Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to moisture permeable gloves. More specifically, among disposable gloves made of resin, the gloves are moisture-permeable and can prevent moisture from getting inside without allowing water to pass through when worn.

<Problem to be solved by the invention> Disposable gloves conventionally used for business and home use are mainly made of resin films such as polyethylene, and the area between the hand and the glove gets stuffy, making it uncomfortable to wear. Moreover, it was difficult to wear it for a long time.

An object of the present invention is to provide moisture-permeable gloves that cause very little stuffiness even when worn and can be worn for a long time.

<Means for Solving the Problems> The present inventors have continued to conduct intensive research on gloves that prevent the gloves from getting stuffy. As a result, it was discovered that by making part or all of the glove a soft film with a certain moisture permeability, a glove that does not get stuffy can be obtained, leading to the present invention.

That is, in the present invention, the median pore diameter is 100 Brn or less, and JIS ZO2081!11-4 (1'C
Moisture permeability at 00% RII is 1000-150 ('1
These are moisture-permeable gloves made of a film with a weight of 0 g/m, ・day.

The moisture permeability of the moisture permeable film l used in the present invention is 1000~
15000g/m-aay, preferably 40
(111 to 15 (100 g/m-day).

If the moisture permeability is l(')00H/m -clay without grooves, it is not preferable because it does not have a remarkable effect on the internal moisture of the glove, and it is 15000g/m''・(l a y
If it exceeds , the strength of the film decreases, which is not preferable.

In the present invention, the pores for imparting moisture permeability need to have a median pore diameter of 100 μm or less. The median pore diameter is the median pore diameter by volume as measured by mercury porosimetry. If the central pore diameter exceeds 100 μm, when it comes into contact with a liquid, the liquid may penetrate into the glove through the pores, resulting in the glove's performance as a glove in terms of hygiene and protection. For example, a film made of a resin and a filler may be stretched to generate fine pores in the film to prevent 3α bodies such as water from forming. The solution is to use a moisture-permeable film that does not allow water vapor and air to pass through.

Examples of resins for moisture-permeable FILNO include low-density polyethylene, high-density polyethylene, boria [I-pyrene,
α-olefin homopolymers such as polybutene, copolymers of ethylene and at least one α-olefin having 3 to 18 carbon atoms, Jli combinations of propylene and ethylene and/or butene-1, ethylene and vinyl acetate and/or
Alternatively, copolymers of late acrylic esters, Nisder methacrylates, and N-carboxylic acid derivatives having an ethylenically unsaturated bond may be mentioned.

Examples of fillers include calcium blown acid and magnesyl carbonate.
1. Carbonates such as barium carbonate, sulfates such as barium sulfate, magnesyl sulfate, calcium sulfate, magnesium phosphate, phosphorus 11, hydroxides such as magnesium hydroxide, aluminum hydroxide, etc. Oxides such as alumina, silica, magnesium oxide, zinc oxide, titanium oxide, zinc chloride
Chlorides such as iron chloride, arsenic salt, aluminum, powder, zeolite, shirasu, white clay, diatomaceous earth, talc, carbon black, volcanic ash (without fillers or wood), cellulose powder such as bulb powder, Synthetic resin powders such as nylon powder, polycarbonate powder, Boria a-pyrene powder, poly-4-methylpentene-1 powder, telephone)
These may be used alone or in combination. Calcium carbonate is particularly preferred from the viewpoint of moisture permeability, flexibility, appearance, etc. of the film. The average particle size of the filler is preferably from 0.1 to 20 linl from the viewpoint of uniformity of the film due to filler dispersion and the median pore diameter after stretching, and in particular 0.8 to 5.0 μm is preferable for the film. Preferable from the viewpoint of strength.

In addition, from the viewpoint of processability and film strength, the blending ratio of these fillers is 40 to 40
, 100 parts by weight, preferably 80 to 300 parts by weight.

The moisture-permeable film 1 in the present invention is a roll-type or Banbury-type film containing a resin, a filler, and, if necessary, a dispersant and a stabilizer. A composition is obtained by mixing or kneading in a conventional manner using a U-kneader or single-screw or twin-screw extrusion. Then, inflation processing from the two OMl compositions,
The film is manufactured by conventional film forming methods such as calendering and T'/l' processing. Next, this film is stretched to give it moisture permeability.
The stretching is carried out uniaxially or biaxially. - For the 11th axial stretching, roll stretching is usually preferred;
It is also possible to use tubular drawing to emphasize the take-up direction, or a method in which a mandrel is installed inside the film during inflation processing. In the case of biaxial stretching, simultaneous biaxial stretching is possible, or sequential biaxial stretching in which stretching is performed in the longitudinal direction and then in the transverse direction is also possible.

The moisture-permeable glove of the present invention requires a portion or all of the glove to be made of a moisture-permeable film. Moisture-permeable gloves can be obtained, for example, by stacking two moisture-permeable films or one moisture-permeable film and one resin film, heat-sealing them in the shape of a hand, and then cutting the outer periphery.

<Effects of the Invention> The moisture-permeable gloves of the present invention prevent internal stuffiness when worn and can be used comfortably for long periods of time, and are not only water and chemical resistant, but also have excellent flexibility and stretch. Therefore, it has good workability and is ideal as a disposable glove.
