The increase in demand for flushable wet wipes is mainly due to the convenience, hygiene, functionality, cost and consumer awareness of environmental protection, but where is the future development direction of wet wipes, the development direction in the next few years, and non-woven fabrics What kind of efforts should the fabric manufacturer make?
1. Change the non-woven fabric base fabric
It is imperative to change the non-woven fabric base fabric for wet wipes. Due to the special structure of the existing sewage treatment system, if the size of the wet wipes exceeds a certain specification, it will cause clogging. This phenomenon occurs in the United States, the Netherlands, Sweden and the United Kingdom. All happened, so relevant government departments promulgated some unrealistic regulations. On the other hand, the price of petroleum-based non-degradable fibers is increasing so rapidly that it approaches or exceeds the price of degradable fibers, such as viscose and cotton fibers. The problem that consumers are unwilling to pay because of the high price of degraded products no longer exists. Although the price of wood pulp on the market is close to the highest level in history, it is still 50% cheaper than petroleum-based. Although the prices of wood pulp, viscose and cotton fiber will increase over time, some experts predict that the price of petroleum-based fiber will increase. The speed of fiber will definitely exceed that of non-petroleum-based fibers. These factors will prompt non-woven fabric manufacturers to reconsider when selecting fibers.
2. Increase the amount of wood pulp and cotton fiber
Increase the use of wood pulp and cotton fiber in the wet wipe non-woven fabric. The use of wood pulp is beneficial to reduce costs. The air-laid method has the advantage of using a higher proportion of wood pulp. The amount of wood pulp fiber in the commercial dust-free paper is now Has reached 85-90%. The early spunlace and airlaid + spunlace process can only use 50% wood pulp. Now the spunlace cloth with 60-70% wood pulp content has also been commercialized. The wet process + spunlace process is used for private The wood pulp content in brand toilet wipes can reach 80%.
Using wood pulp in wet wipes is the most environmentally friendly method, while the use of air-laid and spunlace methods to make wet wipes with cotton fibers is still popular among consumers. In addition, manufacturers have also noticed that the price difference between cotton fiber and other fibers such as viscose fiber and polypropylene fiber is gradually shrinking. Regenerated cellulose fiber is more sustainable and cheaper than new cotton fiber. With the adoption of manufacturers, it is expected that the application of regenerated cellulose fibers in wet wipes will increase.
3. From small size to be flushable to real flushable
Wet wipes are being washed away directly by the sewage treatment system from a certain size, turning to the real sense of being able to be washed away. Among the various uses of wet wipes and wipes, after moderate marketing policies, the sales of adult toilet wipes have continued to increase, and they have now become high-value and growing products.
4. Spunlace jacquard instead of hot embossing
In the past, the surface pattern of thin non-woven fabrics was usually realized by hot embossing. Due to the spunlace jacquard, the production speed would be slowed down, the jacquard quality was not high, and investment in jacquard equipment was required. Due to the frequent price fluctuations of polypropylene fiber, most non-woven fabric manufacturers rarely use it
Since the spunlace jacquard does not use the thermal bonding between the fibers produced by hot embossing (the fiber is thermally melted to produce the bond between the fibers, which is difficult to separate in the sewage treatment system), so the washable wet wipes It is a very ideal choice. Now the spunlace non-woven fabric can use almost all natural fibers, making it possible to process degradable and flushable products.
As the world's environmental pollution is increasing and consumers' awareness of environmental protection continues to increase, when the economic crisis gradually disappears, consumers begin to make rational purchases. In developed countries such as the United States, Western Europe, Japan, and some areas in developing countries, consumers are also advocating the concept of sustainable development and supporting them from purchasing actions. Dispersible wipes and wipes are a sustainable product, and the leftover products after the sewage treatment system can be used as useful soil amendments, rather than just becoming landfills in the garbage dump.
