The method of distinguishing pearl cotton coils in the industry is divided by density. The density of pearl cotton is the weight per cubic meter. Commonly used pearl cotton roll materials are divided into three types according to the structure: high density, medium density and low density. High-density porosity is very full, often used as sound-absorbing cotton, sofa cushions, soft bags, and other materials. Density is an important indicator of material. The higher the density of pearl cotton roll material, the smaller the voids and the higher the quality.
The hardness of pearl cotton is generally high, and the hardness of pearl cotton is also high. However, it is not excluded that some high-density pearl cotton rolls will add super soft additives to make the pearl cotton rolls super soft and used for sound absorption. Cotton, sofa cushion, soft bag material. Medium-density, low-density pearl cotton is used as a general protective material. The hardness of pearl cotton of the same density is also different.
做沙发坐垫的珍珠棉密度为左右，有软、硬、超软等规格。 Generally , the density of pearl cotton used for sofa cushion is about left and right, and there are specifications of soft, hard and super soft. The mattress is generally left and right. High-density pearl cotton is generally not used for water absorption.
