Description

Industrial glove having antistatic property and frame retardance

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to industrial gloves having antistatic properties and flame retardancy. The present invention relates to industrial gloves having a thinner thickness and a better fit than conventional industrial gloves.

Static electricity generated in various kinds of precision workshops is a deadly factor, and static electricity is a very important management factor in semiconductor manufacturing sites such as integrated circuits that require high precision, assembly sites of ultra-precision devices, and manufacturing of active and passive devices. It is becoming.

Particularly in the case of semiconductor manufacturing field such as integrated circuit manufacturing, the accumulated static electricity between worker's body or component material causes instantaneous high power discharge between worker's hand and parts when worker's hand contacts parts. Cauterization of the circuit causes problems such as causing defects or increasing surface resistance.

Therefore, in such a conventional work site, gloves having an antistatic function having the property of removing static electricity are widely used.

Patent documents 1 and 2 have been proposed in relation to gloves having an antistatic function.

Patent Literature 1 relates to a work glove having an antistatic function, wherein a conductive yarn made of copper conductive yarn or carbon yarn is braided to form an antistatic work unit to secure antistatic properties and to coat a resin such as polyurethane. Antistatic property can be secured by the conductive yarn, but it is not suitable for an industrial environment in which flame retardancy is required because of poor flame retardancy.

In addition, Patent Document 2 relates to an electrostatic removing glove, and secures an antistatic property by providing a conductive portion formed by alternately communicating the Sotomote surface and the inner surface of the long dough of the zippore portion with the conductive chamber. However, since the outer surface is made of synthetic leather, the flame retardancy is not good, and there is an inappropriate problem in an industrial environment in which the flame retardancy is to be secured.

1. Publication No. 2005-0052435. 2. Japanese Patent Laid-Open No. 2006-063456.

The present invention for solving the conventional problems as described above has an object to provide an industrial glove with a thin thickness and excellent wearing comfort, excellent antistatic and flame retardant compared to the conventional industrial gloves.

According to an aspect of the present invention,

It provides an industrial glove with antistatic and flame retardant, characterized in that it comprises a fabric woven in a blended yarn formed by blending 25 ~ 150 parts by weight of Tencel flame retardant yarn to 100 parts by weight of flame resistant fiber.

In the blended yarn, it is preferable that carbon fibers are mixed, and in particular, the carbon fiber is preferably blended 10 to 30 parts by weight with respect to 100 parts by weight of the flame resistant fiber.

In addition, the fabric is composed of the outer shell of the glove, the inner shell of the glove is preferably made of aramid fibers.

And it is preferable that the outer shell and the inner shell are formed by weaving the blend yarn and the aramid fibers in a double woven fabric.

Hereinafter, the industrial gloves having antistatic properties and flame retardancy of the present invention will be described in detail.

Industrial gloves having antistatic properties and flame retardancy of the present invention comprises a fabric woven in a blended yarn formed by mixing 25 to 150 parts by weight of tencel flame retardant yarn to 100 parts by weight of flame resistant fiber.

The chlorinated fibers are preferably chlorinated fibers obtained by treating the carbon fiber precursor in an oxidizing atmosphere at 200 to 300 ° C. By treating the carbon fiber precursor in an oxidizing atmosphere at 200 to 300 ° C., excellent flame retardant effect can be obtained without using a flame retardant made of an inorganic substance.

Particularly, in order to obtain excellent flame retardancy and flammability, the carbon fibers precursor is preferably treated in an oxidizing atmosphere at a temperature of 200 ° C to 220 ° C and a temperature of 290 ° C to 300 ° C at an elevated temperature of 5 ° C to 6 ° C / minute.

As the carbon fiber precursor, a precursor such as a polyacrylonitrile (PAN), a pitch, or a rayon may be used.

In addition, the Tencel flame retardant yarn is an eco-friendly cellulose-based regenerated fiber extracted from natural pulp, and has non-halogen flame retardant added to the tencel, thereby retaining eco-friendly and permanent flame retardancy. , Breathable and soft touch.

As the tencel flame retardant yarn, it is common to use tencel flame retardant yarn developed and released by Lenzing.

The tencel flame retardant yarn is mixed 25 to 150 parts by weight to 100 parts by weight of the flame resistant fiber. If less than 25 parts by weight, the physical properties such as spinning, dyeing, strength, etc. is not good, if more than 150 parts by weight, there is a problem of weak flame deterioration and poor antistatic properties.

In particular, the fabric is preferably used to weave a blended yarn blended with carbon fibers to improve the antistatic properties. The carbon fiber is preferably blended 10 to 30 parts by weight based on 100 parts by weight of the flame resistant fiber. When the carbon fiber is blended to less than 10 parts by weight, the antistatic properties are not greatly improved. If the carbon fiber is blended to more than 30 parts by weight, manufacturing costs increase and trimming occurs frequently during the spinning process.

The blended yarn is manufactured through a blending process, a carding process, a softening process, a spinning process, and a spinning process that are generally used during blending. On the other hand, the chlorinated fiber, tencel flame retardant yarn and carbon fiber that is introduced into the blending surface process is preferably used is cut into a fiber length of 35 ~ 60mm. If the fiber length is less than 35mm, physical properties such as spinning and strength are not good, and if the fiber length is more than 60mm, a uniform wrap may not be obtained and fibers may be entangled during the carding process.

Industrial gloves made of such a blend of woven fabric has the advantage of excellent antistatic properties and flame retardant.

In particular, the fabric woven in the blended yarn constitutes the outer shell of the industrial glove, the inner shell is preferably composed of aramid fibers. Since the fabric woven from the blended yarn having excellent antistatic properties and flame retardancy is composed of an outer shell, it can be widely used not only in the semiconductor field but also in industrial sites with heat such as welding, and furthermore, since the outer shell is made of aramid fibers, it has excellent durability such as strength. Do.

In addition, the blended yarn and the aramid fibers are woven in a double weave using a jacquard loom or the like to form the shell and the endothelium.

Industrial gloves of the present invention is thinner than the conventional industrial gloves, excellent in wearing comfort, excellent in antistatic properties and flame retardant, there is an effect that can be widely used in industrial sites with heat such as welding as well as semiconductor factories.

Hereinafter, the industrial gloves having antistatic properties and flame retardancy of the present invention will be described in detail with reference to Examples. The scope of the present invention is not limited to the following Examples.
