Problems solved by technology

[0004] The technology of bodhi extract as a plant modifier for fiber modification is still immature
Especially in the preparation technology of modified polyester fiber, the dispersion uniformity of the bodhi extract is poor during the preparation process, and the accumulation of the bodhi extract will greatly reduce the mechanical properties of the fiber, which will lead to weak functionality and difficulty in playing its due role
During the research and development process, the applicant found the following technical defects that were difficult to overcome: (1) Poor dispersion uniformity and high loss rate of Bodhi extract in the process of preparing polyester fiber; (2) Poor hygroscopicity of finished fiber; (3) Bodhi extract was used The polyester fiber prepared by extract modification has low mechanical strength; (4) Poor stability

Abstract

The invention provides a preparation method of ficus religiosa-containing polyester fibers. The preparation method comprises the following steps: preparing porous silicon dioxide microspheres; thoroughly mixing secondary distilled water with ethanol to prepare an ethanol solution; and adding hexadecyl trimethyl ammonium bromide into the ethanol solution, adding an ammonia solution as a catalyst, dropwise adding ethyl orthosilicate, baking solids after a reaction, and calcining the baked solids to obtain the porous silicon dioxide. The preparation method further comprises a step of preparing aporous molecular nest containing a ficus religiosa extract: adding porous silicon dioxide powder and an ethanol aqueous solution into a ball mill, and performing grinding, shearing and dispersing to obtain porous nano-material dispersion liquid; and shearing and dispersing a saturated aqueous solution of the ficus religiosa extract, the porous nano-material dispersion liquid, a coupling agent anda surfactant to obtain nano-material dispersion liquid containing the ficus religiosa extract, and volatilizing a solvent to obtain the dried porous molecular nest containing the ficus religiosa extract. A prepared fiber finished product is high in mechanical strength and good in hygroscopicity.

Description

technical field [0001] The invention belongs to the technical field of fiber manufacturing, and in particular relates to a linden-containing polyester fiber and a preparation method thereof. Background technique [0002] The basic composition of polyester is polyethylene terephthalate, the molecular formula is HO-H2C-H2C-O[-OC-Ph-COOCH2CH2O-]n, because there are a large number of ester groups in the molecular chain, it is called polyester fiber (PET ), the chemical structural formula of its long-chain molecule is H(OCH2CCOCO)NOCH2CH2OH, the relative molecular weight of polyester used for fibers is generally around 18000-25000, the molecular weight of wool-like polyester is low, and the molecular weight of industrial polyester is high. In fact, there are also small amounts of monomers and oligomers present. These oligomers have a low degree of polymerization and exist in a cyclic form. Polyethylene terephthalate can be obtained by polycondensation of terephthalic acid (PTA)...
