Abstract
The present invention belongs to the field of functional fabric, and is especially antistatic wool fabric of fiber with surface nano structure and its preparation. After wool fabric is set inside low temperature plasma processing cavity, the pressure inside the cavity is first pumped to not higher than 10 Pa and then regulated with introduced non-polymerizing gas to 10-170 Pa and the wool fabric is discharged for low temperature plasma processing at power of 10-300 w for 1-60 min, so as to form nano level embossed structure in the surface of wool fiber to raise the amplexation force in wool fiber and reduce friction, to produce hydrophilic radical in the surface of wool fiber for fast escape of water and to obtain wool fiber with excellent antistatic performance. The said process produces excellent lasting antistatic effect.
Description
Technical field
The invention belongs to the functional manufacture field of textiles, relate in particular to fiber surface and have antistatic wool fabric of nanostructured and preparation method thereof.
Background technology
Textile material is the non-conductor of electricity, and they have very high ratio resistance.In friction process repeatedly, electric charge shifts at fiber surface, and powerful ratio resistance has hindered the quick loss of electric charge, so when friction component separated, fiber just had been with electric charge, forms electrostatic phenomenon.According to test, tangible electric-shock feeling will appear when having gathered 2000V static on the material, thereby the sense of discomfort that causes human body, but also make a large amount of impurity such as dust of textiles absorption reduce the quality of textiles easily, even become the inducement of imflammable gas burning, blast.
For many years, domestic and international scientific research personnel is seeking to solve the method for webbing static always.Through a large amount of research work, the following three kinds of modes of basic at present employing: 1) enroll in the fabric with conductive fiber; 2) use co-blended spinning process, antistatic additive is sneaked into fibrous inside; 3) use antistatic additive fibre is carried out surface dressing, take place crosslinked and set, or adhere to fabric face, reduce sheet resistance, reduce static focus, thereby reach antistatic purpose by resin carrier by heat treatment.
Wool is as a kind of natural fabric, because it is soft, quality is strong, and has good curling elasticity and warmth retention property, and gloss is soft naturally, is the textile raw material than higher gears always, is subjected to liking of consumers in general deeply.But in wearing process, be easy to generate static, especially tangible electric-shock feeling arranged especially, and a large amount of impurity such as dust of these Electrostatic Absorption, had a strong impact on the taking of wool in the winter of drying.On the antistatic processing problems of wool fabric, because of wool fibre is a natural fabric, so co-blended spinning need not consider, can't realize; And conductive fiber is enrolled in the fabric, complex process not only, and seriously change the original looks of wool, also inadvisable; Therefore from the actual production possibility, the third method in the said method is adopted in the antistatic processing of wool at present substantially, promptly fabric face is carried out antistatic finish.
Antistatic finish generally is with having the antistatic additive that can improve fiber regain or wettability power fibre to be put in order, alkanol phosphate as Henkel Corp., the aminoalkyl polyglycol ether, the Chinese patent publication number is a disclosed alkyl quaternary ammonium salts among the CN 1099823A, polyacrylamide, the Chinese patent publication number is a disclosed castor oil polyoxyethylene ether among the CN 1160788A, fatty alcohol-polyoxyethylene ether, lauric acid acyl diethanolamine, polyoxyethylene derivs such as stearic acid polyoxyethylene ether, the water-absorbing resins of bright one-tenth chemical industrial company etc., the purpose of these surfactants or water-absorbing resins is to improve the moisture content of fiber surface, because, when containing more water on the fiber, electric charge can be overflowed fast by moisture, promptly in the moment that two frictional interfaces separate, the quick loss of electric charge.But during this hydrophilic compounds is soluble in water again, so fastness to washing is poor.Also just like Japan Patent JP8325478 and Chinese patent publication number be disclosed stibium doping stannic oxide among the CN 1350089A, as the inoganic solids antistatic additive such as carbon black, graphite or metal dust of Poland Patent PL178064 report, but this solid antistatic additive need use just with adhesive and can be attached on the fiber, therefore operation is numerous and diverse, and its antistatic effect depends on situations such as performance such as the adhesiveness, crock fastness of adhesive and crudy to a great extent.
Summary of the invention
One of purpose of the present invention is to overcome the defective that present wool fabric is easy to generate static, provides a kind of fiber surface to have the antistatic wool fabric of nanostructured.
A further object of the present invention provides and does not a kind ofly make any chemical reagent prepare the method that fiber surface has the antistatic wool fabric of nanostructured, this method is to construct the nanoscale concaveconvex structure by this dry process technology of low temperature plasma at wool surface, and wool surface generation hydrophilic radical is realized.
The present invention is by carrying out physics and chemical modification with this dry process technology of low temperature plasma to wool surface, at first at wool surface structure nanoscale concaveconvex structure, increase the specific area of wool fibre greatly, cohesive force between the wool fibre is improved, reduce the friction between the fiber, produce hydrophilic radical at wool surface simultaneously, make electric charge pass through moisture and overflow fast, thereby reach anlistatig purpose.
When utilizing the Low Temperature Plasma Treating fabric, various active particle such as the ion that contains in the low temperature plasma, excited state molecule, free radical and fiber surface carry out various interactions.This is handled and can produce corrosion function to fiber surface, and its reason has two kinds substantially: a kind of is the sputter erosion of the particle hits fiber surfaces such as electronics, ion in the plasma.Another kind is that chemism kind in the plasma is to the chemical erosion of fiber surface.Be exactly that these two kinds of corrosion functions make wool surface produce the nanoscale concaveconvex structure.Low Temperature Plasma Treating can make fiber surface layer produce a large amount of free radicals effectively simultaneously, and this free radical just converts hydrophilic radicals such as carboxyl, amino, hydroxyl to after touching air.
Fiber surface of the present invention has the antistatic wool fabric of nanostructured, is meant that the fiber surface that constitutes wool fabric has the structure of nanoscale concaveconvex shape, and the shape of its nanoscale concaveconvex structure has varied, the diameter of its recess or wide be 30～200nm.
The preparation method that fiber surface of the present invention has the antistatic wool fabric of nanostructured is, wool fabric is put into the Low Temperature Plasma Treating chamber, then the pressure in the process chamber is evacuated to and is less than or equal to 10Pa, the pressure that feeds in the non-polymerization gas regulation process chamber is 10～170Pa, preferred 26～130Pa, more preferably 26～85Pa; Low Temperature Plasma Treating is carried out in discharge then; Power is 10～300W, preferred 30～200W, more preferably 50～100W, processing time 1～60min, preferred 1.5～30min, more preferably 5～20min.
When Low Temperature Plasma Treating, if vacuum is low excessively, the mean free path of electronics is little, electronics energy from the external electric field acquisition in a collision cycle is little, thereby energy is high enough to excite the number of electrons of ionized gas molecule or atom few, the number of active particle is few in the plasma atmosphere, and energy is low, acts on the weak effect behind the wool surface; If vacuum is too high, gas is thin, and number of particles itself is just few, the number of particles that can be used for exciting, ionization generates active particle just still less, thereby the number of particles that acts on the wool surface is few, and two opposite factors make when vacuum is moderate, just can obtain best treatment effect.During Low Temperature Plasma Treating, if discharge power is too little, the then required processing time is long; If power is too big, and discharge instability reacts bad control.If processing time does not have effect too short; If long, bigger to fibre damage.
The gas of described feeding is non-polymerization gas or their any mists such as air, oxygen, nitrogen, carbon dioxide, argon gas, helium, ammonia.But preferably use air from the simplification and the cost consideration of operation.
The present invention adopts low temperature plasma that wool fabric is handled, at wool surface structure nanoscale concaveconvex structure, increase the specific area of wool fibre, cohesive force between the wool fibre is improved, reduce the friction between the fiber, while makes electric charge pass through moisture and overflows fast at wool surface generation hydrophilic radical, thereby obtains the wool fabric of antistatic property excellence.This technology is not used any antistatic additive, complete antistatic finish technology different from the past, and technology is simple, non-wastewater discharge, non-environmental-pollution, energy savings, effect is lasting and excellent, has remarkable economic efficiency and social benefit.
