What are the testing items of shoes?

26 \ Oct

Shoes are essential items in our daily lives, and as people's enthusiasm for the pursuit of quality rises, more and more users tend to enjoy high-quality shoes, the proportion of per capita ownership of footwear products is also rising. And for manufacturing enterprises and businesses, more should take this consumer trend, strict control of the production quality of shoes products, good shoes related product testing, to provide users with intuitive shoes quality inspection report, to explain the quality of their own products to ensure, then you know your shoes are to go through what testing projects?

一, Shoe flexing, bending and abrasion resistance testing

The folding resistance of shoes is a physical performance test item. Folding resistance is one of the main indicators of the inherent quality of shoes. By simulating the continuous walking state of human feet and the folding resistance test can directly reflect the strength, toughness and overall quality of the shoe upper and sole, the combination of fastness and durability of the enclosing strip, etc.

The result of the folding resistance test directly affects the determination of the quality of the finished shoes, so the folding resistance test method is particularly important in the physical testing methods, usually into the shoe folding resistance test principle of work is to put the shoes on the folding resistance test machine, to a certain angle, a certain frequency of flexing test, measuring the sole and the circumference of the shoes in a certain number of flexing cracks (mouth) and open glue length, and observe the changes in the upper.

二, footwear hardness testing

Comfortable shoes have a certain function of absorbing and reducing the impact of the ground, if the shoes do not have a good shock absorption system to alleviate this impact, it will make the feet feel exhausted and also cause impact injuries to the human knee, waist, back and brain.

三, footwear peel strength testing

3 different kinds of shoes peel strength test methods

①: the shoe (toe) is peeled from the sole and vamp bonding process, installed on the tension test machine, and the whole shoe is divided into several points according to the customer's requirements, and the peeling force of each point is measured, and then the peeling strength of each marked point is divided by the width of each marked point to obtain the peeling strength of each point.

②: The entire adult shoe sole and the upper surface is cut, the sole side wall and the vamp bonding left 1 ~ 2cm width, the general adult shoes are marked on average around the 22 points, children's shoes are marked on 12 points (can also be increased or reduced according to customer requirements), such as the outsole side wall and the vamp bonding sewn at the outsole line, the outsole line must be removed first, and then the specimen clamped on the tension machine to measure the peel force of each point, remove the The width of the outsole edge wall bonded to the upper, the peel strength is calculated.

③:The sample will be made when the outsole wall and the upper bonding cut the same width of 1cm, measured the peel strength of each point.
