In addition, a uniform Distribution of the impregnation agent can be achieved more easily if the selected textile material is easier Shape is present.

The beaktantanthars, which have hitherto been frequently used as a geulosic crosslinking agent, tend to form mainly linear and hardly any three-dimensional polymerisation products.

Example 12 : ■ ·

A. Rope of the fibers treated according to Example 11 was in a yarn transfers this with a water-soluble finishing agent sprayed (but without moistening the yarn au) and in a üJextil processed, the 62 threads ia of the warp and 54 in would have,

A rope this luches was steam-pressed with a fold in one end of then _T 6 minutes' heating at 160 ° The fold remained even after repeated washing obtained. The Monsanto crease resistance angle des luohes (the sum of measurements ^ after warp and weft) was 260 °, while this value was 200 ° for an untreated cloth »

Patterns of the untreated cloth remained latent, because of the resin was networked, so that permanent wrinkles as well could be ironed several months after the impregnation of the fibers.
