Abstract:
Aluminium-salt-impregnated fibres, preferably in the form of fluff, for use in absorption articles, such as diapers, incontinence guards, etc., which exhibit high aluminium contents and increased absorption rates and improved dispersion of liquid in horizontal and vertical directions in a layer comprising the fibres. The fibres, in the form of an aqueous suspension, are impregnated with aluminium salt in aqueous solution at a pH of 5-11, preferably 8.5-9.5, particularly at pH = 9, optionally in the presence of silicate.
Abstract:
A method of producing mechanical and chemi-mechanical pulp with a yield above 85 % from lignocellulose-containing material for the manufacture of paper or board products. The material is subjected to mechanical processing in at least two steps. The material at its feed into the first step has a temperature below the softening temperature of lignin. When the material is fed into at least one subsequent processing step, it shall have a temperature above the softening temperature of lignin.
Abstract:
A fibrous structure notably for use in hygienic articles such as diapers, sanitary napkins, incontinence guards, wipes and the like, having one or several types of polar, silicon containing compounds bound to at least one portion of the surface of the fibrous structure by interaction between the surface and the silicon containing compounds, whereby the fibrous structure exhibits a predetermined degree of hydrophilicity and adhesion properties which are substantially unaffected by wetting of the fibrous structure. Further, the invention pertains to absorbent, hygienic and textile articles comprising such a fibrous structure.
Abstract:
Fibres which have an increased specific surface area and improved absorption properties, preferably intended for use in the form of fluff pulp in absorption articles such as diapers, incontinence guards, etc., in which the fibres present a porous layer of hydrophilic chemicals anchored on the fibre surface; a method of producing such fibres, their use in absorption articles and an absorption material which includes the fibres.
Abstract:
Method of producing a particle or group of particles having a coating of at least two, preferably at least three, outside each other located thin layers of interacting polymers, at which the particle or group of particles is treated in consecutive steps with solutions of the interacting polymers. Excess of the previous polymer is removed between each treatment step alternatively the respective polymer is added only in such an amount in each step that substantially all polymer is absorbed to the particle surface. It is also referred to a paper- or nonwoven product containing fibers and/or fillers containing particles or groups of particles of the mentioned kind.
