내열성이 우수하고, 흡음성을 가지며, 제조 공정 중 발생되는 스크랩을 재활용할 수 있는 차량용 엔진룸의 제조방법이 개시된다. 상기 차량용 엔진룸 제조방법은 10 내지 150 mm의 길이를 가지는 탄소 섬유 및 열 가소성 섬유를 카딩하고, 니들펀칭하여 펠트층을 형성하는 단계; 상기 펠트층에 열 및 압력을 가하여 펠트 보드를 형성하는 단계; 및 상기 펠트 보드에 열을 가하고, 목적하는 형태로 형성되도록 성형하는 단계를 포함한다.
摘要:
This method is a production method which increases the abrasion resistance of nonwoven textiles used in the automotive sector, and it is characterized in that; it comprises the operation steps of mixing (A) of two or more fibers that have different melting points, application of opening, carding, and needle operations on said fiber on the texture production (B) line, and fiber root binding in a ram drying oven (C) without the need for using any chemical substance.
摘要:
Nonwoven web materials formed of a first outer accumulation, a second outer accumulation, and an inner accumulation of fibers are disclosed. The outer accumulations of fibers may form respective first and second macroscopic outer web surfaces. The webs may bear a pattern of thermal bonds impressed on either or both of the first and second macroscopic surfaces, at which the fibers of the first accumulation are thermally bonded to fibers of the second accumulation. Fibers of the inner accumulation may be interlaced among the fibers of the first and/or second accumulations and be present at the first and/or second macroscopic outer web surfaces. A related method for manufacturing nonwoven web materials is also disclosed.

본 발명은 폴리(1,4-사이클로헥산디메틸렌 테레프탈레이트) (Poly 1,4-cyclohexanedimethylene terephthalate, PCT) 중공사로 이루어진 쿠션재용 섬유기재에 관한 것이다. 본 발명의 PCT 소재로부터 내열성, 화학안정성, 탄력성 및 벌키성이 부여된 PCT 중공사로 이루어진 쿠션재용 섬유기재는 고유물성뿐 아니라, 중공섬유로 인한 경량성을 충족한다. 또한, 본 발명은 융점 280∼290℃을 가지는 PCT 중공사 80 내지 60중량%가 상기 PCT 중공사 대비 용융점이 낮은 바인더 섬유 40 내지 20중량%로 결속된 쿠션재용 섬유기재를 제공함으로써, PCT 소재의 고유물성뿐 아니라, 중공특성이 유지되어 경량성 및 쿠션기능이 최적화된다. 이에, 본 발명의 쿠션재용 섬유기재를 이용하여 경량성 및 우수한 쿠션기능을 갖춘 자동차 내장용 쿠션재를 제공함에 따라 종래 폴리우레탄 소재의 쿠션재를 대체할 수 있다.
摘要:
The invention relates to a needled web consisting of natural fibres and optionally modified viscose fibres, preferably acetate fibres. A self-supporting moulded part is produced from this nonwoven fabric by pressure and heat treatment.
摘要:
A reinforcing material suitable for use in footwear stiffeners, characterised in that the material comprises consolidated melt-spun fibres of hot-melt adhesive, e.g. polyester melting point about 60 DEG C, combined with bulk fibres, e.g. of 20 mm to 100 mm in length, in a ratio of adhesive fibres to bulk fibres between 20:80 and 80:20 by weight, said fibres having been entangled prior to consolidation under pressure and heat.
摘要:
The invention relates to nonwoven sheets that have an ability to elastically stretch in machine direction to a significant extent, while showing low elongation in cross machine direction. The invention also relates to a method for making such sheets.
