Carpet Problems and Solutions: Carpet High Lines

Carpeting is made using one of two methods: tufting or weaving. Almost all of the residential carpet sold today is made by tufting. Tufting machines are basically giant sewing machines. Instead of a single needle, 800-1,000 computer controlled needles stitch carpet yarns across a backing material to form the carpet. The needles are set to control the height of the carpet pile. Sometimes a single needle stitches a row of yarn that is too long. Cut pile carpets are carefully sheared after tufting in order to assure a smooth, even pile surface. Even so, a high row or high line can show up after a carpet is installed. If the high row is bent over and buried in the carpet pile, the line may take days or weeks to appear after the carpet has been repeatedly vacuumed. Tufting high lines always run lengthwise. (more…)

Common Carpet Defects: High Lines and Low Lines in Carpet

Thursday, April 17th, 2014

All kinds of lines appear in carpets. You can see some as soon as the carpet is rolled out; some don’t show up for several days or weeks. Some run lengthwise, others widthwise. Some can be removed, others can’t. Below is information on high lines and low lines in carpet. Future blogs will cover other common line flaw types, such as shear streaks, stop marks, shift marks, oil streaks and pattern bowing.

Lengthwise high lines or high rows in tufted cut pile carpets show up for a couple of different reasons. Carpets are sheared during the finishing process to produce an even pile height and texture. The shearing blades are like a reel lawn mower that runs the width of the carpet. If the blades are nicked, the carpet pile running under the damaged area comes out higher than the rest of the pile. Improperly set tufting needles can insert a row or rows of yarn that are too long. This happens with both cut and loop patterns. Sometimes the final shearing for cut piles misses these high rows. Loop carpets aren’t sheared, so the high rows stay in the roll until inspection. (more…)
