Abstract

The present invention provides a preparation method of wavy segment dyed yarn. The preparation method includes the following: step 1, fabric knitting, which utilizes a weft knitting machine to form a fabric by interlocking the consecutive rows of loops formed from a straight yarn through knitting motion; step 2, cloth scouring, which scours out and boiling the fabric; step 3, fabric segment dyeing, which segment-dyes the fabric along the warp direction, having the fabric segment-dyed with colored straight stripes in various colors; and step 4, fabric withdrawing, which utilizes a drum yarn recoverer to withdraw the fabric, recovering a wavy segment dyed yarn therefrom. Thereby, the aforementioned steps of preparation method not only improves the yield, but also enhances the production efficiency of the segment dyed yarns, while enriching the yarn's color at the same time, and providing superior elastic resilience. The achieved functions and effects are beyond the ability of current segment dyeing technology.

Description

Method and structure for wavy segment dyed yarn

The invention relates to the technical field of textile segment dyeing, in particular to a method for producing a wavy segment dyed yarn.

Traditionally, the woven fabrics made of yarns are usually monochromatic because they are limited by the dyeing technique of the yarns. Therefore, the woven fabrics are monotonous and uninspired, so that the manufacturer can develop a patent document such as a patent document. 1 is a yarn making method and a composition structure. The yarn is first made into a tubular structure, wound into a yarn roll, and then the yarn roll is subjected to segment dyeing to have a spaced color, and then the tubular yarn is used. The wire drawing is reduced to a single yarn, so that the single yarn has a different color interval of the long section, and the weaving is finished as a finished fabric with parallel lines to change the problem that the conventional yarn is monochromatic.

However, the above yarn manufacturing method and composition structure solve the problem that the conventional yarn is monochromatic, but the following problems still exist:

1. The above yarn making method can only produce one segment dyed yarn at a time, so the output and production efficiency are extremely low.

2. The above yarn making method applies segment dyeing in a lateral direction, so that when the yarn is drawn from the coil, the interval of the color section of the yarn is longer, so that the color change is less.

3. The yarn making method described above, when the yarn is drawn from the coil, the yarn is reduced to a parallel line, so the elasticity of the yarn is poor, and the yarn is easily broken when the fabric is woven to cause yarn unwinding.

In view of this, how to solve the above problems, develop a good elasticity, color The method and structure of the wavy segment dyed yarn with many changes and high production efficiency have become the ideas and research subjects of the creators of the present invention.

More preferably, after the cloth is steamed (C1), a step of drying the cloth (C2) is further added, in which the steamed and washed cloth (2) is dried.

In order to solve the foregoing problems and achieve the object of the present invention, the technical means of the present invention is structured as a wavy section dyed yarn, characterized by comprising: a yarn dyed in a wavy section as claimed in claim 1 The wavy segment dyed yarn (3) produced by the method of the present invention; the wavy segment dyed yarn (3), which is formed by connecting a plurality of curved segments (31) of different colors, the curved segment (31) The top end and the bottom end each have a curved line segment (311) which is alternately alternately and mutually offset, and the curved line segments (311) are connected by a connecting portion (312), and the curved line segment (311) is utilized. Cooperating with the connecting section (312), the wavy section dyed yarn (3) has a good elastic restoring force.

According to the implementation of the above technical means, the functions, functions and effects that can be obtained by the present invention are as follows:

First point: In the present invention, the application of the method for producing the wavy segment dyeing yarn can produce a plurality of wavy segment dyed yarns (3) at one time, which greatly increases the overall yield and improves the overall The production efficiency, which is the function and effect that can not be achieved in the technical field of textile segment dyeing.

The second point: the method for preparing the wavy segment dyed yarn of the present invention can be applied to both the circular knitting machine and the flat horizontal knitting machine, so that the application scope of the invention is wider, and the operator is not limited by the equipment. Production.

The third point: using the method for producing the wavy segment dyed yarn of the present invention, the wavy segment dyed yarn (3) after segment dyeing has more types of colors, and the boundaries between the respective colors are distinct, and between the colors The spacing can also be controlled by the operator's own needs, long and short, and the elastic recovery force of the wavy segment dyed yarn (3) is also better than the existing segment dyed yarn, so the yarn is dyed by the wavy segment (3) The woven fabric can have better elasticity.
