A wrinkled filament nonwoven fabric according to the present invention has a structure in which thermoplastic resin filaments are arrayed lengthwise and crosswise, and includes a plurality of first wrinkles arranged in parallel and a plurality of second wrinkles arranged in parallel, each of the plurality of second wrinkles intersecting at least one of the plurality of first wrinkles. Continuous production of the wrinkled filament nonwoven fabric according to the present invention is relatively easy.

A folded fabric crushing machine that makes it possible to produce curtain fabric, which is used in the production of multi-layered woven curtains used by connecting on fixed, movable or folding windows, doors and glass balconies, produced by multi-layered fabric weaving technique, without using adhesive material.

A preparation method of a composite non-woven fabric by pleating to enhance stretchability, includes unwinding an upper layer of non-woven fabric and a stretch film, and adjusting them in position; pleating the adjusted upper layer of non-woven fabric along a cross direction (CD) or machine direction (MD) through an upper pleating mechanism, and aligning the pleated upper layer of non-woven fabric with the stretch film; feeding the upper layer of non-woven fabric and the stretch film aligned with each other into a first laminating device, and laminating a contact surface between the bottom of the pleat and the stretch film to obtain a double-layer stretch non-woven fabric material; and rewinding the laminated stretch material after tension adjustment and alignment. The method produces not only a CD- or MD-stretch material but also a four-way stretch material; by adding a pleated design to the non-woven fabric.

An adaptive fabric folding system and methods for folding a subject fabric article are provided. The system includes a turnover device; a fold line adjuster configured to adjust a fold line of the subject fabric article; a pleat generator; and a fold line fixing device. The pleat generator includes an adjustor adjusting a width of a pleat of the subject fabric article and a fabric feeding device. The turnover device is configured to flip a margin of the subject fabric article delimited by a preset fold line. The fold line adjuster is configured such that a lateral movement of the guiding portion changes a width of margin of the subject fabric article that engages with a curved surface of the turnover device to alter the fold line. The pleat generator is configured to create and regulate widths of pleats while moving the subject fabric article.
