About This Product
Drape describes how a fabric hangs and folds under its own weight, which matters for garments and furnishings. In a drape meter, a circular specimen is held on a support so that its edge hangs freely, and a lamp casts its shadow onto light-sensitive paper. The paper is developed in ammonia vapour, and the area of the shadow shows how far the fabric has spread out or folded. Students use it to compare the drape of different fabrics.
Frequently Asked Questions
Q1. How does the Drape Meter record the shadow of the specimen?
A lamp at the top of the exposing chamber lights the specimen. Rays that are not intercepted fall on light-sensitive ammonia paper and expose it, giving a boundary between exposed and unexposed areas.
Q2. How is the exposed paper developed?
It is kept in the ammonia vapour developing chamber below the exposing chamber, which has an arrangement to hold ammonium hydroxide.
Q3. What accessories are supplied?
A metal template of 250 mm diameter with a central hole, a specimen pressing disc, one hundred sheets of ammonia process paper and one bottle of ammonium hydroxide.
