Embodiment 1
[0027] Flame-retardant viscose fiber and cotton fiber were respectively carded into slivers, and the slivers were blended according to the blending ratio of 20:80. After spinning, yarns with a yarn count of 15 tex and a twist of 700 twists / m were produced. Utilize the air-jet loom to weave the yarn to make a grammage of 150g / m 2 Plain weave. Prepare a dye bath in which the reactive dye concentration is 1% (o.w.f), the sodium sulfate concentration is 10g / L, and the sodium carbonate concentration is 5g / L, and the bath ratio is 1:10. Dyeing was carried out at 50°C, and the dyeing time was 40min. According to the GB 5454-198 test standard, the limiting oxygen index of the dyed fabric is 28%.
Embodiment 2
[0029] Flame-retardant viscose fiber and cotton fiber were respectively carded into slivers, and the slivers were blended according to the blending ratio of 30:70. After spinning, yarns with a yarn count of 20 tex and a twist of 800 twists / m were produced. Utilize the air-jet loom to weave the yarn, and the grammage is 180g / m 2 Twill fabric. Prepare reactive dye concentration as 2% (o.w.f), sodium sulfate concentration as 15g / L, sodium carbonate concentration as the dye bath of 10g / L, bath ratio is 1:20. Dyeing was carried out at 50°C, and the dyeing time was 50 minutes. According to the GB 5454-198 test standard, the limiting oxygen index of the dyed fabric is 29%.
Embodiment 3
[0031] Flame-retardant viscose fiber and cotton fiber were carded into slivers respectively, and the slivers were blended according to the blending ratio of 40:60. After spinning, yarns with a yarn count of 20 tex and a twist of 800 twists / m were produced. Utilize the air-jet loom to weave the yarn, and the grammage is 180g / m 2 Plain weave. Prepare a dye bath in which the direct dye concentration is 2% (o.w.f), the sodium sulfate concentration is 15g / L, and the sodium carbonate concentration is 10g / L, and the bath ratio is 1:20. Dyeing was carried out at 50°C, and the dyeing time was 50 minutes. According to the GB 5454-198 test standard, the limiting oxygen index of the dyed fabric is 29%.
