An isolated nucleic acid molecule is provided comprising a nucleotide sequence which encodes a glutamine:fructose-6-phosphate amidotransferase from E. coli which is particularly suitable for expression in cotton plant cells. The invention also relates to plant cells or plants, in particular to cotton plant cells or cotton plants which produce an increased amount of positively charged polysaccharides in their cell walls. Furthermore, methods and means are provided to increase the content of positively charged polysaccharides in the cell walls of cotton cells, in particular in cotton fibers. Fibers obtained from such cotton plants have an altered chemical reactivity which can be used to attach reactive dyes or other textile finish reagents to these fibers.

The invention provides for a method of manufacturing artificial turf (1000). The method includes creating a polymer mixture, such as polymer mixture (400), where the polymer mixture is at least a three-phase system. The polymer mixture includes a first polymer, a second polymer and a compatibilizer. The first polymer is a polyamide (PA) and the second polymer is a polyethylene (PE). The first polymer is included in an amount of 0.125 percent to 5 percent by weight, the second polymer is included in an amount of 60 percent to 97 percent by weight and the compatibilizer is included in an amount of 0.375 percent to 15 percent by weight. The first polymer and the second polymer are immiscible, and the first polymer forms polymer beads surrounded by the compatibilizer within the second polymer.
