How to Make Paper Mosaics Read all of the steps before starting. Project Preparation Cut white cardstock or white construction paper as mosaic bases.
Kraft process and Paper machine Wood pulp for sack paper is made from softwood by the kraft process. The long fibers provide the paper its strength and wet strength chemicals are added to even further improve the strength. Both Paper mosaic and brown grades are made.
Sack paper is then produced on a paper machine from the wood pulp. The paper is microcrepped to give porosity and elasticity.
Microcrepping is done by drying with loose draws allowing it to shrink. A paper sack can be made of several layers of sack paper depending on the toughness needed. Kraft paper is produced on paper machines with moderate machine speeds.
The raw material is normally softwood pulp from the kraft process. Maintaining a high effective sulfur ratio or sulfidity is important for the highest possible strength using the kraft process.
The kraft process can use a wider range of fiber sources than most other pulping processes. All types of wood, including very resinous types like southern pine and non-wood species like bamboo and kenaf can be used in the kraft process. Qualities[ edit ] Normal kraft paper is strong and relatively coarse.
It has high tensile strength. Sack kraft paper, or just sack paper, is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability. Absorbent kraft paper is made with controlled absorbency, i. It is made of clean low kappa hardwood kraft and has to have a good uniformity and formation.
This paper requires the best possible machine direction strength and cross machine elongation. This is done by high fiber orientation on the papermachine. Hunting cartridge paper is a kraft paper used in shotgun shells. This paper needs a high tensile strength in the machine direction, which is the axial direction of the cartridges.
In the cross direction, the cartridge is supported by the gun-pipe, but a sufficient elongation is needed.
These papers require a good strength, with highly oriented fibers. Twisting paper is mostly opaque and often supercalendered.Kraft paper or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process..
Sack kraft paper, or just sack paper, is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability.. Pulp produced by the kraft process is stronger than that made by other pulping processes.
Create a design for your mosaic on a piece of scratch paper. When creating a design, it is important to make it strong, clear and simple—flowers, birds, fish, and fruit work well. Make sure this fits by entering your model number.; This mosaic craft kit for thousands of years craftsmen have used mosaics for all manner of designs This superb kit introduces crystaline mosaics – transparent coloured tiles for a magnificent stained glass effect.
