勝家 Singer 2045 圓頭/彈性縫紉機針

Singer 2045 是專為針織布料、合成纖維布料及彈性布料設計的縫紉機圓頭針（ballpoint needle）。
防跳針設計：針柄經過特殊設計，尺寸略小，能使針身的凹槽（scarf）更靠近縫紉機的旋梭/擺梭，從而有效防止在縫製彈力材料時出現跳針現象。
70/10 與 80/12 ：最適合細薄針織布料、平紋針織布（jersey）及氨綸（spandex）布料。
90/14 ：非常適合中等厚度的彈性布料及雙面針織布。
100/16 與 110/18 ：專為厚重針織布料以及較厚的彈性抓絨或毛衣針織布料設計。
Singer 2045 needles are ballpoint sewing machine needles designed specifically for knit, synthetic, and stretch fabrics.
Anti-Skip Design: The shank is engineered slightly smaller to position the needle's scarf closer to the machine hook, effectively preventing skipped stitches on elastic materials.
Size 70/10 & 80/12: Best for fine or lightweight knits, jerseys, and spandex.
Size 90/14: Ideal for medium-weight stretch fabrics and double knits.
Size 100/16 & 110/18: Built for heavy-weight knits and thicker stretch fleece or sweater knits.
