Description

Technical Field

[0001] The invention relates to the technical field of release cloth for pickle ball rackets, in particular to a release cloth for pickle ball rackets. Background Art

[0002] The surface roughness of traditional composite material pickle ball rackets is given by the mold surface in the production process. In order to ensure a good demoulding effect, facilitate mold cleaning and maintenance, and extend the service life of the mold, the contact surface between the mold and the pickle ball racket is smooth and flat. The pickle ball racket using the release cloth adopts the hot pressing molding process. After the pickle ball racket is cured and the release cloth is torn off, a very uniform and neat cloth-grained frosted surface can be formed on the surface of the racket, which can effectively solve the problem of the surface roughness of the racket.

[0003] However, when the prior art is used, when the release cloth is torn off after curing and molding, the peeling force is too large, thereby taking away the surface fibers of the composite product and causing the racket surface to be torn. At the same time, rackets of different materials require different release cloths. The current technology cannot meet different needs and cannot adapt to pickle ball rackets of different materials. Summary of the invention

[0004] The object of the present invention is to provide a release cloth for a pickle ball racket to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A release cloth for a pickleball racket comprises the following production steps: S1, using polyester or nylon filament as raw material; S2, placing the raw materials in step S1 into an atomizing spray structure for water washing, and placing them into a dipping tank for dipping after the water washing is completed; S3, after the dip coating is completed, put it into a drying box for drying; S4, after drying, put it into the thermoforming mold and start the forming operation; S5. After production and forming, it is transferred to the bottom of the cutter through the conveyor line for slitting; S6. Finally, the winding and packaging are completed through the winder.

[0006] Preferably, the polyester or nylon filament raw material in step S1 generally has a linear density of 50-80 Dtex.

[0007] Preferably, the raw material is woven according to a warp and weft density of 30-50 threads / cm, and the weight of the woven fabric is generally 40-90 g / ㎡.

[0009] Preferably, the added coating auxiliary agent A has a concentration of 10%, and the added coating auxiliary agent B has a concentration of 4%.

[0010] Preferably, when slitting is performed in step S5, a Starrett SR 100 (160) surface roughness measuring instrument (or an equivalent instrument) is first used for measurement.

[0011] Preferably, the measured values ​​Rz readings (average maximum height, from top to bottom) roughness deviation ≤ 30 microns (μm), and Rt readings (maximum height, from top to bottom) roughness difference ≤ 40 microns (μm), all readings will be obtained from 4 (6) different directions.

[0012] Preferably, after the determination is completed, multiple types of pickle ball release cloths such as XK50, XK70, and XK90 are finally developed according to the requirements, representing products with gram weights of 50, 70, and 90 g / m2 respectively, and are suitable for pickle ball rackets of different materials.

[0013] Preferably, after the release cloth is produced, the surface roughness of the pickle ball racket is selected based on the yarn density and repeated tests of different weaving warp and weft densities and sent to customers for verification, ultimately meeting customer requirements.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When the present invention is used, polyester or nylon filament raw materials with different densities of 50-80Dtex are woven according to a warp and weft density of generally 30-50 strands / cm, and the woven fabric has a gram weight of generally 40-90g / ㎡, and then washed with water. After the washing is completed, the fabric is placed in a dipping tank to which 10% concentration of auxiliary agent A and 4% concentration of auxiliary agent B have been added and dip-coating is started to solve the problem that the peeling force is too large when the demoulding cloth is torn off after curing and molding, thereby taking away the surface fibers of the composite material product and causing the racket face to be torn.

[0015] At the same time, when the present invention is used, after production and molding, the surface roughness of the racket is selected according to the yarn density and repeated tests of different weaving warp and weft densities and sent to customers for verification, and finally meets the customer's requirements. Specifically, it is measured by using a Starrett SR 100 (160) surface roughness measuring instrument (or equivalent instrument), and the measured value Rz reading (average maximum height, from the top to the bottom) roughness deviation is ≤30 microns (μm), and the Rt reading (maximum height, from the top to the bottom) roughness difference is ≤40 microns (μm). All readings will be obtained from 4 (6) different directions. After the measurement is completed, XK50, XK70, XK90 and other pickle ball release cloths are finally developed according to the requirements, representing products with gram weights of 50, 70, 90 grams / ㎡ respectively, so as to be suitable for pickle ball rackets of different materials, so as to solve the problem that the corresponding racket release cloth cannot be produced to meet the different needs of customers, and thus cannot be suitable for pickle ball rackets of different materials.

[0019] See also Figure 1 The present invention provides a technical solution: a release cloth for a pickleball racket, comprising the following production steps: S1, using polyester or nylon filament as raw material; S2, placing the raw material in step S1 into the atomizing spray structure 1 for water washing, and placing it into the dipping tank 2 for dipping after the water washing; S3, after the dip coating is completed, put it into the drying box 3 for drying; S4, after drying, put it into the thermoforming mold 4 to start the forming operation; S5, after production and forming, it is transferred to the bottom of the cutter 6 through the transmission line 5 for cutting; S6. Finally, the winding and packaging are completed by the winder 7. The release cloth used for the racket can be produced through the above steps.

[0020] In step S1, the polyester or nylon filament raw material generally adopts a linear density of 50-80Dtex, and the raw material is woven according to a warp and weft density of 30-50 strands / cm. The weight of the woven fabric is generally 40-90g / ㎡. In step S2, a coating additive of a relevant concentration is added to the dipping tank 2, and the release cloth is dip-coated. The added coating additive A additive has a concentration of 10%, and the added coating additive B additive has a concentration of 4%. By adding additives A and B, it is possible to avoid excessive peeling force when tearing off the release cloth after curing and molding, thereby taking away the surface fibers of the composite material product and causing the racket face to be torn. After production in step S5, the surface roughness of the racket is selected based on the yarn density and repeated tests of different weaving warp and weft densities and sent to customers for verification, and finally meets the customer's requirements. Specifically, it is measured using a Starrett SR100 (160) surface roughness measuring instrument (or equivalent instrument). The measured value Rz reading (average maximum height, from top to bottom) roughness deviation is ≤30 microns (μm), and the Rt reading (maximum height, from top to bottom) roughness difference is ≤40 microns (μm). All readings will be obtained from 4 (6) different directions. After the measurement is completed, multiple pickle ball release fabrics such as XK50, XK70, and XK90 are finally developed according to the requirements, representing products with gram weights of 50, 70, and 90 grams / ㎡, respectively, so as to be suitable for pickle ball rackets of different materials.

[0021] Working principle: When in use, the polyester or nylon filament raw materials with different densities of 50-80Dtex are woven according to the warp and weft density of 30-50 strands / cm. The weight of the woven fabric is generally 40-90g / ㎡, and then washed. After washing, put it into the dipping tank 2 where 10% concentration of A additive and 4% concentration of B additive have been added to start dipping; After the dip coating is completed, the product is placed in a drying box 3 for drying. After the drying is completed, the product is placed in a thermoforming mold 4 for forming. After production, the surface roughness of the racket is determined based on the yarn density selection and repeated testing of different weaving warp and weft densities and sent to customers for verification, and finally meets the customer's requirements. Specifically, it is measured by using a Starrett SR 100 (160) surface roughness measuring instrument (or equivalent instrument). The measured value Rz reading (average maximum height, from top to bottom) roughness deviation is ≤30 microns (μm), and the Rt reading (maximum height, from top to bottom) roughness difference is ≤40 microns (μm). All readings will be obtained from 4 (6) different directions. After the measurement is completed, XK50, XK70, XK90 and other pickle ball release fabrics are finally developed according to the requirements, representing products with a gram weight of 50, 70, 90 g / ㎡, etc., so as to be suitable for pickle ball rackets of different materials; Finally, the stripping cloth is transferred to the bottom of the cutter 6 for slitting under the action of the transmission line 5, and then the slitting is completed and rolled up and packaged by the winder 7.

[0022] The above operation can avoid excessive peeling force when tearing off the release cloth after curing and molding, thereby taking away the surface fibers of the composite product and causing the racket surface to be torn. At the same time, corresponding racket release cloth can be produced according to the different needs of customers, so as to be suitable for pickle ball rackets of different materials.
