A loopwheel machine rotates at just 24 revolutions per minute, a modern knitting machine in excess of 10 times that.  Each machine is only able to knit enough fabric for about 8 -10 shirts per day and can only knit a tube of a fixed diameter, so each size finished Tee or Sweat shirt is actually woven on a different sized machine. Apart from the knitted fabric feeling incredibly soft, it also allows shirts to be made with no side seams.  Sweats and tee’s made out of loopwheel fabric are necessarily expensive, but look better and last longer than anything else. \u0026lt;br \/\u0026gt;\n\u0026lt;br \/\u0026gt;\"\u003eloopwheeled\u003c\/span\u003e cotton fleece\u003c\/li\u003e\n\u003cli\u003eCrew neck\u003c\/li\u003e\n\u003cli\u003eFour needle, Union Special flat stitched seams\u003c\/li\u003e\n\u003cli\u003eSleeves are designed to be fairly tight, to avoid wind penetration\u003c\/li\u003e\n\u003cli\u003eOne washed, so minimal or no \u003cspan style=\"box-sizing: inherit; border-bottom-width: 1px; border-bottom-style: dotted; border-bottom-color: #212125; color: #212125; cursor: help; text-decoration: none;\" class=\"glossary_tooltip\" data-title=\"Yarns and\/or fabrics are not fixed materials. They consist of separate fibres that will stretch when exposed to tension, i.e. they elongate during the process of being made into cloth (during spinning, weaving, bleaching, dyeing and the various finishing processes, yarns and cloth are under continuous tension).  Some or all of this stretch within the fabric is retained in the post-loom fabric because of friction between the fibres and the yarns.\u0026lt;br \/\u0026gt;\n\u0026lt;br \/\u0026gt;\nThe stretch that occurs can be eliminated when the friction within the fabric is reduced.  This will happen during soaking and\/or washing, where both water and soap act as lubricants.  The lubricants, along with the mechanical action of the washer, help the fibres relax and contract (shrink) back to their original length. \u0026lt;br \/\u0026gt;\n\u0026lt;br \/\u0026gt;\nOne of the reasons that dry cleaning does not shrink natural fabrics is that the friction within the fabric is not reduced by dampening.\u0026lt;br \/\u0026gt;\"\u003eshrinkage\u003c\/span\u003e to be expected\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2444\/0699\/files\/ScreenShot2023-02-02at1.27.56PM_480x480.png?v=1675366107\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Iron Heart","offers":[{"title":"M","offer_id":44348649832755,"sku":null,"price":290.0,"currency_code":"USD","in_stock":true},{"title":"L","offer_id":44348649865523,"sku":null,"price":290.0,"currency_code":"USD","in_stock":false},{"title":"XL","offer_id":44348649898291,"sku":null,"price":290.0,"currency_code":"USD","in_stock":false},{"title":"XXL","offer_id":44348649931059,"sku":null,"price":290.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2444\/0699\/products\/E89A2666.jpg?v=1755114002","url":"https:\/\/www.ironshopprovisions.mom\/products\/14oz-ultra-heavyweight-loopwheel-cotton-crew-neck-sweat-olive","provider":"Iron Shop Provisions ","version":"1.0","type":"link"}
