How to Control the Feel and Strength of Non - woven

Nonwovens are woven fabrics that do not require spinning and weaving, but simply staple or randomize the staple fibers or filaments to form a web structure that is then reinforced by mechanical, thermal or chemical means . Nonwovens break through the traditional textile principle, and has a short process, production speed, high yield, low cost, versatile, multi-source characteristics.
Non-woven soft and hard to do, is in the production process by controlling the temperature to achieve. The higher the temperature of the material on the more hard, low temperature of the material will play out the feel is relatively soft.
Soft material feel very soft close to the real knitted fabric, cloth toughness good tensile strength is not easy to tear, because the fabric will feel soft after the relatively thin. Hard material is the most common method of non-woven manufacturers.
Because the cloth to do the same weight after the fabric weight to compare the material to be much thicker, a lot of bad non-woven manufacturers to use this to cut corners, it is precisely because of this reason most manufacturers like to do hard material.
As the non-woven polypropylene is also produced, too hard after the show was relatively brittle, very bad pull, very prone to fracture.
