Description

Technical Field

[0001] The present invention belongs to the technical field of non-woven wet wipes, and particularly relates to a preparation method of non-woven wet wipes. Background Art

[0002] Wet wipes are a kind of non-woven material with good moisture absorption performance, softness and antibacterial properties. The surface of the wet wipe non-woven fabric is smooth, with a soft touch and is not likely to cause skin sensitivity. It generally consists of two parts: a fabric carrier and a solution impregnated in the fabric carrier. The fabric carrier is made into a disposable cleaning and sanitary product after folding, humidifying and packaging. Due to the characteristics of cleaning, moisturizing and easy to carry, wet wipes have gradually become a commonly used household product.

[0003] At present, most of the raw materials used for the fabric carriers of wet wipes on the market are synthetic fibers such as polyester and polypropylene. Synthetic fibers are widely used textile materials. Wet wipes made of them have advantages such as softness and high cost performance, and can reduce the use of natural fibers to a certain extent; however, their molecular structure is compact, the crystallinity is relatively high, and the surface energy is low, resulting in poor moisture absorption and poor antistatic performance, which are difficult to meet the needs of the sanitary field. Summary of the Invention

[0004] Object of the Invention: The object of the present invention is to solve the deficiencies in the prior art and provide a preparation method of non-woven wet wipes.

[0005] A preparation method of non-woven wet wipes, the specific steps include: S1. Place the non-woven fabric roll on the roller of the fabric rack, start the motor connected to the roller, and drive the roller to rotate by the motor to unwind the non-woven fabric roll. S2.

Mix pure water, preservative and complexing agent, and stir evenly to obtain a first mixed solution; add an inhibitor to the first mixed solution and stir evenly to obtain a second mixed solution. S4. Add a hydrophilic finishing agent to the second mixed solution and stir evenly to obtain an impregnating solution. S5. Pass the non-woven fabric roll through the impregnating tank to fully absorb the impregnating solution. S6. Use an extrusion roller to remove the excess impregnating solution to keep the non-woven fabric moist. S7. Input the length data and width data of the required wet wipes on the cutting machine, and the cutting machine cuts the non-woven fabric roll into the required wet wipe size. S8. Put the cut wet wipes into a packaging bag and seal it with a sealing machine.

[0006] A further improvement of the present invention is that in step S1, the fabric rack is equipped with a deviation rectifying device, and the deviation rectifying device corrects the direction deviation of the non-woven fabric roll during unwinding.

[0007] A further improvement of the present invention lies in that, in step S2, the non-woven fabric roll is subjected to dust removal treatment through a filter bag, and the accumulated charge of the non-woven fabric roll is directly introduced into the ground through a grounding device to maintain the electrostatic balance of the non-woven fabric.

[0008] A further improvement of the present invention lies in that, in step S3, the preservative is phenoxyethanol.

[0009] A further improvement of the present invention lies in that, in step S4, the hydrophilic finishing agent includes silicone compounds and surfactants.

[0010] A further improvement of the present invention lies in that, in step S4, the temperature of the impregnating solution is maintained between 45 and 50 degrees Celsius.

[0011] A further improvement of the present invention lies in that, in step S4, an aqueous solution of sodium hypochlorite is added to the impregnating solution.

[0012] A further improvement of the present invention lies in that the non-woven fabric roll is a spunlace fabric.

[0013] Compared with the prior art, a method for preparing a non-woven wet wipe provided by the present invention at least achieves the following beneficial effects: After hydrophilic post-treatment with a non-woven fabric hydrophilic finishing agent, hydrophilic groups are embedded between polyester fibers through the post-treatment process, changing the surface tension of the non-woven fabric and improving the wettability of the liquid on the surface of the non-woven fabric, thereby achieving the hydrophilicity of the non-woven fabric. The non-woven fabric treated by this method can quickly absorb water and exhibits excellent water absorption performance. Without changing the original properties of the polyester non-woven fabric, it endows the non-woven fabric with excellent wettability and moisture permeability; a conductive layer of insoluble polymer is formed on the surface of the non-woven fabric, which can effectively guide and eliminate the accumulated static charges, reduce the surface resistance of the material, accelerate the dissipation of static charges, and increase the antistatic property. It has the advantages of convenient process, good effect, and being suitable for mass production, meeting the needs of the sanitary field. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. The description of at least one exemplary embodiment below is actually only illustrative and in no way limits the present invention and its application or use.

[0016] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and devices shall be regarded as part of the specification. In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0017] A method for preparing a non-woven wet wipe, the specific steps including: S1. Place the non-woven fabric roll on the roller of the fabric rack, start the motor connected to the roller, and drive the roller to rotate by the motor to unwind the non-woven fabric roll. S2. Perform dust removal treatment and static elimination treatment on the non-woven fabric roll. S3. Mix pure water, a preservative, and a complexing agent, and stir evenly to obtain a first mixed solution; add a corrosion inhibitor to the first mixed solution and stir evenly to obtain a second mixed solution. S4. Add a hydrophilic finishing agent to the second mixed solution and stir evenly to obtain an impregnating solution. S5. Pass the non-woven fabric roll through an impregnation tank to fully absorb the impregnating solution. S6. Use an extrusion roller to remove the excess impregnating solution and keep the non-woven fabric moist. S7. Input the length data and width data of the required wet wipes on a cutting machine, and the cutting machine cuts the non-woven fabric roll into the required wet wipe size. S8. Pack the cut wet wipes into a packaging bag and seal it with a sealing machine.

[0018] A further improvement of the present invention lies in that in step S1, the fabric rack is equipped with a deviation correction device, and the deviation correction device corrects the direction deviation of the non-woven fabric roll during unwinding to ensure that the fabric maintains the correct position during unwinding, thereby reducing manual intervention and improving production efficiency.

[0019] A further improvement of the present invention lies in that in step S2, the non-woven fabric roll is subjected to dust removal treatment through a filter bag. The filter bag adopts a physical filtration principle and can efficiently capture fine particles. The non-woven fabric roll is grounded through a grounding device to directly conduct the accumulated charge into the ground, maintaining the electrostatic balance of the non-woven fabric and reducing equipment failures and safety hazards caused by static electricity.

[0020] A further improvement of the present invention lies in that in step S3, the preservative is phenoxyethanol, and phenoxyethanol can effectively inhibit the growth of microorganisms such as bacteria and molds, can extend the shelf life of the wet wipes, and prevent bacterial growth.

[0021] A further improvement of the present invention lies in that, in step S4, the hydrophilic finishing agent comprises an organosilicon compound and a surfactant. When the organosilicon compound acts as a surfactant, it has various excellent properties. They can not only reduce the surface tension, but also quickly wet and spread on a hydrophobic surface, have super extensibility and pore permeability, and are suitable for various complex surface treatments.

[0022] A further improvement of the present invention lies in that, in step S4, the temperature of the impregnating solution is maintained between 45 and 50 degrees Celsius. Within this temperature range, the dissolution ability and diffusion rate of the solution are optimal.

[0023] A further improvement of the present invention lies in that, in step S4, an aqueous sodium hypochlorite solution is added to the impregnating solution. The aqueous sodium hypochlorite solution has a strong bactericidal ability and can effectively kill bacteria, viruses and fungi to ensure the aseptic state of the impregnating solution.

[0024] A further improvement of the present invention lies in that the non-woven fabric roll is a spunlace fabric. The spunlace fabric interweaves fibers through high-pressure water jets to form a fabric with a tight structure and good air permeability, and has good shaping property and flexibility during the manufacturing process.

[0025] To ensure the cleanliness and safety of the wet wipes, the pure water used in step S3 needs to be filtered and disinfected multiple times. The packaged wet wipes need to be subjected to quality inspection to ensure that each wet wipe meets the production standards. The wet wipes that pass the inspection are successively stored in a dry and cool environment, waiting for subsequent sales and use.

[0026] In summary, a preparation method of a non-woven fabric wet wipe provided by the present invention uses a non-woven fabric hydrophilic finishing agent for hydrophilic post-treatment. Through the post-treatment process, hydrophilic groups are embedded between polyester fibers, changing the surface tension of the non-woven fabric and improving the wettability of the liquid on the surface of the non-woven fabric, thereby realizing the hydrophilicity of the non-woven fabric. The non-woven fabric treated by this method can quickly absorb water and has excellent water absorption performance. Without changing the original properties of the polyester non-woven fabric, it endows the non-woven fabric with excellent wettability and moisture permeability; at the same time, a conductive layer of insoluble polymer is formed on the surface of the non-woven fabric, which can effectively guide and eliminate the accumulated static charges, reduce the surface resistance of the material, accelerate the dissipation of static charges, and increase the antistatic property. It has the advantages of convenient process, good effect and suitability for mass production.

[0027] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
