With good elastic recovery rate；

With good heatproof dimensional stability, the flocculus handles the shrinking percentage after 5min at 200 DEG C and is less than or equal to 2%, and conventional meiting powder understands rapid desufflation at 200 DEG C and melts felting together；

With excellent fire resistance and wash durability.

With good thermal property, its full and warm rate of the flocculus of 100g is 70.3%, thermal resistance value 0.2337m2K/W.

Test method

Bulkiness：

Tested according to standard GB/T/T24281.2-2009, each sample for needing to test is cut into 10 pieces 220mm × 220mm, when flocculus thickness is less than 20mm, according to 5.2 instrument tests in standard, when flocculus thickness is more than or equal to During 20mm, tested according to 5.3 Instrumentals in standard, reading is accurate to 0.1mm, the average value of 10 tests is the thickness of flocculus Degree.It is 0.1Kpa to apply pressure.

Elastic recovery rate：

According to GB/T24281.2-2009, flocculus is cut into, the square of 220mm*220mm, first according to GB/ T24281.2 methods, the original depth d1 of flocculus is tested under 0.1Kpa pressure.Then flocculus no-station pole canopy is laid in level table On, the level board of the 220*220 made of glass is placed in top, then the metal squares of 0.5KG are placed on to the center of level board Position, maintains 5 minutes, and after metal derby is removed, flocculus is placed after ten minutes, then is testing its thickness under 0.1Kpa pressure D2, then calculates the elastic recovery rate of flocculus.

Flocculus elastic recovery rate calculation formula is as follows：

Flocculus elastic recovery rate=d2/d1 × 100% (numerical value is bigger, represents that elastic recovery is better)

Heatproof dimensional stability：

High temperature dimensional stability：Standard atmosphere condition carries out damping to sample as defined in GB/T 6529, and sample is cut Into 10cm × 10cm, mark is horizontal and vertical, measurement physical length lateral length M1, longitudinal length M2.200 DEG C of baking ovens are put into connect After continuous drying 10min, take out, measure sample vertically and horizontally length again, lateral length N1, longitudinal length N2, calculates horizontal stroke respectively To shrinking percentage S1, longitudinal contraction rate S2：

Lateral shrinkage S1=(M1-N1)/M1 × 100%

Longitudinal contraction rate S2=(M2-N2)/M2 × 100%

Fire resistance：

Combustibility test method：GB/T 5455-1997, point under defined burner is placed on by the sample of 30cm*8cm Combustion, after measuring gage determines burning time 12s, after flame time t, smoldering time T and the char length L of sample.

Anti-flaming washable performance：

Combustibility growth rate after washing：By flocculus according to national standard《GB/T8629 Textile Tests home washings and Drying program》Method is washed, its after flame time of re-test t1, smoldering time T1, char length L1 after washing 10 times.Then Calculate its growth rate：

After flame time growth rate=(t1-t)/t × 100%；

Smoldering time growth rate=(T1-T)/T × 100%；

Char length growth rate=(L1-L)/L × 100%；

Thermal property：

The thermal property of flocculus is weighed using calorific value, the thermal resistance value of flocculus is higher, illustrates that its warming effect is better.

The test method of thermal resistance value：According to GB/T11048-2008, sample is cut into the square of 500mm × 500mm, Tested using static flat band method specified in standard, measure the thermal resistance value Rct (units of sample：m2.W/K).

Warming wash durability：

Washing rear conservation rate and weigh the performance that flocculus water resistant is washed using thermal resistance, it is better to wash rear conservation rate, illustrates that flocculus resists The ability of washing is strong.

Thermal resistance washes rear conservation rate：By flocculus according to national standard《GB/T8629 Textile Tests home washings and drying program》 Method is washed, and according still further to above-mentioned GB/T11048-2008 after washing 10 times, tests the thermal resistance value Rct1 after its washing, then Calculate it and wash rear conservation rate：

Wash rear conservation rate=Rct1/Rct × 100%；
