    摘要: A nonwoven composite web consists of 15 to 50 wt. % of first polyester fibers having a first length, a first denier and a first melting temperature; 15 to 50 wt. % of second polyester fibers having a second length, a second denier and a second melting temperature; 15 to 50 wt. % of third polyester fibers having a third length, a third denier and a third melting temperature; 10 to 35 wt. % of polypropylene fibers; and 1 to 25 wt. % of cellulose fibers. The first, second and third lengths are no less than 1/2 inch, the first, second and third denier are no less than 1.5, and the third melting temperature is less than the first and second melting temperatures respectively. The first and second polyester fibers, the polypropylene fibers and the cellulose fibers are bonded to each other at least in part by solidification of the third polyester fibers after subjecting the web to temperatures in excess of the third melting temperature but not in excess of the first and second melting temperatures. In particular, the web is thermally bonded by calendaring at a temperature of approximately 385.degree. F. The web can be manufactured to have high opacity by adding titanium dioxide and silicone-acrylic latex to the composition. The titanium dioxide and latex are agglomerated and the resulting agglomerates are thermally bonded to the fiber matrix.

    摘要: A nonwoven composite web is formed by a wet process on a papermaking machine. The web coming off the papermaking machine is dried and thermally bonded using heated calendar rolls. The nonwoven composite material is made from a furnish of polymeric staple fibers, a first binder fiber consisting, at least in part, of a first thermoplastic binder material which melts at a first melting temperature less than and a second binder fiber consisting, at least in part, of a second polymeric material which has second melting temperature which is higher than the first melting temperature. The first polymeric material is selected to have a first melting temperature less than the temperature to which the first material will be subjected in the papermaking machine. The melted first polymeric material gives the web strength on the papermaking machine. The second polymeric material is selected to have a second melting temperature less than the temperature to which the second material will be subjected in the calendar rolls. Thus, the second polymeric material is melted as the web passes through the calendar rolls and thermally bonds the other fibers of the web when the melted second polymeric material fuses upon cooling. The staple fibers are made of polyester and the bicomponent binder fibers are of the co-polyester/polyester sheath/core variety. The support substrate has a sheet porosity in the range of 5-10 cfm.

    摘要: An in-mold label material is a nonwoven mat of fibers having one side fused with the outer surface of a polymeric container and the other side coated with a pigment-containing latex suitable for printing thereon. The label paper is manufactured from commercially available fibers combined in water into a homogeneous mixture and then formed into a mat employing a wet-lay process. For use with polyethylene containers, the label may be a web consisting of 88-100% polyethylene fibers and 0-15% polyvinyl alcohol fibers or 70-100% polyethylene fibers, 0-15% polyvinyl alcohol fibers and 0-30% polypropylene fibers. For use with polyester containers, the label may be a web consisting of 50-90% polyester staple fibers, 10-40% bicomponent polyester/co-polyester, core/sheath binder fibers and 0-10% polyvinyl alcohol binder fibers thermally bonded together. The nonwoven web of fibers has a pigmented coating. After the material has been cut into labels, the labels may be applied to the blow-molded containers in-mold without the use of an adhesive material using a conventional in-mold labeling technique or post-mold using adhesive.

    摘要: A nonwoven composite web suitable for use, after post-treatment with a wetting agent, as a battery separator is formed by a wet process on a papermaking machine. One nonwoven composite material is made from a furnish of polyolefin binder fibers and polyolefin staple fibers. The web coming off the papermaking machine is dried using infra-red dryers followed by heated dryer cans. After drying, the web is thermally bonded using heated calendar rolls. The polyolefin binder fibers melt as the web passes through the calendar rolls and thermally bond the polyolefin staple fibers of the web when the melted binder fiber material fuses upon cooling.
