Preparation Method of Cotton Bast Fiber and Chitosan Composite Non-woven Fabric for Filtration
The present invention discloses a preparation method of a cotton bast fiber and chitosan composite non-woven fabric for filtration and belongs to the technical field of fiber materials. The preparation method adopts steam flash explosion for pretreatment to separate cotton bast first, then a papermaking method is used for forming, finally chitosan is added to enhance the mechanical performance and improve the filtration efficiency, and a technological process is simple, environmentally friendly and suitable for industrial production. The non-woven fabric adopts lignin-rich cotton bast fibers and chitosan as raw materials, so that the non-woven fabric has good antibacterial performance. The cotton bast and chitosan used in the preparation method are both bio-based materials which can be degraded in the natural environment after use, so that burdens caused to the environment are reduced. At the same time, the problem that electrospinning methods are difficult to use in industrialized and mass production is avoided.

MOLDED FIBER ARTICLES WITH RIBBING STRUCTURES
According to examples, instructions may cause a processor to determine an intended physical property level that an article is to have when the article is formed, in which the article is to be formed through a molded fiber formation process. The instructions may also cause the processor to determine a thickness and a ribbing structure that the article is to have when the article is formed for the article to have the intended physical property level while a volume of fibers used to form the article is optimized. The instructions may further cause the processor to generate a three-dimensional (3D) digital model of the article to have the determined thickness and ribbing structure.

METHOD FOR FABRICATING SHAPED PAPER PRODUCTS
A method for fabricating shaped-paper products is introduced herein, which comprises at least one dredging-pulp step for forming a wet pulp made of paper-slurry materials, at least one pre-compression step for lightly compressing the wet pulp to form a first semi-finished product, at least one thermo-compression forming step for deeply compressing the first semi-finished product to form a second semi-finished product, and a surface-coating step of employing a product surface coating apparatus to coat a liquid coating materials onto at least one outer surface of the second semi-finished product, and thereby forming each of the shaped-paper products having a binding layer. With utilization of the present invention, an automatic coating can be applied high efficiently in a series of continuous production machines. This could not only shorten processing time and benefit a mass production thereof but also ensure a higher production yield and quality.
