Abstract

The utility model relates to an improved structure of shoes and boots, and the structure mainly comprises a shoe surface and a sole, with the sole positioned at the bottom of the shoe surface to form a whole boot. The shoe surface is mainly made of PU foam so that the shoe surface is good in ventilating, thus the user is comfortable while wearing the shoes.

Description

A kind of structure-improved of footwear boots

Technical field

The utility model is relevant with shoes, particularly relevant for a kind of structure-improved of footwear boots.

Background technology

With present commercially available footwear boots, mostly emphasizing that its wear comfortableness attaches most importance to, yet whether shoes are comfortable on wear, and the most important is whether its gas permeability is good; Only, shoes of being peddled on the market, its gas permeability still is confined to the position of shoe-pad, gas permeability for vamp is then seldom paid attention to, and people's foot is when the wear shoes, major part is all coated by vamp, therefore if whole pair of shoes (containing vamp) all have air permeability and good, can make people more comfortable on wear; And be used for improving the modal mode of vamp gas permeability at present on the market, be the vamp that adopts animal's leather to make, by the natural pore that animal's leather had, has the breathable effect inside and outside making vamp, the manufacturing cost of right this measure is but quite high, therefore improve the price of footwear boots finished product relatively, and make ordinary consumer to bear.

The utility model content

Main purpose of the present utility model is to provide a kind of structure-improved of footwear boots, its not only have air permeability and good and have in addition cheap, the mass producible advantage.

For achieving the above object, the structure-improved of a kind of footwear boots that the utility model provides consist predominantly of a vamp and a sole, and this sole is the bottom of being located at this vamp, and offers a welt in the top of this vamp; This vamp includes:

One foaming layer is the main body of this vamp, and this foaming layer is made of polyurethane (PU) foaming thing, and makes this vamp have air permeability and good and elasticity;

One leather layer is located at the skin of this vamp;

One tissue layer is located at the internal layer of this vamp, touches with wearer's sufficient splice grafting.

Wherein the foaming layer density of this vamp is about 322kg/m ³

Wherein the foaming layer gas permeability of this vamp is about 450l/m ²Sec.

Wherein the foaming layer tensile strength of this vamp is about 5.5kg/cm ²

Description of drawings

In order more to understand characteristics of the present utility model place, lift a preferred embodiment and conjunction with figs. and be described as follows, wherein:

Fig. 1 is the stereogram of the utility model one preferred embodiment.

Fig. 2 is the amplification view at Figure 1A position, in order to show the internal structure of this vamp.

The specific embodiment

See also Fig. 1 and Fig. 2, the utility model provides a kind of structure-improved of footwear boots, consist predominantly of a vamp (11) and a sole (21), wherein on the top of this vamp (11), offer a welt (12), use foot can be set in wherein for the user, and this sole (21) is located at the below, bottom of this vamp (11), to constitute complete footwear boots (10); This vamp (11) includes:

One foaming layer (14) is the main body of this vamp, and this foaming layer is made of polyurethane (PU) foaming thing, has air permeability and good;

One leather layer (16) is located at the skin of this vamp (11), and is made by harder leather, and is coated on the skin of these footwear boots (10), so that these footwear boots (10) are more durable;

One tissue layer (18) is located at the internal layer of this vamp (11), is made of soft fabric, in order to contacting with wearer's foot, and can get preferable sense of touch.

In this special one carry be, if giving drying with a foaming thing of pulverizing, this PU foaming owner mixes again with the foamable reaction thing, and this foamable reaction solution is fully infiltrated in this pulverizing foaming thing by the action of a spreading, mix stirring with another foamable reaction solution again, and import a shaping district with the foaming reaction, and get the required PU foaming thing of the utility model; Step by spreading is fully infiltrated the foaming thing of this pulverizing and this foamable reaction solution, so, with make after the moulding the foaming thing have preferable tensile strength, vapor-permeable type and other physical propertys, and learn through experiment, its density of foaming layer of the present utility model is about 322kg/m,, its gas permeability is about 450l/m ²Sec, and its tensile strength is about 5.5kg/cm ², and have better gas permeability than general foaming thing commonly used.

Via the structure-improved of the made a kind of footwear boots of said method, it has following advantage:

One, good gas permeability: because the intergranular sky of foamed that this foaming material utilization is pulverized The crack is filled with new foamed, and these new foameds can infiltrate the foamed particle that each is pulverized Inside, and carry out foamable reaction, the made foamed of method has high density and ventilative thus The property advantage, therefore by the made vamp of this foamed, have good gas permeability.

Two, effectively reduce cost, and can produce in a large number: be made with higher-priced animal's leather Shoes are compared, and the utility model provides a kind of structure-improved of footwear boots, its cheap can be big Amount is produced, and selling price meets general mass consumption person.

Claims
