Sprayed cotton, also known as sprayed cotton, is a non-woven fabric. The principle of the formation of the spray cotton structure is to spray adhesive on both sides of the fluffy fiber layer. Due to the certain pressure during spraying and the suction force during vacuum suction, the adhesive can also penetrate into the inside of the fiber layer. After spraying the adhesive, the fiber layer is dried and solidified, so that the junction points between the fibers are bonded, and the fibers that are not bonded to each other still have a considerable degree of freedom. At the same time, there are still many air voids in the three-dimensional network structure. Therefore, the fiber layer has a porous, high-fluffy warmth preservation function.

Sprayed cotton, also known as sprayed cotton, is a kind of non-woven fabric, usually called space cotton or vacuum cotton, which is made of natural cotton fiber, man-made fiber or synthetic fiber after being stretched, carded, sprayed, baked and cured. Because of its fluffy, high compression resilience, resistance to dry and wet washing, light weight, and warmth, in recent years it has become an important material for processing bedding such as quilts, ski shirts, space suits, quilts, sleeping bags, and some industrial products.

The reason for keeping warm.

Because the spray cotton is sprayed, not under the dipping condition, the binder is added, and after spraying, it is no longer pressed and squeezed to solidify and shape. Therefore, in the bonded state of the fibers, there are more contact points at the intersections, and less bridging and agglomeration of the adhesive. This is the main reason why the spray cotton can keep soft and keep warm.

According to the formation principle of the spray cotton structure, in order to obtain excellent physical and mechanical properties, the choice of fiber raw materials and adhesives and the production process should be studied and selected. The choice of fiber raw materials is more important.

The types and specifications of fiber raw materials play a decisive role in the quality of spray cotton products. According to the application requirements of spray cotton, in order to keep warm, fluffy, and feel soft, the fiber degree, length, crimp degree, cross-sectional shape and surface treatment state of the fiber should be selected.

Glue-sprayed cotton is a pure polyester fiber, synthesized by carding, glue-spraying, and ironing processes. It has the characteristics of warmth, tensile strength, resilience, moisture resistance, and washing resistance. It is fluffy, soft, flat and firm.
