Description

[Technical Field]

[0001] The present invention belongs to the technical field of anti-slip fabrics, and particularly relates to a type of anti-slip fabric and a manufacturing method thereof. [Background technology]

[0002] Conventional anti-slip treatments for knitted fabrics include plastic anti-slip dots, silicone anti-slip dots, and PVC anti-slip dots. These types of anti-slip fabrics have anti-slip dots attached to the base fabric with adhesive, but the anti-slip dots are prone to peeling and lack abrasion resistance. In addition, the adhesives generally contain volatile gases, which emit a strong chemical odor and can be very harmful to the human body.

[0003] Chinese Patent Application No. CN201310318632.8 discloses a type of non-slip knitted fabric and its manufacturing method. This non-slip knitted fabric comprises a base polyolefin knitted fabric layer and a non-slip layer directly laminated to the surface of the base polyolefin knitted fabric layer. The weight ratio of each component of the non-slip layer is as follows: Polyethylene or polypropylene 50% to 85% Ethylene-vinyl acetate copolymer 10% to 30% · Polyolefin elastomer 5% to 30%.

[0004] The conventional anti-slip knitted fabrics mentioned above achieve anti-slip treatment by directly compounding an anti-slip layer onto a base fabric, and use dotted plastic anti-slip layers. However, with this type of conventional anti-slip fabric, the anti-slip layer does not effectively bond with the surface of the napped material during manufacturing and use, which can lead to the anti-slip layer peeling off or color transfer over time. As a result, the ideal anti-slip effect is not achieved. Furthermore, when dotted plastic anti-slip layers are used, the anti-slip layer is sticky, making it prone to dust adhesion over time. When dust adheres to the anti-slip layer, the anti-slip effect is significantly reduced, reducing friction and making it more susceptible to movement, which seriously affects its usefulness. Summary of the Invention [Problem to be solved by the invention]

[0005] The main technical problem to be solved by this invention is to provide a kind of anti-slip fabric and its manufacturing method. The invention has a simple overall structure, an environmentally friendly and simple production process, no color transfer, and excellent anti-slip effect. It is mainly intended for use on the surface and back of various anti-slip products. [Means for solving the problem]

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: This is an anti-slip fabric, which includes a base layer (1). A raised layer (2) is knitted on one or both sides of the base layer (1), and an anti-slip material is sprayed evenly onto the raised layer (2). The amount of the anti-slip material used is 5 to 150 g / m 2 After hardening, the anti-slip material is fixed to the raised layer (2) to form solidified anti-slip particles (3).

[0007] The following is a further optimization content of the above technical solution according to the present invention. 1. The raised layer (2) is composed of a plurality of randomly arranged naps (21), and the extended length of the naps (21) is 0.1 to 5 mm. 2. The anti-slip material is sprayed onto the nap layer (2) of the base fabric (1) using a paste sprayer. The anti-slip material is sprayed from the sprayer in the form of mist-like liquid particles, which fall evenly onto the nap layer (2). The mist-like liquid particles are then dried and hardened in a temperature environment of 100-190°C, and are fixed to the nap (21) of the nap layer (2) to form solidified anti-slip particles (3). 3. The solidified anti-slip particles (3) wrap around the corresponding raised naps (21), and the solidified anti-slip particles (3) move slightly together with the raised naps (21). 4. For the base layer fabric (1), nonwoven felt, raised fabric, PP nonwoven fabric, polyester raised fabric, and various types of fabric with hair are used. 5. The anti-slip material is composed of the following weight ratios: DOTP / DOP (plasticizer): 30-70% PVC: 10-40% SiO2: 5-20% 6. The particle size of the solidified anti-slip particles (3) is 20 to 300 μm.

Then, the base fabric (1) prepared in step S1 is spread and flattened, and the napped layer (2) is placed facing upward. The paste sprayer is operated, and the paste-like anti-slip material is sprayed evenly onto the napped layer (2). At this time, the anti-slip material sprayed from the sprayer is in the form of mist-like liquid particles, which fall evenly onto the napped layer (2). At this time, the mist-like liquid particles adhere to the nap (21) of the napped layer (2). The spray pressure of the sprayer is 0.15 to 0.4 MPa, and the amount of anti-slip material sprayed is 5 to 150 g / m. 2 is. Step S4.

[0010] [Figure 1]1 is a schematic diagram of the overall structure in an embodiment of the present invention. [Figure 2] 1 is a diagram showing an actual example of the anti-slip fabric according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0011] The present invention will be described in more detail below with reference to the drawings and examples. [Example]

[0012] As shown in Figures 1 and 2, the anti-slip fabric of the present invention comprises a base layer fabric (1). A raised layer (2) is knitted onto at least one surface of the base fabric (1). The brushed layer (2) is sprayed with an anti-slip material evenly. The amount of anti-slip material used is 5 g / m 2 After hardening, the anti-slip material is fixed to the raised layer (2) to form solidified anti-slip particles (3). The base layer fabric (1) uses nonwoven felt.

[0013] The upper surface of the base fabric (1) is subjected to a nap-raising process to form a napped layer (2). The napped layer (2) is composed of a plurality of randomly arranged naps (21). The extended length of the naps (21) is 1 mm.

[0014] The anti-slip material is composed of the following weight ratios: DOTP / DOP (plasticizer): 65% PVC: 25% SiO2: 10%

[0015] The anti-slip material is sprayed onto the nap layer (2) of the base fabric (1) using a paste sprayer. The anti-slip material is sprayed from the sprayer in the form of mist-like liquid particles, which fall evenly onto the nap layer (2). The mist-like liquid particles are then dried and hardened in a temperature environment of 150°C, and are fixed to the nap (21) of the nap layer (2) to form solidified anti-slip particles (3).

[0016] The solidified anti-slip particles (3) are fixed to the naps (21) of the brushed layer (2), so that the solidified anti-slip particles (3) envelop the corresponding naps (21). After drying and curing, the solidified anti-slip particles (3) are firmly fixed to the naps (21), improving the fixing effect and preventing the solidified anti-slip particles (3) from peeling off from the brushed layer (2). Furthermore, after the solidified anti-slip particles (3) are fixed to the naps (21), the naps (21) are randomly arranged, so the solidified anti-slip particles (3) do not come into direct contact with the base fabric (1) and move slightly along with the naps (21). Furthermore, when one side of the brushed layer (2) comes into contact with other materials, the presence of the solidified anti-slip particles (3) allows this anti-slip fabric to exhibit excellent anti-slip properties.

[0017] Prior art uses dotted plastic or silicone anti-slip materials. In other words, anti-slip rubber dots or lines are applied to anti-slip fabrics using a dotted or lined method. These dots or lines are fixed in position and prone to dust adhesion, which negatively impacts the anti-slip effect. Unlike prior art, the present invention uses a spray-applied anti-slip material with solidified anti-slip particles (3). After drying and curing, the solidified anti-slip particles (3) are firmly fixed to the nap (21). This allows the solidified anti-slip particles (3) to move slightly along with the nap (21), improving their adaptability when in contact with other materials and improving the anti-slip effect. The particle size of the solidified anti-slip particles (3) is 60 μm.

[0018] In this Example 1, a manufacturing method for anti-slip fabric is provided, which is carried out according to the following steps.

[0019] Step S1. Preparation of raw materials A nonwoven felt is used for the base fabric (1), and the upper surface of the base fabric (1) is subjected to a nap-raising process to form a nap layer (2). The length of the nap (21) of the nap layer (2) is 1 mm.

[0020] Step S2. Preparation of anti-slip material Measure the ingredients in the following order according to weight ratio: DOTP / DOP (plasticizer): 65% PVC: 25% SiO2: 10% These are put into a mixer and mixed to obtain a paste-like anti-slip material.

[0021] Step S3. Spray application The paste-like anti-slip material is put into a paste sprayer, and the base fabric (1) prepared in step S1 is spread and flattened, with the nap layer (2) facing upward. Then, the paste sprayer is operated, and the paste-like anti-slip material is sprayed evenly onto the nap layer (2). At this time, the anti-slip material sprayed from the sprayer is in the form of mist-like liquid particles, which fall evenly onto the nap layer (2). At this time, the mist-like liquid particles adhere to the nap (21) of the nap layer (2). In step S3, the spray pressure of the paste sprayer is set to 0.2 MPa, and the amount of spray material used is 5 g / m 2 is.

[0022] Step S4. Drying and curing In step S3, the base material (1) sprayed with the anti-slip material is steadily transported into a high-temperature drying chamber, where the atomized liquid particles are dried and hardened in a temperature environment of 150°C. The drying time is 3 minutes.

[0023] Step S5. After drying is complete, the material is cooled to room temperature by air cooling. After cooling, the atomized liquid particles are fixed to the nap (21) of the napped layer (2) to form solidified anti-slip particles (3). This completes the anti-slip fabric, which is then wound up, cut, and packaged. [Example]

[0024] As shown in FIG. 1, the anti-slip fabric of the present invention comprises a base layer fabric (1). The base fabric (1) is made of a raised fabric, and raised layers (2) are knitted on both the upper and lower surfaces of the base fabric (1).

[0025] The raised layer (2) is composed of a plurality of randomly arranged naps (21). The length of the naps (21) is 1.5 mm. The raised layer (2) is uniformly coated with an anti-slip material by spraying, and the amount of the anti-slip material used is 100 g / m. 2 After hardening, the anti-slip material is fixed to the raised layer (2) to form solidified anti-slip particles (3).

[0026] The anti-slip material is composed of the following weight ratios: DOTP / DOP (plasticizer): 60% PVC: 25% SiO2: 15%

[0027] The anti-slip material is sprayed onto the nap layer (2) of the base fabric (1) using a paste sprayer. The anti-slip material sprayed from the sprayer is a mist of liquid particles that falls evenly onto the nap layer (2). The mist of liquid particles is then dried and hardened in a temperature environment of 150°C, and is fixed to the nap (21) of the nap layer (2) to form solidified anti-slip particles (3). The particle size of the solidified anti-slip particles (3) is 90 μm.

[0028] In this Example 2, a method for manufacturing the anti-slip fabric is further provided, which is carried out according to the following steps.

[0029] Step S1. Preparation of raw materials A raised fabric is used for the base fabric (1), and the upper and lower surfaces of the base fabric (1) are raised to form a raised layer (2). The length of the raised nap (21) of the raised layer (2) is 1.5 mm.

[0030] Step S2. Preparation of anti-slip material Measure the ingredients in the following order according to weight ratio: DOTP / DOP (plasticizer): 60% PVC: 25% SiO2: 15% These are put into a mixer and mixed to obtain a paste-like anti-slip material.

[0031] Step S3. Spray application The paste-like anti-slip material is loaded into a paste sprayer, and the base fabric (1) prepared in step S1 is spread and flattened, with the nap layer (2) of the anti-slip material to be sprayed facing upward. The paste sprayer is then activated, and the paste-like anti-slip material is sprayed evenly onto the nap layer (2). The spray pressure of the sprayer is set to 0.2 MPa, and the amount of spray material used is 60 g / m2. At this time, the anti-slip material sprayed from the sprayer is in the form of mist-like liquid particles, which fall evenly onto the nap layer (2). At this time, the mist-like liquid particles adhere to the nap (21) of the nap layer (2).

[0032] Step S4. Drying and curing In step S3, the base material (1) sprayed with the anti-slip material is sent into a high-temperature drying chamber, where the atomized liquid particles are dried and hardened in a temperature environment of 130°C. The drying time is 2 minutes.

[0033] Step S5. After drying is complete, the fabric is cooled to room temperature by air cooling. After cooling, the mist liquid particles are fixed to the nap (21) of the nap layer (2) to form solidified anti-slip particles (3), completing the initial anti-slip fabric.

[0034] Step S6. This basic anti-slip fabric is then turned over and placed on the other side with the napped layer (2) facing upward. Steps S3 to S5 are then repeated to spray the anti-slip material onto the napped layer (2) on the other side, and after solidification, the solidified anti-slip particles (3) are fixed to the napped layer (2) on this side as well. This completes the anti-slip fabric with solidified anti-slip particles (3) attached to both sides. Finally, the anti-slip fabric is rolled up, cut, and packaged. [Example]

[0035] As shown in FIG. 1, the anti-slip fabric of the present invention comprises a base layer fabric (1). The base fabric (1) is made of either nonwoven felt or raised fabric, and a raised layer (2) is uniformly knitted onto one surface of the base fabric (1).

[0036] The raised layer (2) is composed of a plurality of randomly arranged naps (21). The length of the naps (21) is 5 mm. The raised layer (2) is uniformly sprayed with an anti-slip material, and the amount of the anti-slip material used is 90 g / m. 2 After hardening, the anti-slip material is fixed to the raised layer (2) to form solidified anti-slip particles (3).

[0037] The anti-slip material is composed of the following weight ratios: DOTP / DOP (plasticizer): 55% PVC: 30% SiO2: 15%

[0038] The anti-slip material is sprayed onto the nap layer (2) of the base fabric (1) using a paste sprayer. The anti-slip material sprayed from the sprayer is in the form of mist-like liquid particles, which fall evenly onto the nap layer (2). The mist-like liquid particles are then dried and hardened in a temperature environment of 190°C, and are fixed to the nap (21) of the nap layer (2), forming solidified anti-slip particles (3). The particle size of the solidified anti-slip particles (3) is 150 μm.

[0039] In this Example 3, a method for manufacturing the anti-slip fabric is further provided, which is carried out according to the following steps:

[0040] Step S1. Preparation of raw materials The upper and lower surfaces of the base fabric (1) are subjected to a nap raising process to form a napped layer (2). The length of the napped layer (21) is 5 mm.

[0041] Step S2. Preparation of anti-slip material Measure the ingredients in the following order according to weight ratio: DOTP / DOP (plasticizer): 55% PVC: 30% SiO2: 15% These are put into a mixer and mixed to obtain a paste-like anti-slip material.

[0042] Step S3. Spray application The paste-type anti-slip material is put into a paste sprayer, the base fabric (1) prepared in step S1 is spread and flattened, and the raised layer (2) is placed facing upward. Then, the paste sprayer is operated to spray the paste-type anti-slip material evenly onto the raised layer (2). The spray pressure of the sprayer is set to 0.2 MPa, and the amount of spray material used is 90 g / m. 2 At this time, the anti-slip material sprayed from the sprayer is in the form of mist-like liquid particles that fall evenly onto the raised layer (2). At this time, the mist-like liquid particles adhere to the naps (21) of the raised layer (2).

[0043] Step S4. Drying and curing In step S3, the base material (1) sprayed with the anti-slip material is sent into a high-temperature drying chamber, where the atomized liquid particles are dried and hardened in a temperature environment of 190°C. The drying time is 4 minutes.

[0044] Step S5. After drying is complete, the material is cooled to room temperature by air cooling. After cooling, the mist liquid particles are fixed to the nap (21) of the nap layer (2) to form solidified anti-slip particles (3). This completes the anti-slip fabric, which is then wound up, cut, and packaged.

[0045] The anti-slip fabrics produced in Examples 1 to 3 above can be used for the upper surface and backing materials of carpets, pillowcase materials, quilted pads, mattresses, various composite pads, trapezoidal carpets, sloped carpets, and various other surface and backing materials that require anti-slip properties.

[0046] The non-slip fabric manufactured by the present invention has a raised nap (21) on its raised layer (2), which provides the fabric with a certain level of anti-slip performance. Furthermore, an anti-slip material is sprayed onto the raised layer (2), which transforms into mist-like liquid particles during the spraying process and evenly distributes them onto the raised layer (2). The mist-like liquid particles are then dried and hardened in a temperature environment of 100-190°C, where they are fixed to the raised nap (21) of the raised layer (2) to form solidified non-slip particles (3). These solidified non-slip particles (3) improve the anti-slip performance, and the non-slip fabric has excellent abrasion resistance, anti-slip properties, and durability. Furthermore, this fabric retains the original aesthetic appearance of the woven fabric, has a simple and easy-to-implement manufacturing process, is recyclable, and does not cause environmental pollution.
