Polypropylene fabric for thermal underwear
One of the inherent characteristics of polypropylene yarn for thermal underwear is that it retains warmth in all fibers. When the thermal conductivity of air is 1, the thermal conductivity values ​​of various types of fibers are as follows:
  Polypropylene, vinylon, silk, polyester, wool, acrylic, nylon, viscose
  In fabrics, the lower the thermal conductivity of the fiber, the less heat the fiber itself loses. Therefore, low thermal conductivity improves its warmth function. As can be seen from the above, the polypropylene fiber of the thermal underwear has a lower thermal conductivity, so that its thermal insulation is superior to other fibers.
The polypropylene fabric yarn produced by our company has the following advantages:
1. Lighter fiber: less density, 40% lighter than cotton, 30% lighter than polyester, lightly lubricated;
2. Fibers that are warmer than wool: the thermal conductivity is lower in existing natural fibers and synthetic fibers, and the heat loss rate is lower.
3, good color fastness: the original liquid dyeing, color fastness is unmatched by other fibers after dyeing and finishing;
