Abstract
The invention discloses a scouring and bleaching process of cotton-hemp blended rough yarn, which comprises the steps of pre-acid treatment, washing, rough yarn scouring and bleaching, washing, acid pickling and washing, wherein the step of scouring and bleaching comprises the following processes: impregnating the rough yarn after the pre-acid treatment and washing in scouring and bleaching liquid, wherein the bath ratio of the rough yarn to the scouring and bleaching liquid is 1:(15-25); performing program heating, wherein the start temperature is 20-25 DEG C, the heating speed is controlled at 2-4 DEG C per minute, the target temperature is set at 90-100 DEG C, and the target temperature is kept for 20-40 minutes; the scouring and bleaching liquid comprises the following substances: 3-6g/L hydrogen peroxide and 1-2g/L sodium nitrate; the pH value is adjusted to 10-11 with sodium hydroxide. The scouring and bleaching process of cotton-hemp blended rough yarn, disclosed by the invention, can obtain relatively high whiteness without reducing the strength of the cotton fiber while maintaining the good properties of cotton and hemp, so that the cotton-hemp blended rough yarn meets requirements for spinning.
Description
Technical field
The invention belongs to textile technology field, be specifically related to a kind of cotton ramie blended spinning roving boiling and bleaching process.
Background technology
Fiber crops are Cortical fibers of plant, and its function is approximate people's skin, has protection human body, regulate the natural performances such as temperature.Linen clothes can reduce the perspiration of human body than other dress material, and absorption speed is than silks and satins, rayon fabric, and even than cotton fast several times, form capillarity with skin contact, be the extension of skin.Flax yields poorly, expensive, by cotton and numb mixed textile, both advantages can be integrated, and obtains new high-grade fabric, greatly increases economic efficiency.Due to cotton and numb in fiber difference in essence, the pigment of fiber crops is many, chemicals-resistant stability is not as cotton fiber, its bleaching is also than cotton difficulty, make to be originally applicable to cotton boiling and bleaching process, be applicable to numb boiling and bleaching process originally for cotton ramie blended spinning rove inapplicable, need to consider the difference of two kinds of fibers, from boiling, float the selection of temperature-time, alkali consumption, bleaching agent and reformulate boiling and bleaching process.
Summary of the invention
For the problems referred to above, the invention provides a kind of cotton ramie blended spinning roving boiling and bleaching process, in the situation that keep cotton and fiber crops good characteristic separately, can obtain higher whiteness, do not damage again the brute force of cotton fiber, make cotton ramie blended spinning rove meet the requirement of spinning.
To achieve these goals, the technical solution used in the present invention is: a kind of cotton ramie blended spinning roving boiling and bleaching process, comprise pre-acid treatment, washing, roving boiling and bleaching, washing, pickling and water-washing step, wherein said boiling floated step and is: the rove after pre-acid treatment, washing is immersed in and is boiled in bleaching liquor, rove is 1:15 ~ 25 with the bath raio of boiling bleaching liquor, adopt temperature programming, initial temperature is 20 ~ 25 ℃, programming rate is controlled at 2 ~ 4 ℃/min, object temperature is arranged on 90 ~ 100 ℃, at object temperature, maintains 20 ~ 40min; Wherein saidly boil in bleaching liquor each material and concentration is: hydrogen peroxide 3 ~ 6 gL
-1, sodium nitrate 1 ~ 2 gL
-1, with NaOH, regulate pH to 10 ~ 11.
Describedly boil in bleaching liquor each material and concentration is: hydrogen peroxide 4 gL
-1, sodium nitrate 1.5 gL
-1, with NaOH, regulate pH to 10.5.
Programming rate is controlled at 3 ℃/min.
Object temperature is arranged on 95 ℃.
At object temperature, maintain 30min.
Rove is 1:20 with the bath raio of boiling bleaching liquor.
Beneficial effect:
The invention provides a kind of cotton ramie blended spinning roving boiling and bleaching process, in the situation that keep cotton and fiber crops good characteristic separately, can obtain higher whiteness, do not damage again the brute force of cotton fiber, make cotton ramie blended spinning rove meet the requirement of spinning.
