An in-depth guide for brand owners and wholesalers to optimize sock production equipment.
Introduction
The choice of machinery in sock production is crucial in determining the performance, quality, and market reception of the final product. For brand owners and wholesalers, understanding the characteristics and applications of different types of sock machines is key to enhancing production efficiency, maintaining product quality, and adapting to market demands.
One essential technical parameter of sock machines is the needle count, which determines the fineness of the fabric and the detail of the patterns—much like the “pixels” of an image. A higher needle count produces finer fabrics and more intricate patterns. Selecting the right sock machine is not only about improving productivity but also about ensuring competitiveness in diverse markets.
This article provides a detailed analysis of various sock machines to help brand owners and wholesalers better understand the relationship between different types of machines and their products. The goal is to make informed decisions about production equipment in response to complex market demands.
Types of Sock Machines
1. Circular Knitting Machines
-
- Definition: Circular knitting machines use cylindrical needle beds for knitting and are the most common type of sock machines.
-
- Applications: Widely used for producing standard socks, sports socks, and functional socks, these machines are ideal for large-scale production with high efficiency to meet mass-market demands.
Circular machines are divided into single-cylinder and double-cylinder types:
-
- Single-cylinder machines are further classified into fine gauge and coarse gauge, with the following subcategories:
-
- Plain fine gauge: Needle counts include 96N, 108N, 120N, 144N, 168N, 176N,188N, 200N, 220N, 240N. Common counts are 120N, 144N, 168N and 200N.
-
- Terry fine gauge: Common counts are 96N, 108N, 120N, 132N, 144N, 168N,176N and 200N, Common counts are 108N, 132N, 144N. with options for regular. (PS:Arbitrary terry designs machine 144N, 168N, 200N.)
-
- Single-cylinder machines are further classified into fine gauge and coarse gauge, with the following subcategories:
-
- Double-cylinder machines are divided into:
-
- Fine gauge plain (120N, 144N, 168N.) and Terry.(Have not appeared now.)
-
- Coarse gauge plain(56N, 84N,96N.) and Terry. (84N, 96N.)
-
- Double-cylinder machines are divided into:
2. Flat Knitting Machines
-
- Definition: These machines use a flat needle bed to produce intricate patterns and structures.
-
- Applications: Commonly used for sports shoe uppers, mesh designs, and high-value-added socks, flat knitting machines are ideal for customers seeking unique designs and high customization.

******Key Difference Between Double-Cylinder and Single-Cylinder Machines******
The primary distinction between double-cylinder machines and single-cylinder machines lies in their design and capabilities, particularly in pattern production and internal structure. In single-cylinder machines, jacquard designs (patterns) result in loose threads inside the sock. These loose threads are a natural byproduct of the machine’s design, where yarns are carried across the internal surface to create intricate patterns on the outer surface. This can sometimes cause issues such as reduced comfort or snags during wear.
In contrast, double-cylinder machines produce socks with a seamless interior and exterior. This is achieved by knitting on two separate cylinders, ensuring that the inner surface mirrors the outer one, eliminating loose threads entirely. However, the capability of double-cylinder machines to produce jacquard patterns is limited. For double-cylinder jacquard designs, the machine must use a double-cylinder double-feed mechanism, which adds complexity to the knitting process. Even with this setup, the color options for patterns are usually more limited compared to single-cylinder jacquard production.
Additionally, single-cylinder machines cut the yarn on the interior after completing a jacquard pattern, creating a cleaner appearance. In double-cylinder machines with double-feed jacquard capabilities, the yarn is not cut internally, leaving the interior intact. For more detailed visual insights into these differences, refer to accompanying photos.
