JP4342899B2 - Wrinkle remover composition for textile products - Google Patents

Description

  The present invention relates to a wrinkle removing composition for textiles, a wrinkle removing material, and a method for removing wrinkles. In particular, the present invention relates to a technique suitable for processing a textile product using a rotary dryer.

  Clothes such as shirts, uniform shirts, and blouses are formed through washing / rinsing / dehydration / drying. Especially, clothes mainly composed of cellulose-based fibers such as cotton are prominent, and ironing is eliminated. Cannot be worn. In recent years, shirts that have been subjected to form-stabilization have become widespread, but these also have reduced effectiveness as they are repeatedly worn / washed, and ironing is also necessary. However, since ironing is one of the most labor-intensive housework, a method that can remove wrinkles as easily as possible without ironing is eagerly desired.

  A treatment agent and a treatment method for clothing using a household rotary dryer are already known. Patent Document 1 discloses a textile product treating material for a dryer carrying an antifungal agent. Patent Documents 2 to 6 disclose clothes conditioning products for dryers, which are made of a specific base material impregnated with a softening agent for the purpose of, for example, soft finishing of fiber products and prevention of static charge. Patent Documents 7 and 8 disclose a technique for a dryer sheet in which a flexible substrate is impregnated with a composition containing a specific silicone compound. Patent Document 9 discloses a fabric conditioning composition in which a sheet-shaped flexible base material is impregnated with a specific soil release polymer and a softening agent. However, these techniques do not suggest any wrinkle removal, and satisfactory wrinkle removal effects cannot be obtained even using the techniques of these publications.

  About the method of removing wrinkles from clothing, for example, Patent Documents 10 to 12 impregnate cellulosic fibers with a treatment agent containing a polycarboxylic acid, and heat-treat this to give a wrinkle prevention effect and a shrinkage prevention effect. Is disclosed. Patent Documents 13 to 17 disclose fiber treatment agents using specific polyorganosiloxane compounds. However, these techniques have been developed for industrial use, and do not disclose any method for easily removing wrinkles in ordinary households.

  Patent Documents 18 and 19 disclose a wrinkle-removing aqueous composition that does not require an iron for spraying as a method for easily removing wrinkles at home. Patent Document 20 discloses a technique of a cleaning agent that suppresses wrinkle formation using a nonionic surfactant such as polyhydroxy fatty acid amide as a cleaning component. However, the garments covered by these technologies are wrinkles for wearing wool products such as suits and slacks. Although these garments are effective to some extent, they have a satisfactory effect on the wrinkles of cotton products. is not.

On the other hand, Patent Documents 21 and 22 disclose fabric protection compositions containing oligosaccharides for the purpose of removing wrinkles. It is described that any of these can use a fiber lubricant as required in addition to oligosaccharide, and can include hydrophobic and emulsified silicone in the composition as a desirable fiber lubricant. Hydrophobic silicones and various surfactants used to emulsify the silicones may remain in the treated clothing due to their oily properties, especially on flexible substrates. When the product is supported and used for heat treatment of textile products using a rotary heat dryer, dirt is attached to the composition of the rotary heat dryer tank and the soil is noticeable. And there is a drawback such as more stains derived from the surfactant used to emulsify the silicone, and there is no disclosure of a method for easily removing wrinkles without causing problems in general households. .
