Abstract
1,104,694. Making fibrillated monofilaments. BAKELITE XYLONITE Ltd. 8 June, 1965 [6 March, 1964], No. 9530/64. Heading B5B. Fibrillated monofilaments are made by treating with an agent which selectively acts on one of the polymer phases of the monofilament an oriented monofilament comprising an intimate mixture of two or more polymers of which two or more of the polymers are incompatible with one another in the proportion present in the mixture, flexing the treated filament (particularly by crimping it by a mechanical process), and if necessary, removing the agent. The effect of treating the monofilament with the selective agent is to cause the monofilament to be more easily fibrillated after it has been flexed. The action of the agent on the monofilament may result in at least one but not all of the polymer phase of the monofilament (said phase consisting of one or more polymers) becoming relatively soft, flexible, waxy or liquid, while the other component of the monofilament (which component consists of one or more polymers incompatible with the first component) remains unaffected or relatively unaffected by the treatment or relatively rigid. When one of these components is nylon, a liquid ketone such as acetone may be used. Two polymers are defined as being mutually incompatible if, when mixed in the proportions in which they are present in the monofilament and at a temperature at which they are both in a soft plastic or liquid condition, they do not form a homogeneous mixture and are not mutually soluble. The selective softening of the filament may be effected as follows: (1) by immersing the filament in a solvent which dissolves one component of the filament and not the other, the time of immersion being only sufficient to soften the soluble component; (2) by heating the filament to a temperature at which one component of the filament is softer than the other; (3) by treating the filament with a chemical reagent which makes one component harder or softer than the other (e.g. a cross-linking agent or a plasticizer respectively). The monofilaments may be produced by melt-spinning the following polymer mixtures: (1) polystyrene and polyethylene oxide; (2) polystyrene, styrene/ acrylonitrile copolymer and polyethylene oxide; (3) polyethylene and polyethylene oxide; (4) nylon type 6 and low molecular weight polyethylene; (5) nylon type 6 and a low molecular weight polymer of #-pinene; (6) high density polyethylene and cellulose acetate; (7) isotactic polypropylene and cellulose acetate; (8) polypropylene and low molecular weight polystyrene; (9) polypropylene and polyethylene oxide.
