Sylic Textile Auxiliary Information

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.

Surface treatment with silicone oil is to spray a solution or emulsion containing silicone oil (by spraying, coating, or dipping) at a low concentration onto a clean, dry surface. Read More

Light fastness refers to the degree of discoloration of colored fabrics by sunlight. The test method can be sun exposure or daylight machine exposure. The fading degree of the sample after exposure is compared with the standard color sample. It is divided into 8 levels, 8 is the best, and 1 is the worst. Fabrics with poor light fastness should not be exposed to the sun for a long time, and should be dried in the shade in a ventilated place. Read More

Composite fibers are two or more polymer melts, split by a special distribution plate, and extruded through the same spinneret hole. There are hundreds of types of composite fibers, and there are many classification methods. According to the production method, they can be divided into composite spinning and blended spinning. According to the spinning form, there are 5 commonly used types: co-spinning, side-by-side, skin-core, Splinter type, island type. Polyester/nylon composite fiber, which not only has the advantages of nylon's abrasion resistance, high strength, easy dyeing, and moisture absorption, but also has the advantages of good polyester elasticity, good shape retention, stiffness, and non-ironing.
