Chargeable tow, laminates using the same and processed goods therefrom

Chargeable tow which comprises synthetic fiber of thermoplastic resin, of which the fineness of single yarn is 0.5 to 100 deci-tex (dtex), in which each synthetic fiber has crimps, the total fineness is 10,000 to 300,000 dtex, and the value (D/W) obtained by dividing the total fineness (D) by the tow width (W) is in a range of 1,000 to 8,000 dtex/mm, and to which has adhered a fiber-processing agent containing components A and B (60 to 95% by weight of the component A and 5 to 40% by weight of the component B, based on the fiber-processing agent), wherein the component A is a mixture of a polyoxyethylene higher fatty acid ester of the following general formula (1) and one or more species of a sorbitan fatty acid ester of the following general formula (2) or (3);

• and the component B is a polyoxyethylene higher fatty acid ester of the following general formula (4) and/or general formula (5):
• [General Formula (1)]
• 11

• and k is an integer of 2-50,
• [General Formula (2)]
• 12
• [General Formula (3)]
• 13
• wherein R2, R3 and R4 each is a hydroxyl group or polyoxyethylene group, wherein the polymerization degree of the polyoxyethylene group (repeated unit of the polyoxyethylene group) is 2 to 55;
• and R6 is a saturated or unsaturated aliphatic hydrocarbon group of 16 to 30 carbon atoms,
• [General Formula (4)]
• 14
• wherein R6 is a saturated or unsaturated aliphatic hydrocarbon group of 16 to 30 carbon atoms;
• and m is an integer of 2 to 50, and
• [General Formula (5)]
