Description

FIELD OF THE INVENTION

The present invention relates to medical gloves and to a method as a manufacturing process for the production of powder-free latex gloves from synthetic and natural rubber by immersion, and to methods and materials used in the manufacture of such gloves. Especially this invention relates to medical gloves made of synthetic and natural latex and to other products from latex, in the production of which powder-free coagulant is used.

BACKGROUND OF THE INVENTION

Gloves made from elastomeric materials such as natural rubber latex and synthetic latex have a number of problems. An important criterion for medical gloves is that they must fit snugly on the hands of the person they are wearing. Natural rubber with its characteristic high coefficient of friction makes donning gloves difficult. To solve this problem, conventional medical gloves are used with a lubricant on the inner surface to facilitate putting on gloves. This grease also serves to facilitate the removal of gloves from the hand-shaped template used in production. Usually the grease is in the form of a powder and, as a rule, has the nature of an absorber; for example, starch powder is usually used. However, doctors have doubts about the use of loose dusting agent (powder) in gloves used in surgical interventions. As a result, much effort has been made to reduce or eliminate the use of loose powder to facilitate putting on medical gloves by developing various powder-free methods to improve donning performance.

Synthetic latex and natural rubber gloves are usually produced by immersing a template in the shape of a hand or mandrel, first in a bath with powdered coagulant, then immersing the template in a bath with latex or natural rubber and refinement using leaching and drying processes. Often gloves made in this way result in products that tend to adhere to the template after drying. When removed from the template, gloves made in this way often tear and stick together.

For industrially manufactured gloves, the coagulant bath includes a mineral powder to provide release properties on the surface of the template. Release powders prevent two layers of gloves from sticking to each other. Typically, the powder is calcium carbonate or talc, as these powders can withstand the high temperatures (100-130 ° C) used in the manufacture of latex gloves. On the outside, a layer of starch or other powder is applied by immersing the cured latex glove template in a starch suspension bath. Alternatively, cured latex gloves may be coated with a synthetic polymer layer to impart anti-adhesive properties.

There is also information related to the processes of chlorination, rinsing and silicification for the manufacture of powder-free medical gloves offline. These processes remove residual talc and corn starch powder, reduce stickiness and improve glove wear. However, these processes are usually laborious and require large amounts of water, making them very expensive. In addition, chlorination can lead to poor strength, discoloration, and poor aging performance of gloves. In some cases, chlorination can be a hazard to storage and to the environment.

The manufacture of powder-free medical gloves using the chlorination process, polymer coating methods, or a combination thereof is disclosed in US Patent No.6195805; 5,674,818; 5612083; 5,570,475; 5,284,607; 5,088,125; 4597108 and 4143109. However, there are several sources describing the manufacture of powderless gloves without subsequent (or offline) process steps, such as chlorination, washing and / or silicification. These several sources include US Patent No. 6075081; 5534350 and 4310928.

US Patent No. 6075081 (Nile) discloses a powderless coagulant for use in latex immersion processes, containing a dispersion of polychloroprene rubber and an inorganic metal salt that is stable to the action of salts. The coagulant of this source may also contain a powder-free mold release agent containing an emulsion of polypropylene wax and a cationic surfactant in order to facilitate separation of the dipped article from the template.

US Patent No. 5534350 (Liou) discloses a method as a process for manufacturing powderless medical gloves in an on-line mode using a polyurethane polymer in a coagulant that acts as a waterproof (water repellent) lubricating layer to facilitate removal of a glove from a ceramic template. A layer of polyurethane polymer on the inside of the glove improves donning.

US Patent No. 4310928 (Joung) discloses a glove template for coating with a coagulant containing a lipo compound and a surfactant in suspension. These materials remain on the glove after removing it from the template, thereby providing a free (non-adherent) surface for the glove.

In addition, US Patent No. 6378137 (Hassan et al.) Discloses the manufacture of powderless medical gloves, in which a release composition of a polymer or copolymer mixed with a finely divided material from high density polyethylene and wax is used. This composition facilitates putting on gloves. However, in the final product, the glove is mainly powder-free and requires autonomous treatment with a mixture of silicone emulsion and wax. US Patent No. 6019922 (Hassan et al.) Discloses an additional method of manufacturing powderless medical gloves, which includes silicone treatment from the outer surface of the glove and an anti-adhesive composition from the inner surface of the glove. The release composition of this link is composed of a polymer or copolymer, a finely divided material of high density polyethylene and wax. However, in order to produce the gloves of this reference, the manufacturer must rinse the final glove in order to remove the remaining coagulant powder. This washing process is not perfect and results in gloves that are more likely to be mostly powder-free rather than completely powder-free. The manufacturing process of the gloves of this disclosure also requires an offline process, including processing the gloves with silicone solution to obtain the final product.

Therefore, it is desirable to have a powder-free, non-sticky (non-sticky) glove with good donning characteristics that can be easily removed from the glove template after manufacture. It is also desirable that such a powder-free glove requires only a minimum number of process steps, most preferably the requirement of a flow regime of the process. Therefore, it is desirable to provide a new method for the manufacture of powder-free dipped gloves from synthetic latex or natural rubber, which will solve the above problems of the technological process in an autonomous mode. Embodiments of the present invention provide a new coagulant composition that eliminates the offline process because calcium carbonate is not used, and as a result, offline chlorination, washing and silicification are eliminated. The resulting process reduces production costs and gives a completely powder-free glove.

Summary of the invention

In accordance with one embodiment of the present invention, the powderless coagulant composition is used with synthetic polychloroprene latex in an in-line process for making gloves that are powderless and do not require an offline process. In particular, the process used to make these gloves, in one embodiment, involves immersing the hand-shaped template in a new coagulant composition containing micronized high density polyethylene, an aminosilicon microemulsion, a dimethicone emulsion (1,1,1,3,3, 3-hexamethyldisiloxane), calcium salts, surfactant and cellulosic thickener, before immersing the template in a composition of natural rubber or synthetic latex.

In one embodiment, the manufacturing method of an article of the present invention includes the steps of: immersing a pre-heated template in a specific shape in an aqueous powdery solution containing an aqueous solution of finely divided high density polyethylene, salt stable, an aminosilicon microemulsion, dimethicone emulsion, a surfactant on based on acetylene diol and inorganic metal salt; immersing the template in a dispersion of polychloroprene latex to form a gel-like latex film and to create a non-stick surface in the product; leaching a gel-like latex film; priming a gel-like latex film with a low salt solution; immersion of a gel-like latex film in a solution for applying a polymer layer (coating); drying the polymer coating; curing the formed rubber products on the template and removing the cured non-stick product from the template.

The polymer coating on the inside of the glove can be acrylic or polyurethane based and can be applied before curing. Such a coating can be further improved by immersing the cured glove in a silicone impregnating composition before removing the glove from the template. Such an optional silicone-impregnated polymer coating will serve to facilitate donning of the glove.

In accordance with the principles of this invention, there is provided a method for manufacturing powderless rubber or latex products, in particular products manufactured using standard immersion processes such as medical and surgical gloves, condoms and catheters.

The drawing illustrates a flowchart of an immersion process method for manufacturing in-line powderless gloves in accordance with one embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention provide the ability to change the setting characteristics of a product made of synthetic latex or natural rubber, especially a medical glove, in accordance with the compositional amount of the dimethicone emulsion introduced into the new coagulant composition. In one embodiment, the new coagulant composition at the end of the manufacturing process will be on the outer surface of the glove, creating a slippery surface that will improve the ability to double-wear gloves or wear two pairs of gloves, one on top of the other. The indicated “grip characteristics” are both qualitative and quantitative characteristics that determine the “slippiness”, or coefficient of friction, of the surface of the resulting glove. In particular, the quality characteristics include a slippery feeling during tactile contact with a finger on a gloved hand; the clearer the contact, the stronger the grip on the surface of the glove, and vice versa. By quantitative characteristics of setting, is meant the value of the coefficient of friction; the lower the coefficient of friction, the weaker the grip between the glove and the held surface (a more slippery surface), and vice versa. The friction coefficient is the ratio of the force applied in the transverse direction to the force applied normal to the surface.

According to Table 1, “gram-force” means the force exerted in the transverse direction necessary to shift one material relative to another.

The constant force developed by the test device is a “normal force”, as is obvious to a person skilled in the art.

Products, in particular medical gloves manufactured in accordance with embodiments of the present invention, are formed by immersing a heated hand-shaped pattern (smooth, patterned or textured) in a new coagulant composition. The new coagulant composition includes micronized high-density polyethylene, an aminosilicon microemulsion, a dimethicone emulsion, calcium salts, an ethoxylated acetylene diol surfactant and a cellulosic thickener. The coagulant-coated template is then removed from the coagulant tank and immersed in a synthetic or natural elastomeric latex dispersion to form a gel-like latex film. Preferably, the latex is polychloroprene latex. Then the gel-like latex film is leached and immersed in a polymer coating solution.

In accordance with one embodiment of the present invention, the gelled latex gloves are then cured on the template before removing the cured non-stick product from the template. In another embodiment of the present invention, gelled latex gloves are cured on the template and then immersed in a silicone impregnating composition before removing the gloves from the template. The silicone-coated polymer coating described in this embodiment of the invention will further facilitate donning of the glove.

Preferably, a dimethicone-based silicone emulsion is prepared from a polydimethylsiloxane liquid having a viscosity ranging from about 10,000 to about 100,000 centistokes at 25 ° C and an average molecular weight of from about 62700 to about 116500.

Emulsions obtained from dimethicone liquids within the above range of viscosities, when coagulant is introduced into a new composition, will provide a relatively small viscosity deviation in a wide temperature range. Emulsions will provide good heat and oxidation resistance, chemical inertness and fracture resistance during mechanical shear. They will also impart good antifriction properties to the elastomeric surface of the glove that is exposed in contact with the new coagulant, making it easier to remove gloves from the patterns during production.

Some emulsions and liquids (solutions) obtained from dimethicone liquids are commercially available. For example, an emulsion obtained from a dimethicone liquid with a viscosity of approximately 10,000 centistokes is sold by GE Silicones, USA, under the trade name SM 2140. A liquid obtained from the same basic substances, is sold by GE Silicones, USA, sold under the trade name VISCASIL 10M. An emulsion obtained from dimethicone liquid with a viscosity of approximately 100,000 centistokes is sold by GE Toshiba Silicones Co. Ltd, Japan, under the trade name XS65-135891. Fluid derived from the same basic substances, GE Toshiba Silicones Co. Ltd, Japan, sells under the trade name TSF 451-10M. Dimethicone fluids with viscosities ranging from about 10,000 to about 100,000 centistokes are classified as high viscosity fluids and sold under the trade name 200 FLUID (Dow Corning Corporation). Emulsions can also be obtained from a mixture of dimethicone and cyclomethicone; an example of such an emulsion is sold by Dow Corning Corporation under the trade name DOW CORNING Q2-1803.

The use of aminosilicon microemulsions is designed to obtain a silky texture on the surface of the glove and enhance the softness of the gloves. An aminosilicone microemulsion comprising heterogeneous particles having a size of from about 1 to about 100 microns is commercially available under the trade name SOFTEX 5850 sold by Kao Industrial (Thailand) Company Ltd.

The use of finely divided high density polyethylene can act as a fixative to improve the hiding power of the coagulant film, as well as to facilitate the removal of gloves from hand-shaped templates. Fine-grained high-density polyethylene also provides (gives) anti-friction and anti-adhesive properties of the outer surface of the glove (the side of the glove in contact with the coagulant during the immersion process). The effective melting temperature range for high density polyethylene is typically from about 100 to about 130 ° C. The average particle size of the finely divided high density polyethylene is typically from about 3 to about 12 microns.

Acetylene diol-based nonionic surfactant is usually used as a humectant (wetting agent) for the coagulant, and coagulant is preferred to thicken with a cellulose thickener.

Embodiments of the present invention will now be described more fully in the following examples and accompanied by a flowchart of a method for manufacturing such products (see drawing) in accordance with embodiments of the invention.

EXAMPLE 1

The ceramic biscuit firing pattern was heated to 60-70 ° C and then immersed in a dispersion of anti-adhesive coagulant with a temperature of 25-35 ° C for about 5-10 seconds. Coagulant dispersion contained:

the weight.% Calcium nitrate eighteen% Fine Density Polyethylene (HDPE) one% Aminosilicone microemulsion one% Cellulose thickener 0.2% Acetylene Diol Surfactant 0.3% Water 79.5%

In the preparation of the composition of Example 1, finely divided high density polyethylene (HDPE) was added as a 20% dispersion, an aminosilicon microemulsion was applied as a 20-22% emulsion, a cellulosic thickener was diluted to a 1% solution, and an acetylene diol surfactant was added as as received. After immersion in the coagulant dispersion, the ceramic template was slowly pulled out of the coagulant dispersion and rotated to uniformly distribute the coagulant over the surface of the template. The template was then transferred to an oven heated to 90 ° C for approximately 90 seconds to dry the coagulant. After drying, the ceramic pattern was immersed in a dispersion of polychloroprene latex for approximately 20-30 seconds. This dispersion of polychloroprene latex contained 40% dry polymer, and its temperature was maintained at 25 ° C. After applying the polychloroprene latex to the template, it was turned upside down and raised and then heated in an oven at 75 ° C for approximately 60 seconds. The gelled polychloroprene latex was then leached at a temperature of 40 to 60 ° C. for approximately 180 seconds. A polychloroprene polymer gel on a ceramic template was then immersed in a primer solution with 1-2% salts before immersion in a solution for applying either a polyurethane or acrylic coating. Then the ceramic template was gradually dried at a temperature of from 110 ° C to 140 ° C for 35 minutes. Then, before removing the gloves from the template, it was cooled. The template can be reused in further production cycles by washing it in acid and then in water. The template can also be easily cleaned with standard detergents used in immersion gloves.

The glove, which was made by immersion using the powder-free composition of the coagulant of Example 1, was without thin sections and was easily removed from the ceramic template. Grasping of the glove was satisfactory, and double putting on the gloves was satisfactory for the same type and size of gloves. A polychloroprene glove shows signs of a powderless product with a powder content of less than 2 mg per glove.

EXAMPLE 2

In accordance with Example 1, the gloves were made according to the same process scheme with the exception of the composition of the anti-adhesive coagulant. The dispersion of the anti-adhesive coagulant for this example contained:

the weight.% Calcium nitrate eighteen% Fine Density Polyethylene (HDPE) one% Aminosilicone microemulsion one% Dimethicone / Cyclomethicone Emulsion 0.1% Cellulose thickener 0.2% Acetylene Diol Surfactant 0.3% Water 79.4%

In this example, the added emulsion of a mixture of dimethicone and cyclomethicone was supplied as a 60% emulsion. The dipped gloves produced in this example were made well, without thin patches and were easily removed from the ceramic template. Grasping the glove was less intense than for the glove produced in Example 1, and double putting on the gloves was good when using the same type and size of gloves. A polychloroprene glove shows signs of a powderless product with a powder content of less than 2 mg per glove.

EXAMPLE 3

In accordance with Example 1, the gloves were made according to the same process scheme with the exception of the composition of the anti-adhesive coagulant. The dispersion of the anti-adhesive coagulant for this example contained:

the weight.% Calcium nitrate eighteen% Fine Density Polyethylene (HDPE) one% Aminosilicone microemulsion one% Dimethicone / cyclomethicone emulsion (100,000 centistokes) 0.1% Cellulose thickener 0.2% Acetylene Diol Surfactant 0.3% Water 79.4%

In this example, the supplied emulsion of a mixture of dimethicone and cyclomethicone was industrially produced from a polydimethylsiloxane liquid with a viscosity of 100,000 centistokes, measured at 25 ° C. The dipped gloves were made well, without thin sections and were easily removed from the ceramic template. The grip of the glove was more slippery than for any glove of the previous examples 1-2, and double putting on the gloves was excellent when using the same type and size of gloves. A polychloroprene glove shows signs of a powderless product with a powder content of less than 2 mg per glove.

EXAMPLE 4

In accordance with Example 1, the gloves were made according to the same process scheme with the exception of the composition of the anti-adhesive coagulant. The dispersion of the anti-adhesive coagulant for this example contained:

% the weight.% Calcium nitrate eighteen% Fine Density Polyethylene (HDPE) one% Aminosilicone microemulsion 2% Dimethicone emulsion (10,000 centistokes) 0.2% Cellulose thickener 0.2% Acetylene Diol Surfactant 0.3% Water 78.3%

In this example, the supplied dimethicone emulsion was industrially produced from a polydimethylsiloxane fluid with a viscosity of 10,000 centistokes measured at 25 ° C. The dipped gloves were made well, without thin sections and were easily removed from the ceramic template. The grasping of the gloves was less slippery than the grasping of the gloves produced in Example 3, and less intense than the grasping of the gloves in Examples 1 and 2. Double putting on gloves of the same size and type was excellent. A polychloroprene glove shows signs of a powderless product with a powder content of less than 2 mg per glove.

Assessment of gloves made according to examples 1-4 was carried out at a qualitative level.

EXAMPLE 5

In accordance with Example 1, the gloves were made according to the same process scheme with the exception of the composition of the anti-adhesive coagulant. The dispersion of the anti-adhesive coagulant for this example contained:

the weight.% Calcium nitrate eighteen% Fine Density Polyethylene (HDPE) one% Aminosilicone microemulsion 2% Dimethicone emulsion (10,000 centistokes) 0% Cellulose thickener 0.2% Acetylene Diol Surfactant 0.3% Water 78.5%

EXAMPLE 6

In accordance with Example 1, the gloves were made according to the same process scheme with the exception of the composition of the anti-adhesive coagulant. The dispersion of the anti-adhesive coagulant for this example contained:

the weight.% Calcium nitrate eighteen% Fine Density Polyethylene (HDPE) one% Aminosilicone microemulsion 2% Dimethicone emulsion (10,000 centistokes) 0.2% Cellulose thickener 0.2% Acetylene Diol Surfactant 0.3% Water 78.3%

EXAMPLE 7

In accordance with Example 1, the gloves were made according to the same process scheme with the exception of the composition of the anti-adhesive coagulant. The dispersion of the anti-adhesive coagulant for this example contained:

the weight.% Calcium nitrate eighteen% Fine Density Polyethylene (HDPE) one% Aminosilicone microemulsion 2% Dimethicone emulsion (10,000 centistokes) 0.4% Cellulose thickener 0.2% Acetylene Diol Surfactant 0.3% Water 78.1%

The setting characteristics obtained using the different dimethicone content in Examples 5-7 are summarized in Table 1. The setting properties were determined on a friction coefficient measuring device manufactured by RJ Harvey Instrument Corporation, USA.

Table 1 Frictional characteristics of rubber measured on the coagulant side Dimethicone content Example 5 Example 6 Example 7 0% Dimethicone 0.2% Dimethicone 0.4% Dimethicone Gram power (gf) Coefficient of friction (CT) Gram power (gf) Coefficient of friction (CT) Gram power (gf) Coefficient of friction (CT) Metal by

As can be seen from Table 1, by varying the content of dimethicone in the coagulant, it is possible to change the frictional characteristics of the surface of polychloroprene rubber on the side with the coagulant in accordance with the requirements for the setting characteristics. All polychloroprene gloves in Examples 5-7 have signs of powderless products with a powder content of less than 2 mg per glove.

EXAMPLE 8

In accordance with Example 1, the gloves were made according to the same process scheme with the exception of the composition of the anti-adhesive coagulant and when replacing the dispersion of the polychloroprene latex of Example 1 with natural rubber latex. The dispersion of the anti-adhesive coagulant for this example was identical to the dispersion used in Example 4.

The dipped gloves made of natural rubber were well made, without thin sections and were easily removed from the ceramic template. The grasping of the glove was more intense than the grasping of any of the gloves of Examples 1-7. The frictional characteristics of rubber (rubber), measured using the RJ Harvey, show the value of the gram force in the case of friction of metal on rubber (MR) of approximately 250 g, which correlates with a coefficient of friction of 1.26. A natural rubber glove shows signs of a powder-free product with a powder content of less than 2 mg per glove.

EXAMPLE 9

The manufacturing process of the coagulant and the manufacture of gloves was identical to the manufacturing process in Example 8 with the exception of the coagulant composition. The dispersion of the anti-adhesive coagulant for this example contained:

the weight.% Calcium nitrate eighteen% Fine Density Polyethylene (HDPE) 2.5% Aminosilicone microemulsion 2.5% Dimethicone emulsion (or 10,000 or 100,000 centistokes) 0.4% Cellulose thickener 0.2% Acetylene Diol Surfactant 0.3% Water 76.1%

Dipped gloves made of natural rubber, made using the composition of this example, were made well, without thin sections and were easily removed from the ceramic template. The grasping of the glove was less intense than the grasping observed for gloves made using the composition of Example 7. Double putting on gloves of the same size and type was satisfactory. The frictional characteristics of the rubber, measured on an RJ Harvey, show an MR value of approximately 135 gf or a coefficient of friction (CT) of 0.68. The natural rubber gloves of this example show signs of powder-free products with a powder content of less than 2 mg per glove.

Thus, the authors intend to include all such alternatives, modifications and changes related to the essence and comprehensive scope of the attached claims.
