Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a pile knitted fabric capable of simultaneously and easily manufacturing two pile knitted fabrics at a high speed with an ordinary double knitting machine.

2. Description of the Related Art Conventionally, a single pile knitted fabric is manufactured by using a sinker pile knitting machine provided with a cylinder needle and a sinker, and two yarns of a ground knitting yarn and a pile yarn are supplied per yarn feeder. It is knitted. The pile knitted fabric obtained with such a sinker pile knitting machine has both a pile surface and a sheeting surface.
It is one piece. When knitting with this sinker pile knitting machine, it is necessary to replace sinkers with different heights of sinker nose in order to change the length of the pile loop, and that work takes a long time, and furthermore, the height differs. The need to own a variety of sinkers is a factor that increases manufacturing costs. Furthermore, since the length of the pile loop depends on the height of the sinker nose, an arbitrary length cannot be obtained. . Also, a method of modifying a double knitting machine, using a special hookless needle in place of a dial needle, and making the hookless needle act as a sinker to produce a pile knitted fabric is often used. However, this method also requires an operation of replacing a hookless needle with a dial needle, and involves many cost-up factors such as provision of a hookless needle and a special knitting cam. further,
Because the dial needle that originally performs stitch formation is not used,
There are also production problems such as the knitting efficiency being halved.

Problems to be Solved by the Invention As described above, the conventional manufacturing method has problems in versatility, manufacturing cost, and the like.

The present invention solves such a problem, and an extremely high production efficiency capable of substantially knitting two pile knitted fabrics at the same time using an ordinary double knitting machine without a special device is obtained. It is an object of the present invention to provide a highly versatile manufacturing method which can arbitrarily obtain a pile loop length steplessly within a certain range.

Means for Solving the Problems In order to solve this problem, the present inventors can simultaneously obtain two pile knitted fabrics from a normal double knitting machine by skillfully utilizing the knitted fabric structure and the yarn characteristics. This has led to the present invention. That is, the present invention uses a knitting machine having a front needle for forming a stitch on the front side of a knitted fabric and a back needle for forming a stitch on the back side of the knitted fabric. A first step of forming a stitch of the active yarn, and at least one of a front needle or a back needle formed in the first step
A second step in which the pile yarn is stitch-formed by the alternate back needle or the front needle, and a stitch is formed in the ground knit yarn only by the back needle or the front needle, and no stitch is formed in the second step. A third step of stitch-forming a water-soluble yarn with a back needle or a front needle; and a pile of a back needle or a front needle stitch-formed in the third step with a front needle or a back needle not stitch-formed in the first step. A fourth step of forming a ground knitting yarn only with the front needle or the back needle at the same time as forming the yarn with the stitch;
The knitted fabric knitted in the first to fourth steps is treated with water or hot water to dissolve and remove the water-soluble yarn, and then the back knitted stitch is formed by the outer needle and the outer knitted portion formed by the outer needle. It is characterized in that the part is peeled off and divided into two sides.

Hereinafter, the method for producing a pile knitted fabric of the present invention will be described in detail.

First, in the present invention, a knitting machine provided with a front needle forming a front side stitch and a back needle forming a back side stitch, that is, a special knitting structure is set using a normal double knitting machine, and a water-soluble yarn is formed. Skillfully form stitches.

The ordinary double knitting machine according to the present invention is a double knitting machine represented by a circular knitting machine having a dial needle and a cylinder needle or a double needle bed type flat knitting machine having a front needle and a back needle. It is a knitting machine.

In the first step of knitting by the double knitting machine, a water-soluble yarn is stitch-formed with at least one alternate needle, a front needle or a back needle. In the knitting second step, the pile yarn serving as the pile stitch is supplied, the stitch is formed by the same front needle or back needle as the stitch formed in the first step, and the stitch is connected to the water-soluble yarn stitch and faced. A ground stitch is also formed with at least one alternate needle of a back needle or a front needle. Further, in the same process, it is necessary to run a ground knitting yarn different from the pile yarn to the back side of the front needle or the back needle and supply the yarn only to the back needle or the front needle to form a back knitting portion or a front side knitting portion. There is. The ground stitches formed by the ground stitches are aligned with the pile yarns to form the foundation of the knitted fabric, and correspond to the inner stitches of the sinker pile knitted fabric.

Since the water-soluble thread formed in the knitting first step is dissolved and removed in the subsequent processing, the pile thread-shaped stitch connected to this water-soluble thread-shaped stitch is disengaged and rises, and the pile is stood up. Change to a loop. At the same time, the bonding with the front or back side knitted fabric forming the stitches of the water-soluble thread is also released, so the separation between the front and back knitted parts is possible, and as a result, the separated portion has formed a pile loop. Single knit structure.

Next, in the third knitting step, a stitch is formed using a water-soluble yarn with a back needle or a front needle that has not been stitched in the second knitting step.

Further, in the fourth knitting step, using a pile yarn, both the back needle or the front needle in which the water-soluble yarn is stitched in the third knitting step and the front needle or the back needle in which the stitch is not formed in the first step. A stitch is formed by a needle, and at the same time, another ground knitting yarn is run to the back of the back needle or the front needle to feed only the front needle or the back needle, thereby forming the front or back ground knitted portion. The purpose of the stitch formation in the third and fourth steps is to obtain pile and to separate the front and back in the same manner, except that there is a difference between the front and back in the first and second steps. By repeating the first to fourth knitting steps as described above, the knitted fabric of the pile knitted fabric of the present invention before being piled can be obtained.

In the above-described method for producing a pile knitted fabric of the present invention, knitting for forming a stitch that is not connected to a water-soluble yarn between the knitting second step and the third step and between the knitting fourth step and the first step. Additional steps are acceptable. The water-soluble yarn used in the method of the present invention may be of any type as long as it can be easily dissolved by treatment with water or warm water, and for example, water-soluble vinylon is optimal. . On the other hand, the pile yarn and the ground knitting yarn are not particularly limited, and any yarn other than the water-soluble yarn can be appropriately used depending on the application.

Next, an embodiment of the method for manufacturing a pile knitted fabric of the present invention will be described with reference to the drawings.

Figure 1 is a knitting operation diagram for manufacturing a pile knitted fabric of the present invention, stitches form a water-soluble yarn Y ₁ by yarn feeder F ₁ in the cylinder long needle CL in conventional double knit circular knitting machine. And stitch-forming pile yarns Y ₂ by the yarn feeder F in ₂ in the yarn feeder F ₁ stitch-forming the cylinder minute hand CL and dialing long hand DL, and the land knitting yarn Y ₃ only dial minute hand DL stitches formed. Water-soluble yarn in the yarn feeder F ₃ in dialing short hand DS Article Y ₁
Was stitch-forming pile yarns Y by the yarn feeder dial hour hand DS that stitches formed at F ₄ in the yarn feeder F ₃ and cylinder hour hand CS

FIG. 2 is a schematic view of a cross-section of a knitted fabric knitted according to the knitting operation diagram of FIG. ₁ , in which stitches A ₁ and A ₂ formed by a water-soluble yarn are wale W ₂ of cylinder long needle CL and wale of dial short hand DS. W ₄
, Respectively.

Pile yarn stipulates wale W ₃ stitches B ₁ cylinder side connected with stitches A ₁ by a water-soluble yarn in the wales W ₂ of the (front) has stitches formed, further dial side (back side)
In forming a stitch D ₁ with stitches C ₁ by the ground knitting yarn, it is linked to a land stitch G ₁ of one course before. Also, ground stitches C ₁ , C ₂
The ground knitting yarn which forms the first and second surfaces does not constitute a single yarn on both the front and back surfaces, but each independently constitutes one of the front and back surfaces. On the other hand, the wales W ₁ of another pile yarn Article stitch B ₂ dial side connected with stitches A ₂ of the water-soluble yarn in the wales W ₄ of (back) has stitches formed by further cylinder side (front side) in forming a stitch D ₂ together with stitches C ₂ by the ground knitting yarn, it is linked to a land stitch G ₂ of one course before. The knitted fabric having such a structure has the same appearance as a normal double-sided knitted fabric at the time of knitting, and no pile structure is recognized. However, when the knitted fabric is treated with water or hot water to dissolve and remove the water-soluble yarn and give a peeling action, as shown in FIG. 3, the knitted fabric 1 on the cylinder side (front side) and the knitted fabric on the dial side (back side) are used. The structure changes to a structure divided into two parts. That is,
Linking stitch B ₁ by stitches A ₁ of the water-soluble yarn in the wales W ₂ of the cylinder side is dissolved is released, and separated from the cylinder side knitted fabric 1, so that the stitch B ₁ is deformed in the pile stitch P ₁ I do. Similarly, stitches B ₂ is separated from the dial side knitted fabric 2 for stitches A ₂ of the water-soluble yarn even wale W ₄ of the dial side is dissolved, changes in the pile stitch P _2.

Thus, the cylinder side knitted fabric 1 becomes a single pile knitted fabric composed of the ground stitch G ₂ , the stitch D ₂ of the pile yarn, the stitch C _{2 of} the ground knitting yarn, the pile stitch P ₂ , and the like. land 2, ground stitch G _1, stitches D ₁ by the pile yarns, the stitches C _1, and pile stitch P ₁ Single pile knitted fabric composed of such as by land knitting yarn.

The method for manufacturing a pile knitted fabric of the present invention can easily obtain two single pile knitted fabrics from one double knit as described above, so that high production efficiency is of course required, and special equipment is not required. It can be manufactured with a double knitting machine. Furthermore, in the case of circular knitting machines, it is possible to set a stepless pile loop length in a short time by changing the gap between the needle hook of the dial and cylinder, or adjusting the stitch length of the dial and cylinder. .

Next, as a method of dissolving the water-soluble yarn and separating the pile knitted fabric into two sheets, the front and back two sheets at the knitting end are respectively gripped, and the two sheets are mechanically pulled toward the knitting start direction. Separate so as to peel off, and wind up both knitted fabrics separately.

The pile knit fabric manufacturing method of the present invention, as described above, forms a stitch on a specific wale on the front and back of a stitch using water-soluble yarn, and forms a stitch on a front and back specific wale with another yarn. The main function of the knitting step is to carry out a knitting step, and a peeling step of dissolving and removing the water-soluble yarn in the knitted fabric obtained in the knitting step and separating the yarn into two sheets. In other words, in the double knit structure, the base knitted portion where the stitches are separately formed on the front and back and the double-sided knitted portion where the stitches are formed on both the front and back are used as main elements, and the water-soluble yarn connecting the front and back stitches is dissolved. In this way, the material is transformed into a separable state, and the double-sided knitted portion is separated from the front and back tissues, whereby the separated portion is embodied as a pile loop. Therefore, the pile loop length is increased by increasing the distance between the needle beds (needle shuttles) forming the front and back stitches. Further, even if the stitch length of the stitch connected to the stitch of the water-soluble yarn is increased, the pile loop length can be increased.

Examples Hereinafter, the method of the present invention will be specifically described based on examples.

Commercially available dial cylinder type double knitting machine (20
Using G), three examples shown in Table 1 were knitted according to the knitting operation diagram of FIG. The obtained knitted fabric was refined with hot water at 90 ° C. for 15 minutes to dissolve and remove the water-soluble yarn. Thereafter, the front and back sides were peeled off from the end of the knitting, separated into two pieces, and finally dyed and finished by a conventional method. As a result, a single pile knitted fabric having a uniform pile length and excellent quality could be obtained.

Effect of the Invention As described above, the pile knitted fabric manufacturing method of the present invention is a technique that skillfully combines yarn characteristics and a special knitting structure using a normal double knitting machine, and is different from a water-soluble yarn. It has a step of forming stitches on the specific wale of the yarn, and a step of dissolving the water-soluble yarn in a usual refining step, and separating and splitting the front and back two sheets. Therefore, the knitting function of the knitting machine is fully utilized, high productivity to obtain two single pile knitted fabrics at a time, and the pile length can be continuously and continuously reduced within a certain range. It is excellent in versatility such that it can be set at a low speed, and has economic advantages such that no special device is required for the knitting machine.
