What kind of fabric is cotton velveteen? What is cotton velveteen suitable for? Warp or weft yarns are used to form a towering dense pile cotton fabric on the surface of the fabric. The fabric body is thick, soft to the touch, and the pile is short, dense, even, and not easy to fall down. The suede surface has soft luster, wrinkle resistance and warmth retention. After dyeing or printing, it has a gorgeous appearance. It is suitable for women’s spring, autumn and winter clothing, shoe and hat fabrics, sofa covers, curtains and other decorative items.
According to the raising processing method, it is divided into two types: weft-cut velveteen and warp-cut velveteen. Cut velveteen is the traditional production method of cotton velveteen. Fabric structure of cut weft velveteen. A set of warp yarns and two sets of weft yarns are interwoven with a unique fabric structure to form a pile fabric. The warp-cutting machine cuts the pile and weft floating yarn segments on the surface of the pile fabric in the middle, and then undergoes repeated brushing processing to make the cut yarns The first twist is reduced to form upright and fluffy fiber piles, thereby forming a pile plane, which is then scoured, singed, brushed repeatedly, dyed or printed, and finally stretched, glazed, and shaped to form a product.
The gray fabric of warp-cut velveteen is a double-layer woven on a loom with double-layer weaving technology For velvet gray fabric, the side splitting machine cuts the velvet warp connecting the two layers of ground fabric, and separates the double-layer gray fabric into two single-layer velvet gray fabrics. After scouring, it is de-padded, de-twisted, brushed, singed, dyed or printed. Then the product is stretched, glazed and shaped. Cut warp velveteen uses two sets of warp yarns (one set is the ground warp yarn of the ground cloth. The other set is the pile warp yarn) and a set of weft yarns are interwoven. The ground warp and pile warp have the most different let-offs, so two warp beams are needed. And two warp let-off mechanisms can be used for weaving. The thickness of double-layer velvet fabric is related to the pile height, the greater the pile height. The thickness of the double-layer velvet gray fabric is also larger, which makes the stretcher (edge supporter) and rolling mechanism used for general fabrics inapplicable.
Because it is a double-layer fabric, the opening heights of the ground warp and pile warp are also different. Requirements, the open pedals of ordinary fabrics are not suitable. The above are all contents that require technical transformation of general looms and cannot be ignored.
Double layer of warp-cut velveteen There are also two ways of weaving:
One is “double-layer single shuttle” The “knot” weaving method uses the original shuttle picking mechanism of the loom to shuttle the upper and lower layers of fabric in an orderly manner. During each revolution of the loom, the warp yarn has only one shed for the shuttle to pass through, and the warp yarn has only one shed for the shuttle to pass through. Weft, therefore. The production efficiency of double-layer velvet gray fabric is low;
The second is “double-layer double shed weaving” Method. During each rotation of the loom, the upper and lower layers of the double-layer fabric are opened into sheds at the same time, and the weft yarn is fed by a rapier feeder or air jet airflow. The double-layer fabric is woven with warp and weft at the same time, producing The efficiency has been doubled. Cotton velveteen is a high-end clothing material for women and children. Therefore, fine, high-quality and commercial cotton yarn should be used for weaving.
General warp yarns (including pile warp) use tip comb J14.577tex
040 British branch) or J9.718tex x 2
(J60/2 English branch) strands are used as raw materials. The weft yarn is made of single yarn corresponding to the warp yarn fineness. The cotton velveteen used for shoes is generally 18.22125tex x
2 (32/2 English) or 13.88286tex x
2 (42 inch count/2) strands are warp yarns, and 18.22125tex (32 inch count) or 14.577tex (40 inch count) single yarn is used as weft yarn. The organizational structure generally adopts plain weave. The longitude and latitudinal degrees are the same, at 55%
– between 65%. Cotton velveteen can also develop new varieties of yarn-dyed strips and plaids.
