Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transferring and printing a composite fabric comprising flame-retardant fibers mainly composed of flame-retardant acrylic fibers and polyester fibers.

[0002]

2. Description of the Related Art In recent years, flame-retardant composite fabrics composed of general-purpose flammable polyester fibers and flame-retardant fibers mainly composed of highly flame-retardant acrylic fibers have been developed. Materials such as curtains, upholstery, sheets, futon lands, and covers are becoming mainstream.

[0003]

However, since this flame-retardant composite fabric uses flame-retardant acrylic fibers having low heat resistance, a high processing temperature such as transfer printing using a disperse dye is required. In the processing, in addition to the problem that the flame-retardant acrylic fiber hardens and the texture deteriorates, there are problems such as a decrease in the sharpness of dyeing due to remarkable yellowing of the substrate and a large width of the fabric due to heat shrinkage. .

[0004] The present invention solves such a conventional problem,
In addition to preventing the curing and shrinkage of the flame-retardant acrylic fiber during transfer printing using a disperse dye, transfer printing with high commercial value as a whole fabric has excellent texture, excellent color development and light fastness. Another object of the present invention is to provide a flame-retardant composite fabric.

[0005]

The object of the present invention is to provide a composite fabric composed of at least 50% of flame-retardant fibers mainly composed of flame-retardant acrylic fibers and not more than 50% of polyester fibers by using a disperse dye in advance. The transfer paper on which
The problem is solved by a transfer printing method for a flame-retardant composite fabric, which comprises heat-treating at a temperature of 140 to 180 ° C. under a reduced pressure of 3 kPa or less.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The flame-retardant acrylic fiber used in the present invention comprises acrylonitrile as a main component and copolymerized with vinylidene chloride and / or vinyl chloride, or
These polymers are mixed, and if necessary, an antimony compound such as antimony trioxide or antimony pentoxide is added to make the flammable acrylic fiber flame-retardant.Specific examples include Super Balzer (Registered trademark of flame-retardant acrylic fiber manufactured by Mitsubishi Rayon Co., Ltd.), Kanecaron and Protex (registered trademark of flame-retardant acrylic fiber manufactured by Kanebuchi Chemical Industry Co., Ltd.), Rufunen (registered flame-retardant acrylic fiber manufactured by Kanebo Co., Ltd.) Trademark), Exlan W (product number of flame-retardant acrylic fiber manufactured by Nippon Exlan Industrial Co., Ltd.) and the like. These are preferably used alone as flame-retardant fibers, but may be used by blending cellulosic fibers, polyvinyl alcohol-based fibers or the like as long as the flame retardancy is not impaired. Specific examples of such a flame-retardant fiber include composite yarn in which cotton is mixed with Protex, Kanecaron STP, and the like.

On the other hand, the polyester fiber is not particularly limited as long as it has a good dyeing property with respect to the disperse dye.

[0008] Further, as the composite fabric, a flame-retardant acrylic spun yarn or a flame-retardant acrylic fiber of 50% or more and a cellulose fiber and / or a polyvinyl alcohol fiber 5
A cross-knitted fabric of a flame-retardant composite yarn blended with 0% or less and a polyester filament yarn or a polyester spun yarn is preferably used. In particular, a flame-retardant acrylic spun yarn for a weft and a polyester filament yarn for a warp are used. The mixed fabric used is excellent in dimensional stability, gloss and the like, and is useful as a composite fabric having a wide range of use. The fineness of the yarn used is not particularly limited as long as it is appropriately selected.

In the composite fabric, the content of the flame-retardant acrylic fiber or the flame-retardant fiber mainly composed of the flame-retardant acrylic fiber is usually required to be 50% or more, and if it is less than 50%, it is sufficient as the flame-retardant fabric. Function cannot be exhibited.

[0010] Transfer printing is performed by laminating a transfer paper on which a pattern has been drawn using a disperse dye on the composite fabric and heat-treating the composite fabric. The pressure is set to 13 kPa or less, and the temperature is set to 140 to 180 ° C. is necessary. Pressure 1
If the pressure exceeds 3 kPa or the temperature is lower than 140 ° C., the dye is less sublimated, the transfer efficiency is reduced, the color developability is reduced, and the light fastness of the dyed fabric is also reduced. On the other hand, when the temperature exceeds 180 ° C., the flame-retardant acrylic fiber is hardened, the texture is deteriorated, and yellowing and widthening of the fabric occur, and the dyeing clarity, dimensional stability, etc. decrease. The above processing conditions that can be most effectively and stably adopted for various objects of weaving and knitting structure of the flame-retardant fabric to be transferred and printed are as follows: a pressure of 4 to 8 kPa and a temperature of 150 to 175 ° C It is.

As the disperse dye, an ordinary disperse dye used for transfer printing of polyester fiber is used as it is.

EXAMPLES The present invention will be described in more detail with reference to the following examples. In the examples and comparative examples, the color development of the pattern of the dyed product was evaluated visually, and the evaluation of the texture was the most direct handling. Tested. The dimensional stability was measured by actually measuring the width of the fabric before and after the treatment, and the light fastness was evaluated according to the method described in JIS L0842.
