The deodorant fabrics of Examples 1 to 10 and Comparative Examples 1 to 8 were evaluated by the following methods for deodorant performance, durability of deodorant performance, texture and dot processability.

(1) Deodorant performance After putting the deodorant fabrics of Examples 1 to 10 and Comparative Examples 1 to 8 cut into 10 cm × 10 cm into a 5 L tedler bag and enclosing 3 L of air, the initial concentration A1 is increased. Ammonia gas was injected so as to be 200 ppm. After 2 hours, the residual ammonia gas concentration B1 was measured using a gas detector tube (manufactured by Gastec), and the deodorant amount was calculated by the formula (15). When the deodorizing amount was 100 ppm or more, it was evaluated as "good deodorizing performance". When the dot processing was poor, the deodorant performance was not evaluated.
Deodorant amount (ppm) = B1-A1 ... (15)

(2) Sustainability of deodorant performance For the deodorant fabrics of Examples 1 to 10 and Comparative Examples 1 to 8, "SEK mark textile product washing method (edited by the Textile Evaluation Technology Council)" The washing was carried out by the method according to the "washing method of the product specified 50 times by the high temperature accelerated washing method" described in the above. Then, the deodorant performance was evaluated by the same method as in (1) above. If the deodorant amount is less than 100 ppm or 1/2 or more, the deodorant performance is not sustainable, and if the deodorant amount is not 100 ppm or more or 1/2 or less, the deodorant is deodorized. It was evaluated that the performance was sustainable. When the dot processing of the resin portion 20 was poor, the sustainability of the deodorant performance was not evaluated.

(3) Texture Based on the feeling of holding the deodorant fabrics of Examples 1 to 10 and Comparative Examples 1 to 8 with bare hands, the fabrics were evaluated to be particularly soft, soft, normal or hard. When the dot processing was poor, the texture was not evaluated.

(4) Dot processability When a deodorant paste was screen-printed on a polyester woven fabric in a dot pattern, it was evaluated whether or not dot processing could be performed without any problem.
