Frayed ends are history

Spacer fabrics are created successfully with ultrasonic cutting fusion technology

The first object manufactured with ultrasonic cutting fusion technology: a high-volume microfibre cleansing wipe

A remarkable machine is able to cut high-volume microfibre fabrics and synthetic fibre spacer fabrics in a single work step and “softly” seal their cut edges at the same time. The technology has been developed and patented by TINAtex GmbH, jointly with a machine building company, and it can be used to manufacture new products without the aid of sewing machines. The first product created with this new technology is a micro-fibre cleansing wipe which works without chemical cleaning additives.

Produced in a single work step: Cleaning cloths with no inconvenient seams

“The major advantage with this technology is that the cloths no longer have any inconvenient seams”, says company boss Jürgen Schuster. The fibre material is plasticised without heating above its melting point, and this produces a soft edge with no perceptible border, making the FILUMEXclean cloths ideal for cleaning delicate surfaces (car varnish, museum exhibits, dusty furniture tops or mirrors with fingerprint smudges).

Also called Cut’n’Seal, the process is described in more detail on the internet (www.ultraschall-trennschweißen.eu), and at the moment it is being used to create 3D textiles with a thickness of up to 10 mm. With a view to further applications (seat cushions made from spacer fabric, for example), the Oelsnitz/Vogtland based company plans to melt the pile threads at the edge so that they bond evenly and can no longer perforate the carrier material. Then it should be possible to separate rounded shapes by ultrasonic cutting fusion as well so the edges do not fray. For improved tactile properties, these cushions are surrounded with a border and provided with rubber loops.

New cutting and bonding technology is already able to process spacer fabrics with pile yarn of up to 10 mm

This innovative technology for visually perfect and reproducible weld seams is suitable for many synthetic materials. It can also be used to manufacture sandwich products with a certain degree of media impermeability. It is particularly advantageous for applications in which conventional sewing equipment is not ideal.
