DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray type sizing composition. More specifically, the present invention relates to a spray type sizing composition that can easily remove attached dirt.

[0002]

2. Description of the Related Art A spray type paste is convenient because it can be easily used. The spray type paste is suitable for partial gluing, particularly for gluing collars and sleeves. These collars and sleeves are in close contact with the human body and are subject to friction and the like, so if dirt adheres, it is difficult to remove the dirt during ordinary washing, and it is customary to partially wash with a brush or the like. The main component of commercially available spray-type pastes is a modified starch whose viscosity is reduced, and such pastes generally have the property of facilitating the removal of dirt. It is not possible to expect perfection for such dirt. Conventionally, many attempts have been made to improve the dirt-removing effect of such a sizing agent containing modified starch as a main component. For example, JP-A-2-112475 discloses water-soluble polymer substances such as a maleic acid polymer, a hydrolyzate of a copolymer of acrylic acid and maleic anhydride, and a hydrolyzate of a maleic anhydride polymer. There is a description of a solution containing This is intended to enhance the dirt removing effect by combining a polymer having a film forming property with a dispersant having a function of dispersing the dirt itself and preventing recontamination. According to this technique, although the dirt-removing effect is considerably improved as compared with the conventional glue, it has not yet solved user dissatisfaction in home washing or the like.
