How to tell the difference between recycled polyester staple fiber and wool

Characteristics of wool and recycled polyester staple fiber. Wool is slippery, hard and soft. Let's take a look at the characteristics of recycled polyester staple fiber.

recycled polyester staple fiber is one of the most widely used chemical fiber clothing fabrics in daily life. Its biggest advantage is that it has good wrinkle resistance and shape retention, so it is suitable for making outerwear. Generally, recycled polyester staple fiber fabrics have the following characteristics:

1, Polyester fabric has high strength and elastic resilience. Therefore, it is fast and durable, anti-wrinkle and non-ironing.

2, recycled polyester staple fiber fabric has poor hygroscopic property, makes wearers feel stuffy, and is easy to carry static electricity, stain dust, affecting beauty and comfort. However, it is easy to dry after washing, and the wet strength hardly decreases, no deformation, and has good washable performance.

3, recycled polyester staple fiber is a good heat-resistant fabric in synthetic fiber fabrics. It is thermoplastic and can be made into pleated skirts with long-lasting pleats. At the same time, the melt resistance of polyester fabric is poor, and it is easy to form holes when it meets soot and Mars. Therefore, wear should try to avoid the contact of cigarette butts, sparks, etc.

4, polyester fabric has better light resistance, in addition to worse than acrylic, its sun resistance is better than natural fiber fabric. Especially in the glass behind the sun resistance is very good, almost equal to acrylic fiber.

5, recycled polyester staple fiber has good resistance to various chemicals. Acid, alkali to its degree of damage is not large, while not afraid of mold, not afraid of moth.

The difference between wool and recycled polyester staple fiber:

1, the luster is different, pure wool fabrics are mostly soft and natural, less colorful; recycled polyester staple fiber wool-like fabric is rich and bright in color. If you look closely in the sun, you will often see dazzling points of light.

2, feel and elasticity is different. Pure wool fabric feel soft, fine and smooth, with bones, with the hand grip fabric or shake a shake with the hand, with a sense of vitality, slightly live wrinkle but not hard, soft rebound but not straight. Although recycled polyester staple fiber resembles wool in appearance, it has soft and smooth feel, no bones, many folds and slow rebound.

3, Burn it after drawing. After the pure wool fabric is drawn and rolled, it can be seen that the wool fiber is uneven in thickness, different in length and natural crimp; recycled polyester staple fiber and recycled polyester staple fiber are uniform in length and thickness.

After the pure hair burns, the fire burns slowly, leaving the flame to continue to burn, accompanied by the smell of burning hair, more ash, black crisp block, with the hand twist into powder. recycled polyester staple fiber is wool-like and burns quickly when it is close to the flame. The flame is yellow with the smell of burning paper. The ash contains white light ash that is easily dispersed and leaves hard pieces that are easily broken.
