Description

Technical Field

[0001] This utility model relates to the field of textile shrinkage testing technology, specifically to a tooling for testing the water washing shrinkage rate of polyester-viscose woven fabrics. Background Technology

[0002] Polyester-viscose woven fabric, a common textile material, is a blend of polyester and viscose fibers. It combines the strength of polyester with the moisture absorption of viscose and is widely used in clothing, home textiles, and other fields. During textile production and use, the shrinkage rate after washing is a crucial indicator of fabric dimensional stability, directly affecting the quality and performance of the finished product.

[0003] According to CN216160642U, a device for testing the dimensional change rate of textiles after washing is disclosed. This technology discloses a technical solution including "a centrifuge tank, a fixed bearing seat fixedly connected to the top center of the centrifuge tank, a drive motor fixedly connected to the top of the fixed bearing seat, and a drive shaft fixedly connected inside the fixed bearing seat". It has the technical effects of "driving the washing water inside the centrifuge tank to rotate, generating centrifugal force, which accelerates the sedimentation of impurities inside the washing water. After centrifugation, the fresh water is pumped back to the storage tank by a first water pump installed inside the dehydration rate tester through a water collection pipe for resource reuse. After the water inside the centrifuge tank completes centrifugation, the sediment will directly settle in the sedimentation hopper installed at the bottom of the centrifuge tank and be collected through the sedimentation hopper. When sedimentation collection is required, the first and second stop valves are opened, and the sediment is pumped out by a mud pump installed between the first and second stop valves for recycling".

[0004] In the existing technology, the washing shrinkage rate test of polyester-viscose woven fabric usually requires the fabric to be transferred multiple times between the washing equipment and the measuring equipment. This separate testing method is prone to the fabric being stretched or folded during the transfer process, especially when the fabric is wet after washing, which makes it more susceptible to accidental deformation, thus affecting the accuracy of the final shrinkage rate measurement result. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a washing shrinkage rate testing fixture for polyester-viscose woven fabrics. Through the coordinated operation of a flip-up platform and a triangular support frame, the platform is ensured to be stable and level during measurement. The limiting design prevents the support frame from folding back, ensuring measurement accuracy. Combined with magnetic fixation and scale measurement functions, it effectively prevents fabric displacement and achieves fast and accurate measurement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a washing shrinkage test fixture for polyester / viscose woven fabric, comprising a support frame, on which a fixture mechanism is mounted for measuring the washing treatment and dimensional changes of the polyester / viscose woven fabric after washing. The fixture mechanism includes:

[0007] The washing assembly includes a washing tank fixed to the top of a bracket, with a roller rotatably mounted between the left and right ends inside the washing tank, and a driving component on the washing tank for driving the roller to rotate.

[0008] The measuring assembly includes a crossbeam fixed to the front end of the washing tank, with fixed frames at both ends of the left side of the crossbeam, a triangular support frame hinged to the front end of the fixed frame, a cross plate fixed to the top of the crossbeam, a platform hinged to the front end of the cross plate, and pads fixed to both the left and right ends of the bottom of the platform.

[0009] Preferably, the measuring component further includes a stop bar fixed to the bottom of the pad.

[0010] Preferably, the measuring assembly further includes scale lines formed on the edge of the platform surface and a magnetic block magnetically attached to the platform.

[0011] Preferably, the washing assembly further includes a drum cover mounted on the drum, a cover hinged to the upper end of the washing tank, a drain outlet at the bottom of the washing tank, and a control panel mounted on the right end of the washing tank.

[0012] Preferably, the drive component further includes a mounting bracket fixed to the right end of the washing tank, a motor is mounted on the mounting bracket, a drive sprocket is fixed to the output end of the motor, a driven sprocket is fixed to the right end of the drum, a chain is installed between the driven sprocket and the drive sprocket, and a protective cover is fixed on the mounting bracket.

[0013] Preferably, the front end of the fixing frame is hinged to the inner side of the triangular support frame via a hinge, and the bottom of the horizontal plate is pivotally connected to the bottom of the platform via a hinge.

[0014] Beneficial effects

[0015] This invention provides a fixture for testing the shrinkage rate of polyester-viscose woven fabrics after washing. Compared with the prior art, it has the following advantages:

[0016] 1. After washing, rotate the platform upwards by 90 degrees and then rotate the triangular support frame outwards by 90 degrees. This allows the triangular support frame to support the platform, keeping it horizontal and stable, which facilitates fabric measurement. Furthermore, when the triangular support frame is rotated outwards to support the platform, the stop strip and the triangular support frame form a limit, preventing it from accidentally folding inwards due to external force or vibration during measurement. This ensures that the platform remains horizontal and stable at all times, avoiding tilting of the measurement reference plane due to loose support frame, thereby guaranteeing the measurement accuracy after the fabric is laid flat.

[0017] 2. When the washed polyester-viscose woven fabric is laid flat on the measuring table, the magnet can quickly attract and fix the edge of the fabric, effectively preventing the thin fabric from shifting or wrinkling during the measurement process; at the same time, the scale lines directly set on the surface of the measuring table allow the operator to perform size measurements intuitively and quickly.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a testing fixture for the shrinkage rate of polyester / viscose woven fabric after washing, comprising a support 1, characterized in that: a fixture mechanism 2 is provided on the support 1 and used for the washing treatment of polyester / viscose woven fabric and the measurement of dimensional changes after washing, the fixture mechanism 2 comprising:

[0025] The washing assembly 21 includes a washing tank 211 fixed to the top of the bracket 1, a roller 212 rotatably mounted between the left and right ends inside the washing tank 211, and a driving component 214 provided on the washing tank 211 for driving the roller 212 to rotate.

[0026] The measuring component 22 includes a crossbeam 221 fixed to the front end of the washing tank 211. Both ends of the left end of the crossbeam 221 are fixed with a fixing frame 222. A triangular support frame 223 is hinged to the front end of the fixing frame 222. A cross plate 224 is fixed to the top of the crossbeam 221. A platform 225 is hinged to the front end of the cross plate 224. Pads 226 are fixed to the left and right ends of the bottom of the platform 225.

[0027] In this embodiment, after washing, the platform 225 is rotated upward by 90 degrees, and the triangular support frame 223 is rotated outward by 90 degrees, so that the triangular support frame 223 supports the platform 225 and keeps it in a horizontal and stable state, which is convenient for measuring the fabric when it is laid flat. In addition, the cooperation between the pad 226 and the triangular support frame 223 ensures the stability of the platform 225 and prevents the fabric from sliding or deforming during measurement.

[0028] Specifically, the measuring component 22 also includes a stop bar 227 fixed to the bottom of the pad 226.

[0029] In this embodiment, when the triangular support frame 223 is flipped outward to support the platform 225, the stop strip 227 and the triangular support frame 223 form a limit to prevent it from accidentally folding back inward due to external force or vibration during the measurement process; ensuring that the platform 225 always remains in a horizontal and stable state, avoiding the tilting of the measurement reference surface due to the loosening of the support frame, thereby ensuring the measurement accuracy after the fabric is laid flat.

[0030] Specifically, the measuring component 22 also includes scale lines 228 formed on the edge of the surface of the platform 225, and a magnetic block 229 magnetically attached to the platform 225.

[0031] In this embodiment, when the washed polyester-viscose woven fabric is laid flat on the table 225, the magnet 229 can quickly attract and fix the edge of the fabric, effectively preventing the thin fabric from shifting or wrinkling during the measurement process; at the same time, the scale lines 228 directly set on the surface of the table 225 enable the operator to perform size measurement intuitively and quickly.

[0032] Specifically, the washing assembly 21 also includes a drum cover 213 installed on the drum 212, a cover 215 hinged to the upper end of the washing tank 211, a drain outlet 216 provided at the bottom of the washing tank 211, and a control panel 217 installed on the right end of the washing tank 211.

[0033] In this embodiment, the openable and closable drum cover 213 of the drum 212 ensures that the test fabric will not fall off the drum 212 during the washing process, and at the same time facilitates the loading and unloading of samples; the lid 215 hinged at the top of the washing tank 211 forms double protection, effectively preventing the washing liquid from splashing and maintaining a constant temperature environment; the drain outlet 216 at the bottom can quickly drain the washing liquid, which is convenient for cleaning after the test.

[0034] Specifically, the drive component 214 also includes a mounting bracket 2141 fixed to the right end of the washing tank 211. A motor 2142 is mounted on the mounting bracket 2141. A drive sprocket 2143 is fixed to the output end of the motor 2142. A driven sprocket 2144 is fixed to the right end of the roller 212. A chain 2145 is installed between the driven sprocket 2144 and the drive sprocket 2143. A protective cover 2146 is fixed on the mounting bracket 2141.

[0035] In this embodiment, after the fabric is placed inside the drum 212 and water is added to the washing tank 211, the output end of the motor 2142 drives the active sprocket 2143 to work with the chain 2145 to drive the driven sprocket 2144 to rotate. The driven sprocket 2144 drives the drum 212 to roll, thereby washing the fabric.

[0036] Specifically, the front end of the fixed frame 222 is hinged to the inside of the triangular support frame 223 via a hinge, and the bottom of the horizontal plate 224 is pivotally connected to the bottom of the table plate 225 via a hinge.

[0037] The working principle and usage process of this utility model are as follows: First, the fabric is placed inside the drum 212 and water is added to the washing tank 211. Then, the output end of the motor 2142 drives the active sprocket 2143 to cooperate with the chain 2145 to drive the driven sprocket 2144 to rotate. The driven sprocket 2144 drives the drum 212 to roll, thereby washing the fabric.

[0038] After washing, the platform 225 is rotated upwards by 90 degrees, and the triangular support frame 223 is rotated outwards by 90 degrees, so that the triangular support frame 223 supports the platform 225 and keeps it in a horizontal and stable state, which is convenient for measuring the fabric when it is laid flat.

[0039] Finally, when the washed polyester-viscose woven fabric is laid flat on the table 225, the magnet 229 can quickly attract and fix the edge of the fabric, effectively preventing the thin fabric from shifting or wrinkling during the measurement process; at the same time, the scale lines 228 directly set on the surface of the table 225 allow the operator to perform size measurements intuitively and quickly.
