Abstract

<PICT:0812110/IV (a)/1> <PICT:0812110/IV (a)/2> A polyethylene terephthalate filament (as defined below) has sharply defined alternate smaller and larger denier segments, the smaller denier segments being from about 0.1 to about 1.5 inches long, the larger denier segments from about 0.015 to about 0.15 inch long, and the smaller denier segments being longer than the larger denier segments. The term "polyethylene terephthalate" is taken to include copolyesters containing residues of other dicarboxylic acids, e.g. sebacic, isophthalic or sodium sulphoisophthalic acid, or other glycols, e.g. butylene glycol, in amounts up to about 20 mol. per cent, and includes also terephthalate polyesters of and glycol of the formula HO(CH2)nOH, where n is 2-10 inclusive. Such filaments may be made by heating alternate sections of an undrawn, continuous filament, yarn and then drawing the non-uniformly heated yarn until the heated sections are from about 0.1 to about 1.5 inches long, and the unheated sections are from about 0.015 to about 0.15 inch long. In Fig. 1, the yarn 1 passes around guide pin 2 and between rotating rolls 3, 4 to a heated grooved roll 7, which heats alternate sections of yarn, and thence to roll 6, which has a higher peripheral speed than roll 5, thus stretching the heated sections of yarn, which, on leaving this roll, has the form shown in Fig. 2. In the yarn produced the smaller denier segments of each filament may be substantially crystalline, and the ratio of the diameter of the larger denier segments to the diameter of the smaller denier segments may be between about 1.3 and about 2.0. The preferred temperature range for the heat-treatment is between about 90 DEG and 115 DEG C. Filaments in which both smaller and larger denier segments are substantially crystalline may be produced by a subsequent heat-treatment which is preferably applied to a fabric woven or knitted from yarns of the above filaments. In this process the fabric is heated to between about 90 DEG and 200 DEG C. for between about 30 mins. and 10 secs., as for example at 90 DEG C. or above in water, or with dry heat between about 125 DEG and 200 DEG C. The fabric so made has a dry crepe-like handle, and may be dyed at a temperature of at least 90 DEG C. to give a fabric having a speckled appearance.
