Description

Technical Field

[0001] The present invention relates to the technical field of textiles, and in particular to a velvet sheath fabric that does not fall off and a weaving method thereof. Background Art

[0002] Since velvet fabrics are soft and the velvet hairs can form an air layer with good heat preservation effect, therefore, using velvet fabrics with weft elasticity to make velvet sheaths, namely knee protectors and elbow protectors, is very popular; however, after a long time, when the weft elasticity is gradually damaged, these knee protectors and elbow protectors will gradually fall off due to human activities, and finally become a cumbersome thing that is a pity to discard and troublesome to use. For such a good heat preservation sheath, people hope that it can "stay young forever" and not fall off, and people really hope so. Summary of the Invention

[0003] The main purpose of the present invention is to research and develop a velvet sheath fabric that does not fall off and a weaving method thereof to meet the market needs and the voices of customers.

[0004] To achieve the above object, a technical solution adopted by the present invention is: to provide a velvet sheath fabric that does not fall off, including:

[0005] The velvet sheath fabric that does not fall off is jointly woven by a fabric layer with one-way friction downward on one side and a velvet layer with the velvet hairs inclined downward on one side;

[0006] And the fabric layer is divided into an upper fabric layer and a lower fabric layer during weaving;

[0007] The upper fabric layer is formed by warp and weft interlacing of a first upper warp yarn, a second upper warp yarn, a third upper warp yarn, an upper first upper weft yarn, a second upper weft yarn, a third upper weft yarn, a fourth upper weft yarn, a fifth upper weft yarn, a sixth upper weft yarn, a seventh upper weft yarn, an eighth upper weft yarn, a ninth upper weft yarn and a tenth upper weft yarn;

[0008] The lower fabric layer is formed by warp and weft interlacing of a first lower warp yarn, a second lower warp yarn, a third lower warp yarn, a lower first lower weft yarn, a second lower weft yarn, a third lower weft yarn, a fourth lower weft yarn, a fifth lower weft yarn, a sixth lower weft yarn, a seventh lower weft yarn, an eighth lower weft yarn, a ninth lower weft yarn and a tenth lower weft yarn;

[0009] Further, the first upper warp yarn, the second upper warp yarn, the first lower warp yarn and the second lower warp yarn are tight warp yarns;

[0010] Further, the third upper warp yarn and the third lower warp yarn are loose warp yarns, and the tight-loose ratio is 1:0.9;

[0011] Further, the first upper weft yarn, the second upper weft yarn, the fourth upper weft yarn, the fifth upper weft yarn, the sixth upper weft yarn, the seventh upper weft yarn, the ninth upper weft yarn, the tenth upper weft yarn, the first lower weft yarn, the second lower weft yarn, the fourth lower weft yarn, the fifth lower weft yarn, the sixth lower weft yarn, the seventh lower weft yarn, the ninth lower weft yarn, and the tenth lower weft yarn are elastic fine weft yarns;

[0012] Further, the third upper weft yarn, the eighth upper weft yarn, the third lower weft yarn, and the eighth lower weft yarn are elastic thick weft yarns, and the thickness ratio is 1:0.6;

[0013] The fluff layer is formed by the first pile warp and the second pile warp consolidating and weaving the upper fabric layer and the lower fabric layer and connecting them. It is cut open by a pile cutting knife between the upper fabric layer and the lower fabric layer, leaving the consolidated pile heads on the upper fabric layer and the lower fabric layer to form the fluff layer;

[0014] Further, in the weaving of the fabric layer where the tight warp yarns, loose warp yarns, and weft yarns are interwoven, since one of them is a thick weft yarn, sawtooth-shaped protrusions are generated on the surface of the fabric layer to form a fabric surface with unidirectional friction;

[0015] Further, in the weaving of the fluff layer where the tight warp yarns, loose warp yarns, and weft yarns are interwoven, due to the use of the tight warp yarns and loose warp yarns, the pile warp is squeezed by the weft yarns at different heights during the consolidation weaving with the fabric layer, causing the fluff to tilt, and thus forming a fluff layer with unidirectional tilt;

[0016] Due to the friction, it thus becomes a velvet sheath fabric that does not fall off.

[0017] The present invention also provides a weaving method for a velvet sheath fabric that does not fall off, specifically including the following steps:

[0065] IV. Post-treatment of cut velvet;

[0066] So far, the weaving of a velvet sheath fabric that will not fall off according to the present invention is completed.

[0067] The beneficial effects of the present invention are:

[0068] 1. A velvet sheath fabric of the present invention that does not fall off. Due to the weaving of the fabric layer with tight warp yarns, loose warp yarns, thick weft yarns, and thin weft yarns, in the order of shuttle throwing, from the second (seventh) elastic thin weft yarn obliquely to the third (eighth) elastic thick weft yarn outside the second tight warp yarn, and then directly reaching the fourth (ninth) elastic thin weft yarn inside the second tight warp yarn, it is surrounded by the third loose warp yarn to form an angle similar to a zigzag, causing countless small zigzag protrusions to appear on the surface of the fabric layer, thus forming a fabric surface with a unidirectional frictional force in the right direction.

[0069] 2. A weaving method of a velvet sheath fabric of the present invention that does not fall off. Among them, in the weaving of the pile warp with the tight warp yarns, loose warp yarns, and weft yarns, since the fabric layer uses the first tight warp yarn and the second tight warp yarn, the weft yarn has the first weft yarn between the second tight warp yarn and the first tight warp yarn in the ground tissue, the second weft yarn and the third weft yarn above the first tight warp yarn, the fourth weft yarn between the second tight warp yarn and the first tight warp yarn, and the fifth weft yarn below the second tight weft yarn; this is equivalent to having three dimensions of weft yarn diameters, enabling the first pile warp to be fixedly woven with the middle first weft yarn, fourth weft yarn, and fifth weft yarn during the fixation weaving with the fabric layer; similarly, since the fabric layer uses the first tight warp yarn and the second tight warp yarn, the weft yarn has the sixth weft yarn between the second tight warp yarn and the first tight warp yarn in the ground tissue, the seventh weft yarn and the eighth weft yarn above the first tight warp yarn, the ninth weft yarn between the second tight warp yarn and the first tight warp yarn, and the tenth weft yarn below the second tight weft yarn; this is equivalent to having three dimensions of weft yarn diameters, enabling the second pile warp to be fixedly woven with the middle sixth weft yarn, ninth weft yarn, and tenth weft yarn during the fixation weaving with the fabric layer. Taking the pile head of the fifth weft yarn exposed on the fabric layer as an example, it is squeezed by the sixth weft yarn; since the sixth weft yarn is higher than the fifth weft yarn, the pile head of the fifth weft yarn exposed will tilt to the right due to the extrusion of the sixth weft yarn. At the same time, the pile head of the sixth weft yarn exposed by the first pile warp is directly squeezed by the fifth weft yarn lower than the sixth weft yarn and tilts to the right. By the same principle, other pile heads also tilt to the right for this reason.

[0070] 3. A velvet sheath fabric of the present invention that does not fall off. The fabric layer has a unidirectional frictional force to the right in the zigzag direction to the right, and the pile layer has a unidirectional frictional force to the right with the pile tilting to the right; therefore, making a velvet sheath with the fabric of the present invention, plus the elastic effect, will not fall off and can "remain youthful forever", being deeply loved by people.

Embodiment

[0076] This embodiment provides a velvet sheath fabric that will not fall off and its weaving method, as Figure 1 and Figure 2 shown, including:

[0077] The velvet sheath fabric is composed of a velvet layer on one side and a fabric layer on the other side combined;

[0078] More specifically, the velvet sheath fabric is woven by combining a fabric layer with a one-way frictional force downward on one side and a velvet layer with the velvet inclined downward on the other side;

[0079] And the fabric layer is divided into an upper fabric layer and a lower fabric layer during weaving;

[0080] The upper fabric layer is formed by the warp and weft interweaving of the first upper warp yarn, the second upper warp yarn, the third upper warp yarn, the first upper weft yarn, the second upper weft yarn, the third upper weft yarn, the fourth upper weft yarn, the fifth upper weft yarn, the sixth upper weft yarn, the seventh upper weft yarn, the eighth upper weft yarn, the ninth upper weft yarn, and the tenth upper weft yarn;

[0081] The lower fabric layer is formed by the interweaving of warp and weft yarns, including the first lower warp yarn, the second lower warp yarn, the third lower warp yarn, the first lower weft yarn, the second lower weft yarn, the third lower weft yarn, the fourth lower weft yarn, the fifth lower weft yarn, the sixth lower weft yarn, the seventh lower weft yarn, the eighth lower weft yarn, the ninth lower weft yarn, and the tenth lower weft yarn;

[0082] Further, the first upper warp yarn, the second upper warp yarn, the first lower warp yarn, and the second lower warp yarn are tight warp yarns;

[0083] Further, the third upper warp yarn and the third lower warp yarn are loose warp yarns, and the tight-loose ratio is 1:0.9;

[0084] Even further, the first upper weft yarn, the second upper weft yarn, the fourth upper weft yarn, the fifth upper weft yarn, the sixth upper weft yarn, the seventh upper weft yarn, the ninth upper weft yarn, the tenth upper weft yarn, the first lower weft yarn, the second lower weft yarn, the fourth lower weft yarn, the fifth lower weft yarn, the sixth lower weft yarn, the seventh lower weft yarn, the ninth lower weft yarn, and the tenth lower weft yarn are elastic fine weft yarns;

[0085] Even further, the third upper weft yarn, the eighth upper weft yarn, the third lower weft yarn, and the eighth lower weft yarn are elastic thick weft yarns, and the thick-thin ratio is 1:0.6;

[0086] The fluff layer is formed by the first pile warp and the second pile warp often consolidating and connecting the upper fabric layer and the lower fabric layer during weaving. Then, it is cut by a pile cutting knife in the middle between the upper fabric layer and the lower fabric layer, leaving the consolidated pile heads on the upper fabric layer and the lower fabric layer to form the fluff layer;

[0087] Further, in the weaving of the fabric layer with the tight warp yarns, loose warp yarns, and weft yarns, since there is one thick weft yarn among them, sawtooth-shaped protrusions are formed on the surface of the fabric layer, resulting in a fabric surface with unidirectional friction;

[0088] Further, in the weaving of the fluff layer with the tight warp yarns, loose warp yarns, and weft yarns, due to the use of tight warp yarns and loose warp yarns, the pile warp is squeezed by the weft yarns at different heights during the consolidation weaving with the fabric layer, causing the fluff to tilt, and thus forming a fluff layer with a unidirectional tilt;

[0089] Due to the frictional effect, it thus becomes a velvet sheath fabric that does not fall off;
