Abstract (en)
[origin: WO0238027A2] A hydraulically entangled nonwoven fabric that includes recycled synthetic fibers and fiber-like materials having at least one thread element composed of synthetic material with at least one irregular distortion generated by hydraulic fracture of the thread element to separate it from a bonded fibrous material while the bonded fibrous material is suspended in a liquid. This material may be used as a wiper or an absorbent material. A method of forming the material includes the steps of: (a) providing a layer of recycled synthetic fibers and fiber-like materials having at least one thread element composed of synthetic material containing at least one irregular distortion generated by hydraulic fracture of the thread element to separate it from a bonded fibrous material while the bonded fibrous material is suspended in a liquid; (b) hydraulically entangling the layer to form a nonwoven web; and (c) drying the web.
