Abstract
The present disclosure relates to a hybrid fiber fabricated with a low production cost while having excellent mechanical properties, as well as a method for fabricating the same. The disclosed hybrid fiber includes; a first filament, and a second filament different from the first filament, wherein a strength-strain curve of the hybrid fiber measured according to ASTM D 885 has at least one peak, provided that, if the strength-strain curve has at least two or more peaks, a difference in strain between a first peak having the lowest strain and a second peak having the highest strain, among the above two or more peaks, is 3% or less.
Claims20
A hybrid fiber, comprising:
- a first filament;
- and
- a second filament different from the first filament, wherein a strength-strain curve of the hybrid fiber measured according to ASTM D 885 regulation has at least one peak, provided that, if the strength-strain curve has at least two or more peaks, a difference in strain between a first peak having the lowest strain and a second peak having the highest strain, among the above two or more peaks, is 3% or less.
A method for fabricating a hybrid fiber, comprising:
- preparing a first filament;
- preparing a second filament having higher strain than that of the first filament;
- applying tension to the second filament, to maintain a difference in strain between the first and second filaments to 3% or less;
- and
- combining the first and second filaments having a difference in strain of 3% or less.
A method for fabricating a hybrid fiber, comprising:
- preparing a first filament;
- preparing a second filament having higher strain than that of the first filament;
- and
- combining the first and second filaments, wherein a length of the first filament is longer than that of the second filament.
A method for fabricating a hybrid fiber, comprising:
- preparing a first filament;
- preparing a second filament having higher strain than that of the first filament;
- primarily twisting the first filament at a first twist number to form a first primary twisted yarn;
- primarily twisting the second filament at a second twist number less than the first twist number, to form a second primary twisted yarn;
- and
- secondarily twisting the first and second primary twisted yarns.
