Various common properties of PP non-woven fabrics!(1) Physical propertiesPP non-woven fabric is non-toxic, tasteless milky white high crystalline polymer, is currently one of the most light varieties of plastic, especially stable to water, in the water absorption rate of 14h is only 0.01%. Molecular weight of about 8-150,000, good formability. However, due to the large shrinkage rate, the original wall products are easy to sag, and the surface color of the products is good and easy to color.(2) Mechanical propertiesPP 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 strong resistance to bending fatigue, and the dry friction coefficient is similar to nylon, but it is not as good as nylon under oil lubrication.(3) Thermal performancePP non-woven fabric has good heat resistance, melting point at 164-170 ° C, products can be sterilized at temperatures above 100 ° C. Under the action of no external force, 150℃ does not deform. The embrittlement temperature is -35℃, and embrittlement will occur below -35℃, and the heat resistance is not as good as PE.(4) Chemical stabilityPP non-woven fabric has good chemical stability, in addition to being corroded by acid, other chemical reagents are relatively stable, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc., can make PP non-woven fabric soften and swell, chemical stability with the increase of cleanliness and improve.(5) Electrical propertiesNon-woven high frequency insulation performance is excellent, because it is almost no water absorption, so the insulation performance is not affected by humidity, has a high dielectric coefficient, and with the rise of temperature, can be used to make heated electrical insulation products, breakdown voltage is also very high, suitable for electrical accessories and so on. Good voltage resistance and arc resistance, but high static electricity, easy aging in contact with copper.(6) Weather resistanceNon-woven fabric is very sensitive to ultraviolet rays, adding zinc oxide thiopropionate dilauryl grease, carbon black similar milky fillers can improve its aging resistance.Anhui Xiangshuo Nonwovens Technology Co., Ltd. is located in Wushan Town, Changfeng County, Hefei City, Anhui Province, near Jiangsu, Zhejiang and Shanghai, convenient transportation, covers an area of 42 acres, the company was established in July 2019, the registered capital of 10 million yuan.

With the invasion of the hot summer, the garment fabric industry ushered in a prosperous summer chapter. Many textile businesses have focused on the "cool" demand, and innovated the introduction of fabrics with multiple functions such as cool feeling, quick drying, mosquito prevention, and sun protection, which quickly occupied the hot seats in the summer market.Sunscreen clothing has become a new fashion favorite, and the functional textile fabrics behind it are in short supply, and the market heat continues to rise.Many textile operators located in China Textile City are actively transforming, committed to the research and development of functional fabrics, and strive to meet the dual pursuit of textile customers for the appearance level and practicality of fabrics.They said that the current market is not only favored by the high level of appearance of the fabric, but also values its practical functions such as breathability, mosquito repellent, quick drying, deodorization and efficient sun protection. This transformation boom not only led to the continued growth of orders, but also demonstrated the textile industry's keen insight into market trends.At the same time, there are new developments in the international market. According to the U.S. Department of Commerce, U.S. apparel imports remained stable in the first half of 2024, with significant increases in imports to Cambodia and India and reductions in imports to Vietnam and Bangladesh.Imports of cotton clothing recovered significantly, mainly due to lower unit prices, which reduced the cost of cotton. Imports of cotton garments from Sri Lanka increased by 22.4 percent, but increased by 3.8 percent.In terms of cotton apparel imports, the competition between China, Bangladesh, Vietnam and India is more balanced. The unit price of all producing areas fell, the unit price of Sri Lanka fell by 16%, and the unit price of cotton clothing in Bangladesh fell by more than 10%, effectively promoting exports.Similarly, a sharp drop in the unit price of chemical fiber clothing in China and Vietnam also boosted exports. In the first half of 2024, China's apparel exports to the United States benefited from a decline in unit prices, and U.S. apparel imports to China increased by 1.3% year-on-year, while apparel imports to other producing areas decreased by 0.3% year-on-year.Despite the competitive pressure from other countries, China's textile industry still occupies a place in the global market with its strong production capacity and innovation ability.Declaration: The content of this article is organized from the Internet, and the copyright belongs to the original author; If there is infringement, please inform in time and contact to delete.

What is the application prospect of spunbonded non-woven fabric?Spunbonded non-woven fabric is a continuous filament formed by polymer extrusion and stretching, and then laid into a net, and finally made of non-woven fabric by self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. It has many excellent characteristics, such as high temperature resistance (polypropylene can be used in the environment of 150℃ for a long time, polyester can be used in the environment of 260℃ for a long time), low temperature resistance, aging resistance, ultraviolet resistance, high elongation, stability and good permeability, corrosion resistance, sound insulation, mothproof, non-toxic and so on.The main materials of spunbonded non-woven fabrics are polyester and polypropylene, which are widely used in many fields. In terms of household goods, it is used to make clothing softeners and additives, vacuum cleaner bags, etc. In the field of packaging, it is used for cable wrapping cloth, handbag, container bag, wrapping flower materials, etc. In terms of decorative materials, it is used for wall decorative cloth, floor leather base, electrostatic flocking base cloth, etc. In addition, it is also widely used in agricultural harvest cloth, crop and plant protection, weed protection belt, as well as high-grade breathable (wet) waterproof material base cloth, filter materials, insulation materials, electrical appliances, reinforcement materials, support materials, automotive decoration materials and so on.The light weight, high strength, high permeability, softness and excellent physical and mechanical properties of spunbonded non-woven fabric make it an ideal choice in medical, health, industry, agriculture and other fields. With the progress of technology and the increase of market demand, the application prospect of spunbonded nonwovens will be broader.Anhui Xiangshuo Nonwovens Technology Co., Ltd. is located in Wushan Town, Changfeng County, Hefei City, Anhui Province, near Jiangsu, Zhejiang and Shanghai, convenient transportation, covers an area of 42 acres, the company was established in July 2019, the registered capital of 10 million yuan.
