Abstract:
Reactive geocomposite mats, and their method of manufacture, for treating contaminants in soil or water that allow the passage of essentially non-contaminated water therethrough. The geocomposite mat includes a pre-formed woven or non-woven geotextile, having a thickness of about 6 mm to about 200 mm, and having, a porosity sufficient to receive a powdered or granular contaminant-reactive material, contaminant- sorptive material, or a contaminant-neutralizing material (hereinafter collectively referred to as "contaminant-reactant material" or "contaminant-reactive material") throughout its thickness, or in any portion of the thickness across its entire major surface(s). The powdered or granular contaminant-reactive material is disposed within the pores of the previously formed, high loft geotextile mat to surround the fibers, e.g., by vacuum or vibrating the high loft mat while in contact with the contaminant-reactive material to allow the powdered or granular contaminant-reactive material to flow by gravity into the pores of the previously formed geotextile and vibrational forces. Liquid-permeable cover sheets are adhered to the upper and lower major surfaces of the filled geotextile to prevent the powdered or granular material from escaping from the geotextile during transportation and installation. ® KIPO & WIPO 2007
Abstract:
A waterproof, breathable, recyclable, layered composite fabric with stretch that is especially well-suited for weather protection garments and the like, has at least one layer of a woven, knitted, or non-woven face fabric of stretch-recovery bicomponent fibers, and an elastomeric waterproof film or coating of the same polymer, and optionally a liner fabric of knitted construction. The composite fabric is recyclable using traditional techniques to recycle polyester or polyamide. Garments made from this fabric are also disclosed.
Abstract:
부직 폴리올레핀 시이트는 성형가능한 터프트된 자동차용 카페트를 제조하는데 사용되는 카페트 1차 배면제로서 유용하다. 폴리올레핀 특히 폴리프로필렌 시이트가 다수의 방사공으로부터 용융 방사된 후 방사된 필라멘트는 연신이 증대됨에 따라 필라멘트가 높은 신장율에서 낮은 신장율로 변함에 있어서, 높은 필라멘트 신장율을 유지하기 위해 2.0 미만의 연신율로 연신되는 것에 의해 제조된다. 연신된 필라멘트는 기계 방향 및 기계 교차 방향의 양방향 모두로 움직이는 집속 벨트위에 부착되므로써 100 내지 150 g/㎡의 단위 중량을 갖는 부직 시이트를 형성하게 된다. 생성된 시이트는 증기 접착기에서 가볍게 접착된 후, 탈착되어 시이트의 두께가 2.5 내지 3.5배 내의 범위로 증가된다. 터프트된 시이트는 최소 40%의 신장율을 갖는다. 본 발명은 터프트된 성형가능한 카페트로서 탈주형 이후에 그 형상을 유지하는 반면에 찢어지거나 주름 잡히거나 그라이닝(grining)되는 것에 견딜 수 있는 것을 만들기 위하여 기계 방향 및 기계 교차 방향의 양방향에서의 터프트된 시이트의 신장을 위한 시이트의 높은 강도를 희생시키는 것이다.
Abstract:
The penetration of an adhesive into yarn on the underside of a prim. backing of a textile covering is improved by applying to the yarn prior to applying the adhesive an aq. dispersion comprising a surfactant and/or a polymeric component, the surface tension of the aq. dispersion being equal to or less than that of the yarn. The method is useful on nylon, polypropylene, acrylic, polyester, cotton or woollen yarns which may have been pretreated to be resistant to foreign materials.
Abstract in simplified Chinese:本发明提供一种使用于形成簇绒地毯之基底地毯衬垫,,其消除或减少对于一乳胶黏接层或使用一第二衬垫之需要。将一编织或非编织纤维底板之外表面用具有比该底板之纤维低之熔化温度的热塑性聚合物粒子涂覆。该底板在纤维之间拥有足够的开口以能够经受簇绒。在簇绒之后,将该簇绒底板热处理,以熔化该等热塑性聚合物粒子且在该簇绒地毯纱线纤维与该基底衬垫底板之间形成一黏结。
