摘要:
The present invention relates to a method for manufacturing a foam-formed cellulosic fibre-material. The invention further relates to retention systems and the use of such retention systems. Furthermore, the invention relates to a foam-formed cellulosic fibre-material, a cellulose bulk sheet for a packaging material and a laminated packaging material comprising the foam-formed cellulosic fibre-material.
摘要:
Fabrics comprising regenerated cellulose fibers and a nanoparticle dispersed throughout the fabric are disclosed herein. The regenerated cellulose fibers can be derived from a biomass such as a fibrous cellulose, wood pulp, cotton, paper, bast fiber, bagasse, or a combination thereof. The nanoparticle included in the fabric can be chosen to confer a desirable property, such as a thermal insulating property, to the fabric. Methods of making the fabrics comprising the regenerated cellulose fibers and nanoparticle are also provided. The method can include (a) at least partially dissolving a cellulose substrate in a medium comprising one or more ionic liquids; and dissolving or suspending a nanoparticle in the medium; (b) recovering a solid nanoparticle-modified regenerated cellulose material comprising the cellulose substrate and the nanoparticle; and (c) processing the solid nanoparticle-modified regenerated cellulose material to form the fabric.

摘要:
Provided herein is an aqueous polymer dispersion (A) obtainable by free radical emulsion copolymerizing a first ethylenically unsaturated monomer blend comprising (b) 15 to 100 % by weight of at least one Cl-C4-alkyl (meth)acrylate, in the presence of a water-soluble redox system comprising a first free radical initiator for the free radical emulsion copolymerization and an aqueous prepolymer composition (B) obtainable by free radical emulsion copolymerizing in a polymerization solvent comprising Cl-6-carboxylic acid and Cl-6-carboxylic acid anhydride a second ethylenically unsaturated monomer blend comprising (i) 5 to 50 % by weight of at least one ethylenically unsaturated quaternary amine selected from quaternary salt of N,N,N-tri(Cl-4-alkyl) amino Cl-4-alkyl(meth)acrylate with a mineral acid or an organic acid and/or quaternary salt of N,N,N-tri(Cl-4-alkyl)amino Cl-4-alkyl(meth)acrylamide with a mineral acid or an organic acid, and (iii) 10 to 95 % by weight of at least one optionally substituted styrene, in the presence of a second free radical initiator, and adding water to the obtained polymer dispersion to obtain the aqueous prepolymer composition.
摘要:
The present invention relates to a sizing agent composition comprising starch, lignosulfonate and poly(alkyl acrylate), poly(alkyl (meth)acrylate), a mixture of poly(alkyl acrylate) and poly(alkyl methacrylate) or a copolymer of alkyl acry- late and alkyl (meth)acrylate. The present invention further relates to a method for preparing the sizing agent composition, and use of the sizing agent compo- sition for sizing paper, paper products or board.
摘要:
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.

Coating compositions that can provide grease and oil resistant coating for substrates, especially paper and textile substrates, are disclosed. The coating compositions comprise water insoluble α-(1,3→glucan) polymer and/or dextran polymer and optionally other additives.
摘要:
A towel or wipe including a fibre web having a first face and an opposing second face. A coating of material is provided on fibres of the fibre web to form a layer at the first face. The material may be liquid repellent and/or a barrier to liquid vapour or liquids, so as to prevent the first face from becoming wet and/or preventing evaporation of liquid vapour.
摘要:
The present invention concerns combinations of a water repellent alkyl ketene dimer as a component (I) and a water repellent metal alcoholate as a component (II) that are strongly synergistic in repelling water from water absorbing surfaces, resulting in a surprisingly long water droplet absorption time. The combinations of the invention can be applied to the surface of any material that has water absorbing properties such as, but not limited to, wood, woven and non-woven sheeting materials, paper, building materials, gypsum board, and leather.
