Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a draft sheet that is used as an intermediary between the surface on which the article is placed and the article in order to prevent the placed article from easily coming off and moving due to external force. Floor surface Kf in %
This is intended to prevent the carpet from shifting during use.

Carpets are sometimes used without being stuck to the floor so that they can be easily removed during cleaning or cleaning.

This building can be used as a car mat, entrance mat,
Washroom mats, accent racks (placed in a part of the room), and electrically heated carpet surface heating covers are often installed at equal pressure, but these carpets are relatively small (less than 4 knots are stable). The carpet required for this is flexible and finished in the shape of a slab, so it tends to shift due to foot pressure during use.To prevent this, the carpet backing has INK rubber elasticity One method is to interpose a cloth or a sponge with a high friction coefficient, or to paste it together, but depending on these methods, the carpet with cut pile wool that is stuck to the floor surface (hereinafter referred to as −
It is not possible to prevent displacement that occurs when a relatively smaller carpella (hereinafter referred to as a secondary carpet) is placed on top of a secondary carpet.

This sliding movement of the secondary carpet is caused by the zero-pile hair of the secondary carpet tilting in a direction due to the foot pressure received from the top of the secondary carpet, and the secondary carpet that is in contact with the photoelectric current of the tilted pile raising. When there is a slight K shift and the foot pressure is removed, i.e., when walking, the pile raising of the K-next carpet returns to its older llff state due to its elastic reversal. This is explained by the fact that the secondary carpet is not pulled back to its original position, and therefore the secondary carpet gradually shifts and moves significantly due to the foot pressure that is applied as it retreats during frequent walking.

Therefore, the present invention aims to effectively prevent not only the slippage vl on a flat surface such as linoleum but also the sliding movement on a primary carpet.

That is, according to the present invention, an undersheet is provided on the back side of the carpet to prevent slippage, and this undersheet contains one granule on at least one side of the base sheet and rubber noble elastic on the surface of the granule. It is formed by coating and fixing the polymer i1C, and providing irregularities due to its particles.

The figure shows an embodiment of the present invention, and in the figure 1
is an underlay sheet, coated with the latex composition layer 3.3 in Table II of the base sheet 2, and one side of which has rubber elasticity (the property of easily deforming easily and greatly elastically even by a slight external force). The granules 4 are sprayed together with a solution of a polymeric material 95 having a polymer material 95, and as the solvent of the polymeric material solution evaporates, the granules 4 are coated with the polymeric material 95, forming a substrate sheet (K).
It adheres and forms a convex portion on the surface of the underlay sheet.

As the base material sheet, a rutted cloth or a non-rutted cloth such as KiF or one having dimensional stability in the lateral direction is used.

The granules are non-foamed or low-foamed (1.2 to 3 times larger), preferably 5 to 30 mesh rods [K crushed polygonal ones are used.

As the polymer material for coating the surface of the granules, a natural or synthetic rubber latex or a Sanga resin emulsion such as acrylic or ethylene vinyl acetate blended with tack fire is used. In this case, appropriate amounts of auxiliary agents such as crosslinking agents, vulcanizing agents, anti-aging agents, and thickening agents are added and used. ) and should not be added in large amounts.

To test the surface of the granules with these polymeric substances 1 having noble rubber elasticity, mix the granules with a latex compound, which is a polymer storage, as described above, and spray this onto the base sheet to prevent adhesion. Sometimes, a latex compound mixed with granules is coated on a base sheet using a roll coater.
It is best to apply it using equal pressure with a doctor or a doctor.

In this case, the combined weight ratio of the latex compound and the granules is 100:50, 150% in the vertical direction, and the coating I on the base sheet is 0.5 to 2 odors. +1!Adjust as appropriate depending on the cloth t#'i must.

Father, base material sheet) Apply K adhesive, sprinkle granules on it, and then apply latex compound, or use 4P as necessary.
According to K, such scattering of the granules and application of the latex compound are carried out several times on the surface of the base material sheet so that several granules come together to form one convex part. It is also possible to adhere to the base sheet while coating it.

Therefore, according to the present invention, the attachment *m of the granules is the primary carpet)
61C, when interposing an underlay sheet between the secondary carpet 8 and the secondary carpet 8, (1) The convex portion 4 made of particles on the surface of the underlay sheet digs into the hair 7 of the secondary carpet and produces an anchoring effect. .

(2) Since the surface of the convex part formed by the crushed granules has irregularities, the anchoring effect of the convex part, which is hugged by the fibers of the pile napped of the primary carpet and dug into it almost completely, is promoted.

G) The surface of the convex part formed by the granules is coated with a polymer 5 which has an extremely high coefficient of friction without adding any filler at all, and the surface of the convex part and the intertwined fibers of the hairs. A pressure-adhesive gauze is maintained between the carpets and the anchoring effect is promoted to prevent the underlay sheet from sliding on the secondary carpet.

(4) Because the underlay sheet is legible, it fully adheres to both the 1114 side of the construction method carpet and the long side of the secondary carpet, and as it is easily displaced and moved in this way. displacement is effectively prevented.

(5) Since the convex portions of the underlay sheet are composed of negative rubber particles, even when placing this on the linoleum floor and supporting a carpet such as an entrance mat, the convex portions do not damage the linoleum floor. The friction force of the polymer material coating the surface also prevents the carpet from shifting.

As is clear from the above, the convex portions of the present invention are not mere protrusions that act as spikes, but have the property of tightly intertwining with the pile 9 hairs of the Goji carpet on the surface thereof, and that they are suitable for flat surfaces such as linoleum flooring. Ayu is a book that is characterized by an elastic hairstyle that fits even against sharp 1iQK,
This is convenient in preventing the carpet from shifting.

The same sheet (according to the present invention) can be placed on a chair and used under a cushion to prevent the cushion from shifting, and can also be decorated on one side without forming a convex part due to particles. It can also be used as a seat cover that does not shift by giving it elasticity, and it is also possible to obtain a carpet that does not shift by attaching the backing of the carpet to the surface using the underlay sheet as a secondary base fabric. The present invention also has practical effects in this respect.
