JPH06272177A - Production of gigged fabric having multiple color effect - Google Patents

Abstract

PURPOSE:To obtain a fabric solely gigged layers of which is dyed and rich in multiple color effect by dying a gigged fabric consisting of polyester fibers with a dischargeable and an undischargeable dyes, then applying a discharging agent on the gigged surface and heat-treating it. CONSTITUTION:One surface of a knitted fabric consisting of polyester fibers is gigged, then dyed e.g. with dischargeable disperse dyes (blue and yellow dyes) and an undischargeable blue disperse dye. After drying, a discharging agent containing a reducing agent is applied solely on the gigged surface of the gigged knitted fabric and the fabric is heat-treated to obtain a gigged fabric excellent in multiple color effect with blue-colored gigged layers on a green ground color and having high grade feeling superior in artistic design feeling.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raised fabric having a multicolor effect which has a design and a high-class effect by giving a raised surface of a knitted fabric made of a polyester-based synthetic fiber a multicolor effect. The present invention relates to a manufacturing method of.

2. Description of the Related Art Heretofore, many methods for producing a raised fabric having a multicolor effect have been proposed, and products are actually on the market. However, these include those obtained by dyeing a two-component yarn, or those using a mixed yarn of chromatic polyester primary dyed yarn and non-primed polyester yarn.
All of them are expensive in terms of cost, have no high-class feeling, and lack in design.

[0003]

A method for producing a raised fabric having a multicolor effect of the present invention, which has been proposed to solve the above-mentioned problems, comprises a knitting fabric made of polyester synthetic fibers on at least one side thereof by a raising machine. Raised, and then the raised fabric is dyed with a dye selected from a large number of disperse dyes and decomposed by a discharge agent, and a dye having durability to the discharge agent, and the raised fabric is raised. When the discharge agent is applied to the layer surface so that it adheres to the surface and heat treated,
Only the dye that is not durable to the discharge agent in the area where the discharge agent is attached in the napped layer is decomposed, and the napped layer that has the extracted and non-extracted areas and the unextracted background area Let it form. Then, by performing washing and finishing treatment, a raised fabric having a multicolor effect can be obtained.

The present invention will be described in more detail below. As the cloth made of the polyester-based synthetic fiber described in the present invention, there is no particular limitation on the weave mode of the woven fabric, and for example, any woven fabric such as plain weave and twill weave can be used. In the knitted fabric, either warp knitted fabric or circular knitted fabric can be used. In both cases, it is necessary to select a fabric suitable for raising hair. Raising can be performed using, for example, a cloth raising machine or a sanding machine. In addition, by changing the raised state of the surface of the cloth, the surface attachment state of the discharge agent is changed, so that various changed surface feelings can be obtained. For example, by making the fluff state a chinchilla tone, a further multicolor effect can be obtained.

Dyeing of the napped cloth is performed by a dye which is decomposed by a discharge agent selected from a large number of disperse dyes and a dye which has durability against the discharge agent. In the present invention, as the discharge printing agent, for example, a tin-based reducing agent, a sulfin-based reducing agent, an alkaline agent, etc. can be used. The dyeing agent is applied after the dyeing of the napped cloth, and the napped textile may be impregnated with a dry urethane resin or a wet urethane resin in order to give elasticity and elasticity before the application of the discharge agent. .

It is essential that the discharge-printing agent containing the reducing agent is surface-coated only on the raised layer portion of the raised dyed fabric.
As a coating method, a rotary printing machine, a roll printing machine, a kiss roll coater, a gravure roll coater, or a screen printing machine can be used. Further, if the amount of the discharge agent adhered is too large, not only the raised layer portion of the cloth but also the background portion is discharged and the multicolor effect cannot be obtained, and if it is too small, the discharge effect cannot be obtained. Therefore, the coating amount is 5
The range of 60 g / m ² is preferable, and particularly 10 to 30 g / m
A range of ² is preferred. Then, it is dried.

The subsequent heat treatment after drying may be either dry heat or wet heat, and the dry heat treatment conditions are set temperature 190 to 200 ° C.
In addition, the setting time is 1 to 3 minutes. The wet heat treatment includes high-pressure steam heat treatment and high-temperature steam heat treatment, and the former treatment conditions are set temperature of 125 to 130 ° C. and set time of 20 to 30 minutes, and the latter is set to 170 to 180 ° C. The setting time is 6 to 10 minutes. Thereafter, the discharge agent on the fiber and the remaining dyes are removed by washing, and the resultant is dried, and then a finishing treatment is performed. Finishing treatment, if necessary, softener, water repellent,
Treat with antistatic agent.

EXAMPLES Examples of the present invention will be described below. In addition, here,% means owf (weight of fiber), and mere parts indicate parts by weight.

Example 1 Threading made of polyester fiber 75d / 96f, 50
The tricot-satin knitted fabric with the d / 24f interwoven was subjected to a raising treatment with a needle cloth to obtain a knitted fabric having a raising layer.
