Embodiment 1

[0020] Organic hemp is made into hemp sliver, drawn and combined by five or more drawing processes, and then drawn, wound and twisted to make roving. The roving is scoured and bleached, which includes four processes: biological additive L treatment, alkali boiling, oxygen bleaching, and biological additive D treatment:

[0021] Bio-aid L treatment: PH = 7-8, L: 9g / L, JFC: 1g / L, temperature: 55°C, treatment for 75 minutes; alkaline cooking: alkalinity 10g / L, of which NaOH3g / L, NaOH 2 CO 3 19g / L, treat at 95°C for 60 minutes, then wash with water at 85°C for 15 minutes; oxygen bleaching: PH=10.5, add H 2 o 2 : 10.5g / L (30%), Na 2 SiO 3 : 10g / L, JFC: 6g / L, take 30-40 minutes to heat up to 100°C, keep warm for 60 minutes, then wash twice with cold water; treat with an appropriate amount of biological aid D at 40-50°C for 10 minutes. After boiling and bleaching, it is drawn, twisted and spun into a spun yarn, then dried and wound into a bobbin yarn.

Embodiment 2

[0023] Organic hemp is made into hemp sliver, drawn and combined by five or more drawing processes, and then drawn, wound and twisted to make roving. The roving is scoured and bleached, which includes four processes: biological additive L treatment, alkali boiling, oxygen bleaching, and biological additive D treatment:

[0024] Bio-auxiliary L treatment: PH=7-8, L: 8g / L, JFC: 1g / L, temperature: 55°C, treatment for 60-90 minutes; alkaline cooking: alkalinity 10g / L, of which NaOH4g / L, Na 2 CO 3 16g / L, treat at 95°C for 60 minutes, then wash with water at 85°C for 15 minutes; oxygen bleaching: PH=10, add H 2 o 2 : 12g / L (30%), Na 2 SiO 3 : 10g / L, JFC: 6g / L, take 30-40 minutes to heat up to 100°C, keep warm for 60 minutes, then wash twice with cold water; treat with an appropriate amount of biological aid D at 40-50°C for 10 minutes. After boiling and bleaching, it is drawn, twisted and spun into a spun yarn, then dried and wound into a bobbin yarn.

Embodiment 3

[0026] Organic hemp is made into hemp sliver, drawn and combined by five or more drawing processes, and then drawn, wound and twisted to make roving. The roving is scoured and bleached, which includes four processes: biological additive L treatment, alkali boiling, oxygen bleaching, and biological additive D treatment:

[0027] Bio-aid L treatment: PH = 7-8, L: 10g / L, JFC: 1g / L, temperature: 55°C, treatment for 75 minutes; alkaline cooking: alkalinity 10g / L, of which NaOH 5g / L, NaOH 2 CO 3 13g / L, treat at 95°C for 60 minutes, then wash with water at 85°C for 15 minutes; oxygen bleaching: PH=10.5, add H 2 o 2 : 13g / L (30%), Na 2 SiO 3 : 10g / L, JFC: 6g / L, take 30-40 minutes to heat up to 100°C, keep warm for 60 minutes, then wash twice with cold water; treat with an appropriate amount of biological aid D at 40-50°C for 10 minutes. After boiling and bleaching, it is drawn, twisted and spun into a spun yarn, then dried and wound into a bobbin yarn.

Abstract

The invention discloses an ecological flax yarn and a manufacturing process thereof. The ecological flax yarn is made of organic ramie as a raw material with particularly high main technical indexes; the manufacturing process of the ecological flax yarn comprises the following steps: manufacturing the organic ramie into ramie stripes; drawing and joining by five or more drawing procedures, then drawing, winding and twisting to form rove; and boiling, bleaching the rove, then spinning to spun yarn; drying and coning to form yarn cones. The boiling and bleaching agent of the ecological flax rove consists of a biological assistant L, caustic soda NaOH, soda Na2CO3, sodium silicate Na2SiO3, hydrogen peroxide solution H2O2 and a biological assistant D; the flax yarn has the beneficial effects that the flax yarn has ecological indexes meeting Technical Requirement for Environmental Textile, and the ecological flax yarn has low hairiness, good yarn evenness, high flexibility, softness and luster.

Description

technical field [0001] The invention relates to an ecological flax yarn, and also relates to a manufacturing process of the ecological flax yarn. Background technique [0002] In order to remove part of the pectin, lignin, pigment and nitrogen-containing impurities in the flax roving, most of the existing domestic flax spinning mills adopt the sub-oxygen bleaching process for the roving bleaching. The choice of this process is obviously to increase the degree of splitting of fibers, which is beneficial to spinning processing. The specific steps of the process are: pickling, sub-bleaching, cold water washing, constant flow water washing, oxygen bleaching, hot water washing, cold water washing and room temperature washing. In the sub-bleaching process of the process, sodium chlorite is usually used as a bleaching agent. Because this substance is a strong oxidant, it is not only flammable and explosive, but also generates a lot of chlorine dioxide during use. Therefore, the ...
