Description

  The present invention relates to a wrinkle removal composition and a wrinkle removal method that can remove wrinkles of a textile product and can effectively remove wrinkles without performing a heat treatment such as ironing.

In general, dry cleaning clothes such as suits are difficult to wash with water at home, and methods for removing wrinkles generally include heat treatment such as ironing and steam press. As a means of stretching wrinkles of clothing without heat treatment, it is only allowed to leave after spraying a composition combining water with a specific water-soluble solvent such as hexylene glycol and isoprene glycol in Patent Document 1 on the wrinkle portion of the clothing. A method for removing the wrinkle is disclosed. However, although this method can remove light wrinkles on clothes, it is difficult to completely remove deep wrinkles. Patent Document 2, Patent Document 3, Patent Document 4, and Patent Document 5 disclose a fabric wrinkle removing composition and method. In these methods, wrinkles are removed by spraying the composition onto a fabric and then hanging it to dry naturally or by ironing, but only natural drying can sufficiently remove wrinkles. In addition, ironing is very effective for removing wrinkles, but it is a troublesome work and is insufficient for restoring the texture.
