Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric technology, specifically to a nonwoven fabric with a tear notch. Background Technology

[0002] Non-woven wipes are made of non-woven fabric materials. Composite non-woven fabric is a new type of material that can be called needle-punched cotton. It is made by combining needle-punched cotton with about 10g of PP non-woven fabric. It has the effects of water absorption, heat insulation, and filtration. It can be used for vegetable preservation, filter bags, medical, hygiene industry and automotive industry. Non-woven wipes are used in laboratories to wipe away solutions that have been spilled during experiments. Patent search revealed that publication number: CN206605854U, which discloses a non-woven antibacterial interlayer with good anti-inflammatory and antibacterial properties, good breathability, low skin irritation to infants and young children and low likelihood of allergic reactions.

[0003] When existing nonwoven fabrics are used in laboratories, the fabric is rolled up, making it inconvenient to quickly tear the nonwoven wipes. At the same time, when wiping waste liquids generated in the laboratory, it is unclear whether the waste liquid is a solution with high acid or alkali strength, and blind wiping may be dangerous. In order to solve the above problems, this application proposes a nonwoven fabric with tear notches. Summary of the Invention

[0004] (I) Purpose of the Invention

[0005] To address the technical problems existing in the background art, this invention proposes a non-woven fabric with a tear notch. The tear notch allows for tearing of the grooves on the non-woven fabric wipes, and the through grooves reduce the connection area on both sides of the tear grooves, enabling rapid tearing of the non-woven fabric wipes. The pH test paper changes color upon contact with the solution being wiped, and the color of the pH test paper allows for the measurement of the acidity or alkalinity of the wiping solution, avoiding contact with strong acid or strong alkali solutions during wiping and improving safety when wiping waste liquids.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the present invention provides a non-woven fabric with tear notches, including a non-woven wipe. The non-woven wipe includes an upper non-woven layer and a lower non-woven layer. The upper surface of the upper non-woven layer has several sets of upper tear grooves at equal intervals. The lower surface of the lower non-woven layer has lower tear grooves at positions corresponding to the upper tear grooves. Several sets of through grooves are provided at equal intervals on the upper and lower tear grooves, and the through grooves penetrate the cavity walls of the upper and lower non-woven layers respectively. pH test strips are provided at equal intervals on the lower surface of the non-woven wipe.

[0008] Preferably, the upper tear groove and the lower tear groove extend to the sides of the upper nonwoven fabric layer and the lower nonwoven fabric layer, respectively, and form tear notches at the sides of the upper nonwoven fabric layer and the lower nonwoven fabric layer.

[0009] Preferably, the upper nonwoven fabric layer and the lower nonwoven fabric layer are compositely connected to each other, forming an absorbent layer and a nano-silver ion antibacterial layer.

[0010] Preferably, the surface of the water-absorbing layer and the nano-silver ion antibacterial layer is provided with a pressure groove at a position corresponding to the upper tear groove and the lower tear groove.

[0011] Preferably, the upper surface of the nonwoven fabric layer is rolled with rolling grooves.

[0012] Preferably, the lower surface of the lower nonwoven fabric layer is provided with several sets of limiting grooves at equal intervals, and the limiting grooves are located between two sets of lower tear grooves.

[0013] Preferably, the pH test paper is embedded in the limiting groove.

[0014] The above-mentioned technical solution of this invention has the following beneficial technical effects:

[0015] 1. In this novel design, the upper tear groove, lower tear groove, and pressing groove overlap. The upper and lower tear grooves extend to the sides of the non-woven wipe and form tearing notches on the sidewalls. Several sets of through grooves are equidistantly provided on the surfaces of the upper and lower tear grooves. The tearing notches can tear the tear grooves on the non-woven wipe, and the through grooves can reduce the connection area on both sides of the tear grooves, thus enabling rapid tearing of the non-woven wipe.

[0016] 2. In this new type of wipe, the lower surface of each wiping cloth is embedded with a pH test paper through a limiting groove. The pH test paper changes color after contacting the solution being wiped. The acidity or alkalinity of the solution being wiped can be measured by the color of the pH test paper, avoiding contact with strong acid or strong alkali solutions during wiping, and improving the safety when wiping waste liquid.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this invention.

[0024] like Figure 1-4 As shown, the present invention proposes a nonwoven fabric with tear-notch, comprising a nonwoven wipe 1, the nonwoven wipe 1 comprising an upper nonwoven layer 2 and a lower nonwoven layer 3, the upper surface of the upper nonwoven layer 2 having a plurality of upper tear grooves 6 equidistantly formed, the lower surface of the lower nonwoven layer 3 having a lower tear groove 7 corresponding to the position of the upper tear grooves 6, the upper tear grooves 6 and the lower tear grooves 7 having a plurality of through grooves 8 equidistantly formed, the through grooves 8 respectively penetrating the cavity walls of the upper nonwoven layer 2 and the lower nonwoven layer 3, the two ends of the upper tear grooves 6 and the lower tear grooves 7 respectively extending to the sides of the upper nonwoven layer 2 and the lower nonwoven layer 3, forming tear-notch at the sides of the upper nonwoven layer 2 and the lower nonwoven layer 3, and pH test strips 12 equidistantly formed on the lower surface of the nonwoven wipe 1.

[0025] It should be noted that the non-woven wipe 1 is composed of an upper non-woven fabric layer 2 and a lower non-woven fabric layer 3. The upper tear groove 6, lower tear groove 7 and pressing groove 10 on the upper non-woven fabric layer 2, lower non-woven fabric layer 3, absorbent layer 4 and nano silver ion antibacterial layer 5 overlap together. The upper tear groove 6 and lower tear groove 7 extend to the side of the non-woven wipe 1 and form tear notches on the side walls. Several sets of through grooves 8 are equally spaced on the surface of the upper tear groove 6 and lower tear groove 7. The tear notches can tear the tear grooves on the non-woven wipe 1. The through grooves 8 can reduce the connection area on both sides of the tear groove, so as to realize the quick tearing of the non-woven wipe 1. The double-layer design can increase the thickness of the non-woven wipe 1. In addition, an absorbent layer 4 is compositely connected between the upper non-woven fabric layer 2 and the lower non-woven fabric layer 3. The absorbent layer 4 is composed of a high molecular weight absorbent resin fiber layer, which can improve the water absorption of the non-woven wipe 1 during use.

[0026] like Figure 3 As shown, the upper nonwoven fabric layer 2 and the lower nonwoven fabric layer 3 are compositely connected to the absorbent layer 4 and the nano silver ion antibacterial layer 5.

[0027] It should be noted that the nano silver ion antibacterial layer 5 contains a large number of nano silver ions, which can inhibit the bacteria on the non-woven cloth wipe 1. The non-woven cloth wipe 1 is exposed to the air for a long time, which reduces the growth of bacteria on the non-woven cloth wipe 1.

[0028] like Figure 3 As shown, the surface of the water-absorbing layer 4 and the nano-silver ion antibacterial layer 5 is provided with a pressure groove 10 at the position corresponding to the upper tear groove 6 and the lower tear groove 7.

[0029] It should be noted that the pressure groove 10 allows for easy tearing of the non-woven wipes 1.

[0030] like Figure 1 As shown, the upper surface of the upper nonwoven fabric layer 2 is rolled with rolling grooves 9.

[0031] It should be noted that the upper surface of the nonwoven fabric layer 2 is provided with a rolling groove 9. During the wiping process, the dirt on the table enters into the rolling groove 9, which can reduce the amount of dirt adhering to the surface of the nonwoven cloth wiping cloth 1 and improve the cleaning effect of the nonwoven cloth wiping cloth 1.

[0032] like Figure 4 As shown, several sets of limiting grooves 11 are equidistantly provided on the lower surface of the lower nonwoven fabric layer 3. The limiting grooves 11 are located between two sets of lower tear grooves 7, and the pH test paper 12 is embedded in the limiting grooves 11.

[0033] It should be noted that the lower surface of each torn-off wipe has a pH test strip 12 embedded in it via a limiting groove 11. The pH test strip 12 changes color upon contact with the solution being wiped, allowing for the measurement of the acidity or alkalinity of the solution. This avoids contact with strong acid or alkaline solutions during wiping, thus improving safety when wiping the solution.

[0034] The working principle and usage process of this novel product: The non-woven wipe 1 consists of an upper non-woven layer 2 and a lower non-woven layer 3. The upper tear groove 6, lower tear groove 7, and pressing groove 10 on the upper non-woven layer 2, lower non-woven layer 3, absorbent layer 4, and nano-silver ion antibacterial layer 5 overlap. The upper tear groove 6 and lower tear groove 7 extend to the sides of the non-woven wipe 1, forming tearing notches on the sidewalls. Several sets of through grooves 8 are equidistantly arranged on the surfaces of the upper tear groove 6 and lower tear groove 7. The tearing notches allow tearing of the tear grooves on the non-woven wipe 1. The through grooves 8 reduce the connecting area on both sides of the tear grooves, enabling rapid tearing of the non-woven wipe 1. The double-layer design increases the thickness of the non-woven wipe 1. Furthermore, an absorbent layer 4 is compositely connected between the upper non-woven layer 2 and the lower non-woven layer 3. The absorbent layer 4 is composed of a high-molecular-weight absorbent resin fiber layer. To improve the absorbency of the non-woven wipes 1 during use, pH test strips 12 are embedded in the lower surface of each torn wipe through the limiting groove 11. The pH test strips 12 change color upon contact with the solution being wiped, allowing for the measurement of the acidity or alkalinity of the solution. This avoids contact with strong acid or alkali solutions during wiping, improving safety. The upper surface of the non-woven fabric layer 2 has rolled grooves 9. During wiping, dirt on the table enters the rolled grooves 9, reducing the amount of dirt adhering to the surface of the non-woven wipes 1 and improving the cleaning effect. The nano silver ion antibacterial layer 5 contains a large number of nano silver ions, which can inhibit the growth of bacteria on the non-woven wipes 1 when exposed to air for a long time.

[0035] It should be understood that the above-described specific embodiments of this invention are merely illustrative or explanatory of the principles of this invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this invention should be included within the protection scope of this invention. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
