About the difference between 108d polyester and 120d polyester:
"People who have used embroidery thread know that usually, the specification of rayon embroidery thread is 120D/2, while the specification of embroidery thread Embroidery Machine Thread is marked as 108D/2 by some manufacturers, and marked as 120D/2 by some manufacturers. But in general, the marking methods of the two are correct, but the angle of understanding is different.
Understand the difference between the specifications of polyester embroidery thread and rayon embroidery thread from the dyeing process of embroidery thread.
Polyester embroidery thread is dyed at high temperature and high pressure. After high temperature and high pressure, polyester yarn has a certain shrinkage, so after dyeing, the thickness of 108D polyester yarn is the same as that of 120D rayon. The dyeing of rayon embroidery thread is under normal temperature and pressure conditions, and the shrinkage of rayon is very small and can be ignored.
Therefore, the thickness of 108D/2 Embroidery Polyester Thread and 120D/2 rayon embroidery thread is the same, which is why 108D polyester thread must be used when making polyester embroidery thread, otherwise, the thickness of polyester embroidery thread will be the same as that of artificial silk. Silk embroidery threads vary in thickness. That is to say, 108D/2 polyester embroidery thread means that the specification of polyester yarn is 108D, and the final embroidery thread is still 120D.
So when the embroidery thread manufacturer tells you that the specification of their polyester embroidery thread is 108D/2, you can safely use it as 120D/2 embroidery thread. On the contrary, if the embroidery thread manufacturer tells you that their polyester yarn is 120D, then you should be careful, because after dyeing, the embroidery thread will become thicker than 120D. "
PS: (Actually, 75d rayon is used as the bottom thread to embroider more softly, but it is easy to break the thread, and it is more expensive, and there are very few 75d rayon on the market. I have asked the manufacturer and said that 75d rayon is all It is easy to break the thread, and embroidery factories are reluctant to use this thread)
When to choose polyester thread?
Look at everyone's needs.
"Polyester embroidery thread is an ideal embroidery thread for clothes that require frequent washing, heavy washing, or frequent exposure to sunlight, such as children's clothing, bed sheets and tablecloths. At the same time, polyester embroidery thread is also recommended for high-speed embroidery, This is because it is stronger than rayon or cotton"
If the picture you embroider is used to make bags, bags, etc. that do not need to be washed frequently, you can use human silk thread. For clothes that are washed frequently, you can choose polyester thread if you are concerned that the silk thread is not easy to break.
