The printed fabric supplier explains the process flow of dyed cloth

The colored flowers of dyed cloth are caused by many reasons, such as too fast temperature rise in the cylinder and too fast or too slow rotation speed of the cylinder pump.

Printed fabric supplier said that it also requires some experience to see the colored flowers. If a novice is told by others, it is basically difficult to find them.

And personal sensitivity to color. This is particularly important. The dyed fabric is mainly mixed dyeing and reactive dyeing. In particular, blending is more likely to have color flower than activity.

In particular, some colors are dark and dark (such as dark gray, purplish red, coffee, etc.).

Printed fabric supplier said that the process of fabric dyeing, dyed fabrics and processed fabrics (fabrics, knitting, etc.) are dyed fabrics through professional dyeing equipment, and the finished fabrics produced by the processes of packaging, sewing, sea pulp oxygen bleaching, mercerization, setting, dyeing, finishing and Jesus axis are dyed fabrics.

Natural fibers contain impurities. In the process of textile processing, various slurries, emulsifiers and contaminated dirt are added.

The existence of these impurities will not only hinder the smooth dyeing process, but also affect the wearability of the fabric.

Printed fabric supplier said that the purpose of bleaching is to use chemical and physical mechanical action to remove impurities in the fabric, make the fabric white and soft, have excellent permeability, and provide qualified semi-finished products for dyeing, printing and finishing.

Printed fabric supplier introduces the technological process of dyed cloth

Prepare the original cloth

The preparation of raw cloth includes inspection, overturning (placement, box, printing) of raw cloth and joints.

The purpose of raw cloth inspection is to check the quality of rough cloth and solve problems in time. The inspection contents include physical indexes and appearance defects.

Singeing

Printed fabric supplier said that the purpose of singeing is to burn the cotton wool of the cloth to make the cloth smooth and prevent dyeing imbalance and printing defects due to the existence of cotton wool during dyeing and printing.

Desizing

In order to weave smoothly, textile mills often sizing warp yarn to improve strength and wear resistance.

The slurry on the blank will affect the absorption performance of the fabric, affect the quality of dyeing products and increase the consumption of hair dye, so the slurry should be removed before cooking. This process is called desizing.

Dyeing

Dyeing is a complex process, and the dyeing processes of different quality fabrics are different. Cotton, polyester, chemical fiber products and blended products are different.

Some use pressed salt and scrolls, some use high temperature and high pressure dyeing, some only need to be dyed once, and some need to be colored many times.

Dyeing can pass through the mill, but it is also a difficult process. Because the color control of dyeing is not only known, but also many unknown things such as dye stability, steam control, rolling pressure control and so on at different temperatures.

The long car for dyeing is divided into two parts: front car dyeing and rear car fixation. The dyeing method depends on the type of dye used first.

Dyes generally include reactive, serine, vulcanization and paint, which have their own advantages and disadvantages. They generally depend on the required color and cannot be exchanged.

Finishing

Finishing is a textile technology engineering that endows garment fabrics with wearability and beauty.
