Complete Footwear Breathability and Thermal Insulation Tester

Complete Footwear Breathability and Thermal Insulation Tester is a laboratory device designed to evaluate the air permeability and heat retention performance of finished shoes. It measures how well footwear allows air to pass through (breathability) and how effectively it insulates against heat (thermal insulation), helping manufacturers ensure comfort, safety, and performance under various environmental conditions.

Applications

The Complete Footwear Breathability and Thermal Insulation Tester is primarily used to evaluate the breathability and thermal insulation performance of shoes. By simulating the conditions of the human foot in different environments, the device measures the airflow rate through the shoe and its heat retention under specific conditions, helping manufacturers and designers understand product performance and optimize design.

(1)Evaluating Shoe Breathability:

Breathability is a key factor affecting footwear comfort. By measuring the airflow rate under a specified pressure differential, the tester evaluates the shoe’s breathability, ensuring adequate air circulation and reducing foot dampness and heat accumulation.

(2) Evaluating Shoe Thermal Insulation:

Thermal insulation is critical for keeping feet warm in cold environments. The tester measures thermal resistance and moisture resistance at a set temperature, assessing the shoe’s ability to block cold air and maintain foot warmth.

(3)Quality Control:

During production, the device can test the manufacturing quality of footwear to ensure compliance with design specifications and quality standards. By comparing breathability and insulation across batches or suppliers, potential quality issues can be detected and addressed.

(4)Product Development:

During R&D, the tester evaluates how different materials, structures, and designs affect breathability and thermal insulation. This helps designers optimize footwear for improved comfort and heat retention.

Standards

Testing with the Complete Footwear Breathability and Thermal Insulation Tester should follow relevant industry standards to ensure accuracy and comparability. Common standards include:

(1)GB/T 33393-2023:

Developed by the National Footwear Standardization Technical Committee, effective July 1. 2024. This standard replaces GB/T 33393-2016 and provides guidelines for heat and moisture comfort of footwear, detailing test methods, equipment, and conditions for breathability and thermal insulation.

(2)SATRA Standards:

SATRA (Shoe and Allied Trades Research Association, UK) provides relevant standards for evaluating footwear comfort, including:

SATRA TM 376: Sweat Management Test

SATRA TM 386: Whole Shoe Thermal Insulation Test

SATRA TM 436: Thermal Resistance and Cold Resistance of Whole Shoes

These provide key references for testing footwear breathability and insulation.

Testers should select appropriate standards based on product characteristics and intended use, strictly following prescribed methods and conditions. Regular calibration and maintenance of the tester are essential to ensure accurate and reliable results.
