Production process and structure of sock yarn

The manufacturing process and structure of yarns directly affect the look, feel and performance of socks.

1. Spinning process

* Ring Spinning: A traditional process that produces dense, strong yarn with a relatively rough feel. Commonly used for cotton socks.

* Air-spinning: A modern process with high yields, resulting in fluffy, soft, and wear-resistant yarn, but slightly lower strength. Often used to make the base yarn for terry socks.

* Tightly twisted yarn: High twist makes the yarn stronger and less prone to pilling, but it also makes the hand feel harder. It is often used in areas that require high wear resistance.

* Single yarn: The most basic form of yarn.

* Ply yarn: Two or more single yarns twisted together, making it stronger, less likely to tangle, and of higher quality.

* Core-spun yarn: A core of spandex is covered with cotton or other fibers. This retains the stretchiness of the spandex while retaining the feel and appearance of the outer fibers. This is the most common yarn used for high-end socks.

* Fancy yarn: including slub yarn, knot yarn, loop yarn, etc., used to create special visual effects and touch.
