Description
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.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The first embodiment is as follows: referring to fig. 3, the lint-shedding-preventing chenille yarn disclosed by the invention comprises two core yarns 1 which are parallel to each other, two hollow hot-melt adhesive yarns 2 and wrapping yarns 3 which are spirally wrapped outside all the core yarns 1, wherein a gap between the core yarns 1 is a material clamping gap, the wrapping yarns 3 divide the material clamping gap into a plurality of twisting holes which are distributed along the length direction of the core yarns 1, and a cluster of velvet yarns 4 is inserted into each twisting hole; each hot melt adhesive yarn 2 is fixedly wrapped on the periphery of one core yarn 1, and the wrapping yarn 3 can be made of any one of elastic polyester, elastic spandex and elastic acrylic.
The implementation principle of the embodiment is as follows: because the hot melt adhesive yarn 2 is added into the whole chenille yarn, the molten hot melt adhesive can bond the core yarn 1 and the wool yarn 4 in the later period of spinning (often needing to pass through a high-temperature environment), thereby greatly reducing the falling probability of the wool yarn 4;
in the semi-finished product stage of the chenille yarn (only consisting of two core yarns 1 and the wool yarn 4 clamped between the two core yarns 1), the chenille yarn 3 wraps and tightens the chenille yarn to enhance the resisting force of the core yarns 1 and the wool yarn 4 and reduce the falling probability of the wool yarn 4 caused by weaker clamping force of the core yarns 1; and a plurality of twist holes can be formed, the wool yarn 4 can be inserted into each twist hole, and after the processing is finished, the twist holes can reduce the probability of the deviation of the wool yarn 4 along the length direction of the core yarn 1, thereby improving the position stability of the wool yarn 4.
It should be noted that, when the hot-melt adhesive yarn 2 on the outer layer of the core yarn 1 is melted to be in a liquid state, the outer diameter of the core yarn 1 is reduced, and the wrapping yarn 3 becomes loose with respect to the wrapping of the core yarn 1, but since the wrapping yarn 3 has elasticity, the wrapping yarn 3 can be automatically contracted by the elasticity of itself after the hot-melt adhesive yarn 2 is melted to be in a liquid state, so as to prevent the falling-off of the pile yarn 4 due to the loosening of the wrapping yarn 3.
Example two: referring to fig. 4, the lint-shedding-preventing chenille yarn disclosed by the invention comprises two core yarns 1 which are parallel to each other, two solid hot melt adhesive yarns 2 and wrapping yarns 3 which are spirally wrapped outside all the core yarns 1, wherein a gap between the core yarns 1 is a material clamping gap, the wrapping yarns 3 divide the material clamping gap into a plurality of twisting holes which are distributed along the length direction of the core yarns 1, and the velvet yarns 4 are inserted into the twisting holes; the hot melt adhesive yarns 2 are parallel to the core yarns 1 and are wrapped in the wrapping yarns 3, each hot melt adhesive yarn 2 corresponds to one core yarn 1, and the hot melt adhesive yarns 2 can be fed into a chenille machine head in parallel along with the corresponding core yarn 1 in the spinning process; the fasciated yarn 3 is made of any one of elastic terylene material, elastic spandex material and elastic acrylic material.
The implementation principle of the embodiment is as follows: because the hot melt adhesive yarn 2 is added into the whole chenille yarn, the molten hot melt adhesive can bond the core yarn 1 and the wool yarn 4 in the later period of spinning (often needing to pass through a high-temperature environment), thereby greatly reducing the falling probability of the wool yarn 4;
in the semi-finished product stage of the chenille yarn (only consisting of two core yarns 1 and the wool yarn 4 clamped between the two core yarns 1), the chenille yarn 3 wraps and tightens the chenille yarn to enhance the resisting force of the core yarns 1 and the wool yarn 4 and reduce the falling probability of the wool yarn 4 caused by weaker clamping force of the core yarns 1; and a plurality of twist holes can be formed, the wool yarn 4 can be inserted into each twist hole, and after the processing is finished, the twist holes can reduce the probability of the deviation of the wool yarn 4 along the length direction of the core yarn 1, thereby improving the position stability of the wool yarn 4.
It should be noted that, when the hot melt adhesive yarn 2 on the outer layer of the core yarn 1 is melted to be liquid, the outer diameter of the core yarn 1 is reduced, and the wrapping yarn 3 becomes loose relative to the wrapping of the core yarn 1, but because the wrapping yarn 3 has elasticity, the wrapping yarn 3 can be automatically contracted by the elasticity of itself after the hot melt adhesive yarn 2 is melted to be liquid, so as to prevent the falling-off of the pile yarn 4 caused by the loosening of the wrapping yarn 3.
In addition, compared with the first embodiment, the present embodiment has the following disadvantages: because in hot melt adhesive yarn 2 need and the 1 doubling feeding chenille aircraft nose of core yarn, and need guarantee that hot melt adhesive yarn 2 and core yarn 1 butt all the time, then the weaving degree of difficulty is great, at the textile process of chenille aircraft nose, in case hot melt adhesive yarn 2 and the 1 separation contact of core yarn, hot melt adhesive yarn 2 influences the 4 clamp in-between of fine hair yarn very probably and twists the downthehole, finally causes the finished product quality not high.
Example three: referring to fig. 5, the invention discloses a production process for producing lint-free chenille yarn, which comprises the following steps:
A. selecting core yarn 1 with a layer of hot melt adhesive yarn 2 wrapped on the periphery and wrapping yarn 3 made of elastic material; a semi-finished product chenille yarn 51 is produced by a chenille yarn machine head 5, wherein the semi-finished product chenille yarn 51 comprises two core yarns 1 which are parallel to each other and a wool yarn 4 clamped between the core yarns 1;
B. the semi-finished chenille yarn 51 produced by the chenille yarn machine head 5 enters the hollow spindle wrapping mechanism 7, the hollow spindle wrapping mechanism 7 comprises a paying-off hollow pipe 71, a hollow spindle twisting hook 9 connected to the lower end of the paying-off hollow pipe 71 and a driving component 72 for driving the paying-off hollow pipe 71 and the hollow spindle twisting hook 9 to synchronously rotate circumferentially, and the wrapping yarn 3 is wound and wound on the periphery of the paying-off hollow pipe 71; the driving assembly 72 has a plurality of gears, and different gears control the wire laying hollow pipe 71 to rotate at different speeds;
the paying-off hollow pipe 71 and the hollow spindle twisting hook 9 synchronously rotate in the circumferential direction at a high speed, so that the twisting of the semi-finished product chenille yarn 51 is realized; in the rotation process of the paying-off hollow pipe 71, the semi-finished chenille yarn 51 from the hollow spindle twisting hook 9 to the chenille yarn machine head 5 is twisted due to the rotation of the hollow spindle twisting hook 9 at the lower end, and the twist degree depends on the rotation speed of the paying-off hollow pipe 71 and the speed of the output roller 91 (namely the output speed of the core yarn 1 and the wool yarn 4); meanwhile, the fasciated yarn 3 is led out from the periphery sleeved on the paying-off hollow pipe 71 under the guidance of the output roller 91 and passes through the center of the hollow ingot together with the semi-finished product chenille yarn 51; because the fasciated yarn 3 rotates along with the paying-off hollow pipe 71, the fasciated yarn 3 rotates in the same direction and at the same speed at the inlet of the upper end of the paying-off hollow pipe 71 and the position of the hollow spindle twisting hook 9, so that the fasciated yarn 3 does not generate twisting action with the semi-finished chenille yarn 51 at the front section of the hollow spindle twisting hook 9;
after the fasciated yarn 3 and the twisted semi-finished product chenille yarn 51 pass through the hollow spindle twisting hook 9, the back twisting action is generated between the output roller 91 and the hollow spindle twisting hook 9 relative to the front section sliver of the hollow spindle twisting hook 9 due to the rotation of the hollow spindle twisting hook 9; the reverse twist degree is also determined by the rotating speed of the pay-off hollow tube 7 and the speed of the output roller 91, so the twist degrees of the two are the same, but the twist directions are opposite, thus the semi-finished product chenille yarn 51 is untwisted until no twist exists, and meanwhile, the wrapping yarn 3 is twisted with the semi-finished product chenille yarn 51 in the untwisting process, so that the wrapping yarn 3 is wrapped on the periphery of the semi-finished product chenille yarn 51;
C. the assembly of the semi-finished chenille yarn 51 and the wrapping yarn 3 is wound up by the winding mechanism 8.
The implementation principle of the embodiment is as follows: through the steps, the hot melt adhesive yarn 2 can be added between the core yarn 1 and the wool yarn 4, and the molten hot melt adhesive can bond the core yarn 1 and the wool yarn 4 in the later stage spinning process (often needing to pass through a high-temperature environment), so that the falling probability of the wool yarn 4 is greatly reduced;
in the semi-finished product stage of the chenille yarn (only consisting of two core yarns 1 and the wool yarn 4 clamped between the two core yarns 1), the chenille yarn 3 wraps and tightens the chenille yarn to enhance the resisting force of the core yarns 1 and the wool yarn 4 and reduce the falling probability of the wool yarn 4 caused by weaker clamping force of the core yarns 1; and a plurality of twist holes can be formed, the wool yarn 4 can be inserted into each twist hole, and after the processing is finished, the twist holes can reduce the probability of the deviation of the wool yarn 4 along the length direction of the core yarn 1, thereby improving the position stability of the wool yarn 4.
It is worth to be noted that, when the hot melt adhesive yarn 2 on the outer layer of the core yarn 1 is in a liquid state by hot melting, the outer diameter of the core yarn 1 is reduced, and the wrapping yarn 3 becomes loose relative to the wrapping of the core yarn 1, but because the wrapping yarn 3 has elasticity, the wrapping yarn 3 can automatically contract by means of the elasticity of the wrapping yarn 3 after the hot melt adhesive yarn 2 is in the liquid state, so as to prevent the falling-off of the wool yarn 4 caused by the loosening of the wrapping yarn 3;
and because the drive assembly 72 can control the paying-off hollow pipe 71 to rotate at different speeds, when the speed of the output roller 91 is unchanged, the wrapping force of the wrapping yarn 3 can be changed by changing the driving rotating speed of the drive assembly 72 on the paying-off hollow pipe 71, so that the wrapping yarn 3 can be automatically shrunk by means of the elasticity of the hot melt adhesive yarn 2 after the hot melt adhesive yarn 2 is in a liquid state.
In addition, this scheme is compared in current chenille yarn weaving machine, has following three advantages:
1. more electricity-saving: in the original ring mechanism of the ring and the ring twisting hook, the friction between the ring twisting hook and the ring generates a large amount of heat, and the loss of the part of energy occupies at least twenty percent of the total power consumption of the chenille textile machine;
2. the winding efficiency of the finished product chenille yarn is high: because the limit of the steel collar on the rolling outer diameter of the finished product is lost, more chenille yarns can be rolled at one time, and the processing efficiency is improved;
3. the problem of non-uniformity of twist can be avoided: the original chenille yarn twisting is realized by the autorotation of a winding spindle and the traction of the chenille yarn to rotate, and the twist of the chenille yarn is smaller and smaller along with the increasing thickness of the chenille yarn wound to the periphery of the spindle, so that the twist of the whole chenille yarn is uneven, certain twist holes are easy to excessively relax, and the wool yarn is easy to draw out; in the scheme, the two core yarns are false twisted and untwisted through the hollow spindle twisting hook 9, the twisting condition does not exist, the problem of uneven twist degree can not be generated, the wrapping yarn is mainly used for tightening the two core yarns, and the problem of uneven twist degree of the wrapping yarn has little influence on the anti-off velvet of the whole chenille yarn.
Example four: referring to fig. 6, the present embodiment differs from the third embodiment only in step a: selecting wrapping yarn 3 made of elastic material; a semi-finished product chenille yarn 51 is produced by a chenille yarn machine head 5, wherein the semi-finished product chenille yarn 51 comprises two core yarns 1 which are parallel to each other and a wool yarn 4 clamped between the core yarns 1; the two hot melt adhesive yarns 2 are respectively corresponding to one core yarn 1, and each hot melt adhesive yarn 2 is knitted into the semi-finished product chenille yarn 51 along with one core yarn 1 in parallel under the guidance of a first roller 105 or a second roller 106 (see figure 1).
The implementation principle of the embodiment is as follows: the following embodiments are the same as the fourth embodiment, and the only disadvantages are that: because in hot melt adhesive yarn 2 need and the 1 doubling feeding chenille aircraft nose of core yarn, and need guarantee that hot melt adhesive yarn 2 and core yarn 1 butt all the time, then the weaving degree of difficulty is great, at the textile process of chenille aircraft nose, in case hot melt adhesive yarn 2 and the 1 separation contact of core yarn, hot melt adhesive yarn 2 influences the 4 clamp in-between of fine hair yarn very probably and twists the downthehole, finally causes the finished product quality not high.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
