That\u2019s why manufacturers, parts suppliers, rack fabricators, and logistics teams want rack bags where the seams won\u2019t rip. Sometimes, however, seam failure happens when there\u2019s no damage to the fabric dunnage itself. By understanding why this happens, you can make better design decisions.<\/p>\n<p>The seams on parts bags can fail for many reasons, but there are four that relate to threads and stitching.<\/p>\n<ul>\n<li>Thread type<\/li>\n<li>Thread weight<\/li>\n<li>Stitch count<\/li>\n<li>Stitch type<\/li>\n<\/ul>\n<p>Let\u2019s take a look at each one.<\/p>\n<h2>Thread Type<\/h2>\n<p>Using the wrong type of thread is a common mistake. That\u2019s why it\u2019s important to compare the rack bag environment to a thread\u2019s material properties. If you\u2019re designing sewn fabric dunnage that will be stored outdoors, remember that polyester thread offers greater weather resistance than cotton. Nylon thread is tough and durable, but will degrade when exposed to sunlight. Consider <a href=\"https:\/\/hold-true.com\/2017\/04\/fabric-dunnage-costs\/\">rack bag cleaning<\/a>, too.<\/p>\n<h2>Thread Weight<\/h2>\n<p>Choosing the wrong thread weight can also cause seam failure. Thicker threads cost more, but they\u2019re stronger. Thinner threads are lighter and less durable, but they cost less. Spools of thinner threads contain longer lengths, too. They\u2019re easier to trim and may work well with a lighter-duty sewing machine, but using a lighter thread isn\u2019t a bargain if your <a href=\"https:\/\/hold-true.com\/2017\/04\/rack-bag-design\/\">rack back design<\/a> requires greater strength.<\/p>\n<h2>Stitch Count<\/h2>\n<p>Industrial sewing machines support a range of stitch counts. Because each stitch has an individual strength, increasing the number of stitches per inch increases the seam strength. In other words, a seam with 10 stitches per inch is stronger than a seam with 2 stiches per inch. More isn\u2019t always better, however, and it\u2019s possible to have too much of a good thing.<\/p>\n<p>Stitching puts tiny holes into the base material. Because each stitch needs a hole for a knot, rack bags with more stiches have more holes. This can weaken the base fabric and allow sewn fabric dunnage to tear even when the seams remain intact. To avoid this problem, designers need a <a href=\"https:\/\/hold-true.com\/2017\/05\/fabric-dunnage-suppliers\/\">fabric dunnage supplier<\/a> who can strike the right balance for stitch count.<\/p>\n<h2>Stitch Type<\/h2>\n<p>Lock stitches require a bobbin. With industrial sewing machines, these bobbins are large and time-consuming to change. Chain stitches offer an alternative, but it\u2019s important to use lock stitches with sewn fabric dunnage. Otherwise, your rack bag\u2019s seams can unravel. Lock stitching isn\u2019t all you\u2019ll need, however. When you use a lock stitch, use proper <a href=\"http:\/\/www.threadsmagazine.com\/item\/15750\/sewing-terms-to-know\/page\/all\">back-tacking<\/a> to avoid having a single point failure.<\/p>\n<h2>Choose Sewn Fabric Dunnage from Hold-True<\/h2>\n<p>Hold-True, maker of <a href=\"https:\/\/hold-true.com\/2017\/05\/sewn-fabric-dunnage-costs\/\">Made in the USA fabric dunnage<\/a>, supports rack back design by helping you choose the right thread type and thread weight.
