Abstract
The present invention relates to a biodegradable landscape fabric comprising spunlaced cellulosic fibers which comprise 0% to 75% wood pulp fibers and 25% to 100% regenerated cellulosic fibers without fiber binding materials and may further comprise a colorant.
Claims5
A biodegradable landscape fabric, comprising
- spunlaced cellulosic fibers which comprise 25% to 75% wood pulp fibers and 25% to 75% regenerated cellulosic fibers and without fiber binding materials,
- the biodegradable landscape fabric being about 55% softwood pulp fibers and about 45% spunlaced regenerated cellulosic fiber,
- the softwood pulp fibers combined on top of the spunlaced regenerated cellulosic fiber forming a dried combined sheet;
- the combined sheet spunlaced together into a single consolidated sheet;
- the single consolidated sheet of biodegradable landscape fabric being substantially cellulosic.
2 more elements
A biodegradable landscape fabric, comprising
- at least a portion of the biodegradable landscape fabric including at least about 25% to 75% wood pulp fibers and including at least about 25% to 75% regenerated cellulosic fibers and without fiber binding materials,
- wherein the biodegradable landscape fabric includes about 55% softwood pulp fibers at about 44.4 g/m2 and about 45% lyocell spunlaced regenerated cellulosic fiber at about 32 g/m2;
- the softwood pulp fibers combined on top of the lyocell fiber to form a combined sheet;
- the combined sheet spunlaced together into a single combined sheet;
- wherein the biodegradable landscape fabric has a basis weight of about 71 g/m2.
