Description
Technical Field
The invention belongs to the technical field of chenille yarn production, and particularly relates to a low-twist non-delinting chenille yarn and production equipment and a production process thereof.
Background
The chenille yarn is also named as corduroy, and is one kind of fancy yarn produced with two plied yarns as core yarn and through twisting and spinning with down yarn sandwiched between two plied yarns. The chinese utility model patent with application number CN201720964971.7 discloses a chenille machine for producing conventional chenille yarns, which comprises a frame, wherein the frame is provided with a plurality of core thread frames and a plurality of wool yarn frames, and the frame is movably provided with a ring spindle seat moving up and down and a power device driving the ring spindle seat; the frame is provided with a plurality of yarn forming units, each yarn forming unit comprises a velvet cutting device arranged on the frame from top to bottom, two ring spindles arranged on a ring spindle seat, a ring spindle motor driving the two ring spindles to rotate, and a core wire motor used for conveying two core wire roller assemblies of a core wire and driving the core wire roller assemblies.
When the chenille yarns are produced, the wool cutting device cuts the wool yarns into short wool yarns with specified length, the wool yarns are arranged in order and are twisted into semi-finished yarns by two core wires, and the semi-finished yarns are directly twisted into finished chenille yarns by a ring spindle. The resulting chenille yarn becomes very flexible since the cut end faces of the pile yarn are all at the ends of the core yarn.
However, if the twist is set to be high, not only the yield of the chenille yarn is reduced but also the chenille yarn becomes stiff. Because of the characteristics of the chenille yarn, the range of the chenille yarn used at present is basically limited to the range of home decorations such as sofa cloth and curtain cloth; because these fabrics are woven products, the yarn twist is slightly higher and not inferior to bias; if chenille yarns are used for knitted products, splaying is caused as soon as the twist is high, and sheds are caused as soon as the twist is reduced.
At present, the chenille yarn with soft (low twist) and non-delinting performance does not exist, and the twist of the conventional chenille yarn is basically about 700-1000T/M according to the counts of core wires and finished products; in addition, when the conventional chenille yarn is twisted, the ring seat continuously reciprocates up and down, when the ring seat is at a low position, the twist is higher, and when the ring seat is at a high position, the twist is lower, so that the twist of the chenille yarn is not uniform, and the deviation of about 30T/M can occur between the upper twist and the lower twist.
