Embodiment 1～2

[0070] Use polyethylene terephthalate fibers of 84 decitex and 72 filaments and polyethylene terephthalate fibers of 84 decitex and 36 filaments to weave braids, which are conventionally The method is scouring, drying, intermediate setting. Next, dyeing, washing with hot water, and drying were performed by a conventional method using a flow dyeing machine. This was dipped in the following hydroxy acid aqueous solution, squeezed with a squeeze machine so that the squeeze ratio was 91%, dried at 130°C, and set at 170°C for 1 minute.

Embodiment 1

[0071] Example 1; Citric acid (anhydrous) (manufactured by Nakalai Tesuk Co., Ltd., Nakalai Specification Grade 1)

[0072] 18g / L

Embodiment 2

[0073] Example 2; Citric acid (anhydrous) (manufactured by Nakalai Tesuk Co., Ltd., Nakalai Specification Grade 1)

Abstract

Disclosed is a polyester-based fiber structure, which exerts excellent washing durability and deodorizing properties and which is characterized by being attached with a substance comprising a hydroxy acid derivative and / or hydroxy acid.

Description

technical field [0001] The present invention relates to a deodorizing polyester fiber structure excellent in washing durability. Background technique [0002] In recent years, with the diversification of life, the awareness of health and hygiene has increased, and products with deodorizing and antibacterial functions have been put into practical use in various fields of clothing, food and housing. In particular, from the viewpoint of health promotion, various indoor and outdoor sports are actively performed, and there is an increasing demand for fiber products that absorb a large amount of sweat generated during exercise and have a large deodorizing capacity. In addition, not only deodorization but also multiple functions such as water absorption and waterproofing are required in nursing care and medical fields associated with aging, and there are high expectations for products with high deodorization functions. [0003] As methods for imparting deodorant properties, a meth...
