Abstract
A spun-bonded fabric consolidated by a hot-melt binder, composed of polyester filaments and of polyester binder filaments serving as the hot-melt binder is described. The weight per unit area of the spun-bonded fabric is in the range between 20 and 120 g/m.sup.2, the individual titer of the load-bearing filaments and of the binder filaments is in the range between 1 and 7 dtex, and the proportion of the binder filaments is less than 10 percent by weight. This is a lightweight spun-bonded fabric which is distinguished by a particularly high dynamic capability, i.e. a particularly high resistance to alternating stresses. The lightweight spun-bonded fabric can be used, for example, as a reinforcement for shoes and garments, as a carrier material for curtains and blinds, as seat covering, filter material, and the like.
