Leather shoes composition and design method
In daily life, many people can see wearing leather shoes, not only beautiful, but also can bring out a person's temperament. So everyone knows how the construction of leather shoes is? What are the methods of leather shoes design? Today, the editor will talk about the composition and design method of leather shoes, and I hope to help everyone. The details are as follows.
Leather shoes composition
Sole
The soles of common leather shoes are composed of outsole, insole, semi-inner, hook, pad and heart filling, which can isolate the foot and the ground and cushion the effect of the ground on the foot. The outsole is in direct contact with the ground and is subjected to various functions such as bending, squeezing, friction and the external environment; the inner bottom directly bears the weight of the human body, and transmits the gravity to the outsole and the heel, and the inner bottom is bent and squeezed. In addition to the effect of friction, it is also affected by the sweat of the foot, the humidity inside the shoe, the temperature, etc.; the hook is fixed between the inner bottom and the outer sole of the waist and the sole of the leather shoe to strengthen the back of the leather shoe and support the arch of the foot to make the waist of the leather shoe The nest has a certain elasticity to maintain the position and shape of the sole and the heel; the pad and the filling are used to fill the joint between the upper and the insole to improve the cushioning and heat insulation of the sole.
Upper
The upper of the leather shoe is stitched from the front, back and tongue. The front gang corresponds to the front end of the foot and the active part of the metatarsophalangeal joint, and is subjected to flexing, stretching, squeezing and rubbing under the action of the foot. The heel of the rear gang is machined into a fixed shape similar to the heel. When walking and wearing the shoes, the back gang is also flexed and stretched. The front and back gangs are usually sutured at the lumbar fossa on both sides of the arch. The upper of the part plays the role of wrapping the foot and holding the inside of the arch. The general leather uppers are lined to reinforce the upper and protect against wear and absorb some of the sweat.
Heel
Protect the heel of the outsole from the upper to avoid wear and tear.
The contact area between the sole and the ground is reduced to reduce the thermal conductivity of the shoe, preventing water on the ground from entering the shoe from the heel and the lumbar region, and also having the effect of absorbing shock energy generated when the heel touches the ground. The height of the heel is appropriate, so that the weight of the human body can be distributed reasonably in various parts of the foot to improve the elasticity of the arch.
Main with
Between the upper and the lining of the heel of the instep, the lower portion is firmly integrated with the upper, the insole, the outsole, and the heel, so that the heel portion maintains a fixed shape. The main heel keeps the foot in the correct position in the shoe. The main heel is thinner and more elastic, and can gently grip the upper part of the heel. When wearing, the shoes do not fall off with the foot.
Inner head
The inner end of the leather shoe is designed to maintain the shape of the toe and prevent deformation. Some labor protection shoes are equipped with steel plate forming toe caps to ensure that the toes are not bruised.
Leather shoe design method
Leather shoes can be designed in a variety of ways, but they need to meet the requirements. Regardless of the design method, technical points must be considered. The methods of designing leather shoes are summarized as follows:
Drawing paste method, paste design method (sticking method), graphic design method, comparison design method.
1. Painted paper method: first draw a sample on the enamel and then take a sample.
2. Paste design method: use paper directly on the shoe last to draw the upper.
3. Graphic design method: firstly unfold the kneading surface, then perform the flexing treatment, and design the help sample according to the basic control line.
4. Comparison design method: use paper to directly sample on the raft.
The above is about the introduction of the composition and design method of leather shoes. I hope that everyone can understand the composition and design method of leather shoes.
