Embodiment 1

[0200] The printing liquid A was applied to the adhesive-attached surface of the adhesive-bonded nonwoven fabric using a cylinder, and then dried with a dryer at a temperature of 150°C.

[0201] And, finally, it is supplied to a Reliant Press machine (temperature: 150° C., pressing pressure: 2 kgf, processing time: 12 seconds), thereby manufacturing an adhesive-bonded non-woven fabric with printing from printing solution A on one main surface. The surface material for the interior of the layer (mass per unit area: 212g / m 2 , thickness: 1.3mm, air permeability: 46.1cc / cm 2 / sec, mass per unit area of ​​the printing layer: 30g / m 2 , average particle diameter of hollow particles: 73.0 μm, CV value: 8.4%).

[0202] The SMD of the main surface where the printed layer was exposed of the surface material for interior manufactured in this way was 2.09 micrometers, MIU was 0.45, and MMD was 0.015.

Embodiment 2

[0204] Except using printing liquid B instead of printing liquid A, in the same manner as in Example 1, a surface material for interior decoration ( Mass per unit area: 212g / m 2 , thickness: 1.4mm, air permeability: 55.5cc / cm 2 / sec, mass per unit area of ​​the printing layer: 30g / m 2 , average particle diameter of hollow particles: 105.6 μm, CV value: 15.9%).

[0205] The SMD of the main surface where the printed layer was exposed of the surface material for interior manufactured in this way was 2.21 micrometers, MIU was 0.45, and MMD was 0.015.

Embodiment 3

[0222] Except that the processing time of the Reliant Press machine was changed to 20 seconds, in the same manner as in Example 1, a printed layer from printing liquid A was produced on one main surface of the adhesive bonded nonwoven fabric. Surface material (mass per unit area: 212g / m 2 , thickness: 1.1mm, air permeability: 42.4cc / cm 2 / sec, mass per unit area of ​​the printing layer: 30g / m 2 , average particle diameter of hollow particles: 73.0 μm, CV value: 8.4%).

[0223] The SMD of the main surface where the printed layer was exposed of the surface material for interior manufactured in this way was 1.98 micrometers, MIU was 0.44, and MMD was 0.012.

Abstract

The purpose of the present invention is to provide an interior trim surface material having an improved texture. This interior trim surface material comprises a print layer on at least one main surface of a fiber aggregate body, wherein the interior trim surface material comprises a main surface (the main surface of the interior trim surface material on which the print layer is exposed) having a surface roughness (SMD) lower than 2.71 [mu]m and an average friction coefficient (MIU) greater than 0.27. When these conditions are satisfied, it is possible to provide an interior trim surface material that has an improved texture, such as a feeling of high moistness, while still imparting a sensation that feels smooth and fine to the touch. This interior trim surface material comprises a print layer containing hollow particles having an average particle diameter of 106 [mu]m or less, whereby a feeling of resistance or sliminess is imparted, thereby achieving an interior trim surface materialhaving an improved texture, such as a feeling of high moistness.

Description

technical field [0001] The invention relates to a surface material for interior decoration. Background technique [0002] Conventionally, fiber aggregates (for example, fiber webs, nonwoven fabrics, woven fabrics, knitted fabrics, etc.) have been used as constituent members of surface materials for automotive interiors. [0003] As a surface material for interior decoration provided with fiber aggregates, the applicant of the present application proposes "needling reinforcement treatment is performed on one side of the fiber web, and after the adhesive is impregnated on the surface subjected to the needle punching reinforcement treatment, the Calendering treatment, followed by impregnating a low-viscosity adhesive on the surface opposite to the needle-punched reinforcement treatment surface material for interior decoration" (Patent Document 1), and "A needle-punched nonwoven fabric Fuzzing on the surface is suppressed, and a resin is impregnated on the fuzzing-suppressed su...
