Abstract
The utility model discloses a polylactic acid fiber multilayer film. The polylactic acid fiber multilayer film is formed by high molecular weight polylactic acid fiber layers and low molecular weight polylactic acid fiber layers in an alternatively combined mode. The polylactic acid fiber multilayer film has the advantages of being reasonable in structure, fast to degrade, excellent in flexibility and the like.
Description
Technical field
The utility model relates to a kind of acid fiber by polylactic multilayer film.
Background technology
Electrostatic spinning technique prepares superfine fibre by electrostatic force as tractive force.In the electrostatic spinning process process, polymer solution is added to the high-pressure electrostatic of several thousand to several ten thousand volts, thereby produce a powerful electric field force between the receiving device of capillary and ground connection.When electric field force puts on liquid surface, will, at surperficial generation current, when jet moves from capillary end to receiving device, all hastening phenomenon can appear, this has also caused the stretching of jet in electric field, the final nanofiber that forms the nonwoven fabric shape on receiving system.
The acid fiber by polylactic film is current clinical response post-operation adhesion preventing material preferably, by electrostatic spinning technique, can prepare the acid fiber by polylactic film of similar nonwoven cloth material.The acid fiber by polylactic film has overcome fragility and the hardness of poly-lactic acid material itself fully, possesses clinical value preferably.But at present acid fiber by polylactic film used mostly is the poly-lactic acid in high molecular weight film clinically, and degradation time is slow, and pliability remains to be further improved.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and degradation time is fast, and the acid fiber by polylactic multilayer film of pliability excellence.
Technical solution of the present utility model is:
A kind of acid fiber by polylactic multilayer film is characterized in that: replace compound the composition by poly-lactic acid in high molecular weight fibrage and low molecular weight fibrage.
Described acid fiber by polylactic multilayer film has the fibrage composite construction that haves three layers at least.
The poly-lactic acid in high molecular weight fibrage has two layers at least; The low molecular weight fibrage has two layers at least.
Described poly-lactic acid in high molecular weight viscosity average molecular weigh is 150,000～200,000.Described low molecular weight viscosity average molecular weigh is 5000～30,000.
The utility model is rational in infrastructure, has degradation time faster, the excellent advantages such as pliability.
The accompanying drawing explanation
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of an embodiment of the utility model.
