[0051] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0052] Example 1
[0053] Please refer to Figure 1 As shown, an embodiment of the present invention provides a method for preparing a makeup-removable cleansing beauty cotton towel, comprising the following steps:
[0054] S1. Selection of raw materials:
[0055] We select natural cotton as the raw material for cotton wipes to ensure that the cotton is of high quality, with a fiber length of no less than 25 mm and an impurity content of no more than 0.5%.
[0056] The raw materials can be produced using a pure cotton spunlace non-woven fabric process, in which the fiber arrangement density of the cotton is controlled to be no less than 80 fibers per square centimeter to ensure that the cotton wipes are soft and delicate, have good water absorption, and do not shed.
[0057] S2. Processing of raw materials:
[0058] The cotton in S1 is deeply cleaned in a cleaning machine for no less than 30 minutes to remove dust and impurities in the raw materials.
[0059] The cleaned cotton is laid crosswise at a 45-degree angle through a web laying machine to form a uniformly distributed cotton web. The specifications of the cotton web range from 60 to 160 g / m 2 , preferably 100g / m 2 , for optimal softness and durability.
[0060] S3, Spunlace process:
[0061] The cotton web in S2 is spunlaced on both sides by a high-pressure spunlacing device, and the spunlacing pressure is controlled between 20 and 40 bar to enhance the strength and stability of the cotton web. The spunlacing times are not less than 3 times to ensure that the fibers inside the cotton web are tightly combined to obtain a semi-finished cosmetic cotton product.
[0062] S4, slitting and forming:
[0063] The semi-finished cotton pads obtained in S3 are cut into final cotton towel products through precision slitting equipment. The slitting width is controlled between 15 and 30 cm, and the length can be freely adjusted according to needs.
[0064] Use an automatic folding machine to control the speed and positioning of the fabric conveying system, accurately control the folding angle and number of layers, and fold the spunlace nonwoven fabric into the required specifications, such as three-layer folding or four-layer folding.
[0065] S5. Packaging and sterilization:
[0066] The finished cotton wipes in S4 are sterilized by high-pressure steam, with the sterilization temperature controlled at 121°C for no less than 15 minutes to ensure the hygiene and safety of the product.
[0067] Finally, the cotton wipes are packaged using paper boxes, plastic boxes or pillow-type packaging. During the packaging process, a proper amount of desiccant is added to keep the product dry, thereby obtaining cotton wipes with facial cleansing and beauty functions.
[0068] By adopting the above technical solution, not only can a soft, absorbent and makeup-removing cotton towel be prepared, but also the cotton towel has a good skin care effect and can effectively replace traditional cosmetic cotton and other face-washing towel products. At the same time, when cutting and folding the cotton towel, various parameters can be accurately controlled, which facilitates the free adjustment of the spacing and number of the cutters, thereby greatly increasing the practicality and flexibility of the present invention.

[0077] Please refer to Figures 2 to 12 As shown, the slitting structure 3045 includes a connecting seat 30451, which is installed on the bottom of the rotating sleeve 3043 by means of mounting bolts 30452. A slitting knife 30453 for cutting cotton towels is rotatably installed on the bottom of the connecting seat 30451. By loosening the mounting bolts 30452, the slitting knife 30453 can be easily disassembled and assembled, thereby facilitating the maintenance or replacement of the slitting knife 30453.
[0078] The working principle of the present invention is: not only can a soft, absorbent and makeup-removing cleansing cotton towel be prepared, but also the cotton towel has a good skin care effect and can effectively replace traditional cosmetic cotton and other face-washing towel products. Moreover, when the cotton towel is cut, the T-shaped block 30423 is pulled by operating the slide bar 30422, and the T-shaped block 30423 is disengaged from the corresponding first slot 30425, so that the adjusting sleeve 3041 can be slidably adjusted on the mounting shaft 303, thereby realizing the slitting of the slitting knife 304 53, and at the same time, by pulling the sliding pin 30442 and making the sliding pin 30442 disengage from the second slot 30444, the rotating sleeve 3043 can be rotated, so that the slitting knife 30453 can be rotated upward, so that the number of slitting knives 30453 can be increased or decreased as needed, and at the same time, by loosening the mounting bolt 30452, the slitting knife 30453 can be easily disassembled and assembled, and the slitting knife 30453 can be easily maintained or replaced, thereby greatly increasing the practicality of the present invention.
