I've been in Bavaria for 35 years and my better half is Bavarian thru and thru. Krachlederne is a short Lederhose, usually greasy or fatty looking (speckig) through age or being handed down thru the generations, and with a flap at the front to let down and do the obvious, which if less accurately aimed can add to the texture.

Hohenadel Textile W'buch gives:
krachend - scroopy, krachender Griff - scroopy, silky, crunchy handle/feel
krachen - scroop
Krachausruestung - crunch finish, scroop finish.

Link for 'scroop'...describes finish.

Silk is very often "brightened" and "scrooped" after dyeing; this is usually accomplished by passing the dyed goods through a bath containing acetic or tartaric acid, squeezing, drying, or steaming and stretching in a special machine.

The effect of the acid is to give the fiber a crackling or crunching sound when squeezed in the hand, which is the so-called " scroop "; while the steaming and stretching serves to straighten out the fiber and give it a high luster. In old methods of dyeing woolen goods the dyed color was frequently it saddened " by passing the goods through a bath containing copperas (sulphate of iron). The effect of this was to form an iron lake with the dyestuff (usually a vegetable mordant coloring matter), which was always darker and duller than the other lakes, and thus dulled or " saddened the color.
