Definitions
- the invention relates to a method for roughening textile fabrics, such as jeans fabrics, articles of clothing or the like made therefrom, the fabrics being washed in a washing machine with water with the addition of a granular abrasive.
- the items of clothing to be treated are washed with water, to which a certain proportion of pumice gravel with a grain size of about 20 to 50 mm is added as an abrasive (see, for example, US Pat. No. 4,750,227).
- the washing process is carried out, for example, in perforated sheet washing drums.
- the pumice pieces scrub and roughen the fabric surface.
- the fabric loses its stiffness and its uniform blue, smooth surface.
- the tissue becomes softer and fluffier.
- the abrasion effect of the pumice pieces in addition to the washout effect of the water, removes the indigo dye more or less from the fabric surface. This effect naturally occurs increasingly at the seams and hems of the garments.
- the pumice pieces are subject to constant wear and tear during the washing process, above all due to the mutual friction, so that their grain size steadily decreases. At the end of the washing process, the pumice pieces are so small that they are discharged with the washing water through the perforated plates of the washing drum.
- the used pumice with grain sizes of e.g. less than 10 mm is separated from the wash water.
- the known method now has the disadvantage that the pumice that is used up in considerable quantities cannot be recycled with economically justifiable effort.
- the object of the invention is to propose a method in which a recyclable material is used instead of pumice.
- foam glass bodies are used as the scouring agent.
- Foam glass fragments with an essentially angular or cubic shape have proven themselves (claim 7).
- the foam glass body reduced to a grain size smaller than the hole diameter of the perforated plate washing drum during the washing process in a perforated plate washing drum can be separated and reused for the production of foam glass (claim 2).
- a recycling circuit can be easily fed and processed, for example, together with recycling bottle glass to the foam glass bodies of the required grain size.
- foam glass is usually mostly closed-pore.
- additives from the wash water are primarily deposited only on the surface of the granules.
- the separated foam glass bodies are contaminated to a much lesser extent than the separated pumice pieces. Accordingly, recycling is considerably simplified, it should be noted that the additives adhering to the foam glass bodies are generally burned out in the subsequent manufacturing process for the foam glass and are thus rendered harmless. There is therefore no special cleaning step for removing the pollutants from the foam glass bodies.
- foam glass as an abrasive is that the garments feel softer and fluffier than pumice-washed ones.
- the use of foam glass shortens the washing cycles by 10 to 30% depending on the type of fabric. As a result, the energy costs of the washing systems are reduced and their degree of utilization increased.
- An advantageous grain size for the foam glass body is about 20 to 50 mm (claim 3).
- the method according to the invention can also advantageously be integrated into the glass recycling cycle.
- additives for bleaching, impregnating and / or softening the fabric can be added to the wash water during the washing process.
