する要求品質が厳しくなる傾向にある。2. Description of the Related Art In recent years, foamed PVC cushion floors (hereinafter referred to as cushion floors) have been widely used as building interior materials. Generally, these cushion floors are
From the viewpoint of dimensional stability and imparting strength, it is used in combination with sheet materials mainly composed of glass fiber and pulp. As a pattern for this cushion floor, a pattern or a geometric pattern was used before, but the flooring-like wood grain pattern has been rapidly spread due to the Western-oriented lifestyle, and the surface smoothness and delamination strength are increasing. There is a tendency that the required quality for the above becomes strict.

面平滑性は不十分なものである。For example, Japanese Patent Laid-Open No. 55-16901 proposes a method in which a thermoplastic resin powder such as a vinyl chloride resin and a reactive resin are contained in glass fibers at a specific ratio to form a sheet. However, the amount of adhesion of the thermoplastic resin powder, the so-called yield, is limited, and due to the permeation of PVC sol into the voids between the resin powder, the permeation of PVC sol becomes uneven throughout the cushion floor, and the surface smoothness is Is inadequate.

なり，表面平滑性は不十分なものである。Further, Japanese Patent Application Laid-Open No. 57-106772 proposes a method of attaching a polyfluoroalkyl group-containing compound to a porous non-woven fabric substrate made of inorganic fibers such as glass fibers. Although the amount of compound adhering is limited and the adhesiveness with PVC sol is excellent, due to the penetration of PVC sol into the voids of the porous body, the permeability of PVC sol becomes non-uniform on the entire cushion floor, and The smoothness is insufficient.

る。In Japanese Patent Laid-Open No. 01-164913, a surface layer mainly composed of thin and short glass fibers is provided on the surface of a central layer composed mainly of glass fibers having a specific average fiber diameter and average fiber length. However, since only glass fiber is the main component, the permeation amount of PVC sol is large,
Further, the delamination strength between the central layer and the surface layer is insufficient.

す。Comparative Example 1 A secondary processing raw fabric having a basis weight of 80 g / m 2 obtained in the same manner as in Example 1 was impregnated with 2 g / m 2 of a secondary processing binder having the following composition. , Basis weight 82 g / m 2

The finished sheet had fine irregularities, poor surface smoothness, low interlaminar peel strength, and a large amount of polyvinyl chloride sol permeation into the sheet, indicating partial strike-through of the sol. This is probably because the amount of impregnated polyurethane resin is small and the masking effect of polyurethane resin on the entire sheet is insufficient. The evaluation results are shown in Table 1.

The resulting sheet had slight irregularities on the surface, and although the amount of sol penetration was small, the delamination strength was low. It is considered that this is because the ionicity of the polyurethane resin is anionic, resulting in nonuniformity of the masking effect due to variations in resin fixing property to the sheet, and small adsorption and adhesive force to pulp during sheet formulation. The evaluation results are shown in Table 1.

A sheet having a basis weight of 460 g / m 2 was obtained. The resulting sheet had large irregularities, poor surface smoothness, low interlaminar peel strength, and a large amount of permeation of polyvinyl chloride sol into the sheet. This is considered to be because the sheet filling effect and the interlaminar strength are insufficient with only glass fiber and pulp. The evaluation results are shown in Table 1.
