Abstract

The invention provides a device for testing the protective performance of a shape memory fabric. The device comprises a base fixed provided with a metal rod, a movable bracket rod, a sensor upper-layer bracket and a sensor shell which are retractably arranged, a heat flow sensor, a fabric clamping plate and a data acquisition system, wherein the sensor upper-layer bracket is arranged on the metalrod in a sliding manner through the movable bracket rod; the heat flow sensor is arranged in the sensor shell; the fabric clamping plate is arranged just below the sensor shell; the heat flow sensor is in data connection with the data acquisition system. According to the device provided by the invention, the movable heat flow sensor ensures that the heat flow sensor and a detected fabric are at acontact state all the time in a shape change process of a fabric composition from a room-temperature state to a high-temperature state; the shape change of the shape memory fabric is not influenced, so that the protective performance of the shape memory fabric is accurately measured.

Description

technical field [0001] The invention relates to the field of fabric testing equipment, in particular to a device for testing the protective performance of shape-memory fabrics and its application. Background technique [0002] The industry's requirements for the performance of fire protection clothing are increasing day by day, and the types of heat protective clothing are more diversified. In the early stage of research and development of new thermal protective clothing, the development and performance testing of fabric systems are crucial. The traditional fireproof fabric system consists of a four-layer structure consisting of a protective outer layer, a waterproof and breathable layer, a thermal insulation layer and a comfortable inner layer. In order to improve the protective performance of fabric systems and better meet the needs of wearing and using, more and more dynamic fabric systems have been developed, such as adding phase change materials or shape memory materia...
