Abstract
The invention provides a one-step scouring and bleaching method of jute roving. Roving is soaked in a scouring and bleaching solution, the bath ratio of the roving to the scouring and bleaching solution is 1:(10-20), stirring is performed, the mixture is heated to the temperature of 60-80 DEG C, and the temperature is maintained for 20-40 min; substances and concentrations of the substances in the scouring and bleaching solution are as follows: 4-6 g/L of hydrogen peroxide, 2-4 g/L of sodium hypochlorite, 1-2 g/L of sodium nitrate, 10-18 g/L of sodium hydroxide and 2-4 g/L of Turkey red oil; and the bath ratio of the roving to the scouring and bleaching solution is 1:15, the mixture is heated to 70 DEG C, and the temperature is maintained for 30 min. According to the provided one-step scouring and bleaching method of jute roving, scouring and bleaching processes are completed by one step, the technological process is shortened, the operation is simple, the cost is low, and at the same time, the possibility that fiber quality and performance deteriorate is greatly reduced.
Description
Technical field
The invention belongs to textile technology field, be specifically related to a kind of jute rove one step blanching method.
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.Jute output is abundant, cheap, has good antibacterial, mildew-resistant, the ecological, environmental protective characteristics such as uvioresistant, easy degraded.But in tossa, lignocellulose and hemicellulose level are higher, fiber is thick and stiff, elasticity and elongation at break are low, spinnability is poor, therefore common Jute thread and yarn is difficult to spinning, jute is mainly used to make gunnysack at present, the coarse product such as the rope made of hemp, the pigment of jute is many, chemicals-resistant stability is not as cotton fiber, its boiling and bleaching is also more difficult, to jute rove, be all to adopt first boiling at present, and then the step-by-step processing method of bleaching, step is many, and during step-by-step processing, digestion time is long easily makes the quality parameter of fiber worsen, then at bleaching, can cause irreversible damage to fiber, affect its later stage application.
Summary of the invention
For the problems referred to above, the invention provides a kind of jute rove one step blanching method, adopt one-step method to complete boiling and bleaching process, shortened process, greatly reduces fiber quality performance the possibility worsening occurs.
To achieve these goals, the technical solution used in the present invention is: a kind of jute rove one step blanching method, and rove is immersed in and is boiled in bleaching liquor, rove is 1:10 ~ 20 with the bath raio of boiling bleaching liquor, stirs, and is heated to 60 ~ 80 ℃, maintains 20 ~ 40min; Wherein saidly boil in bleaching liquor each material and concentration is: hydrogen peroxide 4 ~ 6 gL
-1, clorox 2 ~ 4 gL
-1, sodium nitrate 1 ~ 2 gL
-1, NaOH 10 ~ 18 gL
-1, turkey red oil 2 ~ 4 gL
-1.
Describedly boil in bleaching liquor each material and concentration is: hydrogen peroxide 5 gL
-1, clorox 3 gL
-1, sodium nitrate 1.5 gL
-1, NaOH 14 gL
-1, turkey red oil 3 gL
-1.
Rove is 1:15 with the bath raio of boiling bleaching liquor, is heated to 70 ℃, maintains 30 min.
Beneficial effect:
The invention provides a kind of jute rove one step blanching method, adopt one-step method to complete boiling and bleaching process, shortened process, simple to operate, reduce costs, greatly reduce fiber quality performance simultaneously the possibility worsening occurs.
The specific embodiment
Below in conjunction with embodiment, the present invention is further described.

-1, NaOH 10 gL
-1, turkey red oil 2 gL
-1.
Embodiment 2:
A jute rove one step blanching method, is immersed in rove to boil in bleaching liquor, and rove is 1:20 with the bath raio of boiling bleaching liquor, stirs, and is heated to 80 ℃, maintains 40min; Wherein saidly boil in bleaching liquor each material and concentration is: hydrogen peroxide 6 gL
-1, clorox 4 gL
-1, sodium nitrate 2 gL
-1, NaOH 18 gL
-1, turkey red oil 4 gL
-1.
Embodiment 3:
A jute rove one step blanching method, is immersed in rove to boil in bleaching liquor, and rove is 1:15 with the bath raio of boiling bleaching liquor, stirs, and is heated to 70 ℃, maintains 30min; Wherein saidly boil in bleaching liquor each material and concentration is: hydrogen peroxide 5 gL
-1, clorox 3 gL
-1, sodium nitrate 1.5 gL
-1, NaOH 14 gL
-1, turkey red oil 3 gL
-1.
Jute rove after embodiment 1 ~ 3 is processed carries out whiteness and the test of division degree, and result is as follows:
| Numbering | Embodiment 1 | Embodiment 2 | Embodiment 3 |
