In the production of hot-air bonding, it is mostly necessary to mix a proportion of low-melting bonding fibers in the web or use bi-component fibers, or a powder-spreading device to apply an amount of bonding powder before the web enters the drying room. Maintain the original properties of the fiber. Generally, products made by hot-air bonding have the characteristics of fluffy, softness, good elasticity, and strong warmth retention, but their strength is low and they are easy to deform.
The heating temperature of hot air bonding is generally lower than the melting point of the main fiber. The melting point of the powder is lower than the melting point of the fiber, and it will melt quickly after being heated, so that the fiber will be bonded into a single-layer double-curtain drying room hot air bonding production line schematic diagram. Therefore, in the selection of fibers, it is necessary to consider the matching of the thermal properties of the main fiber and the bonding fiber, and make the melting point of the bonding fiber and the melting point of the main fiber as large as possible, so as to reduce Airlaid Paper the heat shrinkage rate of the main fiber as much as possible.The origin of hot-rolled hot-air non-woven fabrics
With the rapid development of modern technology, more and more high-tech projects are used in production and use. Let us understand the origin of hot-rolled hot-air non-woven fabrics.. Hot-rolled hot-air non-woven fabrics are all high-tech development products. Hot-rolled hot-air non-woven fabrics have indispensable components in today’s development, and some friends are also using them, but they don’t know the origin of hot-rolled hot-air non-woven fabrics, and they will be puzzled in choosing and using them.
Hot-air bonding refers to the production method that uses hot air to penetrate the fiber web on the drying equipment to be heated and melted to produce bonding. When you come into contact with such products in the future, you can choose the right one to better play the role of the product. I must have read the introduction of this article, and also have an understanding of the origin of hot-rolled hot-air non-woven fabrics. The heating method used is unreasonable, and the performance and style of the products are also different. They not only improve the quality assurance of non-woven fabric processing and production, but also improve the benefit and efficiency of the overall application |
