摘要： An amino-aldehyde, eg urea-formaldehyde, resin is converted into fibres and used to form at least 1% by weight of the fibrous component of paper. The resin fibres, which are free of bound inorganic oxyacid radicals and carbohydrate, have a degree of cure of between 50 and 90%. The use of such partially cured resin fibres gives an improvement in the strength of the paper.

摘要： An absorbent paper is formed from 5-95 % by weight of insoluble amino-formaldehyde resin fibres of 1-10 mm length and 1-30 µm diameter and correspondingly 95-5 % cellulose pulp. Where the Canadian Standard Freeness of the cellulose pulp is below 310 x + 140 ml. (where x is the proportion of lignin free pulp in the cellulose pulp) the proportion of amino-formaldehyde fibres is such that the blend has a freeness above 220 x + 400 ml.
The paper may be made by forming an aqueous slurry of the fibrous constituents into sheet form followed by dewatering.摘要翻译： 吸收纸由5-95重量％的1-10毫米长的不溶性氨基甲醛树脂纤维和1-30μm直径以及相应的95-5％纤维素纸浆形成。 加拿大标准的游离度在310 x + 140 ml以下的纤维素纸浆。 （其中x是纤维素纸浆中不含木素的纸浆的比例），氨基 - 甲醛纤维的比例使得该共混物的游离度高于220×+ 400ml。 可以通过将纤维成分的水性浆料形成片状形式然后脱水来制造纸。

摘要： Hydrophilic polyolefin fibers are prepared by treating an anionic fibrous polyolefin composition containing carboxylic functionality with an aqueous admixture of selected cationic and anionic water-soluble, nitrogen-containing polymers. The anionic polyolefin composition may, for example, be a pololefin containing carboxyl groups which have been introduced into the polymer molecule by grafting the polyolefin with a monomer-containing carboxylic functionality or by oxidizing the polyolefin with oxygen or ozone or the composition may be a polyolefin in admixture with an anionic polymer containing carboxylic functionality.
Blends of the hydrophilic fibers with wood pulp provide paper products having improved physical properties.
