China's industry standard regulation, the warming rate of thermal cloth must not be less than 30%.And the serial kapok high-efficiency thermal protection underwear of our company's exploitation has good warmth retention effect, warming rate mean value about 50%, is better than cashmere, eider down.Thermal-conduction resistance is higher more than 20% than cotton product, and thermal-convection resistance is 2-3 a times of cotton product, and warming rate is advanced in the world.Moisture vapor transmission, softness, comfort level are better than all-cotton fabric; Have soft-touch, warm (the similar cashmere of sense of touch difference of ultra-fine kapok and textile product and the difference of wool) moisture absorption, lead wet, elasticity, comfortable several big characteristics:
1. insulation rate is (according to standard GB 1048-89, utilize YG606 type plate type fabric heat-insulation instrument test) mainly reflect the heat-conductive characteristic of lining, compare with polyester-cotton blend product with cotton as can be seen, the insulation rate of kapok cold-proof underwear obviously improves, and this illustrates that its conduction heat is high.(see figure 1)
2. Air permenbility reflects the performance of keeping out the wind (the present domestic heat loss through convection performance or the performance of keeping out the wind that does not have instrument to examine lining specially of lining, weigh the performance of keeping out the wind of lining herein with Y561 type air permeability tester), Air permenbility is bigger, and the heat loss through convection amount is bigger, and the performance of keeping out the wind is poor more.Obviously, the heat loss through convection amount of kapok cold-proof underwear is starkly lower than cotton and polyester-cotton blend control sample, illustrates that the performance of keeping out the wind is fine.(see figure 2)
3. moisture vapor transmission is the direct tolerance of the wet comfortableness of fabric, and the moisture vapor transmission of kapok and all-cotton fabric is suitable as can be seen for data from table, can illustrate also that theoretically two class formations are identical, hygroscopicity is identical, and the moisture vapor transmission of lining or wet comfortableness are suitable.So kapok and all-cotton fabric have similarly wet comfortableness, will never feel vexed steaming when wearing.Some people likes the wet comfortableness with Air permenbility reflection fabric, and in fact Air permenbility can not be directly corresponding with wet comfortableness, and for example a lot of dacron Air permenbilities are high but wet comfortableness still is bad, and vexed steaming is felt in affiliation.The opposite excessive warming effect of Air permenbility then can reduce.
Be that (in the serial kapok high-efficiency thermal protection underwear wherein two kinds) main performance with identical in structure cotton and polyester-cotton blend product is compared below:
The test index contrast table
Lining and four seasons clothes made from bombax cotton in a word, its products characteristics is light, soft, comfortable, smooth, bright-coloured, antistatic, easy entanglement not, moisture absorption, not mouldly do not eat into, and acid and alkali-resistance under the normal temperature is real green natural environment-friendly products.
