• a temperature of the heating atmosphere is preferably 50 to 120°C, more preferably 50 to 110°C, and even more preferably 50 to 100°C.
• a heat treating time which largely depends on a temperature of the heating atmosphere or a function of a heating dryer or a heating washer-dryer or the like, is about 5 to 400 minutes.
• the step A and the step B can be simultaneously conducted under a high temperature atmosphere by placing a carrier having the textile treatment composition containing the components (a) and (b1) together with a textile product under a high temperature atmosphere. Further, the step A and the step B can be simultaneously can be conducted or by contacting the carrier having the textile treatment composition with a textile product under ambient atmosphere and heating to change the atmosphere to a high temperature atmosphere. In latter case, the carrier having the textile treatment composition of the present invention and a textile product are preferably stirred so as to be contacted each other at high frequency.
• a textile product contacted with the carrier having the textile treatment composition of the present invention preferably contains water, because the component (b1) is adsorbed on the textile product via water as a medium.
• Water contained in the textile product is preferably 30 to 300% by mass, more preferably 30 to 200% by mass, even more preferably 30 to 150% by mass, and even more preferably 30 to 100% by mass of the textile product.
• a required amount of 95% by mass of ion-exchanged water was heated to 62°C in a water bath. With stirring at 500 rpm, the component (d) in a molten state was added. Then, to this were added the component (c), (g) and (h), which were previously mixed and heated to melt at 70°C. To this was added a necessary amount of 35% aqueous hydrochloric acid and/or 48% aqueous sodium hydroxide to adjust pH to a predetermined value and stirred for 5 minutes.
• Textile treatment compositions thus obtained were used to treat a textile product according to the following method, and measured for an adsorption rate of fragrance. The results are shown in Table 2.
• a textile treatment composition was dissolved in 5 L of tap water so as to be 10 g of the composition per 1.0 kg of fabric (preparation of a treatment bath).
• Two cotton towels pretreated as described above were soaked therein for 5 minutes, and stirred for treatment.
• the soaked towels were transferred to a domestic two-tub washing machine, and dewatered for 1 minute.
• An adsorption rate of fragrance material is determined from an amount of fragrance in a treatment bath before treatment (x) and an amount after treatment (y) by deducting (y) from (x) to meet an absorbed amount on towels [(x) - (y)] and calculating a rate (percent) of the absorbed amount to the amount before treatment (x), that is, [(x)-(y)]/(x) ⁇ 100.
• the results are shown in Table 2. In measuring an amount of fragrance in a treatment bath before and after treatment, the following liquid chromatography unit was used.
• Textile treatment compositions shown in Tables 4 to 6 were prepared using fragrances 1 to 3 shown in Table 3.
• the resultant textile treatment compositions were used to subject cotton towels pretreated similarly as in Example 1 to the same softening treatment. Treated towels were dried for 24 hours at 25°C and 40%RH, and subjected to a comparative sensory evaluation for long lasting odor. A result of the sensory evaluation was shown by the panelists' number, in 10 panelists, judging that an aroma perfumes stronger than that in a towel treated with a composition without the component (a) (blank 1) .
• Table 4 shows results of similar evaluation for aroma strength, including a composition containing phenylethyl alcohol (blank 2) that is a fragrance used for preparing the component (a-1) instead of the component (a).
• Textile treatment compositions 10 and 11 were similarly prepared as in Examples 1 to 3 and Comparative Examples 1 to 4, using components as shown in Table 7 at ratios of Table 7 such that the final textile treatment composition was 300 g.
• the resultant textile treatment compositions were used to treat a textile product according to the treatment described above.
• the treated textile product was dried and subjected to a sensory evaluation for long lasting odor as described below.
• a cotton towel treated as described above was heat-treated for 2 hours in a National washer-dryer NH-D502 (temperature in a dryer: 68°C), and hanged in a thermostatic chamber and left for 22 hours at 20°C/60%RH.
• treatment method 2 A cotton towel treated as described above was hanged in a thermostatic chamber and left for 24 hours at 20°C/60%RH without using a washer-dryer.
• Cotton towels heat-treated by the method 1 including a treatment with a washer-dryer
• treated by the method 2 naturally drying without a washer-dryer
• a result of the sensory evaluation was shown by the number of panelists judging that an aroma perfumes stronger. The results are shown in Table 7.
• Textile treatment compositions 12 to 15 were prepared according to the following process of preparation, using components as shown in Table 8 at ratios shown in Table 8 such that the final textile treatment composition was 300 g.
• the resultant textile treatment composition were put in glass bottles and stored for one month at 40°C in a thermostatic chamber.
• the stored compositions were used to treat a textile product according to the following method of treatment, and measured for adsorption rate of the component (b1-3) on the textile product according to the method described above. The results are shown in Table 8.
• a required amount of 95% by mass of ion-exchanged water was heated to 62°C with a water bath. With stirring at 500 rpm, to this was added the component (d) in a molten state. Then, to this were added the component (c) and a mixture of the components (g) and (h), which were previously mixed and heated to melt at 70°C. To this was added a necessary amount of 35% aqueous hydrochloric acid and/or 48% aqueous sodium hydroxide to adjust pH to a predetermined value, and stirred for 5 minutes.
• a textile treatment composition was dissolved in 5 L of tap water so as to be 10 g of the composition per 1.0 kg of fabric (preparation of a treatment bath). Two cotton stockinets pretreated as described above were soaked therein for 5 minutes, and treated.
