Description

[Detailed description of the invention] The present invention relates to a rug fiber sheet that does not move under pressure in the direction of the fur even if it is layered on a carpet spread on the floor. This invention relates to a rug fiber sheet having a sufficient amount to prevent the sheet from moving.

Conventionally, when a partial-sized carpet (for example, a 2-tatami jaggy), a so-called floor carpet, is laid on top of the so-called floor carpet that is spread from wall to wall in a room, this carpet cannot be placed during use. There was a problem with the carpet being moved under pressure.

Another problem that has recently required rapid improvement is the movement of the covering material of electric carpets under pressure.

Electric carpets are now widely used in general households, but they are still expensive, so to prevent the surface from getting dirty, an additional carpet (so-called cover material) is placed on top of the electric carpet for several years after purchase. It is often used.

In such cases, housewives often complained because the cover material moved under pressure during use.

This type of tread pressure movement of laid-down carpets or cover materials, etc. is a problem that occurs because the cut pile or loop pile of laid-down carpets or electric carpets inevitably has a so-called hair texture that slopes in a certain direction. When a load is applied, the cover material moves as the pile tilts in the direction of the pile, and even when the load is removed and the pile returns to its original shape, only the cover material remains near the moved position and the cover material remains in its original shape. The pedal does not return to its original position, and as this repetition accumulates, the pedal pressure movement becomes noticeable.

In severe cases, it is not uncommon for the pedal pressure to move 30 to 40 cm per day.

In the past, attempts have been made to improve the prevention of such movement of the pedal pressure.

For example, Japanese Patent Application Publication No. 56-60514 proposes a method in which a sheet attached with a cotton-like material to which crepe-like or curl-like cellulose is attached is interposed between carpets.

However, the effect of preventing tread pressure movement is not necessarily sufficient, and there is a demand for improvement, especially in the case of carpets with a large pile length.

The present invention provides a laying carpet, a cover material, an undersheet (a sheet interposed between two laying carpets to prevent stepping pressure movement), etc. that extremely effectively prevents such movement of stepping pressure. It is.

The rug fiber sheet according to the present invention is a rug fiber sheet having an amount of melted and deformed fibers on at least one surface of the sheet to prevent the sheet from moving.

In this specification, one side of one sheet refers to Figures 1 and 8.
1 Refers to the surface indicated by 2 in each of Figure 3B1 and Figure 3C.

Further, 1 in each of FIGS. 1, 2B, 3B, and 3C indicates the base material of the sheet.

In this specification, 1. Melting deformation means that the synthetic fibers constituting the sheet are heated for a very short time using an open flame such as gas burning at 500°C to 1200°C, a high-temperature furnace, or hot air. This refers to the deformation of the fibers on the sheet surface that occurs when

The shape of the melt deformation, including deformation such as shrinkage of the fibers, does not necessarily have to be constant, but it is preferably as shown in Figure 1, Figure 2 B1 Figure 3 B1 Figure 3 C-3. It is preferable to use agglomerated materials because they have a good anti-movement effect.

3 in FIGS. 1 to 5 shows this agglomeration.

In particular, as shown in Figure 4, the ends of single fibers are agglomerated into a shape close to a sphere, and as shown in Figure 5, the ends of multiple fibers are fused together and agglomerated into a shape close to a sphere. is suitable.

In addition, FIG. 2A is a plan view of the surface having an anti-slip effect of the sheet of FIG. 2B, and FIG. Figure B is a cross-sectional view taken in a direction perpendicular to the ridge, and Figure 3C is a cross-sectional view taken along the back of the ridge.

The non-moving rug fiber sheet of the present invention is a rug fiber sheet having melted and deformed fibers on at least one surface of the sheet in an amount sufficient to prevent the sheet from moving. "Yo" refers to the amount necessary to exhibit a movement-stopping effect to the extent that tread pressure movement is virtually unstoppable when the rug fiber sheet is laid over a carpet or electric carpet.

Therefore, the amount of melted and deformed fibers on at least one side of the sheet does not need to be large enough to cover the entire back surface of the rug fiber sheet, and if it is too small, the movement-stopping effect will be insufficient, so there is no need for contact. It is preferable to adjust the amount and size of the molten lumps depending on the condition of the pile.

In a particularly preferred embodiment of the anti-motion rug fiber sheet of the present invention, at least one side of the sheet is covered with an average of 5 to 30 C@, most preferably 10 to 30 C, of rawhide material formed by melting and deforming the fibers per square zero. It has 15 o@.

The products to which the rug fiber sheet of the present invention can be applied are not particularly limited as long as they are required to prevent movement on the carpet, such as floor carpets, electric carpets, cover materials, and undersheets. The materials include tufted carpet, plain weave carpet, two-dollar punch felt, knit, etc., and the material is selected as appropriate depending on the purpose.

In carpets and cover materials, only the surface in contact with the carpet has the anti-movement effect, but when used as an undersheet, both sides of the sheet are processed to have the anti-movement effect.

Synthetic fibers are preferably used as raw material fibers for the rug fiber sheet of the present invention, such as polyester, polypyroprene,
Nylon, acrylic fibers, and especially polyester are preferred.

Several types of these fibers may be used in combination as necessary, and natural fibers and chemical fibers may be used in combination as necessary.

There are no particular restrictions on the thickness of the fibers, but those having a thickness of 1.5 denier to 100 denier are preferably used.

Although there are no particular restrictions on the method of manufacturing the anti-movement rug fiber sheet of the present invention, the following method is preferably adopted.

Punch density about 50-3001 preferably 150-200
Needle punch felt or date approximately 100-80
The sheets of the present invention are produced by passing a zero pile knit through a 500-1200 DEG C. heating device at a rate of about 5-20 r'rI/min.

The heating method used is a gas heating furnace, a line burner, far-infrared heating, etc.

In addition, the non-moving rug fiber sheet of the present invention can be produced by spraying a synthetic resin emulsion with a bottom film forming temperature of 0°C or less on the processed surface in advance, if necessary, prior to the above-mentioned heating. The anti-slip effect of the invented sheet may be further improved.

Such synthetic resins include acrylic resin, EVA,
SBR etc. are used.

In this case, the coating amount is preferably about 50 to about 150 g/-.

The anti-slip carpet fiber sheet according to the present invention can be used when a carpet is laid over an electric carpet,
Furthermore, when interposed between two carpets as an undersheet, it exhibits an extremely excellent movement-stopping effect.

Example 1 (Cover material) Polyester fiber (6 denier 50% 15 denier 50

/d), spray-coat a resin (dry weight 60g/?71″) consisting of Sumikaflex 400 stamped part (Sumitomo Chemical), water 4(2) on the back side of the pile, dry it, and then apply the resin to the sheet. The surface was treated with a direct flame of propane gas.

The treated surface condition was as shown in FIG. 2B.

This was compared with a commercially available cover material for electric carpets made of surface loop pile.

Furthermore, a sheet according to JP-A-56-60514 was prepared and compared.

Comparative test method and results: Place a 20cm x 20cm cover material sample on top of an electric carpet with a surface loop pile (pile length 8mm), apply a load of 1 kg (720cm x 20cm) to 3 items, and unload the cover material sample in the horizontal direction. was pulled and the resistance force was compared using a spring meter.

If the resistance of the commercially available cover material is 100, the resistance of the cover of the present invention was 600.

The resistance of JP-A-56-60514 was 300.

Comparison of wear and performance: Even when the commercially available cover cloth was attached to an electric carpet using a corner cloth, it shifted by an average of 10 cm after one day of use.

The cover material of the present invention was deviated by 2 cm in one week when used in the same manner.

The cover material according to JP-A-56-60514 had an average deviation of 2 crft after one day of use.

Example 2 (undersheet) Polyester fiber (3 denyl 50%, 15 denyl 50%
%) and polyester filament plain woven fabric (weight 80
g/? 71", needle punch felt (weight 35
0g/1ri) and treated both sides with a far-infrared heater.

The condition of the treated surface was as shown in FIG. 1, and the condition of the back surface was as shown in FIG. 2B.

This sheet was used as an undersheet for preventing slippage due to tread pressure of a 2-mat electric carpet used on a loop-pile tufted carpet.

In normal usage without using this undersheet, an average deviation of 20 cm was observed in one day of use.

When using the undersheet of the present invention, there was a deviation of 4 cm after one week of use.

Example 3 (Electric carpet) Needle punch felt (weight 600
g/Po) SBR latex on one side (dry weight 300g/Po)
was applied, and the other side was treated with a direct flame of propane gas.

The treated surfaces were as shown in FIGS. 2A and B.

This felt was used as a backing material for an electric carpet and the SBR latex coated surface was adhered to it.

This electric carpet was used on a tufted carpet (loop pile length 10 mm).
