    摘要： The present invention discloses a weft-knitted spacer fabric and a preparation method thereof, a polyurethane foam composite material comprising the fabric, a preparation method of the composite material and its use in shoe materials. The weft-knitted spacer fabric consists of an upper surface layer (1), intermediate spacer yarns (3), and a lower surface layer (2), and the upper surface and the lower surface layer (1, 2) are connected by the tuck of the spacer yarns in the upper surface and the lower surface layer to form a three-dimensional structure in an integrated manner. The different selected tuck needle changes the connecting distance and the number of connections of the tuck, and the thickness of the spacer fabric and the arrangement density of the spacer yarns are changed by the action of the upper and lower surface layers of elastic yarns. The sole material of the present invention can eliminate the phenomenon of the dislodging of the spacer yarns caused by the repeated compression of the weft-knitted spacer fabric and improve the strength of the PU foam (4), and the thickness of the spacer fabric and the arrangement density of the spacer yarns (3) can be changed according to the variation of the thickness of the sole and the bearing conditions of different parts, such that the overall reinforcement of soles made of PU foam is achieved.

    摘要： The present invention is directed to a liquid, storage stable isocyanate composition (Q) comprising monomeric diphenyl methane diisocyanate (MDI) as component (q1) and an amide with a molecular weight of less than 200 g/mol as component (q2) in an amount of 0.1 to 5 wt.-% based on the sum of the weight of components (q1) and (q2) which adds up to 100 wt.-%, wherein the NCO-content is in the range of from 29.5 to 40.0 wt.-% based on the total weight of the respective isocyanate composition (Q). The present invention is also directed to a process for the manufacture of said liquid, storage stable isocyanate composition (Q) as well as the use of an amide with a molecular weight of less than 200 g/mol for the liquification of at room temperature solid isocyanates. Further, the present invention is directed to the use of an isocyanate composition (Q) of the invention for the synthesis of polyurethane foams, compact polyurethane elastomers or thermoplastic polyurethanes.
