Abstract
To analyse basic properties for making packing batt according to doubling condition, packing batt yarn, of 300D,900D, 3600D made from DTY yarn 150D/48 were produced from KTDI. The results are as follows: The birefringence ofdecreased with increasing the annealing temperature and denier. The higher than annealing temperature of 160oC, initialmodulus of the sample are equilibrated. The strain recovery ratio of samples decreased with increasing the annealing tem-perature and denier. The lower than annealing temperature of 140oC, strain recovery ratio of the sample are decreasedWhere the 900D, 3600Dyarns are at 100oC the specific bending rigidity value obtained is 0.65kgf/d but the twisted yarn(3,600) obtained 0.006 (gfcm2/tex2). However, where the heat temperature is 160oC, specific bending rigidity valueobtained 0.003(gfcm2/tex2).
