The flexible strength in cold days！

The morning mist at the end of November had not yet dissipated when the machines in the textile workshop began to murmur softly. Rolls of pure white yarn glide lightly on the rollers. This is PP yarn, combining the toughness of plastic with the softness of fibers, weaving a warm backdrop for life and production in the gradually colder season.

This yarn made from polypropylene has an unknown toughness. It is not afraid of moisture. Even in the damp and cold air at the end of November in the south, it can remain dry and fluffy. It is not easy to break when stretched and can still return to its original shape after repeated rubbing. At this moment, a batch of PP yarn is being woven into flood control geotextile and is about to be sent to the places in need to resist the possible ice flood in winter.

In the garment workshop, designers are making outdoor coats with fabric blended with PP yarn. After adding PP yarn, the fabric weight was significantly reduced, but it gained the characteristics of wind and water resistance. Worn on the body, it can not only block the cold wind from the street but also does not give a heavy sense of restraint, making it very suitable for short trips at this time of year. The scraps will not be wasted either. After being crushed, they can be remelted and spun into filaments, forming a closed-loop utilization.

In the corner of the warehouse, the packing straps used for bundling goods have a faint luster, which is also the "transformation" of PP yarn. It has strong anti-aging ability. Even if it is stored outdoors and exposed to the frost and snow of winter, it is not easy to crack. Workers can firmly bind boxes of supplies without much effort. Among these supplies, there might be winter rations wrapped in PP yarn woven bags.

Technicians are adjusting the spinning temperature. Minor parameter changes can make the feel of PP yarn closer to that of natural fibers. Nowadays, through modification technology, PP yarn can also have the function of moisture absorption and sweat wicking. The sports socks made from it can still keep the feet dry after winter exercise, breaking people's fixed impression that synthetic fibers are stuffy and hot.

As dusk seeped into the workshop, the PP yarn had transformed into rolls of fabric and bundles of packing straps. This seemingly ordinary yarn, with its diverse properties, silently supports the operation of life in the chill of late November, warming every ordinary day with its flexible strength.
