Title:
強化用繊維束の接続方法、長繊維強化熱可塑性樹脂ペレットの製造方法及び巻回体
Document Type and Number:
Japanese Patent JP5286227
Kind Code:
B2
Abstract:
A method for connecting a tail end portion of a reinforcing fiber bundle of a preceding wound body to a front end portion of a reinforcing fiber bundle unwound from a new wound body by blowing pressurized air to both of the ends to unravel and entwine both of the reinforcing fiber bundles, wherein the method includes a preparation step for adjusting the amount of a sizing agent contained in the front end of the reinforcing fiber bundle unwound from the new wound body and the tail end of the preceding wound body to not less than 0wt% and not more than 4wt%, and the reinforcing fiber bundles are connected after the preparation step. It is thus possible for the reinforcing fiber bundle at the time of producing a long fiber reinforced thermoplastic resin pellet that is a material for the pellet to have a required connection strength, and to avoid the occurrence of interruption due to breakage, and accordingly allowing improvement in the production efficiency of the long fiber reinforced thermoplastic resin pellet, etc.
