    • A flexible, adhesively attachable, thermal and acoustical insulating shield has a needled, flexible, fibrous batt (40) having an insulating layer (43) of insulating fibers (44) disposed between opposite binding layers (41, 42) of binding fibers (45). Binding fibers (45) of each binding layer (41, 42) are needledly disposed through the insulating layer (43) and opposite binding layer (41, 42) to provide tufts (46) of binding fibers (45) protruding from the opposite binding layer (41, 42) so as to form a tufted upper surface (47) and a tufted lower surface (48) of the batt (40). A flexible adhesive (50) is disposed and adhered substantially over the upper surface (47) and lower surface (48) of the batt (40) such that the tufts (46) on the upper and lower surfaces (47, 48) are secured to the surfaces by the adhesive. A flexible, protective foil (51) is permanently adhered by the adhesive (50) to the lower surface (48) of the batt. The shield may be flexed and pressed to configure and permanently attach the upper surface (47) to an object (1) to be shielded.
    • 挠性的,可粘附地连接在一起的隔热和隔音屏蔽具有针刺的柔性纤维絮垫(40),其具有设置在粘结纤维(45)的相对结合层(41,42)之间的绝缘纤维(44)的绝缘层 )。 通过绝缘层(43)和相对的结合层(41,42)针刺地布置每个结合层(41,42)的结合纤维(45)以提供从相对结合突出的结合纤维(45)的簇(46) (41,42),以形成棉胎(40)的簇绒上表面(47)和簇绒下表面(48)。 柔性粘合剂(50)基本布置并粘附在棉胎(40)的上表面(47)和下表面(48)上,使得上表面和下表面(47,48)上的簇(46)被固定 通过粘合剂到达表面。 柔性保护箔(51)通过粘合剂(50)永久地粘附到棉胎的下表面(48)。 屏蔽件可以被弯曲和按压以将上表面(47)构造并永久地附接到待屏蔽的物体(1)。
