Over the years, certain types of shoes, waterproof shoes (such as hiking shoes and golf shoes), and certain occupations (such as firefighters and farm workers) is a basic requirement. But now consumers expect the daily also has certain procedures footwear waterproof, and this demand is growing trend. Because modern footwear with limited scope and structure of materials, which may have an extremely complex issue, but in mostCircumstances, can provide effective and durable options.

Water and testing

Waterproof (Waterproofness) the term, in the footwear industry tend not to use, because it implies that the water be placed in the shoes completely outside. To achieve this purpose, the Trade Descriptions will be very likely to cause conflict and consumer protection laws. In fact, most English-speaking countries the term is used in a more secure water (waterresistance).

SATRA recommended, to ensure the shoes performance, with or without time limit, must take an integrated test plan as a shoe backing. Clearly suggested a time limit, because the old materials and structuresOf time, water features will inevitably disappear. In addition to testing outside of footwear production, for every 1 million pairs of shoes, at least one pair of shoes should be independently tested, and more at the scene assessment, to ensure consistent performance.

Combination of materials and shoes all shoes weatherproofing test is to measure the most effective way. Way through the Maeser dynamic conditions, the test can best assess the performance upper materials resistant to water seepage. Relatively speaking this is very strict, but you can wear the most accurate copy of the bending strain encountered. Bally leather uppers are also used through the meter, but the softer bending movement. AllShoe test for assessing the overall structure of the finished product and the water resistance of the gap is extremely important.

Common method of water treatment

Water is integrated in the primary footwear to add one of the characteristics, the traditional shoe-making materials, leather, grease and fatty substances through the coating to the upper, sole and crannies, you can achieve this effect. This method is still used today mainly by the various formulations, but unfortunately, although water resistance early in the wear and effective, but short life, because mopping the floor, bending, etc. will soon wear and damage to the waterproof layer. To restore the water resistance, it must repeat the treatment.

To preventAnother purpose of water is the use of traditional methods, such as rubber, polyurethane or like material with PVC injection mold shoes or boots to help. Good performance of this structure, but the cost to sacrifice comfort, moisture can not be discharged because of the foot. Design possibilities are subject to certain restrictions, although the newer mold injection technology and materials is broadening its possibilities. For example, multi-color and multi-density injection molding, especially for industrial and safety shoes, steel header can be integrated, will increase to boots lining to help maintain its shape. Wellington boots proved molded footwear even help in the "guaranteed waterproof" has played an important role, which has not aProblem.

When the water is extremely important, functional, very good shoes. Moisture absorbing lining (including leather) and a suitable hose has an important role for the comfort. For example, using hot air circulation inside the boots in the work shifts extending between the foot of effective drying is another way of comfort.

Shoes, water resistant to two main requirements must be met: the use of special handling of materials and design of the water with the correct structure. Most types of shoes can use this method, including light weight, no special structure of the leisure style. However, to achieve water resistance, must take an integratedMeasures to effectively remove the foot moisture. Traditional waterproof footwear to an early attempt to integrate in the structures can not penetrate the PVC boots. When the PVC when the barrier remains intact, so that good performance, but can not effectively distribute foot moisture, waterproof layer of the advantages they have been denied.
