High temperature dyeing machine dyeing and finishing process

1. Preprocessing

All natural fibers contain impurities and various sizing agents, oils and contaminants are added during fiber processing. The existence of these impurities not only hinders the smooth progress of dyeing and finishing, but also affects the abrasion resistance of the fabric.

Therefore, it uses chemical and physical mechanical action to remove impurities in the fabric. The fabric is white and soft, has excellent penetration performance, and presents the natural luster of the fabric that meets the wearing requirements. It is a qualified semi-finished product.

2. Dyeing

Textiles are treated with dye baths (dyes + auxiliaries + solvents). The chemical or physicochemical combination of dyes and fibers transfers the dyes in the dyebath to the fibers, producing insoluble colorants. The fabric is uniform in color and has excellent discoloration resistance.

According to the contact method between the dye and the cloth (dyeing process), it can be divided into two types: dip dyeing and pad dyeing.

3. Printing

Printing belongs to local dyeing and requires certain resistance to discoloration. It is necessary to combine dyes into color paste (dye + color paste + chemicals), and dye the fabric according to the preset pattern to form a pattern with certain discoloration resistance.

Printing is divided into flat screen printing, rotary screen printing, transfer printing, digital printing, etc.

4. Organize

Also known as textile finishing or finishing. Through physical, chemical or a combination of the two methods, improve the appearance, feel and internal quality of the fabric (hard finishing, soft finishing, calendering or ridged, etc.) and the abrasion resistance of the fabric, and give the fabric some special practical effects.
