Description
본 발명은 산업현장에서 작업자가 착용하는 산업안전작업복의 원단으로 사용할 수 있는 산업안전작업복용 복합시트에 관한 것이다. The present invention relates to a composite sheet for industrial safety work clothes that can be used as a fabric of industrial safety work clothes worn by workers in the industrial field.
산업현장에서 작업자가 착용하는 안전작업복은 고강도, 내열성 및 내화학성을 필요로 한다. 예를 들면 위험한 용도에 사용되는 방탄복, 공업용 작업복, 소방복 및 군인의 보호복은 면이나 모와 같은 비합성 섬유로 된 실로 짠 직물로 만든 후 이들 직물을 통상적인 할로겐과 인 또는 이들 중 하나에 기초한 내화제로 처리하여 사용하였는데, 이러한 작업복은 활동에 제한을 받고 일반적인 비내열성 직물보다 더 무거운 문제가 있었다. Safety work clothes worn by workers in industrial sites require high strength, heat resistance and chemical resistance. For example, body armor, industrial workwear, fire fighting clothing, and military protective clothing for hazardous use are made of woven fabrics of non-synthetic fibers such as cotton or wool, and these fabrics are fire-resistant based on conventional halogen and phosphorus or one of them. Used in zero treatment, these workwear is limited in activity and has a heavier problem than normal non-heat resistant fabrics.
상기 산업안전작업복 중에서도 특히 용접 작업시 착용하는 용접복은 내열성 및 난연성이 더욱 필요로 하는 작업복에 속한다. 특히 아크 용접 작업시에는 용접작업 과정에서 많은 불꽃이 튀며, 전기에 의한 감전, 용접시 발생되는 고온의 열기 및 작업장에서 예상치 못한 외부 충격 등의 위험요소가 상존하고 있다.Among the industrial safety work clothes, in particular, the welding clothes worn during welding work belong to the work clothes that need more heat resistance and flame retardancy. In particular, during arc welding, many sparks are splashed during the welding process, and there are risk factors such as electric shock due to electricity, high temperature heat generated during welding, and unexpected external shock in the workplace.
이러한 위험요소로부터 작업자를 보호하기 위해 용접복, 용접 마스크 및 용접 장갑 등의 용접용 보호장구(Welding Gear)를 착용하게 되며, 이 중 용접복은 특히 자신의 신체의 대부분을 보호하기 때문에 다른 보호장구에 비해 더 중요하다. 종래의 용접복은 동물의 가죽으로 제작되었는데, 이와 같이 가죽으로 제작된 용접복은 용접 작업시 불꽃이 튀어 닿게 되면 고온의 열에 의해 쉽게 오그라들거나 소실되며, 무겁고 불편할 뿐 아니라 통풍이 되지 않는 문제점이 있었다.To protect workers from these hazards, welding gear such as welding suits, welding masks and welding gloves are worn. Among them, other welding suits protect the majority of the body. More important than that. Conventional welding suits are made of animal leather, but the welding suit made of leather is easily deformed or lost due to high temperature heat when sparks come into contact during welding, and is not only heavy and uncomfortable, but also does not have ventilation. .
최근에는 비연소성 및 내열성이 우수한 파라-아라미드, 메타-아라미드, 탄화섬유, PBO, 방염성 레이온등의 고강도ㆍ고내열성 섬유를 이용한 용접복을 개발하기에 이르렀으나 이러한 직물은 우수한 열적안정성은 보였지만 단섬유 형태여서 방적사로 제조하여 사용하는 경우가 많았으며, 이러한 고강도ㆍ고내열성 섬유의 방적사의 경우에 필링성이 좋지 못한 문제점을 가지고 있었으며, 이러한 필링성을 개선하기 위해서는 수지가공을 하여야 하였으나 내열성이 저하되는 문제점을 가지고 있었다.Recently, we have developed welding suits using high-strength and high heat-resistant fibers such as para-aramid, meta-aramid, carbonized fiber, PBO, flame retardant rayon, etc., which have excellent non-combustibility and heat resistance. Due to its shape, it was often manufactured and used as a spun yarn, and in the case of the spun yarn of such high strength and high heat resistant fibers, the peeling property had a poor problem. To improve the peeling property, resin processing had to be performed, but the heat resistance was degraded. Had a problem.
이에 대한민국특허공고번호특1992-0001037호에서는 천연섬유 또는 합성섬유인 중합성 재료와 비가역적으로 열 고정된 난연성 탄소질 섬유와의 블랜드를 포함하는 방화 및 방염성을 향상시킨 섬유구조체를 제공하고 있으나, 상기 선행기술은 섬유구조체의 구성섬유로서 신율(%)이 낮은 탄소질 섬유를 사용하고 있어 의복제조시 형태안정성이 현저히 저하되는 문제점이 있었다. Accordingly, Korean Patent Publication No. 1992-0001037 provides a fiber structure having improved fire resistance and flame retardancy, including a blend of a polymerizable material which is a natural fiber or a synthetic fiber and an irreversibly heat-fixed flame retardant carbonaceous fiber. The prior art uses a carbonaceous fiber having a low elongation (%) as a constituent fiber of the fibrous structure, which has a problem in that morphological stability is significantly lowered during garment manufacturing.
따라서 본 발명에서는 종래기술의 문제점인 형태안정성의 저하문제를 극복하면서도 방염성 및 방화성이 우수하고 제조가 간편한 산업안전작업복용 복합시트를 제공하는 것을 기술적과제로 한다.Therefore, in the present invention, it is a technical problem to provide a composite sheet for industrial safety work clothes which is excellent in flame retardancy and fire resistance and is easy to manufacture while overcoming the problem of deterioration in shape stability, which is a problem of the prior art.
그러므로 본 발명에 의하면 산화폴리아크릴로니트릴섬유와 인계난연제 함유 폴리에스테르섬유로 이루어진 니들펀칭부직포층; 및 상기 니들펀칭부직포층의 이면에 형성된 폴리에스테르 트리코트편물층으로 이루어지는 것을 특징으로 하는 산업안전작업복용 복합시트가 제공된다.Therefore, according to the present invention, a needle punched nonwoven layer made of polyacrylonitrile oxide fiber and polyester fiber containing phosphorus flame retardant; And a polyester tricoat knitted layer formed on the back surface of the needle punched nonwoven fabric layer.
또한, 본 발명에 의하면 산화폴리아크릴로니트릴섬유 60~90 중량%, 및 인계난연제 함유 폴리에스테르섬유 10~40 중량%의 단섬유를 혼합하여 일정하게 개면하는 개면공정;In addition, according to the present invention, the opening step of constantly opening the mixture of 60 to 90% by weight of polyacrylonitrile oxide fiber, and 10 to 40% by weight of the phosphorus flame retardant-containing polyester fiber;

이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명의 산업안전작업복용 복합시트는 도 1에 도시된 바와 같이 고강도, 고내열성의 물성을 가지는 산화폴리아크릴로니트릴섬유와 난연성 및 기계적 물성이 우수한 인계난연제 함유 폴리에스테르섬유를 혼합하여 니들펀칭한 니들펀칭부직포층(1)과 폴리에스테르 트리코트편물층(2)이 결합하여 이루어진다.The composite sheet for industrial safety work clothes of the present invention is needle punched by mixing a polyacrylonitrile oxide fiber having a high strength and high heat resistance and a phosphorus flame retardant-containing polyester fiber excellent in flame retardancy and mechanical properties as shown in FIG. The needle punched
상기 니들펀칭부직포층의 구성섬유 중 하나인 상기 산화폴리아크릴로니트릴섬유는 폴리아크릴로니트릴전구체를 200~300℃의 온도범위에서 서서히 공기중에서 산화처리한 것으로서, 폴리아크릴로니트릴전구체로부터 PAN계 탄소섬유를 만드는 공정중에서 산화공정만을 거친 탄화온도가 높은 산화폴리아크릴로니트릴섬유를 사용하여 부직포층에 고내열 물성을 부여하게 되는 것이다. PAN계 전구체의 지방족 탄소의 산화에 의해 가교반응이 일어나고 나프티리딘이나 피리돈, 피리미딘등의 가교구조가 생기고 다시 축합이 진행되면 축합벤젠고리를 거쳐서 환상직선의 고분자물로 되는데, 필요에 따라서는 섬유축방향으로 연신을 하거나 황화처리를 한 것을 사용할 수도 있다. The polyacrylonitrile oxide fiber, which is one of the constituent fibers of the needle punched nonwoven fabric layer, is a polyacrylonitrile precursor which is gradually oxidized in air at a temperature range of 200 to 300 ° C., and is a PAN-based carbon from a polyacrylonitrile precursor. In the process of making fibers, polyacrylonitrile oxide having high carbonization temperature, which has undergone only an oxidation process, is used to impart high heat resistance properties to the nonwoven fabric layer. When crosslinking reaction occurs by oxidation of aliphatic carbon of PAN precursor, and crosslinking structure such as naphthyridine, pyridone, pyrimidine is formed, and condensation progresses again, it becomes cyclic linear polymer through condensation benzene ring. Stretching or sulfiding in the fiber axis direction can also be used.
상기 산화폴리아크릴로니트릴섬유는 섬도 0.5~5dpf, 섬유장 38~100㎜인 것을 사용하는 것이 균일한 구성섬유의 분포를 가지는 부직포 형성에 바람직하다. 또한, 상기 니들펀칭부직포층의 구성섬유 중 다른 하나인 인계난연제 함유 폴리에스테르섬유는 난연성을 보충함과 동시에 집속성을 보충하여 부직포층에 우수한 기계적인 물성을 부여하게 되는 것이다.
It is preferable that the polyacrylonitrile oxide fibers have a fineness of 0.5 to 5 dpf and a fiber length of 38 to 100 mm to form a nonwoven fabric having a uniform distribution of constituent fibers. In addition, the phosphorus-based flame retardant-containing polyester fiber, which is one of the constituent fibers of the needle punched nonwoven fabric layer, supplements flame retardancy and at the same time, imparts excellent mechanical properties to the nonwoven fabric layer.
상기 니들펀칭부직포층은 산화폴리아크릴로니트릴섬유와 인계난연제 함유 폴리에스테르섬유가 6:4~9:1로 혼합되는 것이 형태안정성이 우수한 부직포층 형성에 바람직하며, 상기 니들펀칭부직포층의 무게가 170~270g/㎡ 인 것이 산업안전작업복으로 제작시 증량감을 줄여 의복에 의한 피로도를 줄여 줄 수 있다.The needle punched nonwoven fabric layer is preferably a mixture of polyacrylonitrile oxide fibers and a phosphorus flame retardant-containing polyester fiber in a range of 6: 4 to 9: 1 to form a nonwoven fabric having excellent shape stability, and the weight of the needle punched nonwoven fabric layer is 170 ~ 270g / ㎡ can reduce the fatigue caused by clothing by reducing the increase in the production of industrial safety work clothes.
본 발명의 산업안전작업복용 복합시트에서는 상기 니들펀칭부직포층의 이면에 폴리에스테르 트리코트편물층이 형성되는데, 폴리에스테르 트리코트편물층은 우수한 신축성과 형태안정성을 가져 상기 니들펀칭부직포층이 쉽게 형태가 늘어나서 돌아오지 않는 문제점을 보완하여 전체적인 산업안전작업복용 복합시트의 형태안정성을 향상시킬 수 있게 되는 것이다. 만일 폴리에스테르 트리코트편물층이 형성되지 않는 경우에는 신축성에 대한 문제점이 발생되며, 트리코트편물층이 아닌 평직, 능직등의 직물이 형성되는 경우에는 산업안전복의 활동성 저하의 문제점이 발생할 수 있게 된다.In the composite sheet for occupational safety work clothes of the present invention, a polyester tricoat knitted layer is formed on the back side of the needle punched nonwoven fabric layer, and the polyester tricoat knitted layer has excellent elasticity and shape stability so that the needle punched nonwoven fabric layer is easily formed. This will improve the shape stability of the composite sheet for occupational safety work by supplementing the problems that do not come back. If the polyester tricot knit layer is not formed, there is a problem about elasticity, and when a fabric such as plain weave or twill weave is formed instead of the tricot knit layer, a problem of deterioration of activity of the industrial safety suit may occur. do.
본 발명의 산업안전작업복용 복합시트를 이용하여 산업안전복을 제조하기 위해서는 산업안전작업복용 복합시트를 그대로 사용할 수도 있으며, 상기 폴리에스테르 트리코트편물층의 이면에 면직물이나 합성섬유직물을 핫멜트로 부착하여 사용하여 착용자의 피부트러블을 방지할 수 있다. In order to manufacture industrial safety clothing using the industrial safety workwear composite sheet of the present invention, the industrial safety workwear composite sheet may be used as it is, and a cotton fabric or a synthetic fiber fabric is attached to the back side of the polyester tricoat knitted fabric layer with a hot melt.
