In order to solve these problems, a composition containing cellulase such as endoglucanase is known as a cleaning agent for removing fluff produced in textile products. By blending cellulase, fluff generated in cellulose-containing fibers (for example, cotton, hemp, rayon, or a blended fiber of these with other fibers) is cut, and deterioration of the appearance of the fiber product is suppressed.
For example, Patent Document 1 discloses the effect of cellulase (damaged cellulose by adding a water-soluble polymer obtained by polymerizing one or more monomers selected from the group consisting of vinyl pyrrolidone, vinyl alcohol, vinyl carboxylate, acrylamide and soluble acrylate. A technique for improving the fiber removal effect) is disclosed.
Patent Document 2 discloses, as an agent for removing fluff produced in a textile product, a single terephthalic acid-alkylene glycol copolymer or a specific terephthalic acid-oligoalkylene glycol copolymer, together with an endoglucanase having a cellulose binding domain. Contained cellulase preparations have been proposed.

On the other hand, if it is below the preferable upper limit value, it becomes easy to achieve a blending balance with other components. When the preferable upper limit is exceeded, the cleaning effect is enhanced, and the component (A) and the component (B) may be easily removed from the fiber.

  In addition, in the composition for treating textile products of the present invention, the use of a linear alkylbenzene sulfonate widely used in a conventionally known garment detergent as an anionic surfactant makes the component (A) modified. However, this is not preferable from the viewpoint that the activity tends to decrease.

In the present invention, “mass ratio represented by (B) component / (C) component” means the ratio of the mass of component (B) to the mass of component (C) in the composition for treating textile products. Represents.

If it is 0.45 or less, the complex is easily formed. If it is 0.20 or less, the complex is more easily formed. If it is 0.15 or less, the complex is further formed. This makes it easy to obtain a good conditioning effect and, in addition, a good fluff removal effect. On the other hand, when the mass ratio represented by (B) component / (C) component is less than 0.02, (C) component is present in the fiber, so that (A) component and (B) component are washed and removed from the fiber. There is a risk that it will be easy to be.

After stopping the reaction, the sample in the test tube was centrifuged (25 ° C., 4000 rpm, 10 minutes) with a centrifuge (manufactured by Hitachi, Ltd., himac CF7D2) (centrifuge operation). After this centrifugation operation, 4 mL of the supernatant was collected, 2 mL of the PAHBAH solution was added to the supernatant, and the reaction was performed in boiling water for 10 minutes. Thereafter, the supernatant was cooled with water, and the absorbance at a wavelength of 410 nm was measured (absorbance α) using water as a control using an absorptiometer (manufactured by Hitachi, Ltd., U-3010).
Into a test tube, 2 mL of the enzyme solution and 2 mL of the 0.1 M phosphate buffer solution were added and stirred. To the mixture, 2 mL of the phosphoric acid swollen cellulose substrate solution and 1 mL of 2% by weight NaOH aqueous solution were added at the same time. The reaction operation and the centrifugation operation were performed in the same manner as described above, and 2 mL of the PAHBAH solution was added to the resulting supernatant to obtain a blank. Then, the absorbance of the blank at a wavelength of 410 nm was measured using water as a control (absorbance β).
The absorbance β was subtracted from the absorbance α, and this was used as the measured value of the component (A). Separately, a calibration curve is prepared using a known concentration of glucose, and the amount of reduced sugar produced (μM) is calculated from the measured value of the component (A) based on the calibration curve.
