Its preparing process includes such steps as providing a fabric as substrate, delivering it while coating adhesive, making the charred bamboo fibers to be negatively charged, flocking them onto said adhesive layer by a high-voltage electric field, baking, water washing, printing and finishing for flame retarding.
Description
Technical field
The present invention relates to fabric and processing method thereof, relate in particular to a kind of bamboo carbon fiber electrostatic flocking and production method thereof of energy pure air.
Background technology
Along with The development in society and economy, on the one hand people living standard improve constantly, people's living environment wrecks on the other hand.As, developing of automobile industry has changed people's life style, accelerated socio-economic development, but the investigation of 2 first quarter moons detected and found when Country Environmental Analysis Test Center once to 1000 automobiles of producing between in January, 2003-March was, there is car to have in-vehicle air pollution up to 97%, 37% house decoration than same period investigation exists indoor pollution high, with reference to the IAQ (indoor air quality) standard, all there is the problem of interior air formaldehyde of car or benzene content overproof in these automobiles, and most of vehicle formaldehyde exceeds standard all more than five or six times.Justice as, the development of real estate has improved people's living environment, but interior decoration causes living environment secondary pollution problem again.For fresh air, often use chemicals sterilization, perfumes to hide, but the new often polluter of these chemical agents, in addition, long-term people produce baryo,dmia probably in such abnormal smells from the patient, do not know to be injured in the feel.Present a lot of perfume is not natural extract, but synthetic, itself just has certain pollution, and in fact air quality is without any improvement.Activated carbon adsorbent is the method for another kind of fresh air.
Summary of the invention:
The object of the invention is to provide a kind of bamboo carbon fiber electrostatic flocking and production method thereof that can pure air, and the preparation electrostatic flocking because the bamboo charcoal powder in the bamboo carbon fiber has the activated adoption effect, makes this fabric have the pure air function.
The technical solution adopted for the present invention to solve the technical problems is as follows:
One, a kind of bamboo carbon fiber electrostatic flocking of energy pure air
Bottom cloth layer one side or two last bonding bamboo carbon fiber tapetums.
Described bamboo carbon fibre is that viscose rayon adds the bamboo carbon powder, modified poly ester adds the bamboo carbon powder or chinlon adds the bamboo carbon powder.
Described bamboo carbon fibre density range is: 1.11dtex～11.11dtex, bamboo carbon fiber villus length scope is: 0.1～20mm.
Described base fabric is woven fabric, knitted fabric, non-weaving cloth, plastic sheeting or leather.
Two, a kind of production method of bamboo carbon fiber electrostatic flocking of energy pure air
With the base fabric on the fabric intake roller through scraper pasting adhesive coating on base fabric, and the electronegative container of bamboo carbon fiber fine hair is housed in above being delivered to, carry out flocking between the high voltage electric field generator of zero potential down, bamboo carbon fiber fine hair is implanted density and is controlled by selecting to start 1 to 4 electronegative container arranged side by side, after oven for drying, be wound to the output roller, flocking is after washing, flame-proof treatment, perhaps flocking after washing, stamp, flame-proof treatment form.
Described high voltage electric field generator rated voltage 50kV, output current 5MA, high voltage electric field anode-cathode distance 12cm, flocking web area 4m

The present invention compares the beneficial effect that has with background technology:
(1), the bamboo charcoal powder in the bamboo carbon fiber has adsorption, makes the bamboo carbon fiber electrostatic flocking have the pure air function.
(2), the villus fiber bundle surface area of bamboo carbon fiber electrostatic flocking fabric increases, the air that is coated also increases thereupon, can make that bamboo charcoal powder in the bamboo carbon fiber is a large amount of to absorb airborne abnormal flavour.
(3), the pure air function is attached in the environmental decoration product, need not to increase isolated plant.
(4), bamboo carbon fiber electrostatic flocking fabric surface touch softness.

Fig. 2 is a bamboo carbon fiber structural representation of the present invention;
Fig. 3 is the technology and the principle of bamboo carbon fiber electrostatic spinning of the present invention;
Fig. 4 is the present invention's section in kind.
Among the figure: 1. bamboo carbon fiber tapetum, 2. adhesive layer, 3. base fabric, 4. viscose rayon or modified poly ester or chinlon, 5. bamboo carbon powder, 6. bamboo carbon fiber fine hair, 7. electronegative container, 8. baking oven, 9. zero potential, 10. high voltage electric field, 11. adhesive.
The specific embodiment
As shown in Figure 1, the present invention's bonding bamboo carbon fiber tapetum 1 on the adhesive layer 2 of base fabric 3 one sides.
As shown in Figure 2, described bamboo carbon fibre is that viscose rayon 4 adds bamboo carbon powder 5, modified poly ester 4 adds the bamboo carbon powder or chinlon 4 adds bamboo carbon powder 5.
Described bamboo carbon fibre density range is: 1.11dtex～11.11dtex, bamboo carbon fiber villus length scope is: 0.1～20mm.
Described base fabric 3 is woven fabric, knitted fabric, non-weaving cloth, plastic sheeting or leather.
Electrostatic spinning is one and relates to multi-disciplinary complex arts such as static, machinery, chemical industry.Bamboo carbon fiber fine hair is prepared, and comprises fine hair cutting, electric tinction, screening, flocking, back arrangement, is common process.
The electricity tinction is the crucial link of bamboo carbon fiber electrostatic spinning.Dye bath ratio is 1: 30, with the heating of the solution that regulates and constantly stir, is 45 ℃ up to temperature, add electricity inorganic agent, continue heated and stirred, add dyestuff behind the 20min, when temperature was elevated to 90～95 ℃, 60min was kept in insulation; Reduce temperature to 30～40 ℃, and with 30～40 ℃ clear water washing 3～4 times, oven dry is screened.Fine hair moisture 6.5%; Fine hair is than resistance 90nrm; Ascending to heaven property: 8s/2g; Dispersibility is better.
As shown in Figure 3, with the base fabric on the fabric intake roller through scraper pasting adhesive coating 11 on base fabric, and the electronegative container 7 of bamboo carbon fiber fine hair is housed in above being delivered to, carry out flocking for 10 in the high voltage electric field generator of zero potential 9 down, bamboo carbon fiber fine hair is implanted density and is controlled (the figure China National Instruments Import ﹠ Export Corporation is represented 1 electronegative container) by selecting to start 1 to 4 electronegative container 7 arranged side by side, after baking oven 8 oven dry, be wound to the output roller, flocking is after washing, flame-proof treatment, perhaps flocking after washing, stamp, flame-proof treatment form.
Be the technology and the principle of bamboo carbon fiber electrostatic spinning as Fig. 3: electrostatic spinning is utilize the electric charge same sex to repel each other the physical characteristic that there is a natural attraction between the sexes, bamboo carbon fiber fine hair 6 is placed in the electronegative container 7, make negative charge on the bamboo carbon fiber fine hair band, the base fabric 3 that needs flocking is placed on the high voltage electric field 10 that forms between zero potential 9 and the electronegative container, bamboo carbon fiber fine hair 6 in container be negative charge, be subjected to different current potential by the attraction of flocking base fabric 3, become vertical configuration to quicken to fly on base fabric 3 surfaces that need flocking, owing to scribbled adhesive 11 by the flocking base fabric, bamboo carbon fiber fine hair 6 is just by vertical sticking being implanted on the base fabric 3 that needs flocking.
The implantation of fine hair can be adopted from top to bottom (descent method), (rise method) and side fly flocking modes such as formula from bottom to top.
Described high voltage electric field generator rated voltage 50kV, output current 5MA, high voltage electric field anode-cathode distance 12cm, flocking web area 4m
