Description

Plant protein synthetic fiber spinning solution and production method thereof

One, technical field

The present invention relates to a kind of novel textile material spinning solution, especially a kind of plant protein is protein and ethanol sodium sulfonate and polyvinyl alcohol synthetic protein synthetic fibre spinning solution and the production method thereof in oily certain herbaceous plants with big flowers, sesame, tea seed, castor seeds, Endosperm Cocois, linseed oil and the rice bran.

Two, background technology

The protein fibre of known synthetic has dairy protein fiber, cortex collagenic protein fiber, hair matter keratin protein fiber, insects protein fibre, plant soybean protein fibre and animals and plants egg-pair white matter synthon.Its production technique of range protein fiber is more or less the same; That is to say that the range protein synthon all make various product costs produce differences with raw material sources and price, thereby also cause qualitative difference.At present, in life and the production a large amount of cheap plant slag, the dregs of rice are arranged, as the sunflower benevolence dregs of rice, sesame seed meal, the tea dregs of rice, the Semen Ricini dregs of rice, Endosperm Cocois, flaxseed meal and rice bran or the like, these slags, the dregs of rice generally are to handle as refuse, not only wasted a large amount of organism, but also polluted environment, have even become public hazards, how effectively to solve utilization of waste material, turn waste into wealth? this is that people need problem to be solved.

Three, summary of the invention

At above-mentioned situation, the present invention's purpose just provides plant protein synthetic fiber spinning solution and the production method thereof that a kind of new protein that utilizes plant slag, dregs of rice production is produced fiber spinning dope.Not only reduced the production cost of fiber, and solved an agricultural byproducts deep processing problem, turned waste into wealth, made full use of.

The present invention is achieved in that the plant protein 20-40 part by by weight, and ethanol sodium sulfonate 1-5 part and polyvinyl alcohol 59-75 part are made as raw material; Its method is with (the sunflower benevolence dregs of rice of purifying, sesame seed meal, leached tea oil slag, the Semen Ricini dregs of rice, Endosperm Cocois, protein in flaxseed meal and the rice bran etc.) any or any several blended protein, by concentration is 8-10%, pH value is 8-10, under condition of stirring, sulphite (the S-WAT that adds the 0.3-0.5% of protein wt on one side, potassium sulfite), slowly be warming up to 40-45 ℃ on one side, after treating that protein dissolves fully, when slowly being warming up to 60-75 ℃, the side chain modifier (hydrogen peroxide or peroxyformic acid or peracetic acid) that adds protein wt 1.5-3%, reacted 30-60 minute, when being warming up to 80-90 ℃ again, add 1-5 part acetate sodium sulfonate, insulation reaction 40-70 minute, when being warming up to 95-98 ℃ again, again with dissolve good polyvinyl alcohol water solution copolymerization together, add sodium bisulfite or the Potassium hydrogen sulfite of dry-matter gross weight 0.2-0.7% this moment, insulated and stirred reaction 90-120 minute is qualified spinning solution.Abundant raw material of the present invention, method is simple, and plant slag, the dregs of rice extract the protein prior art, technology maturation is easily produced plant protein, and, the protein fibre that the spinning solution that utilizes the present invention to realize is made, its performance not only has the intensity of chemical fibre, and has skin-friendly, water absorbability, the ventilation property of natural protein fibre, and is soft, gloss is soft, dyeability is excellent, and colour fastness is strong, the plurality of advantages that hot water resistance is good.Compare with the protein fibre of the synthetic that has gone on the market, raw material abundance and price are cheaper, and cost reduces greatly, compare with its natural protein fibre, not only have the advantage of intensity height, and fiber number is even, and fiber number and intensity can be controlled artificially, and producing becomes long filament.This spinning and aftertreatment technology and equipment performance and mature " egg-pair white matter synthon " reach " animal protein synthon " wet spinning technology and equipment performance basic identical, for this reason, fully can large-scale industrial production.And raw material is inexhaustible, and big economic benefit of tool and social benefit are arranged.

The present invention applies, and must make creative contribution for fiber sprinning.

Four, embodiment

Describe production method of the present invention in detail below in conjunction with explained hereafter flow process and example.

The plant that to purify (oily certain herbaceous plants with big flowers, sesame, tea seed, castor seeds, Endosperm Cocois, linseed oil, rice bran) protein 20-40 part can be the protein that any or its mixture constitutes earlier, dissolves respectively with polyvinyl alcohol.Get polyvinyl alcohol 59-759 part, concentration is controlled at 18-20%, slowly is warming up to 95-98 ℃, and the stirring that does not stop is until abundant dissolving; Get 20-40 part protein simultaneously, making concentration is 8-10%, pH value is 8-10, and adds S-WAT or the potassium sulfite of protein wt 0.3-0.5%, and stir on the limit, the limit slowly is warming up to 40-50 ℃, after treating that protein fully dissolves, when being warming up to 60-75 ℃ again, the hydrogen peroxide of adding protein wt 1.5-3% or peroxyformic acid or peracetic acid reaction 30-60 minute, when being warming up to 80-90 ℃ again, added 1-5 part ethanol sodium sulfonate insulation reaction 40-70 minute; When being warming up to 95-98 ℃ again, again with dissolve good polyvinyl alcohol solution blend together, add sodium bisulfite or the Potassium hydrogen sulfite of dry weight 0.2-0.7% this moment, insulation reaction 90-120 minute, is spinning property spinning solution preferably.Protein extracting method all adopts existing method.

Make after the above stoste, select mature protein, synthon wet method short fiber or wet method continuous yarn spinning technology and equipment for use, just this stoste spinning can be become the staple fibre and the long filament of various different sizes.

The consisting of of various compositions in this spinning solution: plant protein accounts for 20-40 part, and the ethanol sodium sulfonate accounts for 1-5 part, and polyvinyl alcohol accounts for 59-75 part, and subsidiary material comprise S-WAT or potassium sulfite; Hydrogen peroxide or peroxyformic acid or peracetic acid; They account for the 0.3-0.5% and the 1.5-3% of protein wt respectively, and sodium bisulfite or Potassium hydrogen sulfite account for the 0.2-0.7% of total dry matter weight.
