Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an article for treating textile products that can impart loose flexibility and antistatic effect to textile products such as clothing and towels, particularly in a dryer.

Conventionally, the common method of imparting flexibility (-1) to clothing was to add liquid fabric softener during the washing process.However, with the spread of clothes dryers, the washing masterpiece From the viewpoint of simplification and effective use of the softener, it is used as a softener to impart flexibility and 4 () anti-earth properties when drying damp clothing in the dryer after washing. A variety of absorbent base layers impregnated with softening components have been proposed, such as absorbent base layers with specific absorbent capacities impregnated with textile softeners having melting points of 100'F to 170F. (Tokuko Showa 47-19594
), a non-woven fabric coated with a wax-like substrate and a fabric softener coated on the outside (Japanese Patent Publication No. 47-401)
20) Furthermore, in order to improve usability by lowering the melting point of di-long-chain alkyl di-short-chain alkyl quaternary ammonium salts, which are the major components of textile softeners, fatty polyhydric alcohol esters (JP-A-Show) were developed. 52-118089), lanolin alcohol or its aliphatic carboxylic acid ester (JP-A-52-124998). All of these use quaternary ammonium salts as fiber softening components, but there are also known products that use specific amine salts (
JP-A-53-45496, JP-A-55-51875). This Ushi Unexamined Patent Publication No. 55-51875 discloses that when a specific amine salt is used, it is possible to impart sagging flexibility and antistatic properties without causing an amine odor, and to further improve the performance, quaternary ammonium salt is added. It is described that it is preferable to include salt. It is true that the combined use of an amine salt and a quaternary ammonium salt improves flexibility and antistatic properties, but it is still not sufficient in terms of odor.

In other words, fabric softeners used in clothing dryers are generally manufactured by heating and melting a softening component and impregnating it into an absorbent material such as a nonwoven fabric, and are used in an atmosphere of 40 to 90 degrees Celsius. This is because they are often stored at high temperatures for long periods of time before use, and are subjected to a lot of thermal history, which can cause the amines to deteriorate and increase the odor.

To solve this problem, masking by adding fragrance is performed, but this is not a sufficient solution as it also causes deterioration of the fragrance.

The present invention was made for the purpose of providing an article for treating textile products that solves the above problems, and this invention has oil or fat properties in the softening component consisting of a quaternary ammonium salt and an amine or an amine salt. This was achieved based on the knowledge that by blending a substantially water-insoluble substance with a fragrance, it is possible to obtain an article for treating textile products with a pleasant fragrance that retains the fragrance without changing its quality.
