Sylic Textile Auxiliary Information

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.

Be sure to pay attention to the aurora print in the production process of the sanded fabric, because once there is aurora print, white spots will be formed during dyeing. Therefore, the rolling car and the cloth guide rod should not be stuck with hard objects during the mercerizing alkali washing after the sanding. It is necessary to make frequent inspections. When dyeing, it is found that there are white spots of aurora printing and should be treated before dyeing. Read More

Silicone in cosmetics refers to all kinds of polysiloxane polymer compounds (Silicone). Silicon is found in the vast majority of cosmetics, as well as in many skin care serums and oil-free creams, especially from big-name department store brands. Read More

The stability and low activity of silicone oils enable them to be used for steam autoclaves, dry heat autoclaves, ethylene oxide autoclaves, and low dose radioclaves. Read More

The cloth dyed by the long cotton car must be dried in a drying cylinder, and then packed in a large package or stacked in a cloth box. If it is not sufficiently cooled, especially the cloth in a large package, the surface temperature of the fabric may be higher when it is soft. This causes the temperature of the working fluid in the rolling groove to rise (especially in summer), sometimes reaching above 60°C, and when the heat resistance of ordinary silicone oil is not good, it can also cause sticking of the roll. It is better that the temperature in the rolling groove does not exceed 40 ℃. Read More

Polyester fiber is a hydrophobic synthetic fiber. The molecular structure of polyester lacks active groups that can combine with dyes. Polyester molecules are arranged relatively tightly, and there are only small voids in the fiber. When the temperature is low, the molecules move thermally. The range of changing its position is small, and it is difficult for the dye molecules to penetrate into the fiber. Therefore, increasing the degree of plasticization of the fiber will help the dyeing process. In addition, the solubility of disperse dyes in water is very low, and the dyes in the dyeing solution must be dispersed in the dyeing bath in suspension by a large amount of dispersant. When dyeing polyester fiber, in order to achieve better dyeing effect, it is usually necessary to add a certain amount of dyeing auxiliaries. Read More

107 rubber is 107 type of room temperature vulcanized methyl silicone rubber for short, room temperature vulcanized methyl silicone rubber (RTV) is a new type of silicone elastomer came out in the 1960s, the most significant characteristic of this rubber is at room temperature without heating, pressure can be cured on the spot, the use is very convenient.
