SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel degradable biological fiber possesses the advantage of environmental protection, and it is big to have solved current artificial fiber degradation degree of difficulty, and difficult degradation easily causes the pollution to the environment, is not conform to the problem of the social demand of environmental protection.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel degradable biological fiber, includes the fibre body, the fibre body includes the inner core layer, the surface cladding of inner core layer has the enhancement layer, the surface cladding of enhancement layer has the superficial layer, the surface cladding of superficial layer has the waterproof layer.

Preferably, the inner core layer is made of polylactic acid fiber material.

Preferably, the reinforcing layer is made of kraft paper material.

Preferably, the surface layer is made of PLA fibers.

Preferably, the waterproof layer is made of a high polymer material.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses a cooperation of inner core layer, enhancement layer, superficial layer and waterproof layer is used, owing to all adopt degradable material as the main raw materials, so possess good degradability, compare in traditional artificial fiber, this product degradation degree of difficulty is little, and easy degradation can not cause the pollution to the environment, accords with the social demand of environmental protection.

2. The utility model discloses an adopt the interior sandwich layer that polylactic acid fiber material made, can make it possess good degradability, the better degradable nature of this product of having guaranteed, through the enhancement layer that adopts kraft paper material to make, can increase the mechanical strength of this product, the better life of this product of having guaranteed, superficial layer through adopting the PLA fibre to make, can make this product possess good heat resistance and ultraviolet resistance function, wearability is good, through adopting the waterproof layer that macromolecular material made, make it possess good degradability when waterproof, the better practicality of this product of having guaranteed.
