What properties need to be tested in the quality inspection of leather shoes?

The quality of leather shoes covers comfort, aesthetics, durability, functionality (including safety) and sanitation. It involves the selection of shoemaking materials, shoe sample design, process manufacturing and many other aspects. It is necessary to use leather testing instruments to strictly check.

      Comfort refers to the touch of leather shoes during wearing. It is mainly related to the shoe cavity, shoe material selection and process processing. Sensory testing is often used, and it can also be identified by trying on. In addition, the hygienic performance of glued leather shoes also directly affects the comfort of the shoes. For example, the comprehensive ability of the shoes to breath, absorb moisture and sweat will bring completely different results to the hygiene and comfort of the shoes.

     Workmanship is the aesthetic characteristics of craft manufacturing. It includes the consistency and coordination of the texture, color, texture and other elements of the shoe material; it also includes the neatness, roundness, and smoothness of the edge of the process, as well as the symmetry and fineness of the stitching line, as well as the symmetry of the outline of each part. Require. Test by senses only.

     Durability—leather shoes are the necessities of human life, and they are also clothing items that are easy to wear and tear. Their durability is especially important, mainly in wear resistance, flex resistance (that is, folding resistance), strength (that is, fastness). Need to Shoes are physically 'smart tested.

     Functionality—In addition to basic functions such as wearing, protection, and convenient sports, the functions of shoes also need to have general wearing performance requirements such as non-slip, breathable, sweat-absorbing and moisture-wicking, heat insulation and warmth retention, and weather resistance; and Anti-smash, anti-puncture, anti-acid and alkali, waterproof, anti-fouling, anti-oil immersion, anti-static and other special performance (i.e. safety performance) requirements, these performances need to pass various special tests, but there is no complete and feasible testing standard at present , generally rely on the special detection and try-on of shoe material performance, or make a general perceptual identification of leather shoes through the senses.

Programmable constant temperature and humidity testing machine

      Recommend a programmable constant temperature and humidity testing machine for everyone. The programmable constant temperature and humidity testing machine can be used for high temperature, low temperature, constant temperature and humidity and other different test conditions. The full-function fault indication includes over-temperature, low water level, test End, compressor overload, etc., can be used for hydrolysis resistance test of leather and shoe materials and frosting test of rubber materials.
