Elastic velveteen series: The weft in the plain cotton velveteen or the weft weight velveteen is made of spandex core-spun yarn to obtain elastic velveteen. Elastic velveteen has good weft elasticity. Because spandex occupies a very small proportion (about 3%) in various specifications of elastic velvet, it is woven in the form of core-spun yarn. Therefore, the dyeing process is the same as ordinary velveteen, but it should be noted that chlorine bleaching is not suitable for bleaching; because of the large shrinkage rate and unstable width, pre-shrinking is required before scouring and bleaching.

Two-color velveteen: pure cotton for velvet warp and bottom warp, polyester yarn for weft, using the completely different dyeing properties of polyester fiber and cotton fiber, can process two-color velveteen. Polyester fiber can only be dyed with disperse dyes at high temperature. Cotton fibers are not dyed. Cotton fiber can still be dyed with the original dyeing process, and there is no effect on the color of polyester at this time. Therefore, the hot-melt method can be used to dye the polyester in the two-color velveteen first, and then dye the cotton, to obtain the two-color effect of different colors of suede and velvet back. The production process of this variety of velvet is more complicated, but it is popular with consumers and the sales market is widespread Optimistic.

Functional velveteen series: such as flame-retardant velvet, anti-ultraviolet velvet, antibacterial and deodorant velvet, water and oil repellent anti-fouling velvet, fragrance velvet, medical velvet, etc. The production of these velveteen products depends on the development and innovation of various corresponding auxiliaries at present, and the dyed velveteen semi-products are processed and finished by various processing and finishing using corresponding processes. These special functions are often not permanent, and while gaining characteristics, other original properties are often lost, such as darkening of color, rough hand feeling, lack of elasticity and so on.

Velveteen has the characteristics: the surface is covered with a layer of fluff, so the fabric has a rich texture, soft and elegant luster, strong color, soft hand, elasticity, and good anti-wrinkle performance; the fluff on the fabric surface forms an air layer, and the fabric has good warmth retention performance; when used due to fluff The section friction with the outside, so the fabric has good wear resistance.

Printed velveteen series: various specifications of ordinary velveteen, weft-weight velveteen, elastic velveteen, etc. can be printed with various patterns through general textile printing methods to produce various types of printed velvet. The printing process and operation must adapt to the characteristics of velveteen, so as to achieve good penetration and no exposure. For velvet printing, direct printing is often used. The direct printing process is simple and easy to operate. The printing paste is directly printed on the velvet. After steaming and fixing, the dye is fixed on the velvet to obtain a three-dimensional pattern. However, because the velveteen hair is dense and has a certain height, the patterns printed by the direct printing process are not ideally connected. Printed velvet with high quality requirements is usually printed by hanging printing method. The vast majority of velveteen printing is used to cover printing after dyeing light colors or hanging printing after dyeing dark colors. The printed patterns are clear and lifelike with ideal results.

Printing is often manual scratch printing, and the number of scratches is determined according to the temperature of the platen and the viscosity of the printing paste. Generally, the temperature of the platen is 40℃～42℃, and the room temperature is about 30℃. Scrape back and forth 4 to 6 times with a big round rubber spatula. The color paste can basically penetrate into the root of the pile, and excessive scratching is easy to scratch.
