Regenerated environmental-friendly yarn label strap and manufacturing method thereof

The invention relates to a label strap and a manufacturing method of the label strap, in particular to a regenerated environmental-friendly yarn label strap and a manufacturing method of the regenerated environmental-friendly label strap. The thickness of the label strap is 0.11-0.15mm, the hardness is 2.8-3.7, and the gram weight is 120-180g/m ; base cloth is made of PET material, the specification of yarns for manufacturing the base cloth is 50-150D, the warp density is 90-130 roots/cm, and the weft density is 36-45 roots/cm. The manufacturing method includes the step of beaming, slashing and weaving, the step of pretreatment for dyeing and finishing; the step of dyeing, the step of sizing in a continuous and segmented mode, the step of calendering for the first time at the temperature of 150-170 DEG C, pressure of 5-15MPa and speed of 5-15m/min, the step of calendering for the second time at the temperature of 190-210 DEG C, pressure of 10-15MPa and speed of 10-16m/min and the step of slitting. The manufactured regenerated environmentally-friendly yarn label strap functionally defined to be suitable for a double-faced TTR hot transfer printing mode, the color fastness to soaping meets the GB/T3921 textile color fastness test standard, environmental requirements meet the OEKO-TEX primary standard, and the label strap is suitable for dry ink printing and wet ink printing modes.
