How does sewing thread of down jacket affect the warmth effect: in-depth analysis from material to craftsmanship
Introduction
As a necessary warm clothing in winter, the warmth performance of down jacket depends not only on the quality of down, but also on the choice of sewing thread. This article will explore in depth the material, craftsmanship and influence of sewing thread on the warmth effect of down jacket, and provide practical suggestions to help you choose a better quality down jacket.
Warmth-keeping principle of down jacket
Warmth-keeping mechanism of down
Down stores a large amount of air through its fluffy structure. Air, as a poor conductor of heat, can effectively reduce heat loss and thus achieve warmth.
The role of sewing thread
Sewing thread plays an important role in fixing down, preventing leakage and maintaining the integrity of the overall structure in down jackets. If the quality of sewing thread is not good, it may cause leakage, excessive needle eye and other problems, thus affecting the warmth effect.
The influence of sewing thread material on warmth effect
Nylon thread and polyester thread
Nylon thread and polyester thread are widely used in the production of down jackets due to their high strength and wear resistance. These materials can withstand the tension during sewing, reduce the risk of thread breakage, and prevent down from leaking out of the needle holes.
Low friction and antistatic properties
High-quality sewing threads (such as Coats Epic AS and Gral AS) can effectively reduce the adsorption force between down and sewing threads by reducing friction and static electricity, thereby preventing down from leaking.
Effect of sewing thread technology on thermal insulation
Needle eye size and density
The thickness of the sewing needle and the size of the needle length directly affect the size of the needle eye. If the needle eye is too large, the down is easy to leak out of the needle hole, resulting in reduced thermal insulation performance.
Seam flatness
The flatness of the seam directly affects the warmth and comfort of the down jacket. High-quality sewing threads can make the seams smoother and reduce heat loss.
Orthogonal test and data analysis
The study shows that the number of quilting threads and the density of stitches are the key factors affecting the warmth of down jackets. Through orthogonal experiments, it was found that an increase in the number of quilting threads will reduce warmth, while an increase in stitch density will help improve warmth.
How to choose the right sewing thread
Brand recommendation
Sewing threads from brands such as Coats and A&E are widely used in the production of high-end down jackets due to their low friction, high strength and antistatic properties.
Material and process
Choosing sewing threads with low friction, antistatic and high strength properties can effectively prevent down leakage and improve the warmth of down jackets.
Conclusion
As a key link in the production of down jackets, sewing threads directly affect their warmth performance and service life. By selecting high-quality sewing threads and optimizing the sewing process, the warmth effect of down jackets can be significantly improved to meet the high standards of the international market.
