Description

Technical Field

[0001] The invention belongs to the technical field of facial mask cloths, and in particular relates to a non-irritating, lifting and firming facial mask cloth and a preparation method and application thereof. Background Art

[0002] Facial mask cloth is a carrier of facial mask essence and can be applied directly to the face. Currently, the most common type of facial mask cloth on the market is non-woven fabric, but its air permeability and elasticity are poor, resulting in poor use effect and comfort. As a result, more and more manufacturers choose elastic fiber to prepare facial mask cloth. The mask cloth produced by elastic fiber can achieve good elasticity after heat shrinkage treatment, which will bring consumers an excellent use experience.

[0003] CN108866813A discloses a method for preparing an elastic water-retaining and moisture-absorbing facial mask cloth, which belongs to the technical field of facial mask cloth preparation. The invention blends activated carbon with polyester to obtain highly elastic and hydrophilic polyester fibers. The crystallinity of viscose fibers prepared using cheap rice bran as raw materials is much lower than that of traditional facial mask cloth raw materials such as cotton and linen. The activated carbon used in the invention is fired at high temperature and without oxygen on bamboo pieces. Since bamboo is acidic, the prepared activated carbon is also acidic. Under acidic conditions, bacterial growth and reproduction will be inhibited, which plays an antibacterial role. The polyester fiber itself has excellent elasticity. After being compounded with the viscose fiber, the gaps between the polyester fibers can be filled, so that the elasticity of the facial mask cloth is enhanced.

[0004] CN109680411A discloses a method for manufacturing a multi-component ultra-fine mask cloth, which forms capillary cavities of different sizes between continuous filament multi-component ultra-fine fibers, so that more capillary gaps are generated on the cloth surface, making the cloth surface fuller, and the amount of liquid carried is greatly increased, which can fully increase the absorption of essence liquid, thereby achieving high elasticity and ultra-flexibility of the ultra-fine mask cloth. At the same time, when the fibers are fully cracked, the fibers are subjected to secondary water softening treatment, making the cloth surface more delicate and good in skin adhesion. At the same time, due to the introduction of PLA, the ultra-fine fiber mask cloth is degradable and more environmentally friendly.

[0005] However, if the mask cloth obtained by the above technology is used as a water-based mask or a freeze-dried mask, the mask cloth directly contacts the skin. Although it has a certain degree of fineness and elasticity, it is highly irritating and will bring a bad user experience to consumers. Therefore, it is very necessary to provide a non-irritating, highly elastic mask cloth, which has a huge market demand and will bring considerable economic benefits. Summary of the invention

[0006] In view of the deficiencies in the prior art, the object of the present invention is to provide a non-irritating, lifting and firming facial mask cloth and a preparation method and application thereof.

[0007] In order to achieve the purpose of the invention, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a non-irritating, lifting, and firming facial mask cloth, the facial mask cloth comprising a cellulose fiber surface layer, an elastic middle layer, and a cellulose fiber bottom layer stacked in sequence;

[0009] The materials of the cellulose fiber surface layer and the cellulose fiber bottom layer are both fine-denier viscose fibers, with a fineness of 0.5dtex-1.0dtex (for example, 0.6dtex, 0.7dtex, 0.8dtex, 0.9dtex or 1dtex, etc.) and a length of 38-52mm (for example, 40mm, 42mm, 44mm, 46mm, 48mm or 50mm, etc.);

[0010] The material of the elastic middle layer is PU fiber.

[0011] The present invention adopts PU fiber as the elastic middle layer and cellulose fiber layers on both sides, wherein the middle layer has good elasticity. After being made into a membrane cloth, it can provide good elasticity. The cellulose fiber layer can make the fiber very soft by controlling the fineness. The surface of the prepared membrane cloth is very delicate and soft, and can provide a good skin feel. Since the cellulose fiber layer is in contact with the skin, the final facial mask cloth is very friendly to the skin, has no irritation, and is safer and gentler.

[0012] Preferably, the fine denier viscose fiber includes any one of lyocell fiber, viscose fiber or cuprammonium fiber, or a combination of at least two thereof.

[0013] Preferably, the fineness of the PU fiber is at the micron level.

[0014] Preferably, the longitudinally distributed fiber proportions in the cellulose fiber surface layer and the cellulose fiber bottom layer are independently 60%-80% (for example, 62%, 64%, 66%, 68%, 70%, 72%, 74%, 76% or 78%, etc.), and the transversely distributed fiber proportions are independently 20%-40% (for example, 22%, 24%, 26%, 28%, 30%, 32%, 34%, 36% or 38%, etc.).

[0015] In the present invention, the ductility of the cellulose fiber layer can be improved by setting the distribution ratio of the transverse and longitudinal fibers in the cellulose fiber surface layer or the bottom layer.

[0016] Preferably, the gram weight of the cellulose fiber surface layer and the cellulose fiber bottom layer is independently 10-20 g / m 2 , for example, it can be 11g / m 2 , 13g / m 2 , 15g / m 2, 17g / m 2 or 19g / m 2 wait.

[0017] Preferably, the elastic middle layer has a grammage of 8-15 g / m 2 , for example 8g / m 2 , 9g / m 2 , 10g / m 2 , 11g / m 2 , 12g / m 2 , 13g / m 2 or 14g / m 2 wait.

[0018] Other specific point values ​​within the above numerical ranges can be selected and will not be described in detail here.

[0019] In a second aspect, the present invention provides a method for preparing the non-irritating, lifting, and firming facial mask cloth as described in the first aspect, the preparation method comprising:

[0020] (1) Using fine denier viscose fiber as raw material, preparing a cellulose fiber surface layer and a cellulose fiber bottom layer by carding and spunlace process;

[0021] The elastic middle layer is perforated;

[0022] (2) The upper and lower surfaces of the elastic middle layer are respectively compounded with the cellulose fiber surface layer and the cellulose fiber bottom layer using an adhesive to obtain the non-irritating, lifting and firming facial mask cloth.

[0023] Preferably, the spunlace process in step (1) is performed through six spunlace steps.

[0024] Preferably, the pressures of the first and second hydroentanglement steps are independently 0.5-1.5 MPa, for example, 0.6 MPa, 0.8 MPa, 1 MPa, 1.2 MPa or 1.4 MPa.

[0025] Preferably, the pressure of the third to sixth hydroentanglement steps is 2-3 MPa, for example, 2.1 MPa, 2.3 MPa, 2.5 MPa, 2.7 MPa or 2.9 MPa.

[0026] The spunlace process of the present invention adopts 6 spunlace steps, and at the same time controls the spunlace pressure range of different numbers of steps, so that the entanglement effect of the cellulose fiber layer is better and the uniformity is better. When the pressure of the first two spunlaces is too high, the fiber web is easily broken up, resulting in voids in the fiber web and affecting the surface uniformity. When the pressure of the last four spunlaces is too low, the fiber entanglement is too small, which in turn affects the adsorption effect of the mask cloth on the mask liquid. When the pressure of the last four spunlaces is too high, the fibers between the skin-friendly layers are entangled more tightly and the hardness is high, affecting the skin feel of the product.

[0027] Preferably, the hydroentanglement process in step (1) is followed by a drying process.

[0028] Preferably, the drying temperature is 130-140°C, and the drying time is 5-15 min. For example, the temperature may be 131°C, 133°C, 135°C, 137°C or 139°C, and the drying time may be 6 min, 8 min, 10 min, 12 min or 14 min.

[0029] In the present invention, when the drying temperature is too low, the film cloth cannot be completely dried, and when the temperature is too high, the film cloth is too hard, affecting the skin feel of the mask product. Only when the drying temperature is controlled within the above range can the final mask cloth have a better skin feel.

[0030] Preferably, the adhesive in step (2) is PUR hot melt adhesive.

[0031] Preferably, the amount of the adhesive is 2-5 g / m 2 , for example, it can be 2.5g / m 2 , 3g / m 2 3.5g / m 2 , 4g / m 2 or 4.5g / m 2 wait.

[0032] Preferably, the compounding in step (2) is followed by a standing treatment.

[0033] In the present invention, the middle layer is compounded with the cellulose fiber layers on both sides and then left to stand for a static treatment, so that the layers can be better cross-linked and cured, ensuring that the product will not be delaminated or lint-shed.

[0034] Preferably, the standing temperature is 30-40°C, for example, 31°C, 33°C, 35°C, 37°C or 39°C.

[0035] Preferably, the standing time is 5-10 h, for example, 5 h, 6 h, 7 h, 8 h, 9 h or 10 h.

[0036] Other specific point values ​​within the above numerical ranges can be selected and will not be described in detail here.

[0037] In a third aspect, the present invention provides a use of the non-irritating, lifting, and firming facial mask cloth as described in the first aspect in preparing a facial mask.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] (1) The present invention uses PU fiber as the elastic middle layer and cellulose fiber layers on both sides, wherein the middle layer has good elasticity. After being made into a membrane cloth, it can provide good elasticity. The cellulose fiber layer can be made very soft by controlling the fineness. The surface of the prepared membrane cloth is very delicate and soft, and can provide a good skin feel. Since the cellulose fiber layer is in contact with the skin, the final mask cloth is very friendly to the skin, has no irritation, and is safer and gentler.

[0040] (2) The present invention uses processes such as spunlace and compounding to make the structure of the mask cloth more stable, and it is not easy to deform or shift when it fits the skin. In addition, by punching the middle layer, it can ensure that the mask liquid in the mask can better infiltrate the entire mask cloth. DETAILED DESCRIPTION

[0116] Test Example 2

[0117] The mask cloths of Examples 1-8, 10-13 and Comparative Examples 1-4 were soaked in water for 20 seconds, and then 102 volunteers were selected and randomly divided into 17 groups, with 6 people in each group, and the products after the above treatment were tried for 30 minutes, and then sensory evaluation was performed on the softness of the fit, lifting and firming effect, and irritation (the higher the score, the less irritation), using a 5-point system: 4.5 points and above, indicating very good, very satisfactory; 4-4.5 points are good; 3-4 points are moderately acceptable; 3 points or less are not good, unacceptable.
