摘要： A web-type composite intermediate is formed from fibers and plastic. The composite intermediate is formed by wet web formation from a substantially homogeneous liquid mixture which contains natural fibers, plastic particles having a diameter of less than approximately 1000 μm, and an agent that improves compatibility between natural fibers and plastic particles. In addition, a method for forming a composite intermediate and the use of the composite intermediate are also described.

摘要： A method of making a fabric-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a nascent web. The nascent web is applied to a translating transfer surface and is fabric-creped from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric. The creping fabric travels at a fabric speed that is slower than the speed of the transfer surface. The nascent web is creped from the transfer surface and redistributed on the creping fabric to form a creped web with a drawable reticulum having a plurality of interconnected regions of different local basis weights. The creped web is dried to form a dried web, and the dried web is drawn. The drawing step includes drawing the dried web between a first draw roll and a second draw roll.

摘要： A method for treating a paper to provide at least a part of it with anisotropic electric conductivity, by i) applying to the paper a dispersion comprising a non-aqueous, liquid dispersing agent and conductive particles, ii) applying an electric field over at least part of the paper, so that a number of the conductive particles are aligned with the field, thus creating conductive pathways, and wholly or partially eliminating the dispersing agent and allowing the paper to dry thereby stabilizing and preserving the conductive pathways in the paper as well as paper so produced. The paper may alternatively be prepared from a cellulose dispersion comprising conductive particles and subjecting the dispersion for similar aligning of the conductive particles.

摘要： An absorbent cellulosic sheet having variable local basis weight includes a papermaking-fiber reticulum provided with (i) a plurality of cross-machine direction (CD) extending, fiber-enriched pileated regions of relatively high local basis weight interconnected by (ii) a plurality of elongated densified regions of compressed papermaking fibers. The elongated densified regions have relatively low local basis weight and are generally oriented along the machine direction (MD) of the sheet and have an MD/CD aspect ratio of at least 1.5. The products are most preferably prepared by way of a compactive dewatering/wet crepe process.

摘要： Provided is a process for preparing a smooth and glossy surfaced paper web. The process comprises subjecting the paper web to shear by using calender rolls driven at different speeds or calender rolls with different diameters. The resulting paper has a totally different structure than the original paper, as it has a much smaller void structure and a much higher degree of bonding between the elements of the sheet. The process is particularly applicable to improving the electrical insulation properties of an aramid paper web.

摘要： A fibrous, flat and ion-permeable material made of synthetic fibers, in particular of synthetically spun fibers such as acrylic fibers or aramid fibers, is processed into staple fibers of a specific length and then fibrillated. In a wet-laid inclined machine (paper machine), the fibrillated fibers are formed into a continuous web and then the web or portions of it are subjected to a temperature treatment to make the web electrically conducting by carbonizing/graphitizing the web through heating.
