Safety shoes material generally is the use of leather and pu and rubber and new type of synthetic conform to and nano materials, but how to distinguish the stand or fall of safety shoes leather? To distinguish the leather quality is best the most effective method is: a, safety shoes, leather is commonly: natural leather is leather, there is a pore, generally harder to see with the eye, the leather can be pressed in his thumb, to see if it's next to the thumb have fine leather grain to grain. Have fine lines, fine lines disappear after let go of the hand, the leather surface plump resilient for better natural leather, with deep wrinkles is natural skin cortex is poorer. Without the tiny grain, for the most part is not a natural leather, including shaving the paster on the second floor, leather. Second, another significant characteristics of natural leather, leather is flawed. General natural leather uppers, in the inside of the shoes and other inconspicuous place, there are a few minor flaws, such as the dermatoglyph uneven thickness, bright malignant, lice malignant, and so on. Cross section of a natural leather, with different density of three layers: the epidermis layer of very fine flexible, there is the density of the dermis, here is a relatively loose meat surface fiber layer, and no obvious boundary between layer and layer. Three shoes, leather shoes, extend to prevent deformation and improve the feet feel and use of reinforcing materials. For shoe material has delicate touch, breathable, and excellent hygroscopic platoon is wet, not off color, etc. In high-grade leather shoes, adopt natural leather and cotton production. If the shoe is a natural leather, shoe is the alternative artificial leather, can be cheap shoes. Most consumers ignore the selection and identification of shoe materials, this is wrong. Four, the selected safety shoes design and color, first check whether the safety shoes material is real, is required. Want to distinguish real leather or fake leather, cowhide, pigskin, sheepskin, or other leather. Leather surface is smooth, fine particles and high intensity; Pig skin surface pore bigger, more rough, appearance is better than cow leather; Skin surface is fine, soft texture. Real leather hand feels acerbity feeling, artificial leather is smooth. Real leather safety section layer has a fixed layer of epidermis and upper leather fiber, artificial leather, not only cloth or leather fibre composite material, and the smells of chemical raw materials. High quality qualified safety shoes should be fine leather, brightness, with double color should be consistent with the part, no color, no disability. Finger presses face not loose surface, coating layer off no crack; In safety shoes material also should be a natural leather, and it is best to sheep leather. Safety shoes material requirements in the soft soft, uniform thickness, not easy to fall off and rub off.
