Blank inspection and sewing of grey fabrics.

The grey inspection is mainly to control the quality of the Zigzag cotton grey fabric, to see if there are any abnormalities such as drawing, weft, dead fold, macular, mildew, etc. At the same time, it is necessary to check whether the fabric of Zigzag cotton is consistent with the requirements. When weaving, to keep the yarn from lint, the yarn is sizing, so it is necessary to desizing before dyeing to facilitate coloring. If the desizing is not clean, defects such as colored flowers and pulp spots will appear on the cloth surface after dyeing. After desizing, it is generally necessary to wash it with water, otherwise, the PH value of Zigzag cotton will be high, and abnormalities such as poor dyeing will occur.

Dry and check for quality.

Non-contact drying There are two types of non-contact dryers and setting machines. There is no contact between Zigzag cotton and the heater. The purpose of drying is achieved by spraying hot air on Zigzag cotton. Mainly used for drying overflow dyed products to keep Zigzag cotton fluffy and rich. The drum drying is the direct contact between the cloth and the drum, and the purpose of drying the cloth is achieved by heating the drum. Zigzag cotton, which is mainly used for jigging and beam dyeing, can also be dried on a tumble dryer first, and then go to the setting machine for water-repellent processing to improve the water-repellent degree. Then check the dyeing degree and fabric quality of Zigzag cotton.

Styling and calendering.

Zigzag cotton has stable physical and chemical properties after being shaped. At the same time, some functional processing can be done in the setting section. Because the setting temperature is high, you should pay attention to the color changes before and after setting, especially some sensitive colors. The setting can control the width, warp and weft density, shrinkage rate, etc. of the fabric, especially the shrinkage rate control, which directly affects the processing cost, so special attention should be paid to it. The function of calendering can soften the hand feeling, make the calendered surface of Zigzag cotton smoother, reduce the gap between the fibers of Zigzag cotton, prevent the velvet effect or achieve higher water pressure when gluing. The three elements of calendering are temperature, speed, and pressure. Calendering will change the color of Zigzag cotton. Gluing can make Zigzag cotton waterproof, velvet-proof, windproof, and other functions, and it can also fix Zigzag cotton, increase its appearance, and thicken its feel, which makes Zigzag cotton more useful. Then inspect the quality of the finished products, classify them into grades, and pack them for shipment. Generally, an inspection record and a different table should be made to ensure the quality of Zigzag cotton.
