レフタレートが好ましく用いられる。The polyester fiber product of the present invention is a product containing a modified polyester component and an unmodified polyester component in the same fiber or fiber product, and the modified polyester component is treated with the same alkaline bath as the unmodified polyester component. It is desirable that alkali hydrolysis is performed at least three times at a weight loss rate, and a polyester component modified by copolymerizing polyethylene terephthalate with an aromatic dicarboxylic acid such as isophthalic acid or an aliphatic dicarboxylic acid such as adipic acid is preferably used. However, a modified polyester component obtained by copolymerizing a sulfonic acid metal base-containing dicarboxylic acid or a diol other than ethylene glycol such as neopentyl glycol and butylene glycol is also used. The amount of the copolymerization component for modification is 1 to 15 mol%
Those copolymerized are used. The unmodified polyester component does not introduce an acid group or a salt thereof into the side chain and has a copolymer component of 0.5 mol% or less, and polyethylene terephthalate is preferably used.

〜20重量％付着させることが望ましい。In the present invention, triethanolamine previously attached to the polyester fiber product is a compound represented by the chemical formula N (CH 2 CH 2 OH) 3 , and may be used alone. It is desirable that the adhesive be used in combination with a sizing agent, a surfactant for penetration, or the like. It is also possible to simultaneously attach a disperse dye, a dispersant, a pH adjuster, and the like for coloring the unmodified polyester component to be left.
The method of adhesion is generally a method of dissolving in water, adding a water-soluble sizing agent and adhering to a predetermined pattern as a printing paste, but a method of adhering an aqueous solution or directly triethanolamine by dipping, spraying or the like may be used. Adhesion amount is 3 for textile products
It is desirable to adhere to about 20% by weight.

At this time, coloring of the disperse dye used in combination can be performed at the same time. If the temperature is lower than 140 ° C., it is difficult to remove the modified polyester component. If the temperature exceeds 200 ° C., the unmodified polyester component is undesirably deteriorated in strength and discolored. Further, it is difficult to remove the modified polyester component by dry heat treatment or high-pressure saturated steam treatment.

Using a yarn obtained by twisting 0d / 24f (120T / M), a knitted fabric of 24G was knitted. Next, the following printing paste was adhered to the knitted product in the form of a handle, dried at 130 ° C. for 2 minutes, and then heat-treated with superheated steam at 180 ° C. for 10 minutes. Thereafter, washing with water was carried out, and treatment was performed for 30 minutes in a 10 g / l boiling aqueous solution of caustic soda. After neutralization according to a conventional method, drying was performed. The adhesion rate of the printing paste was 120% (based on the knitted fabric) on average. As shown in the following table, according to the present invention, an exfoliated product having a blue polyethylene terephthalate fiber portion without discoloration in the handle portion was obtained. The burst strength of the handle of this knitted fabric is all 4 kg / cm
The burst strength was 4 kg / cm 2 or more and hardly decreased even after a 1-week accelerated test at 70 ° C. and 90 to 100% RH corresponding to a three-year change of the polyester fiber over time. As a comparison, poor extraction or good extraction but bursting strength of 2 kg / cm 2 or less and 2 kg / cm 2 after accelerated test
