Introduction
Before testing the down-proof property of fabrics, turn the specimen into a bay-type with a certain quality of feather and down inside. Put the specimen into the rotating box while the rotating box is also loaded into hard rubber balls. The rotating box tumbles at a certain speed, bring the rubber balls to a certain height to drop and impact the specimen, which simulates all kinds of squeezing, rubbing and colliding effects of feather and down products in the service process. The down-proof property of fabric is then evaluated by counting the number of down and feather penetrating outside from the specimen inside.
Application
the down-proof property of fabrics refers to the fabrics performance to prevent down and feather from leaking out from the yarn gap. The instrument is suitable for the down-proof property test of various fabrics of lining materials and shell fabrics used for feather and down filled products. The tester consists of a rotating box with forward and reverse rotation and motor control assemblies. The rotating box is made from organic glass material, a cube with smooth internal wall. The instrument has functions, such as intelligent presetting of number of revolutions, automatic stop upon full revolutions, etc.
