In the insole market, PU insoles and microfiber insoles are two common material choices. Although they are all designed to provide foot comfort and support, they have significant differences in materials, manufacturing processes, production processes, and various parameter values of the finished insoles. This article explores these differences in detail and analyzes their respective application areas and advantages.
1. Material differences
PU insole, that is, polyurethane insole, is an insole made of polyurethane material. Polyurethane is a synthetic material with good elasticity and wear resistance. Microfiber insoles are made of microfiber material, which is usually made of polyester fiber or polyamide fiber after special treatment. Microfiber has a delicate feel and good breathability.
2. Production technology and process
The manufacturing process of PU insoles mainly includes steps such as mold making, material filling, vulcanization and molding. Among them, vulcanization molding is a key step. By controlling the vulcanization time and temperature, PU insoles with different hardness and elasticity can be obtained. The production process of microfiber insoles pays more attention to material pre-treatment and surface treatment, such as heat pressing, printing, etc., to provide a comfortable wearing experience and beautiful appearance.
3. Differences in parameter values of finished insoles
Thickness and weight: PU insoles usually have higher thickness and weight, providing better support and stability. The microfiber insole is thinner and more suitable for wearing occasions that require high breathability and lightness.
Hardness and elasticity: The hardness and elasticity of PU insoles can be achieved by adjusting the material formula and vulcanization process, so it has a larger adjustable range. The hardness and elasticity of microfiber insoles mainly depend on the structure and processing methods of the fibers, which are relatively fixed.
Hygroscopicity and breathability: Due to the particularity of its fiber structure, microfiber insoles usually have better moisture absorption and breathability, and are more suitable for use in humid or high-temperature environments. PU insoles are relatively weak in this regard.
4. Application fields and respective advantages
PU insoles: Due to their excellent wear resistance and stability, PU insoles are more suitable for use in high-intensity sports or workplaces that require standing for a long time, such as running, basketball and other sports, as well as in industry, service industries and other fields. In addition, PU insoles can also meet individual needs through design innovation, such as customized hardness, shape, etc.
Microfiber insoles: Microfiber insoles are widely used in casual shoes, sports shoes and daily wear due to their lightness, breathability and comfort. Especially in summer wear that requires a high degree of breathability and perspiration, microfiber insoles show obvious advantages. In addition, microfiber insoles also have excellent antistatic properties and can be used in specific working environments.
In summary, there are significant differences between PU insoles and microfiber insoles in terms of materials, manufacturing techniques, production processes, and various parameters of the finished insoles. These differences determine their different application fields and advantages. Therefore, when choosing insoles, the appropriate material type should be selected based on the specific use needs and use environment.
