The principle of using sewing thread

Although sewing thread does not look very conspicuous, its selection and use cannot be ignored. When we hold a pure white garment with black sewing thread, do we feel a little strange and affect the appearance? Therefore, the selection and use of sewing threads are still very principled. Let’s take a look at how to choose!

The comprehensive index for evaluating the quality of sewing thread is sewability. Sewingability refers to the ability of a sewing thread to sew smoothly and form a good stitch under specified conditions, and maintain certain mechanical properties in the stitch. The pros and cons of sewability will have a direct impact on garment production efficiency, sewing quality and wearing performance. According to the national standards, the grades of sewing threads are divided into first-class, second-class and foreign-class products. In order to make the sewing thread have the best sewability in garment processing and the sewing effect is satisfactory, it is very important to select and apply the sewing thread correctly. The correct application of sewing thread should follow the following principles:

(1) Compatible with the characteristics of the fabric: the raw materials of the sewing thread and the fabric are the same or similar, so as to ensure the uniformity of its shrinkage rate, heat resistance, wear resistance, durability, etc., and avoid the appearance shrinkage caused by the difference between the thread and the fabric.

(2) Consistent with the type of clothing: For special-purpose clothing, special-purpose sewing thread should be considered, such as elastic sewing thread for elastic clothing, and heat-resistant, flame-retardant and waterproof sewing thread for fire-fighting clothing.

(3) Coordinate with the stitch shape: the stitches used in different parts of the garment are different, and the sewing thread should also be changed accordingly. Seam and shoulder seams should be firm, while buttonholes should be wear-resistant.

⑷ Unify with quality and price: The quality and price of sewing thread should be unified with the grade of clothing. High-grade clothing should use high-quality and high-priced sewing thread, and medium and low-grade clothing should use ordinary quality and moderately priced sewing thread. Generally, the label of sewing thread is marked with the grade of sewing thread, the raw material used, the fineness of yarn count, etc., which helps us to choose and use sewing thread reasonably. Sewing thread labels usually include four items (in order): yarn thickness, color, raw materials, and processing methods.

The above is a brief introduction to the selection principle of sewing thread, I hope it will be helpful to everyone.
