Abstract

PROBLEM TO BE SOLVED: To prevent a mat from losing its interior decorating function due to discoloration of the ground color portion of a pile and improve the accuracy of design by providing a colored design to the pile composed by tufting threads containing a pigment. SOLUTION: In making a rental mat, BCF nylon solution-dyed multifilaments having a trefoiled cross section for example is made by a solution dyeing method, and used as pile threads, and a raw fabric for the mat is made by tufting a ground fabric with them. And then a random black design is given to the pile of the raw fabric for a mat by a jet dyeing method using a black acid dye. And then plating is given thereafter. At this time, however, an acrylonitrile butadiene rubber(NBR) latex of about 700 g/m<2> (10% solid content) is applied to the reverse of the raw fabric, and water is dried. And then packing is made, and a desired rental matt is obtained by cutting an NBR rubber sheet so that about 15 mm selvage of the NBR rubber may remain in the surrounding of the raw fabric.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rental mat with a colored design and a method for manufacturing the same.

[0002]

2. Description of the Related Art Rental mats, which are periodically replaced with clean ones, are widely used because they are maintenance-free and maintain the cleanliness of entrances of stores and offices. I have. On the other hand, in recent years, not only a dust removing function but also an interior function has been demanded of the mat. In the past, cotton and vinylon have been widely used as fiber materials for rental mats, but recently, nylon has become the mainstream due to the dust scraping effect due to the bulkiness of the fiber, good color development and durability. It has become to.

By the way, in order for a mat to exhibit an interior function, a coloring design applied to a pile surface is very important. The coloring design was generally applied together with the ground color by dyeing with a dye.

[0004]

However, rental mats are used repeatedly while being exposed to sunlight, and are repeatedly collected and washed. Therefore, excellent light fastness and washing fastness are required. However, in the case of rental mats that have been given a ground color and a colored design by dyeing with dyes, both of them have low robustness, and the discoloration and fading of the ground color on the pile surface is particularly conspicuous, and the interior function deteriorates. there were.

Therefore, a method has been proposed in which a pile yarn containing a dye is produced by a so-called "stock solution coloring method" and a ground color and a colored design are formed using the pile yarn. The stock solution coloring method is a method in which a dye is kneaded when a raw yarn is spun and a dye is contained in the raw yarn.Specifically, a resin material containing a dye and a colorless resin material are melted. Then, the original yarn is formed (or spun). But with this method,
Although light fastness and washing fastness are dramatically improved,
Since the form of the design must depend on a mat manufacturing machine, for example, a tufting machine, there are problems such as limitations on the accuracy of the design of characters and patterns, the types of colors that can be used, and the like.

The present invention provides a rental mat, which can prevent a decrease in interior function due to discoloration and fading of a ground color portion of a pile surface, can improve design accuracy, and can increase the types of colors that can be used, and a rental mat therefor. An object of the present invention is to provide a manufacturing method capable of obtaining such a rental mat.

[0007]

According to the first aspect of the present invention,
On the pile surface configured by tufting yarn containing dye,
A rental mat characterized by a colored design.

According to a second aspect of the present invention, there is provided a method of producing a pile surface by tufting a yarn obtained by melting and molding a resin material containing a pigment and a colorless resin material, and forming the pile surface. Providing a colored design by dyeing with a dye.

[0009] In the rental mat having the above structure, the ground color portion is constituted by the yarn containing the pigment.
The ground color portion is hardly discolored. Therefore, even if the coloring design obtained by dyeing has some discoloration, the color of the ground color portion is maintained, and the interior of the mat itself hardly deteriorates visually. In addition, since the coloring design is applied by dyeing, the design accuracy is high,
There are also many types of colors that can be used.
