Scope of Application

【Operating Instructions】

Fabric down-proof performance refers to the ability of a fabric to prevent down or feathers from leaking through the gaps between yarns, expressed by the number of protruding down filaments under specified conditions. It is suitable for testing the down-proof properties of various fabrics used as linings and outer shells for down products.The test involves making a specimen bag of specific dimensions filled with a certain mass of down and feather filling. The specimen bag is then mounted on the instrument. After undergoing actions such as compression, rubbing, and friction, the down-proof performance of the fabric is evaluated by counting the number of feathers, down, and down filaments that protrude from the inside of the specimen bag.
