Last week, I inspected a large commercial installation. The complaint came in as “loose tufts and snags”. What I found was something very different: sprouts.

As defined in my book, All About Carpets, “sprouts are long ends of yarns that protrude above the pile surface…Sprouting is a defect only if excessive and unserviceable.”

When I looked across the large, open, glued-down (no padding) installation, it appeared someone had dropped small ball bearings all over this tufted carpet. What I actually saw were random longer loops of carpet pile that were sticking up above the rest of the level loop pile. So what was going on? Had something yanked loops out of the carpet backing? Or was it something else?

Tufted carpet is made by using needles that stitch carpet yarns into a thin sheet of material. As many as 1,000 needles run across a width of carpet. Each needle sets a looped yarn at a predetermined height. For cut-pile carpet, a knife cuts (more…)

The carpet had not been cleaned yet. The renter, acting on the owner’s behalf, turned in a claim. I was asked to inspect the job for the manufacturer.

As I mentioned in my recent post on woven carpet, which only accounts for 2% of the carpets sold today, the majority of the carpets being purchased for residential homes is called tufted carpet.

Tufted carpet is manufactured using a giant sewing machine with as many as 1,200 needles. The spacing of the needles is one factor in determining the quality of the carpet, since the closer the needles, the tighter the yarn spacing stitched into the carpet backing and the heavier the fabric. But, this is just one factor.

These tufting machines are (more…)
