Abstract
The invention discloses a fully-degradable composite filament and a manufacturing method and application thereof, and relates to the technical field of fiber preparation, the fully-degradable composite filament comprises an outer surface layer and an inner core layer, the outer surface layer wraps the surface of the inner core layer, the inner core layer is of a hollow tube structure, the inner core layer is a single-layer fiber made of a high-melting-point polylactic acid fiber material, and the outer surface of the inner core layer is coated with the polylactic acid fiber material. The outer surface layer is a single-layer fiber made of a low-melting-point polylactic acid fiber material; the melting point of the inner core layer is higher than that of the outer surface layer; the material composition of the composite filament is'skin (low-melting-point PLA) + core (high-melting-point PLA) ', and the technical purpose that the composite filament has a complete degradation function is achieved by utilizing the degradable characteristic of PLA.
Description
technical field [0001] The invention relates to the technical field of fiber filament preparation, in particular to a fully degradable composite filament and its manufacturing method and application. Background technique [0002] Existing water-absorbing fiber rods are compounded by monofilaments of pure PET (polyester) or PP (polypropylene). Make the inside of the fiber filament tightly bonded to form a certain elastic rod-like structure, [0003] The above-mentioned prior art has the following problems: PET (polyester) or PP (polypropylene) materials do not have the degradation function, and cannot be applied to the current environmental protection requirements. Contents of the invention [0004] The purpose of the present invention is to provide a fully degradable composite filament and its manufacturing method and application, so as to solve the above-mentioned problems in the prior art, so that the composite filament has a fully degradable function. [0005] In orde...
