CN1301090C - Hygienic articles with bacteriostatic hot melt adhesives - Google Patents

Abstract

The invention discloses a sanitary product with a hot-melt adhesive capable of inhibiting bacteria. The sanitary product is formed by combining a non-woven fabric, a water-absorbing body and a waterproof layer from top to bottom, and the non-woven fabric and the water-absorbing body are bonded by a hot-melt adhesive. Meanwhile, the hot-melt adhesive is composed of synthetic rubber, a tackifier, a softening oil and a bacteriostatic agent, and has both bonding and bacteriostatic effects, making the sanitary product more sanitary and safer.

Description

Hygienic articles with bacteriostatic hot melt adhesives

technical field

The present invention relates to a hygienic product with antibacterial hot-melt adhesive, more specifically, relates to a kind of use of antibacterial hot-melt adhesive to bond the non-woven fabric and water-absorbing body in order to inhibit the use of Hygienic products for bacteria that grow during the process or bacteria that are carried by the material of the paste itself.

Background technique

With the improvement of the national health knowledge level, no matter in the manufacture or use of sanitary products, more and more attention is paid to personal hygiene. The hygienic products here generally refer to products such as sanitary napkins, panty liners or diapers (sheets), that is, the sanitary products have the common structural characteristics of combining non-woven fabrics, water-absorbing bodies and waterproof layers.

And the general hot-melt adhesive that this hygienic article uses is only as simple adhesive, does not have antibacterial effect. Therefore, the creators of the present invention have finally created a bacteriostatic hot-melt adhesive with their tireless spirit and rich professional knowledge and experience. This hot-melt adhesive is not only used for bonding hygienic The non-woven fabric and water-absorbing body of the article can also inhibit the bacteria that grow during use or the bacteria that are carried by the material of the pasted object itself, making the sanitary article more hygienic and safe.

Contents of the invention

The main purpose of the present invention is to provide a sanitary product with antibacterial hot-melt adhesive.

The hygienic articles with antibacterial hot-melt agent in the present invention combine non-woven fabric, water-absorbing body and waterproof layer from top to bottom, and adopt hot-melt adhesive bonding between non-woven fabric and water-absorbing body; Simultaneously, this hot-melt adhesive is made of Composed of synthetic rubber, tackifier, softening oil and antibacterial agent, it has both adhesive and antibacterial effects, making sanitary products more hygienic and safe.

Detailed ways

The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the antibacterial hot-melt adhesive of the present invention mainly consists of about 10-40% synthetic rubber, about 30-70% tackifier, about 5-30% softening oil and about 0.5- 5% antibacterial composition. Among them, the synthetic rubber can be styrene-butadiene, styrene-butadiene-styrene, styrene-isoprene-styrene, styrene-ethylene-propylene-styrene or styrene-ethylene-butylene ene-styrene; tackifier can be hydrogenated petroleum resin, rosin resin, terpene resin; antibacterial agent can be silver series inorganic compounds.

The hot melt adhesive composed of the above has the following characteristics:

1. It is solvent-free.

2. Operate in a molten state at a temperature of about 120 degrees Celsius to 180 degrees Celsius, and it is safe.

3. Absorb bacteria physically.

4. Use active oxygen and silver ions to produce antibacterial effect.

5. It can inhibit the bacteria that breed during use or the bacteria contained in the material of the paste itself.

Since the hot-melt adhesive of the present invention has antibacterial effect, it is suitable for use in sanitary products, such as sanitary napkins, panty liners or paper diapers (cloth). As shown in Figure 2 and Figure 3, the sanitary product is a combination of non-woven fabric 1, water-absorbing body 2 and waterproof layer 3 from top to bottom. agent 4 to bond the two, and the hot-melt adhesive 4 has a bacteriostatic effect, which can inhibit the growth of bacteria in the process of manufacturing and use, or can inhibit the non-woven fabric 1, water-absorbing body 2 and Bacteria carried by materials such as the waterproof layer 3 itself. As shown in Figures 2 to 5, the above-mentioned hot-melt adhesive 4 is distributed on the bottom surface of the non-woven fabric 1 in the form of many spirals, fibers or scales, so that the hot-melt adhesive has gaps 5 without hindering the water-absorbing body 2 from absorbing the non-woven fabric 1 on the liquid.

As can be seen from the above description, the present invention clearly has the following advantages:

1. The hot-melt adhesive of the present invention can not only be used as an adhesive, but also has antibacterial effect.

2. Since the hot-melt adhesive of the present invention has antibacterial effect, it is more hygienic and safer to use it as an adhesive to make sanitary products.

To sum up, the embodiment of the present invention can indeed achieve the expected use effect.
