Description

Dry and comfortable bamboo fiber spunlace non-woven fabric

Technical Field

The utility model belongs to the technical field of sanitary napkins, and particularly relates to a dry and comfortable bamboo fiber spunlace non-woven fabric.

Background

The sanitary towel is a substance with absorption capacity, the main material is cotton, non-woven fabric, paper pulp or high molecular polymer and high molecular polymer composite paper formed by the above materials, the design of the side edge is mainly used for preventing side leakage, and because the side edge and the sanitary towel body can present a certain angle when in use, the sanitary towel using the side edge made of soft materials is favored by women, the sanitary towel is divided into three layers which are respectively a surface layer, an absorption core and a bottom layer, and the back adhesive of the sanitary towel is a waterproof material, can retain menstrual blood in the sanitary towel and is used for absorbing the menstrual blood flowing out from the vagina when the women go wet. When in use, the existing sanitary towel has slow liquid absorption speed of the surface layer, thereby leading users to feel uncomfortable such as sultry, moist and the like. There is a need to improve the dryness of nonwoven fabrics used in the facing layers of existing sanitary napkins.

SUMMERY OF THE UTILITY MODEL

The utility model provides a dry and comfortable bamboo fiber spunlace non-woven fabric to solve the problems in the prior art.

In order to achieve the purpose, the technical solution of the utility model is as follows:

a dry bamboo fiber spunlace non-woven fabric comprises an upper layer and a lower layer, wherein the upper layer and the lower layer are compounded through hot melt adhesive; the upper layer is provided with a convex part and a concave part which are arranged at intervals; the depressed part is a corona treatment part.

Preferably, the protruding part and the recessed part are in an elongated structure.

Preferably, the upper layer is formed by cross lapping of corn fibers and bamboo fibers.

Preferably, the upper layer is formed by cross lapping of viscose fibers and bamboo fibers.

Preferably, the lower layer is formed by parallel lapping of bamboo fibers.

The utility model has the beneficial effects that:

the utility model provides a depressed part is corona treatment portion, through carrying out corona treatment, changes its surface tension for the infiltration rate of liquid reduces the dwell time of liquid on the surface, can improve the dry and comfortable nature of surface course when being used for sanitary towel, thereby simultaneously because the leakage problem of sanitary towel can also effectively be reduced to the menstrual blood can permeate fast.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

In addition, the descriptions related to "first", "second", etc. in the present invention are only for descriptive purposes and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "connected," "secured," and the like are to be construed broadly, and for example, "secured" may be a fixed connection, a removable connection, or an integral part; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In addition, the technical solutions in the embodiments of the present invention may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination of technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

Referring to fig. 1 to 2, a dry bamboo fiber spunlace nonwoven fabric comprises an upper layer 1 and a lower layer 2, wherein the upper layer and the lower layer are compounded through hot melt adhesive; the upper layer 1 is provided with convex parts 11 and concave parts 12, and the convex parts 11 and the concave parts 12 are sequentially arranged at intervals; the depressed part is a corona treatment part. Above the non-woven fabrics upper strata form rectangular form three-dimensional bellying 11 and the 12 structures of depressed part through the three-dimensional embossing roller of bar, wherein the depressed part is corona treatment portion, through corona treatment, changes non-woven fabrics surface tension for the infiltration rate of liquid, reduce the dwell time of liquid on the surface, improve its dry and comfortable nature.

Further, the upper layer is formed by cross lapping of corn fibers and bamboo fibers; or the upper layer is formed by cross lapping of viscose fibers and bamboo fibers. The corn fiber has high strength, good moisture absorption and air permeability and comfortable skin touch and hand feeling, and is cross-lapped with the bamboo fiber to prepare the non-woven fabric which can improve the bacteriostatic property, the moisture absorption and the air permeability and the comfort of the sanitary towel when used for the sanitary towel. In addition, the viscose fiber also has good absorption and ventilation properties, and can be cross-lapped with bamboo fiber to prepare non-woven fabrics which can improve the bacteriostasis, moisture absorption and ventilation properties and the like of the sanitary towel.

Further, the lower layer 2 is formed by parallel lapping of bamboo fibers. The bamboo fiber has the characteristics of good air permeability, instant water absorption, strong wear resistance, good dyeing property and the like, has the functions of natural antibiosis, bacteriostasis, mite removal, deodorization and ultraviolet resistance, and is very suitable for sanitary towel products.

The specific implementation mode of the utility model is as follows:

mixing the upper layer of bamboo fiber with corn fiber, or mixing the bamboo fiber with adhesive fiber, and then cross-carding by a carding machine to form a cross non-woven fabric layer; through low-frequency discharge treatment, various active factors are generated on the surface layer of the non-woven fabric, the surface energy of the non-woven fabric on the surface layer is changed, the surface tension of the non-woven fabric is reduced, so that liquid can quickly penetrate through the surface without staying, and the moisture absorption performance of the surface layer is not changed; compounding the upper surface layer and the lower surface layer which are subjected to corona treatment, and then carrying out spunlace reinforcement through 6-8 spunlace heads; and drying and rolling the reinforced non-woven fabric to form the base fabric.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
