Description

  The present invention relates to a fiber product treating agent composition for imparting a soft feeling to a textile product such as clothing and reducing wrinkles, and in particular, a fiber product treating agent composition for reducing wrinkles generated when using a heating dryer. About.

  In recent years, drum-type washing / drying machines equipped with a drying function are rapidly spreading. However, when washing or drying is performed using a heating dryer provided in these washing dryers (hereinafter, the heating dryer described in this specification may be simply referred to as a dryer), Since there are wrinkles and shrinkage, and the towel is wrinkled, there is a need for a finishing agent that can solve this problem.

  The wrinkles remaining in the clothes after washing give an unpleasant feeling when worn, but the wrinkles generated when using the dryer are folded wrinkles that are deeply cut into the clothes, and are particularly severe in nature. The wrinkles at the time of using this dryer are peculiar that can not be seen when hanging and drying by ordinary washing. Therefore, in order to avoid this wrinkle problem, the washing and drying machine user, for example, when using the washing and drying machine, (1) Do not pack a large amount of clothing, (2) In the state of containing moisture during drying The clothes are taken out from the clothes and hung and dried.

  On the other hand, recent new washing / drying machines have become larger year by year, so that many clothes can be washed and dried at once. However, as described above, if a lot of clothing is dried in a state where it is put in the tank, a wrinkle problem occurs. Therefore, practically, it takes advantage of the convenience of washing machines and dryers that are recommended by manufacturers of washing machines and dryers, such as the ability to do everything from washing to drying with a single button, and the advantage of increasing the size of washing clothes and drying them at once. There is no current situation that can be. Accordingly, there is a demand for a finishing agent that can reduce wrinkles reliably as well as providing flexibility under any conditions of use of the washer / dryer.

Several fiber product treating agents and treatment methods developed for use in washing and drying machines are already known. Patent Document 1 discloses a softener for a dryer that uses a specific base material such as a nonwoven fabric impregnated with a softener. Patent Document 2 discloses a dryer sheet in which a flexible substrate is impregnated with a composition containing a specific silicone compound. Patent Documents 3 and 4 disclose a method of applying water-insoluble polymer nanoparticles as a finish composition. Patent Document 5 discloses a method of using a nonionic polysaccharide other than starch as a finish composition. Patent Document 6 discloses a method in which a water-soluble cellulose derivative is used in combination with a trace amount of silicone. Patent Document 7 discloses a fiber product treating agent that improves the shape loss of washed clothes using water-soluble processed starch, derivatives thereof, and cellulose derivatives. Patent Document 8 discloses an anti-wrinkle finish for a composition in which a water-soluble polymer is used in combination with a nonionic active agent and a silicone compound. However, in the method using these compositions, although the wrinkles after washing can be reduced to some extent, the effect of reducing the folding wrinkles peculiar to the dryer is poor, and there is no wrinkle required by the washing / drying user, and the texture ( The finish of clothing with good flexibility cannot be obtained. Furthermore, since there is no description as a washing / drying machine application, the wrinkle removing effect under the conditions of use of the drying machine is unknown. Patent Document 9 discloses an anti-wrinkle finish for a composition comprising a cationic active agent containing an ester group and a silicone compound in combination with a water-soluble polymer. However, the cationic active agent used in this composition is limited to the use of an agent containing an ester group and is different from that used in the present invention.
Furthermore, as a method for reducing wrinkles in use other than a dryer, a method of spraying an aqueous medium composition containing an effective amount of silicone and a film-forming polymer as disclosed in Patent Document 10 by a trigger method is also known. . However, since there is no description as a laundry dryer application, the wrinkle removing effect under the dryer usage conditions is unknown.
