Method for producing ultrafine polyester fiber |
| abstract |
(57) [Summary] [Purpose] A method for producing ultrafine polyester fibers used for clothing and industry, which can be produced using a normal polyester spinning device without using a special spinneret such as composite spinning or mixed spinning. I will provide a. [Structure] A polyester having a main repeating unit of ethylene terephthalate and containing 0.1 to 10% by weight of an organic sulfonic acid metal salt represented by the following formula (1) is melt-spun, and then the obtained fiber or the fiber is obtained. After the dry heat treatment of the woven or knitted fabric made of the above at a temperature of 120 ° C. or more for 10 seconds or more, a weight reduction of 20% or more of the fiber weight is further performed with an aqueous solution of an alkaline compound, and then the fiber is mechanically treated. A method for producing an ultrafine polyester fiber, characterized in that it is divided. R-SO 3 M (1) Here, R is an alkyl group having 3 to 30 carbon atoms and 7 to 7 carbon atoms. The aryl group M of 40 is an alkali metal |
