Polyester spunbond nonwoven fabric has emerged in many fields with a series of outstanding characteristics. Its unique performance not only determines its wide application, but also makes it stand out in competition with other types of non-woven fabrics.
High strength and good wear resistance
High strength Polyester spunbond nonwoven fabric has excellent strength and can withstand high pressure and friction. From the data, its tensile strength is usually ≥ 35N/5cm in the longitudinal direction, ≥ 28N/5cm in the transverse direction, ≥ 10N in the longitudinal direction, and ≥ 8N in the transverse direction. This allows it to maintain structural integrity and is not easily damaged in environments with frequent friction or significant external forces. For example, in the field of industrial filtration, when dealing with fluids containing particulate impurities, polyester spunbond nonwoven fabric can effectively filter impurities with its own strength, while resisting particle erosion and wear, extending its service life. In the field of packaging, it can also provide reliable protection for packaging heavy or sharp edged items, preventing packaging damage caused by item movement or collision.
Excellent high temperature resistance
The melting point of polyester is around 260 ° C, which endows polyester spunbond nonwoven fabrics with excellent high temperature resistance. It can be used for a long time in an environment of 150 ℃ and can maintain stable external dimensions. In the heat transfer printing process, the pattern needs to be transferred onto the fabric through high temperature and high pressure. At this time, polyester spunbond non-woven fabric can adapt well to this high temperature environment, ensuring a smooth printing process and clear and firm patterns. In scenarios involving high-temperature liquid filtration such as transmission oil filtration, it can also stably perform its filtering function without deformation or damage due to temperature rise, ensuring the normal operation of the filtration system.
Aging resistance and UV resistance
The aging resistance and UV resistance of materials are crucial in outdoor environments or long-term use. Polyester spunbond nonwoven fabric performs well in this regard, effectively resisting the erosion of ultraviolet rays and aging factors in the natural environment. This is due to the stability of its molecular structure, which allows it to maintain its physical properties and appearance quality even after prolonged exposure to sunlight or harsh environments. Taking agricultural greenhouse covering materials as an example, the sunshade net made of polyester spunbond non-woven fabric can maintain good strength and sunshade effect even after prolonged exposure to sunlight and rain, providing a stable growth environment for crops. When used as a substrate for outdoor advertising printing, it can ensure that the image does not fade or break for a long time, maintaining the promotional effect of the advertisement.
High elongation and dimensional stability
Polyester spunbond nonwoven fabric has a high elongation, which can stretch to a certain extent without breaking, while also having good dimensional stability. When stretched by external force, it can deform according to demand, and after removing the external force, it can basically return to its original size. This characteristic makes it perform excellently in some application scenarios that require materials to have flexibility and shape memory function. For example, when making elastic packaging materials, it can tightly fit the shape of the product, providing a good wrapping effect, and during transportation and storage, it will not undergo excessive deformation or breakage due to slight shaking or squeezing of the product. In the application of the base fabric of building waterproofing membrane, it can deform with small displacements such as settlement and expansion of the building, always maintaining the integrity of the waterproofing membrane and effectively preventing leakage.
Stable chemical properties and environmental friendliness
Polyester spunbond non-woven fabric has the characteristics of corrosion resistance, moth resistance, and non toxicity. It can resist the erosion of various chemical substances, whether it is common chemical reagents such as acids and bases, or some special chemical media in industrial production, it is difficult to cause damage to it. This characteristic makes it widely used in packaging, filtration and other aspects of industries such as chemical and pharmaceutical. For example, in the packaging of chemical raw materials, it can ensure that the packaging materials are not corroded by chemicals, thereby ensuring the quality and storage safety of the raw materials. Its anti moth performance makes it highly favored in textile, home and other fields, such as for making mattress liners, clothing storage bags, etc., which can effectively prevent insect damage. Moreover, the entire production process is additive free, making it an environmentally friendly product that meets the current demand trend for green materials.
Good breathability and water repellency
From the perspective of air permeability indicators, its air permeability is usually between 100-500L/m ² · s (pressure difference of 125Pa), which can ensure smooth air circulation. In the field of healthcare, good breathability can keep medical staff and users comfortable when used to make surgical gowns, masks, and other products, avoiding discomfort caused by stuffiness. At the same time, it is also a water repellent non-woven fabric, and water droplets will directly slide off its surface. The larger and thicker the weight, the better the water repellent performance. This feature makes it play an important role in some situations that require both waterproofing and breathability, such as outdoor protective clothing, building waterproof breathable membranes, etc. It can not only block the intrusion of rainwater, but also allow the internal moisture to be discharged, keeping it dry.
Special gamma ray resistance performance
In the field of medical products, polyester spunbond nonwoven fabric has a special advantage, which is its resistance to gamma rays. This means that it can be directly disinfected with gamma rays without compromising its physical properties and dimensional stability. Compared to other non-woven materials, this characteristic makes polyester spunbond non-woven fabric more competitive in the production of medical supplies. For example, in disposable medical surgical kits, medical equipment packaging, etc., gamma ray disinfection is a commonly used and efficient disinfection method. Polyester spunbond non-woven fabric can adapt well to this disinfection process, providing a guarantee for the safe use of medical products.
In summary, polyester spunbond nonwoven fabric has become an indispensable and important material in many industries due to its unique properties in various aspects. With the continuous advancement of technology, its performance is expected to be further optimized and expand its wider application space.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
