Title: New forms of man-made fibres and methods for their production
Inventor: MAREK BRUNO STEFAN VLADIMIR
IPC: D06Q1/02
Filed: 1961-08-29
Abstract: 951,131. Treating synthetic fibres. SOC. DE LA VISCOSE SUISSE. June 15, 1962 [Aug. 29, 1961], No. 31133/61. Heading B5B. [Also in Division D2] Synthetic fibres with fine, hook-like filaments extending from the main fibre stem, are made by subjecting the fibres, in the form of a suspension in a liquid medium containing 3 to 13% by weight of fibres, to a vigorous mechanical movement in the presence of a swelling agent. The resulting fibres can be beaten, have a considerably increased water holding capacity, and are capable of felting and interlocking with each other and with other fibres to form coherent, self-supporting waterleaves suitable for processing on paper machines. The hook-like filaments, from whence the treated fibres obtain their interlocking capacity, cover the surface of the fibres and are usually one-half to twice the diameter of the fibres in length (Fig. 4). The fibres processed are suitably 1 mm.-10 mmin length, may be of any titre, and may be of any form, e.g. monofilaments, or hollow or ribbonlike structures. Specified fibres are regenerated cellulose, e.g. viscose, cellulose esters, e.g. cellulose triacetate, polyamides, e.g. polyhexamethylene adipamide, polyesters, e.g. polyethylene terephthalate, polyacrylonitrile, polycaprolactam, and copolymers and graft polymers of these substances. The swelling agent varies according to the fibre, and may be e.g. 13% hydrochloric acid, 4% aqueous sodium hydroxide, 60% acetic acid, a mixture of 68% formic acid, 12% anhydrous sodium sulphate and 20% water, a mixture of 2% hydrochloric acid, 40% acetic acid and 58% water, a mixture of 23% phenol and 77% monochlorobenzene, and a mixture of 40% benzyl alcohol and 60% propylene carbonate. The vigorous movement of the fibres may be produced by, e.g., a stirrer, high-speed mixer, electromagnetic vibrator or ultrasonic apparatus. The time of treatment is usually 30-100 minutes using a stirrer or 5-15 minutes using ultrasonic apparatus. The temperature may vary from 5-10‹ C. (for regenerated cellulose fibres) to 70-80‹ C. (for polyacrylonitrile). After washing to remove swelling agent and, if added, wetting or lubricating agent, the hooked fibres may be taken up in neutral, slightly acid or slightly alkaline solution, and beaten for 1-2 hours in a hollander or refiner. For the production of sheet-like structures, a sizing material may be added to an aqueous suspension of beaten or unbeaten hooked fibres, which are collected on a wire screen. The wet waterleaves, with or without the addition of binders, are pressed at high temperatures. It is possible to mix hooked fibres with untreated synthetic fibres and with natural cellulose so as to give, depending on the type and proportions of fibres, sheets with textile-like or paper-like character. The fibres may also be used for the manufacture of filling materials and felts. Specifications 687,041, 810,001, 865,707, 868,651, French Specifications 1,245,863, 1,268,034 and U.S.A.
