<p>Leather is based on a needle-punched non-woven and is particularly for use in sports and leisure shoes. The non-woven contains at least 20 wt.% (40-60 wt.%) on fibre content, of nylon fibres of trilobal cross-section and has a wt. per unit area of 300-2500 g/m2 and a thickness of at most 3 mm. All the fibres have not been shrunk, and they have a linear density of 1.5-6 dtex. - Pref. non-woven also contains nylon and/or viscose and/or cellulose fibres of round cross-section.</p> |
