Publication number: 20130112623
Abstract: The invention describes a composite microfiber, which is comprising a polysaccharide polymer selected from the group consisting of cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, methyl cellulose, ethyl cellulose, n-propyl cellulose, isopropyl cellulose, cellulose acetate and combinations of two or more of these substances, and combinations of two or more of these substances, thereby the polysaccharide polymer further comprising substituents comprising a given formula, wherein k is 1 or greater, and wherein each moiety R1 is independently selected from H and methyl, and wherein each moiety R2 is independently selected from —H, —OH, —NH2, —SH, —OR3, —NHR3 and —NR3R4, —SR3, and wherein each moiety R3 and R4 are chemical groups independently selected from C1-C4 alkyl, C1-C4 alkoxy, C1-C4 alkoxy halide and C1-C4 heteroalkyl substituents, and is preferably selected from —CH3, —CH2—CH3, —CH2—OH, —CH2—CH2—OH, —CH2—CH2—NH2, —CH—CH(OH)—CH2—OH, —CH—CH(OH)—CH3, glycidyl, anhydride, sulfonic acid and hydroxys
