X-Crepe A Paper for Countless Industrial Uses
Can be formed into simple compound curves, indented or deep grain embossed, saturated, coated, flocked, die cut, slit, sewn, taped, glued or cemented, laminated to itself or other materials.
How X-Crepe is made
Most creping processes consist basically of bonding paper to a smooth surface and "doctoring" or scraping it off with a smooth knife. The physical action of the knife working against the adhesive bond beneath paper and surface causes the formation of small pleats or folds in the paper. In general, the stronger the bond between paper and surface, the finer will be the pleats or folds.
Cross-creped kraft, or X-Crepe, is produced by a patented process in which kraft paper is bonded to a large cylinder at on angle of 45 degrees to the direction of rotation. The knife peels the paper from the cylinder, forming very fine pleats in one diagonal and imparting stretch in that diagonal direction as well as in both the machine and cross-machine directions.
The material is then adhered to a second cylinder which is equipped with a knife mounted at a 45 degree angle opposite to that of the first knife. Rotation of the cylinder results in similar pleats being formed on the opposite diagonal, and imparts stretch on the second diagonal as well as additional stretch in the machine and cross-machine directions.
Desiccant Bags
These heat sealed moisture and vapor absorbent bags contain silica gel and clay desiccant to prevent corrosion damage of packaged metals, moisture evaporation of pharmaceuticals and more. In this application, X-Crepe contributes:
Breathing Properties
X-Crepe allows moisture to pass through and is absorbed by the desiccant. Moulding Properties X-Crepe´s flexibility allows bags to be "jammed" into tight and irregular spaced spots.
Puncture Resistance
X-Crepe bags withstand heavy vibrations and rough handling. Coating Properties X-Crepe bags accept heat seal coatings from water based dispersions.
Printing Properties
X-Crepe bags can be printed by Flexo or Gravure methods.
Folding Doors
Special fire retardant X-Crepe forms the interior hinging of many vinyl coated accordion folding doors. In this application, X-Crepe contributes:
Sound Absorption:
X-Crepe has a high degree of sound absorption yet produces little or no noise when flexed.
Flexibility
X-Crepe contributes almost unlimited flex in the hinge area without cracking.
Saturation
X-Crepe is readily impregnated with fire retardant chemicals.
Versatility
X-Crepe accepts wafer borne glues for adhesion to interior paperboard slots and can be heat-sealed to steel slots with polyfilms.
Spiral Tubes
X-Crepe is preferred in covering cable leads for oil-filled transformers because it offers the following properties:
Saturation
X-Crepe is compatible with the special oils used to fill these transformers.
Adhesion
X-Crepe readily accepts the edge glues used in the manufacture of spiral tubes.
Temperature
X-Crepe withstands the wide temperature range generated in oil filled transformers.
Flexibility
X-Crepe moves without rupturing during the cable lead´s expansion and contraction.
Roll Edging
The introduction of X-Crepe, with it´s cloth-like qualities into the furniture trade, replaces costly and dated burlap roll edging. X-Crepe properties applied to roll edging and related usages are:
Flexibility
X-Crepe can be bent without rupturing into sharp neat corners used on square chairs. It can also be crimped smoothly for curved chairs.
Quick-Stitch
X-Crepe allows fast and easy stitching with the use of high-speed machines. Production is up: time and money are saved.
Durability
X-Crepe´s "toughness" allows installers to use hogrings. This reduces labor costs by eliminating a substantial amount of hand sewing.
Grinding Wheels & Surf Boards
The production of depressed center grinding wheels comes with a problem: excess mould wear in the areas of deepest
draw caused by the abrasive grits used to make the wheels.
Die-cut pieces of X-Crepe inserted in this area shields the mould from the grits, greatly reducing wear and tear. X-Crepe properties applicable to this usage are:
Mould Release
X-Crepe absorbs the phenolic resin allowing easier removal from the mould. It also acts as an adhesive to stick to the wheel.
Identification
X-Crepe´s various colors are used as identification codes on different wheels.
Flexibility
X-Crepe easily conforms to the compound curves in the mould without wrinkling or pleating.
Compression
X-Crepe provides a protective cushion to the mould by absorbing the sharp edges of the grit without rupturing.
Buffs
X-Crepe is used more and more in place of cloth buffs used in the finishing of stainless steel knives, forks and spoons. X-Crepe properties applicable to this usage are:
Flexibility
X-Crepe can be moulded and crimped to fit into the center steel ring holder.
Saturation
X-Crepe readily accepts buffing compound.
Tear Resistant
X-Crepe´s durability ensures a long lasting buff.
Creped on Bias
X-Crepe has a natural bias, cloth must be cut and resewn.
