| Summary: | 碩士 === 亞東技術學院 === 纖維與材料應用產業研發碩士專班 === 100 === This research utilized conjugate melting spinning technology to prepare side by side composite fibers. The fibers were made in the same process condition and the fixed take-up speed, by changing the draws ratio and control the different component proportions the side by side composite fibers were made and the properties were discussed.
Using four types of Nylon 6 polymers as raw material, such as is Full Dull Polyamide 6(FD-PA6), Bright Polyamide 6(BR-PA6), Semi Dull Hydrophilic Monomer Polyamide 6(HM-PA6) and Bright Cationic Dyeable Polyamide 6(CD-PA6). The three kinds of side by side composite fibers were then produced as FD-PA6/BR-PA6, FD-PA6/HM-PA6 and FD-PA6/CD-PA6.
The experimental results showed that the composite fiber in the draw ratio of 3.2 and FD-PA6 fiber composite ratio of 30%, reached the higher fiber crimp rate, tenacity and boiling water shrinkage. FD-PA6/BR-PA6 composite fiber in the draw ratio of 3.2, reached the highest fiber strength of 4.62 g/d. Moreover, FD-PA6/CD-PA6 composite fiber in the draw ratio of 3.2 and CD-PA6 fiber composite ratio of 30%, could be reached the highest crimp rate of 12.2%.
