The present invention is directed to a process for producing a modified olefin polymer in an extruder having a feed zone, a melting zone, optionally a mixing zone and optionally a die zone, (A) introducing a stream of an olefin polymer into the feed zone of the extruder; (B) introducing a stream of a free radical generator directly into the feed zone or the melting zone or the mixing zone, if present, of the extruder; (C) introducing a stream of a functionally unsaturated compound directly into the feed zone or the melting zone or the mixing zone, if present, of the extruder; (D) extruding themixture in the extruder at a temperature which is greater than the decomposition temperature of the free radical generator and the melting temperature of the olefin polymer but less than the decomposition temperature of the olefin polymer thereby producing the modified olefin polymer in the extruder; and, optionally, (G) passing the melt of the modified olefin polymer through the die zone to a pelletizer.

The invention discloses a method for manufacturing a pineapple leaf fiber anti-acarid mat. The method comprises the steps of: firstly opening and mixing raw fiber materials; secondly spinning the raw fiber materials into single yarns and weaving the single yarns into raw fabric; and finally trimming the raw fabric. The method is characterized by adopting the raw fiber material consisting of 30 to 50 mass percent of pineapple leaf fiber and 5 to 70 mass percent of other textile fibers which can be one, two or three types of fibers of hemp fiber, flax fiber or cotton fiber. The pineapple leaf fiber anti-acarid mat has the functions of cooling, moisture absorbing, moisture releasing, ventilating, feeling soft and comfortable, eliminating urtication and the like, and also has the excellent effect of resisting and preventing acaid; and the anti-acarid rate can reach more than 80 percent. The trimming process adopted by the invention can remove both oil stain in spinning process and a little of colloid and filoplume contained in hemp fiber so as to lead the mat to be softer, even, washing-durable, shrink-resistant, storage-durable and use-durable.
