The present invention provides a non-aqueous process for the dyeing of a dyeable material at an elevated temperature by contacting a dyeable material with a dye composition at an elevated temperature in a non-reactive environment. The dye composition temperature and the time of contact between the dye composition and the dyeable material are sufficient to effectuate the dyeing of the material. The dye composition comprises a substantially non-aqueous solvent and a dyestuff.

An apparatus for permanently setting pre-formed creases of a pair of pants comprises a stanchion member and a pair of spaced-apart substantially parallel support members extending substantially horizontally from the stanchion member. A substantially horizontal upper crease blade is fixed to each support member and has a lower crease blade pivoted thereto. The free ends of the crease blades extend away from the stanchion member and include applicator nozzles that are directed upward for the upper crease blades and downward for the lower crease blades. When a pair of pre-creased pants are slipped over the crease blades and the lower crease blades are pivoted downward, the pants are pulled taut at the hems between the pre-formed creases. As the pants are pulled off of the crease blades a pumping mechanism supplies a flowable, curable setting material such as silicone rubber to the applicator nozzles, which apply a coating of setting material to the inside surfaces of the pant legs along the creases. When the setting material cures, it hardens into the shape of the creases. A method, using the apparatus, for permanently setting all four creases of a pair of right-side-out pants simultaneously also is disclosed.

A fabric sample is stretched between two grippers mounted on two moveable parts, one of which slides on the other. A pair of plier-like hand grips exerts a force through a coil spring on the two moveable parts so that the displacement of the two parts relative to each other measures the amount of stretch of the fabric sample whereas the amount of compression of the spring indicates the force being applied to achieve that amount of stretching.
