What Material Is Spray Glue Cotton? Comprehensive Analysis
When you buy pillows, cushions or cotton clothes, have you ever wondered what the filling is? Spray bonded cotton, as a widely used filling material in modern home furnishings and clothing, is gaining more and more consumers' favor due to its excellent performance.
What material is spray-bonded cotton? Basic composition and characteristics
Spray-bonded cotton, also known as spray-bonded cotton, is a kind of non-woven fabric, and is often called space cotton or vacuum cotton in the market. It is mainly made of three types of fibers: natural cotton fiber, man-made fiber or synthetic fiber. These raw materials are processed through a series of processes such as professional loosening, combing, spraying and baking and curing.
From the perspective of material composition, the structural formation principle of spray-bonded cotton is to spray the adhesive on both sides of the fluffy fiber layer. During the spraying process, due to the existence of a certain pressure and the suction force of the lower vacuum absorption, the adhesive can penetrate into the fiber layer. After drying and curing, the intersections between the fibers are bonded, while the fibers that are not bonded to each other still maintain a large degree of freedom.
The three-dimensional mesh structure of spray-bonded cotton retains many air gaps, which is the key to its porosity and high fluffiness. It is this unique structure that gives spray-bonded cotton excellent thermal insulation performance, making it an ideal filling material.
In practical applications, spray-bonded cotton usually appears in specific specifications. The gram weight of spray-bonded cotton on the market ranges from 40g/m² to 500g/m², the width can be between 0.5m and 3.2m, and the thickness ranges from 0.5cm to 5cm. This diverse specification enables it to meet the needs of different products, providing professional manufacturers such as KORONETA with a broad space for product development.
It is worth noting that the reason why the spray-bonded cotton can maintain its softness and good warmth retention is mainly because it adds adhesive under spraying conditions rather than impregnation conditions, and solidifies and forms without pressure extrusion after spraying. This makes the fiber bonding state mostly contact at cross points, and less agglomeration caused by adhesive bridges, thus maintaining the softness and elasticity of the material.
What is the production process of spray-bonded cotton?
The production of spray-bonded cotton is a precise and complex process that requires professional production lines and strict process control. A complete spray-bonded cotton production line usually includes the following processes: bag opening-opening machine-vibrating cotton feeder-carding machine-laying machine-oven-edge trimming and rolling machine.
Let's take a closer look at this production process, which is also the standard process adopted by professional manufacturers such as KORONETA:
- Bag opening stage: First, use a bag opening machine to open various bales of fibers, and weigh them according to the proportion by an electronic scale, and evenly lay them on the mixed cotton curtain. This step ensures the uniform mixing of the raw materials and lays the foundation for subsequent processing.
- Opening treatment: Different fibers are placed in the horizontal conveyor curtain, fed by the cotton pressing roller and the roller roller, and then opened by the high-speed beater and sent to the next process by the cotton conveying fan. The opening process makes the fibers fully separated to avoid agglomeration.
- Vibration feeding: The vibrating cotton feeder further loosens and mixes the opened fibers, and processes them into uniform mat cotton for the next process. This step adopts volumetric quantitative feeding and photoelectric control to ensure accurate and uniform cotton feeding and improve product consistency.
- Combing processing: The carding machine is usually a single cylinder, double doffer, four messes, and roller stripping structure. These rollers are finely processed after tempering and qualitative treatment, and are equipped with a suction device to reduce the number of machine cleaning times. They have the advantages of strong combing ability and high output.
- Web laying processing: The web laying machine evenly lays the cotton web on the bottom curtain according to the required unit weight for the next process. This step determines the thickness and uniformity of the spray-bonded cotton.
- Drying room treatment: The drying room heats the product evenly through high temperature. It generally adopts a three-layer conveyor belt structure with a spray tank for even spraying. The drying and curing process allows the adhesive to firmly bond the fibers at the intersection.
- Trimming and rolling: Finally, the trimming and rolling machine cuts the finished product longitudinally and transversely to form the final product specifications. This step ensures that the product size is accurate and convenient for subsequent applications.
In the production process, the selection of fiber raw materials is a key factor in determining the quality of spray-bonded cotton. In order to produce spray-bonded cotton with good warmth retention, good fluffiness and soft feel, it is necessary to carefully select parameters such as fiber fineness, length, curl, cross-sectional shape and surface treatment status.
The most commonly used is hollow spiral curled polyester fiber, which is usually 6.6~7.7 dtex (dtex) and 51~76 mm in length. This specification of fiber has good comprehensive performance and will not produce a too soft or too rough feel. It is particularly suitable for KORONETA pillows, cushions and dolls.

What are the advantages of spray-bonded cotton?
As a modern filling material, spray-bonded cotton has a variety of impressive advantages that make it stand out in many application areas, especially in products from professional manufacturers such as KORONETA.
