摘要： PURPOSE:To improve the color deepening effect, by adding a specific phosphorus compound containing a metal and an alkali metallic compound to any stage till the completion of the synthesis of a polyester, melt spinning the polyester, treating the extruded fibers with an alkali, and coating the treated fibers with a polymer having a low refractive index. CONSTITUTION:A phosphorus compound, containing a metal, and expressed by the formula [R and R are H or monofunctional organic group; M is an alkali (earth) metal; m is 1 when M is alkali metal, and (1/2) when M is alkaline earth metal] and an alkaline earth metallic compound without the previous reaction of both are added to any stage till the completion of the synthesis of a polyester. The molar amount of the alkaline earth metallic compound is 0.5- 1.2 of that of the phosphorus compound containing the metal. The resultant polyester is melt spun to give fibers, which are then treated with an aqueous solution of the alkali compound to elute 2wt% or more polyester fibers. The treated fibers are dyed and then coated with a polymer having a lower refractive index than that of the fibers.

摘要： PURPOSE:Isophthalic acid containing a sulfonate salt, a specific phosphorus compound and a lithium compound are added, then the polymerization reaction between terephthalic acid or its derivative and glycol is conducted, the polymer is made into fibers, and a part of the fibers is leached out with an alkali to produce synthetic fiber having special fine pores and good dyeing properties. CONSTITUTION:When terephthalic acid or its ester-forming derivative and glycol are made to react into polyester and the polymer is made into synthetic fibers, (A) 0.5-10mol%, based on the total acid components, of isophthalic acid containing alkali metal sulfonate groups, (B) 0.3-3mol%, based on the total acid components, of a phosphorus compound of the formula (R , R are H, organic group; X is H, organic group, metal; m is 0, 1), (C) a lithium compound are added so that the total equivalents of the metals in components B and C becomes 2.0-3.2 times the molar quantity of component B. Then, the resultant fibers are treated with aqueous alkali to cause more than 2wt% leaching to give the objective fibers.

摘要： PURPOSE:The titled structure in which the number and size of fine pores on the polyester fiber are set in a certain range and the polyester fiber is coated with a polymer of low refractive index after dyed, thus showing colors of increased deepness and brightness, improved resistance to washing and reducing discoloration caused by friction. CONSTITUTION:The polyester fiber has fine pores which are oriented in the fiber axis direction and, at least, a part of the fine pores connect with one another inside the outer layer so that the pores distribute on the lines connecting all the points on the outer periphery with the center of the fiber cross section and the distance from the outer periphery is more than 5mum. The pore size is 0.1-3mum at the maximum in the frequency distribution. After dyed, the pored polyester fiber is coated with a pollmer of lower refractive index thab that of the polyester fiber.
