Production of chemical fiber spinning pure or blended, the factories do not have air conditioning, open fan humidification spray when the temperature and humidity workshop is not enough, these are a direct result of difficult to control the temperature and humidity is good, it is prone to winding roller, for anti-winding, manufacturers will choose the glue It was coated surface of the roller type coating process, but these coatings process prone wounds cot phenomenon and shorten its life. To solve this problem, you should choose a new coating process, such as: penetration coatings. Today, a simple set-permeable coating used on the roller surface effect. Through Coated Paint Roller Paint Roller and infiltration test comparison, the spin and the machine forward, Coated Paint Roller and colorless permeable coating process Cots doing the same station, same ingot test comparison, Coated Paint CV value 2.47%, while the infiltration of only 2.14% -2.52%, the obvious value to reduce CV; the same application on front woven roving, coating type coating CV is 4.16%, penetration type is 3.65% -4.06%; the same is applied on spinning Cots CV penetration of the coating is significantly lower than the coating type coating process rollers. In the course of a test than the number found decapitated around the flower number permeable coating of rubber rollers are less than Coated paints cot and cot phenomenon cuts were to occur in permeable coating of rubber rollers surface, effectively extending the service life. Permeable coating relatively cheap, since the coating is thin so fast drying speed, drying time is generally only takes 24 hours, is half the composite coating; and ease of operation, the operator's requirements are not high. Application of lower hardness rubber roller, to achieve a light, smooth, dry, cool effects, which could reduce the CV value, and neps, thick section, details are significantly reduced, thereby improving the quality of products; the lower hardness, elasticity increases, also strengthened the grip and controls on fibers; enhance the anti-interference performance, significant reduction in the phenomenon cuts cot, Tenders reduce labor intensity, increase the number of re-grinding, improve life, And the coating long life cycle, not falling, colorless coatings can generally be used four months or so, is a composite coating double
