Preventing construction cracks with needle-punched nonwovens

Needle punched non-woven fabric is a polyester fiber cloth, also known as geotextile, which is a water-permeable geosynthetic material made of synthetic fibers by needle punching or weaving.

Needle-punched non-woven fabric is a kind of fabric that does not require spinning and weaving. It is often used in construction and roof waterproofing as the base fabric. The exact name should be 'nonwovenBecause it is a kind of fabric that does not need spinning and weaving, it just orientates or randomly spun short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. Nonwovens break through the traditional textile principle, and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, and many sources of raw materials.

Industrial non-woven fabrics: filter materials, insulating materials, cement packaging bags, geotextiles, wrapping cloths, etc. Needle-punched non-woven fabric: mainly used in construction, roof waterproofing as the base fabric, with sand, cement, etc. on it, to prevent the sand from leaking. Needle-punched non-woven fabrics are often used in construction as a measure to prevent cracks.
