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.

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.

There are two main types of raw materials used in polyester masterbatchs: 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 polyester 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.

  Suzhou Baolidi Material Technology Co., Ltd. was founded in May 1995. We have been focusing on it for 20 years. Since its establishment, we have been leading the production of polyester (PET) and nylon (PA) chemical fiber masterbatches and functional masterbatches. It has developed into a high-tech enterprise integrating scientific research, development, production and marketing.
