Abstract

PROBLEM TO BE SOLVED: To improve flexibility, shock-absorbing properties and heat shielding properties by thermally fixing a web consisting of stacked synthetic fibers containing a specific amount of thermally adhesive fiber with the help of a needle punch to form fibrous unwoven fabric with a specific basis weight and a specific apparent fiber density, and covering both faces of the fibrous unwoven fabric with a synthetic resin film layer by lamination. SOLUTION: A fibrous unwoven fabric 2 with a basis weight of 150-350g/m<2> and an apparent fiber density of 0.1-0.3g/cm<2> is formed by thermally fixing a web consisting of stacked synthetic fibers containing 5-40wt.% of thermally adhesive fiber with the help of a needle punch. In addition, a synthetic resin film layer 3 is laminated as a coat on both faces of the unwoven fabric 2. If not more than 5wt.% of the thermally adhesive fiber is mixed, the shape stability of the unwoven fabric 2 and its adhesion properties with film are deteriorated. On the contrary, if 50wt.% or more of the thermally adhesive fiber is mixed, the flexibility and shock-absorbing properties of the unwoven fabric 2 are degraded. Further, if the basis weight of its fibrous unwoven fabric 2 is not more than 150g/m<2> , the strength and thermal effects of this carpet is hardly foldable and is bulky so that its handling is difficult.

When a synthetic resin film or sheet alone is used as a rug, a thin film tends to have pinholes and has a problem of waterproofness, and a thick film tends to be curled or creased, and both have insufficient strength. Limited to completely disposable items. On the other hand, cloth-based laminate sheets, which are durable and diversified in design, have high commercial value and are the most popular type, but lack flexibility and elasticity, and have good fit and stability to the ground However, they are not satisfactory in terms of the feel and touch. Further, when the rug is laid on a sandy land where the temperature becomes high in summer or on a frosty lawn in winter, for example, the temperature is directly transmitted to the surface of the rug, causing a discomfort to a person sitting on the rug.

It is important that the content be contained by weight. That is, if the heat-bondable fiber content is less than 5% by weight, the shape stability of the nonwoven fabric and the adhesiveness to the film are inferior, while if the fiber content exceeds 50% by weight, the flexibility and the buffering property of the nonwoven fabric are inferior.

In forming the fibrous nonwoven fabric 2, these fibers are opened and irregularly deposited, and then turned into a fibrous nonwoven fabric through a needle punching step of fixing the fibers with a group of heated needles. This needle punching method is a method suitable for producing a relatively bulky nonwoven fabric, and in a nonwoven fabric satisfying the apparent fiber density and the basis weight range described above, a plurality of times such as coarse pre-punching and dense finishing are performed. It is preferable to perform punching. That is, if the punching is performed in a state similar to the roll embossing, the pressure between the fibers is strongly increased, and it is difficult to obtain a bulky nonwoven fabric.

Specifically, it satisfies a tensile strength of 20 kgf / 5 cm or more, a tensile elongation of 100% or less, and a tear strength of 10 kgf or more. In other words, the tensile strength and tear strength are indications that can sufficiently withstand the use of the rug as a rug, and the tensile elongation is determined by the appearance of the rug, such as the rug being wavy without the subsequent laminate coating following the elongation of the base material. It is a problem factor.
