Depth Analysis Of Material Characteristics Of Leather Shoes

< p > < strong > 1, skin < a href= "http://www.91se91.com/" target= "_blank" > shoes < /a > the quality of outboard how to distinguish < /strong > /p >

< p > the outer sole of leather shoes is made of lemon glue, polyurethane and modified polyvinyl chloride. The flexural properties, wear resistance and hardness of the outer leather shoes are specified in the national standard. The flexure, wear resistance tester and hardness tester are used for testing. When choosing shoes, fingers should press the soles to be elastic, and the bottom of the hands should not be clutched with hands.

At present, there are many problems in the outsole quality of lemon rubber shoes. The phenomenon of breakage and massive shedding often occurs. This is because the profit of sole production plant is not in the quality of products, and the rubber content in the rubber base is low, so that the quality of the sole will be reduced by using reclaimed rubber and other fillers. < /p >

< p > < strong > 2, what is the function of leather shoe hooks and how to distinguish the advantages and disadvantages < /strong > /p >

< p > each male and female a href= "http://sjfzxm.com/news/index_x.asp" > leather shoes < /a > all have a steel hook (except for flat shoes and slope shoes). It is installed between the bottom and bottom of the foot center (waist window). It is the backbone of shoes, which keeps the bottom arc and the role of stabilizing the heel. Middle and high heeled shoes are especially important.

When you pick your shoes, you can use your hands to press the center of the shoe firmly. If you wear the shoes, you can see that the heel is not empty or uncomfortable. You can check whether the heart is broken.

If broken in the three package period, it can be replaced. < /p >

< p > < strong > 3, why do leather shoes open glue < /strong > < /p >

< p > adhesive leather shoes and bottom are not firmly bonded, and gluing is more common. There are many reasons for opening glue, mainly because of raw material selection and improper process control.

Rubber bottom and a href= "http://www.91se91.com/" target= "_blank" > leather < /a > can be adhered to by using neoprene, but the imitation leather and polyurethane base with more resin composition will not work well. It must be replaced with polyamine finger glue or other adhesive to adhere to it, because one kind of adhesive is not suitable for any material. Before the bonding, the sole and upper shoe should be rubbed and brushed, then glued and baked and pressed together with the press.

When choosing shoes, pay attention to check whether the adhesive is firm, whether it is open or not, and pay attention to rain and ice when wearing it. Because leather shoes are easy to open after being exposed to water. < /p >

< p > < strong > 4, using cardboard as an insole, is the quality reliable? < /strong > /p >

< p > in the past, leather bottoms were made from pigs and cattle inner leather.

Now natural leather resources are reduced. Substitute materials are used to replace some natural materials.

For example, cardboard for shoes is widely used at home and abroad.

Good quality shoes can be completely satisfied with the requirements for moisture absorption, air permeability, flexing resistance, delamination strength, tear resistance and dimensional stability. The breaking of internal cardboard, shrinkage deformation, rigidity and delamination are all unqualified. < /p >

< p > < strong > 5, what is the quality requirement of main and Baotou? < /strong > < /p >

< p > the main position is in the position of the back and bottom joints of the leather shoes. They are wrapped around the front and the front ends of the leather shoes. They are designed to make leather shoes without deformation, and should be installed on upper and shoes.
