棉秆皮纤维素纤维的梳理与细化

为获得线密度较小的棉秆皮纤维，根据棉秆皮纤维素纤维的结构形态，采用单一罗拉梳理、单一盖板梳理、罗拉盖板组合梳理方法对棉秆皮纤维进行机械细化处理。结果表明：棉秆皮纤维梳理之前需要进行加水并闷放12 h；对于单一罗拉梳理方法，在加水量为纤维质量的25% 时，梳理后棉秆皮纤维平均长度39.7 mm、平均线密度2.42 tex；对于单一盖板梳理方法，在加水量为纤维质量的15% 时，梳理后棉秆皮纤维的平均长度37.7mm、平均线密度2.2 tex；对于加水量为纤维质量的25%的棉秆皮纤维素纤维，采用罗拉梳理2 次盖板梳理1 次组合梳理方法，梳理细化后纤维平均线密度为1.9 tex，平均长度为39.6 mm，平均落纤长度为15.9 mm以及平均落纤线密度为3 tex。

Investigation on carding thinning of cotton-stalk bark cellulose fibers

In order to obtain cotton stalk bark cellulose fiber with small linear density, according to the structure morphology of cotton stalk bark fiber, the mechanically thinning of cotton stalk bark cellulose fibers was carried out using single roller carding, single flat carding and combined roller carding-flat carding method. Experimental results show that cotton stalk bark fibers needs to be added with water and hermetically wet for 12 h before carding. For single roller carding method, the mean fiber length was 39 . 7 mm and the mean fiber linear density 2 . 42 tex after carding when the water amount is 25% based on the fiber weight. For single flat carding method, when the water amount is 15% based on the fiber weight the mean fiber length is 37. 7 mm and the mean fiber linear density is 2. 2 tex after carding. For the cotton stalk bark cellulose fibers with the water amount of 25% based on the fiber weight, when the combined carding method of two roller carding-one flat carding is used, the mean linear density and mean length of the carded fibers were 1. 9 tex and 39. 6 mm, respectively, and the mean fell fiber length is 15. 9 mm and the mean fell fiber linear density is 3 tex.
