Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on, for example, French Patent No. 1223330 and
No. 585119 relates to a natural summer dyeing method that overuses Kochi's transfer summer dyeing method, which was applied in the Meiden Hyo.

Silk has no affinity for the disperse dyes used in transfer dyeing and has no bath-resolving power, so it was thought that rope could not be dyed using transfer dyeing. In order to make this 6J efficient,
% Shelf 53-106883 is a grafted #4 fabric, i.e. styrene or other vinyl! - A silk fiber graft-polymerized with - was used. However, this graft polymerization requires a preliminary formation of the yarn, which presupposes the presence of a chemical reaction and a chemical catalyst, and is therefore quite a third-party method.

Another method for converting silk to 4 summer dyeing is described in the magazine 1#r Rutai (Aortas 22. Published December 1980, No. 33-37) JK. Acylation. This is a rather complex and expensive process.

A simpler preliminary treatment is proposed in JP-A-53-78386. I#4 fabric is S-contained with polyhydric alcohol 10-1001i having a boiling point higher than 140°C. The ropes formed in this way can be transferred and dyed using Tenshi paper that carries the ``Hanawaki'' Brassaceae.

It is stated in this publication that disperse dyes can also be used in addition to dyes. The main drawback of the method identified and described in this bulletin is that the dye does not penetrate into the silk fabric, resulting in completely different color tones between the outer layer and the layer side of the fabric. In addition, the summer brass material obtained by this method has very low resistance to oxidation.

One object of the present invention is to provide a simple method for photoprinting rope.

Another purpose of this book is to provide a dyeing method for offal that makes the color tone of S textiles almost the same as that of Ki.

Another object of the present invention is to provide a method for applying the transfer summer dyeing method to silk fabrics in an infant manner without performing any chemical reaction on the silk yarn or the dye.

Another objective of Motoya is to provide an economical method of dyeing rope without depriving the rope of its original texture, luster or other physical properties.

Other objects will become apparent from the description and examples below.

In the present invention, the silk foam containing 10 to 30 ringing agents has the following formula (wherein, alkyl is an alkyl group having 1 to 4 pseudowood atoms, and % is a methyl group, an ethyl group, and an isopropyl group). (wherein R is an ice 1g atom or a phenyl group, and C is a nonionic substituent that makes the molecular weight of the dye 200-300) and the formula ONM-Z [wherein, is a hydrogen atom, a hydroxyl group or a group Mu-R1 (where R1 is a lower alkyl group such as a methyl, ethyl or isopropyl group), and Y is
In the case of atoms, it is R1 and 4-, and! When is a group 1M-R1, it is a hydrogen atom and! is a hydrogen atom if X is a hydrogen atom or a hydroxyl group, and in other cases a group M
l! -R1] and heated to a temperature of 160 to 210°C for 20 to 60 seconds.

Typical examples of dyes represented by Ota) include 4-tolylazo-3-methyl-5-pyrazolone, 1-phenyl-
3-Methyl-4-phenylazo-5-hyrafH-n and 1-phenyl-3-methyl-4-(m-)lyraf)-
Dyes of the formula 0, including 5-virazolo/, include in particular 1-a, 2-methylanthraquinone, 1-
Amino-2-trifluoroethoxy-4-hydroxyanthraquinone, 1-akino-2-chlor or bromo-
Examples include 4-hydroxyanthraquinone and 1,4-diisopropylannoanthraquinone.

All of these dyes are known and can be made by known methods.

In Honkamei, it has a shorishi effect and is preferably heated to 150℃.
Pre-treating the silk with a chemical auxiliary having a boiling point of at least 10% or more, such as a polyhydric alcohol or its casting conductor or a plain bath or an aqueous dispersion thereof.
After being impregnated with water or dispersion containing preferably 15 to 30 parts by weight and squeezed through a squeeze wheel of 50 to 100 parts, the product may be subjected to intermediate drying. The temperature of intermediate drying is %
It depends on the shadow preparation used, but in general, from 120°C, glycol such as 4-lyethylene glycol with an average molecular weight of 200 to 4,000, polyzolopylene glycol with an average molecular weight of 400 to 5,000, or polyethylene glycol/boria with a basis average molecular weight of 400 to 5,000 is used. Lenglycol block copolymer: 1-butoxyethoxypropanol, polyhydric alcohol examples: Evergreen phosphorus, trimethylolpropane, addition product of polyhydric alcohol and acetyl oxide; addition of polyhydric alcohol and dichton Products.Among these, preferred are polyalkylene/IJcol filt hapolyethylene glycol.
&/(average molecular weight 250-1000), polypropylene 1 recall (average molecular weight 250-1000), polyethylene, and glycol ester.

According to this method, the pretreated product is placed under or on top of a transfer sheet that has been dyed in advance with a summer dyeing ink containing the above-mentioned valvular disperse dye, and is heated (pressurized while stacked) to produce a valvular disperse dye. The dye is incorporated into the textile product. Since the pre-treated auxiliary agent cannot be removed by Jl distillation, it is a boiling point auxiliary agent, so 11k is a commonly used method for dye preparation that fixes the dye on the assembly.
Illll or coating methods can also be used.

The following polyalcohols or their # conductors can be mentioned as I# preparations for @ used in this study: Alkylene glycol examples: Evaethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, v71'10 pyrene Glycol, tripropylene glycol, butanediol, bentanediol, hexylene glycol or octylene glycol; alkylene glycol and diether examples: ethylene glycol methyl ether, ethylene glycol monoethyl ether, $7 ethylene glycol Tyl ether, diethylene glycol dimethyl ether, diethylene glycol dimethyl ether, diethylene glycol dimethyl ether; alkylene dalycols and diesters such as ethylene glycol monoacetate, ethylene glycol zoacetate: To stabilize the polyflukylene, pretreatment aids are added by washing with water after transfer. It is desirable to remove it.

As a transfer sheet, a temporary support such as paper or a film is coated with the above-mentioned valve disperse dyes and candy mixtures (e.g. evaporative methylcellulose, ethylcellulose, hydroxyglobil cellulose, hydroxyethylcellulose, polyC-nylpyrrolidone, gelatin, polyvinyl alcohol). Any known sheet having a T-dye pattern dyed with an ink containing polyacrylic ester (acrylic ester or methacrylic ester) can be used. These transfer sheets and their manufacture are readily available. Since it is well known in the Qin world, no further explanation seems necessary.

The transfer itself is 160-210°C, preferably 180-1
9 parts at a temperature of 1°C for 20-60 seconds, preferably 30-50
It takes place in seconds. Transfer is performed at the lowest possible temperature within the above-mentioned l1lS, or at an elevated temperature of 160 to 210°C.
Yellowing of the rope can be prevented by using transfer paper coated with an optical brightener. This paper also describes the method for making transfer sheets therefrom.

After transfer, the transfer paper can be desilted and then the strip can be rinsed to remove the shadow formulation and dried.

The dyed silk can also be post-layered in a conventional manner to impart stretch, luster and texture to the silk fabric. These treatments are generally applied to silk fabrics to increase their commercial value.

Fabrics dyed in this way have the same or substantial K on both sides.
It shows 11l color tones.

According to the present invention, silk products can be dyed.

It is also possible to dye products made of silk and synthetic or semi-synthetic fibers in the same uniform color in the fine parts and in the synthetic or biosynthetic parts. Furthermore, one of the importance of using the method of the present invention is that good results can be obtained even when this method is applied to fabrics that cannot generally be dyed due to their coarse texture, such as lawn or dye. That's what it means.

By using the method of the present invention, the dyed royal products and delicate trees with sharp end contours are displayed to meet the expectations of consumers.

The present invention will be described in more detail with reference to the following examples.

Example @ Fabric is made of polyethylene glycol (molecular weight 600) 3
0 Nobunsui II! ) Impregnated into the chain, dried to 100 strands and dried at 70°C for 10 minutes. On the other hand, using a gravure printing press, add isonolonol/ethanol (1
:1) By dispersing 10 parts of Kl-azuno 2-chloroanthraquinone and 6s of ethyl cellulose in the mixed bath medium of 1), gravure dyeing paper sheet is dyed with gait and danari dyeing ink, dried and transferred. Manufacture dyed sheets.

The silk aggregated with polyethylene glycol (molecule t3uO) was layered with a transfer sheet, and then placed in a 1Klless machine.
Heat it at 00°C for 30 seconds and press it at a pressure of 1.

The silk thus dyed is immersed in water, reduced to a print rate of 70 degrees, and tumbled at 100° C. for 4 minutes.

The resulting fabric exhibits eight colored horizontal bars with the same color tone on both sides.

In the example above, the use of 1,4-cyinobutetrabylaminoanthraquinone provides background color strength.

In this method, 1-phenyl-4-phenylazo-3-methyl-5-pyrazolone was used as the yellow dye, 4-hydroxyanthraquinone in 1-quinol-2-trifluoroethane was used as the red dye, and 1-hydroxyanthraquinone was used as the blue dye. ．．
If 4-diisopropylanthraquinone is used, multicolor conversion power can be obtained.
