Description

DETAILED DESCRIPTION OF THE INVENTION The present invention consists of 1. Creates a pattern when textile products are wet,
This invention relates to a wet pattern processing method.

Conventionally, various methods have been proposed for causing patterns to appear when clothing such as swimsuits and diaper covers, or textile products such as umbrella fabric and tent fabric are wetted. For example, JP-A-59-125
984 as an example. However, in the conventional method, a cleaning process is required mainly due to the use of a sizing agent during printing, recontamination occurs during soaping, and the resulting product lacks sharp outlines. was also not satisfactory.

In conventional textile printing methods, a sizing agent, an oil agent, an emulsifier, water, and a dye called a sizing agent, a dye and water, or an emulsion paste are used to fix the printing paste with the sizing agent and prevent it from scattering during drying. However, this glue itself cannot be used after dyeing unless it is washed off by soaping, as it deteriorates the texture and fastness of the product. That is, a soaping period was required. On the other hand, when a water repellent, a crosslinking agent, etc. having a water effect were added to this printing paste, the printed portion did not have a complete water effect. That is, when soaping with a sizing agent, there have been disadvantages such as the water repellent agent falling off or re-contaminating together with the sizing agent during soaping, and further, the outline becoming unclear.

Means for Solving the Problems The present inventors have arrived at the present invention as a result of intensive research aimed at solving the drawbacks of the prior art.

According to the present invention, a printing paste consisting of a water repellent, an oil agent, an emulsifier, water, and a crosslinking agent is printed on a fiber fabric and fixed by heating. A fiber fabric that develops a pattern when wet is obtained.

In the present invention, a reducer is prepared from a water repellent, an oil agent, an emulsifier, a crosslinking agent, and water, and this is printed as a printing paste with perfect printing characteristics and appropriate viscosity and flow characteristics. It is dried and baked. As a result, the water repellency of the printed area does not deteriorate in any way.
A pattern with good water dispensing performance can be created. This pattern appears when the material is wet, but depending on the application, the pattern can also function as a sensor to detect the wet state. In terms of uses, it works as a ceresor effect in diaper covers, umbrella fabrics, swimwear, etc. where water is used.

To explain in more detail, in the present invention, as the water repellent, for example, a silicone water repellent such as a fluorine water repellent such as the following margin is used, and as the oil agent, for example,
An oil agent with a boiling point of 120 to 220°C is used, such as turn, molten oil, etc. Preferably, an oil agent with a boiling point of 140 to 220°C is used. As an emulsifier, a nonionic agent having an ester bond or an ether bond is used. By type, HLB4~1
It is preferable to use one having an HLB of 8, preferably an HLB of 12 to 18.

As the crosslinking agent, for example, a melamine resin or an imine resin is preferably used, and the durability of the resulting pattern is improved by adding this agent.

A printing paste having such characteristics is prepared, and this paste is printed on a fabric using a conventional method. Thereafter, by drying and baking, the printed area can be made water repellent.
