The invention relates to a fixing device for detecting fabric freezing resistance and an application method thereof. The fixing device is composed of a fabric fixing spring plate, an angle adjusting fixed rod and a double-groove water collecting box. An inner steel frame in the fabric fixing spring plate is used for fixing fabric. When the angle adjusting fixed rod is adjusted to be at 45 degrees, a water spray test can be simulated by spraying water vertically from top to bottom, and the surface moisture resistance of the fabric can be detected in a semi-quantitative mode according to the state of water drops on the fabric; when the angle adjusting fixed rod is adjusted to be at 90 degrees, a hydrostatic pressure test can be simulated by spraying water horizontally from left to right, and the water permeability resistance of the fabric can be detected in a semi-quantitative mode according to the water flux. The fixed rod can be adjusted according to needed angles, different parts of a human body and the worn fabric in different states can be simulated, the water spray test is conduced under a low-temperature environment, and the freezing resistance of the fabric can be detected in a semi-quantitative mode according to the freezing time and the weight of ice blocks. The fixing device is convenient to carry after being folded, easy to use and applicable to detecting fabric freezing resistance.
