Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dyeing method for dyeing a fabric in a marbling pattern and at the same time imparting a soft texture to the fabric.

Conventional dyeing methods for textile products include a pre-dyeing method in which a fabric is made by dyeing the raw yarn and then weaving and knitting, and a post-dying method in which the fabric is dyed.

The first dyeing method can obtain a depth of color that cannot be obtained with the piece dyeing method, and can also produce marbled tones on the fabric, but this method is expensive when the production lot is small (
Another disadvantage is that it takes time from receiving an order to producing a product, making it difficult to respond to changes in market conditions and trends.

On the other hand, in order to achieve marbling-like dyeing using the piece dyeing method, it is known to dye different materials by blending, twisting, and interweaving, but in this method, the product value of the product depends on the combination of the constituent materials. Depends on it.

In addition, the printing method, in which a paste containing a dye is printed on the fabric and dyed, allows multicolor and pattern dyeing; A method to make it appear has not yet been developed.

On the other hand, there are known finishing methods for imparting a soft texture to fabrics, such as applying various fabric softeners after dyeing, or making the fabric soft by steaming or mechanically kneading. It may have an adverse effect on the fibers such as a decrease in elasticity, the durability of the softening effect may be poor, and there is a risk of adverse effects on the human body such as skin disorders.

Regarding the latter, it is possible to soften the fiber without adversely affecting the fiber, but it has disadvantages such as requiring a large investment in installing machinery, increasing the number of steps, and increasing the cost.

It is also known that emery processing can be used to make the surface of the fabric fluffy to obtain a fabric with a suede-like soft texture, but this method directly damages the surface of the fibers, resulting in a decrease in the strength of the fabric. There are drawbacks to doing so.

The method of the present invention compensates for the shortcomings of the pre-dyeing method, allows a single material to develop marbled tones that cannot be obtained with the conventional post-dyeing method, and at the same time does not have any negative effect on the processed material (i.e., has good flexibility). This is a dyeing process that gives it a texture.

In other words, in the normal print dyeing method, which involves printing a dye containing a sizing agent onto a textile fabric, fixing the dye by steaming or dry heat treatment after drying, and then washing the unfixed dye and sizing agent, the sizing agent is After printing and drying, the printed surface of the textile fabric is fluffed by emery processing, minute portions of the printing dye and paste are mechanically removed, and then fixed and washed in the usual manner. As a result, the fiber fabric is dyed in a marbling tone, and at the same time, a soft texture effect is imparted.

In the method of the present invention, emery processing should be carried out after the dye containing a sizing agent is printed on the fabric and dried, and before the dye is fixed. The dye migrated to the area where it was removed, making it impossible to obtain a good marbling tone.

Even if emery processing is performed after fixation of the dye, it will only fluff the surface and will not produce a marbling tone.

In the method of the present invention, only the surface condition of the fabric is changed to improve the feel of the fabric, so there is no adverse effect on the processed material that would occur when using a fabric softener (softening treatment is possible, and the use of glue) Because emery processing is performed in a state containing
Compared to normal emery processing, there is no risk of strength loss.Furthermore, since the surface is rubbed while it is hardened, the fuzz can be removed evenly and neatly, and there are fewer wrinkles (easier to process). It is.

The inventors of the present invention applied emery processing to a fabric, then printed a paste containing a dye using a normal method, dried it, fixed it, washed it, and dried it. The texture and dyeing effect of a fabric obtained by printing a paste containing a dye, drying, fixing, washing, and drying, and then emery processing and a fabric processed by the method of the present invention were compared. As a result, the fabric processed by the method of the present invention was the most flexible, had short and uniform fuzz, had little loss of strength (and had excellent marbling effect).

In the method of the present invention, synthetic fibers such as polyester, polyamide, polyacrylonitrile, viscose rayon,
It is possible to process fiber fabrics that can be dyed using the printing method described below, such as recycled fibers such as cupro, semi-synthetic fibers such as acetate and triacetate, and natural fibers such as cotton, linen, silk, and wool.

The printing method referred to in the present invention is a printing method in which a size agent and a dye are printed on a fiber fabric, dried, the dye is fixed by steaming treatment, dry heat treatment, etc., and then the unfixed dye and size agent are washed and removed. There are roller printing, flat screen printing, rotary screen printing, paper pattern printing, etc.

The glue to be used may be a general one suitable for the printing method, the object to be processed, and the dye used, such as sodium alginate, CMC, locust bean, pretty rubber,
Examples include tragacanth rubber and PVA.

Drying after dye printing is performed by a commonly used method.

After printing and drying, the printed surface of the fabric is brought into contact with an emery roller (sandpaper roller) and rubbed to mechanically remove some of the paste and dye, giving it a marbled tone and softening the texture. Plan.

After emery processing, the dye is fixed using a conventional steamer (1 high temperature steamer, tenter, etc.), and then washed with water to remove unfixed dye and paste, followed by drying.

The present invention will be described in detail below with reference to Examples.

Example 1 A twill fabric woven with 150d/48f polyester processed yarn was subjected to normal relaxing scouring and drying, and then using a flat screen printing machine, a color paste with the following formulation was printed on the entire surface of the fabric, and then dried. I did it.

Corner and glue prescription The original glue is Sunrose AIOM (CM made by Sanyo Pulp ■)
It was prepared by mixing and stirring 27 parts by weight of C-based glue, 27 parts by weight of Indalliki AGBV (locust bean-based glue manufactured by Cesarpinia), 24 parts by weight of sodium alginate, and 922 parts by weight of water.

After drying, the printed surface of the treated cloth was brought into contact with an emery roll made of No. 180 sandpaper at a speed of 200 times/min.

Next, steaming treatment was performed at 130°C for 30 minutes to fix the dye, followed by washing with water in a wince, followed by hot water washing (80°C), followed by reduction cleaning at 80°C for 20 minutes using the following recipe, followed by hot water washing. (80°C), washed with water, and dried.

Reduction Cleaning Prescription The following samples of Comparative Examples 1 to 3 were prepared for comparison.

Comparative Example 1 The same polyester twill fabric as in Example 1 was subjected to the usual relaxing scouring and drying, then one side was subjected to emery treatment in the same manner as in Example 1, and then the worn side was subjected to the same emery treatment as in Example 1 using a flat screen printing machine. Color paste was printed on the entire surface and then dried.

Subsequently, the dye was fixed in the same manner as in the example, followed by washing and drying.

Comparative Example 2 The same polyester twill fabric as in Example was subjected to relaxing scouring and drying in the usual manner, then colored starch was printed and dried in the same manner and treatment as in Example 1, and then the fabric was heated at 130°C for 30 minutes. Steaming was performed to fix the dye.

Subsequently, the printed surface was subjected to emery processing under the same conditions as in Example 1, and further washed and dried.

Comparative Example 3 The same polyester twill fabric as in Example 1 was subjected to normal relaxing scouring and drying, and colored starch was printed using the same treatment and method as in Example 1. After drying, the dye was fixed, and then washed and dried. I did this.

Finally, emery processing was performed in the same manner as in Example 1.

The treated fabrics processed in Example 1 and Comparative Examples 1 to 3 had the results as shown in the table below. Example 1 showed a good marbling effect and a good texture, but Comparative Examples 1 to 3 showed a marbling effect. There were no problems, and Comparative Example 2 was only slightly satisfied in terms of feel.

The tear strength is determined by the Penschrum method (JIS-IL-1
079), and the hand was determined mainly by softness and touch through a sensory test.
