[Fabric knowledge] Velveteen fabric types
With the development of science and technology and the continuous improvement of consumer demand, not only the overall development of various organizational structures Cotton velveteen has emerged one after another, and various chemical fibers have continued to squeeze into the ranks of velveteen, making the varieties and specifications of velveteen endlessly varied.
Plain weave velvet series
Ordinary velveteen is made of bottom warp and pile warp arranged at intervals and weft threads one above and one below plain weave, woven double-width at the same time, and made of cut velvet. These warps and wefts can be made from a single yarn or from multiple strands, woven into yarn velveteen and thread velveteen. Various finenesses can be selected and woven into various specifications. Through this different arrangement and combination, a variety of cotton velveteen series products of different specifications can be produced. Changes in composition specifications lead to corresponding changes in fabric thickness, feel and gram weight per square meter. It also affects a series of processes such as dyeing, printing, and pre- and post-processing, and even the equipment required cannot be used universally.
Weft weight velveteen series
Velveteen with plain weave structure has many intersection points of warp and weft, so the fabric is stiff and feels hard. Replace the weft threads with two heavy weft threads and one single weft thread interwoven with the warp thread to obtain weft-weight velveteen. By selecting warp and weft of different fineness, weaving into different warp and weft densities and widths, we can also develop many different specifications of weft weight plain series velveteen. Because the weft-heavy velvet has fewer warp and weft interlacing points, it feels softer. The soft tissue structure makes it easy to produce wrinkles during dyeing and finishing. Therefore, for the dyeing and finishing of weft-weight velveteen, some corresponding measures must be taken to avoid wrinkles. In addition, due to the addition of weft in the weft-weight velvet structure, the number of pile warps on the suede surface is relatively reduced, making the pile sparse and easy to reveal the bottom. For this product, during post-finishing, it is necessary to strengthen brushing and other treatments to make the fluff fluffy and turn it to one side to cover up the phenomenon of bottom exposure and increase the smoothness and fullness of the suede surface.
Flash Velveteen
Using ordinary viscose and other regenerated fibers as the pile warp in the ordinary velveteen structure forms shiny velveteen. Because the surface of these regenerated fibers is smooth and smooth, they easily reflect light in the same direction and become bright and shiny. In addition, there are few crystalline areas in its internal microstructure, and its coloring rate is high. After printing and dyeing, it has a bright color and becomes a sparkling velveteen, which is popular for a while. However, because the surface of the regenerated fiber is smooth, the frictional resistance between the nodes where it interweaves with the weft threads is very small. During the consumption process, these fluffs are easy to fall off. Therefore, glitter velvet is generally only suitable for decorations such as curtains and curtains, and is rarely used for clothing.
Snowflake Velveteen
Both ordinary velveteen and weft-weight velveteen can be made into snowflake velveteen. The warp is made of polyester-cotton blended yarn, and the polyester component is not dyed during dyeing. In this way, the polyester fibers in the suede remain white and are evenly and softly blended in. The dyed color shows a snowflake-like effect, with a quiet and simple natural beauty. Suits and windbreakers sewn with this kind of fabric look dignified and unique. The dyeing and finishing of snowflake velveteen can be carried out according to the process of ordinary pure cotton velveteen.

If the velvet warp is made of pure cotton and regenerated fibers and arranged at regular intervals, and each section is of an appropriate width, then the velveteen fabric with different specifications will be woven. Due to the difference in coloring rate between cotton and regenerated fiber, although the same dyeing process as ordinary pure cotton velveteen is used, two completely identical hue effects can be obtained, exactly like using two different fabrics and sewing them together. The clothing also has an elegant style.
