Instructions for the use of polyester masterbatchs

In the actual spinning application, the maternal granules should be adjusted according to different single silk fibrousness, silk and slicing performance (including light or light), and the spinning processing process. It is recommended to control the temperature at 280 ~ 295 ° C. Polyester -colored female grains have a strong hygroscopic resistance. It is recommended to pre -dry it before use, so as not to bring too much moisture into the melt, affecting the quality of processing.

Polyester masterbatch products include: polyester FDY -colored mother grains, polyester DTY female grains, polyester ATY female grains, polyester BCF color mother grains, polyester fine -grained female grains, polyester short fiber -colored female grains, polyester non -woven fabric color color Mother grains, PET bidirectional stretching membrane color mother particles, polyester night light mother particles.

There are two main types of raw materials used by polyester masterbatchs: color agent and carrier. Depending on the coloring agent and carrier, some female grains also need to add auxiliary agent. Generally, if the color agent is organic or inorganic pigment, the carrier uses a low melting point polymer, and appropriate additives are generally needed. If the coloring agent is selected from polyester soluble livestock dyes, and the carrier is polyester itself, there is generally no need to add any additives. The previous situation is similar to the general plastic mother granules, but the requirements of various indicators are higher, and it will not be repeated here. If high -end polyester masterbatch particles are prepared, such as long silk -class polyester -colored maternal particles, it is generally believed that polyester soluble dyes are generally considered to be good.

  Suzhou Polydi Materials Technology Co., Ltd. was founded in May 1995. We have focused on 20 years. From the beginning of its establishment, we have been dominated by production polyester (PET) and nylon (PA) chemical fiber -colored maternal grains. It has developed into a high -tech enterprise integrating scientific research, development, production and marketing.
