This paper studies the electrodeposition processing ECDP fibers for electrostatic flocking fluff and flocking. Including the structure and properties of analysis ECDP fiber content, and select the appropriate electrical treatment agent and electrical process based on its performance; discussion of fluff in the electrostatic field under different charging methods and exercise flocking performance factors, and through experiments The optimum flocking process. Fibers and PET fibers of ECDP comparative analysis First, infrared spectroscopy and X-ray diffraction, and mechanical properties, moisture absorption and electrical properties of the test results showed that the crystal structure of the ECDP fiber and PET fiber is substantially similar, but ECDP fiber amorphous zone is large, the degree of crystallinity is slightly smaller than the PET fibers, so ECDP fiber breakage strength and initial modulus ratio of the PET fibers is low, and the high elongation at break in; ECDP fibers with the sulfonic acid groups of the third component more-COOH groups, hygroscopicity and better conductivity, moisture regain of 2.42% and a specific resistance of 8.47 × 10 11 Ω · cm. According fiber performance ECDP, drawn electrically with the base formulation of the treatment agent, and the test performance through experiments optimum recipe: antistatic agents SN 6% aluminum potassium sulfate 6% of sodium silicate 2% softener 6%, the dispersant IW 1% glacial acetic acid 2%, penetrants JFC1. Electro treated fluff soaring 10.0 s/2g, the dispersion was 44.2%, the specific resistance of 4.3 × 10 6 Ω · cm, villous moisture content of 8.2%, the indicators are achieve the the electrostatic flocking plush standard requirements. The Best Electro treatment process through experiments: Electro-treatment temperature of 60 ° C, a liquor ratio of 40:1, the time for 30 min fluff the best performance, flocking best. Fluff in the electrostatic field of the charge corona discharge and polarization charge two. The mode of corona discharge, to improve the voltage of the corona discharge and increase the humidity of the medium can increase the fluff particles aggregate external force, to accelerate the movement of fluff. However, when the applied voltage is excessively large, the result in the disappearance of the residual charge, villus tip discharge phenomenon occurs due to inductive charge generation or recharge, but affect the speed of its movement and orientation; the electrode charging mode, to improve the fluff in the electric field together external force, so that fluff and movement speed in the electric field, the need to improve the conductivity of the fluff can be achieved by reducing fluff specific resistance. Movement of fluff in the electrostatic field there are two types of translation and rotation. By analysis of fluff translational, fluff velocity and the charge quantity of the villi, the air resistance coefficient, and the electric field intensity. Applied electric field strength is the main factor affecting the flocking effect, the greater the intensity of the electric field, the greater the value of the electric force correspondingly greater speed villi into the binder, so the implant depth of the villi is deeper, flocking fastness higher. However, the electric field strength is too large will cause the fluff itself discharge, impact flocking effect. Additionally can improve the fluff band power and reduce the air resistance coefficient to improve the speed of movement of the villi; flocking time and electrode distance will affect the flocking effect on villus rotation. Fluff through the flocking area longer, greater the fluff interpolation Ruji Bu speed. Reduce the distance between poles help to improve the electric field strength, but for good orientation to make fluff plug Ruji Bu, plate distance can not be too small. In a pilot study of the electrostatic flocking process by changing the applied voltage, the distance between the plates and flocking time three process parameters, respectively, to discuss its impact flocking density, concluded: When flocking time and the upper and lower plates the distance between a certain time, as the applied voltage increases, the flocking density of the fabric is increased; flocking time, and the applied voltage is constant, flocking density decreases with the increase of the distance between the plates; When the applied voltage and plate certain distance, flocking density is increased with increasing flocking time, eventually stabilizing. The four-factor orthogonal experiment, the main factors of the flocking flocking density of the applied voltage, the distance between the plates and flocking time significance analysis, we can see: the distance between the plates flocking density the greatest extent, followed by flocking time, while the influence of the applied voltage is relatively small. Best flocking applied voltage of 60kV, the distance between the plates is 10cm, flocking time 14s.
