Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing method for lightening the printed part of a cellulose fiber product and darkening the part other than the printed part.

A printing paste made of caustic soda and a sizing agent is printed on a cellulose-based textile, and after a predetermined period of time, the printed area is shrunk by washing with water, and the textile is immersed to make the printed area a dark color, and the area other than the printed area is dyed. A printing method that makes the color lighter is known.

However, when using this printing method to make the base part a dark color and only the pattern part a light color, if the base part is wider than the pattern part, it may be difficult to print the entire textile. This method had the drawback of requiring a large printing mold and consuming a large amount of printing paste.

The present invention is intended to improve the above-mentioned drawbacks, and it is possible to lighten the pattern part and make the background part dense and dark-colored by using a printing mold of the size of the pattern, and also uses a small amount of glue. The purpose of this invention is to provide a method for printing cellulose-based textiles that can be used to create patterns.

The present invention involves printing a sizing agent containing a water-filling agent on the surface of cellulose-based textiles, heating and fixing the imprinted sizing agent, and then
This textile product is treated with alkali to shrink the textile product other than the printed part, and the textile product is washed with water to remove the stuck glue and dyed, and the printed part is colored in a light color other than the printed part. It is called S-mold that dyes a deep color.

The material of the present invention is a textile product such as a woven fabric or knitted fabric made of cellulose fiber such as cotton, linen, or rayon, which is subjected only to a scouring process and is not mercerized. In addition, the size agent containing a water filler has a 2000 to 700
It is a water-soluble glue that has a viscosity of 0 cps and forms a hard film on the surface when it is filled with a strong alkaline aqueous solution and heated and dried.

The printing method for printing the paste containing the water-filling agent can be carried out by various printing methods such as roller printing and automatic screen printing. In addition, heat fixation of the adhesive after printing is carried out by pre-drying at 100°C or lower to remove moisture in the adhesive, and curing for several minutes at 150°C or higher to form a hard film on the adhesive surface. .

The alkali treatment of the textiles to which the size has been fixed by heating is carried out using a normal mercerizing device for textiles or knitted fabrics, preferably in a caustic soda solution of 20-30Be at 15-25°C. Treat under tension for 15 minutes, then neutralize after steaming. In addition to a caustic soda solution, an alkali metal hydroxide such as KOH can also be used to achieve approximately the same level of treatment.

As a result of this alkali treatment, the portions of the textile product to which the glue is not adhered shrink, and the density of the fiber tissue becomes lower. on the other hand,
The part to which the paste is fixed is filled with alkaline solution, and the density of the fiber structure remains unchanged.

The sizing agent after the alkali treatment is removed by washing with warm water at around 40° C. and, if necessary, a scouring agent under the same conditions as the normal desizing step or scouring step. The textile from which the size agent has been removed is preferably once dried and then dyed in phase to the desired color. As the dyeing method, a padder is preferable, but a method using other dyeing machines such as a wince or a jigger may also be used.

Due to this dyeing, the part of the ground that is not printed becomes denser and dyed in a dark color, while the part of the pattern that is printed is dyed in a lighter color compared to the ground part without changing the density. It can produce some unique patterns.

As described below, according to the present invention, conventional Silken)
Compared to the printing method that applies KaT, it is possible to create a new sense of plain pattern dyeing with differences in shading and density by making the pattern part lighter in color and the ground part more dense and darker in color. can. Another advantage is that patterns can be created with a small amount of glue.

EXAMPLES Hereinafter, in order to clarify aspects of the present invention, examples will be shown and explained.

(Example I) 52/23' cotton voile is desized and scoured, then this fabric is once dried, and a pattern is made on the surface with a sizing agent of 3000 to 500 oc ps adjusted as follows. to be stamped.

After being stored for 10,000,020 hours, the fabric is taken out, washed and dried, resulting in a new type of textile product with a three-dimensional pattern in which the ground and pattern areas are each different in shade, and the ground area is denser. It will be done.

(Example II) A printing paste with a viscosity of 4,000 to 6,000 cps adjusted as follows was printed on the back side of a double knit of 50% polyester and 50% cotton, with a polyester surface and 100% cotton on the back. After printing, pre-drying and curing in the same manner as in Example I, alkali treatment is applied, and polyester and cotton are dyed in different hues at 100°C for 60 minutes using the method described below, resulting in different colors on both sides and differences in shading on the back side. A special knitted fabric for clothing can be obtained with patterns with different density.
