Description

High-strength, cut-resistant, and heat-resistant fabric The present invention relates to a high-strength, cut-resistant, and heat-resistant fabric. Work safety gloves are broadly classified into welding gloves, heat-resistant gloves, cut-resistant gloves, and chemical-resistant gloves. Heat-resistant gloves protect a worker's hands from high temperatures, cut-resistant gloves protect hands from sharp objects in the workplace, and chemical-resistant gloves protect hands from chemical substances. These conventional work gloves are stipulated not to be worn when handling machinery where there is a risk of fingers getting caught, such as presses that compress workpieces with high pressure or devices that process workpieces through rotational motion. This is because there is a risk that a worker's hand may get caught in the machinery due to user negligence or malfunction when handling such equipment. If work gloves are worn on the hands, even if only the finger portions of the gloves get slightly caught, the gloves prevent the hand from being pulled out of the machinery, causing the entire hand or, in severe cases, even the arm to get caught, thereby causing a much more serious safety accident. Heat-resistant and cut-resistant gloves for protecting workers' hands in industrial settings have been proposed, such as in Patent Document 0001. Patent document 0001 relates to a heat-resistant work glove having both heat resistance and cut resistance, wherein the glove portion is constructed by weaving a first mixed yarn with excellent heat resistance and cut resistance and a second mixed yarn with excellent elasticity and wearability, such that the first mixed yarn forms the outer layer and the second mixed yarn forms the inner layer, thereby possessing both heat resistance and cut resistance simultaneously, allowing it to be safely used in workplaces requiring heat resistance as well as workplaces requiring cut resistance, and also improving wearability to enhance workability. The high-strength, cut-resistant, and heat-resistant fabric of the present invention will be described in detail below. The high-strength, cut-resistant, and heat-resistant fabric of the present invention is formed by weaving warp yarns made of composite yarns and weft yarns made of combined yarns. The above-mentioned warp consists of a core made of steel wire, a first covering yarn made of PET yarn that covers the core, and a second covering yarn made of P-ARAMID braided yarn that covers the core covered by the first covering yarn in the opposite direction. The above examination is performed using steel wire to improve cut resistance. It is preferable that the steel wire has a diameter of 0.01 to 0.03 mm. If the diameter of the steel wire is less than 0.01 mm, the weaving performance is excellent but the improvement in cut resistance is low, and if it exceeds 0.03 mm, the steel wire layers collapse during the twisting of the composite yarn, causing frequent defects in the composite yarn and a problem with the fabric's appearance being poor. The first covering yarn above consists of a PET yarn that is covered in the above examination to improve the overall mechanical strength of the composite yarn and fabric. In particular, it is preferable that the first covering yarn be made of PET yarn with a fineness of 50 to 100D. If the fineness of the PET yarn is less than 50D, it is difficult to effectively cover the core yarn, resulting in poor fabric texture, and if the fineness exceeds 100D, the PET yarn is too thick, causing defects during the covering process. And the second covering yarn is made of a P-ARAMID braided yarn that covers the core covered by the first covering yarn in the opposite direction to the first covering yarn in order to improve cut resistance and heat resistance. In particular, it is preferable that the second covering yarn be composed of 15 to 30's P-ARAMID braided yarn. If the fineness of the P-ARAMID braided yarn is less than 15's, there is a problem that defects occur during the covering process because the P-ARAMID braided yarn is too thick, and if it exceeds 30's, there is a problem that the cut resistance and heat resistance are poor. In addition, the above weft yarn is made of P-ARAMID plied yarn to improve cut resistance and heat resistance. In particular, it is preferable that the above weft yarn be made of 15 to 30's P-ARAMID plied yarn. If the fineness of the P-ARAMID plied yarn is less than 15's, the P-ARAMID plied yarn is too thick and the weaving performance is poor, and if it exceeds 30's, there is a problem with poor cut resistance and heat resistance. It is preferable that the above warp and the above weft are woven in a modified twill structure. As the fabric is formed in a modified twill structure, the above weft is exposed more on the surface and the above warp is positioned on the inside, which has the advantage of further improving heat resistance and cut resistance. As such, the fabric of the present inv
