The purpose of this invention is to provide a kind of core-skin composite polypropylene fiber that contains ginkgo biloba p.e, when with 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.
Polypropylene fibre with health care provided by the present invention is a kind of core-skin composite fiber, the core-skin ratio is 60/40～80/20, cortex is a polypropylene, the core silk is for containing the polypropylene of ginkgo biloba p.e equably, the content of ginkgo biloba p.e in the core silk is 0.05～10wt.%, is preferably 0.1～7.5wt.%.
This ginkgo biloba p.e is for mainly containing the mixture of GINKGO BILOBA EXTRACT class and ginkgolide compound, in this mixture the content of gingkgo flavonoids be＞content of 20wt.%, ginkgolide compound is＞4wt.%.
Fiber can be made into the pre-oriented yarn POY that filament number is 1.0～4.0dtex, or further is processed into drafted fibre DT or elastic filament DTY that filament number is 0.5～3.0dtex, perhaps makes the staple fibre that fiber number is 1.0～4.0dtex.
Also can contain the far-infrared radiation ceramic powder equably in the fibrocortex, the content of far-infrared radiation ceramic powder in cortex is 5～15wt.%.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 fibrocortex 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 of fiber mainly comprises granulation and spinning two parts.
Granulation process is that ginkgo biloba p.e or ginkgo biloba p.e or far-infrared ceramic powder is warm equably in polypropylene particles, adopts screw extruder to carry out the granulation of blend heating and melting usually, and heating-up temperature is 150～200 ℃.Spinning properties in order to ensure fiber, the granularity of ginkgo biloba p.e or far-infrared ceramic powder and degree of scatter are very important, ginkgo biloba p.e must be selected the Powdered medicinal extract that is easy to disperse, and require average particulate diameter＜1 μ of ginkgo biloba p.e or far-infrared ceramic powder, wherein＞2 the particle requirement of μ is less than 5%.
Usually need to add an amount of dispersant in the granulation process, dispersant can be selected low-molecular-weight wax, higher fatty acids or high-grade aliphatic ester etc., the addition of dispersant is decided on the amount of ginkgo biloba p.e or far-infrared ceramic powder, and following proportioning is that the present invention recommends:
(A or B): C=1: (0.5～40)
In the proportioning:
The A=ginkgo biloba p.e
The B=far-infrared ceramic powder
The C=dispersant
The content of ginkgo biloba p.e can be made directly as the spinning material of core silk by required scope in the particle, also can be made into the higher master batch of content, then with the common pp material blend spinning material as the core silk.When making master batch, ginkgo biloba p.e content is advisable with (5～20) % (percentage by weight) in the master batch, and the degree of scatter of additive will decrease during too high levels.
In like manner, the content of far-infrared ceramic powder can be made directly as the spinning material of cortex by required scope, also can be made into the higher master batch of content, then with the common pp material blend spinning material as cortex.When making master batch, master batch mid and far infrared ceramic powders content is advisable with (10～30) % (percentage by weight), and the degree of scatter of additive will decrease during too high levels.
In addition, generally also should add an amount of antioxidant and molecular weight regulator in the spinning material of cortex and core silk, this is identical with the requirement that spinning has common polypropylene fibre now.
Conventional molten spinning is then adopted in spinning, and filament spinning component adopts the core-skin composite component, and the core-skin ratio is controlled to be 60/40～80/20, and spinning temperature is generally 220～280 ℃, and winding speed is generally 800～2800m/min.
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.
Positive effect of the present invention has provided a kind of new core-skin composite polypropylene fiber with health care, the ginkgo biloba p.e medicinal component that contains in the fiber can discharge under tepid state slowly, and is absorbed by human body by the respiration of human skin.And because the ginkgo biloba p.e medicinal component is present in the core silk of core-skin composite fiber, be difficult for losing because of washing.Make the fabric that makes produce far infrared radiation as adding an amount of far-infrared radiation ceramic powder in the fibrocortex, 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.
