Abstract:
The present invention is a non-woven web or composite structure comprising (a) from about 50 to about 90 weight percent of a natural cellulose fiber; (b) from about 10 to about 50 weight percent of a binder fiber component; (c) from 0 to about 20 weight percent of a filler; and (d) from 0 to about 8 weight percent of a dye or pigment.
Abstract:
This invention relates to compositions, paper, thermoplastic sheets, and medical paper containing cellulose ester, alkylpolyglycoside (APG) or a mixture of APG and polyether glycol, and, optionally, cellulose. The process of incorporating APG or a mixture of APG and polyether glycol in paper composed of cellulose ester fibers and cellulose fibers and to calendaring of such paper is also disclosed.
Abstract:
A thermoplastic film is comprised of an admixture of 20 to 85 weight percent cellulose ester fibers and 80 to 15 weight percent cellulose fibers and a functional amount of a cellulose ester plasticizer. The film has an opacity in the range of 10 to 85 percent, a thickness in the range of 0.05 to 0.25 mm (0.002 to 0.010 inch), a porosity in the range of 0.0 to 50 ml/min/cm at a 1.0 centibar pressure drop and a compostability of less than 65 days fragmentation. The film is prepared by making a paper comprised of 20 to 85 weight percent cellulose ester fibers and 80 to 15 weight percent cellulose fibers and saturating the paper with a functional amount of a cellulose ester plasticizer. The saturated paper is subjected to heat and pressure for a period of time to obtain the thermoplastic film. The thermoplastic film is prepared without the use of solvents and is economically attractive since it is compatible with conventional paper printing materials and techniques.
Abstract translation:热塑性膜由20至85重量%的纤维素酯纤维和80至15重量%的纤维素纤维和官能量的纤维素酯增塑剂的混合物组成。 该膜的不透明度为10〜85%,厚度为0.05〜0.25mm(0.002〜0.010英寸),孔隙率为0.0〜50ml / min / cm 2的范围 1.0厘米巴的压降和堆肥不足65天的破碎。 通过制造由20至85重量%的纤维素酯纤维和80至15重量%的纤维素纤维组成的纸并且用功能量的纤维素酯增塑剂使纸饱和来制备膜。 饱和纸经受一定时间的加热和压力以获得热塑性膜。 热塑性薄膜是在不使用溶剂的情况下制备的,因而具有经济吸引力,因为它与传统的纸张印刷材料和技术相容。
