Description

[0001] This utility model is a divisional application of the original application. The filing date of the original application is October 20th, 2023, the application number is 2023228160932, and the invention title is: A skin-friendly and moisturizing non-woven fabric mask base fabric and its production equipment. Technical Field

[0002] This utility model relates to the technical field of non-woven fabrics, and in particular to a skin-friendly and moisturizing non-woven fabric mask base fabric. Background Art

[0003] Masks have become essential skin care products for many beauty lovers because they have various effects such as moisturizing, whitening, and freckle removal. Masks can be divided into carrier masks and non-carrier masks according to the usage method. Currently, the most popular masks on the market are carrier masks, which are composed of a mask base fabric and essence liquid. The mask base fabric mainly uses non-woven fabric as the carrier because non-woven fabric mask base fabrics have advantages such as good quality and low price, high porosity, softness, and moisture retention.

[0004] Currently, most non-woven fabric mask base fabrics on the market are prepared by hydroentangling viscose fibers. Their base fabrics are soft, have a good touch, stable performance, and no irritation. However, viscose fibers are relatively expensive, have poor strength compared with spunbond non-woven fabrics, average air permeability, and can carry less essence liquid. In view of the above defects, we have invented a spunbond non-woven fabric mask base fabric with long filaments and short fibers bonded to each other, which can better make up for the defects of traditional non-woven fabrics and can meet the high requirements for the air permeability and moisture retention performance of the base fabric at the same time. The publication number is CN212611248U, which discloses a high-pressure hydroentangling device for producing mask base fabrics, including a second guide roller, a device body, a base, and a winding roller. One side of the top of the base is fixedly installed with a device body. The outside of the device body is fixedly installed with a control panel through screws, and a single-chip microcomputer is embedded in the control panel. One side of the outside of the device body is hinged with a protective door through a hinge. One side of the top of the base is fixedly installed with a second support column, and the other end of the top of the base is fixedly installed with a power box. A motor is fixedly installed in the power box through screws. A rotating shaft is hinged between the second support column and the power box. In this utility model, by connecting the connecting pipe to a high-pressure water pump, water is sprayed out from the hydroentangling head through the pressure of the water pump. The water will be sprayed onto the non-woven fabric body on the support roller after passing through high pressure, and the water will penetrate through the non-woven fabric body to achieve the purpose of piercing, thereby achieving the purpose of providing the tensile force of the non-woven fabric. This device uses the hydroentangling method to produce mask base fabrics, resulting in generally low strength of the obtained base fabrics. Content of the Utility Model

[0006] To achieve the above object, the solution provided by the present utility model is: a skin-friendly and moisturizing non-woven fabric mask base fabric, comprising a first fiber layer, a fiber entanglement layer, and a second fiber layer sequentially arranged from bottom to top.

[0007] Further, the first fiber layer is one of polyethylene / polypropylene core-sheath type bicomponent staple fibers.

[0008] Further, the fiber entanglement layer is formed by entangling polyethylene / polypropylene core-sheath type bicomponent staple fibers with spunbonded polypropylene filaments.

[0009] Further, the second fiber layer is one of polyethylene / polypropylene core-sheath type bicomponent staple fibers.

[0010] The beneficial effects of the present utility model are: by setting a three-layer structure, wherein the first fiber layer is one of polyethylene / polypropylene core-sheath type bicomponent staple fibers, the fiber entanglement layer is formed by entangling polyethylene / polypropylene core-sheath type bicomponent staple fibers with spunbonded polypropylene filaments, and the second fiber layer is one of polyethylene / polypropylene core-sheath type bicomponent staple fibers.

[0030] In this embodiment, the specific production process of the skin-friendly and moisturizing non-woven fabric mask base cloth is as follows:

[0031] S1. Start the screw extruder 11. The screw extruder 11 extrudes molten polypropylene fibers, which are then successively passed through the filter 13 and the metering pump 14 and conveyed to the spinning box 15. In cooperation with the cold air blower 16 and the monomer extraction device 17, spunbond polypropylene filaments are conveyed to the stretching channel 19, and under the action of the high-speed air flow of the cold air blower 16, the spunbond polypropylene filaments are stretched and conveyed in the stretching channel 19.

[0032] S2. Start the two fiber opening machines 31 respectively. The fiber opening machines 31 open up the polyethylene or polypropylene raw materials and then convey them to the carding machine 33 for carding to be neat, so as to form polyethylene / polypropylene core-sheath type bicomponent staple fibers, which are then input into the stretching channel 19 through the air supply opening 34, so that the spunbond polypropylene filaments and the polyethylene / polypropylene core-sheath type bicomponent staple fibers form a fiber entanglement layer b, which plays a supporting role.

[0033] S3. After the fiber entanglement layer b is formed, the two air supply openings 34 continue to convey the polyethylene / polypropylene core-sheath type bicomponent staple fibers, and the polyethylene / polypropylene core-sheath type bicomponent staple fibers are consolidated by hot air on the two surfaces of the fiber entanglement layer b respectively to form the first fiber layer a and the second fiber layer c respectively, and then continue to fall onto the forming machine 2 to form the non-woven fabric mask base fabric of this embodiment. The base fabric has a three-layer structure; wherein, the atomizer 161 atomizes the hydrophilic oil agent and evenly sprays it onto the first fiber layer a, the fiber entanglement layer b and the second fiber layer c through the cold air blower 16.

[0034] S4. After the skin-friendly and moisturizing non-woven fabric mask base fabric is formed and continues to be conveyed, when the non-woven fabric mask base fabric is conveyed to the liquid application mechanism, the liquid guide pipe 45 conveys the hydrophilic solvent in the upper liquid pool 41 to the nozzle 44, and the nozzle 44 sprays the hydrophilic solvent onto the upper liquid guide roller 43 located on the upper side. Since the lower liquid guide roller 43 is partially immersed in the upper liquid pool 41, the two liquid guide rollers 43 evenly apply the hydrophilic solvent to the two upper liquid rollers 42 respectively through the rolling direction, so that the two upper liquid rollers 42 evenly apply the hydrophilic solvent to the upper and lower surfaces of the non-woven fabric mask base fabric, making the hydrophobic non-woven fabric mask base fabric form a skin-friendly and moisturizing non-woven fabric mask base fabric.

[0035] S5. The skin-friendly and moisturizing non-woven fabric mask base fabric continues to be conveyed into the oven 5 for drying, so that the porosity of the obtained mask base fabric is greatly increased and the air permeability is excellent. Since the increase in porosity can hold more essence liquid, the moisturizing performance is more excellent.

[0036] After drying, continue the conveyance, and then rotate the two adjusting screws 66 correspondingly according to actual requirements to drive the two sliding seats 65 to move, so that the two sliding seats 65 approach or move away from each other until they move to the set positions, realizing the adjustment of the positions of the two cutting knives 64. In this way, when the skin-friendly and moisturizing non-woven fabric mask base fabric passes through the fabric guide roller 62, the excess base fabric is cut off by the two cutting knives 64, and finally wound by the winding roller 63.

[0037] The above-described embodiments are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any person skilled in the art can make more possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention. Therefore, all equivalent changes made according to the idea of the present invention without departing from the content of the technical solution of the present invention shall be covered by the protection scope of the present invention.
