Definitions
- fluff highly absorbent cellulose
- T o be suitable for fluif, the pulp should be of such a texture that the fibres can be sepa rated from each other without being shortened to any noticeable extent, and it should be possible to carry out the separation of fibres at a low consumption of energy.
- the fluff obtained should exhibit properties being of decisive importance to its use in hygienic products, for which it is intended, such as high bulk, good elasticity, great absorption capacity and absorption rate.
- this charge fixes an immovable and sharply defined layer having a positive charge, and said positive layer induces, in turn, in the water outside it a diffuse, negatively charged layer which is movable and moves with the water, if the latter is caused to flow.
- the difference in potential between said diffuse charge layer and the main mass of the suspension water has been designated as Z-potential and can be determined by means of electrokinetical measuring methods.
- the Z-potential which has the same character as the charge of the fibre surface, grows and diminishes numerically with the charge, when the latter is changed by charged particles (ions) supplied 3,677,886 Patented July 18, 1972 from outside.
- the Z-potential and the fibre charge reach the value zero simultaneously, and thus the Z-potential gives a valuable indication of the state of charge of the fibre.
- the new method consists in that two different-kinds of substances are added to a pulp immediately before or on the wet machine, Whereupon the pulp is dried and the dried pulp is defibrated in a manner known per se.
- One of these substances is a nonionic or anionic, finely dispersed, high-molecular, organic substance having a molecular structure containing hydrophobic parts, and the other substance is a cationic retention agent which is added in such an amount that the Z-potential of the pulp approaches zero.
- the retention agent changes the state of charge of the fibres, so that the fibres are capable of retaining nonionic and anionic substances on their surfaces.
- the Z-potential may be determined by an electrokinetical measurement as known per se. 7
- a number of substances are known as retention agents in other connections.
- retention agents are several metal salts with polyvalent cations, such as Al, Ce La, Th Zr certain finely di-vided minerals such as chrysotil asbestos and certain nitrogenous organic substances such as alkyl amines, al'kyl diamines, polyimines, alkoxylated derivatives thereof, and others.
- Example 1 A nonionic (neutral) parafiine emulsion (Mobilcer HM) containing 0.4 g. of paratiine was added, while agitating, to 5 liters aqueous suspension of a bleached pine sulphate pulp (2% concentration). After 10 minutes and while continuing the agitation, an aluminum sulphate solution (10 g. of Al (SO per liter) was added in portions, until a sample withdrawn showed that the Z-potential had assumed the value zero. For that 50 ml. of aluminum sulphate solution was needed, i.e. 0.5% Al-sulphate, calculated on the weight of the dry pulp. The Z-potential was determined by means of a Streaming Current Detector made by Waters Associate Inc., Framingham, Mass, U.S.A.
- the pulp suspension was drained on a suction filter to form a number of fibre sheets containing about 700 g. of dry pulp per sq. In.
- the sheets were drained by pressing to a dry content of 35% and were then dried to 93% dry content.
- From another batch of the same bleached su1- phate pulp without added chemicals fibre sheets were formed in the same way and dried to 93% dry content.
- Both kinds of fibre sheets were dry defibrated in a laboratory shredder equipped with means for measuring the consumption of energy during the dry defibration. In the following table the consumption of energy and the bulk of the flutf obtained are compared.
- Example 2 While agitating, 0.06 g. of the retention agent Diaminacetat BG (Liljeholmens Stearinfabriks AB) was added to liters aqueous suspension of bleached sulphite pulp (2% concentration), and after minutes 0.45 g. of Tergitol Anionic 4 (sodium tetradecyl sulfate, produced by Union Carbide Corp.) was added, while continuing the agitation. Previously it had been ascertained by a preliminary test that the Z-potential zero was reached when adding 0.06% of the retention agent, calculated on the weight of the dry pulp.
- Example 3 In the pulp vat of the pulp mill immediately before the wet machine, there was added to a bleached sulphate pulp of 2% concentration 0.4%, calculated on the weight of dry pulp, of nonyl-phenoxy-polyglycol ether (Berol EMU-04) emulsified in water, and 0.05% (calculated on the weight of dry pulp) of a retention agent consisting of an ethoxylated alkyl amine (Berol EMU-302). On the basis of Z-potential determinations in reference samples the amount of amine had been determined such that the Z-potential of the pulp was zero.
- a bleached sulphate pulp 2% concentration 0.4%, calculated on the weight of dry pulp, of nonyl-phenoxy-polyglycol ether (Berol EMU-04) emulsified in water, and 0.05% (calculated on the weight of dry pulp) of a retention agent consisting of an ethoxylated alkyl amine (Berol EMU-302).
- a method of producing highly absorbent cellulose in the form of a fluff comprising adding to a pulp, immediately before or on the wet machine, a finely dispersed high molecular Weight substance containing hydrophobic parts and selected irom the group consisting of an organic anionic agent and an organic nonionic agent, in an amount of ODS-5%, calculated on the dry weight of the pulp, and a cationic retention agent consisting of a water soluble salt of a polyvalent metal selected from the group consisting of A1 Ce, Th, Zr and Let in an amount of 0.01-5% of the anhydrous salt thereof, calculated on the dry weight of the pulp, while regulating the amount of the added cationic substance in such a way that the Z-potential of the pulp approaches zero, drying the pulp, and then defibrating the dry pulp.
- a method of producing highly absorbent cellulose in the form of a fluff comprising adding to a pulp, immediately before or on the wet machine, finely dispersed sodium tetradecyl sulfate in an amount of ODS-5%, calculated on the dry weight of the pulp, and a cationic retention agent consisting of diamine acetate, in an amount of 0.014110%, calculated on the dry weight of the pulp, while regulating the amount of the added cationic substance in such a way that the Z-potential of the pulp approaches zero, drying the pulp, and then defibrating the dry pulp.
- a method of producing highly absorbent cellulose in the form of a fluif comprising adding to a pulp, immediately before or on the wet machine, a finely dispersed nonylphenoxy polyglycol ether in an amount of 0.0S5%, calculated on the dry weight of the pulpand a cationic retention agent consisting of an ethoxylated alkyl amine in an amount of 0.010.10%, calculated on the dry weight of the pulp, while regulating the amount of the added cationic substance in such a way, that the Z-potential of the pulp approaches zero, drying the pulp, and then defibrating the dry pulp.
