The present invention relates to a crimped polyester conductive filament, a manufacturing method and an application thereof. The crimped polyester conductive filament is obtained by subjecting a polyester conductive filament to a crimping deformation process, and has a crimp shrinkage of 15%-60% and a crimp stability of 40%-90%. The process of deformation processing is as follows: the conductive fiber protofilament is heated and plasticized by a deformed hot-box, cooled by a cooling plate, twisted and untwisted by a false twister, shaped, added with interlaced nodes, oiled, wound, inspected, and packaged. The crimped polyester conductive filament is beneficial to the subsequent blended weaving, or used alone for weaving, and can exhibit a soft human experience effect, and can be widely used in smart wear and other fields.

The invention relates to modified reinforcement fibers for use in a variety of applications. The modification includes crimping linear or straight reinforcement fibers to create a deformed or different shaped reinforcement fiber. Examples of the shaped fibers resulting from crimping include w-shaped, s-shaped, z-shaped and wedge-shaped.

The present invention relates to a crimped polyamide conductive filament, a manufacturing method and an application thereof. The crimped polyamide conductive filament is obtained by subjecting a conductive fiber with composite structure prepared by melt composite spinning process to a crimping deformation process, and has a crimp shrinkage of 15%-60% and a crimp stability of 40%-90%. The process of deformation processing is as follows: the conductive fiber protofilament is heated and plasticized by a deformed hot-box, cooled by a cooling plate, twisted and untwisted by a false twister, shaped, added with interlaced nodes, oiled, wound, inspected, and packaged. The crimped polyamide conductive filament is beneficial to the subsequent blended weaving, or used alone for weaving, and can exhibit a soft human experience effect, and can be widely used in intelligent sensing, smart wear and other fields.

The invention is contemplated for providing polyethylene-based fibers in which elution of metal from polyethylene is suppressed as much as possible. The invention relates to polyethylene-based fibers, composed of at least one kind of polyethylene resin, in which a total of content of metal elements such as Na, K, Ca, Fe, Cu, Mg, Mn, Li, Al, Cr, Ni and Zn contained inside the fibers is 40 ppm or less. Moreover, the invention relates to a nonwoven fabric using the polyethylene-based fibers.

A method for preparing a simulated lawn is provided, which comprises wiredrawing, coiling, weaving and post-processing raw materials, to obtain a simulated lawn product, wherein the weaving is straight yarn-curled yarn-interlacing weaving, in which one line of curled yarn is weaved between two adjacent straight yarns, and spacing between adjacent straight yarns is to inches and knitting needle number is 150 to 350 needles/meter.
