Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a method for printing and dyeing knit products.

[Fr view for fi] The production of patterned products or semi-finished products has conventionally been carried out as follows.

The first method is to dye the fabric and knit or weave it into the desired pattern.

The second method is to perform printing in eight desired ways after creating a product or semi-finished product.

The present invention relates to a method of: jS2.

Printing here refers to printing and other operations.

It is pattern dyeing.

The printing process is a printing process in which one color glue is placed on the fabric, a fixing process to dye and fix the dye in the printed color glue after printing, and a printing process in which the dyestuff in the printed color paste is dyed and fixed. It consists of a washing process to remove the dye.

The fixation process is carried out by so-called gonorrhea, i.e. (
2)] Once dried after printing, the dye in the paste is still in an undyed state, so in order to cause dyeing, it is heated using a wooden folding screen, and this is steam heat.
However, although this type of conventional printing method has been applied to fabrics, it has not been applied to knit products. This is because it will be damaged.

(Objective of the invention) 7. The invention aims to provide a method for printing and dyeing knit products that can produce knit products that are useful in combination.
i-target.

[Summary of the invention] Item 1
After printing the Hokuryoku color glue, the step of 2.) placing a sponge on the printed surface of the product and placing it in a steamer and steaming it at a predetermined temperature with supersaturated steam at one pressure: a/A By a printing and dyeing method for knitted products, which is characterized by a process of washing with water after heating, I! will be accomplished.

The structure and elements of the present invention will be explained below.

The first step of the present invention is a step of printing colored glue on the surface of the knit product.

This step Y also includes a drying process after printing the colored paste.

Color paste printing methods are broadly divided into those using a printing plate (letterpress method, intaglio method, stencil method,
The present invention includes both methods (manual printing) and spray printing (spray printing).

In addition, two-phase printing, that is, the ingredients in the color paste and the dye,
The chemical auxiliaries that set the chemical conditions for dyeing are separated into two. First, only the dye is printed and dried, and then the chemical auxiliaries necessary for dyeing are added to it by insects. The concept also includes printing means applied by ply printing or padding.

Color paste is a paste for direct printing that is made by adding all the chemicals necessary for dyeing, such as dyes and penetrants, to the printing paste, or, in the case of two-phase printing mentioned above, only dyes. It also means a mixture of.

Knit is also known as stockinette or jersey, and refers to all knitted fabrics that are knitted by machine or by hand.To be sure, the basic structure of knit is shown as horizontal knit (flat knit, rubber knit, purl knit), vertical knit ( The present invention covers all types of knits, including ``Nunkurutenha&i'', single cord edition, and single/tied edition.

Examples of knit fabric fibers include wool, animal hair (syrup), cotton, cotton, rayon, and blended fabrics.

Further, in the case of a knit product, in addition to a complete product shape, it may be a rough yarn-dyed product, including a half-finished T8 product such as only sleeves, for example.

The :fS2 process of the present invention is performed after printing the colored glue.
In this process, a sponge is placed on the printed surface of the product, placed in a steamer, and heated at a predetermined temperature with supersaturated steam at one atmosphere.

This process is for fixing the dye 1 on the surface of the product using steam.

The sponge and knitted product can also be layered alternately in multiple layers. Furthermore, it is convenient to arrange the device within the steamer horizontally with respect to the ground.

Any type of sponge can be used as long as it can withstand the specified li and once. For example, a latte 7x sponge can be used.

The steamer may be one that is conventionally known, that is, the product is stored in a processing chamber filled with steam,
IK style or non-J! It is a mechanical device that reacts in one direction.

The atmospheric pressure inside the steamer is 1 atm.

The temperature of the non-air varies depending on the type of fiber.

Table 1 shows the steam temperature along with the steaming time.

The saturated wind in Table 1 is l! ! It changes with the melon, but 1.1
Table 2 shows the relationship between degree and saturation 1λ.

Table 2: If the saturation level is high, water droplets will increase, the pattern will be washed away, and the adhesion will be poor.

On the other hand, if the degree of saturation is low (if the temperature is high), the J material will be damaged and the soft wet feeling will be lost.

The uninvented third step is a step of washing with water.

Before this process, a color fixing agent (fixing agent) is applied.
In other words, it is a chemical used as a post-dyeing treatment agent mainly for the purpose of improving the fastness of dyed products such as direct dyes, 1-reactive dyes, and acid dyes. Cationic organic compounds that grow poorly soluble chelate compounds are mainly used.

For example, Closol SS and Acitol Super (Hitachi Chemical FF15m) may be used for wool products, and RH505 (manufactured by Toyobo Co., Ltd.), Danfix, etc. may be used as a color fixing agent for cellulose-based material products.

[Embodiments of the invention] The present invention will be explained in detail below.

It should be noted that, as a matter of course, the scope of the present invention is not limited to the following examples.

(First Example) - A knitted product made of 40% angora, 45% wool, and 15% nylon was pre-dyed in pink, and after being spray-printed with color paste, it was steamed in a steamer. The temperature of steaming is 125-130°C and the time is 50 minutes. Inside the steamer, knit products and latex sponge were alternately stacked in multiple layers.

After steaming, it was washed with water.

The final product thus produced is shown in FIG.

No color pollution.

Table 3 shows the fastness test results.

Table 3 Printing methods are divided into two categories depending on the printing method: those that use a printing plate (letterpress method, intaglio printing method, stencil printing method, mohan printing method), and those that do not use a printing plate (handwriting, spray printing). It can be divided into

However, in the former case, the design has to be standardized, and the use of multiple colors, blurring, fading, and bleeding patterns are not necessarily free. Not being able to adequately meet needs.

However, in this example, printing is performed without using a printing plate, so it is possible to freely use multiple colors, blur, blur, and smudge patterns, making it possible to fully meet the diversifying needs of the fashion world. .
