ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a process for producing printed articles. More particularly, the present invention relates to a process for producing printed articles which enables printing cloths having a rough surface such as frieze cloths, pile cloths, knit cloths, towel cloths, felt cloths and blanket cloths while the proper feel of the cloth is maintained and provides printed articles having excellent fastness and appearance.
2. Description of Related Art
As a greater variety of fiber products are produced and the products become more fashionable in recent years, it is required that printed articles be made from cloths having a rough surface such as raised frieze cloths, flocked pile cloths, bulky knit cloths, towel cloths, felt cloths and blanket cloths.
However, when such a cloth having a rough surface is printed in accordance with a conventional process such as pigment printing and printing using a rubber printing material, problems arise, for example, in that, due to the rough structure of the surface, pigments are attached to depressed portions in a greater amount to deteriorate the feel of the cloth or only to tip portions of raised fibers and clothing articles having poor appearance and poor patterns are obtained. When the entire surface of a cloth is laminated with a film or coated with a soft resin to smooth the rough surface of a cloth, the properties of the cloth is markedly deteriorated. Therefore, the one-point printing is rarely conducted in printing a cloth having a rough surface. When a cloth having a rough surface is printed, it is necessary that a process such as the film transfer printing and a process using a print flocky be used.
Therefore, a process which enables direct printing on cloths having a rough surface while the proper feel of the cloths is maintained, provides printed articles exhibiting excellent fastness and appearance and can produce printed articles rapidly even when many types of printed articles are produced in small quantities has been required.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a process for producing printed articles which enables printing cloths having a rough surface such as frieze cloths, pile cloths, knit cloths, towel cloths, felt cloths and blanket cloths while the proper feel of the cloths is maintained and provides printed articles having excellent fastness and appearance.
As the result of intensive studies by the present inventors to overcome the above problems, it was found that, when an under coat is formed on a cloth having a rough surface with a foamed composition of a resin emulsion by printing and a top coat is formed on the formed under coat by printing, the proper feel of the cloth is not adversely affected even when the cloth is directly printed and a printed article exhibiting excellent fastness and appearance can be produced. The present invention has been completed based on this knowledge.
The present invention provides:
(1) A process for producing printed articles which comprises forming an under coat on a cloth having a rough surface with a foamed composition of a resin emulsion by printing, drying the formed under coat, forming a top coat on the dried under coat by printing and drying the formed top coat;
(2) A process described in (1) wherein the composition of a resin emulsion is an emulsion of an acrylic ester resin;
(3) A process described in (2) wherein the acrylic ester resin has a glass transition temperature of −40 to 20° C.;
(4) A process described in (1) wherein the composition of a resin emulsion comprises foaming agents, foam stabilizers and thickeners;
(5) A process described in (1) wherein the foamed composition of a resin emulsion has an extent of foaming of 1.2 to 4 times;
(6) A process described in (1) wherein the top coat is formed by pigment printing, rubber printing or printing with foaming by heating;
(7) A process described in (1) wherein the top coat which has been formed by printing and dried is heat treated; and
(8) A process described in (1) wherein the cloth having a rough surface is a frieze cloth, a pile cloth, a knit cloth or a towel cloth.
