Method for operating a needle loom comprising at least one needle board in which a web or lap of fibres is passed in front of the needles, said web or fibre moving in a so-called feed direction, or machine direction or MD, between two end positions in which the free ends of the needles have a zero speed, and the at least one needle board and/or needles are driven in a back-and-forth movement in a direction other than the feed direction, particularly in the perpendicular direction, or a direction that is substantially perpendicular to the plane of the lap or web, such that the free ends of the needles have, in a first interval extending in the lap or web between an outer surface of the web or lap of fibres and an end position, a first movement having a first speed profile as an absolute value for a first duration, then, in a second interval extending in the lap or web between said one end position and said one outer surface, a second movement having a second speed profile as an absolute value for a second duration, is characterised in that the maximum speed of the second profile is higher than the maximum speed of the first profile and/or the second duration is shorter than the first duration.

Textiles are re-cycled by grinding and scatter-laying onto a needle-punched web optionally containing low-melting material, followed by laying a second needle-punched web over the scattered layer and re-needling the three layers before applying heat or heat and pressure to activate the low-melting ground material present within the layers. Additional low-melt ground material is optionally blended into the ground textile if low melt components are absent or insufficient to bond the composite. The ground material is driven and dispersed into the surrounding web layers with at least part of the material being adjacent the two outer surfaces. The physical properties of the composite can be adjusted by selecting suitable combinations including but not limited to needling stroke depth, needling density, needle gage, low-melt content, heat finishing conditions, and relative layer weights. The final composites can optionally be reintroduced into the original end use and include significant percentages of recycled material.

Aspects herein are directed to a composite nonwoven textile that includes non-linear entangled seams and method and systems for producing the same. The composite nonwoven textile includes at least a first nonwoven layer, a second layer, and a fill material positioned between the first nonwoven layer and the second layer. When the composite nonwoven textile is formed into a garment, the regions between the non-linear entangled seams may help store and retain heat to provide insulation, and the non-linear entangled seams may help prevent shifting or drift of the fill material.
