UPHOLSTERY BACKING FAQs

1
What is FabBack ® Knit Backing?

FabBack ® Knit Backing is a process that adds strength, stability, and durability to fabric, making it suitable for use in upholstery or drapery.  It also makes the fabric easier to cut and sew, and more resistant to tears or damage due to seam slippage. We apply a layer of soft, pliable knit to the backside of the fabric, using proprietary methods that we have perfected over the last 20 years. Our processes do not alter the original color and appearance of your fabric.

2
Will knit backing affect the color of my fabric?

No, it will not. Our knit backing is available in off-white or black. For dark colored fabrics, we use the black backing. For light colored fabric, we use the off-white backing. This is the best way to reduce any color variation for lightweight or see through fabrics.

3
Is there a loss of yardage due to the knit or scrim backing process?

It varies with the fabric. We try to keep loss to a minimum. As a guideline, please allow 6 inches per roll plus ½ inch per yard for shrinkage and end waste. For example, with an 18 yard roll of fabric, the allowance for loss and shrinkage should be 15 inches. (Actual loss is usually much less)

4
What is FabScrim ® Scrim Backing?

FabScrim ® Scrim Backing is a woven poly / cotton fabric backing that is heat bonded to fabrics to provide strength, stability and body to the fabric. This backing is little heavier than and not as stretchable as knit backing. This is primarily used on open / loose weave fabrics.

5
What treatments do you recommend for draperies and pillows?

We suggest knit backing to enhance the stability, appearance, and durability of drapery and pillows. Knit backed fabric is more drapeable, allowing graceful pleats and falls. In many instances, knit backing can also eliminate the need for intermediate inner lining. To reduce fading due to sunlight, we recommend adding our UV protection finish. To keep your fabric looking clean and fresh, we suggest adding our stain protection finish.

My customer wants to use embroidered silk velvet to upholster a high chair. I cannot find anyone to knit back silks, embroidered fabrics or velvets, not to mention embroidered silk velvet. Can you help?

Yes, we can. We are different than everyone else. We routinely work with the finest silks, embroidered fabrics, and crushed velvets. Our engineers have carefully designed and perfected processes that minimize puckering, bonding separation, grain distortion, and pile crushing. Natural variations such as creases, wrinkles, uneven salvages, shadings, and distortions are corrected by our techniques, thereby improving the fabric's appearance. Your fabric will leave our workroom looking better than when it arrived. Conventional methods used by our competitors do not offer this level of care.

7
Will knit backing keep my fabric from fraying over time?

Yes, it will. Our knit backing is securely bonded to the back of the fabric. This keeps the fabric from fraying and provides stability, ease of cutting, body and resiliency.

8
My workroom has already cut and sewn the fabric into a finished slipcover, without realizing that the fabric was to be knit backed prior to fabrication. Can the finished slipcover be knit backed as is?

Yes, we can do that. Our custom fabrication department has successfully knit backed slipcovers or fabricated products. Please provide us with photos and a list of the pieces and sizes. We can then provide you with an estimated cost and timeframe for completion.

9
My great grandmother’s antique chair cushion covers are worn out and falling apart. I would like to restore them and keep them from further wear and tear. Can anything be done?

Yes, we can add our knit backing to antique fabrics, fabricated slip and cushion covers and drapes. Every case is different. Please provide us with photos and a list of the pieces and sizes. We can then provide you with an estimated cost and timeframe for completion.

10
I have a line of boutique handbags. I use fabric for inside lining of the bags. The lining needs to be sag free and wear resistant. Is there a way to improve performance?

Knit backing will improve stability, body as well as wear resistance of lined fabric.

11
I use animal skins to make wallets and handbags. Can you knit back animal skins?

We have successfully knit backed leather, snakeskins and exotic furs like alpaca and mohair. If you have any concerns about your specific case, please send us a sample for evaluation.

12
My project requires 108 inch wide fabric and no-seam construction for upholstering a lounge chaise. Can you knit back wide-width fabric?

We can back fabrics up to 120 inches wide. Please send us a photo and any other information you may have about your fabric. For extra wide fabrics, the roll size cannot exceed 10 yards. We can cut longer rolls into the appropriate sizes for you. For more information on extra wide fabric processing, please contact us.

My customer wants to upholster chairs / sofa with fine chenille fabric. My workroom wants the fabric to be acrylic backed. What do you recommend?

Knit backing is highly recommended for all upholstered fabric for stability, ease of cutting and sewing, seam slippage and less wear and tear on sewing equipment. Acrylic / latex backing is a liquid back coating that is applied to the back of the fabric and solidifies. This is not suitable for fabrics without DWR (durable water resistant) finish (moisture resistant) and silks because the coating can seep through and stain the face of the fabric. Unlike acrylic / latex, knit backing is a woven fabric which is applied to the back of the fabric using a heat-activated dry adhesive that does not penetrate through the fabric. Knit backed fabrics are also easier to cut and sew as compared to acrylic backed fabrics. This is because the acrylic / latex coating has the tendency to dull cutting edges and sewing needles due to its gummy nature. Therefore, more frequent maintenance of sewing equipment is often required when working with acrylic / latex as compared to knit backing.

Why do you prefer knit backing instead of acrylic / latex coating?

Unlike acrylic / latex, knit backing is a woven fabric which is applied to the back of the fabric using a heat-activated dry adhesive that does not penetrate through the fabric. Knit backed fabrics are also easier to cut and sew as compared to acrylic backed fabrics. This is because the acrylic / latex coating have the tendency to dull cutting edges and sewing needles due to its gummy nature. Therefore, more frequent maintenance of sewing equipment is often required when working with acrylic / latex as compared to knit backing.

I love hand-woven raw silk and want to reupholster my love seat with it. The silk fabric is highly textured and very loosely woven. My upholstery shop recommends acrylic back coating. What do you suggest?

We recommend scrim backing for all very loosely woven fabrics. Scrim backing is a woven fabric, which is more stable than knit backing. Scrim backing is thermally bonded to the fabric, while acrylic backing is a liquid coating. We do not recommend acrylic back coating for silk. Acrylic back coating will come through the loosely woven silk fabric and stain the face of fabric.

17
My project requires upholstering walls with fabric for an executive office suite. My concern is that fabric will tear or get distorted while pulling it on the foamboard. Is there a way to strengthen and stabilize fabric prior to stretching on the board?

Knit backing will provide the necessary strength and stability to maintain the integrity of fabric in stretching and anchoring on the board. It also makes the fabric easier to cut and sew, and more resistant to tears or damage due to seam slippage. We apply a layer of soft, pliable knit to the backside of the fabric, using proprietary methods that we have perfected over the last 20 years. Our processes do not alter the original color and appearance of your fabric.

I always line and interline my drapery panels, yet many times I am not satisfied with the look. Some fabrics just won’t drape well. Panels look droopy, saggy and without life. How can I improve the look?

Applying knit backing to the fabric prior to cutting and sewing will provide stability and crispness to the fabric. This will maintain the fresh look of the fabric and provide excellent drapeability over an extended period of time under various climatic conditions.

19
My drapery grew in length under its own weight by a few inches. I took it back to the workroom and got it hemmed to the correct length. However, after a few weeks it stretched a bit again. How do I avoid this costly rework?

Some fabrics can stretch under their own weight or under high humidity conditions. Knit backing the fabric prior to fabrication will stabilize the fabric as well as provide support to maintain the finished length. For loosely woven fabrics, we recommend scrim backing instead of knit backing.

20
I would like to use 12 oz. cotton canvas on a dining room chair. My concern is wear resistance due to excessive use.

Knit or scrim backing will enhance the wear resistance of the fabric. The extent of improvement varies with fabric and usage. In general, we can expect a 10% improvement in wear resistance.

21
Will the knit backing separate or come unglued with repeated wash cycles?

Knit backing is laminated at a much higher temperature than wash cycle temperatures and is designed to take multiple wash cycles without separation or deterioration.

22
We are looking for someone to back some raw silk for upholstered furniture. I was wondering if you use Formaldehyde-free glues when you back the fabric.

The adhesive used to bond our knit backing to your fabric is an environmentally safe, formaldehyde-free, odorless compound.

23
If we send striped or plaid fabric to you for knit backing, would the patterns come back to us as straight as they are right now?

We specialize in plaid, striped, silk, chenille and velvet fabrics. Most stripes and plaids have a small amount of waviness or bowing when we receive them. Our backing process compensates for this, and actually improves the skewing or bowing in the weave. It can never be removed completely.  If our inspection finds that your fabric has excessive bow or skew upon receipt, then we can advise you on your options at that time.
