Continuous filament (BCF) fiber

From:Join High (Xiamen) Fiber Tech Co., LTD     Release time:2018-08-01

Overview: Bulked continuous filament is different. Instead of creating many 7-inch or 8-inch lengths of strands, continuous filament is extruded as one long string. These strings are then twisted and heatset together to form strands of yarn. The yarn may also be texturized to curl, or kink; this also increases the bulk and gives the yarn twist more memory for better texture retention and wear resistance.

Continuous filament (BCF) fiber

Bulked continuous filament is different. Instead of creating many 7-inch or 8-inch lengths of strands, continuous filament is extruded as one long string. These strings are then twisted and heatset together to form strands of yarn. The yarn may also be texturized to curl, or kink; this also increases the bulk and gives the yarn twist more memory for better texture retention and wear resistance.

Advantages

Because BCF fiber is one continuous strand of fiber, it will not shed loose fibers like

staple fibers. It is also more cost-effective to manufacture continuous filament yarn

today, because of the fewer steps required.

Perhaps most important are advances in fiber technology, resulting in the ability to

create filament looks that were not practical in the past. Technology has also made

filament production faster and even more economical than before. Styles that were the almost exclusive domain of spun yarn can now be made with continuous filament yarn.
