Description

A compound water conservancy diversion layer structure of multilayer for urine trousers
Technical Field
The utility model relates to a technical field of non-woven fabrics fabric for nursing especially relates to a compound water conservancy diversion layer structure of multilayer for urine trousers.
Background
According to the relevant national regulation, the disposable sanitary article refers to: the disposable sanitary towel is a variety of daily necessities which are discarded after being used once, are in direct or indirect contact with a human body and are used for achieving the purposes of physiological sanitation or health care (antibiosis or bacteriostasis) of the human body. With the continuous improvement of the living standard of people in China and the continuous popularization of the sanitary concept, the proportion of the consumption and the use of the disposable sanitary products of people is increased year by year, for example, the sales of the disposable sanitary products in China in 2004 is about 145 hundred million yuan, and the sales of the disposable sanitary products in China in 2013 is 621 hundred million yuan, so that the increase is rapid.
Disposable diapers are an important component of disposable sanitary articles. Disposable infant and adult pants are generally constructed of a liquid-pervious topsheet, a liquid-impervious backsheet, and an absorbent body interposed between the topsheet and the backsheet, which are joined to each other at their ends. When the diversion layer is used, the functions of quickly seeping, dispersing liquid and preventing liquid from seeping back into the whole are needed to be achieved. The properties of the baffle often determine the amount of liquid storage and dryness of the end product.
The ever expanding market for disposable sanitary products not only drives the market for nonwoven fabric flow guide layer materials at the upstream of the market, but also puts more strict requirements on the quality, performance and the like of the nonwoven fabric flow guide layer materials. However, the development of the surface layer non-woven fabric flow guiding layer in the existing domestic market is still focused on the low-end product for the competition of blanching, and the high-quality flow guiding layer fabric is still the target actively pursued in the field, but the commercialization and marketization are difficult to realize, and the reasons for the whitening competition are mainly as follows:
(1) infiltration: as the middle surface layer for bearing the upper part and the lower part, the flow guide layer acts like a high-speed channel. The speed of the liquid infiltration can directly influence the dryness of the skin contact surface layer. If the liquid on the surface layer of the diaper can not quickly pass through the diversion layer to finish infiltration, the dryness degree of the surface layer can be influenced. Liquid is silted up on the top layer for top layer surface fabric water content is too high, not only leads to the surface course moist, influences the sense of touch, arouses user's discomfort, still can influence the imbibition performance on top layer greatly, shortens terminal product's life, seriously influences the product quality.
(2) Flow guiding: the most direct function of the flow guiding layer is to perform the function of liquid diffusion. However, the fabric in the prior art has low attention on the aspect of the flow guide function, and most of the middle-layer fabrics can only realize the liquid passing function and cannot finish the liquid diffusion. When the liquid is intensively infiltrated at a local position, the local position of the absorbent core body can reach a saturated state in a short time, and the other positions do not show the liquid absorption effect. The service life of the product is greatly shortened, the waste is serious, and the product quality is reduced.
(3) Water locking: the biggest problems of the existing disposable sanitary products including diaper pants are that the dryness is not enough, and skin problems such as red rash and the like are easily caused. The anti-reverse-osmosis water-locking performance of the current diversion layer with the single-layer structure is poor, liquid enters the absorption core body through the diversion layer, and under the condition of saturation and compression, the liquid returns to the surface fabric through the diversion layer again, so that the fabric is wet, adverse reactions such as flushing, eczema and the like on the surface of the skin can be caused after the fabric is contacted with the skin, and the quality of the fabric and downstream products is greatly reduced.
Disclosure of Invention
