摘要:
Cellulose materials and methods of making the cellulose materials are described herein. The method can include contacting a cotton fabric with an oxidizing system to obtain an oxidized cotton material and processing the oxidized cotton material to form the cellulose material. The oxidizing system can include an aqueous mixture of a N -oxyl compound and a hypochlorite compound. During oxidation, the pH of the aqueous mixture can be maintained at from 8.5 to 11. Cellulose products can be formed from the cellulose materials. For example, the cellulose products can be used to form a packaging material, a biomedical device or implant, a drug delivery material, a fiber, a textile material, a template for electronic components, or a separation membrane. Methods of making the cellulose product include dissolving or suspending an active ingredient in a medium comprising the cellulose material.

Flushable fibrous structure products, including sanitary tissue products, are described. As discussed in the background section, there is a relatively narrow desirable range of floatation/sink time that can be predicative of flushability success. Fibrous structures that float can have difficulty exiting a toilet bowl. And fibrous structures that sink too fast can cause a plug at the exit point of a toilet bowl. Thus, fibrous structures and sanitary tissue products comprising the same that do not float but sink sufficiently slow when placed into a toilet so as not to cause a plug are provided.
摘要:
The invention relates to preparation of paper and various products of paper from waste formed during wine making and wastes from other food processing units, like production of juice. More particularly, the present invention relates to a composition and a process for preparing paper comprising industrial waste such as cotton fabric waste and pomace in a predetermined ratio. The invention also relates to use of the compositions form making paper and/or formed packaging.
摘要:
The present invention refers to an absorbent material, such as a non-woven web or a tissue paper, comprising continuous filaments and short fibers, the short fibers comprising natural and/or synthetic fibers or staple fibers, wherein the absorbent material exhibits an absorbency speed of equal to or less than 2 s and a weight loss when washed of equal to or less than 5 %. The present invention also relates to a method for manufacturing the absorbent material and a wipe comprising the said material.

Die vorliegende Erfindung betrifft ein mehrlagiges Kartonmaterial (10) umfassend mindestens eine erste Faserstofflage (12), welche ein cellulosehaltiges Basismaterial aufweist, und mindestens eine zweite Faserstofflage (14) umfassend ein Gemisch aus cellulosehaltigem Material und Feinstoffpartikeln, wobei ein Ursprungsmaterial für die Feinstoffpartikel Kokostorf ist und die Feinstoffpartikel eine Partikelgröße
摘要:
A multi-ply absorbent product having a wet scrubbing resistance greater than 120 revolutions and a basis weight of between 30 and 50 grams per square meter. A heated adhesive is applied between two single plies / webs, the multiple plies are embossed according to particular parameters, and the embossed webs are compressed with a marrying roll. The adhesive is heated to a temperature of between approximately 32 degrees C to 66 degrees C for application between the multiple plies. For each ply, the embossed area generally occupies between approximately 5 to 15 % of the total surface area of a surface of the ply, the depth of embossment of the surface is generally between approximately 0.28 and 0.43 centimeters deep, and the embossment of the surface is generally between approximately 0.04 to 0.08 square centimeters in size.

The present invention is directed to wet wipes and methods of making thereof. In one aspect, a wet wipe includes a multi-ply tissue impregnated with a wetting composition. The multi-ply tissue includes papermaking fibers, is substantially free of synthetic fibers, and has an absorbent capacity of at least about 8 grams of the wetting composition per gram of the dry multi-ply tissue (g/g) as measured in accordance with American Society for Testing and Materials International (ASTM International) standard D4250. A single ply of the multi-ply tissue has a basis weight of at least 8 pounds per 3,000 square foot ream (lb/rm).
摘要:
The method of manufacturing cellulose nano-fibres from stalks of annual crops consist in that pieces of the stalks of annual plants are in sequence subjected to the action of steam, mechanical defibrillation, digestion in a digesting liquor, oxygen delignification in aqueous medium containing NaOH and MgSO 4 , bleaching with sodium chlorite done at least twice, alkaline extraction in an NaOH solution, enzymatic treatment of the prepared cellulose pulp by cellulase with 10-1000 J/g activity of endo-l,4-beta- glucanase 10-1000 J/g. After washing and enzyme deactivation, the aqueous suspension of the cellulose is put to homogenization and centrifugation to obtain a supernatant which contains cellulose nano-fibers.
摘要:
The present invention is directed to a method of increasing the brightness of non-wood fibers. The method comprises forming a mixture of non-wood fibers and exposing the mixture to a brightening agent, the brightening agent being a permanganate compound, an acid, or a combination of the permanganate compound and the acid. The resulting brightened fibers have a brightness greater than the fibers of the mixture before exposure as measured by MacBeth UV-C standard.
