Production methods of imported dry-laid spunbond non-woven fabrics

With the growth of the economy, people’s demand for non-woven fabrics continues to increase, and my country’s non-woven fabric production has also developed rapidly, among which imported dry-laid spunbond non-woven fabrics are one of them.

Among the non-woven fabric manufacturing methods, the spunbond method has achieved remarkable rapid development in the past 20 years due to its obvious advantages in manufacturing technology, product performance and production efficiency.

About 40% to 50% of non-woven fabric production adopts melt spinning method (including spunbonding method, melt blowing method and composite method of the two). The total output of this melt spinning production method in various regions The proportions in the United States are 50%, Europe is 37%, and Japan is 41%. From the data, it can be seen that advanced countries use melt spinning as the main production method of non-woven fabrics.

Imported dry-laid spunbond non-woven fabric is a non-toxic, odorless and tasteless milky white highly crystalline polymer with a density of only 0.90–“0.91g/cm3. It is one of the lightest varieties of all plastics currently.

It is particularly stable in water, with a water absorption rate of only 0.01% and a molecular weight of about 80,000 to 150,000.

The formability is good, but due to the large shrinkage rate (1%~2.5%), thick-walled products are easy to dent, and it is difficult to meet the requirements for some parts with high dimensional accuracy, and the surface gloss of the product is good.
