Description

  The present invention relates to a treating agent composition for textiles, and more particularly to a softener composition suitable for use in textiles such as clothing. More specifically, the present invention relates to a softener composition that is excellent in deodorizing and deodorizing effects.

As a method of deodorizing and deodorizing textile products, attempts have been made to reduce bad odors by sensory deodorization, physical deodorization, chemical deodorization, biological deodorization, etc. However, the current situation is that no satisfactory one has been obtained. Thus, there is still a high need for reducing the bad odor of textile products.
Each deodorization / deodorization method has a different deodorization / deodorization mechanism. For example, sensory deodorization is a method of preventing a bad odor from being felt by a fragrance or the like, but may be easily felt depending on the odor. Physical deodorization is a method to prevent the generation of odor by incorporating malodorous molecules into the pores existing in the molecule or base, but conventionally used silica and cyclodexton are Depending on the malodorous component, it may not be able to be taken into the hole. Chemical deodorization is a method of weakening the odor or making it odorless by chemically reacting with a malodorous component, but the malodorous component is composed of all components, and there are those that do not chemically react. Biological deodorization is a method of reducing the number of bacteria on the skin and suppressing growth, thereby suppressing the generation of odor due to decomposition of sweat or the like, but is ineffective when bacteria or the like are not involved.

  Accordingly, an object of the present invention is to provide a softener composition that can provide an excellent deodorizing and deodorizing effect against various odors.

The present inventors blended a specific glucan called highly cyclic branched dextrin classified as a physical deodorant base material into a softener composition, and applied it to the fiber to prevent various odors. It has been found that excellent deodorizing and deodorizing effects can be obtained.
In addition, in order to apply a functional substance to a textile product during washing, a cationic base material or the like is usually added to the textile product treatment composition. It has been found that the addition of a compound further improves the deodorizing and deodorizing effect of the highly cyclic branched dextrin.
The present invention has been completed based on such novel findings.
