Introduction of polyester masterbatch:

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

There are two main types of raw materials used in polyester masterbatches: colorants and carriers. According to the different colorants and carriers used, some masterbatches also need to add additives. Usually, if the colorant is an organic or inorganic pigment, and the carrier is a low-melting polymer, it is generally necessary to add appropriate additives. If the colorant is polyester soluble dye, and the carrier is polyester itself, generally no auxiliaries need to be added. The former situation is similar to the general plastic masterbatch, but the requirements for various indicators are higher, so I will not repeat it here. If preparing high-grade polyester masterbatch, such as filament-grade polyester masterbatch, it is generally considered that polyester soluble dyes are used, and polyester itself is better as the carrier.

Polyester masterbatch products include: polyester FDY masterbatch, polyester DTY masterbatch, polyester ATY masterbatch, polyester BCF masterbatch, polyester fine denier masterbatch, polyester staple fiber masterbatch, polyester non-woven color masterbatch Masterbatch, PET biaxially oriented film masterbatch, polyester luminous masterbatch.

Instructions for use of polyester masterbatch

In actual spinning applications, the addition ratio of masterbatch and the spinning process should be adjusted according to different monofilament fineness, filament shape and chip performance (including gloss or extinction). It is recommended to control the temperature at 280~295℃. Polyester coloring masterbatch has strong hygroscopicity, it is recommended to pre-dry it before use, so as not to bring too much water into the melt and affect the processing quality.

Suzhou Baolidi Material Technology Co., Ltd. was established in May 1995. We have been focusing on 20 years and have been producing polyester (PET) and nylon (PA) chemical fiber masterbatches since the very beginning.
