A kind of super amphiphilic fabric fibre and method for making and application
The present invention relates to a kind of fabric fibre and method for making and application through plasma surface treatment.
The plasma treated surface modification is to utilize the plasma of certain atmosphere and polymer surface to interact, introduce new group at polymer surface (thickness of several dusts to tens nanometer), significantly change the parent/hydrophobicity of material surface, cementability, printing and dyeing property etc., but, can under the prerequisite that does not change the material body performance, give the lubricant nature energy that inclines of material surface excellence because of it does not change the internal structure of material.The flat 11-335963 of Japan patent of invention (Te Open) a kind of method for preparing the long-lasting polyalkenes nonwoven fabric of high-hydrophilic is disclosed, its utilization feeds nitrogen under the vacuum of about 1Torr, with the pulse power, the impulse electric field (times of advent 5 μ s, frequency 5KHz, pulse 100 a μ s) laser discharge during 4KV, glow discharge during 6KV; 167% electric-field intensity is carried out plasma discharge processing 20s to the polyalkenes nonwoven fabric under the 10KV when beginning with above-mentioned discharge under same pressure then.U.S.'s patent of invention (application number: 5,777,436) disclose a kind of gaseous plasma electric discharge for preparing hydrophilic material; (application number: 5,804,263) the method decorative material surface that discloses a kind of utilization gamma-radiation (gamma radiation) and plasma polymerization (plasma polymerization) makes its possess hydrophilic property to U.S.'s patent of invention.
Though prepared material possesses certain hydrophilic or super hydrophilic effect in the above technology, does not possess super parents' effect.Super hydrophilic or super oleophylic is meant that water droplet or oil droplet (is standard with the vegetable oil) sprawl rapidly at solid surface energy, with the contact angle of the surface of solids less than 5 °.And super parents are meant when water droplet and oil droplet drop in the surface of solids, the surface of solids all can sprawl rapidly and with the contact angle on surface all less than 5 °.
The object of the present invention is to provide a kind of super amphiphilic fabric fibre through plasma surface treatment.
Another object of the present invention is to provide a kind of method for making of passing through the super amphiphilic fabric fibre of plasma surface treatment.
The present invention also aims to provide application through the super amphiphilic fabric fibre of plasma surface treatment.
A kind of super amphiphilic fabric fibre of the present invention, the size of its surperficial possess hydrophilic property group and the coexistence of lipophile group is in the convex-concave structure of 10~500nm, the processing that described fabric fibre has carried out its surface through the plasma spike.
The method for making of a kind of super amphiphilic fabric fibre of the present invention, carry out according to the following steps:
(1) undressed fabric fibre is put in the plasma machine vacuum tank, vacuumized and make air pressure reach 1~1 * 10
-3Torr;
(2) with 1~10
Ml/
MinFlow velocity feed pure O
2, N
2, NH
3, H
2Or any in the air, continued to vacuumize about 5~10 minutes;
(3) adjust a wage scale radio-frequency power to 30~100 watt, under plasma atmosphere to fabric fibre surface treatment 10s~10min;
(4) take out fabric fibre, dry getting final product in atmosphere.
A kind of super amphiphilic fabric fibre of the present invention, preparation technology is simple, wide accommodation.Only need a cover plasma instrument during preparation, and also do not have special requirement for fabric fibre.This super amphiphilic fabric fibre stable performance in addition, super parents' performance longer duration does not almost change in 3 months later on super parents' performances of placement.
As follows below in conjunction with its advantage and description of use:
(1) super amphiphilic fabric fibre of the present invention has the performance of super hydrophilic and super oleophylic, water droplet or oil droplet can be rapidly at its surface spreading and immerse the fabric fibre interior surface, thereby widened the scope of application of the coloring agent of this fabric fibre, and dyeing and enduring quality also are largely increased.
(2) super amphiphilic fabric fibre of the present invention has the performance of super hydrophilic and super oleophylic, and is ventilative, poisture-penetrability is better, and stable performance, can be used for various garment materials, especially various high-grade underwear fabrics.
(3) super amphiphilic fabric fibre of the present invention has the performance of super hydrophilic and super oleophylic, can be applicable to various clean type linings, especially is suitable for the more place of greasy dirt as making rag.
(4) super amphiphilic fabric fibre of the present invention is obtained by plasma surface treatment under given conditions, and sterilization processing has been passed through on its surface.For example: at internal diameter 0.07cm, in the capillary of long 8cm, put into 10,000 withered grass bacterium spores, through Cement Composite Treated by Plasma whole death rays after 15 minutes.And this fabric fibre has the performance of super hydrophilic and super oleophylic, to the good hygroscopicity of liquid, therefore can be used as medical fibre.
(5) method for making of super amphiphilic fabric fibre of the present invention is applicable to any fabric fibre.
The present invention is further detailed explanation below in conjunction with embodiment.
