Abstract

The invention mainly discloses a method for opening seamless knitted underwear. The method comprises the steps of: knitting and pretreatment, namely, adding hot-melted yarns for knitting at an opening position, and naturally spreading or hanging the knitted open seamless underwear for steaming, wherein the steaming treatment aims to make the hot-melted yarns completely melted before dyeing and bond the hot-melted yarns with the other yarns interleaved with the hot-melted yarns to fix a coil due to the bonding and further prevent laddering and missed stitches. An effective knitting method for preventing the laddering and the missed stitches after knocking over and opening comprises a pretreatment process and a dyeing process, can prevent the missed stitches of the obtained product, solves a major problem of opened fabrics and greatly improves the quality of the fabrics.

Description

technical field [0001] The invention relates to a method for seamless knitting underwear to pass through loop openings at any position without falling apart and without missing stitches, and belongs to the technical fields of knitting, pretreatment and dyeing. Background technique [0002] The needle-off opening of existing knitted fabrics is stretched horizontally or vertically, or in the process of wearing movement, the opening will produce loops in the opposite direction of the knitting direction, causing missing stitches, and the more the leakage is, the more the leakage is. Many, affecting the quality of the product, resulting in the consequences of customer complaints. Contents of the invention [0003] The purpose of the present invention is to provide an opening method for seamless knitted underwear, an effective knitting method that does not loosen stitches and does not miss stitches after stripping and opening, and includes pretreatment and dyeing processes, so t...
