Abstract
The invention which provides a pressure washing technology suitable for the refinement of a protein viscose filament belongs to the viscose filament production field in the textile industry. The technology aims to solve problems of low strength, easy powder dropping, nonuniform dyeing, and environment pollution of protein fibers in the prior art, wherein the problems are caused by the dissolving and the shedding of proteins on the protein fibers in an alkali washing step in the pressure washing flow. By improving the water washing technology, the pressure washing of the protein fiber viscous filament can be effectively carried out, and the finished protein viscose filament has the advantages of high strength, difficult powder dropping, uniform dyeing, and no pollution to environment.
Description
Technical field
The present invention relates to a kind of refinery practice of viscose filament yarn, more particularly, the present invention relates to a kind of technology of compressing and washing that is applicable in the protein viscose filament rayon refining, belong to textile industry viscose filament yarn production field.
Background technology
Azelon is with animal and plant albumen and fibrous raw material blend or graft copolymerization, again through after a kind of complex fiber material of making of processed.Animal protein commonly used has: milk protein, pupa albumen, vegetable protein have soybean protein, peanut protein, zein etc., and fibrous raw material has polyvinyl alcohol, polyacrylonitrile and regenerated cellulose etc.Protein in the azelon contains several amino acids, and azelon has the skin-protection and health-care effect, suits to make underwear, and is comfortable and easy to wear, liked by the consumer.
The azelon utilization of resources is extensive; The production good spinnability; The azelon product of processing have good hygroscopicity, gas permeability, soft, gloss is soft, the clothes made from protein fiber fabric have the unique function that profit flesh is supported skin, anti-inflammation, market prospects are wide.
Present azelon production method behind the pupa albumen long filament process acid bath spinning moulding, contains a large amount of acid and sulfide etc. on the strand; In order to remove acid and sulfide on the long filament etc., usually to carry out the desulfurization of alkaline soup refining processing, and contain a large amount of carboxyls on the pupa albumen viscose filament yarn; Can in alkaline solution, dissolve, after process alkali lye compresses and washes the desulfurization erect-position like this, will have part pupa albumen in heat alkali liquid, to dissolve on the fiber and come off; Cause product strength low, be prone to dry linting, shortcoming such as it is inhomogeneous to dye; And the albumen that comes off has increased environmental pollution, thereby has increased the pressure and the production cost of environmental protection treatment with compressing and washing liquid entering environmental protection treatment pond.Therefore, grope to improve necessary to the post processing refining process of pupa silk.
Summary of the invention
The present invention is intended to solve alkali cleaning step of compressing and washing in the flow process of the prior art comes off the protein dissolution on the azelon; Cause low, the easy dry linting of product strength; Inhomogeneous and problem of environment pollution caused dyes; A kind of technology of compressing and washing of azelon is provided, can either effectively carries out compressing and washing of azelon viscose filament yarn, make that again final product intensity is high, be difficult for dry linting, even dyeing and free from environmental pollution.
In order to realize the foregoing invention purpose, its concrete technical scheme is:
A kind of technology of compressing and washing that is applicable in the protein viscose filament rayon refining is characterized in that: comprise following processing step:
A, washing: the protein viscose filament rayon spinning cake is carried out the overflow washing;
A, use temperature are that 48～55 ℃ soft water is washed spinning cake, and wash time is 13～16 minutes, and the volume ratio of soft water and spinning cake is 1:2～3;
B, to use temperature be that 48～55 ℃ soft water is washed spinning cake, and wash time is 13～16 minutes, soft water and spinning cake volume ratio be 1:2～3;
C, use temperature are that 52～60 ℃ EDTA soft water solution is washed spinning cake, and wash time is 13～16 minutes, and the volume ratio of EDTA soft water solution and spinning cake is 1:2～3, and the concentration of said EDTA soft water solution is 0.14～0.16g/L;
B, desulfurization washing: the spinning cake after the completing steps A washing is carried out desulfurization overflow washing;
A, with temperature be 56～64 ℃ soft water to regulate the pH value be 11.5～12, then spinning cake is washed, wash time is 14～18 minutes, soft water and spinning cake volume ratio be 1:2～3;
B, to use temperature be that 57～65 ℃ soft water is washed spinning cake, and wash time is 14～18 minutes, soft water and spinning cake volume ratio be 1:2～3;
C, to use temperature be that 55～63 ℃ soft water is washed spinning cake, and wash time is 14～18 minutes, soft water and spinning cake bath raio be 1:2～3;
C, bleaching, wash, oil and dry: will pass through spinning cake after washing and the desulfurization washing and carry out conventional bleaching, wash, oil and baking operation obtains protein viscose filament rayon.
Soft water described in a of step B is to be that 29～33% sodium hydroxide solution is regulated the pH value through adding the NaOH percentage by weight.
The index of said soft water: my company to the detection index request of soft water is: basicity≤5.0mmol/L, hardness≤0.5mmol/L, iron≤0.05mg/L, Cl
-≤5.0mg/L, pH value: 6.5～8.5.
The useful technique effect that the present invention brings:
The problem that the present invention is directed to original technology has been made optimization and adjustment, has reached following effect:
1, the protein viscose filament rayon spinning cake compresses and washes in the process concise; Original technology is carried out independent caustic wash desulfuration work to it; And the present invention has cancelled the process of caustic wash desulfuration; Only plus-minus carries out desulfurization in water-washing process, when so just having avoided the high-concentration alkali liquor washing spinning cake in the alkaline cleaning procedure, causes albumen to come off and spinning cake look flower phenomenon;
2, accomplish in alkaline cleaning procedure because of the desulfurization of original technology; According to the optimization to original technology of the present invention; Compress and wash routine washing washing procedure and the washing step that plays desulfidation now in the process, all, its technology is improved through repeatedly research and experimental effort; Can accomplish desulfurization, can guarantee that again the quality of final product is not destroyed;
3, it is short that this process of employing is compressed and washed the pupa protein cellulose viscose production procedure of producing; Having solved original technology alkali cleaning dissolves the albumen on the fiber in alkaline solution; Cause environmental pollution problems, reduce discharge of wastewater, alleviated and reduced the pressure of company's environmental protection treatment and the problem of production cost; Solved because of the albumen low problem with the look flower of protein content that comes off, final product intensity is high, color and luster is even.
