Abstract

An objective of the present invention is to manufacture an aramid-covered yarn having tensile strength, toughness, heat resistance, elasticity, high strength, and high elasticity so as to provide fabrics which can be used as a core material of a diaphragm. To this end, according to the present invention, an aramid w-covered yarn for weaving a core material of a diaphragm is configured such that polyurethane fibers having 420-1000 denier are prepared as a core yarn, and aramid fibers having 200-1500 denier are twisted to the polyurethane fibers in a covering machine at 500 TPM (twist per meter) so as to provide an aramid-covered yarn for a core material of a diaphragm, wherein the core yarn made with the polyurethane fibers has a span function, and the aramid fibers configuring the aramid w-covered yarn have tensile strength, toughness, heat resistance, high strength, and high elasticity. The fabrics for a core material of a diaphragm woven with the aramid w-covered yarn configured as described above can be woven into a plain weave when the fabrics are required to be thin or into a double-layered weave when the fabrics are required to be thick, according to a desired use. Thus, regular concave-convex portions can be applied to a surface of the fabrics, thereby greatly increasing bonding properties with a diaphragm body when used as a core material of a diaphragm, and therefore, durability of the diaphragm can be significantly improved.

다이어프램의 심재 직조용 아라미드 w커버링사 및 아라미드 w커버링사로 직조된 다이어프램 심재용 직물{Diaphragm-based fabrics woven into aramid w cover rings and aramid w cover rings for the slag weaving of the diaphragm}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diaphragm-woven fabric woven into an aramid w covering ring and an aramid w covering yarn,

본 발명은 산업용 각종 기기에 사용되고 있는 다이어프램을 제조시 심재용 직물로 사용하기 위한 다이어프램의 심재용 직물을 직조하기 위한 다이어프램의 심재 직조용 아라미드 w커버링사와, 상기 아라미드 w커버링사로 직조된 다이아프램 심재용 직물에 관한 것이다.The present invention relates to an aramid w covering yarn for core material of a diaphragm for woven fabric for a core material of a diaphragm for use as a core material fabric in a diaphragm used in various industrial devices, and a fabric for diaphragm core material woven with the aramid w covering yarn will be.

주지하는 바와 같이 다이아프램은, 금속 다이어프램과 비금속 다이어프램이 있으며, 탄성이 있는 얇은 막의 간막이 판의 형상으로, 재질은 천연 고무, 합성 고무, 금속판 등으로 형성되어 휨과 흡수하는 특성을 사용해서 산업용 각종 기기 부품에 사용되고 있다.As is known, the diaphragm has a metal diaphragm and a non-metal diaphragm. The diaphragm is formed as a partition plate of an elastic thin film. The material is formed of natural rubber, synthetic rubber, metal plate, etc., It is used for the parts of the device.

산업용 각종 기기들 중에 다이어프램 펌프의 경우에 다이어프램을 반복적으로 만곡시켜서 유체에 압력을 가하거나 만곡의 변위를 사용해서 압력의 측정과 유체의 개폐를 실행하거나, 격리용 막판(膜板), 밸브 또는 연료 펌프, 가스 압력 조정기, 제어 기계 등에서 직접 내용물인 기체, 액체에 작동 유체를 접촉시키지 않고 가동시키고자 할 때 사용된다.Among diverse industrial devices, diaphragm pumps are repeatedly bent to apply pressure to the fluid, or to measure the pressure and to open and close the fluid by using the displacement of the curvature, or to separate the diaphragm from the membrane plate, It is used to operate without contacting the working fluid to the gas or liquid which is the contents directly in the pump, the gas pressure regulator, and the control machine.

그리고, 차량의 차단 연결부에 취부되는 유연하고 변형 가능한 덮개, 차량의 연결부의 관통로를 형성하는 안 다이어프램, 차단연결부를 외부에서 차단하는 외 다이어프램, 방설 다이어프램 등이 있다.Further, there are a flexible and deformable lid that is attached to the interrupting connection portion of the vehicle, an inner diaphragm that forms a through passage of the connecting portion of the vehicle, an outer diaphragm which shields the interrupting connection portion from the outside, and a diaphragm diaphragm.

상기와 같이 산업분야에 다양하게 사용되는 다이어프램을 제조시 다이어프램의 내구성을 향상시키기 위하여 다이어프램의 내부에 심재를 넣어서 제조하고 있는데, 상기와 같이 심재로 사용되는 직물이 대부분 폴리에스테르와 같은 합성섬유로 직조된 직물을 사용하고 있다.In order to improve the durability of the diaphragm, diaphragms are manufactured by putting a core material inside the diaphragm. However, as described above, most of the fabrics used as core materials are made of synthetic fibers such as polyester, Is used.

상기와 같은 폴리에스테르로 직조된 직물은 내구성과 내열성이 약하기 때문에 다이어프램의 기능상 만곡의 변위를 반복하는 작용으로 인하여 균열과 마모 및 내열성이 크게 떨어지는 결과로 수명을 단축시키게 된다.Such a fabric woven with polyester has poor durability and heat resistance, and therefore functions as a diaphragm to repeatedly perform a displacement of its curvature, resulting in a significant reduction in cracks, abrasion, and heat resistance, thereby shortening the service life.

따라서, 다이어프램이 적용되는 산업용 각종 기기의 수명을 단축시켜 교체 및 보수에 따른 경제적인 손실이 발생할 뿐만 아니라, 다이어프램이 적용되는 산업용 각종 기기의 전체에 품질을 저하시키는 원인이 되는 등 다이어프램 심재용 직물에 많은 문제가 있다.Accordingly, the life of various industrial devices to which the diaphragm is applied is shortened, resulting in an economical loss due to replacement and repair. In addition, the diaphragm is used for many diaphragm fabrics there is a problem.
