발수성 VS 내수성

Water repellency (발수성) is a step up from water resistance, which means water cannot easily penetrate the material. Instead, water beads on the outside. The technical term for this is “hydrophobic”.

1>발수도(Water Repellency)와 2>내수도(Water Resistance)의 차이점은 ?
1>발수성은 섬유,실,옷감의 습윤에대한 저항성이며,일명 통기성 방수성이라고도 하지요.

따라서 이 발수성 시험은 외부의 비나 눈 등의 내부 침투를 막고,투과가 가능한 공기로 쾌적한 의복의 기후를 유지하기 위해 필요한 특성으로 표면 습윤 저항을 측정하는 것이다.

2>내수도란 물의 누수 또는 침투에대한 직물의 저항성을 뜻하며,의류용이나 산업재료로 사용되는 섬유제품 중에서 방수성,투수성 등 용도에 따라 여러가지 형태의 물에 대한 저항성이 요구되며,시험방법도 각기 다르다.
