摘要:
A rubber-cord composite body used for cord reinforcing rubber articles is produced by embedding fiber cords treated with an epoxy compound and further with a particular resorcin-formaldehyde-rubber latex adhesive into a particular rubber composition containing 0.5.about.10 parts by weight of each of a bismaleimide compound and sulfur.
摘要:
Spin finish compositions having as base oil polyether compounds which are .omega.-methoxy-poly (oxyethylene/oxypropylene) ether derivatives of a specified type and containing 0.05 to 10 weight % of polyalkylene oxide modified polysiloxane of another specified type are particularly desirable for application to polyester and polyamide yarns for ultra-high speed texturing because they have the characteristics of preventing fuzz on the yarns, thermally degraded substances and tacky white powder as well as reducing tackiness of such white powder.
