A seat back for an office chair includes a knit material for extending over a structural frame. The knit material can be formed in a single knitting operation to include cushioning characteristics that vary across different regions of the knit material. The knit material may be a weft knit material having a first layer, a second layer, and a third layer, wherein the third layer is inlayed between the first and second layers and the inlay material is different from at least the first and second layers and provides a degree of cushioning between the first and second layers. The first and second layers are knit according to a predetermined pattern, the predetermined pattern determining crossing lines where the first and second layers cross one another and fix the third layer in position with respect to the first and second layers. The predetermined pattern is differentiated between regions of the back support, such that a first region of the back support has a higher density of crossing lines than a second region of the back support, the first region providing a different degree of cushioning than the second region.

A cover material for a vehicle seat provides favorable touch while utilizing the texture of a leather material. A cover material for a vehicle seat includes: a leather portion made of natural leather or artificial leather; and a mesh fabric portion bonded to the back side of the leather portion.

A method of manufacturing a suspension member including providing a first set of yarns and a second set of yarns, combining the first set of yarns and the second set of yarns to form the suspension member, and at least partially bonding a portion of the first set of yarns and the second set of yarns together by heating the suspension member to form a first zone of the suspension member having a first tension.

A spacing knitted fabric has a first and a second flat knitted fabric layer that are connected to each other by incorporated spacing threads. The first knitted fabric layer has mesh-forming loop threads made from thermoplastic plastic and non-mesh-forming additional threads made of thermoplastic plastic. In the first knitted fabric layer, only the additional threads are at least partially melted and due to the at least partial melting, causing a reinforcement of the first knitted fabric layer.

Embodiments disclosed herein provide approaches for attaching scan control and other electronic chips to textiles, e.g., on a loom as part of a real-time manufacturing process.

A method produces a seat cover for a vehicle seat made of a form-fit knit part. The form-fit knit part has continuous fibers and reinforcing fibers, and each of the reinforcing fibers is made of a core fiber and a cladding fiber coaxially sheathing the core fiber. The form-fit knit part is first produced using a knitting machine, and the seat cover is subsequently produced from the form-fit knit part using an ironing machine. The ironing machine has at least one lower mold in the shape of the vehicle seat, and the core fiber has a higher melting point than the cladding fiber.

A mattress cleaning system receives a mattress in a tank of wash liquid so that the mattress is fully submerged. A pressure applicator, for example a mechanical structure or a jetted flow of wash fluid, applies a cyclical compressive force to the sleeping surface of the mattress while the mattress is fully submerged so as to cause flushing of the wash liquid outwardly of the mattress through at least the sleeping surface of the mattress. When using a barrier to isolate one of the surfaces of the mattress on a first side of the barrier from remaining surfaces of the mattress on a second side of the barrier, use of a blower to create an air pressure differential between opposing sides of the barrier causes migration of the wash liquid through the mattress from the isolated surface of the mattress to the remaining surfaces for drying the mattress.

A cooling material includes opposite top and bottom surfaces and a central portion positioned between the top and bottom surfaces. The top surface includes a first fiber. The bottom surface includes a second fiber. The middle portion includes the first and second fibers and a third fiber. Methods of manufacture are included.

Knitted device, in particular a knitted fabric, comprising a first area, in particular a rectangular area, from which loops project and at least one second area, in particular a contiguous rectangular area, preferably two contiguous areas on either side of the first area, the second contiguous selvedge area(s) not comprising loops and being designed to allow the knitted device to be attached to a cover designed to cover a moulded object, in particular a motor vehicle seat, for example by stitching, while the first area with loops is designed to cooperate with hooks that project from the moulded object, characterised in that means are provided to prevent or combat fraying of the threads of the knitted device forming the one or more second selvedge areas.
