Elastic velveteen series: The weft or weft weight velveteen in ordinary cotton velveteen is made of spandex core yarn to obtain elastic velveteen. Elastic velveteen has good weft elasticity. Because spandex makes up only a small percentage (about 3%) of elastic velvet of all sizes, it is woven in the form of core-spun yarn. Therefore, the dyeing process is the same as that of ordinary velvets, but it should be noted that chlorine bleaching is not suitable for bleaching. Due to the large shrinkage rate and unstable width, pre-shrinkage is required before boiling and bleaching.

Two-color velvet: Pure cotton is used for velvet warp and bottom warp, polyester yarn is used for weft, using polyester fiber and cotton fiber completely different dyeing properties, can process two-color velvet. Polyester fibers can only be dyed with disperse dyes at high temperatures. Cotton fibers are not dyed. The cotton fiber can still be dyed according to the original dyeing method, and there is no effect on the color of the polyester. Therefore, polyester can be dyed in two-color velvety by hot melt method, and then cotton can be dyed to obtain the two-color effect of suede and velvet of different colors. The production process of this kind of velvet is more complicated, but it is welcomed by consumers and the sales market is generally optimistic.

Functional velvet series: such as flame retardant velvet, anti-ultraviolet velvet, antibacterial and deodorant velvet, water and oil repellent velvet, essence velvet, medical velvet and so on. The production of these velvet products depends on the development and innovation of various corresponding auxiliaries, and then the dyed velvet semi-finished products are processed and finished through the corresponding process. These special features are usually not permanent, and while features are acquired, other original properties are often lost, such as darker color, rough feel, lack of elasticity, etc.

Velvety has the following characteristics: the surface is covered with a layer of fluff, which makes the fabric rich in texture, soft and elegant luster, rich color, soft feel, elastic, and good wrinkle resistance; The fluff on the surface of the fabric forms an air layer, and the fabric has good thermal insulation properties. Due to the friction between the fluff part and the outside world, the fabric has good wear resistance.

Printing velvety series: various specifications of ordinary velvety, weft velvety, elastic velvety, etc., can be printed into a variety of patterns through the general textile printing method, so as to produce various types of printed velvet. The printing process and operation must be adapted to the characteristics of velvety to achieve good permeability and no exposure. For velvet printing, direct printing is usually used. The direct printing process is simple and easy to operate. The printing paste is printed directly on the velvet. After steaming and fixing the color, the dye is fixed to the velvet to obtain a three-dimensional pattern. However, because the flat pile is dense and has a certain height, it is not ideal to connect the pattern printed by the direct printing method. Velvet with higher quality requirements is usually printed by hanging printing. The vast majority of velvets are used for overlay printing after light dyeing, or for hanging printing after dark dyeing. The printed pattern is clear and vivid, and the effect is ideal.

Printing is usually manually scratched, and the number of scratches depends on the temperature of the press plate and the viscosity of the printing paste. Usually, the pressure plate temperature is 40 ° C ~ 42 ° C, and the room temperature is about 30 ° C. Use a large round rubber spatula to scrape back and forth 4 to 6 times. The color paste can basically penetrate into the root of the pile, and it is easy to scratch by excessive scratching.
