Description

  The present invention relates to a method for flavoring textile products.

  In recent years, the preference for fragrances has been increasing, especially among younger generations, and it is common households to add fragrances that are desirable to textiles such as clothing. As a fragrance method, it is common to spray a fragrance component onto an object with a trigger spray or the like, but the detergent or softener used in the washing process has a fragrance function and is attached to a textile product. Incense is also done. However, when a detergent or softener is used in the washing process, a different odor different from the fragrance of the detergent or softener itself may adhere to the clothes.

  Patent Document 1 discloses a technique for improving the residual fragrance of a fragrance by using a bleaching composition containing an aminocarboxylic acid type chelating agent, and the object to be cleaned is added to a cleaning liquid prepared from the composition. It is described that it can be immersed for about 12 minutes. Patent Document 2 discloses a technique using silicic acid for the purpose of improving the stability of effective oxygen of the bleaching composition. The publication also describes a composition containing baking soda and an alkanoyloxybenzenesulfonic acid type bleach activator.

  However, a bleaching composition containing a large amount of an oxidizing bleaching agent or a bleaching activator generally has a problem of decolorization of colored clothes, so that the immersion time is considered to be about 2 to 3 hours. Yes. Actually, even the embodiment of the cited document 1 is washing in a normal course of a fully automatic washing machine, and bleaching treatment by long-time immersion is not performed.

  Further, in Patent Document 2, an alkanoyloxybenzenesulfonic acid type bleach activator and an aminocarboxylic acid type chelating agent diethylenetriaminopentaacetic acid are used in combination, but such a specific aminocarboxylic acid type chelating agent is contained. When the composition to be used is used in the immersion treatment, unfavorable fragrance often occurs, which is promoted as the immersion time becomes longer. In Patent Document 2, there is no mention of technical problems relating to the flavoring of the fragrance during bleaching and the means for solving it, and there is also shown any effect when the immersion treatment is actually performed with a composition containing the fragrance. Not.

  The present invention provides a fiber product flavoring method capable of flavoring a desired scent to a target fiber product while maintaining the color of the colored fiber product without losing the bleaching effect during the bleaching process. It is to provide.
