摘要： A process for drying/heat-treating nonwoven webs in which the web (1) is partially dried under tension in a first drying zone (2) and further heat treated under low tension or in a substantially tensionless state a second drying zone (6, 7). The process significantly reduces the occurrence of stretch-type defects in the nonwoven webs.

摘要： A spunbond nonwoven fabric is provided which is formed from continuous multiple component filaments which include a polyester component and a polyethylene component. The polyethylene component is a blend of high density polyethylene and a first linear low density polyethylene. The spunbond filaments are preferably formed in a sheath-core configuration with the polyester component in the core and the polyethylene component in the sheath. Composite sheets are provided which include the multiple component spunbond layer and a meltblown layer, wherein the meltblown fibers include a second linear low density polyethylene. The linear low density polyethylenes are preferably formed by polymerization of ethylene with an alpha-olefin co-monomer, where the same co-monomer is used in each of the first and second linear low density polyethylenes.

摘要： This invention provides a process for making a nonwoven sheet of substantially continuous melt spun fibers by extruding melt spinnable polymer containing at least 30 % by weight low IV poly(ethylene terephthalate), drawing the extruded fiber filaments at a rate of at least 6000 m/min, laying the fiber filaments down on a collection surface, and bonding the fiber filaments together to form a nonwoven sheet. The invention further provides a nonwoven sheet comprised of at least 30 % by weight poly(ethylene terephthalate) having an intrinsic viscosity of less than 0.62 dl/g, where the sheet has a basis weight of less than 125 g/m2, and a grab tensile strength of at least 0.7 N/(g/m2).

摘要： A meltblown fiber comprising at least 20% by weight polyester selected from the group consisting of poly(ethylene terephthalate) having an intrinsic viscosity of less than 0.55 dl/g and poly(trimethylene terephthalate) having an intrinsic viscosity of less than 0.80 dl/g is provided. The meltblown fibers are collected as a web that can be incorporated into composite sheet structures.

摘要： A composite sheet is provided that includes a first fibrous layer having a first side and an opposite second side, and a second fibrous layer bonded to the first side of the first fibrous layer. The first fibrous layer is a multiple component meltblown web comprised of at least 95 % by weight of meltblown fibers having an average effective diameter of less than 10 microns. The meltblown web is comprised of 10 % to 98 % by weight polyethylene and 90 % to 2 % by weight of a synthetic fiber forming polymer having a melt temperature greater than 140 °C or a glass transition temperature of at least 40 °C. The second fibrous layer is comprised of at least 95 % by weight of second layer fibers having an average effective diameter that is greater than the average effective diameter of the meltblown fibers of the first fibrous layer. The composite sheet has a basis weight of less than 120g/m2, a grab tensile strength of at least 35 N, and a hydrostatic head of at least 10 cm.

摘要： This invention relates to a new nonwoven material which has very high Frazier permeability while having substantial hydrostatic head liquid barrier properties. The material is comprised of fibers which are approximately one denier and finer fibers which have sufficient strength properties so as not to need a support scrim. The fabric is quite comfortable because of its breathability, quite soft because of its construction, and protective from liquids from rain to hazardous chemicals.
