Abstract
The invention discloses a jute fiber degumming process. The jute fiber degumming process mainly comprises the following steps of raw jute cleaning, raw jute pickling, rinsing, primary alkali-hydrogen peroxide bathing, raw jute beating, rinsing, acid pickling, washing and airing. Jutes are degummed and bleached by using the primary alkali-hydrogen peroxide bathing method, the alkali and hydrogen peroxide are mutually acted, the alkali removes gum, hemicelluloses, xylogen and other impurities in jute fibers and also provides an alkali environment for the decomposition of hydrogen peroxide; hydrogen peroxide is very stable in an acid medium, and the decomposition velocity is very low; however, hydrogen peroxide can be activated in an alkali medium, and hydrogen peroxide molecules are decomposed to bleach the jute fibers. Simultaneously, and particularly importantly, the xylogen can be oxidized, and the oxidized xylogen can be dissolved in high-temperature strong aqueous alkali under experiment conditions, so that the removal of the xylogen is facilitated.
Description
Technical field
The invention belongs to field of fabric producing technology, be specifically related to a kind of tossa degumming tech.
Background technology
The main component of tossa is cellulose, hemicellulose and lignin.Tossa has higher intensity and hygroscopicity, is the good insulator of heat and electricity, is most easily biological-degradable in natural fabric, does not produce toxic gas when its degraded or burning.Along with the development of jute machinery, chemical processing technology, fui and the fabric with other fiber blends thereof can be spinned, the feel that jute is thick and stiff simultaneously have also been obtained improvement, makes this kind fabric have larger development potentiality at multiple fields such as fashionable dress, duffel bag, carpet, woollen blankets.The quality of crudefiber crop textile product quality, depends primarily on coming unstuck of fiber crops.For a long time, raw ramie comes unstuck and continues to use aging process and chemical method carries out always.Natural law is come unstuck greatly affected by environment, and expend time in length, containing assorted many, and difficult quality guarantee; The chemical degumming law energy consumption that present factory commonly uses is high. and overlong time, cause unnecessary damage, and cost is high to fiber.
Summary of the invention
The object of the invention is to, provide a kind of tossa degumming tech, solve the greatly affected by environment of existing jute degumming technology existence, expend time in length, and containing assorted many, difficult quality guarantee, easily causes damage to fiber, high in cost of production problem.
Tossa degumming tech provided by the invention, it comprises following processing step:
A. the large impurity in manual removing raw ramie;
B. raw ramie pickling: temperature 40-50 DEG C, time 55-65min, bath raio is 1: 15-20, acid solution mass concentration: 0.8-1ml/L;
C. wash: with tap water to pH=7;
D. alkaline oxygen bath: normal pressure, bath raio is 1: 15-20, MgS0
47H
20 mass concentration is 0.08-0.1%, and temperature controls in the pre-temperature rise period, and programming rate controls at 1-1.2 DEG C/min;
E. fiber crops are struck;
F. wash: with the water punchings of more than 60 DEG C to pH=7;
G. pickling: add sulfuric acid 1-2g/L, weight bath raio 1: 10-20, keeps draining after 5-10 minutes under room temperature;
H. normal temperature washing, finally dries.
Tossa degumming tech provided by the invention, its beneficial effect is: alkali and the hydrogen peroxide one-bath one-step dyeing of employing carry out degumming and bleaching to jute, alkali and hydrogen peroxide interact, alkali had both played the effect of colloid, hemicellulose, lignin and other impurity removed in tossa, again for the decomposition of hydrogen peroxide provides an alkaline environment; Hydrogen peroxide is very stable in acid medium, and decomposition rate is very low, and can be activated by alkali in alkaline medium, hydrogen peroxide molecule generation dissociation, can bleach tossa.Simultaneously significantly can oxidative lignin, can be dissolved in after lignin is oxidized in high temperature aqueous alkali in experiment condition, thus contribute to better removing lignin.
Detailed description of the invention
Below in conjunction with an embodiment, tossa degumming tech provided by the invention is described in detail.
Embodiment
The tossa degumming tech of the present embodiment, it comprises following processing step:
A. the large impurity in manual removing raw ramie;
B. raw ramie pickling: temperature 45 C, time 60min, bath raio is 120, acid solution mass concentration: 1ml/L;
C. wash: with tap water to pH=7;
D. alkaline oxygen bath: normal pressure, bath raio is 1: 20, MgS0
47H
20 mass concentration is 0.1%, and temperature controls in the pre-temperature rise period, and programming rate controls at 1 DEG C/min;
E. fiber crops are struck;
F. wash: with the water punchings of more than 60 DEG C to pH=7;
G. pickling: add sulfuric acid 1g/L, weight bath raio 1: 20, keeps draining after 8 minutes under room temperature;
H. normal temperature washing, finally dries.
