Description
Technical field
The present invention relates to a kind of fiber surface-processing method, fiber surface nano functionalization processing methods such as particularly a kind of cotton, fiber crops, silk, hair.
Background technology
Along with the mankind to improving constantly that the functionalization such as comfortable, healthy, environmental protection of textiles require, the functionalization of fiber also becomes the theme of present fiber production.Functional fibre except that functional material is directly added to make in the raw material, by the back dressing liquid functionalization is carried out on its surface, making functional fibre also is the method for using always.People such as the KOURAI of the U.S. invent " the fine fiber of antibiotic propylene with photocatalytic activity " (patent No.: 6613828).Japan Patent Laid-pen52/92000, all be with fiber before dry and the lax technology of heat, the fiber that will be in the gelinite structure is handled with the aqueous solution of the slaine of antibacterial activity, and antibacterial activity salt is remained among the fiber; " nanometer silver anti-bacteria cloth and the industrialized producing technology thereof " that Jiang Jianhua etc. are announced is (open/notification number: as 1291667), also to be attached between the fiber of cloth and on the fiber with nano-Ag particles.Above-mentioned patented technology is surface absorption, and its function persistence, attachment anchorage all can not satisfy weaving and the requirement of using.
Summary of the invention
The objective of the invention is fiber surface to be handled,, solve the problem of fiber surface functional layer strong, durable, and a kind of fiber surface nano functionalization processing method is provided again with dressing liquid behind the nano functionalization with the Low Temperature Plasma Treating technology.
The present invention realizes that technical scheme that above-mentioned purpose is taked is to add deionized water with antiseptic nano powder or nano-anti static powder or nano flame retardant powder and dispersant to make nano functional solution; Place solution tank adding fatty alcohol to stir the nanometer softener and make the soft solution of nanometer; And, make nanometer emulsifying liquid with nano functional solution and the soft solution mixing of nanometer emulsifying; To introduce in the plasma treatment appts through pretreated fiber again, use microwave discharge, in blanket of nitrogen, handle; Fiber after the processing places the nanometer emulsifying liquid of treatment trough, with fatty acid for adjusting pH value dipping, carries out Cement Composite Treated by Plasma once more, with the oven dry of the fiber after the impregnation process, makes the surface nano functionalization fiber at last.
Wherein said fiber is cotton or fiber crops or silk or hair etc.
Above described fiber surface nano functionalization processing method follow these steps to carry out:
(1) gets 5～30 parts of antiseptic nano powder or nano-anti static powder or nano flame retardant powders, add 2～10 parts of dispersants, add deionized water again, be mixed with concentration and be 3%～12% nano functional solution for later use;

(3) the nano functional solution that above-mentioned steps (1) is made evenly mixes with the soft solution of nanometer that step (2) is made, and places high-shearing dispersion emulsifying machine, with stand-by behind 8000～10000rpm rotating speed homogeneous processing 20min;
(4) will introduce in the plasma treatment appts through pretreated fiber, use microwave discharge, in blanket of nitrogen, handle, microwave power 260～700W, pressure 20Pa handles 3～10min;
(5) fiber after the Cement Composite Treated by Plasma is placed treatment trough, put into the nanometer mixed solution after above-mentioned steps (3) homogeneous is handled, regulate pH=6～8 with aliphatic acid, impregnation process 3～10min under 20 ℃～50 ℃ temperature;
(6) fiber after will flooding enters in the plasma treatment appts once more, adopts step (4) to handle 3～5min;
(7) fiber after will handling imports drying unit, and bake out temperature is 60 ℃～120 ℃, and drying time is 10～20min, makes the nano functional fiber.
The innovation part of the invention process technique scheme is to select for use nano-functional material to be mixed with function solution, utilize the Cement Composite Treated by Plasma technology again, realization is to the etching roughening of fiber surface, and make fiber surface form a certain amount of active group, cause the function monomer glycerol polymerization, form firm crosslinked functional layer (seeing the SEM photo), make fiber have the functional effect of extraordinary lasting and wash resistant, rub resistance.Simultaneously, this technical process is put in order after being different from conventional textile auxiliary, pollution-free, nuisanceless, help health and environmental protection, and make Performance Level, the applicable situation of functional fibre, multi-functional function such as get both all is better than finishing fiber behind the conventional auxiliary agent, has improved the spinnability and the functional connotation of fiber and has promoted its ratio of performance to price and added value.
Description of drawings
Fig. 1 is the SEM photo on untreated silk fiber surface, its smooth surface, and the function thing is difficult in surface formation functional layer.
Fig. 2 is the SEM photo on the silk fiber surface after handling, and the etching of plasma makes the fiber surface roughening, and because its energy on the macromolecular chain of fiber, makes fiber surface easily carry out glycerol polymerization, forms firm functional layer.
