Problems solved by technology

Therefore, non-woven fabrics are not suitable for automotive interior materials that require various appearances and excellent moldability
In addition, as the driving speed of automobiles becomes faster due to the improvement of automobile engines, it is necessary to improve the sound absorption performance of interior materials to provide a comfortable driving environment during high-speed driving, but if non-woven fabrics like most interior coverings With a smooth surface like leather material, the sound absorption performance is reduced
[0005] Meanwhile, a method of forming various patterns on textile fabrics by an etching method has been proposed, but it can only be achieved by an etching method using a laser etching device (see Korean Patent Registration No. 10-0771071)

Embodiment approach 1

[0068] Embodiment 1: Coating method

[0069] The method of chemical coating (or adhesive coating) of the present invention is shown in Figure 9 middle.

[0070] The coating device comprises a pair of rollers, and one or both surfaces of the nonwoven may be coated by at least one coating device. If the nonwoven fabric passes between the pair of rollers rotating in opposite directions based on the central axis, an adhesive is added to one of the rollers and the surface where the nonwoven fabric adjoins each other, so that the surface of the nonwoven fabric is coated with the adhesive. the surface. ACRYSOL 890, Acrylic Emulsion DK-6800 DK Chem or EW-100S SKI PETRESIN available from DKC were used as binder.

[0071] At this time, the surfaces of the nonwoven fabric contacting the two rolls may be the same (front surface coating), or may be different (back surface coating). In addition, double surface coating is possible if front surface coating and back surface coating are ca...

[0072] Embodiment 2: Printing method

[0073] The printing method using the trommel method uses a printing unit in which the trommel contacts a guide roller ( Figure 10 ). With the non-woven fabric in the first color printing unit's gondola roll ( Figure 10 a) and guide roller ( Figure 10 Pass between b) in the extrusion rod ( Figure 10 d) Extrusion in the trommel through the binder supplier installed in the trommel ( Figure 10 c) Empty color binder ( Figure 10 In e), so that a part thereof is discharged from the outer surface of the trommel, thereby forming a pattern on the surface of the nonwoven fabric. Because the extrusion rod is arranged in the magnet (electromagnet) ( Figure 10 Within the range of the magnetic field of f) in, so a predetermined amount of color binder is discharged to the outside of the rotary screen by the extrusion rod at a predetermined position, thereby allowing printing. At this time, the resolution of the printed matter pattern can be...

Embodiment approach 3

[0078] Embodiment 3: Alkaline etching method

[0079] An alkaline etching method was performed on the surface of a nonwoven fabric formed of 100 wt% polyester. The alkaline etching method is performed by adding NaOH, a strong alkaline material, on the surface of the fiber to melt the fiber in a regular shape and depth. After printing the surface of the nonwoven fabric with an alkaline material, the printing solution and the melted portion of the nonwoven fabric are separated.

Abstract

The present invention relates to a non-woven fabric for automotive interior materials and a method for manufacturing the same. Said manufacturing method is characterized by printing a surface or back surface of the non-woven fabric and subsequently alkaline etching the back surface of the non-woven fabric. In addition, said manufacturing method may coat the surface or the back surface of the non-woven fabric before the printing process. Accordingly, the present invention provides a non-woven fabric for interior skin materials for automobiles with various shapes, excellent moldability and sound absorbing properties.

Description

technical field [0001] The present invention relates to non-woven fabrics for automotive interior materials, and by performing alkaline etching on said non-woven fabrics in a regular pattern, together with pretreatment methods such as various coatings on the surface of said non-woven fabrics and a method of printing said nonwoven fabric. Background technique [0002] Automotive interior skin materials are mainly manufactured from plastic sheets, woven fabrics and non-woven fabrics. Plastic sheets have excellent moldability, but lack tactility. In addition, woven fabrics have a gorgeous appearance and excellent moldability due to low modulus, but woven fabrics are expensive because they must be used by laminating PU foam on their back side due to their small thickness. In order to solve these problems, non-woven fabrics have been developed and used for interior materials of automobiles. [0003] Non-woven fabrics are a class of fibers that are produced by spreading fibers ...
