Description
Technical Field
The utility model relates to the technical field of physiological health care products, in particular to a physiological health care product with a pressure-bearing self-closing type breathable leakage-proof combined layer/body.
Background
Sanitary care products for absorbing physiological excretions, such as sanitary napkins, panty diapers, and pads, are mainly used for absorbing physiological excretions of the human body, such as menstrual blood, urine, and the like. Such sanitary products are mainly composed of three major core parts, namely: a top layer, an absorbent layer (body), a leakage-proof layer, etc. Since human waste is rich in moisture, leakage prevention is one of the most important core functions of sanitary care products in addition to absorption capacity.
The health care products are mostly used for private parts, and the private environment is in a 'stuffy' state for a long time due to poor air permeability of products, so that rapid breeding and fission of microorganisms in a small environment are induced and accelerated, and a series of health problems of the private parts are caused.
The PE breathable waterproof film adopts inorganic material calcium carbonate microparticles to be melt-mixed with PE high polymer materials, and is stretched after film formation, so that gaps in a microscopic state are formed between the calcium carbonate microparticles and PE, gas can be allowed to pass through in a use state, and liquid can be blocked at the same time, so that the effects of ventilation and leakage prevention are achieved. Unfortunately, the air permeability of the material can only relatively improve the small environment of the private part, and the aim of thoroughly eliminating the damp and improving the excellent experience can not be achieved.
If the air permeability detection standard (GB/T5453 or ISO 9237) of the textile fabric is adopted to detect market products or air permeability leakage-proof materials, the air permeability of the PE air permeability film leakage-proof layer used for the sanitary care products is about 0.05-1.00 mm/s; the air permeability of the sanitary article with the hydrophobic non-woven fabric leak-proof layer structure should be more than or equal to 40mm/s. The multi-party verification proves that the air permeability of the sanitary article is more than 20mm/s in order to truly realize the use requirement of basically eliminating the stuffy and wet feeling.
In order to ensure the leakage-proof property of the product in use, the method of improving the absorption capacity or adding a leakage-proof buffer layer has to be adopted, but the method not only makes the structure of the product complex and increases the thickness of the product, but also makes the cost of the product virtually high, and finally makes the product so good, and the product is very challenging in use experience and marketing.
In summary, the breathable and leakproof mechanism of the high-permeability sanitary care product with the non-woven fabric leakproof layer is to perform special hydrophobic treatment (after-finishing on fibers or base cloth by using a hydrophobic finishing agent/material) on the breathable and leakproof layer of the non-woven fabric so as to realize ventilation and leakproof under the use condition. The leakage of such products is caused by the fact that after the products are fully absorbed, the products leak due to insufficient leakage resistance of the back/bottom leakage-proof layer/material of the products against the penetration force of the liquid under the use pressure, such as the instantaneous pressure when the body sits down or lies down, the clamping force of two legs, the product contusion caused by walking, etc., due to the flowable liquid stored in the absorber. Obviously, such techniques or products may be prone to leakage of the product due to performance fluctuations of the material such as the absorbent body, the breathable anti-leakage layer, and individual differences in the shape and use scenario of the user.
Therefore, we propose a physiological health care product with a pressure-bearing self-closing type breathable leakage-proof combined layer/body, so as to thoroughly solve the problems set forth in the above.
