    • A manufacturing method of an FR-PTT(PolyTrimethylene Terephthalate) for reducing the smoke when burning is provided to find the inorganic group additives to be applied to the FR-PTT. When spinning the PTT, a phosphorous flame-retardant and an inorganic smoke inhibition agent are added by the ratio of 10 to 30 wt%:70 to 90 wt%. Two among Al(OH)3, KI, Ferrocene, SiO2, NaSbO3 are selected and mixed by the weight ratio of 5:1 to 1:5. The phosphorous flame-retardant is a cyclic phosphonic acid ester group flame-retardant with a specific chemical formula 1 and the content thereof is 1 to 4 wt%. The content of the inorganic smoke inhibition agent is 2 to 16 wt%. The proper use rate of the phosphorous flame-retardant and the inorganic smoke inhibition agent is 1:2 to 5. The inorganic smoke inhibition agent inhibits the generation of aromatic gas species.
    • 提供了用于在燃烧时减少烟雾的FR-PTT(聚对苯二甲酸丙二醇酯)的制造方法,以找到要施加到FR-PTT上的无机基添加剂。 PTT纺丝时,加入磷阻燃剂和无机烟雾抑制剂的比例为10〜30重量%:70〜90重量%。 选择Al(OH)3,KI,二茂铁,SiO 2,NaSbO 3中的两种,以5:1至1:5的重量比混合。 磷阻燃剂是具有特定化学式1的阻燃剂,其含量为1〜4重量%的环状膦酸酯基。 无机防烟剂的含量为2〜16重量%。 磷阻燃剂和无机烟雾抑制剂的适当使用率为1:2至5.无机烟雾抑制剂抑制芳族气体物质的产生。
