Abstract

1,103,317. Making polyamide composite filaments. FARBENFABRIKEN BAYER A.G. 13 May, 1965 [15 May, 1964; 7 Jan., 1965], No. 20267/65. Heading B5B. Crimped conjugate bicomponent polyamide filaments consisting of two components which are bonded together along the whole length of the filament in side-by-side relationship are produced by melt-spinning a modified polyamide containing 0À5 to 20% of a modifying sulphonic acid segment having the general formula wherein R<SP>11</SP> is a -(CH 2 ) x - group, x and y each represent an integer from 2 to 12, R and R<SP>1</SP> each represent a hydrogen atom or a group -(CH 2 ) z -SO 3 Me, in which z represents an integer from 4 to 6 and Me represents an alkali metal or hydrogen, the group -(CH 2 ) z -SO 3 Me, being present at least once in the segment, and a polyamide which does not contain sulphonic acid groups, the two types of polyamide being extruded into air through a common spinneret orifice to form the composite filament at a temperature between 250‹ and 300‹ C., the filament thus formed being stretched at room temperature or at a higher temperature and treated with water at a temperature between 60‹ and 120‹ C. The process may be modified in that the symbol R<SP>11</SP> in the above general formula represents a cyclohexylene group or a group having the formula The ratios by weight between the two components of the composite filaments are advantageously between 5: 1 and 1: 5. The stretching step may be effected at a temperature between 20‹ and 140‹ C. In an example, an unmodified poly-#-aminocaproic acid and a modified poly-#- aminocaproic acid containing 5% by weight of the structural unit are simultaneously melt spun at 280‹ C. into air at 25‹ C. in such a manner that the rates of supply by weight of the polymers to each of the orifices of the spinneret are equal, the composite filaments thus produced are stretched at a stretch ratio of 3À5: 1 at 80‹ C. and thereafter treated with water at 90‹ C. and dried while in the relaxed state.
