본 발명은 섬유들이 함께 결합하여 자가-유지 웹을 형성하기에 충분한 양으로 존재하는 중합체성 결합제에 의해 섬유들이 결합되어 있는, 화학적으로 결합된 섬유로부터 제조된 섬유질 기재에 관한 것으로, 당해 결합제는, 210 내지 215℉에서 90초 동안 드럼 건조시키고 300 내지 325℉에서 2분 동안 경화시킨 와트만 #4 CHR 크로마토그래피 페이퍼를 사용하여 20% 함침량에서 측정한 결합제의 기계 횡방향(CMD) 평균 습윤 인장 강도가 4500g/in 이상임을 특징으로 한다. 바람직하게는 섬유질 기재 중의 유리 포름알데히드의 양은 15ppm 미만이다. 본 발명의 유화중합체 결합제는 기재에서 섬유들을 함께 결합시키는 데 사용할 수 있으며, 염료, 안료 또는 다른 물질을 기재에 결합시키는 데 사용할 수 있고, 베이킹 재료로 사용할 수 있거나, 기재를 마감 또는 표면 처리하는 데 사용할 수 있다. 가교결합도가 높기 때문에, 결합되거나 유화중합체로 처리된 기재는 습윤 강도가 뛰어나고 내구성/내후성 및 물/용매에 대한 내성이 양호하다. The present invention relates to a fibrous substrate made from chemically bonded fibers, wherein the fibers are bonded by a polymeric binder present in an amount sufficient to bond the fibers together to form a self-retaining web, wherein the binder is Mechanical transverse (CMD) average wet tension of the binder measured at 20% impregnation using Whatman # 4 CHR chromatography paper, drum dried at 210 to 215 ° F. for 90 seconds and cured at 300 to 325 ° F. for 2 minutes. Its strength is 4500g / in or more. Preferably the amount of free formaldehyde in the fibrous substrate is less than 15 ppm. The emulsion binder of the present invention can be used to bond fibers together in a substrate, can be used to bond dyes, pigments or other materials to the substrate, can be used as a baking material, or to finish or surface treat the substrate. Can be used. Because of the high degree of crosslinking, the bonded or emulsified substrates have excellent wet strength and good durability / weather resistance and water / solvent resistance. 습윤 강도, 섬유, 결합제, 부직 제품, 제직 제품, 종이 제품, 유리섬유 Wet strength, fiber, binder, nonwoven products, woven products, paper products, fiberglass
