The application level of PP non-woven fabric can also be used as flower packaging cloth, luggage cloth, etc. The characteristics of wear resistance, firm hand feeling, etc. make it a good choice for making such products.

PP non-woven fabric refers to a non-woven fabric produced from polypropylene, that is, polypropylene. The non-woven fabric produced by this material is a commonly used PP spunbond non-woven fabric on the market. This non-woven fabric can be rich in color, bright and bright, fashionable and environmentally friendly, widely used, beautiful and generous, with various patterns and styles, and is lightweight, environmentally friendly and recyclable. It is internationally recognized as an environmentally friendly product that protects the earth's ecology.

Various common properties of PP non-woven fabrics!

(1) Physical properties

PP non-woven fabric is a non-toxic, odorless, milky white high-crystalline polymer. It is one of the lightest varieties of plastics at present. It is particularly stable to water. The water absorption rate in water for 14 hours is only 0.01%. The molecular weight is between 80,000 and 150,000, and the moldability is good. However, due to the large shrinkage rate, the original wall products are easy to dent, and the surface color of the products is good and easy to color.

(2) Mechanical properties

PP non-woven fabric has high cleanliness and regular structure, so it has excellent mechanical properties, and its strength, hardness and elasticity are higher than high-density PE. The outstanding feature is that it has strong resistance to bending fatigue, and the dry friction coefficient is similar to that of nylon, but it is not as good as nylon under oil lubrication.

(3) Thermal properties

PP non-woven fabric has good heat resistance, the melting point is 164-170 °C, and the product can be sterilized at temperatures above 100 °C. Under the action of no external force, it will not deform at 150 °C. The embrittlement temperature is -35 °C, and embrittlement occurs below -35 °C, and the heat resistance is not as good as PE.

(4) Chemical stability

PP non-woven fabric has good chemical stability. In addition to being eroded by acid, it is relatively stable to other chemical reagents, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc. can soften and swell PP non-woven fabric, and it is chemically stable. The performance also improved with the increase of cleanliness.

(5) Electrical properties

The non-woven fabric has excellent high-frequency insulation performance. Because it hardly absorbs water, the insulation performance is not affected by humidity, has a high dielectric coefficient, and can be used to make heated electrical insulation products with the rise of temperature. The breakdown voltage is also very high, suitable for electrical accessories and so on. It has good resistance to voltage and arc, but has high static electricity, and it is easy to age when it is in contact with copper.

(6) Weather resistance

Non-woven fabrics are very sensitive to ultraviolet rays, and the addition of zinc oxide dilauryl thiopropionate, carbon black-like milky white fillers, etc. can improve its aging resistance.
