Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textiles, and in particular discloses an adaptive elastic Lycra belt and clothes with the elastic Lycra belt. Background Art
[0002] Lycra is DuPont's registered trademark for spandex, so Lycra is also known as spandex fiber. Spandex fiber's high elasticity stems from its polymer chains, which are composed of low-melting, amorphous "soft" segments embedded within high-melting, crystalline "hard" segments. The soft segments are cross-linked to form a network structure. Due to the low interchain interactions, the flexible segments can expand and contract freely, resulting in high elongation. The rigid segments, however, have strong molecular bonds, preventing them from expanding indefinitely, resulting in high resilience.
[0003] As the tensile deformation of existing spandex fibers increases, the rebound force also increases accordingly. It is difficult for wearers of different body shapes to choose their own size, and the fiber is not inclusive. The performance cannot be flexibly adjusted at any time according to the wearer's needs. At the same time, when worn for a long time, the wearer feels restrained and the user experience is poor. Utility Model Content
[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide an elastic Lycra belt and clothing whose rebound force changes with the use state, whose performance can be flexibly adjusted according to the wearer's needs, which is highly inclusive and fits the body shape.
[0005] To achieve the above objectives, the present invention provides an adaptive elastic Lycra belt comprising a first fabric layer, a second fabric layer, and a Lycra stretch layer. The Lycra stretch layer is positioned between the first and second fabric layers. The Lycra stretch layer comprises a knitted structure woven from adaptive fibers, and both the first and second fabric layers comprise a knitted structure woven from first fibers. When the adaptive fibers are stretched, the adaptive fibers adjust their resilience. The present invention enhances the adaptability of the Lycra stretch belt by using adaptive fibers. When the wearer is at rest, the adaptive fibers adjust their resilience to provide a suitable fit, shape, and control. When the wearer is in motion, the adaptive fibers adjust their resilience to provide suitable dynamic comfort, significantly reducing restraint on the body.
[0006] Furthermore, the lycra stretch layer has a six-way, one-loop knit structure, including a first, second, third, fourth, fifth, and sixth loops. The first loop is knitted with a first adaptive fiber in a looping, tucking, and surfacing process in the lower needle cylinder. The second, third, fourth, fifth, and sixth loops are knitted with a second adaptive fiber in a looping process in the lower needle cylinder. By configuring a six-way, one-loop structure and incorporating the first and second adaptive fibers in different patterns, the woven lycra stretch layer features continuously arranged small holes, enhancing breathability. This also makes the lycra stretch layer lighter and thinner, significantly reducing its binding force on the body.
[0007] Furthermore, the adaptive fiber includes a first core yarn and a covering layer, and the covering layer is an aqueous polyurethane dispersion. The aqueous polyurethane dispersion improves the compression modulus of the adaptive fiber during stretching, making the resilience of the adaptive fiber relatively constant, solving the problem that the resilience of the spandex fiber increases with the increase in tensile deformation, thereby improving the inclusiveness of the Lycra elastic band.
[0008] Furthermore, the first core yarn is Lycra spandex. Its excellent lightness and elastic recovery greatly reduce the restraint on the human body, allowing the wearer to experience "zero" wearing sensation. Lycra spandex also has good shape retention, maintaining the original state of the Lycra stretch band, and has a longer service life than traditional stretch bands.
[0009] Furthermore, the single strand specification of the lycra spandex is 20-30D. When the lycra elastic band woven with the lycra spandex of this specification is worn on the body, it can be felt that the weight is small, and it has good air permeability and good elasticity.
[0010] Furthermore, the first fiber includes a second core yarn and a wrapping yarn wrapped around the outside of the second core yarn, wherein the second core yarn is Lycra spandex and the wrapping yarn is nylon yarn. By using nylon yarn, the feel and wearing comfort of the first and second fabric layers can be improved while ensuring the moisture absorption and perspiration removal capabilities.
[0011] Furthermore, a flocking layer is provided on the first fabric layer and / or the second fabric layer. The flocking layer has a comfortable feel, gives the user a skin-friendly, soft and comfortable feeling, enhances the user's physical experience, and has anti-slip properties, and is not easy to shift during exercise.
[0012] A garment using the above-mentioned adaptive elastic lycra belt comprises a garment body, the garment body is provided with a tightening portion, and the adaptive elastic lycra belt is arranged on the tightening portion.
[0013] Furthermore, the clothing is underwear, panties or body shaping garments.
[0014] The beneficial effects of the present invention are as follows: the present invention enhances the adaptability of the Lycra elastic band through the Lycra elastic band woven with adaptive fibers. When the wearer is in a resting state, the adaptive fibers adjust the rebound force to provide appropriate fit, shape and control force; when the wearer is in motion, the adaptive fibers adjust the rebound force to provide appropriate dynamic comfort, greatly reducing the restraint on the human body; by setting six routes and one loop, and weaving the first adaptive fibers and the second adaptive fibers in different forms, the woven Lycra elastic layer can have continuously arranged small holes, thereby increasing the breathability; at the same time, the Lycra elastic layer is made lighter and thinner, greatly reducing the restraint on the human body.

[0022] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0023] See also Figures 1 to 5As shown, the present invention provides an adaptive elastic Lycra belt, comprising a first fabric layer 1, a second fabric layer 2, and a Lycra stretch layer 3. The Lycra stretch layer 3 is positioned between the first and second fabric layers 1 and 2. The Lycra stretch layer 3 has a knitted structure woven from adaptive fibers, while both the first and second fabric layers 1 and 2 have knitted structures woven from first fibers. When the adaptive fibers are stretched, the adaptive fibers adjust their resilience. This invention enhances the adaptability of the Lycra belt by using adaptive fibers. When the wearer is resting, the adaptive fibers adjust their resilience to provide a suitable fit, shape, and control. When the wearer is in motion, the adaptive fibers adjust their resilience to provide suitable dynamic comfort, significantly reducing restraint on the body.
[0024] The lycra stretch layer 3 is knitted in a six-way, one-loop structure, comprising a first loop 10, a second loop 11, a third loop 12, a fourth loop 13, a fifth loop 14, and a sixth loop 15. The first loop 10 is knitted with the first adaptive fiber 4 in a looping, tucking, and surfacing pattern on the lower needle. The second loop 11, the third loop 12, the fourth loop 13, the fifth loop 14, and the sixth loop 15 are knitted with the second adaptive fiber 5 in a looping pattern on the lower needle. This six-way, one-loop structure, along with the different patterns of first and second adaptive fibers 4 and 5, ensures that the woven lycra stretch layer 3 has continuously arranged small holes, enhancing breathability. This also makes the lycra stretch layer 3 lighter and thinner, significantly reducing its binding force on the body.
[0025] The adaptive fiber includes a first core yarn 6 and a covering layer 7. The covering layer 7 is an aqueous polyurethane dispersion. The aqueous polyurethane dispersion improves the compression modulus of the adaptive fiber during stretching, making the resilience of the adaptive fiber relatively constant, solving the problem that the resilience of the spandex fiber increases with the increase in tensile deformation, thereby improving the inclusiveness of the Lycra elastic band.
[0026] In a further technical solution, the aqueous polyurethane dispersion refers to a composition containing at least a polyurethane or polyurethane urea polymer or prepolymer.
[0027] In a further embodiment, the prepolymer comprises ethylene glycol, an aliphatic diisocyanate, and a diol, wherein the ratio of isocyanate groups in the aliphatic diisocyanate to hydroxyl groups in the ethylene glycol and the diol (NCO / OH) is about 1.30 to about 2.20.
[0028] In a further technical solution, the aqueous polyurethane dispersion is solidified or dried to form and wrap the first core yarn 6 .
[0029] The first core yarn 6 is made of Lycra spandex. Its excellent lightness and elastic recovery greatly reduce the restraint on the human body, allowing the wearer to experience "zero" wearing sensation. Furthermore, Lycra spandex has good shape retention, which can maintain the original state of the Lycra elastic band. Compared with traditional elastic bands, it has a longer service life.
[0030] The single strand specification of the lycra spandex is 20-30D. When the lycra elastic band woven with the lycra spandex of this specification is worn on the body, the weight that can be felt is small, and the air permeability and elasticity are good.
[0031] In this embodiment, the single strand specification of the Lycra spandex is 20D.
[0032] The first fiber includes a second core yarn 8 and a wrapping yarn 9 wrapped around the outside of the second core yarn 8. The second core yarn 8 is Lycra spandex and the wrapping yarn 9 is nylon yarn. By using nylon yarn, the hand feel and wearing comfort of the first fabric layer 1 and the second fabric layer 2 can be improved while ensuring the moisture absorption and perspiration removal ability.
[0033] A flocking layer is provided on the first fabric layer 1 and / or the second fabric layer 2. The flocking layer feels comfortable, gives the user a skin-friendly, soft and comfortable feeling, enhances the user's physical experience, and has anti-slip properties and is not easy to shift during exercise.
[0034] A garment using the above-mentioned adaptive elastic lycra belt comprises a garment body, the garment body is provided with a tightening portion, and the adaptive elastic lycra belt is arranged on the tightening portion.
[0035] The tightening portion is where the clothes fit and are fixed to the wearer.
[0036] The clothing is underwear, panties or body shaping garments.
[0037] In actual use, the first adaptive fiber 4 is formed by wrapping Lycra spandex with aqueous polyurethane dispersion, and the second adaptive fiber 5 is composed of Lycra spandex and cotton nylon yarn wrapped on the outside of the Lycra spandex. The first adaptive fiber 4 and the second adaptive fiber 5 are woven into a Lycra elastic belt in a six-way and one-cycle manner to enhance the adaptability of the Lycra elastic belt. When the wearer is at rest, the adaptive fiber adjusts the rebound force to provide appropriate fit, shape and control; when the wearer is in motion, the adaptive fiber adjusts the rebound force to provide appropriate dynamic comfort, greatly reducing the restraint on the human body, making it easy to put on and take off, and allowing the wearer to feel "zero" wearing feeling.
[0038] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
