[0012]

In the dustproof garment of the present invention, an inner collar extending in the circumferential direction of the outer collar is provided inside the outer collar surrounding the wearer's neck, and this inner collar contacts the neck, so that the wearer's neck and outer wear can be made. The gap with the collar is closed by the inner collar, and the dust in the dustproof clothing is prevented from leaking from the base of the collar.

[0013] In the dustproof garment of the present invention, the outer collar is in the form of a stand collar, and the inner collar extends in the circumferential direction of the outer collar at the inner root of the outer collar and is provided so as to surround all or part of the neck. In such a configuration, the outer collar is hard to fall inward, which is preferable in appearance.

In the dustproof garment of the present invention, the inner collar has a hollow portion in the circumferential direction, a string is passed through the hollow portion, and both ends of the string are fixed to both ends of the inner collar in the circumferential direction or in the vicinity thereof. ,
In the form in which a part of this cord protrudes from the eyelet provided in the inner collar, by pulling the cord protruding from the eyelet, the length of the cord in the inner collar according to the neck circumference of the wearer is pulled. Can be adjusted.

[0015] A dustproof garment provided with a strap for stopping the movement of the string in the hollow portion of the inner collar, wherein the strap has elasticity, and one or more small holes having a diameter smaller than the diameter of the string are provided. It has two or more, and in the form in which the string passes through the small-diameter hole, it has the following action. The small diameter hole of the strap is smaller than the diameter of the string,
Since the strap is elastic, the strap is difficult to move due to frictional resistance in the small diameter hole. However, when the string is pulled with a force greater than the frictional force in the small diameter hole, the string moves while rubbing against the edge of the small diameter hole. Therefore, by pulling the string protruding from the eyelet hole, the string can be pulled out from the inner collar and the length of the string in the inner collar can be shortened. The length of the string in the collar can be adjusted. Also, if the pulling force of the string is reduced, the string becomes difficult to move again due to frictional resistance in the small diameter hole,
The string is difficult to return to the inner collar unexpectedly.

In the form having the dustproof hood covering the head and neck of the wearer, since the inner collar is in contact with the neck, dust from below the neck can be prevented from rising to the dustproof hood.

In the form in which the inner collar is made of a knit and the outer collar is made of a polyester fiber woven fabric, the inner collar has elasticity, so that even if the wearer bends the neck forward, backward, left and right, the inner collar is not bent. It is difficult to shift, and there is a low possibility that a gap is formed between the wearer's neck and the inner collar when the wearer bends the neck. In addition, since the knit of the inner collar easily absorbs the sweat of the wearer, discomfort due to sweat is reduced. Furthermore, since the polyester fiber woven fabric of the outer collar is less likely to generate dust, the outer collar is less likely to cause dust.
