Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application The present invention relates to a tufted cloth in which loop piles are formed on the surface of the base cloth.

(b) Conventional technology Tufted fabrics with loop piles formed on the base fabric surface are widely used for carpets, etc.; Unless the pile has a structure in which threads are intertwined like in knitted fabrics, there is a problem in that when the loop is stretched, the pile threads easily pull out from the base fabric. In order to prevent this slipping off, back glue is applied, but as the glue ages, it tends to come off easily, and it cannot be said that prevention of the slipping off of the pile threads is perfect.

(c) Problems to be solved by the invention The present invention fundamentally modifies the structure of the loop pile of the conventional tufting cloth, and attempts to solve problems such as the pulling out of the pile threads. .

2) Means for Solving the Problems Explained with reference to illustrative drawings, the present invention, as shown in FIG. The motion and the forward and backward movement of the looper 5 that forms the pile yarn into a loop 4 form a loop pile 6 on the surface of the base fabric. By continuously repeating the operation of inserting loop 3 to form the next loop (see especially figure 3), loop 4 is connected in a chain as shown in figures 1 and 2. The present invention relates to a tufted cloth 7 characterized in that a loop pile 6 made of chain loops is formed on the surface of the base cloth.

Each of the figures A, B, C, D, and E in FIG. 3 sequentially shows the interlocking operation of the needle and the looper when forming the loop pile of the present invention.

Figure A shows the initial position of the needle ascent and the final retracted position of the looper. Figure B shows the intermediate position of the needle ascent and intermediate position of the looper forward. Figure 6 shows the initial lower position of the needle and the final forward position of the looper. Figure D shows the needle lowered position. The intermediate position and the looper retraction initial position are shown, and the diagram E shows the needle lowering final position and the looper retraction intermediate position. Among the above, figure D shows how the needle 3 is inserted into the loop 4 formed by the looper 5.

In the present invention, for example, as shown in FIGS. 4 and 5,
A looper 5 is used in which plates 8 and 9 of the acting part of the looper are divided into two parts and have a bulge, and a gap 10 is provided in the bulge part. The needle 3 inserted through the loop 4 of the third drawing is inserted into the gap 10 of the looper 5. When the looper having the above structure is used, the bulge of the plates 8 and 9 of the action section widens the width of the loop 4, making it easier to insert the needle, and since the plates 8 and 9 of the action section are divided into two parts, the needle can be easily inserted. , the looper 5 can be moved backward without being hindered by the needle inserted into the gap 10.

(E)) Function The present invention, when forming a pile yarn into a loop by the linked operation of a needle and a looper, inserts the needle into the formed loop to form the next loop, and continuously performs this operation. Since this is repeated repeatedly, the loop pile formed on the base fabric surface becomes a chain loop in which loops are connected in a chain.

(f) Effects of the Invention In the product of the present invention, the loop pile forms a chain loop, and each loop is sewn to the base fabric in such a manner that it presses down one neighboring loop and is held down by the other neighboring loop. Unlike conventional tufted fabrics, the pile threads do not come off. Therefore, it can be used for various purposes without having to glue the back of the container to prevent it from coming off.

In addition, the product of the present invention has a suppressed loop, which improves quality.
It has a stable texture, uses less pile yarn, and has high productivity, so it can be manufactured at a low price, and because it has a smaller volume than conventional pile products, it has the effect of reducing transportation and other distribution costs.

The product of the present invention has a wide range of applications, and can be used not only for general drinks but also for wall covering materials, upholstery materials, electric carpets, automobile seat materials, etc.

Claims (1)

[Claims] 1. In a tufting fabric in which a loop pile is formed on the surface of the base fabric by the coordination of the vertical movement of a needle that carries pile yarn and pierces the base fabric and the forward and backward movement of a looper that forms the pile yarn into a loop, By continuously repeating the operation of inserting a needle into a loop formed by a looper to form the next loop, a loop pile consisting of chain loops in which loops are connected in a chain is created. A tufted cloth characterized by being formed on the base fabric surface.
