Embodiment 1

[0034] A method for manufacturing zein viscose staple yarn, characterized in that the main steps include:

[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 ...

Embodiment 2

[0044] A method for manufacturing zein viscose staple yarn, characterized in that the main steps include:

[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 method for manufacturing zein viscose staple yarn, characterized in that the main steps include:

[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 w...

Abstract

The invention relates to a manufacture method of spinning industry materials, in particular to a manufacture method of corn protein viscose staple fibers, which realizes the spinning through utilizing corn protein spinning solution and cellulose sulphonate solution to carry out static mixing and spinning injection. The manufacture method mainly comprises the steps of A, corn protein liquid preparation; B, corn protein liquid and viscose liquid blending; C, spinning; D, solidification and curing; and E, post treatment. Fiber beams are subjected to cutting, acid washing, desulfuration, water washing, acid washing, water washing, oiling, dehydration and drying, and then, corn protein viscose staple fibers are obtained. The manufacture method has the advantage that the corn protein viscose staple fibers manufactured by raw materials according to the proportion, the temperature, the concentration and the process flow in the method have soft filament strips and bright yellow color and luster. Compared with the prior art, the production method for producing the corn protein viscose filaments has the advantages that the process is simple, and the operation is convenient.

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 Short 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 regenera...
