Problems solved by technology

However, these patent documents do not disclose the use of the flame-retardant polyester fiber or flame-retardant polyurethane to manufacture flame-retardant similar leather sheet-like substrates. Moreover, the surface strength such as abrasion resistance or peel strength is good, and the flame retardancy is similar to leather sheet substrates. These patent documents do not have any hint

[0148] "Manufacturing Examples 1-4" [Manufacture of polyester, spinning and manufacture of staple fiber]

[0149] (1) In terephthalic acid and ethylene glycol, 0.04 mass % of titanium dioxide is added based on the mass of terephthalic acid, and antimony trioxide is added in a ratio of 500 ppm based on the mass of terephthalic acid. Heating is carried out under the condition of 2.0 Pa, the esterification reaction is carried out until the esterification rate is more than 95%, and the oligomer is produced. Add the oligomer and reactive phosphorus flame retardant (M-Ester manufactured by Sanko Co., Ltd., molecular weight 434, phosphorus atom content 7% by mass) according to the ratio shown in Table 1 below. , Under a reduced pressure of 40.0 Pa, it is melt-polymerized to generate a prepolymer with an intrinsic viscosity of 0.65 dl / g, and the prepolymer is extruded into strips through a nozzle, and cut into small cylindrical pieces. After pre-drying the pellet at 120°C for 2 hours...

Abstract

The flame-retardant leather-like sheet substrate of the present invention comprises a layer (A) that is made of an entangled nonwoven fabric comprising a polyester superfine fiber (a) of a single fiber fineness of 0.5 dtex or less containing no flame-retardant component and a flame-retardant polyester superfine fiber (b) of a single fiber fineness of 0.5 dtex or less containing a flame-retardant component in a ratio, (a) / (b), of 100 / 0 to 40 / 60 by mass, and a layer (B) that is made of an entangled nonwoven fabric comprising the polyester superfine fiber (a) and the flame-retardant polyester superfine fiber (b) in a ratio, (a) / (b), of 70 / 30 to 0 / 100 by mass. The entangled nonwoven fabrics of the layers (A) and (B) are impregnated with an elastomeric polymer (c) containing a flame-retardant component. The ratio of the polyester superfine fiber (a) and the flame-retardant polyester superfine fiber (b) in the flame-retardant leather-like sheet substrate is 10:90 to 90:10 by mass. The flame-retardant leather-like sheet substrate and the artificial leather made thereof have an excellent flame retardancy, a soft and high-quality feeling and appearance, a high abrasion resistance and peel strength, and excellent mechanical properties such as surface strength.

Description

technical field [0001] The present invention relates to a flame-retardant leather-like sheet-like substrate and a manufacturing method thereof, an artificial leather using the flame-retardant leather-like sheet-like substrate, and a chair or vehicle seat using the artificial leather as a surface layer. More specifically, the present invention relates to a flame-retardant leather-like sheet-like base material having a soft and high-quality feel, good surface strength such as abrasion resistance or peel strength, and a method for producing the same, and the use of the flame-retardant material. Artificial leather with properties similar to a leather sheet substrate. The flame-retardant leather-like sheet-like base material of the present invention and the artificial leather using the base material are suitable for making use of the above-mentioned characteristics, having a high-end feel, and requiring high surface strength such as flame retardancy and high abrasion resistance or ...
