A thermally fusible textile fabric usable as a fusible interlining material in the textile industry includes: a backing layer having a textile material on top of which has been applied an adhesive compound structure including a polyurethane coating containing a polyurethane mixture including at least one polyester urethane, at least one polyether urethane, and at least one polycarbonate urethane. The polyurethane mixture has been at least partially crosslinked with a crosslinker including at least one isocyanate blocked with a blocking agent at at least one isocyanate group.

A multilayer protective tape for rotor blades of wind energy turbines is provided herein. The protective tape comprising a protective top layer comprising a polymer film, and an adhesive bottom layer. The top layer having a continuous surface (S) that is outwardly curved or outwardly trapezoidal such that the tape has a cross-sectional profile having an inner section between first and second edge lateral sections. The inner section comprises up to 30% of the width of the tape and has a thickness (Ti), while the first and second edge lateral sections have a thickness of T1 and T2, respectively, wherein Ti greater than each of T1 or T2, and the thickness (T1 or T2) of at least one edged lateral section is at most 600 &#x3bc;m and the thickness of the inner section (Ti) is at least 330 &#x3bc;m. Also provided is a method for applying the tape to rotor blades and a rotor blade protected by said protective tape.

A thermofusible sheet material which can be used as a fusible interlining in the textile industry, has a carrier layer made from a textile material to which a polyurethane foam coating is applied. The polyurethane foam has a pore structure in which more than 50% of the pores have a diameter, measured according to DIN ASTM E 1294, which is in the range of 5 to 30 &#x3bc;m.

Thermofusible sheet material

A thermally fusible sheetlike structure, especially usable as fusible interlining in the textile industry, has a carrier ply made from a textile material to which has been applied a two-ply adhesive composition structure comprising an underlayer directly adjoining the sheetlike structure and an overlayer disposed upon the underlayer, wherein the underlayer contains a first hotmelt adhesive and the overlayer a second hotmelt adhesive, wherein the first hotmelt adhesive has a melting point of &#x3e;140&#xb0; C. and a melt flow index (MFI) value of &#x3e;50 g/10 minutes (190&#xb0; C./2.16 kg) and the second hotmelt adhesive a melting point of &#x3c;145&#xb0; C. and an MFI value of &#x3c;50 (190&#xb0; C./2.16 kg).

Thermally fusible sheetlike structure and method for production thereof

The invention relates to a continuous self-metered process of forming a multilayer film comprising at least two superimposed polymer layers comprising the steps of: (i) providing a substrate (); (ii) providing two or more coating knives () which are offset, independently from each other, from said substrate () and/or from an adjacent coating knife to form at least one substrate gap () relative to the surface of the substrate () and at least one outlet gap () relative to the surface of an adjacent coating knife; (iii) moving the substrate () relative to the coating knives () in a downstream direction (), (iv) providing curable liquid precursors of the polymers (I, II, III) to the upstream side of the coating knives () thereby coating the two or more precursors (I, II, III) through the respective gaps () as superimposed layers () onto the substrate (); (v) optionally providing one or more solid films () and applying these essentially simultaneously with the formation of the adjacent lower polymer layer, and (vi) curing the precursor of the multilayer film thus obtained; wherein a lower layer of a curable liquid precursor (I, II, III) is covered by an adjacent upper layer of a curable liquid precursor (I, II, III) or a film (), respectively, essentially without exposing said lower layer of a curable liquid precursor (I, II, III).
