The linoleic acid of 0.1～20wt% is preferably comprised in the natural plant grease.
One or more in the preferred polyethylene terephthalate of the thermoplastic polymer, nylon 6, mutual-phenenyl two acid bromide two alcohol ester.
The invention also discloses a kind of fabric, contains above-mentioned flexible fibre in the fabric.
Specific embodiment
Natural plant grease is dispersed with the flexible fibre of the present invention.The addition of natural plant grease can make fiber surface be modified, and form small concavo-convex, to make and produce glutinous sense of touch with people's physical ability during skin contact after fabric, feel that fabric is soft, comfortable and easy to wear.
The content of natural plant grease accounts for 0.1～15wt% of fiber total amount in fiber.Natural plant grease content is less than if 0.1wt% in fiber, and the flexibility of fiber is bad；The content of natural plant grease is higher than if 15wt% in fiber, then the fibre forming property when mixture in thermoplastic polymer and natural plant grease prepares fiber is bad.From the aspect of synthesis in terms of the flexibility and fibre forming property two of fiber, the content of natural plant grease preferably accounts for 2～10wt% of fiber total amount in fiber of the present invention.
For the fiber for wearing medicated clothing is mainly used in, if the fusing point of natural plant grease in fruit fiber is more than 0 DEG C of even more high, oils and fatss can produce solidification in fabric when outside air temperature is less than the fusing point of natural plant grease, cause fabric also harder than General polymeric fibres, the feel and outward appearance of fabric are all deteriorated.Therefore, the present invention selects natural plant grease of the fusing point below 0 DEG C, the demand of wearing for alloing gained fiber to be adapted under any temperature, even if temperature is less than 0 DEG C, medicated clothing also will not be hardened due to the solidification of natural plant grease.
The flexible fibre containing natural plant grease of the present invention is worth by the blend Jing melt spinnings of thermoplastic polymer and natural plant grease, therefore the boiling point of selected natural plant grease must be able to meet the minimum requirements of spinning temperature.The present invention selects natural plant grease of the boiling point more than 200 DEG C, it is preferred that boiling point is more than 270 DEG C, can ensure that and be not in temperature resistance problem during high melt point thermoplastic polymer spinning, the waste of oils and fatss and the rising of cost also will not be produced due to the vaporization of natural plant grease.
The Oleic acid of 55～97wt% is preferably comprised in the natural oil of the present invention, Oleic acid has very strong moisture-retaining capacity, there is to human body skin excellent moistening effect when directly smearing；And used as unsaturated acids, Oleic acid also has the effect of anti-inflammation.Oleic acid is applied in fiber, it is also possible to give the function of the excellent moisturizing of fiber and antibacterial.
But used as single unsaturated acids, the thermostability of Oleic acid is bad, the problems such as being susceptible to change colour in spinning after with high melt point thermoplastic polymer mixed, decompose, therefore it is used to be subject to certain restrictions.Therefore, in order to relax the thermostability brought by Oleic acid in terms of uncertainty, the present invention natural plant grease in further preferably contain Squalene.Squalene is a kind of natural bioactive substance, the thermostability of natural plant grease can to a certain extent be improved after addition, the hardening that fiber and the fabric by made by fiber are produced in sizing heating process can also be improved simultaneously, make fiber and plant keep more preferable flexibility.
The content of Squalene preferably 0.1～3wt% in the natural oil.The flexibility of the thermostability and fiber/fabric of natural plant grease can not be effectively improved if Squalene content is too little, with the basic zero difference of the performance of the natural plant grease for not containing Squalene；Squalene content can make greatly very much dispersibility of the natural plant grease in thermoplastic polymer be deteriorated, and cause wire broken rate in spinning process to increase, and very big decline occurs in production efficiency, without real value.
In addition, the moisture pick-up propertiess in order to improve fiber, the further preferably linoleic acid containing 0.1～20wt% in the natural plant grease of the present invention.
Linoleic acid, with good hygroscopicity, but if too high levels, can suppress the heat-resisting effect of Oleic acid as unsaturated fatty acid in heating process, cause Oleic acid thermal decomposition occur, cause the fiber containing natural oil the problems such as changing colour occur indirectly.
