  • Publication number: 20090260768
    Abstract: A paper containing citrus peel fiber contains 20 to 60 weight parts of citrus peel fiber with respect to 100 weight parts of paper mulberry fiber. The citrus peel fiber is a peel fiber of one selected from the group consisting of mandarin orange, lemon, orange, Kiyomi and Dekopon. The paper containing citrus peel fiber is excellent in tensile strength, tear strength, bursting strength and folding endurance, and has superior preservability with pH close to neutrality. The paper containing citrus peel fiber of the invention also has a yellowish and/or reddish aesthetic color, excellent tactile sensation and high vapor transmission, and thus is adequate to be used as high grade wall paper and window paper. Furthermore, since the paper containing citrus peel fiber of the invention is manufactured by using by-products created in the course of processing citruses, it is possible to reduce manufacturing costs as well as decrease waste, thereby preventing pollution.

  • Publication number: 20080302494
    Abstract: The present disclosure includes a regenerated cotton board material comprised of dry cut cotton lint fiber, and wood fiber. The regenerated cotton board material may further include non-cellulosic fibers such as synthetic fibers or other natural fibers. In an alternate embodiment, a cotton board material may be manufactured from a mixture of dry cut cotton lint fiber and a binder material. A method for forming a regenerated cotton board material according to the present disclosure includes forming an aqueous slurry fiber furnish from a combination of dry cut cotton lint fiber, and wood fiber. The fiber furnish is then wet processed, calendared to remove the bulk of the water, and dried.

  • Patent number: 7402225
    Abstract: The process according to the invention comprises: a step in which chopped filaments and discontinuous PVOH fibers are dispersed in a process water, followed by a step in which a bed is formed in a forming device by passing the dispersion over a forming cloth through which the process water is drained, the filaments and fibers being retained on said cloth, followed by a heat treatment step in a stoving device. The PVOH fibers impart rigidity to the bed of fibers being formed. This process provides a veil with a very high tensile strength for low proportions of binder.
