    摘要： A process is disclosed for the preparation of highly pigmented fibrets, the product produced thereby and paper products containing the highly pigmented fibret. The fibret has a surface area of from 15 to 30 square meters per gram and comprises a polymeric host having an index of refraction of not more than 1.5 containing from 40 to 75 percent by weight of an inorganic light scattering pigment having an index of refraction of from 1.5 to 3.0. The fibrets are found to impart paper opacification to the same degree as wholly inorganic opacified paper products without many of the problems commonly associated with such prior art products.

    摘要： A battery separator is provided that has 30-70% polyolefin synthetic pulp, 15-65% siliceous filler and 1-35% by weight of long fibers having lengths of between 1/4 and 1 inch. The long fibers may be polyester fibers or glass fibers or a mixture. Cellulose may be included in an amount up to about 10%.A process for forming the battery separator is also revealed using standard paper making equipment but employing ionic copolymers containing acrylamide in cationic and anionic combination to give good affinity of the siliceous material and polyolefin. Alum and other processing aids are also included as are other procedural steps such as pressing the web.

    摘要： The invention is directed to cross-linked cellulose fibers wherein cellulose pulp is fluffed, aerated, and exposed to a reaction mixture comprising formaldehyde, hydrochloric acid and formic acid as finely divided droplets or vapors. The thus treated fibers are cured by subjecting the fibers to a hot air stream at a temperature of from about 180.degree.-200.degree. C. for a duration of a few seconds, followed by separation of the fibers from the gaseous effluents. The procedure which lasts less than about one minute provides cellulose fibers cross-linked with formaldehyde wherein the predominant amount of cross-linking occurs at the surface of the fibers rather than at the core of the fibers. The fibers have improved characteristics including flexibility, touch and feel, rendering the fibers highly useful in paper products.

    摘要： Fibrous structures in sheet form having from 10% to 90% by weight of pulp of cellulosic fibers cross-linked with formaldehyde, the predominant cross-linking being at the surface area of said fibers and in an amount sufficient to impart flexibility and softness to said fibers while retaining high water absorptivity, and 90% to 10% by weight of an additional binding product with the amount of the additional binding product being selected to ensure sufficient strength and cohesion to the structure of the sheet. The inclusion of the cellulosic fibers wherein the predominant amount of cross-linking is at the surface area of the fibers imparts excellent water absorptiveness to the fibrous structure and, in addition, provides good flexibility and touch and feel properties to the product.

    摘要： The invention relates to a supercalendered Kraft paper production for a release liner, which contains both non-recycled bleached chemical pulps and recycled pulp produced from release liner supercalendered Kraft paper. When highly specific raw material is used for recycling, the characteristics of the recycled pulp may be adjusted already upon recycling. The recycled pulp obtained from supercalendered Kraft paper that has been used as a substrate of a release liner may be used without further refining for manufacturing supercalendered Kraft paper. Excessive refining can thus be avoided and the compatibility of the recycled pulp may be optimized for supercalendered Kraft paper production. The non-recycled pulps may be refined less, as well. This leads to positive effects in supercalendered Kraft paper manufacturing process, such as improved dewatering and energy efficient drying. The produced paper demonstrates reduced shrinkage and improved dimensional stability, while maintaining sufficient quality for use as a substrate for a release liner. A supercalendered Kraft paper with improved sustainability is produced.
