Technical Field

The invention relates to the technical field of chenille spinning, in particular to a lint-shedding-preventing chenille yarn and a production process thereof.

Background

The chenille spinning machine is spinning equipment for producing chenille yarns, the chenille yarns have fluffy and plump fluff, soft handfeel and bright colors, and are widely applied to household decorative fabrics, automobile decorative fabrics and garment fabrics at present.

The chenille yarn mainly comprises two core yarns and a plurality of tufts of wool yarns (decorative yarns), and the specific weaving mode is as described in journal articles: described in "Jiangsu textile" (11-st. populi aspiration 2005): the chenille spinning is carried out by using components such as a rotating head, a gauge piece 103, a cutter 104 and the like;

referring to fig. 1, one chenille head produces two chenille yarns at the same time, and each rotary head produces two chenille yarns at the same time, each chenille yarn being composed of two core yarns 1 and several tufts of pile yarns 4 (or finish yarns);

in the weaving process, two core yarns 1 are converged under the guidance of the first roller 105 and the second roller 106 respectively, and form subsequent twisting; the rotating head winds the pile yarn 4 around the periphery of the gauge piece 103 in a looping mode, the cutter 104 continuously cuts the looped pile yarn 4 into two half loops, and the formed short pile is clamped in the twist of the two core yarns 1 to form the chenille yarn.

The specific chenille textile machine can be seen in Chinese patent application No. 201410490824.1: a chenille spinning machine comprises an electronic machine head, a compression roller part, a rotary head part, a roller output part, a lifting yarn guide mechanism, a central balloon yarn guide, a spindle winding part, a winding spindle transmission system and a raw yarn creel device; the electronic machine head can realize clamping and mixing of core yarn and wool yarn by matching with the press roll part, the rotary head part and the roller output part so as to output semi-finished chenille yarn, and modules such as the spindle winding part, the winding spindle transmission system, the original yarn creel device and the like can realize twisting of the core yarn, so that the wool yarn can be clamped in the twist of two core yarns so as to output finished chenille yarn, and the finished chenille yarn is wound on the periphery of the winding bobbin.

In the twisting process, as shown in fig. 2, the semi-finished chenille yarn output from the electronic machine head passes through the yarn guide 6, then passes around the ring twisting hook 101 which is slidably fastened on the inner periphery of the ring 10, and finally is wound on the outer periphery of the winding spindle 102, and the rotation of the winding spindle 102 can drive the ring twisting hook 101 to rotate, so that the twisting operation of the mixed yarn can be realized.

However, the conventional chenille spinning machine has disadvantages in that when the chenille spinning machine performs chenille spinning by using the conventional spinning method: because the wool yarns 4 are clamped in the twist holes of the two core yarns 1 only by the clamping force (the two core yarns 1 can form a plurality of twist holes arranged along the length direction of the yarns after being twisted), the connection force of the wool yarns 4 and the core yarns 1 is weaker, and the wool yarns 4 are easy to fall out of the twist holes of the core yarns 1; moreover, when a large number of pile yarns 4 are dropped out of a certain twist hole (a plurality of pile yarns 4 can be inserted into each twist hole), and the twist cannot be tightly supported, the tensioning degree of the adjacent twist is affected, and the pile yarns 4 in the adjacent twist can be more easily pulled out, so that the avalanche effect is easily formed, and the pile yarns 4 on the whole chenille yarns are less dropped.
