Description

Technical Field

[0001] The invention relates to a facial mask sheet material, and in particular to a three-layer elastic composite lifting membrane cloth based on camellia and a processing method thereof. Background Art

[0002] Asphalt waterproofing membrane refers to a roll of material made of asphalt material, tire material and anti-sticking material on the surface. Non-woven fabric, also known as non-woven fabric, is a membrane fabric made by laying fibers, combing and forming, and then spunlacing by machine. Its weave structure is mainly completed by machine. The fiber characteristics require that the length should not exceed 51mm, basically 38mm, and the denier is basically 0.6-1.56dtex. And the current spunlaced membrane fabrics are basically 1 layer. Whether the entanglement degree and physical property indicators of the fabric surface meet the standards mainly depends on the fiber and production parameters.

[0003] At present, in the spunlace production unit, the physical property index of plant fiber is undoubtedly the lowest. Not only in the mask sector, but also in the textile sector, plant fiber is always the most popular, which represents various natural information such as natural, degradable, and pollution-free. However, because plant fiber is artificially implanted with natural plant oil or added with specimens, the overall hardness of the fiber decreases during spunlace production, the entanglement effect is low during production, and the spunlace production parameters are reduced. However, products with softness, stickiness, and naturalness are particularly attractive to customers.

[0004] With the development of society, people's requirements for beauty products are constantly increasing. In order to meet the needs of market consumers, existing technologies can only try to reduce costs from essences, packaging materials and finished products. As a result, many products now need to meet the standard of single-layer use in order to meet customer requirements.

[0005] The applicant has adopted a single-layer camellia mask cloth structure in existing facial mask products. This structure is easily deformed and folded and difficult to separate. In addition, due to the soft and sticky characteristics of the camellia mask cloth fibers themselves, it is difficult to open, that is, it is difficult to separate from the face or difficult to separate after folding. Summary of the invention

[0006] In order to solve the problems existing in the above-mentioned technology, the present invention provides an improvement on a single-layer camellia membrane cloth so as to obtain an easy-to-separate and soft property of the camellia membrane cloth.

[0007] The present invention provides a three-layer elastic composite lifting membrane cloth, which comprises a first outer layer, a middle layer and a second outer layer in sequence, wherein the first outer layer and the second outer layer are plant fiber membrane cloths, and the middle layer is elastic cloth:

[0008] The facial mask product of the present invention improves the properties of the two outer plant fiber membranes by introducing an elastic layer, so that the facial mask sheets are easier to separate and the compactness of the facial mask sheets is improved.

[0009] Preferably, the first outer layer and the second outer layer are camellia fiber layers.

[0010] Preferably, the three-layer elastic composite lifting membrane cloth is a facial mask sheet, the weight of the facial mask sheet is 90 grams, the weight of the camellia fiber layer is 22.5 grams, and the weight of the middle layer is 45 grams.

[0011] Preferably, the first outer layer and the second outer layer have the same weight, and the weight ratio of the first outer layer to the middle layer is 1:2.

[0012] The three-layer elastic composite lifting membrane cloth provided by the present invention is an improved elastic cloth. The components of the elastic cloth include cotton, elastic band and polyimide nanoparticles. The weight proportion of cotton is 95%-98%, the proportion of elastic band is 1%-3%, and the rest is polyimide nanoparticles.

[0013] Cotton and rubber band are woven into an elastic layer, which is then impregnated with a polyimide nano solution, taken out, drained and dried to obtain an improved stretch fabric.

[0014] The present invention provides a method for processing a three-layer elastic composite lifting membrane cloth, which comprises the following steps:

[0015] S1: Pick up materials, pick up the required fibers and send them out of the warehouse in advance to prepare for subsequent production;

[0016] S2: Fiber feeding, removing fiber raw material packaging, conducting appearance inspection, and feeding into the equipment after inspection;

[0017] S3: opening and mixing, the fibers are dispersed and put into the feeding unit, and the fibers are slowly fed into the pipeline from the feeding port for opening and mixing;

[0018] S4: AB double combing, the fibers enter the combing and laying unit, and are automatically distributed into the double laying unit;

[0019] S5: Grid connection, which makes the fibers evenly dispersed, settled and formed in the inclined grid former, and obtains a three-dimensional network structure of randomly arranged fibers, providing structural guarantee for the subsequent hydroentanglement;

[0020] S6: Hydroentanglement, using dense and fine water needles to perform high-pressure hydroentanglement reinforcement on the fiber web layer, causing the fibers to shift, interweave, and entangle, ensuring the physical strength of the final product;

[0021] S7: After-finishing, through the after-finishing, the three-dimensional net is pressed for the second time to remove part of the free water after spunlacing, reduce the moisture, and make the composite product more compact;

[0026] Figure 1 This is a description of the production process of the camellia three-layer elastic composite lifting membrane cloth spunlace nonwoven material of the present invention. DETAILED DESCRIPTION

[0027] First embodiment:

[0028] The present invention provides a three-layer elastic composite lifting membrane cloth, which comprises a first outer layer, a middle layer and a second outer layer in sequence, wherein the first outer layer and the second outer layer are plant fiber membrane cloths, and the middle layer is elastic cloth.

[0029] Second embodiment:

[0030] The first outer layer and the second outer layer are camellia fiber layers. The present invention uses three-layer spunlace technology to obtain a three-layer elastic composite lifting membrane cloth of A+B+A structure type, A is camellia fiber, and B is elastic cloth. The applicable scope of the product of the present invention: facial mask plate; applicable population: all populations; product properties: elasticity, lifting, and skin tightening.

[0031] The three-layer elastic composite lifting membrane fabric of the present invention is a facial mask sheet, the weight of the facial mask sheet is 90 grams, the weight of the camellia fiber layer is 22.5 grams, and the weight of the middle layer is 45 grams. Preferably, the weight of the first outer layer and the second outer layer is the same, and the weight ratio of the first outer layer to the middle layer is 1:2.

[0032] Third embodiment:

[0033] The three-layer elastic composite lifting membrane cloth provided by the present invention is an improved elastic cloth, and the components of the elastic cloth include cotton, elastic and polyimide nanoparticles, the weight proportion of cotton is 95%-98%, the weight proportion of elastic is 1%-3%, and the rest is polyimide nanoparticles. In a specific embodiment, the weight proportion of cotton is 98%, the weight proportion of elastic is 1%, and the rest is polyimide nanoparticles; or the weight proportion of cotton is 97%, the weight proportion of elastic is 1.5%, and the rest is polyimide nanoparticles;

[0034] The preparation process of polyimide nano solution is:

[0035] Step 1: Weigh polyimide and water in a ratio of 1:10 and set aside;

[0036] Step 2: Add the polyimide nanoparticle powder obtained in step 1 into deionized water, stir and disperse thoroughly to obtain a solution for later use; alternatively, other existing technologies can be used to prepare a polyimide nanoparticle solution;

[0037] Cotton and rubber band are woven into an elastic layer, which is then impregnated with a polyimide nano solution, taken out, drained and dried to obtain an improved stretch fabric.

[0038] In a specific embodiment, the finished product of camellia stretch fabric has a gram weight of 90 grams, of which the middle layer of stretch fabric is 45 grams and the water-locking layers on both sides are 22.5 grams each. The stretch fabric is an improved stretch fabric product. The ordinary existing stretch fabric is not only elastic and soft, but also has a low density, which is not suitable for compounding. During the spunlace production process, the shrinkage ratio of the elastic force is required to be 50%. If the basic finished product middle layer is 45 grams, the gram weight before shrinkage is 90 grams, and the square gram weight doubles after shrinkage.

[0039] Serial number Weight Width Weight after shrinkage Elasticity density Pressure value Prior art stretch fabric 45 3.3 84 0.47 0.58 86 Improved stretch fabric 45 3.3 90 0.79 0.84 123

[0040] Spunlace forming is a high pressure forming method. As shown in the table above, for the same weight and width:

[0041] The gram weight of the existing elastic fabric after shrinkage is less than that of the improved elastic fabric;

[0042] The elasticity value of the existing elastic fabric is less than that of the improved elastic fabric;

[0043] The density of the prior art stretch fabric is less than that of the improved stretch fabric;

[0044] The compression value of the prior art elastic fabric is less than that of the improved elastic fabric;

[0045] From the table above, we can see that the water pressure requirement for three-layer production is 110pa, and only the pressure value of the improved stretch fabric is obviously greater than 110. The pressure value is its controllable pressure. If it is lower than the water pressure value of the machine, the machine will automatically alarm and stop during production.

[0046] Comparative Example 1

[0047] Remove the finishing process, and keep other normal processes unchanged. The importance of finishing in the production process is mainly reflected in: the actual shrinkage of the fabric surface and the secondary compaction operation of the fabric surface. Without the finishing process, the finished fabric may have insufficient composite compactness, uneven weight distribution, and insufficient shrinkage. The composite surface is easy to tear in the dry state, and will be directly washed away after soaking in the essence containing chemical ingredients for 15 minutes.

[0048] The elasticity value is directly 0; the fabric has no adhesion; and the middle layer is directly melted away. Therefore, this solution is not advisable.

[0049] Fourth embodiment:

[0050] The present invention provides a method for processing a three-layer elastic composite lifting membrane cloth, which comprises the following steps:

[0051] S1: Pick up materials, pick up the required fibers and send them out of the warehouse in advance to prepare for subsequent production;

[0052] S2: Fiber feeding, removing fiber raw material packaging, conducting appearance inspection, and feeding into the equipment after inspection;

[0053] S3: opening and mixing, the fibers are dispersed and put into the feeding unit, and the fibers are slowly fed into the pipeline from the feeding port for opening and mixing;

[0054] S4: AB double combing, the fibers enter the combing and laying unit, and are automatically distributed into the double laying unit;

[0055] S5: Grid connection, which makes the fibers evenly dispersed, settled and formed in the inclined grid former, and obtains a three-dimensional network structure of randomly arranged fibers, providing structural guarantee for the subsequent hydroentanglement;

[0056] S6: Hydroentanglement, using dense and fine water needles to perform high-pressure hydroentanglement reinforcement on the fiber web layer, causing the fibers to shift, interweave, and entangle, ensuring the physical strength of the final product;

[0057] S7: After-finishing, through the after-finishing, the three-dimensional net is pressed for the second time to remove part of the free water after spunlacing, reduce the moisture, and make the composite product more compact;

[0058] S8: Drying: heating and drying the spunlace fiber web to form a stable structure inside and between the fibers, and to allow the finishing agent to play a corresponding role;

[0059] S9: Rolling, winding into a tube according to the length controlled by the fixed length device;

[0060] S10: Inspection and cutting, re-inspect and cut the finished products according to requirements;

[0061] S11: Pack the finished products as required and then put them into storage.

[0062] The process upgrade of this embodiment provides a production technology involving high-performance camellia materials. The three-layer structure used in this process is a skin-friendly layer, a water-locking layer, and a skin-friendly layer, and the skin-friendly layer is made of ultra-soft natural camellia plant fiber. By adding meshing and post-finishing links, the problem of loose composite of existing mask cloths is solved. It also makes the camellia mask cloth, which originally had no elastic properties, achieve the effect of being able to stretch on all sides, so that users have a tighter and more lifted fit.

[0063]

[0064] Due to the characteristics of the elastic fabric itself, it is not easy to control when it is put on the machine. In order to make the water spunlace penetrate better, we increase the frequency of cleaning the water spunlace head, water needle plate and water needle plate in the water spunlace unit. At the same time, due to its particularity, we customize a needle plate with a special aperture for it, pre-wet the elastic fiber net and increase the entanglement efficiency, and adjust our conventional water spunlace production parameters: from the steps of water spunlace pressurization and production speed reduction, avoid pressure fluctuations caused by water needle plate blockage and use water spunlace pressure as small as possible and with a large number of spunlaces for entanglement, which better solves the problems of faults of three-dimensional nets caused by water needle plate blockage in the water spunlace high-pressure unit.
