폴리에스테르 필라먼트사의 가공 처리후의 특성변화에 관한 연구
박신웅,주강,노정익,Park, S. W.,Choo, K.,Raw, J. I. 한국섬유공학회 1975 한국섬유공학회지 Vol.12 No.1
The characteristics of five kind domestic polyester filaments have been examined with a variation of twist number and texturing temperature using FT type texturing machine. The results are as follows; 1. The concentration of dye absorption reached maximum at about 210$^{\circ}C$ of the heater temperature. 2. The necking state of textured yarns was not related with texturing conditions. 3. The fineness variations of textured yarns were increased tp 5.5∼9.4% than those of raw filament yarns, and were serious at 180$^{\circ}C$ of the heater temperature. 4. The frictional coefficient was decreased by the texturing process but there was no connection with heater temperature and twist numbers during texturing. 5. The Static electricity of textured yarns was not varied with the texturing conditions, twist numbers, and heater temperature, but static electricity was decreased slightly with the abrading numbers of yarn cohesion.

Wool/Polyester 혼방 소모사의 방적공정중 섬유절단에 관한 조사와 25tex혼방사 방출시 polyester의 혼방율이 소모사의 물리적특성에 미치는 영향을 알아보았다. 방적공정중 섬유의 절단은 주로 carding 공정에서 일어났고, 더 나가서는 gilling 공정에서도 손상을 받았음을 알았다. polyester의 함량이 증가할수록 균제도, 꼬임수 변동, 인장강도와 절단선도 및 그들의 C.V.%등은 좋아졌고, 번수변동에는 별다른 영향을 주지 않았다. Some physical properties of wool/polyester blended worsted yarns were investigated. Fiber breakage was mainly occurred from the carding process, and later on, further in the consecutive gilling performance. In the 25 tex wool/polyester blended yarn, the content of polyester fiber contributed to the evenness, C.V.% of tpcm, breaking load, elongation at break and their C.V.%. But the C.V.% of yarn count was not affected significantly by the content of those two fibers.
