Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial Field of Application) The present invention relates to a method for manufacturing a tufted body for mops.

(Prior art) Conventionally, as a method for producing a tufted body for motsupu, a twisted string was twisted, and while the twisted string was meandering in a zigzag pattern, both ends and the middle part of the string were knitted with separate presser threads. After that, some of the presser yarns are left and other presser yarns are unraveled, and the twisted string is made to twist by itself using a strong twisting torque (Japanese Patent Laid-Open No. 60-188125
No. 2) has been proposed. In addition, a part of the presser thread is made of water-soluble fiber and the presser thread is dissolved in water to release the restraint of the twisted string (Japanese Patent Laid-Open No.
60-188127) has been proposed.

(Problems to be Solved by the Invention) Therefore, in both cases, it is very troublesome to remove the presser yarn used when forming the meandering band, reducing work efficiency and causing the yarn to unravel or dissolve. There is a problem in that the cost is high because the presser thread is used which is unnecessary.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention constitutes the string 3 by subjecting 7 to 20 fine-count cotton or cotton blend yarns to a strong twist, The knitting machine 1 takes 1 to 3 strings 3 as wefts and reciprocates them within a predetermined knitting width L, and at both ends of the knitting width L there are discarded needles 8 for locking the wefts.
9 is provided, and by reciprocating these alternately, the weft is locked to the waste needles 9, 8 on the opposite side, and then the waste needles 8, 9 are made to release the lock, and after the release, the weft yarn itself is twisted. At the same time as twisting the weft yarns of the adjacent reciprocating portions by
The weft yarn was knitted with stop yarn 11 to prevent twisting in more than one place.

(Function) When the weft yarn is reciprocated by the knitting machine and is stopped by the needles provided at both ends of the knitting width, it is knitted by the stopping yarn at the middle part of the knitting width, and the adjacent reciprocating weft yarn is stopped. The waste needle releases the weft thread. After unraveling, the weft yarns in the adjacent reciprocating portions are twisted together by the twisting of the weft yarns themselves, and work such as unraveling is omitted, improving work efficiency, as well as eliminating the need for stop yarns other than twist stoppers, reducing manufacturing costs. is reduced.

(Example) Hereinafter, an example embodying this invention will be described in the first to
Figure 4 will be explained.

FIG. 1 shows an outline of a knitting machine 1. The cord 3 wound around the weft bobbin 2 is supported by guide rods 4 and 5, and is reciprocated within a predetermined knitting width L as a weft through a weft guide member 6. The string 3 is constructed by strongly twisting 7 to 20 fine-count cotton or cotton blend yarns. The thickness of the thread is preferably 4 to 20, and the twist is preferably 2 to 22 turns/inch. In this example, 2 to 5 times /
The string body 3 is made up of 10 threads twisted to a length of 1 inch.

At both left and right ends of the knitting width L, waste needles 8 and 9 for temporarily locking the cord body 3 are provided so as to be able to move vertically and reciprocally in a straight line. body 3
After being locked, the cords 3 are reciprocated alternately to release the lock.

On the other hand, the retaining thread 11 as a warp wound around the warp bobbin 10 is supported by guide rods 12 and 13,
It is inserted into the thread guide 14. The retaining thread 11 is then supplied to the mop tuft 7 via a pair of knitting needles 15 located above the middle part of the knitting width L.

Next, the knitting process of the tufted body 7 for motsupu is shown in Fig. 2a~
f will be explained.

As shown in FIG.
The hook 15a is engaged with the hook 15a. Next, as shown in FIG. 2B, when the right hand needle 9 is moved upward and the cord 3 is engaged with it, the knitting needle 15 is moved forward and pulled out. At the same time, the thread guide 14 is moved upward and to the right, as shown in FIG.
spans a. Subsequently, the thread guide 14 is moved down as shown in FIG.
It is dropped within 5a.

Next, the knitting needles 15 are moved back as shown in FIGS. loop 11
The twist is stopped within b. At this time, the left hand 8 is moved down to release the left cord 3, and the adjacent reciprocating portions of the cord 3 are twisted together by their own twisting.

Thereafter, the same process is repeated, and the mop tuft 7 shown in FIG. 3 is continuously knitted using the retaining thread 11.

Then, as shown in FIG. 4a, the motu tufted body 7 knitted as described above is sewn with threads 18a to 18c.
At the same time, a bag cloth 17 is sewn onto the upper surface of the base cloth 16 to form a mop 19.

Now, in this embodiment, after the weft is locked with the waste needles 9, 8 on the opposite side, the waste needles 8, 9 are made to release the lock, and after the release, the adjacent reciprocating portion is moved by the twist of the weft itself. In addition to twisting the weft threads together, the threads 11 are simultaneously knitted at one or more locations in the middle of the needles 8 and 9 to prevent twisting.Compared to the conventional manufacturing method, the unraveling work is omitted and work efficiency is improved. In addition, it is possible to reduce the manufacturing cost by eliminating the need to use threads other than twist stoppers.

In addition, in this embodiment, the cotton or cotton blend yarn constituting the cord 3 is twisted at a rate of 2 to 5 times per inch, so each yarn of the twisted cord 3 is spaced apart from each other at an appropriate distance. The function as a mop formed by the tufted body 7 is excellent.

In the above embodiment, the waste needles 8 and 9 were provided so as to be able to reciprocate up and down in a straight line, but the waste needles 8 and 9 were arranged in a horizontal state perpendicular to the string 3 that reciprocated and could be moved back and forth. The cord 3 may be locked or unlocked by being provided so as to be movable or swingable within a plane.

Further, in the above embodiment, the motu tufted body 7 was produced by knitting with two stop threads 11 on the right side of the knitting width L, but the number of stop threads 11 can be increased or decreased, or the stop position can be set arbitrarily. good.

Furthermore, in the above embodiment, the mop tuft 7 was formed by taking one string 3, but two or three strings were used.
It may also be formed by cutting.

Effects of the Invention As detailed above, according to the present invention, compared to conventional manufacturing methods, it is possible to improve work efficiency by omitting the work of unraveling the stopper threads, and also to omit the use of stopper threads other than twist stoppers. It has an excellent effect of reducing manufacturing costs.
