    • A method of producing a low-dust, fire retardant cellulose fiber material useful in producing insulation and other such products is provided. A liquid, comprising a solvent and at least one fire-retarding material soluble in that solvent, is applied to a cellulose source material, and the liquid is allowed to permeate into the cellulose source material. The liquid permeated material is dried to remove the solvent while the fire-retardant material remains in the cellulose source material. The dried fire-retardant cellulose source material is reduced in size and then de-dusted to produce a low to no dust, fire-retardant cellulose fiber material that has functionally equivalent fire-retardant properties as the dried fire-retardant cellulose source material before de-dusting.
    • 提供了一种生产用于制造绝缘材料的其它低尘,阻燃纤维素纤维材料的方法。 将包含溶剂和至少一种可溶于该溶剂的阻燃材料的液体施加到纤维素源材料上,并使液体渗透到纤维素源材料中。 将透液材料干燥以除去溶剂,同时将阻燃材料留在纤维素源材料中。 干燥的阻燃纤维素源材料的尺寸减小,然后除尘,以产生低至无粉尘的阻燃纤维素纤维材料,其具有与de之前的干燥阻燃纤维素源材料具有功能等同的阻燃性能 -dusting。
