Abstract

The invention discloses a regenerated fiber composite internal decoration material dehumidification method which comprises the following steps: the regenerated fiber composite internal decoration material needed to be dehumidified is put in a contact-typed heating press machine, and is pre-heated to 100-400 DEG C for 10-30s with 0.1-0.5 Mpa / cm<2> of pressure. Then the contact-typed heating press machine is opened, ensuring that the surface of the material is completely separated with a hot plate for 5-15s. Lastly, the regenerated fiber composite internal decoration material is re-heated to 180-240 DEG C for 50-100s with 0.1-0.5 Mpa / cm<2> of pressure, in which way the regenerated fiber composite internal decoration material needed to be dehumidified can remove the moisture thereof and can meet the plastic molding requirement. Checked by the criterion of GB / T 9995-1997 Determination of the water content and moisture regain rate in textile materials, the moisture in the regenerated fiber composite internal decoration material is reduced to 0.3 percent which is completely meet relevant requirements. The method of the invention has short flow, high efficiency, good quality, low investment, and is convenient for industrialized production.

Description

technical field [0001] The invention relates to a method for dehumidifying a regenerated fiber composite interior material. The product for the composite material is suitable for car carpet interior materials and trunk cover interior materials in car interiors. Background technique [0002] Due to the rapid development of the world economy and the continuous improvement of people's living standards, the development of the automobile industry, especially the production of cars is changing with each passing day, and the models are constantly updated. Customers have higher and higher aesthetic requirements and functional requirements for vehicle interior materials. [0003] Car carpets and trunk covering materials are becoming more and more important as the functional requirements of car interiors other than decoration. The installation requirements between these two parts and the car carpet, in addition to matching the shape and size, are also important. It is required that t...
