Dust-resistant fabric having enhanced wearing sensations

The present invention relates to a dust-free fabric for producing dust-free garments for collecting dust in the working industry in the precision industry, such as semiconductor, precision machinery, medical field, more specifically, weaving dust-absorbing quick-drying and high shrink yarn The present invention relates to a dust-free fabric having improved wearing comfort.

Dust-free or dust-proof clothing is a special garment that is generally worn for the purpose of suppressing the contamination of the manufacturing site by dust or microorganisms generated from hair or skin at the production site of precision parts and the like. Conductive yarns are made using high density fabrics arranged in stripes or lattice to have an antistatic function. The conductive yarn refers to a yarn in which conductive carbon is mixed in a yarn manufacturing process to remove static electricity by using corona discharge.

In the semiconductor device manufacturing process, dust-free is essential. Recently, with the remarkable progress in the industrial field using the clean room, such as the integration of integrated circuits in the semiconductor industry, the cleanliness of the clean room is required to be higher. No-wear is being developed with a focus on maintaining and improving this cleanliness.

In order to prevent the dust generated, it is preferable to use a woven fabric made of synthetic fiber filament yarn rather than a dust-free woven yarn, and to prevent the dust generated in the human body and the inside of the worker from being penetrated out. Generally, high density method, calender processing method or coating method is used or these methods are used in combination.

In order to achieve the purpose of maintaining and improving the cleanliness as described above, Mujinjin uses a very high-density tissue fabric to prevent the outflow of fine contaminants generated in the human body. This is desirable from the viewpoint of cleanliness of the clean room, but in terms of comfort of the wearer, it creates an extremely uncomfortable environment.

Humans do not perceive sweating, but are constantly releasing moisture from the human body. This moisture dissipation is not perceived, so it is called "insensitive" (不 感 蒸 汗). Sweat caused by insensitivity is the standard body surface area of 1m², about 24g per hour, which is equivalent to about 900 ~ 1000g per day for adults with a body surface area of 1.6m². In the steady state, sweat is about 30% of the respiratory tract, about 70% through the skin, but the temperature and individual variations are known to be small. In general, the movement of water (evaporation) always involves the movement of heat, and because it causes a change in body temperature according to the change of external temperature, efficient control of sweat acts as a very important factor to keep the human comfort and body temperature constant. do.

Conventionally, despite the physical characteristics as described above, there was no consideration for people who work in dust-free clothes for the purpose of cleanliness of the clean room. However, dust-free clothing is a high-density tissue that is not breathable, causing a rise in temperature, and the wearer is exposed to a very unpleasant working environment, and the wearer is also a heating element (temperature rise above the body temperature), which acts as an obstacle to proper room temperature and humidity control. This leads to an increase in the defective rate of the product.

Therefore, recently, dust-free fabrics have been developed that improve the fit by improving absorbency and breathability without affecting the basic performance of the dust-free. However, the dust-free fabrics that have been improved so far have only a difference in the values of the test results to the extent that the breathable filter is installed or the absorbency is slightly increased. Development is urgent.

The present invention has been invented to solve the above problems, to improve the air permeability and absorbency of the dust-free fabrics inclined and weft yarn woven in a high density through a sectional cross-sectional sweat-absorbing quick-drying and high shrink yarn, moisture-free skin when absorbing moisture It is an object of the present invention to provide a dust-free garment having improved wearing feeling that can be worn and worked by a wearer who wears the dust-free garment by preventing it from sticking to it.

In order to achieve the above object, the present invention is a dust-free fabric in which the warp and weft yarn is formed of a high-density tissue, the warp and weft yarn is a continuous cross-section absorbing quick-drying yarn and high shrink yarn is continuously arranged at regular intervals The conductive yarn is inserted between the quick-drying yarn and the high shrink yarn, and provides a dust-free fabric with improved fit, characterized in that weaving in plain weave.

In addition, the release cross-section sweat-absorbent quick-drying yarn, high shrink yarn, the conductive yarn is characterized in that weaving at a weight ratio of 48 to 82% by weight of the cross-sectional sweat absorption quick-drying yarn, 15 to 46% by weight of the high shrink yarn, 3 to 7% by weight of the conductive yarn. Provides dust-free fabric with improved fit.

In addition, the release cross-sectional sweat-absorbent quick-drying provides a dust-free fabric for improved comfort, characterized in that the antimicrobial treated antibacterial yarn.

In addition, the release cross-section of the quick-drying sweat-absorbing quick-drying provides a dust-free fabric for improved comfort, characterized in that the cross-section.

In addition, the high shrink yarn provides a dust-free fabric with improved comfort, characterized in that the two-ply yarn.
