塵埃通過阻止性が不充分となる。(Prior Art) Dust-free gloves used in clean rooms are required to have properties that prevent dust from passing through and do not generate dust, so gloves made of films such as polyethylene, vinyl chloride, or rubber have conventionally been used. However, since these gloves have no breathability, they tend to get stuffy when worn and have poor workability. On the other hand, knitting,
Gloves made of fabric or the like have breathability, but fibers may fall off from the cut end, making them unsuitable as dust-free gloves. On the other hand, Japanese Utility Model Application Publication No. 60-52910 proposes anti-slip gloves made of polyurethane nonwoven fabric. This glove satisfies the requirements of both breathability and dust-free properties. However, when the polyurethane nonwoven fabric is made thin, this glove becomes insufficient in preventing dust from passing through.

目的とする。(Problems to be solved by the invention) The invention has properties that prevent dust from passing through, does not generate dust, and has breathability, so it does not get stuffy when worn.
Furthermore, the objective is to provide dust-free gloves that are easy to wear because they have elasticity.

This relates to a glove that is made by stacking the gloves so that the gloves are stacked one on top of the other, and the peripheral edge of the glove shape is fused and joined.

行ない後に開口部を裁断することが好適である。 In order to obtain the gloves of the present invention, for example, two stretchable sheets made by laminating a polyurethane film on a polyurethane nonwoven fabric are stacked one on top of the other, with the polyurethane nonwoven fabric on the inside, and a high-frequency welder mold equipped with a glove-shaped mold is used. It is preferable to heat the portion, perform cutting by melting and joining by fusion at the same time, and then cut the opening.

The filament is discharged from a spinning nozzle using the spinning apparatus described in the above publication, and the filament is thinned by a heated gas flow ejected from both sides of the nozzle, for example. The attenuated filaments are separated from the gas stream and deposited on an auxiliary device, such as a moving conveyor net, without being substantially focused. The stacked filaments are bonded together at their contact points by the filaments themselves in a stacked state due to their own heat. They may be bonded by heating and pressing using a roller or the like before or after cooling and solidifying after being laminated on the collection device.

湿性の点から特に乾式法、湿式法が好適である。 The polyurethane film used in the present invention can be obtained by a known film forming method such as a melting method, a dry method, or a wet method. From the viewpoint of stretchability and moisture permeability of the obtained film, dry methods and wet methods are particularly suitable.
乾式製膜法による乾式フイルムはたとえば溶剤

A preferred method is to coagulate and regenerate polyurethane by immersing it in water.

It is desirable that the heating time be at least 24 hours, preferably at least 2000 g/m 2 /24 hours. (Measurement method: JIS20208, temperature
(40℃, humidity 90% RH, measurement time, 4 hours) If the moisture permeability is low, gloves will tend to get stuffy when worn.

On the other hand, the drawbacks of polyurethane film, such as low strength, stickiness, and difficulty in handling, have been overcome. Therefore, the gloves of the present invention are breathable and stretchable, making them easy to wear and suitable for work and exercise, and also extremely useful as dust-free gloves for clean rooms.
