Detailed Description

It is easily understood that, according to the technical solution of the present invention, a plurality of alternative structural modes and implementation modes can be proposed by those skilled in the art without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical solutions of the present invention, and should not be considered as limiting or restricting the technical solutions of the present invention in their entirety or in any other way.

An embodiment according to the present invention is shown in conjunction with fig. 1. The utility model provides a paper diaper adjusts temperature, this paper diaper from top to bottom includes surface course, water conservancy diversion layer 3, absorbs core 5 and refuses water bottom 6 in proper order, and the surface course is mutually compound through coating the hot melt adhesive between layer 3 and water conservancy diversion layer and the water conservancy diversion layer 3 and the absorption core 5, and the hot melt adhesive sprays the volume and is 0.3 g/piece paper diaper, 0.45 g/piece paper diaper respectively.

The surface layer is divided into an upper surface layer 1 and a lower surface layer 2 which are Y-shaped section multi-affinity ES fiber layers, compared with ES fibers with round sections, the surface layer can carry more air-conditioning microcapsules, particularly, the specific surface area of superfine denier profiled fibers is larger, the number of fibers of the surface layer with the same gram weight is larger, the number of carried air-conditioning microcapsules is more, and the temperature control effect of the surface layer directly contacting with the skin of a baby is more obvious. The surface layer can also adopt other special-shaped ES fibers such as triangle, trilobal, cross, polygon and the like.

The fiber fineness of the upper surface layer 1 is smaller than that of the lower surface layer 2, specifically, the fiber fineness of the upper surface layer 1 is 1.0D, and the fiber fineness of the lower surface layer 2 is 2.0D. The upper surface layer 1 has low disorder degree, the fiber is longitudinally arranged more and accounts for 50 percent of the surface layer, the lower surface layer 2 has high disorder degree, and the fiber arrangement has anisotropy and accounts for 50 percent of the surface layer. It will be appreciated that the proportion of the upper face layer 1 to the face layer may be reduced but should be greater than 40% and the proportion of the lower face layer 2 to the face layer may be increased but should be less than 60%.

When the liquid contacts the surface layer, the upper layer 1 is longitudinally arranged due to the fibers, the fibers are fine and dense, the pores are small, the longitudinal liquid guiding and moisture guiding effects are strong, the lower layer 2 is randomly arranged due to the fibers and is large in pore size, the liquid can be rapidly diffused to the flow guiding layer by penetrating through the pores of the upper layer 1, the moisture guiding effects of the fine denier fibers and the mechanical perforation of the cloth cover, and the liquid is also diffused to the two ends of the absorption core body 5 by the flow guiding layer 3 with large vertical and horizontal ratios, so that the absorption core body 5 can fully absorb the liquid. The diaper not only can provide soft and fine touch feeling through the superfine denier upper surface layer, reduce the friction between fibers and the skin and relieve the phenomenon of red buttocks, but also can quickly conduct moisture and absorb moisture through the matching of the thick denier lower surface layer 2, the diversion layer 3, the perforated structure and the absorption core body 5, thereby ensuring the dryness and comfort of the diaper.

Further, the surface layer has a thickness of 0.5mm, a grammage of 30g/m2, an aspect ratio of 4.6, and a plurality of holes having a hole diameter of not more than 1.0mm, preferably 0.6 mm. Preparing fiber web on the surface layer under the environment conditions of 26 ℃ of temperature and 40% of relative humidity, drying by adopting hot air at 140 ℃ under low tension for 16s, and preparing into mother rolls. The mother coil is molded by passing through a needle roller at 106 ℃ under low tension and cold air at 20 ℃ and finally molded. The preparation method of the surface layer can also adopt the following steps: the ES fibers and the bonding fibers of the air-conditioning microcapsules are reinforced by hot air, the non-ES fibers of the air-conditioning microcapsules are reinforced by hot air by using hot-melt powder, the non-ES fibers of the air-conditioning microcapsules are reinforced by spunlace, and the non-woven fabric is directly coated with the air-conditioning microcapsules.

In this embodiment, air conditioning microcapsules (i.e., PCM, nano-microcapsules) are uniformly disposed on the upper layer 1 and the lower layer 2, and when the temperature reaches a certain value, the physical form of the microcapsules is transformed (solid-liquid), thereby realizing heat absorption and heat release functions. Liquid contacts the air-conditioning microcapsule, and then absorbs or releases heat through the phase change effect of solid-liquid conversion of the microcapsule, so that the micro-environment temperature of the baby skin during liquid absorption of the paper diaper can be immediately adjusted.

The outer surface of the absorption core body 5 is coated with dust-free paper 4, and the absorption core body 5 is added with an adsorption material which is macromolecular water-absorbent resin particles. When the baby wears the paper diaper, the micro-environment of the skin of the baby, the surface layer of the paper diaper and the air can be adjusted, and the comfortable body feeling is kept.

In this example, the flow guiding layer 3 had a thickness of 0.3mm, a grammage of 30g/m2, an aspect ratio of 6, and a fiber fineness of 6.0D. The water-repellent back sheet 6 had a thickness of 0.3mm, a grammage of 20g/m2, an aspect ratio of 4.6 and a fiber fineness of 1.5D. The water-repellent bottom layer 6 is provided with a plurality of holes, and the diameter of each hole is 0.6 mm.

It is understood that the facing layer in combination with the absorbent core provides the diaper with excellent absorbency, dryness and temperature regulation, and can be used in sanitary napkins or other disposable absorbent articles. The surface layer can be embossed and perforated, so that the gram weight of the surface layer is increased, and the temperature regulation effect of the surface layer is enhanced.

In order to test the performance of the diapers, the temperature regulating function thereof was tested and compared with conventional products, as shown in table 1.

As can be seen from Table 1, when the solution temperature 1 is higher than the storage temperature, the temperature of the surface layer after imbibing liquid in the examples is faster than that in the comparative examples; when the solution temperature 2 is lower than the storage temperature, the temperature rise after imbibing the surface layer in the examples is faster than that in the comparative examples.

The utility model provides a paper diaper adjusts temperature not only can be high-efficient ventilative, and the imbibition drenches, can also change the temperature regulation that realizes in different temperature environment through air conditioner microcapsule's solid-liquid, provides comparatively comfortable body and feels the environment.

The technical scope of the present invention is not limited to the content in the above description, and those skilled in the art can make various modifications and alterations to the above embodiments without departing from the technical spirit of the present invention, and these modifications and alterations should fall within the protection scope of the present invention.
