Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber textiles, and more specifically to an elastic close-fitting brocade-viscose fabric. Background Art

[0002] Nylon-viscose fabric is made of yarn made of nylon fiber and yarn made of viscose fiber interwoven together, so it has the advantages of both, being elastic and breathable at the same time.

[0003] However, when used as underwear, the brocade fabric needs to be in direct contact with the body surface and apply elastic force to the body surface. When the brocade fabric is stretched, it will completely fit the body surface, resulting in the inability to discharge sweat produced on the body surface. The accumulation of sweat on the brocade fabric and the body surface will further block the pores on the body surface, causing a feeling of suffocation on the skin surface and causing discomfort to the user. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide an elastic close-fitting brocade-viscose fabric.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: an elastic close-fitting brocade-viscose fabric comprises a first layer and a second layer, wherein the first layer and the second layer are provided with a plurality of through holes one in the thickness direction, and the first layer and the second layer are respectively fixedly connected with a plurality of hollow elastic parts on the opposite surfaces thereof, and the hollow elastic parts are provided with a plurality of through holes two at the connection between the first layer and the second layer, and cloth belts are fixedly connected between the hollow elastic parts, and the hardness of the cloth belts increases at a position away from the hollow elastic parts.

[0006] The utility model is further configured as follows: the projections of the hollow elastic members toward the first layer are staggered.

[0007] The utility model is further configured that: the high hardness points of the cloth belt are treated by hot melt curing.

[0008] The utility model is further configured as follows: the first layer and the second layer include nylon fiber, chitosan fiber, T400 fiber, and viscose fiber.

[0009] The utility model is further configured as follows: the first layer and the second layer include a plurality of warp yarns and a plurality of weft yarns woven with the plurality of warp yarns; the chitosan fiber is parallel to the outside of the nylon fiber and twisted with the nylon fiber to form the warp yarn; the T400 fiber is twisted with the viscose fiber to form the weft yarn.

[0010] The utility model is further configured as follows: the first layer and the second layer are leno tissues and the through holes are obtained through the leno tissues.

[0011] The utility model is further configured as follows: the warp tissue point of the ground tissue of the leno tissue is a fork, the weft tissue point of the ground tissue of the leno tissue is a sink, the warp tissue point of the flower tissue of the leno tissue is a float, and the tissue cycle of the leno tissue is configured from left to right and from bottom to top in sequence: sink, sink, float, sink, float, sink, cross, sink, cross, sink, sink, float, sink, sink, float, sink, sink, float, sink, sink, float, sink, sink, cross, sink, cross, sink, and float.

[0012] In summary, the utility model has the following beneficial effects:

[0013] The elastic close-fitting brocade-viscose fabric of the utility model uses the elastic hollow member between the first layer and the second layer and the elastic force of the cloth belt. When the fabric is stretched, the bent cloth belt is straightened, that is, the cloth belt squeezes the hollow elastic member in the thickness direction of the fabric, so that the position where the hollow elastic member exists in the fabric is raised, which can prevent the fabric from being completely attached to the body surface when the fabric is stretched, thereby increasing the comfort. Through hole one and through hole two are used to increase the air permeability of the fabric when it contacts the body surface, prevent sweating on the body surface, and allow the fabric to be adsorbed on the body surface, further increasing the comfort.

[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Example

[0022] Stretch close fitting brocade viscose fabric, such as Figure 1As shown, it includes a first layer 11 and a second layer 12, and the first layer 11 and the second layer 12 are provided with a plurality of through holes 13 in the thickness direction, and the through holes 13 are distributed along a linear array. The opposite surfaces of the first layer 11 and the second layer 12 are respectively fixedly connected with a plurality of hollow elastic members 14, and the hollow elastic member 14 includes a half hollow sphere, and the plane of the half hollow sphere is fixedly connected to the first layer 11 and the second layer 12 by a polyolefin composite adhesive to form the hollow elastic member 14. In this embodiment, the projection of each hollow elastic member 14 in the direction of the first layer 11 or the second layer 12 completely covers the positions where the two through holes 13 are provided, and the number of through holes 13 between two adjacent hollow elastic members 14 on the same surface is four on each surface, a total of eight, and the number of through holes 13 between two adjacent hollow elastic members 14 on different surfaces is four on each surface, and the number of through holes 13 between two adjacent hollow elastic members 14 on the same surface is eight, and the number of through holes 13 between two adjacent hollow elastic members 14 on different surfaces is eight. The number of through holes 13 between the two hollow elastic members 14 is two, one on each side. The hollow elastic member 14 is provided with two through holes 15 at the connection with the first layer 11 and the second layer 12. The through holes 15 are arranged in a circular array around the hollow elastic member 14. The length of the connection line between the two through holes 15 provided on the same hollow elastic member 14 is equal to the outer diameter of the hollow elastic member 14. The through holes 13 and the through holes 15 increase the air flow inside and outside the fabric, reduce the strength of the hollow elastic member 14 and enhance its deformation ability. A cloth belt 16 is fixedly connected between the hollow elastic members 14. The hollow elastic member 14 itself can resist the force parallel to the thickness direction of the fabric. The hollow elastic member 14 and the cloth belt 16 simultaneously resist the tension of the fabric perpendicular to the thickness direction.

[0023] The hollow elastic member 14 is made of latex material, and the projections of each hollow elastic member 14 toward the first layer 11 are staggered. The cloth tape 16 is made of PP plastic material. The high hardness points 17 of the cloth tape 16 are formed by hot-melt curing treatment using a small hot-melt curing machine, so that the hardness of the cloth tape 16 increases away from the hollow elastic member 14, and the entire cloth tape 16 presents a distribution feature of alternating soft and hard. When the cloth tape 16 is subjected to a force perpendicular to the thickness direction of the fabric, the soft part of the cloth tape 16 tends to be straightened and elongated, and the hard part of the cloth tape 16 remains unchanged.

[0024] The first layer 11 and the second layer 12 include nylon fiber 18, chitosan fiber 19, T400 fiber 20, and viscose fiber 21. The first layer 11 and the second layer 12 include a plurality of warp yarns and a plurality of weft yarns woven with the plurality of warp yarns. The chitosan fiber 19 is parallel to the outer side of the nylon fiber 18 and twisted with the nylon fiber 18 to form the warp yarn. The T400 fiber 20 and the viscose fiber 21 are twisted to form the weft yarn. The fabric made of nylon fiber 18 and viscose fiber 21 has elasticity and breathability. The fabric made of chitosan fiber 19 has the effect of protecting the skin and the advantage of being naturally green. The fabric made of T400 fiber 20 has a high elastic effect.

[0025] like Figure 3As shown, the first layer 11 and the second layer 12 are leno weaves and through holes are obtained through the leno weaves, the warp weave points of the ground weave of the leno weave are forks, the weft weave points of the ground weave are sinks, the warp weave points of the flower weave of the leno weave are floats, and the weave cycle of the leno weave is arranged from left to right and from bottom to top in sequence as: sink-sink-sink-float-sink-float, sink-cross-sink-sink-cross-sink, floating-sink-float-sink-sink, sink-sink-float-sink-float, sink-sink-float-sink-float, sink-sink-sink-float, sink-cross-sink-sink-cross-sink, floating-sink-float-sink-sink, the through holes formed by the leno weave play a breathable role and are suitable for close-fitting use of the fabric.

[0026] During the actual production of the elastic close-fitting brocade-viscose fabric of the present embodiment, the gauze structure is firstly woven by a high-speed rapier loom to form the first layer 11 and the second layer 12, and then the first layer 11 and the second layer 12 are glued on the opposite surfaces by an automatic glue-applying machine to fix the hollow elastic member 14, and the curved surfaces of the hollow elastic member 14 close to each other are glued by the automatic glue-applying machine, and then a plurality of consolidation points are formed on the cloth tape 16 by heat pressing using a hot press, that is, the cloth tape 16 is heat-melted at a plurality of positions on the surface and its elastic properties are reduced by heat pressing, and then the cloth tape 16 is placed on the surface of the hollow elastic member 14 of the second layer 12, and then the side of the first layer 11 where the hollow elastic member 14 exists is covered on the cloth tape 16, so that the hollow elastic members 14 on the first layer 11 and the second layer 12 are staggered, and at the same time, the cloth tape 16 is pulled and the position of the high hardness point is adjusted, and the high hardness point is located between two adjacent hollow elastic members 14, and then a pressing plate is placed on the first layer 11 so that the hollow elastic members 14 14 is in contact with the surface of the cloth belt 16, and the other side of the cloth belt 16 away from the hollow elastic member 14 is in contact with the first layer 11 or the second layer 12, that is, the cloth belt 16 is wavy between the first layer 11 and the second layer 12. After the glue solidifies, the pressing plate is removed to complete the preparation. When the fabric is stretched, the curved cloth belt 16 is straightened, that is, the cloth belt 16 squeezes the hollow elastic member 14 in the thickness direction of the fabric, thereby making the position of the fabric where the hollow elastic member 14 exists bulge, which can prevent the fabric from being completely attached to the body surface when the fabric is stretched, thereby increasing the comfort. At the same time, the hollow elastic member 14 is placed between the first layer 11 and the second layer 12. When the fabric is stretched, the two ends and the middle position of the hollow elastic member 14 are connected to the first layer 11 and the second layer 12 respectively, and the first layer 11 or the second layer 12 located between the two ends of the hollow elastic member 14 will pull the hollow elastic member 14 to stretch, thereby increasing the elastic performance while reducing the deformation, and preventing the use of too hard materials from affecting the comfort of the body surface.

[0027] A through hole 13 is formed on the first layer 11 and the second layer 12 by using a leno weave structure, and the first layer 11 and the second layer 12 processed in one piece increase the performance of the fabric and prevent the fabric from being loose. At the same time, the through hole 13 can increase the air permeability of the fabric, and the through holes 15 at both sides of the hollow elastic member 14 are connected to the through holes 13 on the first layer 11 or the second layer 12, further increasing the air permeability of the fabric to prevent sweat from accumulating on the fabric and the body surface, thereby increasing the comfort of the user;

[0028] The setting of the high hardness points ensures that the distance between two adjacent hollow elastic members 14 changes little when the fabric is stretched, thereby preventing the first layer 11 or the second layer 12 between the two adjacent hollow elastic members 14 from being over-stretched. The hollow elastic members 14 are used as the main source of elastic force, thereby increasing the performance of the fabric. At the same time, the hollow elastic members 14 can also be squeezed to both sides to cause wrinkles on the surface of the fabric, which not only prevents the fabric from being completely adsorbed on the body surface but also allows the wrinkled fabric to change with the changes in the body surface, thereby increasing the wrapping effect of the fabric on the human body and thereby increasing the comfort of use.

[0029] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
