Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an emulsion composition for treating polyester fibers. More specifically, the present invention relates to an emulsion composition for treating a polyester fiber, which can impart an excellent texture to the polyester fiber without lowering its dry friction fastness.

[0002]

2. Description of the Related Art Conventionally, amino group-containing diorganopolysiloxanes, epoxy group-containing diorganopolysiloxanes, and carboxyls have been used as fiber treatment agents for imparting excellent texture such as flexibility and smoothness to natural fibers and synthetic fibers. Organically modified silicone oils such as group-containing diorganopolysiloxanes have been used. For example, JP-A-53-984
In Japanese Patent Publication No. 99, there is proposed a fiber treating agent composed of an amino group-containing diorganopolysiloxane having two or more aminoalkyl groups in one molecule. In addition, the present inventors
First, a polyester fiber treating agent composition comprising an amino group-containing diorganopolysiloxane having an aminoalkyl group in one molecule and an epoxy group-containing diorganopolysiloxane having three or more epoxy group-containing organic groups in one molecule is provided. Proposed (see Japanese Patent Laid-Open No. 5-59673). Such an organically modified silicone oil is diluted with various organic solvents or even emulsified with a surfactant such as a nonionic surfactant or a cationic surfactant in order to uniformly attach it to the fiber. It is also used. However, the one diluted with an organic solvent has a drawback that a fire or an explosion may occur and the working environment is deteriorated, and thus many emulsions have been recently formed. However, when polyester fiber is treated with a fiber treatment agent that is emulsified with a nonionic surfactant or a cationic surfactant, the low-molecular disperse dye dyed on the polyester fiber elutes and the dry friction of the polyester fiber There were drawbacks, such as a decrease in the hardness.

[0003]

DISCLOSURE OF THE INVENTION The present inventors have arrived at the present invention as a result of extensive studies to solve the above drawbacks. That is, an object of the present invention is to provide a polyester fiber with properties such as smoothness, flexibility, compression recovery property, extension recovery property and wrinkle resistance property without deteriorating the dry friction fastness thereof. An object is to provide an emulsion composition for treating fibers.

Yes, it has the effect of imparting smoothness, flexibility, compression recovery (softness of futon), elongation recovery, and wrinkle resistance to polyester fibers. For this component, these diorganopolysiloxanes may be used alone or in combination. When a combination of an amino group-containing diorganopolysiloxane and a carboxyl group-containing diorganopolysiloxane is used as this component, the amino group and the carboxyl group or the carboxylic acid ester group undergo a crosslinking reaction, so that the composition of the present invention is durable on the polyester fiber.
