Introduction of Polyester masterbatch:

Polyester masterbatch has good temperature resistance, excellent filtration performance and long spinning cycle. It is widely used in pre-spinning coloring of polyester filament and staple fiber. In view of the high performance requirements of automotive interior fabric, automotive interior cloth masterbatch, excellent performance indicators, widely used in the domestic automotive industry.

Instructions for using polyester masterbatch

In the actual spinning application, the masterbatch adding ratio and spinning process should be adjusted according to the different monofilaments size, filament shape and slicing properties (including light or extinction). The recommended temperature ranges from 280 to 295 ° C. The polyester coloring masterbatch has strong hygroscopic property. It is recommended to pre-dry the masterbatch before use to avoid excessive water into the melt and affect the processing quality.

Package and store in polyester masterbatch

The product adopts double packing, the inner layer is waterproof and moisture-proof polyethylene film bag, the outer layer is paper-plastic composite bag. Standard packing 25 kg/bag. Please store in a ventilated, dry place, under the cushion, to avoid the sun, rain, master color guarantee its quality up to 5 years. The remaining parts should be re-sealed after opening the package to prevent dust pollution and moisture absorption.

The company mainly produces polyester (PET) and nylon (PA) chemical fiber masterbatch. Masterbatch is a key coloring material for the raw liquid coloring of chemical fiber manufacturers. Chemical fiber mill can directly produce various colored fibers by dyeing before spinning of raw liquid instead of dyeing process of printing and dyeing factory. Compared with chemical fiber dyeing and coloring, coloring with master batch has the advantages of low energy consumption, no pollution, low cost, friendly to the environment, environmental protection and health. It will inevitably replace most dyeing and coloring, so the color master batch industry still has a huge room for growth!
