Nonwoven geotextiles are made by imitation process
Introduction of Geotextile
Nonwoven geotextiles, a kind of polymer geotextiles, are usually divided into staple fibre bonded nonwoven geotextiles and polyester fibre bonded nonwoven geotextiles. They are commonly referred to as staple nonwovens and polyester nonwovens, alias staple cloth and polyester silk nonwovens.
Production process of staple and filament fabrics
The staple fabrics are made of polyester staple polyester or polypropylene fabrics, which are unpacked by the unpacking machine, loosened by the loosening machine, and then entered into the storage box. Then the compactness of the rolls is followed by four to five layers of mesh. Then, the staple fabrics are formed by laser cutting after four processes of pre-pricking, barb pricking and main pricking, while the filament fabrics are made of new polyester chip particles and processed by high temperature. Melting plasticization, wire drawing into a net, and then through the pre-piercing and re-piercing two needling processes, and finally trimming and stretching.
The difference between geotextiles and non-woven fabrics
Generally speaking, non-woven geotextiles refer to long (short) silk cloth, because the cloth is made by imitation cloth processing technology, so it is also called non-defensive cloth. However, non-woven geotextiles also include polyester woven fabrics (polyester machine woven fabrics) and barrel materials, because these two belong to the spinning fabric, so there is no special explanation that geotextiles are what we call non-woven fabrics. http://www.hnjyhg.com/
