Abstract:
A non-woven fabric reinforced microporous polymer membrane for nonaqueous electrolyte batteries or capacitor and manufacturing method thereof. The polymer latex is prepared by copolymerizing water soluble polymer 100 parts, hydrophobic monomer 30-500 parts, hydrophilic monomer 0-200 parts and initiator 1-5 parts. According to 100% solids content of the polymer latex, adding 0-100% inorganic fillers and 20-100% plasticizers, and the paste is obtained. The two surface of the non-woven fabric are coated with the paste, drying, and the non-woven fabric reinforced microporous polymer membrane is obtained.

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:
표피재층(2)과, 부직포 흡음층(3)을 열가소성 수지 파우더를 가열 용융함으로써 형성된 통기성 접착 수지층(4)을 통하여 접착 일체화하고, 또한 카펫(1) 전체의 두께 방향의 통기도를 1∼50(㎤/㎠ ·초)으로 설정한다. 이것으로, 하측에서 침입하는 소음은 물론, 지붕, 도어, 창문 등을 통하여 상방측에서 차 실내 공간으로 침입하는 소음에 대하여도 뛰어난 흡음성을 발휘할 수 있다. 이러한 카펫은 표피재에 열가소성 수지 파우더를 산포한 후, 이 파우더를 가열 용융시키고, 이어서 그 위에 부직포를 적층한 상태로 가압함으로써 제조할 수 있고, 입자 직경 90∼10000㎛의 파우더를 산포량 5∼500g/㎡으로 산포하는 것이 바람직하다.

Abstract:
A composite roofing membrane containing a single ply roofing membrane containing a first membrane, a scrim, and a second membrane. The first side of the first membrane forms the upper surface of the composite roofing membrane and contains a thermoplastic polymer. The scrim has a machine and cross-machine direction and contains a yarn or fiber selected from the group consisting of polyester and glass, and a tensile strength in the machine direction is at least about 100 N/cm2. The second membrane contains a thermoplastic polymer. The composite roofing membrane also contains a fire resistant fleece containing a plurality of FR rayon staple fibers and a plurality of char scaffold fibers selected from the group consisting of partially oxidized acrylonitrile and silica staple fibers.
Abstract:
An upper surface layer 2 and a nonwoven fabric sound absorption layer 3 are integrally secured via an air permeable adhesive resin layer 4 formed by melting thermoplastic resin powder, and the air permeability of the thickness direction of the entire carpet 1 falls within the range of 1 to 50 cm3/cm2·second. This effectively absorbs noise from the upper side entering via a roof, doors and windows as well as noise from the lower side. The carpet can be manufactured by scattering thermoplastic resin powder on an upper surface member, heating the thermoplastic resin powder into melted thermoplastic resin, placing a nonwoven fabric on the upper surface member via the melted thermoplastic resin, and pressing the nonwoven fabric and the upper surface member in a laminated state. It is preferable that powder of particle size of 90 to 10,000 μm is scattered in the amount of 5 to 500 g/m2.
Abstract:
A floor covering made from a combination of solution dyed yarn and non-solution dyed yarn. The non-solution dyed yarn can first be combined with solution dyed yarn to form a pile fabric. Thereafter, the pile fabric can additionally be dyed or patterned in preparation for possible incorporation into a floor covering product.
Abstract:
An automotive tufted carpet with improved acoustic properties is formed with a two-part primary backing. The first backing layer is formed of a woven or non-woven material, and the second backing layer is formed of a microfilament spunlaced material possessing sound absorbing acoustic properties. The first backing layer and second backing layer are thermobonded together with an adhesive web positioned therebetween to form the two-part primary backing. Tufts of yarn are then sewn through the two-part primary backing. The resulting acoustically enhanced automotive tufted carpet may be backcoated or precoated, and may have a secondary backing adhered thereto as a matter of choice.
