6. For some mechanical tensions, manual tension control is required. Strict process operations, strengthen process operations, strengthen mechanical cleaning, reduce operating tension, and effectively reduce the shrinkage of flame-retardant fabrics.
7. The shrinkage rate of flame-retardant fabrics strengthens the inspection of mercerization processing machinery. Conditional dyeing factories can use straight rollers and cloth clips combined with mercerization production.
8. Varieties of flame-retardant fabrics with larger warp shrinkage must be pre-shrunk to reduce the shrinkage. In these tight machining. Just by mechanically relaxing the tension, the best shrinkage rate is as high as about 4%. This shrinkage rate should be further reduced by pre-shrinking. After the product is pre-shrunk, not only the shrinkage rate is reduced. At the same time, you can also get a better fabric feel, with clear and soft fabric texture.
9. For larger varieties of flame-retardant fabrics such as weft shrinkage, some of them have a large weft shrinkage due to unreasonable width of gray fabrics. Despite reasonable processing conditions, there is still a large weft shrinkage and poor processing conditions must be met. Further control measures must be taken to ensure that the mercerized varieties meet strict requirements for the falling cloth width. In addition, it is necessary to improve the specifications of the gray fabric and widen the width of the gray fabric without increasing the cost or increasing the cost to ensure that the weft shrinkage is reduced to the strict requirements.
10. For CVC flame-retardant fabrics, the qualitative mercerization process and operation must be carried out to better control the shrinkage rate.
