Abstract

PURPOSE:To provide a clear pattern by overtufting a base material once tufted. CONSTITUTION:A primary base cloth 1 is tufted to form cut pile or primary pile 2 of loop and provide a base material 3 of a patterned carpet. This pile system is of relatively thin (15-7 count) spun yarn such as that of nylon, acryl, etc., and impregnated with an antistain oil agent such as spindle oil. A secondary pile 12 is overtufted on the base material of this pile cloth to form any pattern 19. A lining material 20 is formed by NBR, etc. Thus, the primary pile of relatively thin spun yarn improves remarkably the dust arresting performance by the synergic effect with impregnation of the antistain oil agent and further provides the clear pattern by forming the secondary pile with the overtufting.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a dust control mat with a distinct pattern.

(Prior art and problems) Conventionally, as a method of forming patterns on mats, etc., adhesive is applied to the pile surface of the mat in an appropriate pattern and then colored! There are two methods: the Frotzky method, in which fibers are electrodeposited, and the cut-out method, in which carpets and carpets of different colors are cut out at the same time in a pattern and fitted together.Although both can produce clear patterns, they are expensive and have low productivity. low.

Another problem was that it took time to create and change patterns.

Furthermore, in the Frotzky method, the patterned parts are hardened with adhesive, resulting in a pile-like appearance, and in the cutout method, there is a lot of loss and sometimes the strength is low.

Furthermore, it has been almost impossible to apply conventional methods to thin spun yarns.

(Problem of the Invention) The object of the present invention is to obtain a dust control mat with a clear pattern by overtufting a base material that has been tufted once.

(Means for Solving the Problems) The present invention provides a base material in which a primary pile is formed on a base fabric.
The gist of the mat is a dust control mat, in which the secondary pile is formed in a pattern by overtufting on a base material made of spun yarn impregnated with an antifouling oil agent.

This will be explained below based on the drawings.

FIG. 1 is a sectional view of the bail base material.

l is a normal primary base fabric for tufting made of non-woven fabric or flat yarn woven fabric, and tufting is performed on this base fabric to form a cut pile or loop primary pile 2 with a relatively short pile length, and the pattern of the present invention is This becomes the base material 3 of the carpet. This pile yarn is a spun yarn of nylon, polyester, acrylic, etc.

This spun yarn is preferably relatively thin, with numbers 15 to 7, and 1 to 5 single yarns of these spun yarns are twisted and used. A preferred embodiment is a 15th number spun yarn with 3 twists to a 7th number spun yarn with 4 twists.

The above-mentioned spun yarn is impregnated with an antifouling oil agent such as spindle oil, machine oil, liquid paraffin, alkylbenzene oil, alkyl naphthinate oil, etc. for imparting dust control properties, that is, dustproof properties.

FIG. 2 to FIG. 5 are illustrations of manufacturing process examples of the dust control mat of the present invention.

Reference numeral 4 designates a rocker arm, and a needle 5 is attached under the rocker arm. When the switch is turned on, the needle 5 moves up and down at high speed while being supported by the needle plate 6, as shown by the arrow a. At this time, the bottom dead center of the needle is above the base material 3, and the control device 7 of the desired pattern
The tip of the needle will not penetrate the base material 3 unless the pattern data is manually input.

When a signal from the computer is inputted to the pattern control device 7 so as to form a pattern, the stretching device 8 operates and the needles are stretched.

At this time, the relationship between the pattern control device 7 and the extension H position 8 is such that, for example, in FIG. 2, the latch mechanism is disengaged, so the needle remains short, but in FIG. The needle is pushed downward by the bushing rod in response to a signal based on the data, and at the same time the latch mechanism is actuated, and the needle extension device 8, such as a spring, is extended and locked in this extended state, causing the needle to tuft as shown by arrow A. As a result, the tip 9 of the needle penetrates the base material 3, and the pile yarn is captured and cut by the looper 10 and knife 11 to obtain a secondary pile row 12.

To illustrate and explain the latch mechanism of the present invention with reference to FIG. 4, when a signal is input from the computer 18 to the tufting machine to tuft the needle 6 based on pattern data, the needle 5 is pushed down by the bushing rod 17, and at the same time the tufting mechanism is The latch cylinder 15 in the cylinder bar 13 of the control device 7 is pushed by air pressure 16 and the latch cylinder 1
4 fits into the needle.

Here, the needle 6 is held in an extended state by an extension device 8.

As a result, the needle 5 is tufted in an elongated state, and a desired pattern is formed on the base material.

In addition, if the secondary pile is not formed, the pattern control device 7 receives a signal from the computer 18 indicating that tufting will not be performed, and at the same time the air pressure 16 disappears, the latch cylinder 15 moves to the right in the drawing, so that the latch pin also fits into the needle. The needle 6 moves upwards as the lengthening device also works to shorten the needle.

As a result, the needle 5 again only moves up and down at high speed above the substrate.

When the pattern control device 7 receives a signal to stop pattern formation again, the latch mechanism is released, the needle returns to its original length, and the needle vibrates up and down on the base material 3 again as shown by arrow a. On the other hand, a pattern 19 made of cut pile is obtained on the base material 3.

In the present invention, the cut pile 1 on which the pattern 19 is formed
It is desirable that the 202 secondary pile yields a pile fabric that is longer than the primary pile 2 forming the base material 3.

In the present invention, both the primary pile and the secondary pile may be loop pile or cut pile.

FIG. 6 is a cross-sectional view in the flow direction of the patterned carpet obtained, in which a short primary pile 2 is tufted onto a base material 1, and a secondary pile 12 is overtufted using this pile fabric as a base material. An arbitrary pattern 19 is formed.

At this time, the pile 12 may be dyed with a plain color,
It may also be a space-dyed yarn.

Note that, if desired, a portion of the secondary pile that is longer than the primary pile may be cut.

The dust control mat of the present invention is made of nitrile-butadiene rubber (NBR), SBR, chloroprene rubber,
The backing material 20 is formed of resin such as PvC.

Further, if necessary, the obtained dust control mat is fitted into a synthetic resin mat base.

The primary pile is a relatively thin spun yarn and is impregnated with an antifouling oil agent, and the synergistic effect of these factors significantly improves the dust removal performance.

Furthermore, since the secondary pile is formed by overtufting, a clear pattern can be obtained.

Example 1: A base fabric of polyester woven fabric was impregnated with spindle oil.
A primary pile was formed by tufting a spun yarn of acrylic fibers with a second twist of 4 to a height of 12 mm with a pile weight of 710 g/TII' to prepare a base material for a dust control mat of the present invention.

A nylon filament pile yarn with a pile height of 18 mm was overtufted onto this base material to form a secondary pile in a specific pattern. This carpet was lined with NBR resin to obtain a dust control mat of the present invention.

The obtained mat was fitted into a mat base made of PVC and used as a store mat.

The mat of the present invention has dust removal properties and a clear pattern, and has novelty not found in conventional store mats.

■ ■ (Effect of the invention) Excellent dust removal performance was obtained.

The design of the long overtufted secondary pile section could be chosen arbitrarily, regardless of its size.

■ Since the dollar moves independently one by one against the handle, the secondary pile pattern was accurate because the dollar worked under the command of the pattern information.

High productivity and low cost.

Since the pattern information is managed by a computer, the pattern can be easily recalled and changed simply by storing it on a floppy disk. There was no wastage of material costs and the consumption of pile yarn was efficient.
