Recommended Cleaning and Care of Stage Curtains

For 100% IFR Polyester

We manufacture polyester velvet and velour as inherently flame retardant (IFR 100% polyester) material that will be flame retardant for the life of the curtains. It never needs to be re-treated but will require some maintenance (cleaning) from time to time through the life of the curtain, depending on the conditions in which the curtains are hanging.

A light vacuuming with a soft brush to get the dust out is highly recommended. This will help the curtain stay fresh and keep airborne pollutants such as dust and allergens out of your curtains. Over time you may need to have curtains dry-cleaned by a professional cleaning service. But after cleaning, they will not need to be retreated for flame retardance.

For 100% Cotton

Flame retardant treated material (100% cotton) should be dry cleaned by a professional cleaning service for worst-case situations such as high humidity or extreme low humidity and or unusual amounts of dust. These conditions can affect the flammability of stage curtains over a period of time. Cotton stage curtains will need to be retreated after dry cleaning.

Some tips to help stage curtains last longer between dry cleanings: do a light vacuuming with a soft brush, and keep the stage and surrounding areas as clean and dust-free as possible.

For All Stage Curtains

Whether your stage curtains are 100% IFR polyester or 100% cotton, you should periodically field-test them for flame-retardant performance, because wide fluctuations in atmospheric humidity as well as accumulations of airborne dust and oils can diminish the endurance and the effectiveness of the flame-retardant chemical. Our fabrics should last for many, many years, but fabric performance will vary based on environmental conditions.

We suggest an annual field test of cotton stage curtains to confirm flame-retardant performance (NFPA 705 Field Test Method for Textiles). Cotton velvet is a very delicate fabric, and the pile can easily be disturbed. But with careful handling and a real understanding of its nature, cotton velvets can be enjoyed for many, many years to come. Newly made drapes will need time to condition to the atmosphere in which they are installed. It will take time for the pile to relax and lift, which improves the richness and the luster of the velvet.

Product Testing

Our drapery and stage curtain fabrics are flame-retardant and tested using the NFPA standard. Our velvet and velour products are all NFPA 701 compliant under the 2010 Test Method 1. We also test and meet standards set forth by Canada, California, New York, and other municipalities.

Textiles the KM Way

Normally, when someone thinks of textile manufacturing, what comes to mind is the mass production of common everyday items such as clothing and bedding. But that’s not the case with KM Fabrics.

KM Fabrics purchases the finest quality natural and synthetic yarns to produce velvet fabrics. Velvet weaving involves the weaving of two pieces of fabric simultaneously. Pile warp yarns are woven into ground warps, and then cut to produce the raised effect. Once cut, the two pieces of fabric are wound on separate take-up rolls.

At KM, pressurized and atmospheric dye machines are used to dye velvet fabrics. Velvets produced from synthetic yarns (polyester) are dyed in machines under extreme heat and pressure to help penetrate the fabric deeply and evenly. Fabrics made from natural fibers (cotton) are dyed in open atmospheric machines.

Once dyed, fabrics are open width dried and then finished according to end use. The finishing process may involve the application of flame retardant, latex backing, or soil repellant. Velvets then go through the final finishing process of brushing to position the pile and (if required) sheering the fabric face.

After finishing, the velvet fabric is wound onto large A-frames, and then 100% inspected and prepared for shipping.
