Description
Technical field
Technical field is the functional treatment of textile material under the present invention, particularly a kind of method of utilizing plasma technique fabric face to be carried out metalized.
Background technology
Metallized fabrics is a kind of composite, and the fabric through metalized has permanent antistatic property; Absorb the electromagenetic wave radiation performance; Highly reflective to radar wave; Electric radiation property in low pressure range, to ultraviolet ray and ultrared reflection and absorption, performance such as fire-retardant.In addition, metallized fabrics can be by the spectacular gloss of metal improving the aesthetic effect of clothes, and by the reflecting effect of metal, improve the clothes heat insulating ability.Therefore, has potential huge applications prospect.
At present, fabric face metallized method mainly contains vacuum deposition method (also claiming the vacuum plating), electroless plating method.
Vacuum moulding machine is that the fabric after handling is placed under the vacuum condition, and the metal that gasifies is deposited on basic surface, forms uniform coating.Its technical process is fairly simple; Yet; The metallized fabrics that makes with this method, because the dirt that slurry agent, finish class and fiber surface that matrix uses in manufacture process adhere to, foreign matter etc. cause between matrix and the metal a little less than the adhesion, metal level is prone to peel off and comes off.Through before the vacuum plating, matrix is carried out kiering or washing, though can improve the adhesion between matrix and the metal level, process is complicated, the result is still unsatisfactory.
Chemical plating is that sample fabric is carried out activation processing in containing the acid metal salt activating bath of excess activation metal ion, after cleaning, carries out alkali treatment again.In the alkalinous metal salting liquid, invaded stain at last several minutes, and can form the thick metal level of 0.15～0.2um at fabric face.Through the metallized fabrics that chemical plating method makes, though adhesion is strong between fibrous matrix and the metal level, process is complicated, the problem of environmental pollution that also exists liquid waste processing to bring simultaneously.
For overcoming between the matrix that exists in the above method and the metal level a little less than the adhesion shortcoming with contaminated environment; Chinese patent CN1058538C " fabric face metallized treatment technology and equipment and product " a kind of Low Temperature Plasma Treating matrix that utilizes disclosed; So that fabric is produced corrasion, improve the method for the adhesion of matrix and metal interlevel.This method after Low Temperature Plasma Treating, is carried out vacuum aluminum-coated to it fabric again.Though through plasma etching, the adhesion of matrix and metal level is improved, still there is following shortcoming in this method:
1. only utilized the corrasion of air low temperature plasma in the Low Temperature Plasma Treating process.Promptly through etching, make the smooth surface of the matrix coarse injustice that becomes, combining between metal level and matrix is to be improved through physical action, its raising degree is restricted.
2. the process of vacuum drying of fabric is located at after the Low Temperature Plasma Treating; So just might be owing to the free water that exists in the fabric in the Low Temperature Plasma Treating process, the existence of adsorbed water and some other volatile impurity causes the atmosphere of plasma not control, and influences the stability of treatment effect and product quality; And by the same token; The vacuum of system is difficult for improving, and prolongs the non-cutting time that vacuumizes, and increases cost.
3. the method for vacuum plating is adopted in the generation of metal coating, so still there is the shortcoming of vacuum plating.
Summary of the invention
The objective of the invention is to overcome the deficiency that method that the above-mentioned fabrics surface metalation handles exists; Provide a kind of metal coating that can improve greatly to combine fastness, enhance productivity, reduce production costs, the method for the fabric face metallized processing of non-environmental-pollution with fabric substrate.
For achieving the above object, the technical scheme that the present invention adopted is: accomplish calendering, vacuumize, Low Temperature Plasma Treating to fabric earlier, carry out the processing of following steps again:
(1) with inorganic metal salt, polymer dissolution in organic solvent or water, be coated on the fabric substrate surface, form the transition zone to be restored of combining closely behind the drying and forming-film with fabric face;
(2) with the mist of hydrogen or hydrogen and inert gas as working gas, above-mentioned fabrics surface transition rete to be restored is carried out plasma deoxidization handles, obtain the surface metalation fabric.
Above-mentioned inorganic metal salt is a kind of in nitrate, sulfate, hydrochloride, acetate or the sulfide of metal A u, Ag, Cu, Fe, Ni, Co, Pt, Mo, and the hydrate of above-mentioned inorganic metal salt.
Above-mentioned polymer is a kind of in polyester, polyamide, polyolefin polymers or polyvinyl alcohol, the polyacrylonitrile.
Compared with prior art; Fabric face metallized method of the present invention is owing to adopted the technology of Low Temperature Plasma Treating, the energetic ion corrasion under the vacuum plasma state; Be that base cloth surface hinders lower-molecular substances such as the slurry agent that combines with metal, finish to volatilize; Remove the dirt and the foreign matter of fiber base cloth surface attachment, and can make that fiber surface is uneven, help improving the adhesion between fabric base cloth and the coating; Simultaneously, utilize the activity of the energetic ion of vacuum plasma, make fabric self surface receive high-octane action of plasma and modification takes place, the surface generates active group, to increase the compatibility of inorganic metal salt-polymer complexes coating and matrix; Again because adopted the plasma deoxidization in low termprature method from inorganic metal salt-polymer complexes coating that fabric face applies, to restore the technology of metal simple-substance; Metal level can be combined with fabric substrate with chemical bond, can improve the fastness that combines between fabric base cloth and the metal level greatly.Also because technical scheme of the present invention, processing temperature low (room temperature), technology simply, need not increase special process equipment, thereby reduced production cost, production efficiency is improved, and the acyclic pollution of technology according to the invention border.
Technology according to the invention is equally applicable to the surface metalation of fiber and handles.
