Abstract: A flame-retardant magnetic composite resin composition is provided which comprises 10 to 50% by weight of a binder resin mixture containing 100 parts by weight of a polyamide resin and suitable amounts of the following components (A) to (G), and 50 to 90% by weight of a magnetic powder of which the surface is treated with a surface-modifying agent.______________________________________ (A) Phenol 0.01 to 2.0 parts by weight (B) Thiophosphate compound 0.001 to 0.5 parts by weight (C) Copper compound 0.0001 to 0.05 parts by (based on copper weight content) (D) Bromine or nitrogen 10 to 30 parts by weight containing flame- retardant agent (E) Flame-retardant 2.5 to 7.5 parts by weight synergist ______________________________________The composition of the present invention, which is endowed with a high heat resistance and significantly improved physical properties and processability, may also include 0.001 to 0.5 parts by weight of an alkali metal halogenide compound and 0.2 to 1.0 parts by weight of a lubricant.

Abstract: The present invention relates to a melt processable wholly aromatic polyester which includes the recurring moieties (I), (II), (III), and (IV), wherein the recurring moiety (IV) is present in an amount of 5 to 35 mole % based on the total amount of the moieties and can be subjected to melt process at a temperature below 350.degree.

Abstract: A method for manufacturing loom beams for woven fabrics comprising the step of preparing a dividable warper beam which has the form of dividing a conventional single large warper beam into a plurality of divisional warper beams each having a uniform or non-uniform width and the step of using properly these beams together with the single large warper beams to utilize the maximum content of creel at a sizing or warping machine so that the generation of residual yarns can be minimized.
