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, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

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

[0025] For its method of manufacture, 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. In this step, the material temperature is controlled at 95°C-105°C.

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

[0028] Then kneading in the second rolling mill, this step con...

Abstract

The 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 needle-punched non-woven fabric is made of terylene staple fiber with dimensions of 2.5DX51mm or 2.5DX38mm, and the gram weight of the needle-punched non-woven fabric is between 130 and 180g / m<2>. 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 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, but also saving a sizing process and reducing manufacturing cost.

Description

technical field [0001] The present invention relates to a kind of PVC furniture leather, also relates to the manufacture method of this PVC furniture leather. Background technique [0002] With the continuous improvement of people's quality of life, the requirements for materials and comfort of various furniture items are also increasing. At present, the common synthetic leather for furniture (referred to as furniture leather) on the market is produced by adding paste to the common base cloth. Due to the low elongation of ordinary base fabrics and the large difference in warp and weft elongation, the elongation of furniture leather produced using these base fabrics is low, and the processability and effective use rate of the products are low. Such products are far behind the market requirements of furniture leather. Only inventing a product with high elongation and close elongation in warp and weft can really meet the needs of the market. [0003] The manufacture method o...
