| Abstract: | The process of direct melt spinning of PET/PA6 splitable composite microfiber was studiedThe results showed that when the specification of PET/PA composite microfiber was 290 dtex/72 F,the mass ratio of PET to PA6 was 82∶18,the melt temperature of PET was 285~290℃,the spinning temperature of PA6 was 270~274℃,the spinning speed was 3000~3300 m/min,the cooling air temperature was 20~22℃,the cooling air speed was 0.45~0.60 m/min After the PET/PA6 splitable composite microfiber POY was made,the production spinnability、section shape、composite stripping effect and processing performance was wellThe breaking strength was 2.6 cn/dtex,the elongation at break was 136%,and the CV value was 0.6%. |
