[0043] Example of preparation method of composite polyester

[0044] The embodiment of the present invention provides a preparation method of composite polyester for preparing the above-mentioned composite polyester, which specifically includes the following steps:

[0045] Preparation of microcapsule wall material hydrosol: edible natural polymer materials are stirred and dissolved in hot water, and the insoluble matter is filtered out after cooling to room temperature to obtain microcapsule wall material hydrosol. Specifically, the edible natural polymer material is stirred and dissolved in hot water at 70-100°C. The stirring is usually carried out in a blender. The stirring speed is 150-200r / min. After that, the original stirring speed is used at a temperature of At a specific temperature of 50-75°C, stirring at a constant temperature for 1-12h, and filtering out insoluble matter after cooling to room temperature to obtain a microcapsule wall material hydrosol.

Abstract

The invention discloses composite polyester and a preparation method thereof. The composite polyester comprises a fiber body and microcapsules uniformly formed in the fiber body; each microcapsule comprises a microcapsule core material and a microcapsule wall material coated outside the microcapsule core material; the microcapsule core material comprises the following components in percentage by weight of 20-40 wt% of polyester enzyme bacteria, 10-60wt% of mixed plant oil and 10-20wt% of sucrose ester; the polyester enzyme bacteria can be metabolized to generate polyester enzyme; and the microcapsule wall materials are edible natural polymer materials. The preparation method of the composite polyester comprises the following steps of preparing microcapsule wall material hydrosol, preparingthe polyester enzyme bacteria, preparing a microcapsule core material water emulsion, preparing the microcapsules and preparing the polyester. The composite polyester obtained by adopting the technical scheme has high stability in the fiber body in the microcapsule, and the composite polyester product can attract microorganisms in the environment to eat the micro-fibers after being discarded, sothat the problem that the polyester cannot be degraded and the hidden danger of the ecological environment exists is solved.

Description

Technical field [0001] The invention relates to the technical field of polyester, in particular to a composite polyester and a preparation method thereof. Background technique [0002] PET fiber, namely PET (polyethylene terephthalate), is currently the most widely used polyester microfiber. The fiber raw materials used in its current production are all derived from petrochemical production, and its consumption rate of resources is compared High, every year we produce a large amount of waste clothes directly discarded in the natural environment, most of which are directly buried in the soil for disposal, but because the traditional polyester microfiber is a natural inert fiber, it is in the soil It takes two to three hundred years to degrade. These non-degradable polyester microfibers will greatly harm the ecological environment. The non-degradable polyester microfibers in the soil will gradually flow into the ocean, which accounts for 71% of the global area, with the impact of r...
