Problems solved by technology

At present, people usually use the conventional dyeing and finishing process to produce colored fibers for the coloring treatment of flame-retardant fibers. Cause problems such as uneven color and poor color fastness, increase energy consumption, manpower and cost, and produce waste water to pollute the environment
Moreover, in the dyeing and finishing process of flame-retardant fibers, due to the action of dyeing and finishing agents, the effective flame-retardant ingredients in the fibers are gradually lost along with the dyeing and finishing process, which gradually reduces the flame-retardant effect of the fibers and affects the flame-retardant effect of the fibers.

Embodiment 1

[0017] First, take sodium hexapolyphosphate or sodium tripolyphosphate and heat and dissolve it in 20g / l of dilute lye. Then, according to the coloring requirements of fiber production, mix the two evenly according to the ratio of sodium hexapolyphosphate to 2% of the weight of the color paste. After 2 hours, the colorant is prepared;

[0018] Secondly, cellulose cotton pulp is used to prepare cellulose xanthate by conventional short cellulose production method, and cellulose xanthogenate, silicon dioxide, sodium hydroxide and water are mixed uniformly to prepare a blended viscose liquid; The obtained blended viscose liquid is gradually matured by dissolving, filtering, and defoaming, and adding coloring agent in the dissolution to prepare a blended spinning dope, so that the weight content ratio of the prepared spinning dope is: α-fiber Element 5.0%, silicon dioxide 40% (for α-cellulose), sodium hydroxide 10.5%, colorant (calculated as solids) 3.4% (for α-cellulose), and moisture...

Embodiment 2

[0022] First, take sodium hexapolyphosphate or sodium tripolyphosphate and heat and dissolve it in 110g / l dilute lye. Then, according to the coloring requirements of fiber production, mix the two evenly according to the proportion of sodium tripolyphosphate accounting for 4% of the weight of the color paste. The colorant is prepared after 3 hours of mixing time;

[0023] Secondly, cellulose wood pulp is used to prepare cellulose xanthate by the conventional short cellulose production method, and cellulose xanthate, silicon dioxide, sodium hydroxide and water are mixed uniformly to prepare a blended viscose liquid; The obtained blended viscose liquid is gradually matured by dissolving, filtering, and defoaming, and the coloring agent is added before the viscose defoaming to prepare a blended spinning dope, so that the weight content ratio in the spinning dope is: α-fiber Element 8.0%, silica 60% (for α-cellulose), sodium hydroxide 10.2%, colorant (calculated as solids) 5.5% (for α-...

Embodiment 3

[0027] First, take sodium hexapolyphosphate or sodium tripolyphosphate and heat and dissolve it in 40g / l of dilute lye. Then, according to the coloring requirements of fiber production, mix the two evenly according to the ratio of sodium tripolyphosphate to 2.5% by weight of the color paste. After 2 hours, the colorant is prepared;

[0028] Secondly, cellulose cotton pulp is used to prepare cellulose xanthate by conventional short cellulose production method, and cellulose xanthogenate, silicon dioxide, sodium hydroxide and water are mixed uniformly to prepare a blended viscose liquid; The obtained blended viscose liquid is gradually matured by dissolving, filtering, and defoaming, and the coloring agent is added before the viscose defoaming to prepare a blended spinning dope, so that the weight content ratio in the spinning dope is: α-fiber Element 7.5%, silicon dioxide 20% (for α-cellulose), sodium hydroxide 10.5%, colorant (calculated as solids) 3.0% (for α-cellulose), and mois...

Abstract

The invention relates to the cellulose and colored silica fiber composites and the processing method. Process the spinning liquid glue from cellulose xanthate, silica, sodium hydroxide and water. Add colorants in and mix them to be colored liquid viscose. This colored fiber composites with a permanent fire flame retardant, has high color fastness, widely chromatogram, dyeing equably, and cost cheaply. It can be used in color spinning so that to avoid staining processes and Reduce environmental pollution and the waste of energy.

Description

Technical field [0001] The invention relates to a fiber production technology, in particular to a manufacturing method for producing composite colored fibers using cellulose and silicon dioxide. Background technique [0002] Cellulose viscose fiber is made from cellulose after a series of chemical treatments. Because of its good moisture absorption and air permeability, it has been widely used in clothing, household products, medical and health and other fields, and people have modified it or added functional additives to produce functional fibers, such as those prepared by adding silicon-based substances. Flame retardant fiber. At present, people usually use conventional dyeing and finishing processes to produce colored fibers for the coloring treatment of flame-retardant fibers. This production method not only has high production costs, but also due to fiber quality and craftsmanship during the dyeing process. Causes uneven color, poor color fastness and other problems, increas...
