Popular: non-woven spunbond nonwovens
The shape of the shopping bag is made from spun-bonded non-woven fabric, serving as an environmental protector against white pollution. The spunbond industry in China has experienced rapid growth within the non-woven fabric sector, yet it still lags behind international standards. Despite the promising market potential for spun-bonded nonwovens, the entire industry requires further optimization and adjustment.
With the implementation of the "plastic limit order," new products such as vegetable field and super wetness bags gained popularity in urban areas due to their convenience after returning home. Traditional spun-bonded nonwoven fabrics gradually lost ground as thin plastic bags became less common. This shift forced people to reconsider the equipment used for shopping, indicating that while the market remains large, adjustments are still necessary.
Soon after, many consumers turned to non-woven adhesive methods to produce polypropylene, polyester, and nylon-based shopping bags. White pollution is caused by a variety of plastic products, with different weight requirements and growing public awareness of environmental issues. These materials are versatile, easy to process, and widely used in coating, compounding, and other applications. As a result, their role as environmental guardians in combating white pollution is highly promising.
Polyester spun-bonded non-woven products are primarily used in geotextiles, waterproofing materials, composite reinforcements, automotive components, cushioning materials, and shoe chemical sheets. In the manufacturing process, spun-bonded nonwovens have found widespread application across various industries, thanks to their performance, production techniques, and material versatility.
When shopping, spun-bond non-woven pockets have largely replaced plastic bags, offering advantages in efficiency and durability. Over the past 30 years, they have become a fast-growing segment of the market, despite some challenges. Today, they represent the technological core of the spun-bond process, expanding into textiles, paper, and film industries.
In non-woven fabric production, approximately 40% to 50% of the previous drafts were mechanically drafted. However, due to the high volume of spun-bonded non-wovens, small-scale production often uses either the spunbond or meltblown method, which can lead to uneven fiber distribution. With polypropylene as the main raw material, the industry faces challenges in equipment quality, management, and technical development. In technologically advanced countries, more efficient spinning methods are being adopted to reduce costs and improve product quality.
The air flow drafting method has significantly enhanced the appeal of spun-bonded non-wovens, particularly in countries where this technique is widely used. Recently, many enterprises have focused on producing plastic bags using this method. At the end of the 20th century, unlike traditional nonwovens, there were three types of non-industrial developments in the formation of spunbond production lines.
As the spunbond nonwovens industry continues to grow, it has entered the North American market, which currently has the lowest level of industrial development. Both pipe-type and wide-slit drafting methods offer excellent mechanical properties, leading to increased competition in the market.
Non-woven fabrics now account for more than half of the total non-woven market. Techniques such as stretch, narrow slotted drafting, and others have improved characteristics like elongation, tearing strength, and overall performance compared to dry methods. This shows that the conventional spunbond method, which involves direct polymer forming, is still a key production approach alongside wet and meltblown methods.
Despite these advancements, meltblown nonwovens, especially sticky products, continue to hold a significant market share. To meet diverse consumer needs, textile technologies involving polypropylene, polyester, and polyamide have evolved, focusing on high-level production, market expansion, and product development.
Through processes like laying into a net, web bonding, and molecular structure control, the industry has expanded its applications in thermal bonding, chemical bonding, and mechanical reinforcement. While spunbond nonwovens may not be as crystalline as other materials, they remain a vital part of the textile industry.
Spunbond technology continues to evolve, aiming to improve fiber properties, enhance physical and mechanical performance, and develop functional nonwovens with features such as soundproofing, tamper-proofing, and non-toxicity. Despite limitations in production efficiency and cost, the future of spunbond nonwovens looks bright, with a focus on high elongation, stability, permeability, and corrosion resistance.
In summary, the spunbond nonwoven industry is continuously improving, adapting to market demands, and exploring new applications in medical, industrial, and consumer sectors. Its potential for innovation and sustainability makes it a crucial player in the global non-woven fabric landscape.
