Embodiment 1

[0034] A kind of zein viscose filament manufacture method is characterized in that, main steps comprise:

[0035] A. Preparation of zein liquid: take a certain amount of zein, dissolve the zein in an aqueous solution of sodium hydroxide with a concentration of 1% at a temperature of 20°C, and filter to obtain a zein solution; The concentration of the product is 1%, and the filtration adopts ordinary filtration, mainly to filter the impurities, because some impurities may be brought in during the production process, or the raw materials themselves have impurities.

[0036] B. Blending of zein liquid and viscose liquid: After defoaming the zein liquid and viscose liquid respectively, the zein liquid accounted for 1% and the viscose liquid accounted for 99% of the static at 15°C. Mix evenly and defoam again to obtain zein spinning solution.

[0037] The defoaming process is a conventional method, the viscose liquid includes cellulose sulfonate, alkali and water, and the static m...

Embodiment 2

[0044] A kind of zein viscose filament manufacture method is characterized in that, main steps comprise:

[0045] A. Preparation of zein liquid: take a certain amount of zein, dissolve the zein in an aqueous sodium hydroxide solution with a temperature of 80°C and a concentration of 15%, and filter to obtain a zein solution; after dissolving, the zein in the zein solution The concentration is 10%.

[0046] B. Blending of zein liquid and viscose liquid: After defoaming the zein liquid and viscose liquid separately, the zein liquid accounted for 10%, and the viscose liquid accounted for 90% of the ratio, and statically carried out at 25°C Mix evenly and defoam again to obtain zein spinning solution.

[0047] C. Spinning: Wet spinning is adopted, and the zein spinning solution is sent into the spinning machine through the rubber supply pipeline, and is sent into the spinning machine by a metering pump, and the particle impurities are filtered out again through the candle filter,...

Embodiment 3

[0051] A kind of zein viscose filament manufacture method is characterized in that, main steps comprise:

[0052] A. Preparation of zein solution: take a certain amount of zein, dissolve the zein in an aqueous sodium hydroxide solution with a temperature of 100°C and a concentration of 20%, and filter to obtain a zein solution; after dissolving, the zein in the zein solution The concentration is 30%, and the filtration adopts ordinary filtration, mainly to filter the impurities, because some impurities may be brought in during the production process, or the raw materials themselves have impurities.

[0053] B. Blending of zein liquid and viscose liquid: After defoaming the zein liquid and viscose liquid separately, the zein liquid accounted for 20% and the viscose liquid accounted for 80% at 30°C. Mix evenly and defoam again to obtain zein spinning solution.

[0054] The defoaming process is a conventional method, the viscose liquid includes cellulose sulfonate, alkali and wa...

Abstract

The invention relates to a method for manufacturing textile industrial materials, in particular to a method for manufacturing corn protein viscose filaments. The method utilizes a corn protein spinning solution and a cellulose sulphonate colution to perform static mixing and injection before spinning and accordingly achieves filament spinning. The method mainly comprises the steps of A, preparing a corn protein solution; B, mixing the corn protein solution and viscose liquid; C, spinning; D, performing solidification and curing; and E, performing postprocessing, namely performing acid-washing, desulfuration, washing, acid-washing, washing, oiling, dehydration and drying to fiber bundles to obtain the corn protein viscose filaments. The method has the advantages that the corn protein viscose filaments manufactured by means of the raw materials and the method according to the proportion, the temperature, the concentration and a technological process is soft and bright yellow. Compared with the prior art, the method for manufacturing the corn protein viscose filaments is simple in process and convenient to operate.

Description

technical field [0001] The present invention relates to a manufacturing method of textile industrial materials, specifically a kind of zein viscose that uses zein spinning solution and cellulose sulfonate solution for static mixing and pre-spinning injection to realize spinning Filament manufacturing method. Background technique [0002] At present, zein is mainly used in food additives, cosmetic additives, and co-polymerization with regenerated cellulose fibers and synthetic fibers, and then spinning to obtain a new textile material. Corn protein fiber is based on viscose, which retains the characteristics of viscose fiber. At the same time, it contains a large amount of zein. Similar, with good textile properties. [0003] The development of corn protein used in new textile materials mainly focuses on the copolymerization with regenerated cellulose fiber and synthetic fiber at the present stage, and the patent document disclosed for the mixed spinning with regenerated ce...
