At that time, a plastic plastic cup (capacity 200 mL) was used as a mixing container, and a magnetic stirrer was used as a mixing method. First, the component (e), the component (g) and water corresponding to 10% by mass of the whole composition were weighed and mixed in a container, and then the component (c) heated above the melting point was added and further mixed. Next, a predetermined amount was added while mixing the component (a) at a rate of about 2 g / min, and mixed for about 30 minutes after completion of the addition. The remainder of the blended water was added to this and mixed, and component (d) was added. While continuing mixing, the pH was adjusted to a predetermined value with the component (f), and the component (b) was added to obtain each composition. About the obtained composition, the yellowing suppression effect and texture were evaluated by the following method. The results are shown in Table 1.

<Evaluation method of yellowing suppression effect>
15 g of each treating agent composition blended by the above method is put in a glass screw tube (No. 6, 30 mm × 65 mm) having a capacity of 30 mL and sealed under atmospheric pressure (two each). This was stored in a thermostatic bath at 5 ° C. and 50 ° C. with the stoppers facing upwards and stored for 20 days, and then the cret value (420 nm absorbance × 1000) was measured with an absorptiometer. According to the following formula, the difference of the cret value between the product stored at 5 ° C. and the product stored at 50 ° C. was determined, and the Δ cret value was calculated.

Δ kret value = (Kret value of product stored at 50 ° C.) − (Cret value of product stored at 5 ° C.)
<Texture evaluation method>
(1) Pretreatment of textile product for evaluation and treatment with treatment composition New cut-and-sew (9 to 5, made by Chikuma Co., Ltd., beige, cotton / polyester = 50/50%) and new shirt (form stability) Prepare one processed shirt (SSP), Flex Japan's BLUE RIVER, white, 100% cotton), 0.9kg underwear (100% cotton) as a weight adjustment fabric, white shirt (white, cotton / polyester = 60/40%) 0.6 kg is added, and a total of 1.8 kg of clothing is repeatedly washed 10 times in a two-tank washing machine (Toshiba Galaxy VH-360S1) using a commercially available weak alkaline detergent (Kao Corp. Attack) (Detergent concentration: 0.0667 mass%, use of tap water (20 ° C.) 36 L, washing 10 minutes-dehydration 3 minutes-rinse 8 minutes (rinsing with running water, amount of water 15 L / min.)) At the time when 5 minutes have passed since the rinsing of the last treatment time (the 10th time) has started, running water was stopped, and after draining, dewatering was performed for 3 minutes. Next, 36 L of tap water (20 ° C.) was injected, 23.33 g of each treatment agent composition was added, and the mixture was stirred for 3 minutes. After the stirring was stopped, it was dehydrated for 3 minutes, and a cut-and-sew and a shape-stabilized shirt were taken out as evaluation clothes, each hung on a hanger in the shade, and hung and dried for 12 hours.

(2) Texture evaluation The texture (smoothness) was evaluated for the fiber products that had been hung and dried by the above method for 12 hours and left in a constant temperature and humidity room at 25 ° C.-65 RH for 24 hours. went.

The texture (smoothness) was evaluated for both the cut-and-sew shirt and the shape-stabilized shirt by pre-treatment, using only tap water without using a treatment agent, and then adjusting the humidity in a constant temperature and humidity chamber of 25 ° C.-65 RH. The textile product was used as a control product, and each panel was prepared by 5 panelists. The average score is greater than 1.0 and less than or equal to 2.0, ◎, greater than 0 and less than or equal to 1.0, ○, 0, Δ, −1.0 to less than 0 ×, −2.0 to less than −1.0 Judged as xx.
Since the tendency of the cut-and-sew shirt was the same, Table 1 shows the results for the shape-stabilized shirt.
・ Smoothness Contrast product is smoother: -2 points Contrast product is slightly smoother: -1 point Equivalent to control product: 0 points Slightly smoother than control product: +1 point Smoother than control product: +2 points

Example 2
A fiber product treating agent composition having the composition shown in Table 2 was prepared in the same manner as in Example 1 except that each component shown in Table 2 was used. About the obtained processing agent composition, the yellowing suppression effect and texture were evaluated similarly to Example 1. The results are shown in Table 2.
