Embodiment 1

[0026] A completely biodegradable polybutylene succinate filament, wherein the component of the polybutylene succinate filament is 100% polybutylene succinate.

[0027] The preparation method of the above-mentioned fully biodegradable polybutylene succinate filament, comprising:

[0028] (a) Purchase polybutylene succinate (PBS) slices from the market. After the slices are pre-crystallized, they enter the drying tower and use a vacuum drum dryer to dry the PBS slices. The drum of the drum is slightly inclined. And can rotate the cylinder, the wet slices enter from the upper part of one end, and the dry slices are collected from the lower part of the other end. The hot air enters from the feed end or the discharge end, and is discharged from the upper part of the other end. There is a forward lifting board in the cylinder, so that the slices are continuously picked up and sprinkled during the rotation process in the cylinder, so that they can fully contact with the hot air flo...

Embodiment 2

[0034] A completely biodegradable polybutylene succinate filament, wherein the component of the polybutylene succinate filament is 100% polybutylene succinate.

[0035] Above-mentioned a kind of preparation method of fully biodegradable polybutylene succinate long filament comprises:

[0036] (a) Buy polybutylene succinate (PBS) slices from the market, and the slices first enter the pre-crystallizer (whether to pass through the crystallizer is selected according to the material conditions), and then enter the drying tower, using a vacuum drum The dryer dries the PBS slices. The drum of the drum is a slightly inclined and rotatable cylinder. The wet slices enter from the upper part of one end, and the dry slices are collected from the lower part of the other end. The hot air enters from the feed end or the discharge end, and is discharged from the upper part of the other end. There is a forward lifting board in the cylinder, so that the slices are continuously picked up and sp...

Abstract

The invention provides a completely biodegradable poly(butylene succinate) filament, and relates to the technical field of fibers. The filament comprises 100% of poly(butylene succinate). The filament provided by the invention overcomes the defects of poor permeability of polyester and nylon and easy aging of polypropylene, and has the characteristics of softness, comfort, easy caring and easy dyeing of natural fiber; the fabric woven from the fiber has excellent performances such as light weight, skin friendliness, breathability, green and environment-friendliness, especially the completely biodegradable property of the filament caters to the development ideas of soil protection and low carbon environmental protection promoted in the society.

Description

technical field [0001] The invention relates to the field of fiber technology, in particular to a fully biodegradable polybutylene succinate filament. Background technique [0002] Completely biodegradable plastics maintain the same level of function as existing plastics during use. After use, they can act on microorganisms such as bacteria, fungi, and seaweed in nature, and finally decompose into inorganic polymer materials such as water and carbon dioxide, thereby preventing environmental pollution. It plays a role in protecting the soil and the environment, so it is called "green plastic". Completely biodegradable plastics can be divided into microbially synthesized degradable plastics, natural product degradable plastics and chemically synthesized degradable plastics from the composition of raw materials and preparation methods. [0003] Chemically synthesized degradable plastics can be divided into aliphatic polyesters and aromatic polyesters. At present, aliphatic po...
