Non-woven fabric is a kind of fabric that does not need to be woven and weaved. The woven short fibers or filaments are oriented or randomly arranged to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. .

So what is the effect of fiber properties on the properties of the nonwoven(Polypropylene Spunbond Nonwovens On Sales), and what are the effects? The following six points are for you:

(1) Fiber length: The fiber length is long, the product has high strength and good uniformity. However, the excessive length of the fiber is not conducive to combing, and it is easy to produce a fiber knot. Airlaid generally uses about 10 mm of fiber, and mechanical combing generally uses medium and long fibers of less than 65 mm.

(2) Linear density of fiber: The linear density is small, the strength of the product is high, and the uniformity is good. However, when the linear density is large, the fiber has good resilience.

(3) Curl degree of fiber: The degree of curl is insufficient, and the cohesion between fibers is poor, so that it is difficult to form a net, the uniformity of the web is poor, the strength is low, the hand of the nonwoven fabric(PP Non-woven Fabric Factory) is poor, and the elasticity is also poor.

(4) Cross-sectional shape of the fiber: the foreign fiber has a larger contact area than the fiber of the circular cross section, and has high strength, and the obtained nonwoven fabric(Polypropylene Non-woven Material Wholesale) has high strength.

(5) Friction coefficient of the fiber surface: the friction coefficient is large, the tangential resistance between the fibers is large, and the nonwoven fabric is high in strength. However, if the friction coefficient is too large, the puncture resistance will be increased, causing difficulty in acupuncture and causing needle breakage.

(6) Characteristics of the strength of the fiber: Generally speaking, the fiber is strong and the strength of the product is large.
