| abstract | 1324804 Treating polyester filaments FIBER INDUSTRIES Inc 20 Nov 1970 [20 Nov 1969 6 April 1970] 55240/70 Heading B5B [Also in Division D1] A process for improving the bondability to rubber of polyester filaments and tyre cords comprises treating undrawn or partially drawn polyester filaments with composition containing a polyepoxide (an epoxide containing more than one epoxide group per molecule) in the absence of a catalyst or curing agent and hot drawing the treated article. Preferred polyester filaments contain at least 95% by weight polyethylene terephthalate, although other linear homopolymeric or copolymeric polyesters may be used, and are capable of being hot drawn to a draw ratio of at least 1À2. Suitable polyepoxides (long list given) are aromatic or aliphatic glycidyl ethers or aromatic glycidyl esters having a molecular weight of less than 500 and a molecular weight per epoxide group of less than 200, ethers made from epichlorohydrin and a triol being preferred. The polyepoxide may be applied in an aqueous alkaline solution or emulsion containing a lubricant (e.g. dimethylpolysiloxane), the application and hot drawing being carried out as an integral part of a melt spinning process (Fig. 1, not shown). Prior to application of the rubber latex and after drawing the epoxide treated filaments are preferably dipped in a resorcinol-formaldehyde latex containing vinyl pyridine and having a formaldehyde to resorcinol mole ratio of between 1À2 and 2 to 1. Examples relate to the treatment of freshly spun polyethylene terephthalate filaments. |
