[0043] Example of the preparation method of composite polyester

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

[0045] Preparation of microcapsule wall material hydrosol: the edible natural polymer material is stirred and dissolved in hot water, cooled to room temperature and then filtered to remove insoluble matter to obtain the 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 mixer, and the stirring speed is 150-200 r / min. After that, the original stirring speed is used, and the temperature is At a specific temperature of 50-75°C, constant temperature stirring for 1-12h, cooling to room temperature and filtering out insoluble matter to obtain a hydrosol of the microcapsule w...

Abstract

A composite polyester fiber and a preparation method thereof have been disclosed. The composite polyester fiber includes a fiber body and a microcapsule uniformly formed in the fiber body; the microcapsule includes a microcapsule core material and a microcapsule wall material coated on the microcapsule core material; The capsule core material includes the following components by weight percentage: 20-40wt% of polyester enzyme bacteria, 10-60wt% of vegetable sesame oil, 10-20wt% of sucrose ester; polyester enzyme bacteria can metabolize to produce polyester enzyme; microcapsule wall material is edible of natural polymer materials. The preparation method of composite polyester comprises the following steps of preparing microcapsule wall material hydrosol, preparing polyester enzyme bacteria, preparing microcapsule core material water emulsion, preparing microcapsule and preparing polyester. The composite polyester obtained by the above technical solution has good stability in the presence of microcapsules in the fiber body, and the composite polyester product can attract microorganisms in the environment to eat the microfibers after being discarded, thus solving the problem that polyester cannot be degraded. However, there are problems that endanger the ecological environment.

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 the most widely used polyester microfiber at present. 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 will produce a large amount of waste clothes and discard them directly in the natural environment. Most of the waste clothes are directly disposed of through soil burial, but because the traditional polyester microfiber is a natural inert fiber, it is in the soil. It takes two or 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 w...
