Description

Dyeing method for yarn

The present invention relates to a partial dyeing method of the yarn, and more particularly, in the dyeing process of coloring various colors on the intrinsic color of the yarn prepared through chemical fibers and natural fibers, the color partially to the yarns weaved before weaving process It relates to a partial dyeing method of the yarn to express.

In general, dyeing is a work process that expresses various colors by coloring various fibers or textile products (thread), and is classified into dyeing and printing according to the dyeing method.

The dyeing is to perform dyeing by precipitating the dye in a solution in which the dye is dissolved. Such dyeing is roughly a refining process for removing impurities contained in weaving or weaving, and bleaching and bleaching with bleach and acid solution. , Washing process, dyeing process to dye uniformly the same color in the salt bath filled with salt solution, washing process to remove dyes and chemicals remaining after soaking, dehydration process for washing and dehydration after washing, and drying process Immersion refers to a dyeing method that expresses the same color throughout a thread or fabric.

On the other hand, printing represents the required pattern by partially coloring the thread or fabric, especially the fabric, and is divided into mechanical printing and male printing according to the printing work method, and classified into dye printing and pigment printing according to the colorant used for printing. do.

The dye printing is selected for easy dyeing according to the material to be stained, and after stamping the fabric through a roller and a screen using a printing paste stirred by adding a dye and coloring agents to such dyes Complete by drying, steaming, and washing with water.

In addition, the pigment printing forms a printing paste with synthetic resin (initial condensate), solvent, water, etc. on the pigment, seals the printing paste on the fabric through a screen, and finishes it by washing with a high-temperature dry heat treatment. In addition, the pigment having undergone such a process is characterized by being firmly bonded to the fabric by the adhesion of a colorant or a synthetic resin having no affinity with the fabric.

As described above, printing, including dyeing, is to form a pattern of the same or specific shape on the whole of the woven fabric, including thread, and is a useful dyeing method for uniform and repetitive mass production.

Recently, however, partial color expression is required in whole fabrics rather than uniform color expressions of the same color such as dyeing or printing due to various inclinations of consumers. Partially dyed yarns were produced to create a completely new color and pattern after weaving.

However, for the partial dyeing of the yarn as described above, the situation is not activated due to problems such as the difficulty of the work process and the additional installation of the dyeing equipment.

Among them, the partial dyeing method of the conventional yarn is briefly described.

First, the yarn having various mechanical properties required for weaving was wound on a drum or the like, and then a salt solution or dye was sprayed onto the wound yarn by hand to achieve partial dyeing of the yarn.

The partial dyeing of the yarns as described above results in a reduction in dyeing quality, including dyeing stability due to partial dyeing by hand, as well as the quality of the fabric using the partially dyed yarn produced through the above process is also reduced simultaneously. He had a problem that caused his economic loss from his career.

Therefore, the present invention was created to solve the above problems by forming a knitted fabric through the knitting process using the yarn of the outer strand, and after dyeing through the printing on the knitted fabric, by dyeing the knitted fabric, only part of the dyeing treatment It is aimed at maximizing economic profits by producing high quality partial dyeing room and mass production by improving productivity.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

Figure 1 is a block diagram showing the working progress of the present invention the partial dyeing method of the yarn, Figure 2 is a simplified view showing the knitted fabric produced by the partial dyeing method of the present invention, Figure 3 is a partial dyeing of the present invention yarn Figure 4 is a simplified view showing the sea state of the knitted fabric produced by the method, it will be described together with a view showing the yarn produced through the partial dyeing method of the present invention yarn.

Partial dyeing method of the present invention yarn to achieve the above object is the processed yarn as shown in Figure 1, knitting process (10) → print dyeing (printing) process (20) → maritime process (30) → post process (40) )

The knitting process 10 should be knitted using a single strand that requires dyeing, in order to smooth the nautical properties in a knitted fabric state.

In addition, the print dyeing process 20 is performed through a general printing process, and as shown in FIG. 3, the same color may be sparse at regular intervals, or different colors may be cross-arranged to simultaneously express various shapes and colors.

The sea sand process 30 is a process for releasing the woven state of the printed knit fabric and reducing the yarn to its original shape. The sea sand process 30 is wound on a drum to be used for weaving, which is the next process at the same time as sea sand, and the wound partial dyeing yarn is required for weaving using After going through the post-process 40 to achieve the physical property requirements, the fabric is completed through various types of weaving process.

The partial dyeing method of the present invention yarn as described above will be described in detail through the examples of each process as follows.

Example

First process-knitting process 10;

It is a process of forming a knitted fabric having a certain standard through a knitting process by using natural or chemical chambers that have been given various mechanical properties through a weaving process and a later process.

In the knitting process, various types of knitting machines are used to form the knitted fabric 11, and such knitting machines are typically warp knitting machines, weaving knitting machines, circular knitting machines, and the like. This is to achieve the damage of the yarn and the improvement of workability through the smooth seas in the sea process.

2nd process-print dyeing process (printing; 20)

The yarn 12, which has undergone the first process 10, forms a knitted fabric 11 of a predetermined size as shown in FIG. 2, and partially prints and dyes the dyes and pigments of various colors through printing on the knitted fabric 11. It is a process. The print dyeing process 20 determines the shape of the yarn partially dyed through various types of print dyeing, such as simultaneously displaying margins at regular intervals using only the same color or expressing different colors by crossing each other.

In addition, it is natural that the knitted fabric 11 performing the print dyeing process 20 performs a dry heat, drying and washing process, which is a general printing process described above.

Third Process-Maritime Process (30)

The process for restoring the knitted fabric 11 in which the printing dyeing is completed to the initial yarn 12 state, when forming the knitted fabric 11 in the first step 10, it is necessary to knit with one strand of yarn. This is to perform the maritime process smoothly.

The seal 12, which is dismissed through the sea process 30, is wound around the drum 31 so that it can be used for a subsequent weaving operation through a constant winding tension at the same time as the sea to improve work efficiency and productivity. Make it work.

4th and Postprocesses (40)

When the change of the initial mechanical properties of the seal 12 undergoes each of the steps 1, 2, and 3 to form a suitable physical property for weaving, it is possible to enable smooth weaving through various treatments if necessary.

The partial dyeing chamber 12 generated through the partial dyeing method proceeds as described above, in which a single color and a margin or various colors coexist in one strand of yarn, as shown in FIG. 4.

It is possible to express various colors and patterns while using the same partial dyeing thread according to the weaving conditions by avoiding the color of the uniform dyeing in the conventional dyeing method and the same pattern in the printing.

When weaving through partial dyeing yarns, we use both partial dyeing yarns for warp and weft yarns, or weaving yarns using all dyed yarns and only weft yarns for partial dyeing yarns. Can be expressed.

As described above, the partial dyeing room, which is generated through the partial dyeing method of the yarn, can be produced more personally than the color and pattern expressed through dyeing and printing.

In addition, the partial dyeing method of the present invention can solve problems such as lowering of dyeing reliability and lowering of productivity of the conventional partial dyeing method.

Partial dyeing method of the yarn as described above is to perform a partial dyeing by printing on the knitted fabric formed through the knitting, excellent dyeing reliability, as well as quality improvement of fabric paper after weaving, and easy to dyeing work to achieve the cost saving effect according to productivity improvement Can be.

In addition, a separate additional dyeing facility for partial dyeing is unnecessary, and it is a useful invention that can reduce the economic burden by using existing knitting machines and dyeing facilities.
