Problems solved by technology

Due to the low elongation of ordinary base fabrics, the elongation of warp and weft is very different, the elongation of furniture leather produced by using these base fabrics is low, and the processability and effective use rate of the products are low.

Embodiment Construction

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0024] A PVC furniture leather, the base fabric is 2.5D×51mm or 2.5D×38mm polyester staple fiber needle punched non-woven fabric prepared as raw materials, and its weight is 130-180g / m 2 , The resin layer is PVC resin.

[0025] Its manufacturing method see figure 1 .

[0026] Use an automatic metering system to measure PVC powder, plasticizer, stabilizer, and calcium carbonate, and then stir in the mixing tank at high speed for 5min-7min. This step controls the material temperature at 95℃-105℃.

[0027] Then add color materials or additives and mix for 4.5min-5.5min in a 10,000-horsepower machine. In this step, the temperature of the material is controlled at 150°C.

[0028] Then it is mixed in the second rolling mill. This step controls the material temperatu...

Abstract

The present invention relates to PVC furniture leather and a method for manufacturing the PVC furniture leather. The PVC furniture leather comprises a foundation fabric, and is characterized in that the foundation fabric is a needle-punched non-woven fabric. The method for manufacturing the PVC furniture leather is characterized in that a step of foundation fabric sizing is saved compared with the prior method for manufacturing the PVC furniture leather. The present invention selects the needle-punched non-woven fabric with close warp and weft elongation rates, thereby not only improving the hand feel and the processability of products, increasing matching property of leather and good adhesive property between the surface and the leather, but also saving a sizing process and reducing manufacturing cost.

Description

Technical field [0001] The invention relates to a PVC furniture leather, and also relates to a manufacturing method of the PVC furniture leather. Background technique [0002] With the continuous improvement of people's quality of life, the material and comfort requirements of all kinds of furniture are also increasing. At present, the common synthetic leather for furniture (referred to as furniture leather) on the market is produced by using common base fabric and paste. Due to the low elongation rate of ordinary base fabrics, the warp and weft elongation rates are quite different. The furniture leather produced with these base fabrics has low elongation rate, and the processability and effective use rate of the products are low. Such products are far behind the market requirements of furniture leather. Only by inventing a product with high elongation and close elongation in the warp and weft directions can it truly meet the market needs. [0003] The current manufacturing meth...
