Description

Rubber gloves with excellent antibacterial and cosmetic effects and a method of manufacturing the same.

The present invention relates to a rubber glove excellent in antibacterial and cosmetic effects and a method for manufacturing the same, and more specifically, to a raw resin solution such as a latex (Latex) solution containing chitosan or chitosan solution and seaweed powder or extracts thereof ( The present invention relates to a rubber glove manufactured by dipping or coating a mold so that chitosan or chitosan solution and seaweed powder or extract thereof are uniformly distributed or distributed only at a specific site, and a method of manufacturing the same.

In general, rubber gloves are mainly used when housewives wash dishes, wash, etc. at home, washed with raw resin solution such as natural latex liquid, raw rubber liquid, elastic polyurethane liquid, and brine treatment. The dried mold is molded by dipping or coating, then dried, separated from the mold, and then worked up.

One of the major drawbacks of rubber gloves that housewives are widely used in kitchen and home use is that rubber glove is worn for a long time, so that the skin secretion is not only adhered to the inner surface of the rubber gloves, but also adheres to the skin surface. The high humidity inside the microorganisms, in particular, mold and bacteria are easy to breed, which causes skin diseases such as housewife eczema, and wear is not good.

Various techniques for solving the above problems have been developed, but have not been obtained satisfactory results.

On the other hand, chitosan (chitosan) is a substance deacetylated chitin, and composed of a non-molecular chain of β- (1 → 4) -2-acetamide-2-deoxy-D-glucose residue, similar to cellulose. It is a substance found in the exoskeleton of crustaceans such as invertebrates, marine animals, insects, shrimps and crabs, and is used as a hygroscopic and repair agent for cosmetics, as an anticancer agent, and a functional food additive in medicines. have.

In general, chitin obtained from crustaceans is α-chitin, and chitin obtained from invertebrate marine animals is β-chitin. Chitin is insoluble in water and other solvents, while chitosan is soluble in various acidic solvents, such as formic acid or acetic acid, so it is more industrially applied than chitin.

In addition, seaweed such as seaweed and kelp has been widely used for food for a long time, but nowadays, it is known to have an excellent effect on skin beauty, and has been spotlighted as an additive of cosmetics, a raw material of health food, and a diet food.

However, the use of chitosan or chitosan solution seaweed powder or its extract has already been developed.

Accordingly, an object of the present invention is to provide a rubber glove that is excellent in antibacterial and cosmetic effects and does not cause skin diseases even when worn for a long time, and feels well when worn.

In addition to the above object, in order to achieve another object that can be easily expressed in the present invention, chitosan or chitosan solution and seaweed powder or extract thereof in raw resin solution such as natural latex solution, raw rubber solution, elastic polyurethane solution, etc. After adding, washing with water, brine treatment, and drying the mold dried by dipping or coating, and then drying and separating from the mold, and after treatment to prepare rubber gloves, excellent antibacterial and cosmetic effect, even if worn for a long time It was possible to obtain a rubber glove without causing any damage and having a good fit.

1 is a manufacturing process of the rubber glove of the present invention.

The present invention is described in more detail as follows.

Rubber gloves of the present invention is added to the raw resin solution, such as natural latex liquid, raw rubber liquid, elastic polyurethane liquid, chitosan or chitosan solution and seaweed powder or extracts thereof, dipping the mold dried by washing with water and brine treatment Or by coating, molding, drying, separating from the mold, and working up.

The chitosan or chitosan solution and seaweed powder or extracts thereof may be used alone, but are preferably added at the same time. The chitosan used is the higher the deacetylation degree, the higher the amount of chitosan elution from the manufactured rubber gloves, and the higher the amount of chitosan elution, the higher the antibacterial activity. It is desirable to.

The amount of chitosan or chitosan solution and seaweed powder or its extract may vary depending on various conditions, but as the amount is increased, the antibacterial and cosmetic effects are improved, while the strength of rubber gloves is lowered and the life is shortened. shall. In particular, the addition amount should be adjusted according to the use and thickness of the rubber gloves to be manufactured, but in general, 0.1 to 2wt% is added to the raw material resin solution, but preferably, the content does not exceed 4wt%.

When the addition amount of chitosan or chitosan solution and seaweed powder or its extract is less than 0.1wt%, respectively, the effect of addition is insignificant, and even when the addition amount exceeds 2wt%, there is a problem that the strength of the manufactured rubber gloves is lowered. In addition, if the total amount of chitosan or chitosan solution and seaweed powder or its extract exceeds 4wt%, the service life is shortened due to the decrease in strength of rubber gloves.

Chitosan is soluble in weak acid or acidic solution, but not in alkaline solution.Since the raw resin solution for rubber gloves manufacturing is alkaline solution, chitosan is not dissolved. .

In other words, the first method is to micronize chitosan into small particles as much as possible and to force-disperse it in the raw material resin with a stirrer. The second method is to dissolve chitosan in the weakly acidic solution, add it to the raw material resin, and force dispersion. In the invention, any of the above methods may be used.

The algae powder is finely divided into the smallest particles as much as possible, and then added to the raw resin, and then forcedly dispersed with a stirrer or the like, added to the raw resin or the seaweed extract is added to the raw resin as it is stirred.

In the present invention, any one of the above methods may be used. Chitosan or chitosan solution and seaweed powder or its extract may be added and stirred sequentially, or may be added and stirred at the same time. Raw material resin and seaweed powder or extract obtained by stirring chitosan or its dissolved solution are added. The method of mixing a resin liquid and stirring it again can also be used.

Generally, rubber gloves are manufactured in two ways. That is, it is roughly classified into a one-ply product manufactured by dipping or coating a mold only once in a raw material resin for manufacturing rubber gloves and a two-ply product dipped or coated twice. In the application of the present invention, in the case of a one-ply product, it can be easily achieved by adding chitosan or chitosan solution and seaweed powder or extract thereof to the raw material resin solution, and in the case of a two-ply product, only chitosan is in contact with the skin of the hand. Alternatively, chitosan solution and seaweed powder or extracts may be added, so adding chitosan or chitosan solution and seaweed powder or extracts only to the raw resin solution used for the second dipping or coating to maintain the strength of the rubber gloves while maintaining antimicrobial and cosmetic effects. Could get.

In addition, a rubber glove having a fiber attached to a part in contact with a hand when worn may be manufactured.In this case, chitosan or chitosan solution and seaweed powder or extract thereof may be added to an adhesive used for bonding the fiber. Chitosan or chitosan solution and seaweed powder, or extracts thereof may be added to the raw resin solution for secondary dipping or coating.

Rubber gloves of the present invention is preferably washed with a hand-shaped mold to remove foreign substances, and then washed again with brine to facilitate dipping, while at the same time allowing the rubber gloves to be formed to be easily separated from the mold, then dried First, the hand-shaped mold was first dipped into the raw resin solution, brine-treated and dried, and the raw resin containing chitosan or chitosan solution and seaweed powder or extract thereof in an appropriate amount depending on the characteristics and use of the rubber gloves to be manufactured. After dipping again into the liquid and drying, the molded rubber gloves are separated from the mold, and then processed and packaged to obtain a finished product.

As the raw material resin, any raw material resin which can be rubber glove such as natural latex liquid, raw rubber liquid, elastic polyurethane liquid, etc. can be used, and every dipping depends on the required physical properties of the raw material liquid. The addition of various additives can be easily inferred by those of ordinary skill in the art.

In addition, the raw material resin may be added dyes or pigments that can express different colors each time dipping, the concentration and viscosity of the raw material resin solution can be adjusted according to the thickness of the rubber gloves to be manufactured, ease of manufacture and the like.

The following examples and comparative examples illustrate the invention in more detail, but do not limit the scope of the invention.

Example 1

Wash the hand-shaped mold to remove foreign substances, then wash again with brine and dry to prepare the mold.

The hand-shaped mold was then dipped into a dipping tank filled with natural latex solution, brine-treated and dried, and a chitosan or chitosan solution and an algae powder or extract thereof having an 80% deacetylation rate were applied to the natural latex, respectively. After dipping the mold after the first dipping into the natural latex solution added by 2wt%, the molded product was worked up to obtain rubber gloves.

The prepared rubber gloves were first washed with water, and each of the 4 specimens of No. 4 of KSM 6518 was collected, placed in a Erlenmeyer flask containing 10 ml of distilled water, and extracted for 2 hours in a 60 ° C. hot water bath. After sterilization by adding, Fusarium solani (fungus) was incubated for 3 days, and the number of bacteria was 62 when the number of bacteria of the rubber glove without chitosan was used as test specimen was 100. .

Example 2 and Comparative Example 1

The rubber gloves were prepared in the same manner as in Example 1 except that the deacetylation degree of chitosan was 90% and 65%, respectively.

Example 3

Instead of dipping twice, a single layer of rubber gloves was prepared in the same manner as in Example 1 except that only 2nd dipping was carried out to prepare a rubber glove having a thickness of 70 mm, and the specimen of the KSM 6518 standard of Example 1 was prepared. The tensile load was measured using a result of 8.4kg / cm.

Example 4 and Comparative Example 2

Rubber gloves were prepared in the same manner as in Example 3, except that the amounts of chitosan or chitosan solution and seaweed powder or extracts thereof were 0.5wt% and 5wt%, respectively, and the tensile load was measured in the same manner as in Example 3. The results are shown in Table 2.

As can be seen from Table 1 and Table 2, the chitosan added to the rubber gloves has a deacetylation degree of 80% or more, and the antimicrobial effect is preferred, and the amount of chitosan or chitosan solution and seaweed powder or its extract is added to the raw material resin. In the case of more than 5wt% with respect to the liquid, the tensile load was remarkably dropped, which was less than the specification of KSM6633.

When manufacturing rubber gloves, 0.1 ~ 2wt% of chitosan or chitosan solution and seaweed powder or extracts thereof are added to the raw resin solution, and rubber gloves are manufactured to provide excellent antibacterial and cosmetic effects. This is good and there is an effect that the rubber gloves can be easily obtained without a decrease in strength.
