The impact of flame retardant STC on polyester fabric technology

The influence of flame retardant STC mass fraction on fabric properties. The mass fraction of Silky Slippery C-1 is 10%. Others adopt the process in Section 1.2 to examine the influence of flame retardant STC mass fraction on fabric properties. See 1. In 1, with the retardant As the mass fraction of flame agent STC increases, the flame retardant effect of polyester fabrics is significantly enhanced; when the mass fraction of STC reaches 30%, the flame retardant effect can reach the national standard B2 standard; when the mass fraction of STC reaches 40%, the flame retardant effect can reach the national standard. B1 level standard; however, when the mass fraction exceeds 40%, the flame retardant effect changes little and the low temperature resistance is poor. In summary, the appropriate mass fraction of flame retardant STC is 40%.

2.2 The influence of the mass fraction of silky smooth C-1. The mass fraction of flame retardant STC is 40%. Other process conditions are the same as in Section 1.2. To examine the influence of the mass fraction of silky smooth C-1 on fabric properties, see 2.1 Flame retardant STC.

Therefore, the mass fraction of soft and smooth C-1 is 15%. 2.3 Effect of the amount of glue applied on the coating: The mass fraction of Silky C-1 is 15%, and the mass fraction of the flame retardant STC is 40%. Other process conditions are the same as in Section 1.2. For the effect of the amount of glue applied on fabric properties, see 3 Coating Glue Table 3 Influence of glue dosage on the performance of polyester fabric Item Hydrostatic pressure/Pa Moisture permeability/[g·(㎡·d)-1] Flame retardancy Breaking strength Tear strength Low temperature resistance (-40℃) Warp and weft continued Burning time/s smoldering time/s damage length/cm afterburning time/s smoldering time/s damage length/cm warp direction/N weft direction/N warp direction/N weft direction/N warp direction and weft direction glue amount/ (g·m-2) 10372641803.50.712.010.310.66205065041 No cracking points No cracking points 12421741000010.2009.66275094839 No cracking points No cracking points 1545114010008008.36295124435 There are cracking points No cracking points 1 851973900008.1008.26285134031 There are cracks. There are 3 cracks. With the gluing As the amount of glue increases, the flame retardant properties of polyester fabrics improve; when the amount of glue reaches 12g/m2, the flame retardant effect of the fabric is good; when the amount of glue exceeds 15g/m2, the flame retardant effect increases very little, and the low temperature resistance and tear resistance The breaking strength decreased to a great extent. Therefore, the glue amount of the coating is selected to be 12g/m2.

At present, this product has completed laboratory small tests, pilot tests and large-scale production tests, and has been put into production for 20,000 meters. The product performance is stable. 3 Conclusion (1) The polyester fabric is coated with flame retardant STC40%, soft and smooth C-115%, and the glue amount is 12g/m2. The flame retardancy and other performance indicators can meet the requirements of the army’s individual sleeping bags. (2) According to different polyester fabrics and performance index requirements, different formulas and process conditions can be selected for processing x19stQXH
