Cotton fabric has become one of the most commonly used fabrics with excellent wearability, and is widely used in clothing fabrics, decorative fabrics and industrial fabrics. With the in-depth development of textile printing and dyeing, the variety of cotton fabrics is becoming more and more abundant, and the appearance, performance and grade are also continuously improved.
Due to the development of chemical fibers, cotton-type chemical fibers appeared, whose length (usually about 38 mm) and other physical properties meet the requirements of cotton spinning technology. They are purely spun or blended with cotton fibers on cotton spinning equipment. The fabrics of this type of fiber and cotton The fabrics are collectively referred to as cotton fabrics.
Main features
Cotton fabrics are inexpensive and have a wide range of applications. They are better underwear, baby wear and summer fabrics, and are also popular spring and autumn outerwear fabrics. The main characteristics of cotton fabric are:
(1) It has good moisture absorption and air permeability, and is comfortable to wear;
(2) Soft hand feeling, soft luster and rustic;
(3) Good warmth retention and excellent wearing performance;
(4) Good dyeability, bright color, complete color spectrum, but not good color fastness;
(5) Alkali and acid resistance. The concentrated alkali treatment can make the fiber section of the fabric round, thereby improving the luster of the fabric, that is, the mercerizing effect
(6) The light fastness is good, but long-term exposure to the sun will cause fading and strength reduction;
(7) Poor elasticity, easy to produce wrinkles and creases are not easy to recover;
(8) Pure cotton fabric is easy to mold and deteriorate, but it is resistant to insects.
Cotton fabric, also called cotton cloth, refers to cloth made of cotton fiber.
Cotton fabric has strong water absorption, abrasion resistance and washability, soft and comfortable, good warmth in winter, breathable and cool in summer, cotton fabric has become one of the most commonly used children's clothing materials due to its excellent wearing performance, and is the most popular children's clothing fabric. But its elasticity is poor, the shrinkage rate is large, and it is easy to wrinkle. Cotton fabrics are generally brighter in color and are mostly used in children's summer clothes, casual wear, underwear, sportswear, etc.
Wool is a highly regarded natural animal fibre which has been used since ancient times.
The reasons for its varied usages are to be found in the peculiar characteristics of the fibres. Wool is very elastic, resistant, heat retentive and capable of absorbing moisture, as well as promoting natural perspiration. These properties give the final fabric unique characteristics, whilst preserving its natural feel.
Most of the wool fibres are obtained by shearing the fleece of sheep, goats and members of the camelid family.
(1)Crimps: Wool fibre is wavy and twisted in some places. Crimp is the name for this waviness. The finer the yarn, the more crimps it will get.
(2)Friction softens the wool fibre, particularly when wet, and is thus beneficial in maintaining a smooth, soft texture in fabrics.
(3)The heat has little impact at low temperatures, but high temperatures weaken the fibre and cause it to lose its colour.
(4)Moisture effect: Wool is the most hygroscopic material on the planet. It can absorb up to 50% of its weight and bear up to 20% of its weight without getting drenched.
(5)When wool fibres are exposed to heat, moisture, and strain, they interlock and contract. Felting is aided by the scale-like exterior of the fibres.
(6)Heat conductivity: Since wool fibre is a weak conductor of heat, fabrics made from it are best suited for winter wear.
(7)Wool is highly durable, and when hung after being wrinkled or formed, it returns to its original form.
(8)It has more strength than silk. Wool loses about 25% of its strength when wet. The yarn's strength will increase as the fibre lengthens.
(9)Wool is a highly elastic material. When it's dry, it's about 10% to 30% stretched, and when it's wet, it's about 40% to 50% stretched. When it's dry, it quickly returns to its original measurements.
(10)Wool has a high resistance to shrinkage. Long-term moisture exposure, on the other hand, can cause shrinkage.
That’s like asking, ”Which is better, a screwdriver or a hammer?” For some situations, wool is better, and for some, cotton is the top choice. In some cases, there’s no clear answer—and sometimes, a blend is best.
Which is warmer? Wool. No contest here: Wool is one of nature’s standout insulators.
Which is cooler? Cotton. Light cotton fabrics can be incredibly cool on a hot day (think a seersucker shirt in summer). But merino wool is a popular performance material for warm weather because it wicks perspiration away from the skin.
Which is better when wet? Wool. It’s nature’s best insulator in wet conditions, whereas wet cotton can become a saggy, clammy liability. Notably, cotton is stronger wet than dry, whereas wool is weaker when wet.
Which is more expensive? Wool. Usually by a lot.
Which is stronger? Cotton…kind of. Cotton fibers are stronger than wool fibers. But the overall strength of a fabric depends on how it’s made, not just what it’s made of: The sturdy fabric of a wool suit jacket is stronger than a gauzy cotton mesh.
Which is more eco-friendly? Draw. Both are natural, biodegradable fabrics, produced from renewable resources. But in terms of ecological impacts, it’s an apples-to-oranges comparison. Wool produces more greenhouse gasses, while conventionally grown cotton takes lots of water and pesticides.
