Abstract
A cloth for dry-cleaning surfaces in general, with the capacity to develop an electrostatic charge during use conferred by the non-woven fabric material of which it is composed, due to the presence of synthetic material fibers with different denier (yarn count). Compared with known cloths for dry-cleaning surfaces, the one according to the invention has the advantage of acquiring an electrostatic charge autonomously, thus superseding the traditional need to resort to the use of specific auxiliary chemical additives.
Claims22
Non-woven fabric material provided with the capacity to develop an electrostatic charge, characterised in that it is formed of fibres in synthetic material with different deniers or counts.
Material as claimed in one or more of the above claims, characterised in that at least 3% of its surface is formed of fibres with finer deniers/counts.
Material as claimed in one or more of the above claims, characterised in that it has a density of less than 1.3 g/cm3, preferably around 0.6 g/cm3.
Material as claimed in one or more of the above claims, characterised in that it has the capacity to acquire an electrostatic charge of at least 1 Volt.
Material as claimed in one or more of the above claims, characterised in that the aforesaid fibres are polyacrylic, polyamide, polyester or polypropylene fibres.
Material as claimed in one or more of the above claims, characterised in that it is formed of 90% of 1.5 denier polyester fibres and 10% of 0.14 denier polyester fibres.
Material as claimed in one or more of the claims above, characterised in that it has a mesh of reinforcing material.
Cloth for dry-cleaning surfaces in general with the capacity to develop an electrostatic charge during use, characterised in that it is produced with the non-woven fabric material as claimed in one or more of the claims above.
