DRAPERIES

DRAPERY STYLES

PINCH PLEAT

Style

Also known as “French Pleat” or “3 Finger Pinch Pleat”, this style is the most traditional and

widely used across the industry. Pinch Pleated draperies create a full, classic appearance and are

best suited to providing full coverage light blackout.

Design

Drapery fullness is physically “pleated” into the drapery

by creating 3 layered folds that are then stitched

together. Each pleat is stitched with a straight needle

1/2” from bottom of buckram using monofilament

thread. Standard spacing is 5 pleats per 54” fabric width,

however can be adjusted to accommodate different

fullness levels. Standard fullness is 200% unless

otherwise specified.

DRAPERY STYLES

ACCORDIAFOLD

Accordiafold is a trademark name for the accordion style pleating of drapery. Unlike Ripplefold, the spacing of the fabric is a result of its pleats which are sharp and crisp compared to any other style of drapery. Used primarily in Healthcare applications, Accordiafold draperies stack tighter when open but tend to leak light at the edges so are not the best choice for blackout applications. Additionally, due to the way they hang below the track, a full top treatment is required if complete room darkening is desired.

DRAPERY FABRICATION

LINING

Light filtering or Blackout, drapery linings enhance the characteristics of the base drapery in many

different ways:

• Depth and beauty – lining adds weight and volume to the drapery, making it appear richer

and fuller.

• Sound reduction – multiple layers of fabric reduce sound transmission.
• Insulation – layering the drapery creates air pockets providing insulation from the sun in

the winter months, and reduces drafts in the winter.

• Privacy – true blackout linings are 100% completely opaque, eliminating any chance of

“silhouetting”.

• UV Protection – harmful UV rays attack carpet fibers, paint, bedding, and furniture,

breaking down their surface causing cracking, drying, and bleaching. Blackout lining helps

to protect all of these and more.

• Uniform exterior appearance – especially nice when different face fabrics are used

throughout a building.

Polyester

An inherently Flame Retardant light filtering lining consisting of a 70/30 poly-cotton blended

weave. Standard color selections are White or Ivory.

2-Pass Blackout

This is an inherently Flame Retardant blackout lining consisting of a 70/30 poly-cotton base

fabric with 2 layers of foam coating on one side. Standard color selections are White or Ecru

on the foam side and Gray on the poly/cotton side.

3-Pass Blackout

This is an inherently Flame Retardant blackout lining consisting of a 70/30 poly-cotton base

fabric with 3 layers of foam coating. Standard color selections are White or Ecru on the foam

side and White on the poly/cotton side.

Overlocking

This is a method by which the raw fabric edge is

removed and a clean loop stitch is sewn around the

new edge to create a clean, finished edge that will

resist fraying or tearing. An overlock stitch is also

use to join fabric panels together. This method

creates an unobtrusive seam that flows with the

drapery without adding bulk or inflexibility.

WARRANTY AND CARE

Dry Cleaning (continued)

The following procedures are recommended by the International Fabricare Institute

NOTE!! Check the manufacturer’s recommendations for proper care and

cleaning of all face fabrics.

1. Inspect draperies for labels that recommend special care. Classify them for cleaning

method.

2. Make sure the draperies have been measured before cleaning. Pass information to

finisher.

3. Run underweight loads. Do not overload.

4. Give a short run without adding moisture:

White Spirits (Petroleum solvent)... 10 to 15 minutes... or

Perchloroethylene............... .5 minutes......... or

Fluorocarbon.................... 5 minutes

5. Give normal extraction

6. Tumble dry. DO NOT EXCEED 120°F (50°C) TUMBLER TEMPERATURE!

7. Hang immediately. Do not leave in hamper.

CAUTION: If draperies are cabinet or air dried, do not place the coated side over the bar - place

the fabric side over the bar. If the drapery is damp with solvent or water and is folded

so that the coated side comes in contact with itself, the fabric may self-stick while

drying and then shred or tear the foam when separated.

DO NOT IRON THE ACRYLIC COATED SIDE OF THE LINING and only use a light cool iron on the

fabric side if necessary.
