Sanitray Nonwoven Fabric Strength And Hardness

Yiwu Guanghong Non-Woven Co.,Ltd | Updated: Jul 07, 2017

Physical properties: PP non-woven non-toxic, Sanitray Nonwoven Fabric tasteless milky white high crystalline polymer, is currently the most light of all varieties of plastic one of the water is particularly stable in the water 14h water absorption is only 0.01%. Molecular weight of about 8 to 150,000, Sanitray Nonwoven Fabric good shape. But the shrinkage rate, the original wall products easy to depression, the product surface gloss is good, easy to color.

(2) mechanical properties: PP non-woven fabric of high crystallinity, structured, and thus has excellent mechanical properties, its strength and hardness, Sanitray Nonwoven Fabric flexibility than high-density PE (HDPE) high. Highly characterized by bending fatigue (7 × 10 ^ 7) times the opening and closing of the folding bend without damage traces, dry friction coefficient and nylon similar, but not as good as nylon in the oil lubrication.

(3) thermal properties: PP non-woven fabrics with good heat resistance, the melting point of 164 ~ 170 ℃, the product can be 100 ℃ above the temperature sterilization. Sanitray Nonwoven Fabric In the absence of external force, 150 ℃ is not deformed. Brittle temperature of -35 ℃, below -35 ℃ will be brittle, heat resistance as PE.

(4) chemical stability: PP non-woven fabrics with good chemical stability, in addition to acid erosion, the other chemical reagents are relatively stable, Sanitray Nonwoven Fabric but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons can make PP non-woven Cloth softening and swelling, chemical stability with the increase in crystallinity also increased. Therefore, PP non-woven fabrics suitable for the production of Russian chemical pipeline and accessories, Sanitray Nonwoven Fabric anti-corrosion effect is good.

(5) Electrical properties: non-woven fabric of high-frequency insulation performance is excellent, because it is almost no water, so the insulation performance is not affected by humidity, a higher dielectric coefficient, and with the temperature rise, Sanitray Nonwoven Fabric can be used to make heat Of the electrical insulation products, the breakdown voltage is also high, suitable for electrical accessories. Anti-voltage, Sanitray Nonwoven Fabric good arc resistance, but high static electricity, easy to contact with the copper aging.

(6) weatherability: non-woven fabrics are very sensitive to ultraviolet light, adding zinc oxide thiopropionate cinnamon, carbon black type of similar milky white filler can improve its aging resistance.

The practical function of disposable hygiene is to capture, transport and store liquids or solids while being comfortable and healthy (see Figure 1). Sanitray Nonwoven Fabric These products are also common in the production process: high-speed rotating shaft on the base network (non-woven film, multi-channel diaphragm) and elastic materials (stranded and stretchable film).

Although the basic function of disposable hygiene products has always been the same, randomness and comfort are becoming more and more important. The current trend of disposable hygiene products is to be more like "clothing", or when wearing "less obvious." This trend is particularly important for adult incontinence products, Sanitray Nonwoven Fabric because an active elders do not want to be known to be wearing "diapers" - the traditional disposable diapers or loose plastic or "sand" sounds that are wearing diapers The This "like clothing" trend can be transformed into the specific features being designed and implemented:

• thinner and softer

• Better comfort

• Functional enhancement (eg odor control, humidity indication, skin care that promotes skin health, etc.)

Product design, material use and production processes are factors that help improve cost-effectiveness, and they meet these changing needs. More lightweight substrates, Sanitray Nonwoven Fabric advanced materials and appearance, stretch film and elastic material used to increase the addition of special additives or adhesive formulations are on this high performance, like clothing, Sanitray Nonwoven Fabric like a one-time health supplies support. However, they themselves may also be problematic - that is, processing and processing as well as interactions and effects with other material components.
