Foaming Equipment for Nonwovens.

The use of foam technology in the manufacture of nonwoven fabrics significantly expands the range of end prodcuts and their applications. These end products include composites, coated fabric with a different coating on each side, and saturated products. A major operational advantage of foam technology is its low enrgy consumption and high..

Nonwoven Web Forming - Fiber Overview.

In the first stage of processing, the nonwoven fabric industry uses fibers either as raw mateials or produces fibers in situ from thermoplastic resins. The use of fibers as a raw material exceeds the production of fibers in situ. Critical fiber properties are length, size, shape, surface, luster, crimp, finish, and orientation. Natural fi..

Nonwovens from recycled waste

The production of nonwovens from recycled waste and the development of new nonwovens for optimal recyclability are discussed. Issues of waste avoidance and posiblities for greater recycling are addressed. Uses and ranges of application for specific recycled textile fibres and related technologies are also outlined.

Point bonded nonwoven fabrics

Conjugate fibres comprising a polyolefin and a polyamide are deposited onto a forming surface to form a nonwoven web, and the web is passed into a nip formed by two rollers which are heated to a temperature of about 10℃ below the melting point of the polyolefin. IPC B32B.

Tubular nonwoven fabric comprising circumferentially oriented parallel reinforcing fibres within a tubular nonwoven fabric

A tubular nonwoven fabric has parallel reinforcing yarns extending in a circumferential direction. For USP 5 296 061 see abstract 94W/03734. IPC B29D B32B.

Electret tubular nonwoven fabric comprising circumferentially oriented parallel reinforcing fibres within a tubular nonwoven fabric

An electret tubular nonwoven fabric comprises a tube of nonwoven fabric with parallel reinforcing yarns extending in the circumferential direction. The surface charge density of the fabric is not less than 1×10000000000 coulombs/㎠. For USP 5 296 061 see abstract 94W/03734. IPC G11C B29D B32B.

Apertured, abrasive, absorbent, composite nonwoven web

A composite nonwoven web comprises: a coarse, shot-laden, meltblown, thermoplastic layer which is the surface layer; a supporting, thermoplastic, carrier layer; an a asorbent, meltblown, thermoplastic layer; and a second supporting, thermoplastic, carrier layer. The surface layer and the first supporting carrier layer are formed into a th..

Nonwoven fabric made with multicomponent polymeric strands including a blend of polyolefin and elastomeric thermoplastic material

A nonwoven fabric comprises a first web of extruded multicomponent polymeric strands including first and second polymeric components. The two components are arranged in distinct zones across the cross-section of the strand and extend continuously along the length of the strand. The second component constitutes at least a portion of the pe..

Thermofusion, thermobonding, and heat setting for nonwovens - theoretical fundamentals, practical experience, market development

This concluding part deals with thermally-consolidated nonwoven products and examples of nonwoven fabric machines. Examples of uses include coverstock for hygiene products; fibre mats as replacements for foam fabrics; filter fabrics and upholstery; wadding for thermal linings; thermobonded needled carpets; and thermally-consolidated wet w..

Making multi-axial nonwovens

In Japan, the Polymer Processing Research Institute Ltd has invented a system for producing multiaxial nonwoven fabrics which are claimed to be mechanically stronger and have greater dimensional stability than previous fabrics, and which are believed to have considerable potential in fibrereinforced plastics. The equipment proposed to pro..
