How to choose the right sewing thread when sewing a jacket?
When choosing sewing thread, we need to consider multiple factors to ensure the durability, appearance and comfort of the jacket. Here are some key points to help you choose the most suitable sewing thread for Your Jacket.

Material of sewing thread
Sewing thread can be divided into three categories according to the raw materials: natural fiber, synthetic fiber sewing thread and mixed sewing thread. For clothing such as jackets that require high wear resistance and heat resistance, synthetic fiber or mixed sewing thread is usually a better choice.

Thickness of sewing thread
The thickness of sewing thread affects its strength and applicability. Common types of polyester thread are 20s/2, 20s/3, 30s/2, 30s/3, etc., among which 40s/2 is the most versatile. Jackets usually require thicker threads to withstand greater forces, so you can choose threads such as 30s/2 or 40s/2.

Performance matching of sewing thread
The performance of the sewing thread should match the fabric. Chemical fiber fabrics should use chemical fiber or blended sewing thread to ensure consistency in strength and shrinkage. For jackets, it is usually necessary to choose sewing threads that are wear-resistant, heat-resistant, and have a low shrinkage rate.

Consistency of color and texture
The color and texture of the sewing thread should be consistent with the jacket fabric. The color of the general sewing thread should be the same color or close to the color of the fabric to maintain the overall beauty

Sewing thread with special functions
For jackets with special functions, such as waterproof or fire-resistant jackets, it may be necessary to use sewing threads with special treatments, such as sewing threads with high temperature resistance, flame retardant or waterproof finishing

Strength and uniformity of sewing threads
Sewing threads must have a certain strength and strength uniformity to ensure the firmness of sewing. High-quality mercerized cotton thread is expensive, and cotton sewing thread is rarely used now, while short-fiber polyester sewing thread is low-cost and has excellent stitching stability, durability and sewing properties

Twist and softness of sewing threads
Sewing threads should be smooth and uniform in fineness, with moderate twist, soft, elastic, and without joints and thick sections. These characteristics help improve the quality and appearance of sewing.

Brand Recommendation
Some well-known brands such as Coats Threads are used as exclusive sewing threads by international first-line brands such as Prada and Chanel. The sewing threads of these brands are usually of high quality and trustworthy.

Conclusion
In summary, when choosing sewing threads for jackets, you should consider thread material, thickness, performance matching, consistency of color and texture, special functional requirements, strength and uniformity, twist and softness, and brand reputation. By combining these factors, you can choose the most suitable sewing thread for your jacket to ensure the durability, appearance and comfort of the jacket.

What is the difference between 30s/2 and 40s/2 thread

The main difference between 30s/2 and 40s/2 thread lies in their thickness and applicability. Here is a specific comparison:

Different thickness:
30s/2 thread is a double-ply thread made of 30-count yarn, while 40s/2 thread is a double-ply thread made of 40-count yarn. In sewing thread, the count (S) is a unit that indicates the thickness of the yarn. The higher the count, the thinner the yarn. Therefore, 40s/2 thread is thinner than 30s/2 thread.

Different applicability:
30s/2 thread is usually used for sewing thick fabrics, leather, sofas, bags and other products, with a wire diameter of about 0.25mm. This thickness of thread is suitable for bearing heavier sewing pressure and is suitable for thicker materials.
40s/2 thread is often used for household sewing, lightweight clothing and general clothing sewing, with a wire diameter of about 0.20mm. Because of its thinness, this thread is better suited for delicate sewing work, such as thin fabrics and fine stitching.

Different strength:
Because 30s/2 thread is made of thicker single yarns, it is usually stronger than 40s/2 thread with the same number of strands.

Appearance and feel:
Because 40s/2 thread is thinner, it can be better integrated into the fabric when sewing, reducing the wear and tear on the fabric, and it feels softer.
Because of its thicker diameter, 30s/2 thread feels relatively harder and is more suitable for occasions that require wear and tear resistance.
When choosing sewing thread, you need to decide whether to use 30s/2 or 40s/2 thread based on the thickness of the fabric, the strength requirements of the sewing project, and personal preference. For example, for a jacket that requires high wear and heat resistance, you may choose 30s/2 thread; while for thin fabrics that require delicate stitching, 40s/2 thread may be a better choice.

Does sewing thread for jackets need to be heat-resistant?

Whether sewing thread for jackets needs to be heat-resistant depends on the material of the jacket and the heat treatment that may be encountered during the sewing process. Here are some key points:

Heat resistance requirements: For jackets that need to be ironed at high temperatures, such as Cotton Jackets, heat resistance is an important consideration. Cotton sewing thread has high heat resistance and is suitable for high-speed sewing and durable pressing. Therefore, if the jacket fabric needs to be exposed to high temperatures during sewing or subsequent processing, it is necessary to choose heat-resistant sewing thread.

Material matching: The raw material of the sewing thread should be consistent or similar to the clothing material as much as possible to make its performance equivalent. Synthetic fiber clothing should use chemical fiber or blended sewing thread to ensure consistency in strength and shrinkage. For jacket fabrics that may involve high-temperature treatment, choosing sewing thread with excellent heat resistance can ensure that the thread will not melt or be damaged during the ironing process.

Specially treated sewing thread: For special functional clothing, such as high temperature resistant, flame retardant or waterproof finished clothing, specially treated sewing thread is required. This means that if the jacket has these special features, or requires special heat treatment during the production process, then heat-resistant sewing thread is necessary.

Heat resistance of polyester sewing thread: Polyester sewing thread has good heat resistance and can remain stable in high temperature environments. Therefore, for jackets that do not require extreme heat treatment, polyester thread may be a suitable choice.

Heat resistance of blended sewing thread: Polyester-cotton blended sewing thread is made of a blend of polyester staple fiber and cotton fiber, which has high strength, abrasion resistance and heat resistance, making it suitable for all types of clothing, including jackets that may require heat treatment.

In summary, if the production or maintenance process of the jacket involves high-temperature ironing or other heat treatment, choosing heat-resistant sewing thread is necessary. Heat-resistant sewing thread can ensure the durability and integrity of the jacket during these processes, avoiding melting or damage of the stitching.
