Description

Technical Field

[0001] The invention belongs to the technical field of clothing fabric preparation, and in particular relates to a graphene cashmere fabric wrinkle resistance experimental device. Background Art

[0002] Graphene cashmere fabric is a novel material composited from cashmere and graphene. Cashmere, a high-grade animal fiber, originates from the fine, soft down at the base of goat hair. Its excellent warmth and soft feel have earned it the nickname "soft gold." Graphene, a two-dimensional carbon material, is renowned for its exceptional electrical and thermal conductivity and structural stability. Combining these two materials through a specialized process retains the warmth and softness of cashmere while imparting novel properties such as antistatic, antibacterial, and wrinkle resistance. Graphene's toughness and structural stability help the fabric maintain its shape despite external forces, giving cashmere fabric excellent wrinkle resistance and keeping clothing neat and smooth.

[0003] During the production of graphene cashmere fabric, an anti-wrinkle performance test device is required to determine the fabric's anti-wrinkle performance. However, existing fabric anti-wrinkle performance test devices are relatively incomplete. They can generally only simulate fabric wrinkles through folding and other measures, and determine the fabric's anti-wrinkle performance by measuring the crease recovery angle. However, it is difficult to truly reflect the fabric's anti-wrinkle performance during wear. In addition, the existing fabric anti-wrinkle performance test device has poor experimental efficiency, making it difficult to conduct simultaneous experiments on multiple fabric samples and difficult to adapt to the use of fabric samples of different specifications.

[0004] To this end, we provide a graphene cashmere fabric anti-wrinkle performance experimental device to solve the above problems. Summary of the Invention

The reel assembly comprises two rotating plates rotatably arranged in the semicircular groove on the top surface of the chassis and a plurality of reel bodies rotatably arranged between the two rotating plates and evenly distributed along the circumference. The reel body comprises two semi-cylinders and a magnetic coupling for connecting the two semi-cylinders. The reverse rotation of the two rotating plates is used to simulate the human body twisting the fabric. The interior of the semi-cylinder is provided with a pulling experimental unit for simulating the human body pulling the fabric.

[0010] As a further optimization scheme of the present invention, the outer side surface of the vacuum adsorption plate is set to be an arc surface and matches the outline of the semi-cylinder. A plurality of adsorption holes distributed at equal intervals are provided on the arc surface, and a main channel connected to the plurality of adsorption holes is provided inside the vacuum adsorption plate.

[0011] As a further optimization scheme of the present invention, a slide groove is provided in the middle of each adsorption hole, and a magnetic plate for adjusting the opening and closing of the adsorption hole is slidably provided in the slide groove; magnetic blocks that are attracted to the magnetic plate are fixed at both ends of the slide groove, and the magnetic plate is provided with a through hole that matches the adsorption hole.

[0015] As a further optimization solution of the present invention, a plurality of gas pipes distributed at equal intervals for inputting gas with the temperature and humidity required for the experiment are provided on the inner wall of the semicircular cover.

[0021] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1 To solve the problems of poor comprehensiveness of existing fabric anti-wrinkle performance test equipment, difficulty in simulating the wrinkles caused by human body movement in actual wearing, and difficulty in conducting simultaneous tests on multiple fabric samples, please refer to Figure 1 A graphene cashmere fabric wrinkle resistance test device comprises a chassis 1 and a reel assembly 2, located within a semicircular groove on its top surface, for winding cashmere fabric. A wrinkle detection assembly 3, which uses 3D scanning technology to quantify wrinkle levels, is located to the side of reel assembly 2. A transparent semicircular cover 4, hinged to the top of chassis 1, covers reel assembly 2. The graphene cashmere fabric to be tested is wrapped around reel assembly 2, which simulates human body twisting of the fabric. The wrinkle detection assembly 3 then quantifies the degree of wrinkles, significantly improving the convenience and accuracy of cashmere fabric wrinkle resistance testing.

[0023] like Figure 2-4 As shown, the reel assembly 2 includes two rotating plates 201 rotatably arranged in the semicircular grooves on the top surface of the chassis 1 and a plurality of reel bodies 202 rotatably arranged between the two rotating plates 201 and evenly distributed along the circumference; both sides of the chassis 1 are provided with a first driving unit 203 for driving the respective rotating plates 201 to rotate, and the rotating plates 201 are provided with a plurality of second driving units 204 for driving the respective reel bodies 202 to rotate, and the first driving unit 203 and the second driving unit 204 are both configured as motors. 2 includes two half-cylinders 202a and a magnetic coupling 202b for connecting the two half-cylinders 202a. The magnetic coupling 202b is an electromagnetic magnetic coupling. Fixed clamps 202c for clamping the ends of the cashmere fabric are symmetrically provided in the grooves on both sides of the half-cylinder 202a. A vacuum adsorption plate 202d fixedly connected to the pulling test unit 202e is provided in the notch on one side of the half-cylinder 202a. The outer surface of the vacuum adsorption plate 202d is designed as a curved surface and matches the contour of the half-cylinder 202a.

[0024] When testing a large sample of fabric, it is wound onto multiple reel bodies 202, and the ends of the fabric are clamped by fixing clamps 202c. Then the magnetic coupling 202b is disconnected, and the first drive unit 203 is used to drive the respective rotating plates 201 to rotate. The rotating plates 201 drive the semi-cylinders 202a thereon to rotate. The two rotating plates 201 rotate in opposite directions to simulate the human body twisting the fabric. After a period of time, the fabric is reset to allow it to recover naturally. The wrinkles are quantified by the wrinkle detection component 3 to simulate the wrinkles caused by human body movement during actual wearing and evaluate its wrinkle resistance.

[0025] When testing large sample fabrics, the following anti-wrinkle test can also be carried out. The fabric is wound onto multiple roll bodies 202, and the ends of the fabric are clamped by the fixing clamps 202c. Then, the magnetic coupling 202b is started, and the fabric is adsorbed by the vacuum adsorption plate 202d. The second drive unit 204 drives each roll body 202 to rotate. Multiple roll bodies 202 are twisted at the same time, and reset after a period of time to allow the fabric to recover naturally. The wrinkles are quantified by the wrinkle detection component 3 to simulate the wrinkle resistance of the fabric when it is twisted in multiple parts.

[0026] When testing small sample fabrics, multiple small sample experiments can be carried out at the same time. The fabrics are wound onto their respective reel bodies 202, and the ends of the fabrics are clamped by the fixing clamps 202c. Then the magnetic coupling 202b is disconnected, and the second driving unit 204 is used to drive the respective half-cylinders 202a to rotate. The two half-cylinders 202a of the same reel body 202 rotate in opposite directions to simulate the human body twisting the fabric. After a period of time, the fabric is reset to allow it to recover naturally, and the wrinkles are quantified by the wrinkle detection component 3. like Figure 6 As shown, the wrinkle detection assembly 3 includes a mounting plate 301 and a 3D scanning head 302 fixed to the mounting plate 301. A second movable module 303, which can be a lead screw module, is fixed to the top of the chassis 1 and is used to drive the 3D scanning head 302 along the axial direction of the reel assembly 2. The second movable module 303 drives the 3D scanning head 302 to move. The 3D scanning head 302 captures the surface of the fabric, measuring indicators such as surface roughness and texture changes to quantify the degree of wrinkles.

[0027] like Figure 1 As shown, the inner wall of the semicircular cover 4 is provided with multiple equally spaced gas pipes 401 for inputting the temperature and humidity gas required for the experiment. The semicircular cover 4 can create a closed space, so that the cashmere fabric is under the required temperature and humidity conditions, simulating the anti-wrinkle effect under different temperature and humidity conditions.

[0028] Example 2 On the basis of Example 1, in order to further improve the comprehensiveness of the fabric anti-wrinkle performance experiment, the human body pulling the fabric is simulated. Figure 4-Figure 5 As shown, a pulling experimental unit 202e for simulating human body pulling fabric is provided inside the semi-cylinder 202a; the pulling experimental unit 202e includes a first cylinder 202e-1 and a first movable module 202e-2 that drives the first cylinder 202e-1 to move axially along the semi-cylinder 202a; the piston rod end of the first cylinder 202e-1 is fixedly connected to the inner side surface of the vacuum adsorption plate 202d, and the first movable module 202e-2 is fixedly arranged in the inner cavity of the semi-cylinder 202a. The fabric is adsorbed by the vacuum adsorption plate 202d, and then the first cylinder 202e-1 is extended and retracted to simulate the human body pulling the fabric inward and outward. After a period of time, the vacuum adsorption plate 202d is closed to allow the fabric to recover naturally, and the wrinkles are quantified by the wrinkle detection component 3; when the first cylinder 202e-1 is driven by the first movable module 202e-2 to move axially along the semi-cylinder 202a, the first cylinder 202e-1 drives the fabric to move, simulating the human body pulling the fabric to both ends. After a period of time, the vacuum adsorption plate 202d is closed to allow the fabric to recover naturally, and the wrinkles are quantified by the wrinkle detection component 3.

[0029] In order to improve the adaptability of the vacuum adsorption plate 202d to samples of different specifications, a plurality of equally spaced adsorption holes 202d-1 are provided on the arc surface of the vacuum adsorption plate 202d, and a main channel 202d-2 connected to the plurality of adsorption holes 202d-1 is provided inside the vacuum adsorption plate 202d; a slide groove 202d-3 is provided in the middle of each adsorption hole 202d-1, and a magnetic plate 202f for adjusting the opening and closing of the adsorption hole 202d-1 is slidably provided in the slide groove 202d-3; magnetic blocks 202g that are attracted to the magnetic plate 202f are fixed at both ends of the slide groove 202d-3, and a through hole 202f-1 matching the adsorption hole 202d-1 is provided on the magnetic plate 202f. Based on actual needs, the magnetic plate 202f is driven to move by an external magnet, and the adsorption hole 202d-1 is closed or opened by the magnetic plate 202f. If it is necessary to perform a stretching test on both ends of multiple small samples wrapped around the reel body 202, the ends of the fabric are adsorbed through the adsorption hole 202d-1, and then the multiple small samples are driven to move at the same time by the vacuum adsorption plate 202d, thereby completing the simultaneous pulling test of multiple small samples.

[0030] Example 3 On the basis of Example 1 and Example 2, in order to further improve the comprehensiveness of the fabric anti-wrinkle performance experiment, the human body rubbing the fabric is simulated. Figure 6As shown, the wrinkle detection assembly 3 is equipped with a rubbing test unit 304 for simulating a human body rubbing a fabric. This rubbing test unit 304 comprises a second cylinder 304a fixed to the mounting plate 301 and a rubbing block 304b fixed to the end of the piston rod of the second cylinder 304a. During use, the second moving module 303 drives the mounting plate 301 to continuously move back and forth, which in turn drives the rubbing test unit 304 to continuously move back and forth. The rubbing block 304b continuously rubs the fabric back and forth. After a period of time, the fabric is allowed to recover naturally, and wrinkles are quantified by the wrinkle detection assembly 3.

[0031] The above embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and such modifications and improvements are all within the scope of protection of the present invention.
