21s Cotton Yarn

21 strands of cotton yarn are pure cotton single yarns that are manufactured under the standards of either metric or imperial counting systems with specific twist and process. Their yarn count specifications represent the ideal balance point of neither being too thick nor too thin - they possess sufficient strength and volume while retaining the natural softness of cotton fibers. This classic count holds a core position in the global textile supply chain, serving as a crucial intermediate material that connects raw fiber materials with final fabrics. It is widely used in various fields ranging from daily wear to home life.

After multiple washes, ordinary cotton T-shirts tend to develop loose fibers and become dull. The mercerized and mercerized yarn undergoes high-temperature flame treatment, effectively removing the surface fuzz and making the fiber structure more compact and stable, thus completely eliminating the problem of balling. Even after long-term wearing, the clothes can still maintain a smooth and flat appearance, being both durable and visually appealing.
Bright colors with long-lasting color fixation
The mercerization process activates the cotton fibers, significantly enhancing their adsorption capacity for dyes. As a result, the color saturation is higher after dyeing, presenting a vivid and bright visual effect. At the same time, it has excellent color fastness (＞4 grades), and even after multiple washes, it is not prone to fading, maintaining its original bright color for a long time.
Stable shape, stylish to wear
Ordinary cotton fabrics tend to shrink, sag, and deform, causing the neckline to become loose and the shape to change. The mercerized and mercerized yarn undergoes professional tension control during processing, significantly reducing the shrinkage rate and improving the dimensional stability. The finished clothing can still maintain a fitting silhouette after repeated washing, always standing upright and stylish.

Balanced structural performance: 21 strands achieve the best balance between strength and fineness. The yarn structure is tight, making it less prone to fraying or breaking. This provides high through-put and low breakage rate for subsequent weaving, while also ensuring the durability and texture of the final fabric.
Excellent comfort and processability: It retains the excellent moisture absorption and breathability of cotton fibers, along with their skin-friendly properties. Its moderate thickness enables it to weave both delicate and smooth lightweight fabrics and also create textured patterns through process variations. It is also easy to undergo further processing such as dyeing, mercerizing, and scouring.
Wide industrial adaptability: As one of the industry standard counts, it has excellent compatibility with most knitting circular machines, jacquard looms, jet looms, etc., with high production efficiency. It is a reliable choice for textile factories to carry out multi-variety and rapid response production.

Knitted apparel sector: Used for making T-shirts, polo shirts, home wear, underwear and single-sided or double-sided fabric for some sweatshirts, focusing on comfort and shape.
Woven fabric sector: It is an important raw material for producing plain and twill fabrics for bedding, organza and chiffon for shirts, and denim and khaki for casual pants.
Home textiles and decoration sector: Widely used for manufacturing towels, bath towels, bed sheets, pillowcases, curtains and various home decorative fabrics, providing a soft touch and practical durability.
Industrial and supporting sector: Can be used for making gloves, medical base fabric, and eco-friendly bags for industrial textiles.
