Reasons Why Embroidery Thread is Prone to Breaking

A computerized embroidery machine is a high-precision, high-efficiency sewing device that combines electrical control and mechanical systems. It is widely used in industries such as embroidery, clothing, textiles, knitting, footwear, lace, curtains, and handicrafts. The quality of embroidery and the thread breakage rate are key indicators to evaluate the quality of the machine. The quality of embroidery determines the precision of the machine and the finesse of the embroidery. The embroidery thread breakage rate also directly affects the production efficiency of the machine and the economic benefits of the factory.


The problem of heavy duty embroidery thread breakage is the most common problem in embroidery machines. The reasons for thread breakage include factors such as embroidery techniques, operator skills, computer parameters, material compatibility, factory conditions, and the environment. The problem can result from a combination of several factors.


Analysis and processing of thread breakage problems require specific problem analysis. Specific analysis of the peculiarities of the problem can enable the identification of the correct approach to solve the problem.


The reasons why embroidery thread is prone to breakage can be divided into the following categories:


  • Quality problems of the thread itself (when still required for use, oil or wax can be applied to the thread, or even reduce the speed to keep it).

  • Abnormal threading or wind blowing directly onto the thread rack causing thread knotting;

  • The thread spool is inclined or the thread has too many joints;

  • The gold and silver threads are knotted, causing breakage;

  • Needle installation is incorrect or skewed (a new needle may need to be replaced);

  • The needle has glue stuck to it (a cloth dipped in oil can be used to remove the glue);

  • The tension of the embroidery thread is abnormal;

  • The needle step of the plate is too dense or there are needle traces shorter than 0.5mm;

  • A needle that is too small is used;

  • In thick embroidery fabrics, an accordion needle or Groz-Beckert needle was not selected;

  • The machine speed is too fast, and not adjusted according to the characteristics of the embroidered material;

  • When doing applique embroidery, the bobbin needs to be cleaned regularly, or the oiling cycle increased;

  • The embroidered material is too thick and hard, and oil or wax can be applied to the thread, if necessary;

  • The wrong twist thread was used.

Factors other than the machine that affect needle breakage:


  • Abnormal threading or wind blowing directly onto the thread rack causing thread knotting;

  • The thread spool is inclined or the thread has too many joints;

  • The tension of the thread is abnormal;

  • The needle step of the plate is too dense or there are needle traces shorter than 0.5mm;

  • A needle that is too small is used;

  • The machine speed is too fast, and not adjusted according to the characteristics of the embroidered material;

  •  When doing applique embroidery, the bobbin needs to be cleaned regularly, or the oiling cycle increased;

  • The embroidered materials are too thick and hard (oil or wax can be applied to the thread, if necessary);

  • The materials move around during embroidery (necessary to improve the fixing method);

  • Too many stitches in thick embroidered materials;

  • In thick embroidery fabrics, an accordion needle or Groz-Beckert needle was not selected;

  • The bobbin has not been installed correctly.


Firstly, let's talk about the raw material of the polyester embroidery thread wholesale, which includes sticky long silk, polyester long silk, polyester special-shaped silk, and nylon long silk. 


Embroidery thread is made by twisting long filament, and many companies with outdated technology have equipment defects that can cause single filaments to twist, leading to problems with breakage. In the daily production process of embroidery thread, another issue is that employees of companies tie knots on the thread heads with too much length. All these factors can easily cause breakage when the user is using the machine.
