Description

Technical Field

[0001] This invention relates to the field of wiping materials technology, and in particular to a composite fiber wiping cloth and its preparation method. Background Technology

[0002] In glass processing, especially in the post-processing of coated glass, dirt (such as dust and particles) and oil layers from the coating easily remain on the glass surface, requiring cleaning through wiping. Currently, commonly used wiping cloths are mostly pure fiber cloths (such as cotton or synthetic fiber cloths), which have insufficient cleaning ability. For example, patent document CN108697955 A, entitled "Nonwoven Cleaning Substrate," discloses a nonwoven cleaning substrate. The nonwoven material has a layered structure and may include adhesive additives. Nonwoven materials can be used to attract and collect particles and can improve cleaning efficiency. Alternatively, wiping cloths made of rigid materials can be used.

[0003] However, while the aforementioned purely flexible fiber wiping cloths offer good flexibility and are less likely to scratch the glass, their cleaning ability for stubborn dirt on the glass surface is insufficient. Repeated wiping is often necessary, reducing cleaning efficiency and potentially causing micro-abrasion on the glass surface due to repeated friction. This is particularly problematic for coated glass, where the coating layer is poorly protected and prone to wear and peeling. Hard wiping materials offer strong cleaning power and can remove stubborn dirt, but their high hardness makes them highly susceptible to scratching the glass surface during wiping, resulting in scratches, cracks, and other defects. For coated glass, this can directly damage the coating layer, leading to product scrap and severely impacting product quality and production efficiency. Therefore, there is a need to develop a newer technological design utilizing a composite woven structure of metal and flexible fibers to remove stubborn organic spot, clump, and linear dirt remaining on the glass surface after coating without scratching the glass surface or the coating layer. This would solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a composite fiber wiping cloth and its preparation method to solve the problems in the above-mentioned background technology that cannot simultaneously meet the requirements of efficient cleaning and not easily scratching glass.

[0005] The present invention provides the following technical solution: a composite fiber wiping cloth, comprising metal fibers and flexible fibers, wherein the metal fibers and the flexible fibers are compositely woven.

[0006] Preferably, the metal fiber is stainless steel fiber.

[0007] Preferably, the flexible fiber is one or a combination of two or more of polyester, nylon, or viscose fiber.

[0008] A method for preparing a composite fiber wiping cloth, characterized by comprising the following steps: 101. Raw material pretreatment: The metal fibers and the flexible fibers are subjected to surface impurity removal treatment to remove impurities from the surfaces of the metal fibers and the flexible fibers; 102. Fiber blending: The metal fibers and the flexible fibers are blended to form a mixed fiber bundle; 103. Weaving: The mixed fiber bundles are introduced into a weaving machine for weaving to form a greige fabric; 104. Cutting and shaping: Cut the fabric.

[0009] Preferably, in step 102, fiber blending, the blending ratio of the metal fiber and the flexible fiber is 1:2 to 1:5.

[0010] Preferably, the diameter of the metal fiber is 0.01-0.1 mm.

[0011] Preferably, the diameter of the flexible fiber is 0.05-0.2 mm.

[0012] Preferably, step 103, weaving, further includes: monitoring the weaving density and the uniformity of the limiting distribution during the weaving process.

[0013] Preferably, the weaving method in step 103, the weaving process, is twill weaving.

[0014] Preferably, in step 103, the knitting process, the parameters of the knitting machine are: transverse needle pitch of 0.3mm-1.0mm, longitudinal tooth pitch of 1.0mm-6.09mm, cylinder speed of 300-700r / min, and licker-in roller speed of 850-1500r / min.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The composite fiber wiping cloth of the present invention comprises metal fibers and flexible fibers, which are woven together. The metal fibers are stainless steel fibers. The flexible fibers are one or more of polyester, nylon, or viscose fibers. The hardness and abrasion resistance of the metal fibers can quickly remove dirt and oil layers after coating from the glass surface. Combined with the mechanical action of a double-sided wiping machine, the cleaning effect is significantly better than that of traditional fiber cloths. The buffering effect of the flexible fibers prevents the metal fibers from directly scratching the glass surface, making it especially suitable for fine wiping of coated glass. The composite weaving of metal fibers and flexible fibers combines the cleaning power of metal fibers with the scratch resistance of flexible fibers.

[0016] 2. The method for preparing the composite fiber wiping cloth of the present invention includes: 101. raw material pretreatment; 102. fiber blending; 103. weaving; 104. cutting and shaping. The composite fiber wiping cloth prepared by the above method can be applied to existing glass wiping equipment without additional equipment modification, which is convenient for industrial promotion.

[0017] 3. In the method for preparing the composite fiber wiping cloth of the present invention, in step 102, the blending ratio of metal fiber and flexible fiber is 1:2 to 1:5. This ratio effectively improves the extensibility and uniformity of the cleaning contact surface of the composite fiber wiping cloth.

[0018] 4. In the method for preparing the composite fiber wiping cloth of the present invention, the diameter of the metal fibers is 0.01-0.1 mm, and the diameter of the flexible fibers is 0.05-0.2 mm. The cleaning and protective performance of the composite fiber wiping cloth is balanced through size matching.

[0019] 5. In the method for preparing the composite fiber wiping cloth of the present invention, step 103, weaving, further includes: monitoring the weaving density and the uniformity of the limiting distribution during the weaving process. This step can effectively ensure the quality of the greige cloth.

[0020] 6. In the method for preparing the composite fiber wiping cloth of the present invention, step 103, the weaving method is twill weave. Twill weave can give the woven composite fiber wiping cloth good softness.

The composite fiber wiping cloth and its preparation method of the present invention have a transverse needle pitch of 0.3mm-1.0mm, a longitudinal tooth pitch of 1.0mm-6.09mm, a cylinder speed of 300-700r / min, and a licker-in roller speed of 850-1500r / min. These parameter settings ensure uniform density, stable structure, and efficient production of the woven cloth, thereby improving the wiping effect and durability of the wiping cloth.

[0030] Furthermore, in this application, the technical features described in an open-ended manner include both closed technical solutions composed of the listed features and open technical solutions that include the listed features.

[0031] To further understand the invention's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings: like Figure 1-2 As shown, the composite fiber wiping cloth includes metal fibers and flexible fibers, woven together. The metal fibers are stainless steel fibers. The flexible fibers are one or more of polyester, nylon, or viscose fibers. It can be understood that the hardness and abrasion resistance of the metal fibers can quickly remove dirt and oil layers from the glass surface after coating. Combined with the mechanical action of a double-sided wiping machine, the cleaning effect is significantly better than traditional fiber cloths. The cushioning effect of the flexible fibers prevents the metal fibers from directly scratching the glass surface, making it especially suitable for fine wiping of coated glass. The composite weaving of metal and flexible fibers combines the cleaning power of the metal fibers with the scratch resistance of the flexible fibers. Of course, it is not limited to this; other materials that can combine high cleaning power and scratch resistance can be used.

[0032] A method for preparing a composite fiber wiping cloth, characterized by comprising the following steps: 101. Raw material pretreatment: The metal fibers and flexible fibers are subjected to surface impurity removal treatment to remove impurities from the surface of the metal fibers and flexible fibers; it can be understood that this step removes impurities from the fibers to facilitate subsequent processing. 102. Fiber blending: Metal fibers and flexible fibers are blended to form mixed fiber bundles; it can be understood that this step uniformly mixes metal fibers and flexible fibers. 103. Weaving: The mixed fiber bundles are introduced into a weaving machine to form a greige fabric; it can be understood that weaving enhances the overall strength. 104. Cutting and Shaping: The greige fabric is cut. This means that the composite woven wiping cloth is used on a wiping machine, and the greige fabric can be cut according to the actual needs of the wiping machine to finally complete the finished product.

[0033] Specifically, in step 102, the fiber blending process, the blending ratio of metal fibers and flexible fibers is 1:2 to 1:5. This ratio effectively improves the extensibility and uniformity of the cleaning contact surface of the composite fiber wiping cloth. Of course, it is not limited to this; any other ratio that can improve the extensibility and uniformity of the cleaning contact surface of the composite fiber wiping cloth is acceptable.

[0034] Specifically, the diameter of the metal fibers is 0.01-0.1 mm, and the diameter of the flexible fibers is 0.05-0.2 mm. This means that the cleaning and protective performance of the composite fiber wiping cloth is balanced through size matching. Of course, it's not limited to this; other materials that can balance the cleaning and protective performance of the composite fiber wiping cloth can be used.

[0035] Specifically, step 103, weaving, also includes monitoring the weaving density and the uniformity of the distribution of the weaving limit during the weaving process. This step effectively ensures the quality of the greige fabric, allowing for timely adjustments during the weaving process. Of course, it's not limited to this; other methods that ensure the quality of the greige fabric can also be used.

[0036] Specifically, in step 103, the weaving method is twill weave. It can be understood that twill weave gives the woven composite fiber wiping cloth good softness. Of course, it's not limited to this; any other weaving method that gives the woven composite fiber wiping cloth good softness is acceptable.

[0037] Specifically, in step 103, during weaving, the parameters of the weaving machine are: transverse stitch pitch of 0.3mm-1.0mm, longitudinal tooth pitch of 1.0mm-6.09mm, cylinder speed of 300-700 r / min, and licker-in speed of 850-1500 r / min. It can be understood that a suitable stitch pitch range can ensure sufficient mechanical strength of the fabric while giving it good flexibility; a larger longitudinal tooth pitch usually results in a thicker fabric with a certain degree of stiffness, which helps maintain its shape on the automatic wiping machine and better cooperate with the wiping head; appropriately increasing the cylinder speed can increase output while ensuring quality; this speed ratio ensures that the fibers can be smoothly and efficiently transferred from the licker-in to the cylinder, preventing fibers from tangling or turning back on the licker-in, thereby ensuring the continuity and stability of the production process and reducing the generation of defective fabric. Of course, it is not limited to this; other parameters that can achieve the same effect can be used. Example 1

[0043] The composite fiber wiping cloth manufactured through this embodiment is used to wipe the surface dirt of coated tempered glass, leaving the coating layer intact and the dirt thoroughly removed. Example 3

[0044] 101. Raw material pretreatment: Surface cleaning treatment is performed on the metal fibers and flexible fibers to remove impurities from their surfaces; the diameter of the metal fibers is 0.1 mm, and the diameter of the flexible fibers is 0.2 mm. The metal fibers are stainless steel fibers, and the flexible fibers are viscose fibers. 102. Fiber blending: Metal fibers and flexible fibers are blended in a ratio of 1:5 to form a mixed fiber bundle; 103. Weaving: The mixed fiber bundles are introduced into the weaving machine for weaving to form the greige fabric; the weaving method is twill weave; the weaving density and the uniformity of the limit distribution are monitored during the weaving process. The parameters of the weaving machine are: transverse needle pitch of 1.0 mm, longitudinal tooth pitch of 6.09 mm, cylinder speed of 700 r / min, and licker-in speed of 1500 r / min.

[0045] 104. Cutting and shaping: Cutting the greige fabric.

[0046] The composite fiber wiping cloth manufactured in this embodiment can be used to wipe large-size glass in batches on a double-sided wiping machine. Its cleaning efficiency is 40% higher than that of traditional cotton cloth, and it does not cause scratches.

[0047] Comparative Example 1: The processing procedures of Comparative Example 1 and Example 1 are basically the same. However, in Comparative Example 1, in step 102, during fiber blending, the weaving ratio of metal fiber and flexible fiber is 2:1.

[0048] Comparative Example 2: The processing procedure of Comparative Example 2 is basically the same as that of Example 1, except that metal fibers are not used in Comparative Example 2. Comparative Example 3: The processing procedure of Comparative Example 3 is basically the same as that of Example 1, except that flexible fibers are not used in Comparative Example 3. Further analysis of the comparative examples revealed several issues. In Comparative Example 1, the excessively high proportion of metal fibers resulted in a stiff, lacking-tough composite fiber wiping cloth that was prone to permanent creases or even breakage during folding or wiping. The overly rigid surface also posed a risk of scratching precision components. In Comparative Example 2, the absence of metal fibers meant the cloth's strength and abrasion resistance were generally lower than that of cloths blended with metal fibers, thus losing the unique scraping and descaling capabilities of metal fibers. In Comparative Example 3, the cloth was entirely composed of metal fibers, making it unable to conform to curved surfaces; the exposed metal fibers easily caused scratches on the wiped surface. The composite fiber wiping cloth manufactured in Example 1 was installed on a double-sided wiping machine to wipe float glass with dust, dirt, and a coating of oil. After wiping, the images were captured using automated optical inspection equipment and compared with a standard parameter database. Image processing identified and marked the locations of glass defects. The results showed a 99% removal rate of dirt and oil. The glass surface showed no scratches, and the yield rate increased from 18% to 58% compared to the glass wiped with the cloth produced in Comparative Example 2. The composite fiber cloth produced in Example 2 was used to wipe the surface dirt of coated tempered glass. After wiping, the acquired images were compared with a standard parameter database using automated optical inspection equipment. Image processing identified and marked the glass defect locations, ensuring the coating layer remained intact and the dirt was thoroughly removed. The composite fiber cloth produced in Example 3 was used to wipe large-size glass in batches on a double-sided wiping machine. After wiping, the acquired images were compared with a standard parameter database using automated optical inspection equipment. Image processing identified and marked the glass defect locations, demonstrating a 40% improvement in cleaning efficiency compared to traditional cotton cloths, with no scratches.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
