* * * This invention regards a new fabric destined for use in the manufacture of disposable products for personal hygiene and domestic use such as, for instance, serviettes, cloths and towels for domestic cleaning.
Currently, disposable products are made from cellulose pulp, plastic, paper and cellulose fibre, using special adhesive, bonding agents, to hold the fibres together.
However, all these products lose consistency when they become wet and cannot be reused. Furthermore, the use of adhesives constitutes a factor of pollution meaning that they are not biodegradable.
The purpose of this invention is to create and present a non-fabric fabric for the production of serviettes, cloths and similar, with a very high absorption capacity, resistant to tears when wet or dry, free from chemical additives and therefore ecological and biodegradable.
The purpose and the advantages obtained are achieved with a fabric made according to the following production process.
The fabric is obtained using pure cotton fibres measuring an average of between 8 and 18 mm long.
The fibres are degreased and subject to a hydrophilic treatment in which they are treated with hydrogen peroxide and soap.
The hydrophilic fibres then undergo a mechanical procedure destined to open them up, consisting in combing with carding cylinders.
The treated fibres are deposited evenly in veil form, using a standard air procedure, on a belt, forming a mattress of fabric with a weight per square metre which depends on its final use.
This mattress is then subject to a water-jet treatment during which it passes under a jet made up of very high- pressure water needles which help it gain consistency and stiffness.
The mattress is then oven dried.
Lastly, the fabric mattress is transferred onto a reel and cut to suit the final use.
The result is a non-fabric fabric which can be used to make exceptionally versatile products, such as handkerchiefs, serviettes, cloths and towels, including cloths for cleaning windows and floors, and for drying wet surfaces without leaving behind fluff or smears.
Furthermore, it can be partially reused, as it is resistant to several washes.
