Abstract
909,940. Crimping thermoplastic filaments. EASTMAN KODAK CO. Nov. 21, 1958 [Nov. 27, 1957 (2); Aug. 28, 1958], No. 37482/58. Class 15(2). [Also in Group IX] Uniformly crimped tow is made by spinning continuous thermoplasfic filaments of a denier not greater than 16 per filament, gathering the filaments together to form a band of substantially uniform width and thickness and a total denier not greater than 160,000, imparting to the band a crimp not less than 8 crimps per inch, and applying to the filaments at a stage before the crimping operation a non-toxic lubricant comprising an emulsion containing at least one sorbitan compound. Suitable sorbitan compounds are the monolaurate, mono oleate, monopalmitate, and polyoxyethylene sorbitan mono-oleate or laurate; the emulsion is an aqueous one with white mineral oil or polyoxyethylene castor-oil derivative applied by a ceramic or metal roller which may be roughened or provided with a groove in which the filaments travel, and the amount applied may be controlled by a doctor-blade, by arranging the roller to deflect the path of the filaments through an arc which is varied as required, or by varying the speed of the roller, which may rotate oppositely to the direction of travel of the filaments. The emulsion may also be applied by a wick or surface to which the supply may be metered.
