초록

A study has been made to determine if the hardness of treating and washing solution in the alkali treatment of polyester fabric affects its weight loss and ethylene glycol produced during the finishing affects the fabric's weight loss and breaking strength. The results are as follows: As the hardness of treating solution increases, the weight loss of polyester fabric decreases remarkably and insoluble precipitate sticks on its surface. When hard water is used as washing solution or weak acid used in neutralizing the fabric after alkali treatment, white powder sticks on the surface of the fabric. The weight loss of polyester fabric increases more when the fabric is treated in sodium hydroxide solution containing ethylene glycol than in the solution without ethylene glycol. The breaking strength decreases as weight loss increases, but it is almost constant at the same weight loss when the fabric is treated in the sodium hydroxide solution with or without ethylene glycol.
