The core difference between pure cotton sweaters and spandex sweaters is the fiber composition, which leads to significant differences in key properties such as hand feel, warmth, wearability, and difficulty of care. Pure cotton sweaters are made of 100% cotton fiber, while spandex sweaters is a mixed fabric of cotton fiber and spandex fiber, the specific difference is as follows:

I. Core components and essential positioning

Pure cotton sweater: The ingredients are 100% natural cotton fiber, belonging to natural plant fiber products, the core advantage is skin-friendly, breathable, environmentally mild, and suitable for people with high material sensitivity.

Acryl cotton sweater: is a cotton fibre mixed with acrylic fibre in a certain proportion (common proportion such as 70% cotton). + 30% acrylonitrile, 50% cotton + 50% acrylonitry, etc.), belongs to a combination of natural and synthetic fibers, and the core positioning is to balance the skin-feeling of pure cotton and the warmth and fluffyness of acrylonitril, while optimizing the shortcomings of pure wool such as deformation and wear resistance.

II. Critical performance differences

1. Touch and hand feel

Pure cotton sweater: the hand feels soft and gentle, has the delicate texture of natural cotton fiber, does not have a "plastic feel" when touching, and has high comfort to wear, especially for people with delicate skin. However, the pure sweater material is thick and heavy, has poor fluffyness and lacks elasticity.

Acrylic sweaters: They have both the softness of cotton and the fluffyness of acrylic, which is lighter and more elastic than pure cotton sweaters, and have a slight "warm texture" when touched (derived from the properties of aluminum); The higher the proportion of acrylic in the mixed textile ratio, the more noticeable the fluffy feeling, and the higher the ratio of cotton, the closer the delicateness of pure cotton.

2. Heat and breathability

Pure cotton sweater: It is extremely breathable, and the porous structure of the cotton fiber can quickly disperse sweat and avoid the sweltering feeling. However, the warmth is weak, the cotton fiber has poor thermal lockability, and the warmth will be further reduced after moisture absorption, which is more suitable for wearing as a thin model in spring and autumn.

Acrylic sweaters: The warmth is better than pure cotton sweaters, and the flexible structure of acrylic can lock the air to form a heat insulation layer, improving the cooling effect. The breathability is between pure cotton and pure acrylic, the higher the proportion of cotton, the better the breathability, and the higher that of acrylic is slightly worse, but the overall breathability is more than pure aluminum sweaters.

3. Wearability and durability

Pure cotton sweaters: medium wear resistance, poor wrinkle resistance, easy to deformation and wrinkle after wearing or washing for a long time, and may loose and harden the fabric after several washings. The intensity will decrease after smoking, and care should be taken.

Acrylic sweaters: The wearability is better than pure cotton sweaters, and the addition of acrylic improves the wear resistance and elastic recovery of the fabric, which is not easily deformed and wrinkled after washing. However, mixed fabrics may experience a slight puffing and balling (depending on the quality of the acrylic and the mixed fabric process), and the overall durability is more balanced.

4. Exterior and stability

Cotton sweater: soft luster, showing the matte texture of natural vegetable fibers, moderate degree of saturation, but the general color fastness, long-term exposure or repeated washing may fade; It is prone to shrinkage and deformation due to dampening or improper washing.

Acrylic sweaters: The gloss is slightly brighter than pure cotton sweaters, the color brightness is higher, the dye stability of acrylic is better, and the overall fading risk is lower than that of pure cotton. It is more resistant to shrinkage and deformation, and can better maintain the clothing in its original form after wearing and washing.

5. Washing & Care

Pure cotton sweaters: require gentle care. Hand washing or a "gentle step" of the washing machine is recommended. Water temperature is controlled below 30 ° C. Avoid rubbing hard (to prevent deformation);Do not dry at high temperature, otherwise it is easy to shrink and harden; After drying, it should be arranged in a timely manner, and when stored, avoid a humid environment (to prevent mold).

Nylon sweaters: The care difficulty is lower than pure cotton sweaters, can be machine washed (normally a gentle stroke) and the water temperature does not exceed 40 ° C;The resistance to high temperature is slightly stronger than pure cotton, but high temperature drying is still not recommended; The drying speed is faster than pure cotton, there is no need for special moisture protection when storing (acryl is better against mold than cotton), and the overall care is more mindless.

6. Price and applicable scenarios

Pure cotton sweaters: medium price, suitable for breathability requirements high, skin sensitive, or daily wear in spring and autumn (e.g. thin bottoming, thin outerwear); It is not suitable for humid and cold environments, and avoid losing heat due to damp absorption.

Nylon sweaters: the price range is broad (depending on the ratio of cotton to nylon and the quality of the raw material), The overall cost-effectiveness is higher than pure cotton sweaters, suitable for scenes where a certain amount of warmth is needed in winter and skin comfort is also sought (such as thick knits, winter bottoming), and also suitable to wear frequently on a daily basis (wearable and easy to handle).

III. Quickly distinguishing Small Tricks

Judging by hand: extremely soft and delicate, without a fluffy feeling, and the probability of being thick or heavy is pure cotton; Most of the products with a fluffy feel, better elasticity and lighter handfeel are acrylic cotton blend.

Burn test: Remove a small amount of fiber and burn. Pure cotton smells of paper burning when it burns, and the ash is a grey-white powder and disperses immediately when blown; When acrylic cotton mixed is burned, it has both a paper odor and a slight odor of plastic charred, and there are brittle pieces (acrylic residue) in the ashes, some of which can be crushed.

Resilience test: Gently pull the fabric. When you release it, it is a cotton sweater that recovers quickly and does not leave a trace. The slower recovery and prone to slight relaxation are pure cotton sweaters.
