一种新型环保日光温室大棚的保温棉的制备方法，包括以下步骤：
(1)制备土工布层：将30％的中空纤维和70％普通纤维进行切片混合，然后进行预结晶、干燥，接着进行螺杆挤出、预过滤、熔融纺丝、气流牵引、摆丝成网，最后进行针刺加固，卷绕成布，然后将土工布与PE膜进行复合，覆膜温度为140-170℃，得到土工布层；
(2)制备针刺毡层：将50％中空纤维和50％普通纤维在混棉机中进行切片混合，然后进行预结晶、干燥，接着进行螺杆挤出、预过滤、熔融纺丝、摆丝成网，最后进行针刺加固，梳理成布；
(3)制备絮片层：将40％的15d三维中空纤维、50％的7d三维中空纤维和10％的异型二维中空纤维进行混合，得到混合物，将得到的混合物与低溶点纤维进行混合成型，然后进行梳理、烘干，得到成品，其中混合物与低溶点纤维的加入比例为1:4；
(4)根据需要将土工布层、针刺毡层、絮片层及珍珠棉层进行复合，得到成品。
