Recycling of cellulosic textiles

A method for recycling textiles comprising cellulose with the following steps of: optionally disintegrating the textile, Swelling the cellulose, under reducing conditions, wherein at least one reducing agent is present at least during a part of the swelling, and then performing at least one of the following two bleaching steps in any order: i) bleaching the material with oxygen at alkaline conditions with a pH in the range 9-13.5, and ii) bleaching the material with ozone at acid conditions below pH 6. An advantage is that the yield is improved at the same time as excellent decolourization is achieved. If the recycled material is used in viscose manufacture, the risk of clogging nozzles and so on is reduced.

FINE FIBROUS CELLULOSE, DISPERSED SOLUTION, SHEET, LAMINATED SHEET, LAMINATE, AND METHOD FOR PRODUCING FINE FIBROUS CELLULOSE

It is an object of the present invention to provide fine fibrous cellulose capable of enhancing transparency and suppressing coloring, when the fine fibrous cellulose are processed into a dispersed solution or a sheet. The present invention relates to fine fibrous cellulose, in which the amount of substituents introduced is less than 0.5 mmol/g and the fiber width is 1 to 10 nm. Moreover, the present invention relates to a dispersed solution and a sheet, each of which comprises fine fibrous cellulose. Furthermore, the present invention relates to a method for producing fine fibrous cellulose, comprising: (A) removing at least a part of substituents from fine fibrous cellulose with a fiber width of 1000 nm or less having the substituents, and (B) performing a uniform dispersion treatment on the resulting fine fibrous cellulose after completion of the (A).

A fat-binding composition contains an inclusion complex with a host molecule and a guest molecule. The guest molecule includes one or more amino acids, vitamins, flavorants or related compounds, rutin, betanin, derivatives thereof, and mixtures thereof. The fat-binding composition may be in the form of a tablet or powder, for example, and may be incorporated into a food or beverage product. If in the form of a powder or tablet, the composition may optionally contain a carbonation-forming component and may be dissolved in carbonated or non-carbonated water. The fat-binding composition may also be employed in a method for binding fat ingested by an animal which includes having the animal ingest the composition, or a food or beverage product containing the same.

METHOD FOR PRODUCING A VISCOSE SOLUTION AND A VISCOSE SOLUTION PRODUCED THEREBY AND A METHOD FOR PRODUCING VISCOSE FIBER
20220119554 · 2022-04-21 ·

Described herein is a method for producing a viscose solution including a step of adding alkyl polyglycoside (APG) prior to and/or during xanthation of alkali cellulose. When APG is added prior to or during xanthation of alkali cellulose, the reactivity between alkali cellulose and CS.sub.2 could be increased and the xanthation could be accelerated, as a result of which formation of agglomerates and/or lumps in the obtained viscose solution and then the obtained viscose fiber spun therefrom is significantly reduced, relative to the situation when conventional surfactants such as phenyl ethoxylate are added likewise. Also described herein is a viscose solution obtained by the foresaid method, and a method for producing viscose fiber with the foresaid viscose solution or including the foresaid method.

THE USE OF ETHOXYLATED FATTY AMIDO ALCOHOLS AS A REACTIVITY ADDITIVE IN THE PROCESS WHEREIN CELLULOSE IS REACTED WITH LYE
20210347917 · 2021-11-11 · ·

The present disclosure relates to the use of alkoxylated fatty amido alcohols in the process to make viscose wherein cellulose is reacted with lye and the lye strength is from about 8 to about 20% by weight of NaOH, based on the weight of water in the reaction mixture. The use as a reaction improvement additive improves the reaction rate between the cellulose and the lye. The use also improves the reaction between alkali-cellulose and CS.sub.2. The present disclosure also relates to solid cellulose that is treated with one or more ethoxylated fatty amido alcohols and which is suitable for use in the claimed process.
