Terry pile socks are a type of sock- Zhejiang Yangshi Industry Co., Ltd

Terry pile socks are a type of sock that is used to reduce friction. It is constructed with two or three series of warp threads. This design produces terry fabric, which is a looped fabric with air pockets. The air pockets serve as an insulator and an absorption agent. They may be reversible or single-sided. These socks are low in density. However, they have a lower static friction than a flat constructed sock, and are able to absorb shear force better than conventional wool or acrylic socks.

There are many different types of terry fabric. Some of the most common are 3-pick, 4-pick, and 5-pick terry. These designs are designed to improve application performance, compression, and aesthetic appearance. Other designs include the 6-pick and the alternate single-side terry.

Terry woven fabric is produced with pile yarn containing a PVA fibre in the core of the yarn. This helps to reduce friction and bending rigidity, while also resulting in less tortuous capillaries. The yarn is typically woven with a cotton warp, which is then washed in warm water at 100 degrees C.

A study found that a terry pile sock could absorb moisture and shear forces better than a flat constructed sock. An experiment was conducted to evaluate the capacity of a simulated foot to absorb moisture and shear force. In this study, a simulated foot was fixed in place and loaded with a pressure equivalent to an adult sock. At the same time, the rate of moisture absorption was measured by weighing the sock at intervals.

The terry pile sock performed better than the conventional wool sock at absorbing moisture and shear forces. In fact, the sock reached 25% moisture capacity in a shorter time than the conventional sock, while approaching its maximum capacity more rapidly. Furthermore, the static friction of the terry pile was 10% lower than the corresponding sock.

While the terry loops may be single or double-sided, the underlying fabric is often made from a thin, layered wicking structure that is designed to maintain dryness within the shoe during exercise. It may be enhanced by slippery fibres or a high areal density.

Another design is a wrap yarn structure. This is designed to enhance terry fabric's performance, and is constructed with a wrap yarn of coarser and finer cotton yarns. Each warp is made up of two sets of threads, the ground and the wrap. As a result, the fibres in the wrap yarn core are almost parallel. Therefore, they help to increase the elasticity of the yarn and reduce the likelihood of shedding.

Lastly, there are reversible terry structures. These structures are usually single-sided but have terry loops on both sides. Double-sided terry is much more expensive but is known to perform better.

Ultimately, the best sock for your foot is the one that can effectively absorb moisture and shear forces, and still maintain its thickness. This is especially important for socks that are worn under impermeable footwear.
