The types of commonly used sewing threads are 202, 203, 402, 403, 602, 603 and so on.
The thread is usually formed by twisting several strands of yarn side by side. The 20, 40, 60, etc. in front of the sewing thread model all refer to the count of the yarn. The count of the yarn can be simply understood as the thickness of the yarn. The finer; the 2 and 3 behind the model number respectively indicate that the sewing thread is made of several strands of yarn twisted together. For example: 603 is made of 3 strands of 60 yarns twisted together. Therefore, the sewing thread synthesized by twisting yarns with the same number of strands, the higher the count, the thinner the thread and the lower the strength; while the sewing thread twisted by the same number of yarns, the more strands, the thicker the thread and the stronger the strength. big.
Comparison of line thickness: 203>202>403>402>603>602
The line strength comparison is similar to the line thickness!
Generally speaking: 602 thread is mostly used for thin fabrics, such as silk, georgette, etc. in summer; 603 and 402 threads are basically universal and are the most common sewing threads, and can be used for general fabrics, such as cotton, linen, polyester, viscose, etc. Thread 403 is used for thicker fabrics, such as woolen fabrics, etc. Thread 202 and 203 can also be called denim threads. The threads are thicker and stronger, and are mostly used for sewing denim, bags, etc.
Main types and specifications of denim sewing thread
Based on the role of sewing thread in denim clothing is too great, and whether it is a good cow, an excellent denim jacket, or other denim products, sewing thread plays a very important role, and the durability of denim clothing is one of them. A major factor is also its tough sewing thread, and sewing thread is also very important in the decoration of denim clothing. Here, I will briefly introduce the types and specifications of sewing thread to you.
The sewing threads used for sewing mainly include two types of synthetic thermoplastic fibers, filament twisted and core-spun yarns, such as nylon and polyester, which have high toughness and wear resistance, and can be made better with cotton fibers. The greater ductility and lower moisture absorption of nylon and polyester make the sewing thread stronger, and the lower melting point makes the sewing thread more sensitive to the heat changes of the machine needle.
