The product is applicable to the adjacent model ring spun yarn frames FA502,FA503,FA507,etc.Its main body is made of the compound material of carbon fibre with Nylon 66 by means of plastic injection , so being characteristics of hardness and solidity ,furthermore, a stability is also inserted during the injection moulding, thus the rusting with the guide plate has been thoroughly resolved. The plastic injection moulding is completed in one move. Good consistency of the yarn guide angle; It became more easier to guide the yarns than with the iron-made yarn guide plate thanks to its way of fixture. The material for the yarn guide hook is the wearing-resistant steel of special kind plus an advanced hardening treatment , so more smooth , more durable , easy to mount ans dismount , top wearing-resistence , no deformation during use, ageing-resistant and long cycling . Thus the rusting problem as an inherent case for the iron yarn guide plate has been thoroughly resolved.
