The Memis Acar study of the Department of Mechanical Engineering of Loughborough University in the United Kingdom proved that the spunlace process can process glass fibers and produce industrial fabrics. Because glass fibers are not crimped, traditional concepts believe that dry-laid nonwovens are difficult to process.
Most glass fiber nonwovens are generally processed by needle punching or wet processes, but North Carolina State University (NCSU) has successfully developed spunlace nonwovens blended with glass fiber and polyester. Thick-denier glass fiber with a diameter of 16um is difficult to process with spunlace method. If mixed with a fine-denier glass fiber with a diameter of 6.5um, it will help increase the strength of the spunlace nonwoven fabric.
Therefore, glass fibers of different deniers are mixed and fine-denier fibers are mixed. Conducive to spunlace, thick denier fiber is beneficial to increase the strength of spunlace nonwovens. If glass fiber is mixed with textile staple fibers such as polyester, the spunlace entanglement ability can be enhanced. Mixing glass fiber with low melting point polyester can produce glass native reinforced polyester composite material.
