Dacron macrobiological fiber containing ginkgo, rose, camellia, pomegranate and kudzu root and preparation method thereof

Technical Field

The invention relates to the field of fibers, in particular to a terylene macrobiotic fiber containing gingko, rose, camellia, pomegranate and kudzu root and a preparation method thereof.

Background

The ginkgo is a perennial deciduous tree of the genus ginkgo of the family ginkgoaceae, has a name of 'activating stones', has medicinal values of different degrees in leaves, fruits, pollen, seed coats, seed kernels, fruit stalks, roots and other parts, and is a traditional Chinese medicine for promoting blood circulation and removing blood stasis. The flavone and its glycosides, terpene lactones, organic acids, alkaloids, amino acids, isopentenol, steroids contained in semen Ginkgo have wide pharmacological activities including antitumor, antioxidant, antiinflammatory, antibacterial, antiviral, hepatoprotective, platelet aggregation inhibiting, and neuroprotective effects. Roses, namely roses, are perennial rosebush rosette belonging to the genus Rosa of the family Rosaceae, and have high ornamental value due to beautiful flower type and aromatic smell; in addition, the rose also contains more than 300 chemical components, wherein the volatile oil, the flavone, the polysaccharide, the phenolic acid, the alkaloid, the hemiterpenoid, the polysaccharide and the like have the effects of regulating blood, relieving pain, protecting liver, benefiting gallbladder, promoting qi circulation, relieving depression, resisting oxidation, resisting bacteria and resisting viruses. The camellia is a evergreen broadleaf woody plant of the genus camellia of the family theaceae, belongs to one of ten famous flowers in China, is used for viewing and beautifying the environment, is rich in chemical components such as polyphenol, flavone, triterpenes and organic acid, and has various pharmacological functions of bacteriostasis, hemostasis, inflammation diminishing, oxidation resistance and the like. The pomegranate is a variety of pomegranate, and the pomegranate fruit is rich in vitamin C, pomegranate polyphenol, anthocyanin and the like, so that the pomegranate fruit has the effects of expelling toxin, resisting oxidation, promoting the production of body fluid to quench thirst, relieving diarrhea and stopping bleeding. The kudzu root is the dried root of Pueraria lobata Ohwi of Leguminosae, and its main chemical components are isoflavone (mainly including puerarin, daidzein, daidzin, etc.), triterpenes, coumarin, puerarin, alkaloid and other compounds, starch and amino acids, and has good effects in resisting oxidation and regulating circulatory system.

Polyester fiber, also called polyester fiber, is a synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and dihydric alcohol, is called PET fiber for short, and belongs to a high molecular compound; as the first large synthetic fiber, it has not only the advantages of excellent stretch and anti-shrinkage properties, high elastic modulus and breaking strength, good resilience, good thermoplasticity, heat and light resistance, stable size, etc., but also is inexpensive, and thus is widely used in the clothing industry; the polyester fiber is divided into filament and short fiber, and the short fiber can be generally made by cutting filament. The large biological fiber is an active fiber with biological function produced by adding bioactive molecules into fiber (cotton, hemp, wool, silk, viscose, polyester, nitrile, nylon and the like) for modification. Therefore, the polyester macrobiological fiber prepared by modifying the polyester fiber by utilizing the bioactive molecules in the ginkgo, the rose, the camellia, the pomegranate and the kudzuvine root has the effects of promoting blood circulation, removing blood stasis, relieving pain, stopping bleeding, resisting inflammation, resisting bacteria and the like.

In the prior art, patent document with an authorization publication number of CN103541039B can be referred to, and discloses multifunctional modified polyester staple fibers, wherein the mass percentage of functional master batches in the polyester staple fibers is 1-10%; the functional master batch comprises the following raw materials in percentage by mass: 1-10% of nano bamboo charcoal, 1-20% of coffee carbon, 1-5% of functional reagent and the balance of PET slices, and the preparation method comprises the following specific steps: (1) preparing coffee charcoal; (2) micronizing; (3) preparing nano coffee carbon powder and nano bamboo charcoal powder containing functional reagents; (4) preparing functional master batches: vacuum drying the nano-scale coffee carbon powder, the nano-scale bamboo charcoal powder and the PET slices obtained in the step (3) at the temperature of 80-120 ℃ for 12-24 hours, extruding by using a screw at the temperature of 200-260 ℃, and then cutting into granules by using a granulator to obtain functional master batches; (5) blending and spinning: and (3) carrying out blending spinning on the functional master batch and the PET chips by a melt spinning device, wherein the screw temperature is 200-320 ℃, the spinning speed is 600-1500 m/min, the drafting temperature is 70-160 ℃, and the drafting multiple is 2-4 times, so as to obtain the multifunctional modified polyester staple fiber. The modified polyester staple fiber prepared by the method has large specific surface area, stronger adsorption capacity, antibiosis, deodorization, moisture absorption, drying and good conductivity; and has bamboo carbon and anion emission functions.

However, the terylene macrobiotic fiber is prepared in two steps: the preparation, blending and spinning of the functional master batches are carried out by a screw extrusion process, and the temperature of the screw is usually more than 200 ℃; when the extracts of ginkgo, rose, camellia, pomegranate and kudzu root added into the polyester fiber are subjected to a screw extrusion step in the preparation process, the biological activity of active ingredients in the extracts of the ginkgo, rose, camellia, pomegranate and kudzu root is easily damaged at the temperature of more than 200 ℃, so that the functionality of the prepared polyester macrobio-fiber is reduced.

Compared with the polyester macrobio fiber in the comparative example 1, the polyester macrobio fibers prepared in the examples 1 to 3 have breaking strength obviously higher than that of the comparative example 1 and are improved along with the increase of the addition amount of each material, but the polyester macrobio fibers prepared in the examples 1 to 3 have breaking elongation lower than that of the comparative example 1 and are reduced along with the increase of the addition amount of each material; the molecular weight of the microcapsule is increased and a net structure is formed on the surface when a large amount of nano porous heat insulating materials are combined on the outer surface of the microcapsule under the action of the silane coupling agent, so that the difficulty of deformation of the microcapsule during mechanical extrusion is increased, the mechanical strength of the microcapsule is improved, the breaking strength of the polyester macrobio fiber is improved, and the breaking elongation of the polyester macrobio fiber is reduced.

Compared with the polyester macrobio fiber in the comparative example 1, the polyester macrobio fibers prepared in the examples 4 to 5 have breaking strength obviously higher than that of the comparative example 1 and are improved along with the increase of the addition amount of each material, but the polyester macrobio fibers prepared in the examples 4 to 5 have breaking elongation lower than that of the comparative example 1 and are reduced along with the increase of the addition amount of each material in the functional agent; the molecular weight of the microcapsule is increased and a net structure is formed on the surface when a large amount of nano porous heat insulating materials are combined on the outer surface of the microcapsule under the action of the silane coupling agent, so that the difficulty of deformation of the microcapsule during mechanical extrusion is increased, the mechanical strength of the microcapsule is improved, the breaking strength of the polyester macrobio fiber is improved, and the breaking elongation of the polyester macrobio fiber is reduced.

Compared with the polyester macrobio fibers in the comparative example 1, the polyester macrobio fibers prepared in the examples 6 to 7 have breaking strength which is significantly higher than that of the comparative example 1 in the examples 6 to 7, but the breaking elongation of the polyester macrobio fibers prepared in the examples 6 to 7 is similar to that of the comparative example 1; the explanation is mainly due to the following two aspects: on one hand, when a large amount of nano porous heat insulating materials are combined on the outer surface of the microcapsule under the action of the silane coupling agent, the molecular weight of the microcapsule is increased, and a net structure is formed on the surface, so that the difficulty of deformation of the microcapsule during mechanical extrusion is increased, the mechanical strength of the microcapsule is improved, the breaking strength of the polyester macrobio fiber is improved, and the breaking elongation of the polyester macrobio fiber is reduced; on the other hand, the carbon fiber powder is bonded to the outer surface of the microcapsule under the action of the silane coupling agent, so that the mechanical strength of the microcapsule is further improved, and the high toughness of the carbon fiber powder can compensate the reduction degree of the elongation at break caused by the mechanical strength, so that the elongation at break of the polyester macrobio fiber is maintained.
