Microplastics have been an increasing environmental concern in recent years. Most people believe that microplastics exist in plastic products. But actually, microplastics can be released during conventional washing<\/b><\/u><\/strong><\/a>. Large amounts of synthetic microfibers can be shed from textiles. They are discharged into natural waterways with laundry wastewater. This becomes an important source of marine microplastic pollution. Currently, eco-friendly fabrics have not been widely used. According to relevant studies, cold-water washing is a low-cost, high-efficiency, and easy-to-implement method to reduce pollution.<\/p>\n

Hidden <\/b><\/strong>Environmental Risks<\/b><\/strong><\/h2>\n

Synthetic microfibers are tiny plastic fibers less than 5 millimeters. They are widely found in common garment fabrics (such as polyester, nylon, acrylic, and fleece fabric). They are also key materials in blended fabric garments. These fabrics are highly cost-effective, wear-resistant, and durable. They are widely used. However, the surface fibers are more likely to shed during repeated washing.<\/p>\n

A 2018 study from the Newcastle Innovation Center in the UK revealed the impact of this laundry pollution.\u00a0The research carried out tests on laundry applications for soiled garments. The results showed that thousands of synthetic microfibers could shed during a single laundry cycle. Due to their small sizes, urban wastewater treatment systems fail to completely remove them. Most microfibers can finally reach rivers, lakes, and oceans.<\/p>\n

According to global environmental research, microplastic fibers released during laundry processes account for 35% of marine microplastic pollution. These microplastics are difficult to biodegrade. They can persist in the water environment for a long time. They can also absorb toxic and harmful substances from water. They are often mistakenly eaten by marine organisms (such as plankton, fish, and shrimp). Finally, they accumulate along the food chain and return to the human body. This can pose broader ecological risks.<\/p>\n

Key Washing Conditions<\/b><\/strong><\/h2>\n

Many people assume that fiber shedding is caused by poor fabric quality. But cleaning conditions are the key factor. The amount of fiber shedding can be affected by multiple factors (agitation intensity, wash duration, detergent type, and water temperature). Among them, water temperature has the greatest effect.<\/p>\n

Hot water can change the internal structure of synthetic plastic polymers. Fibers can swell and become brittle when heated. The stability of internal molecular structures can be significantly reduced. Originally tight fiber surfaces are more likely to crack and shed. This can cause increased microplastic shedding. A research team at a marine plastics laboratory in Vancouver, Canada, once conducted several washing tests on 37 common synthetic fabrics. The experimental data were surprising. Some fleece fabric garments could shed up to 250,000 microfibers in one wash cycle.<\/p>\n

At the same time, the research showed that during the first few wash cycles, new garments could shed more fibers than old garments. After manufacturing and processing, a large number of loose fibers remain on the fabric surface. They shed when garments are agitated and exposed to heat during washing. Daily high-frequency washing makes laundry a critical source of global microplastic pollution.<\/p>\n

Advantages of Cold-Water Washing<\/b><\/strong><\/h2>\n

Based on multiple studies, if the wash temperature is kept between 15\u2103\u00a0and 20\u2103, fiber shedding can be effectively limited at the source. Compared with washing at temperatures above 40\u2103, cold-water cleaning can reduce the amount of microplastic release by around 30%. A comparative study by the Newcastle research team found that during a 15\u2103\u00a0cold-water cleaning for 30 minutes, the amount of fiber release is less than that of 40\u2103\u00a0high-temperature long-duration washing. This significantly improves the results of temperature control to reduce pollution.<\/p>\n
