The purpose of this invention is to provide a kind of manufacture method that contains the polypropylene fibre of ginkgo biloba p.e, polypropylene fibre that makes and natural fabrics such as cotton, wool, flax, or with artificial fibre blending such as terylene, acrylic fibers, polyamide fibre, viscose after, can make underwear, socks, sheet etc. and human body drapery that contacts next to the shin or bedding, the ginkgo biloba p.e medicinal component discharges lentamente in the fiber, and is absorbed by human body by the respiration of human skin.
Manufacture method with health care polypropylene fibre provided by the present invention its essence is and add additive ginkgo biloba p.e or ginkgo biloba p.e and far-infrared radiation ceramic powder that in fiber manufacture method comprises granulation and two processes of spinning:
1) additive ginkgo biloba p.e or ginkgo biloba p.e and far-infrared ceramic powder, dispersant, acrylic resin are mixed, adopt screw extruder to carry out raw material particle or the master batch that the granulation of blend heating and melting makes direct fabrics, heating-up temperature is 150～200 ℃
The raw material weight proportioning of additive is in the raw material particle of direct fabrics:
A∶B＝1∶(0～200)
And (A+B): C=1: (0.5～40)
The content of A is in the raw material particle of direct fabrics: 0.05～2wt.%;
The raw material weight proportioning of additive is in the master batch:
A∶B＝1∶(0～200)
And (A+B): C=1: (0.5～40)
The content of A+B is in the master batch: 5～30wt.%;
Wherein, A=ginkgo biloba p.e; The B=far-infrared ceramic powder; The C=dispersant;
2) with the raw material particle of the above-mentioned direct fabrics that obtain, or the mixture of master batch and plain polypropylene resin, melt spinning makes long filament or staple fibre in screw extruder after drying, the content of control ginkgo biloba p.e in fiber is 0.05～2wt.%, be preferably 0.1～1.5wt.%, the weight ratio of control ginkgo biloba p.e and far-infrared ceramic powder is 1: (0～200), spinning temperature are 220～280 ℃, and winding speed is 800～2800m/min.
Above-mentioned ginkgo biloba p.e is for mainly containing the Powdered ginkgo leaf medicinal extract of GINKGO BILOBA EXTRACT class and ginkgolide compound, in the medicinal extract content of gingkgo flavonoids be＞content of 20wt.%, ginkgolide compound is＞4wt.%, the average particulate diameter of Powdered ginkgo leaf medicinal extract and described far-infrared ceramic powder＜1 μ, wherein＞2 the particle requirement of μ is less than 5%.Above-mentioned dispersant can be selected low-molecular-weight wax, higher fatty acids or high-grade aliphatic ester.
The far-infrared radiation ceramic powder can be to take from a kind of in silica, zirconium dioxide, zirconium carbide, di-iron trioxide or the cupric oxide usually, or takes from wherein two or more mixtures.Adding an amount of far-infrared radiation ceramic powder in fiber is to make the fabric that makes produce far infrared radiation, with the fine blood circulation of further enhancing human epidermal, will more help the absorption of human epidermal to medicinal composition in the ginkgo biloba p.e like this.
The manufacturing technique of the antibacterial polypropylene fiber of other technology of spinning and prior art mid and far infrared polypropylene fibre, interpolation antimicrobial agent is basic identical.
Granulation process is that ginkgo biloba p.e or ginkgo biloba p.e and far-infrared radiation ceramic powder is warm equably in polypropylene particles, adopts screw extruder to carry out the granulation of blend heating and melting usually.Spinning properties in order to ensure fiber, the granularity of ginkgo biloba p.e and far-infrared ceramic powder and degree of scatter are very important, so Powdered medicinal extract that the ginkgo biloba p.e selection is easy to disperse, and require average particulate diameter＜1 μ of ginkgo biloba p.e and far-infrared ceramic powder, wherein＞2 the particle requirement of μ is less than 5%.
The master batch that granulation process is higher as the content that makes ginkgo biloba p.e or ginkgo biloba p.e and far-infrared ceramic powder, should with common acrylic resin co-blended spinning.When adopting this master batch method technology, the total content of ginkgo biloba p.e or ginkgo biloba p.e and far-infrared ceramic powder and dispersant is advisable with＜30wt.% in the master batch, and the degree of scatter of additive will decrease during too high levels.
In addition, sometimes as required, also add an amount of antioxidant and molecular weight regulator in the polypropylene spinning particle, this is identical with the requirement that spinning has common polypropylene fibre now.
According to different needs, fiber can be made into staple fibre, pre-oriented yarn POY, drafted fibre DT and elastic filament DTY, and the after-processing technology of staple fibre, drafted fibre DT and elastic filament is basic identical with existing similar polypropylene fibre processing technology.
Among the present invention, the addition of ginkgo biloba p.e and granulation, spinning temperature are key problem in technology.Because ginkgo biloba p.e is the mixture of compounds such as high boiling flavonoids, bisflavones and ginkgo lactones and middle low-boiling compound; so addition is too high or processing temperature is too high; easily make wherein low-boiling compound decomposes charing when melt pelletization or spinning; influence quality of fiber; fondant filter or component pressure rise too fast when making spinning; end breakage rate raises, the spinnability variation.In addition, the too high levels of ginkgo biloba p.e and far-infrared ceramic powder also can influence spinnability and fibre strength.
Positive effect of the present invention has provided the method that a kind of manufacturing has the polypropylene fibre of health care, the ginkgo biloba p.e medicinal component that contains in the fiber that makes can discharge under tepid state slowly, and is absorbed by human body by the respiration of human skin.Can make the fabric that makes produce far infrared radiation as in fiber, adding an amount of far-infrared radiation ceramic powder, can further strengthen the fine blood circulation of human epidermal, thereby more help the absorption of human epidermal medicinal composition in the ginkgo biloba p.e.
Because polypropylene fibre and other natural fabric and synthetic fiber have good blending spinning property, can with natural fabrics such as cotton, wool, flax, or with artificial fibre blending such as terylene, acrylic fibers, polyamide fibre, viscose, make underwear, socks, sheet etc. and human body drapery that contacts next to the shin or bedding.These draperys or bedding in use have unique health-care function to human body, and have certain antibiotic effect, and some skin disease is also had certain auxiliary curing effect.Though above-mentioned effect is not passed through strict clinical testing, according to the existing pharmacological experiments of ginkgo biloba p.e is not difficult to know by inference.
