Insufficient shrinkage. The pre-shrinking effect is not good and the dimensional stability is poor. This is caused by the position of the pressure roller being too high, the temperature of the pressure roller being too low, the pressure on the cloth roller is not enough, and the tension of the cloth in and out is too high. The position of the pressure-bearing roller can be appropriately lowered, the spray wet can be controlled, the vapor pressure of the pressure-bearing roller can be increased, the pressure of the cloth roller can be increased, and the tension of cloth in and out can be reduced.

Anisotropic expansion of the fiber when it is soaked, that is, the length and diameter of the fiber increase, but the increase in diameter is much greater than the increase in length. For example, the diameter of cotton fiber increases by 14% after being soaked, but the length only increases by 1.1%~1.2%. Therefore, after the fabric is soaked, the fiber in the fabric becomes thicker due to expansion, but the length does not increase much, and the yarn must follow The thickening of the fiber increases the diameter.

Improper control of dyeing heating speed Some dyes have poor dispersibility and improper dyeing temperature control. Too fast will cause dye spots; dispersant or penetrating agent is not resistant to high temperature and cause secondary separation of dyes to form dye spots; some additives need to be added separately (high solid content) when adding additives (high solid content), not operating as required Suspended dots are combined with dyes to form dye dots; some color dots are very small and present a dot-like distribution and can only be found by careful observation, and are different from the color light of dyeing cloth. That's because the dye itself contains insoluble substances, and the dispersion of these dyes is destroyed during the manufacturing process and cannot enter the fiber. This situation mostly occurs in light-colored or brilliant-colored systems; the diffusion effect of red dyes may not be good, and a diffusing agent needs to be added to solve it. Read More
