use the caustic soda to boil.

Dosage: caustic soda is 3% of cloth weight and water is 30 times of cloth weight.

Bleaching: used to remove pigments and residual impurities, usually with sodium hypochlorite or hydrogen peroxide and boiling water.

Dosage: bleach is 3% of cloth weight and water is 30 times of cloth weight.

In addition, pretreatment of silk is done with soap solution plus sodium carbonate and water refining.

Ironing and ready to use: use electric iron to flatten the rinsed cloth for drawing pattern and binding.

Strapping and dyeing: mark the designed pattern with chalk on the cloth or draw it with drawing fluid, then bind or sew the cloth.

When finished, immerse in the water and soak it. Remove it for a little while, and put it in the prepared dye solution or dip or dye it for a certain time until it dries. Then rinse and dry it with clean water.

After dyeing treatment: the bundles can be untied when the air is dried and the iron is pressed and smoothed.

After finishing the tie dye finished products, some of our products also adopted some other skills to make the products more artistic.

These skills include hand embroidery, hand drawing, embroidery, pricking, and cross stitching.

Rendering cloth is a kind of fabric produced by porting a picture.

The production method can be gradually depicted on the cloth from deep to shallow, and can also be diluted with water from similar and adjacent dyes to be directly painted on the cloth, so that they can naturally be infiltrated and connected to form multi-level colors and patterns.

In addition, it can also use the spray paint to dye the cloth to achieve the multi-layered effect of color moistening, bright and soft.

It is also possible to spread the stain or agent on the fabric to form a deep or shallow effect.

The fabric produced by the rendering method has the color of "dream combination".

Discharge is also known as "water painting" in the folk. It is a printing method that uses blue sulphuric acid to throw out the color of indigo cloth and form blue and white patterns.

When making, first dyed a piece of fabric into dark blue with plant indigo blue, then dilute the sulphuric acid in a certain proportion, and paint it with a brush on the fabric with dilute sulfuric acid.

After painting, rinse the fabric into clean water, showing a white pattern on the blue bottom.

This method is convenient for painting and large in degree of freedom.
