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.
Its 150～200 ℃ of manufacture methods with health care core-skin composite polypropylene fiber provided by the present invention,
The weight percentage of directly making B in the cortex raw material particle is (5～15) %
The weight percentage of B is (10～30) % in the cortex master batch
B∶C=1∶(1～20)
B=far-infrared radiation ceramic powder
The C=dispersant
With the above-mentioned cortex raw material polypropylene particles that obtains, or master batch and plain polypropylene mix particles be as the spinning material of cortex, and the weight percentage of control cortex mid and far infrared radiation ceramic powder is (5～15) %.
Above-mentioned far-infrared radiation ceramic powder is to take from a kind of in silica, zirconium dioxide, zirconium carbide, di-iron trioxide or the cupric oxide, or for taking from wherein two or more mixtures, the average particulate diameter of far-infrared radiation ceramic powder＜1 μ, wherein＞2 the particle requirement of μ is less than 5%.
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.
Granulation process is that ginkgo biloba p.e or ginkgo biloba p.e or far-infrared ceramic powder is warm equably in polypropylene particles, in order to ensure the spinning properties of fiber, the granularity of ginkgo biloba p.e or far-infrared ceramic powder and degree of scatter are very important.So, require ginkgo biloba p.e to select the Powdered medicinal extract that is easy to disperse, and the average particulate diameter of ginkgo biloba p.e or far-infrared ceramic powder＜1 μ, wherein＞2 the particle requirement of μ is less than 5%, and adds an amount of dispersant.Dispersant can be selected low-molecular-weight wax, higher fatty acids or high-grade aliphatic ester etc., and the addition of dispersant is decided on the amount of ginkgo biloba p.e or far-infrared ceramic powder.
The content of ginkgo biloba p.e can have been made directly spinning material as the core silk by required scope in the particle, or makes 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 have been made directly spinning material as cortex by required scope, or makes 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).
