The cotton layer of said shock-absorbing comprises that EVA is cotton.

Said flexible glue main shell layer comprises 1-6 flexible glue piece, and the shape of this flexible glue piece comprises triangle or quadrangle or the pentagon that has the arc limit.

The cotton layer of said shock-absorbing comprises the cotton sheet of 1-6 EVA, and the shape of the cotton sheet of this EVA comprises triangle or quadrangle or the pentagon that has the arc limit.

Said neonychium and cloth are through heat seal together.

Edge butt joint or overlap joint between the said flexible glue piece.

Realize that method of the present invention is:

A: earlier with the flexible glue piece with injection moulding process moulding required form;

EVA on chip is cotton, be washed into required form with the produced cutting die of radium-shine cutting;

TPU sheet on chip and BEMIS PU film are cut into specific dimensions;

With " high frequency blanching " process, TPU sheet and BEMIS PU film integral are fused into a composite sheet again;

B: the flexible glue piece is inverted on the metal die of making in advance;

To put into the flexible glue piece towards good EVA cotton;

Prefabricated TPU sheet and BEMIS PU film composite sheet are put in the superiors;

With high frequency blanching process, with specified temp and energy, composite sheet and bottom flexible glue piece whole piece periphery are merged comprehensively, become a neonychium;

C:,, become complete moulding neonychium with the produced cutting die trimming of radium-shine cutting with neonychium;

D: complete moulding neonychium is inverted on the metal die of making in advance;

Required cloth is put on the ad-hoc location;

With high frequency blanching process, with specified temp and energy,, merge in the whole piece periphery with complete moulding neonychium and cloth comprehensively, become a complete neonychium on cloth.

Technical scheme of the present invention also comprises clothes class clothing; Neonychium like coat, trousers, underwear, underpants, footgear and cap etc.; The structure of this neonychium is same as described above, this neonychium be fixedly arranged on clothes class clothing the position should to be subject to impact site corresponding with human body.

This protection is paid somebody's debt and expected repayment later and can be used on other object that need protect human body.

The beneficial effect that the present invention has: have good impact resistant effect, simple in structure, cost is low, easy to use, comfortable etc.

The specific embodiment

Be described further below in conjunction with the accompanying drawing specific embodiments of the invention:

As shown in Figure 1, for neonychium 1 and cloth 2 are combined as a whole through mould and high frequency blanching.Neonychium 1 is made up of flexible glue main shell layer, the cotton layer of shock-absorbing and film composite bed.Flexible glue main shell layer is made up of 1-6 flexible glue piece 11, and the cotton layer of shock-absorbing is made up of 1-6 EVA cotton 12, and film composite bed 13 is made up of TPU sheet 131 and BEMIS PU film 132.

Flexible glue piece 11 is consistent with the shape of EVA cotton 12, is triangle or quadrangle or the pentagon etc. that have the arc limit, quantitatively also is identical.

Embodiment 1

Make neonychium.

Earlier with the flexible glue piece with injection moulding process moulding required form (4 block-shaped differences, the triangle that has an arc limit that varies in size);

EVA on chip is cotton 2., be washed into required form (identical) with the produced cutting die of radium-shine cutting with the flexible glue piece;

3. TPU sheet on chip and BEMIS PU film are cut into specific dimensions;
