Outer sole materials of leather shoes include: lemon gum, polyurethane, modified polyvinyl chloride, etc., and they have been specified in the end-of-end bending resistance, wear resistance, and hardness of leather shoes in the national industry standard Huaihe. The folding and abrasion resistance testing machines are used. And hardness test to test. When selecting shoes, press the sole with your fingers should be flexible, there is no small piece falling off at the bottom of the hand, and it is not sticky when touched, and soft when bent. At present, the quality of outsoles in the rubber rubber shoes is more problematic, and the phenomena of fracture and lump shedding occur from time to time. This is due to the fact that the profit of the shoe sole production plant disregards the quality of the product and the amount of rubber contained in the rubber sole is low, so reclaimed rubber and other fillers are used. Excessive, so that the quality of soles.
2. What is the function of leather shoes and steel shoes? How to distinguish the advantages and disadvantages?
Each male and female leather shoe has a steel hook (except for flat shoes and wedge shoes). It is installed between the outer sole and midsole of the sole of the foot (loin window). It is the backbone of the shoe and keeps the curvature of the bottom and Stabilizing the heel function, the middle and high heels are particularly important. Leather shoe steel heart standard Huai provides longitudinal bending stiffness and hardness and other performance indicators. When picking a shoe, you can use your hand to press hard on the inner sole of the shoe. If the shoe is worn, you may find that the heel is skewed (not nails are not firm) and the heart is empty or uncomfortable. Check whether the heart is broken. If the break in the three-period period, can be returned.
3, why do shoes open plastic?
Adhesive shoes upper and bottom adhesives are not easy to open, but plastics are more common. There are many reasons for opening the rubber. The main reason is the selection of factory raw materials and inappropriate process control. The rubber sole and the leather can be adhered by using neoprene, and the imitation leather base and the polyurethane base containing more resin components are difficult to be effective, and the polyurethane finger glue or other adhesive must be used instead of sticking, because an adhesive does not Suitable for any material. Before bonding, it is necessary to polish the soles and uppers, brush and bake them several times, and press them together with a press to stick. The adhesion of leather shoes is controlled by peeling strength indicators. The index is measured with a peel tester. When selecting the shoes, check whether the bottom and the bottom of the adhesive are firm, whether the plastic is open or not, and be careful when using it.
4, using cardboard to make insoles, quality and reliable?
In the past, insoles were made from pigs and cows. Natural leather resources are now reduced. Alternative materials are used to replace certain natural materials. For example, footwear insole board is widely used at home and abroad. The moisture absorption, air permeability, resistance to flexion, interlayer peeling strength, tear resistance, and dimensional stability of insole board for good quality footwear can fully meet the requirements of use, such as breakage, shrinkage, deformation of the inner bottom board after wearing. From the hard, stratified, etc. are of unqualified quality.
5. What are the quality requirements for the main heel and Baotou?
The main heel position is at the back and bottom of the leather shoes. It is wrapped in the front head of the leather shoes. They are all designed to make the shoes not deformed. They should be installed between the upper layer and the upper layer of the shoe. Use the thumb to press the head of the bag is not soft not deformed, with the thumb and index finger press the main part of the lower part of the 2 / 3 Department is not soft not deformed, but also the size, height should be - so that it passed.
6, how to check the shoes?
You can reach into the shoes by hand and explore whether there are defects in the wear of the shoes. For example, whether the insole is standing on the shoe (the length of the insole is not short), whether the shoes are flat and the inside of the shoe is away from the nail tip. And nail tail is not equal.
7. Why do some shoes have discoloration or change of color after they polish their shoes?
There are two reasons for this phenomenon. One is the quality of the shoe polish. If the shoe polish can destroy the upper leather coating, it can cause discoloration and change of the upper. Second, there is a kind of leather called "oil skin" is a cow leather. One is a high-end product with a very thin coating, strong adsorption and permeability, and good hygienic performance. If there is a problem with the quality of the shoe polish, or when it is soaked in oil, it is directly squeezed onto the upper and the spot of oil will form spots. Dripping with ink or hair dye, petrol will cause pollution. Therefore, care should be taken when wearing it.
8, how to identify the quality of leather shoes?
To determine the quality of a pair of leather shoes, you need to look at both the appearance and the internal indicators. Since the internal indicators often need to use detection equipment, it is more practical for a consumer to identify the quality of leather shoes from the appearance. From the aspect of appearance, the quality of the leather shoes is mainly determined by the quality of the material of the leather shoes (including the upper, the sole, and the shoe) and the performance of the work.
