GENWISE YARN CO.,LTD.

Spandex (also known as Lycra) is the source of elasticity. Its core function is to make the socks fit tightly to the foot, not slip off, and maintain their original shape.

Combed cotton is made by adding a "combing" process to the ordinary spinning process to specifically remove shorter cotton fibers and impurities.

Advantages: Long, neat fibers remain. This results in smoother combed cotton yarn, resulting in a smoother, more delicate surface and a delicate feel. Stronger: Less prone to pilling. More durable: The fibers are more tightly bound together, resulting in greater strength. Therefore, combed cotton is the preferred material for high-quality cotton socks.

Not exactly, the number of stitches needs to match the type of socks.

High needle count (such as 168 needles or more): means the knitting is tighter, the socks are thinner, smoother and more delicate, and are suitable for formal socks and stockings.

Low needle count (such as less than 120 needles): means the knitting is looser, the socks are thicker, softer and fluffier, and are suitable for sports socks and towel-soled socks.

Conclusion: The needle count represents style and thickness, not absolute quality. A good pair of sports socks needs to be of appropriate thickness to provide cushioning, so they don't pursue extremely high needle counts.

Because 100% cotton yarn has no elasticity and poor abrasion resistance, it cannot meet the basic requirements of socks for fit and durability.

Mainstream classic formula: 78% cotton + 20% nylon + 2% spandex

Functional analysis:

Cotton: Provides moisture absorption, breath-ability, and soft skin-friendly feel.

Nylon: Provides extremely high strength and abrasion resistance and is the "skeleton" of the socks.

Spandex: Provides excellent elasticity and recovery, and is the "soul" of socks.

While cotton, wool, or a functional fiber (such as Coolmax) is spirally wrapped around the outer yarn. This method retains the excellent elasticity of the spandex core yarn while also possessing the feel and functionality of the outer fiber. The spandex is encased, preventing direct friction with the outside world and extending its elastic life. This also facilitates weaving and dyeing. Therefore, core-spun yarn is ideal for producing high-quality elastic hosiery yarn.

Within a certain range, higher twist levels create tighter inter-fiber bonds, resulting in stronger yarn and less pilling resistance. Excessively high twist levels can make the yarn stiffer, compromise the hand feel, and even cause the fabric to twist (torsion imbalance). Therefore, the twist level should be balanced based on the desired end product (e.g., whether a soft feel is desired).

A standardized technical specification sheet should be formed, including but not limited to:

Composition ratio: accurate percentage of each fiber (±1.5% tolerance).

Yarn count: such as Ne 32/2 ply, Ne 40, etc., indicates the thickness of the yarn.

Twist and twist direction: such as 800 twists/m, Z twist or S twist.

Elastic properties: spandex content, yarn breaking strength, and elongation at break.

Color fastness standards: clearly define the requirements for fastness levels such as wash-ability and friction resistance (such as reaching national standard level 4 or above).

Delivery form: Specifications and weight of bobbins (pagoda bobbins, conical bobbins).
