Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0028] The napped composite needle-punched formable carpet of the present invention is mainly composed of two layers: the surface layer of the carpet and the bottom layer of the carpet. The surface layer of the carpet and the bottom layer of the carpet are combined by needle punching and heat setting. The thickness parameter of carpet sound absorption and sound insulation.

[0029] The manufacturing method of the napped compound needle-punched formable automobile carpet of the present invention comprises the following four steps: A. production of the carpet surface, B. production of the carpet bottom layer, C. needle-punching compounding of the ca...

Abstract

The invention discloses a manufacturing method of a frieze combined needle-punched formable carpet. The method includes the following steps: A, opening, mixing, carding and lapping fibrous materials according to a preset proportion to form a uniform fiber web, forming carpet surface layer grey cloth by bonding via a pre-needling process, and then performing needled friezing on one side of the carpet surface layer grey cloth via a main needling process by taking a used support mesh plate as a brush which is made of a plurality of bristles with the diameter of 0.20-0.30mm and with the pore diameter of gaps formed between the bristles of 0.10-0.15mm; B, opening, mixing, carding and lapping fibrous materials according to a preset proportion to form a uniform fiber web, forming a carpet bottom layer by bonding via the pre-needling process, and combining the carpet surface layer in the step A and the carpet bottom layer in the step B to obtain the combined needle-punched carpet; D, rolling up, stentering and baking the combined needle-punched carpet in the step C to obtain the frieze combined needle-punched formable carpet.

Description

technical field [0001] The invention relates to a method for manufacturing a piled composite needle-punched formable carpet, in particular to a method for manufacturing a piled composite needle-punched formable automobile carpet that can be used as an automobile interior carpet. Background technique [0002] Now that the automobile industry has developed into a high-speed mature stage, the competition in the global automobile industry market is very fierce, and the traditional low-grade needle-punched nonwoven automotive interior materials can no longer meet the needs of the development of the modern automobile industry. Therefore, research on new needle-punched nonwoven automotive interior materials has become a current trend. [0003] In the traditional production technology of needle-punched nonwovens for automotive interior materials, the support plates used in the needle-punching process are usually metal support plates. The diameter of the hole of the metal support pl...
