DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rug used for floors such as carpets and various mats, or a cover sheet rug used for preventing stains on tablecloths, chairs, and seats of various vehicles. The present invention relates to a rug having a large anti-slip effect in which delusion is prevented.

[0002]

2. Description of the Related Art Conventionally, rugs and mats have been used as means for preventing the movement of rugs such as carpets, kitchen mats, bath mats, entrance mats, and toilet mats or mats for figurines such as clocks, vases, pen stands, and various decorative objects. (Hereinafter, these may be collectively referred to as rugs.) A rubber-based substance is lined on the back surface. The rug provided with such means has a certain anti-slip effect on the support surface. For example, Japanese Patent Publication No. 50-12207, Japanese Utility Model Publication No. 60-9
No. 7080, No. 60-144459, a rubber sheet adhered to the back side as described in JP-A-2-157357, or a rug as described in Japanese Utility Model Laid-Open No. 63-7179. An example in which unevenness is provided on the lower surface can be given.

[0003]

However, the rug with the rubber sheet or the unevenness provided on the lower surface as described above has a certain effect of preventing sliding movement. If the area acts action kicks by relatively small fence walking mats motion displacement, it becomes unsightly position shifted each time of walking. Such a situation can be improved by laminating a thick and smooth rubber sheet on the back surface, but the whole rug is heavy and hard, which makes handling difficult. In addition, the conventional anti-slip technology is not suitable for a thin rug such as a chair cover sheet, and when a rubber sheet is stuck, not only does air permeability deteriorate, but also washing becomes difficult. The present invention provides a rug having a large anti-slip effect in which the above-mentioned disadvantages have been solved.

[0004]

The present invention has solved the above-mentioned problems by forming a fiber having excellent anti-slip action into a non-woven fabric and joining the non-woven fabric having high friction to the back surface of the rug.
That is, 10cm on a mirror-finished flat glass placed on a horizontal surface
A sample (non-woven fabric) of 10 cm is placed, and 45
Place an iron plate with a size of 45 mm × 45 mm and a weight of 35 g.
A weight of 00 g is placed and weighted, a string is attached to the end of the sample, and the string is gently pulled in the direction of extension of the glass surface with a hand-type spring balance. The pulling force (g) when the nonwoven fabric starts to move is 70 g or more. The movement of the rug is prevented by joining the high friction nonwoven fabric to the back surface of the rug.

[0005] When a high-friction nonwoven fabric needs a certain thickness and strength, another nonwoven fabric or a reinforcing material such as a woven or knitted fabric is bonded to one surface of the high-friction nonwoven fabric, and the surface of the reinforcing material is changed. It is good to join to the back of the rug. When the rug is a needle-punched nonwoven fabric, the high-friction nonwoven fabric may be joined by needle punching means, and when the base fabric of the rug is a woven fabric, it may be joined by means of an adhesive,
The joining method does not need to be specified.

[0006] high-friction nonwoven, for example, acrylic acid esters and / or main Taku acrylic acid ester 5 to 30% by weight,
Acrylic acid, with ethylene carboxylic acid selected from the main Tactile acrylic acid and maleic acid 0-10% by weight, and their sum is 5-30 wt% ethylene carboxylic acid monomer,
The first component is an ethylene copolymer composed of 95 to 70% by weight of ethylene, and the second component is a thermoplastic resin having a melting point (T ° C.) of 130 <T <270. % Of the composite fiber is used at least 70% by weight. The basis weight of the nonwoven fabric is preferably 30 to 200 g / m ² , and more preferably a nonwoven fabric joined by heat melting of the first component.

[0007] The first component of the composite fibers, acrylic acid ester, a copolymer of ethylene carboxylic acid ester with ethylene, such as main Tak acrylic acid ester, the ratio of ethylene carboxylic acid ester in the copolymer The more the fiber, the better the sliding friction resistance of the composite fiber, but if it exceeds 30% by weight, the rubber-like properties become stronger, the card permeability is poor, and it is difficult to produce a web. When the amount is less than 5% by weight, the sliding friction resistance is reduced, and the proportion of the ethylene carboxylic acid ester in the copolymer is 5 to 30% by weight, preferably 10 to 10% by weight.
25% by weight. The alcohol portion of the ethylene carboxylic acid ester preferably has 1 to 5 carbon atoms, and particularly preferably methyl acrylate and ethyl acrylate.

If the ethylene copolymer is a terpolymer containing ethylene carboxylic acid as a monomer to be added in addition to the above ethylene and ethylene carboxylic acid ester, the surface of the obtained composite fiber is a rubber. The properties are the same or the feeling of stickiness is small, and it comes closer to a normal heat-bonded fiber, and the feeling of touch is no longer unnatural. However, if the amount of ethylene carboxylic acid is too large, it is easy to thermally crosslink during melt spinning, a gel is generated, the melt spinnability is impaired, and the sliding friction resistance is reduced. Therefore, the content of ethylene carboxylic acid is 10% by weight.
The following is good. Also in the case of a terpolymer, the total amount of ethylene carboxylic acid ester and ethylene carboxylic acid is set to 5 to 30% by weight so that the sliding friction resistance is not reduced or the rubbery property is not excessive. The melting point of the ethylene copolymer having such a composition becomes lower as the amount of the ethylene carboxylic acid monomer increases, and becomes higher as the amount of ethylene increases. On the contrary, the melting point of the first component due to the ease of thermal bonding. Is set to be 70 to 130 ° C.

The melting point (T ° C.) of the second component of the conjugate fiber is higher than the melting point of the ethylene copolymer of the first component and lower than the decomposition temperature, and is 1 in consideration of the stability of melt spinning.
30 <T <270. The thermoplastic resin having such a melting point is selected from polypropylene, high-density polyethylene, polymethylpentene, polyethylene terephthalate, polybutylene terephthalate, nylon 6, nylon 66, and nylon 12, and even a copolymer thereof. Good. The structure of the bicomponent fiber has at least 70
%, Preferably 80% or more, of the first component, and the composite ratio (cross-sectional area ratio) of both components is 30% in terms of spinnability and strength.
/ 70 to 70/30 is preferred.

A staple fiber is obtained by melt-spinning a conjugate fiber having the above-mentioned structure using the above-mentioned polymer, drawing it, and cutting it into a desired length. Using this staple fiber,
Card method, cross-layer method, random webber method, wet papermaking method, needle punch method, a method of heating and melting the first component after applying a treatment such as a high-pressure liquid flow method,
Alternatively, a non-woven fabric having high friction can be formed by using a device in which a hot air penetration type heat processing machine and a roll processing machine are combined and applying pressure while melting a low melting point component by a hot roll processing machine.

On the surface of the high friction nonwoven fabric, the above-mentioned conjugate fiber is
When it is present at 0% or more, an excellent anti-slip effect can be obtained. Below this, it becomes difficult to obtain a remarkable anti-slip effect. Therefore, when other fibers are mixed, it is desirable to keep the mixing amount within 20% by weight. The basis weight of the high friction nonwoven fabric is preferably 30 to 200 g / m ² ,
If it is less than m ^2, it will be too thin, and if it is less than 200 g / m ² , it will be too bulky as a non-slip material, and it will not be economically or practically preferable. For applications that require a high friction nonwoven fabric, another sheet material may be joined to the high friction nonwoven fabric.

[0012]

[Function] A rug with a high friction nonwoven fabric bonded to the back surface, for example, in the case of a door mat, the high friction nonwoven fabric is in contact with the floor surface and exhibits a remarkable anti-slip property only by the load of the mat itself. When a person's weight is added due to walking or the like, the sliding frictional resistance further increases, thereby preventing a displacement from a position at the time of laying. In the case of a tablecloth formed by arranging high-friction nonwoven on the back also, because high friction nonwoven is extensively surface contact with the table surface, effectively preventing the movement direction of the table surface, the tablecloth Keep position in order.
