Description

Weak-acid non-woven fabric for paper diapers
Technical Field
The utility model relates to a technical field of non-woven fabrics for nursing especially relates to a faintly acid non-woven fabrics for panty-shape diapers.
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 consumption and use of disposable sanitary products of people rises 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 2016 exceeds 850 hundred million yuan, so that the increase is rapid.
Disposable diapers are an important component of disposable sanitary articles. The disposable diapers for babies and adults are generally constructed of a surface layer for allowing liquid to pass through, a baffle layer for preventing liquid from permeating, a bottom layer for preventing liquid from permeating, and an absorbent body provided between the surface layer and the bottom layer, which are joined to each other at their ends. In the use process, the non-woven fabric directly contacts the skin of a consumer, the performance of the surface layer material directly determines the use experience of the consumer, so that the characteristic of the non-woven fabric surface layer is the key performance of the paper diaper, if the non-woven fabric has the performances of skin friendliness, dryness and the like, the excellent consumption experience can be given to the consumer, the adverse factors in the use of the paper diaper are reduced, and the comprehensive performance of the paper diaper is greatly improved.
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, 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 reason for this is mainly the following points:
(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 caused by irritation reaction to the skin 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, and after contacting with the skin, the skin can be stimulated to cause adverse reactions such as flushing, eczema and the like on the surface of the skin, and the quality of the fabric and downstream products is greatly reduced.
Disclosure of Invention
The utility model aims at providing a collect quick infiltration to the water conservancy diversion layer, liquid diffusion is as an organic whole with the function of preventing liquid to return to ooze, the above-mentioned problem of each function mutual interference, aim at providing one kind and realize each function by the water conservancy diversion layer of difference respectively, can better exert its quick infiltration, liquid diffusion with prevent liquid to return to ooze the function, make liquid fully diffuse the infiltration, the dry and comfortable and the stock solution of lower layer material of upper fabric has been guaranteed, change the pH value of non-woven fabrics simultaneously, make the pH value of non-woven fabrics more be close to the pH value of consumer's skin, reduce the stimulation in the use weak acid non-woven fabrics for panty-shape diapers of weak acid cloth for the water conservancy diversion diaper.
