DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for dyeing a raw material of a fibrous dust control mat, and more particularly to a method suitable for small-lot production of many kinds.

[0002]

2. Description of the Related Art A fibrous dust control mat is
It is widely used as a shoe wipe mat at store entrances, hotel lobby entrances, etc. These mats include, for example, "Welcome," etc.
What displays the user's store name etc. is pleased as a personal mat. However, when displaying the same pattern in large quantities, it is only necessary to show the pattern by dyeing the raw material from the beginning, but when displaying the store name etc., a dust control mat showing the same pattern is excluded except for chain stores etc. It is not used in large quantities.

[0003] In order to manufacture a small amount of a personal mat displaying such various patterns, conventionally, a method of expressing a pattern by implanting fibers of different colors, and a method of printing a dye through a pattern representing a pattern. For example, a method of cutting and pasting a plurality of raw materials having different colors is used.
However, the method based on flocking is not preferable because a dedicated facility is required and the flocking is performed on the glue layer on the raw material. The method of cutting and pasting the raw material cannot prevent the cost from being high due to the trouble and the number of colors that can be used is limited, and there is also a problem that a fine pattern tends to cause peeling.

[0004] In the method of printing with a mold, a free pattern can be expressed with relatively small-scale equipment. However, during the steps of dyeing, washing, and drying, the latex layer provided on the back of the raw fabric is damaged, and the adhesive strength with the rubber mat serving as a base is reduced. The dust control mat is washed when it is soiled by use. However, due to the decrease in the adhesive strength, there is a problem that the rubber mat and the mat are easily peeled off by the washing and the usable period is shortened.

[0005]

An object of the present invention is to improve the dyeing method using the above-mentioned mold and to obtain a method for dyeing a raw material which does not cause a problem due to peeling.

[0006]

The method for dyeing a dust control mat according to the present invention comprises a first step of adhering a raw material to a base rubber, a second step of raising, and printing using a mold by a conventional method, followed by finishing. And a third step of:

[0007]

In the method of the present invention, first, the raw material is bonded to the base rubber. For this bonding, 20kg while heating
/ Cm ² pressure is applied. If the latex layer on the back side of the web is adhered in a perfect state, there is no possibility that peeling will occur in the subsequent washing and drying steps. However, due to the high pressure bonding, the hair of the raw fabric is also pressed, and when the dye is to be partially dyed with a mold, the dye mixed in the glue is pressed in through the mold at high pressure. Is produced, and if it is hard, the penetration of the dye is poor and the dyeing becomes insufficient. In the present invention, the above-mentioned problem is solved by raising the hair of the press-bonded raw fabric. Raising may be performed mechanically or by washing. The material thus brushed can be printed by a conventional method.

[0008]

The present invention will be described in detail below with reference to embodiments. According to the order form, the designated design and characters are input into a personal computer or the like as figures by an appropriate method. After deciding the design on the display, the output is used to make the mold.
A white raw fabric is adhered to a synthetic rubber base, and the fur supplied in a state in which the hairs are also pressed is brushed with a metal brush, in the simplest case. Brushing can be performed not only by such a mechanical method but also by washing the raw material. However, since the mat adhered to the base is heavy, mechanical brushing is used here. The previously prepared mold is placed on the raised material, and the dye mixed in the glue is stretched while being pressed against the material surface with a squeegee. After squeezing the required number of colors, the mat is steamed at 100 ° C. for 20 minutes. The steamed mat is washed with water, and the remaining dye and glue are washed off. To increase the fastness of dyeing, immerse it in a water tank containing a fix (dye fixing agent). This is dehydrated and dried to complete the dyeing. Among the above steps, the steps after squeezing are the same as those of the conventionally known method, and thus the details are omitted.

[0009]

As described above, the method of dyeing a raw material according to the present invention enables the mat and the base to be bonded before dyeing by adding a brushing step, and performs printing by a conventional method after bonding. Became possible. For this reason, it is possible to perform low-cost dyeing of a small variety of personal mats without the need for a large and expensive apparatus.
