Width continuous scouring scouring can be used for all kinds of silk fabrics, practicing white finished uniform than hung training finished unglued, there is no gray injuries, hanging loop, Buy Decorative Flags India and other flaws. Aircraft a higher degree of automation, save manpower, reduce labor intensity. The bath ratio is too large, water consumption, electricity consumption, steam consumption, higher refining costs. Improper operation, the thin fabric is easy to float, will be folded into a ring or off-center to produce wrinkle
(3) star-shaped frame scouring
Star frame scouring barrel hanging by the star silk frame and round training barrel composed of two parts. Concise, need artificial Pichou monolayer hanging on the hook can rotate star, and then scouring with a crane hanging round training barrel. Star frame scouring scouring agent, soap, soda ash, sodium silicate, sodium hydrosulfite, surface active agent, dosage and scouring trough hanging practicing the same.

Five other fabric pre-treatment Beach Warning Flags
(A) in the long chemical fiber fabric pre-treatment
The long chemical fiber fabric viscose blended fabric, there are long-fiber polyester acrylic blended fabrics and long fiber polyester nitrile rayon blend fabric. Long in the chemical fiber are of wool-like fabric, thick fabric requirements feel full, fluffy, elastic, thick hair style. The pros and cons of these styles, the key is the quality of dyeing and finishing.
Medium-and long synthetic fabrics do not contain natural impurities, Buy Feather Flags scouring and bleaching process is relatively simple, just singeing, desizing, and heat setting can be. In the long chemical fiber fabric pre-treatment must be taken to the loose process, in order to improve the wool-like effect.
A. The singeing adopt a small crater, strong flame, the faster the speed of the singeing process. Arrange the order of the singeing process can be based on factory conditions and species requirements, Promotional Feather Flags Buy Decorative Flags varieties of high temperature and high pressure dyeing, singeing should after transfection, so as not to affect the staining uniformity.
Two. The desizing desizing in loose, damp heat processing, the fabric can be the Desizing while full contraction, plump fluffy wool-like style. Long synthetic fabric on the slurry with PVA slurry, can be alkaline desizing or oxidant desizing. Alkaline desizing the fabric feel slightly stiff, slightly darker dye staining under the same hot melt conditions. Can also use the detergent desizing, the fabric soft to the touch after the desizing good elasticity, easy tenter. Desizing washed in washing machine on the loose after washing, then drying in the loose dryer. Buy Decorative Flags
3. The setting temperature of the heat setting to 190 ° C is appropriate. Before transfection setting can ensure dimensional stability in the dyeing process, reduce wrinkles, improve the staining quality.
(B), knitted pre-treatment
The knitted fabric has a soft touch, good air permeability, and rich scalability, comfortable to wear. Made of T-shirts, cotton sweaters, sweatshirts, gloves, socks. Knitted coils, loose structure, the external force easily deformed, and can not be subjected to greater tension, so the processing must be made fabric to maintain a relaxed state, and low-tension processing equipment, processing should be as short as possible.

A. Pretreatment of cotton knits
The main products of cotton knitted single jersey, interlock fabric. Knitting yarn before weaving, sizing, the fabric does not contain pulp. The first process is generally not singeing, do not need to desizing, usually only for scouring, bleaching and softening. Some species, such as single jersey, alkali reduction, in order to increase the density and elasticity of the fabric. Cotton knitted fabric treatment process has the following forms:
