Embodiment 1

[0022] Choose the raw material of following parts by weight:

[0023]

[0024] The PBS material, the PLA material, the PPC material, the antioxidant and the light stabilizer are stirred and mixed at a speed of 40 rpm in a mixer. Then it is processed in a twin-screw extruder. During processing, the raw materials are melt-blended at a temperature range of 150° C. and 40 rpm, and then extruded and granulated. It is then melt-spun to make composite fibers. The spinning range of the conjugate fiber is 1.56dtex.

[0025] Carbon fibers with a spinning range of 1.56dtex are selected for blending with composite fibers to make biodegradable fibers. When blending composite fibers and carbon fibers, the ratio of composite fibers to carbon fibers is: 90% composite fibers and 10% carbon fibers.

Embodiment 2

[0027] Choose the raw material of following parts by weight:

[0028]

[0029]

[0030] The PBS material, the PLA material, the PPC material, the antioxidant and the light stabilizer are stirred and mixed at a speed of 70 rpm in a mixer. Then it is processed in a twin-screw extruder. During processing, the raw materials are melt-blended at a temperature range of 220° C. and 70 rpm, and then extruded to pelletize. It is then melt-spun to make composite fibers. The spinning range of the conjugate fiber is 2.65dtex.

[0031] Carbon fibers with a spinning range of 2.65dtex are selected for blending with composite fibers to make biodegradable fibers. When blending composite fibers and carbon fibers, the ratio of composite fibers to carbon fibers is: 95% composite fibers and 5% carbon fibers.

Embodiment 3

[0033] Choose the raw material of following parts by weight:

[0034]

[0035] The PBS material, the PLA material, the PPC material, the antioxidant and the light stabilizer were stirred and mixed at a speed of 55 rpm in a mixer. Then it is processed in a twin-screw extruder. During processing, the raw materials are melt-blended at a temperature range of 190° C. and 55 rpm, and then extruded to pelletize. It is then melt-spun to make composite fibers. The spinning range of the conjugate fiber is 1.56dtex.

[0036] Carbon fibers with a spinning range of 2.65dtex are selected for blending with composite fibers to make biodegradable fibers. When blending composite fibers and carbon fibers, the ratio of composite fibers to carbon fibers is: 93% composite fibers and 7% carbon fibers.

Abstract

The invention relates to the technical field of high-polymer material and concretely relates to an environment-protecting degradable fiber. The fiber is composed by mixing of PBS material, PLA material, PPC material, anti-oxidant and light stabilizing agent via a stirring machine, particles production by a double-screw extruder and melting spinning. Carbon fibers and composite fibers are blended to produce degradable fibers. During blending of the PBS and PLA material, PPC material is added and great compatibility is achieved; the degradable fibers can be achieved via blending between the carbon fibers and the composite fibers; during the use, the environment-protecting degradable fiber possesses great corrosion resistance and long service life; and the environment-protecting degradable fiber possesses strong degradation capability and can protect the environment and save energy.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a degradable fiber. Background technique [0002] PBS (polybutylene succinate) is easily decomposed and metabolized by various microorganisms in nature or enzymes in animals and plants, and finally decomposed into carbon dioxide and water. It is a typical fully biodegradable polymer material with good biological properties. Compatibility and bioabsorbability. At the same time, a large number of methylene structures in the main chain of PBS make it have similar mechanical and physical properties to general-purpose polyethylene materials, and are suitable for various processing techniques such as blown film and hollow container, extrusion sheet, spinning, injection molding, etc. It can be used to prepare various fully biodegradable polymer products. However, the usual PBS has low molecular weight, low processing temperature and low viscosity, and the mechanical properti...
