Pure wool refers to knitted sweaters with a wool content of 100%, made from sheep wool. It is a classic representative of natural knitted fabrics and the mainstream material for mid to high end sweaters.

Core advantages

Warm and breathable, comfortable to the body

Wool fiber has a natural curled structure that can lock in a large amount of static air, providing much better warmth than synthetic materials of the same thickness; At the same time, the fiber has moisture absorption and breathability, which can absorb about 30% of its own weight of water vapor. After sweating, it slowly releases and is not easy to sweat and stick to the body. It is dry and comfortable to wear in autumn and winter.

High quality texture, hanging and stylish

Natural wool fabric comes with a soft luster and a full drape, giving the upper body a textured feel and not easily appearing cheap like synthetic fabrics; The shape is firm and not soft, and it can hold up the aura for daily commuting and workplace dressing.

Natural and environmentally friendly, free from static electricity troubles

Natural animal fibers are not prone to static electricity, and wearing them in autumn and winter will not cause static electricity problems such as sticking to the legs, absorbing dust, or cracking; It can be naturally degraded and is more in line with the concept of green environmental protection compared to synthetic fibers.

Rich segmented categories, suitable for diverse needs

From ordinary sheep wool to Merino wool and sheep wool, pure wool has a perfect gradient: coarse wool is durable and practical, fine Merino wool is skin friendly and can fit snugly, and sheep wool is soft, sticky, and fluffy, which can meet the needs of different hand feel and price points.

Main disadvantages

High nursing threshold, prone to shrinkage and deformation

Wool fibers are prone to shrinkage and felting when subjected to high temperatures and vigorous rubbing. They must be hand washed or machine washed with wool gear, and cannot be soaked in hot water or vigorously wrung dry. Maintenance is far less worry free than synthetic fibers; Improper care can easily cause shrinkage and deformation after just one season of wearing.

Friction prone to pilling, average durability

The exposed ends of natural hair fibers can easily form hairballs after daily friction, especially in areas such as armpits and cuffs; Fiber toughness is weaker than synthetic fibers, and it is prone to wear and tear due to long-term pulling and friction. Its service life is slightly shorter than that of high proportion blended fabrics.

The price is on the high side, and the coarse version fits snugly against the skin

The cost of pure wool raw materials is much higher than that of synthetic fibers, and the selling price is generally higher; Ordinary coarse pure wool will have a noticeable pricking sensation when worn close to the body, and sensitive skin cannot be directly worn close to the body, requiring an inner layer as a base.

High storage requirements, susceptible to insect infestation

Long term storage requires the placement of insect repellents and keeping them dry, otherwise they are prone to insect infestation, and the cost of storage and maintenance is higher than that of synthetic fibers and blends.
