1. Basic characteristics of nylon thread and polyester thread
Basic characteristics of nylon thread
Nylon (Nylon), also known as polyamide fiber, is a high-strength and high-wear-resistant synthetic fiber. It has good impact resistance and low-temperature resistance, and can maintain good performance even in cold outdoor environments. Nylon thread has high strength, can withstand large tension, and is not easy to break, which makes it provide better durability and tear resistance when making down jackets.
Nylon thread has excellent wear resistance, which means that down jackets can better resist friction and wear for outdoor activities, thereby extending their service life. For example, in outdoor adventures, down jackets may come into contact with rough objects such as rocks and branches, and nylon fabrics can effectively resist the damage caused by these frictions.
Nylon thread also has good elasticity and recovery, and is not easy to deform, so that the down jacket can still maintain a good appearance and warmth performance after multiple wearing and washing. In addition, nylon feels smooth and has a high gloss, giving people a high-end feeling.
Basic characteristics of polyester thread
Polyester is a polyester fiber with good air permeability and moisture discharge. It can effectively discharge sweat and moisture generated by human activities and keep the body dry, which is very important for outdoor sports, especially in long-term high-intensity activities. Good air permeability can make the wearer more comfortable.
Polyester thread has strong UV resistance and is suitable for use in outdoor environments with strong sunlight. It can effectively prevent fabric fading and aging. It also has good acid and alkali resistance and strong tolerance to chemicals, which allows polyester fabrics to maintain a relatively stable state under various environmental conditions.
The polyester thread has good stiffness, and the down jacket made of it has a stiff appearance, texture, is not easy to wrinkle, and is easy to care for and wear. Moreover, the polyester fabric has high color brightness and rich and diverse colors, which can meet the appearance needs of different consumers.

2. Comparison of the performance of nylon thread and polyester thread in outdoor down jackets
Warmth performance
Generally speaking, the thermal insulation performance of nylon thread is relatively good. Because the surface of nylon fiber is relatively smooth, it can better reflect heat and reduce heat loss. At the same time, the fabric made of nylon thread has a high density, which can effectively block the cold air from the outside, thereby improving the thermal insulation effect of the down jacket. In the cold outdoor environment, nylon down jackets can better maintain the temperature of the human body and provide warm protection for the wearer.
The thermal insulation performance of polyester thread is also good, but it is slightly inferior to that of nylon thread. However, some specially treated polyester fabrics, such as composite fabrics with high-density weaving or added thermal insulation materials, can also improve the thermal insulation performance to a certain extent and achieve better thermal insulation effect.
Waterproof and windproof performance
Nylon thread has good windproof performance, and its tight weaving method can effectively block the invasion of cold wind, making the wearer feel warm and comfortable outdoors. In terms of waterproofing, although nylon itself has average waterproofing performance, by adopting special coating or lamination technology, such as adding DWR (durable water repellent) coating, its waterproofing ability can be significantly improved, so that nylon down jackets have good windproof and waterproofing performance and can cope with various adverse weather conditions.
Polyester thread also performs well in waterproofing and windproofing. The surface of polyester fabric is smooth and has a certain waterproof effect, and its waterproofing performance can be further enhanced by waterproofing treatment. In terms of windproofing, high-density polyester fabric can also effectively resist cold wind and prevent cold wind from entering the inside of the clothes. For example, some outdoor brands of polyester down jackets use advanced waterproof and windproof technology, which can keep the inside dry and warm when worn outdoors.
Breathable performance
Polyester thread has good breathability, which enables it to effectively discharge moisture and sweat generated by the human body during outdoor activities, keep the body dry, and avoid discomfort and body temperature drop caused by moisture. Especially in some high-intensity outdoor sports, such as mountaineering and skiing, good breathability allows the wearer to move more comfortably and freely.
The air permeability of nylon thread is relatively weak, but after special processing, such as using breathable membrane technology or adding breathable fibers to the fabric, its air permeability can be improved to a certain extent to meet the basic needs of outdoor activities.
Wear resistance
Nylon thread is known for its high strength and high wear resistance. In the fabric of outdoor down jackets, the wear resistance of nylon thread enables it to better resist friction and wear. In some parts that are prone to friction, such as cuffs, elbows and backs, nylon fabrics can provide longer-term protection, reduce fabric damage and leakage caused by wear, and extend the service life of down jackets.
The wear resistance of polyester thread is also good, but it is slightly worse than that of nylon thread. However, polyester thread has a higher tear resistance and can better resist tearing when facing external force pulling, thereby ensuring the integrity and warmth of the down jacket.
Lightness
Down jackets made of nylon thread are usually lighter, which is mainly due to the lightweight characteristics of nylon fibers. Lightweight down jackets are very important for outdoor activities. They will not bring too much burden to the wearer, making them more flexible and free in activities. For example, during long hiking or mountaineering, lightweight nylon down jackets can allow the wearer to save physical energy and improve activity efficiency.
The density of polyester thread is relatively large, and the down jackets made of it may be slightly thicker, but with the continuous advancement of textile technology, some new polyester fabrics have gradually reduced weight while maintaining good performance. When choosing outdoor down jackets, if lightness is the primary consideration, then nylon thread down jackets may have more advantages.

3. Applicable scenarios of nylon thread and polyester thread outdoor down jackets
Applicable scenarios of nylon thread outdoor down jackets
Nylon thread outdoor down jackets are very suitable for wearing in cold, windy and humid environments, such as mountains, polar regions, cold northern regions, etc., due to their excellent windproof and waterproof performance and warmth retention. For those who often participate in outdoor activities such as skiing, mountaineering, camping, etc., nylon thread down jackets are an ideal choice. They can effectively resist bad weather and provide warm and comfortable protection.
Due to the good wear resistance and tear resistance of nylon thread, nylon down jackets are also suitable for use in some more difficult outdoor environments, such as crossing the jungle, rock climbing and other activities, which can better resist the wear and tear of branches, rocks and other clothing.
Applicable scenarios of polyester thread outdoor down jackets
The breathability and UV resistance of polyester thread outdoor down jackets make them more suitable for use in some milder climates or long-term outdoor activities, such as daily outdoor leisure and travel. In these scenarios, good breathability can keep the wearer dry and avoid discomfort caused by sweating.
For some consumers who have high requirements for the appearance and color of clothing, the crispness and rich color selection of polyester thread down jackets also make it a good choice. For example, in short hikes around the city or daily commuting, wearing a stylish and colorful polyester thread down jacket is both warm and beautiful.
