Abstract
The invention provides a CC cellulose filament producing method by semicontinuous spinning. The producing method includes processing CC cellulose into an adhesive through a solvent under a condition not higher than -15 DEG C, performing filament injection through an R535 semicontinuous spinning machine, solidifying, stretching, and washing with water to obtain filaments. The producing method can replace methods of preparing the filaments from cellulose sulfonate, and eliminates pollution of hydrogen sulfide and carbon disulfide in a production process to the environment. The technical process is largely shortened. R535 traditional production equipment at present can be fully utilized for production.
Description
Technical field
The present invention relates to a kind of fiber product, specifically a kind of semicontinuous method of producing CC cellulosic filaments of spinning.
Background technology
At chemical fibre production field, viscose filament yarn is produced and has been applied for many years, viscose filament yarn has become traditional product, but in traditional long filament production technology, cotton linter is processed as to viscose glue, the major auxiliary burden of its lytic agent adopts poisonous and hazardous carbon disulfide always, this carbon disulfide exists in the use in transport, storage and production process and is absolutely unsafe, the accessory substance of meeting generating portion sulfide after use, directly cause environmental pollution, meanwhile, in the use, also there is the high problem that directly affects economic benefit of production cost.
Summary of the invention
The object of the present invention is to provide a kind of CC cellulose to produce the method for long filament, in viscose filament yarn production process, do not use carbon disulfide as solvent, and utilize existing viscose filament yarn production equipment R535A type spinning machine to produce.There is pollution-free material discharge, and can make full use of the feature that existing equipment is produced.
For achieving the above object, the technical scheme adopting is as follows in the present invention:
Step 1, selective polymerization degree become cellulose carbamate in 200～900 Cotton Pulp and the preparation of aqueous solution of urea hybrid reaction: CC cellulose, and ratio is: 1:4;
Step 2, by CC cellulose through being chilled in≤condition of-15 DEG C under, by the molten viscose glue that is made as of solvent, solvent is: the intermixture of clear water and alkali, wherein alkali accounts for 7～8% of clear water;
Step 3, the viscose glue body that dissolving is made adopt nylon leaching net to leach impurity;
Step 4, the viscose glue body after filtering is adopted quiet de-or connect de-tank quiet de-bubbled under vacuum negative pressure condition, the quiet de-time is 24 hours,
Step 5, the viscose glue body of sloughing bubble is transported to the semicontinuous R535 of spinning type spinning machine by pipeline, sprays silk be processed into fibre bundle by measuring pump, carry out acid bath simultaneously solidify by flow process, setting temperature is controlled at 10～50 DEG C;
Step 6, the fibre bundle after solidifying is stretched as to the fiber number of technological design by drawing-off dish;
Step 7, the fibre bundle after drawing-off is washed to disacidify by washing roller;
Step 8, by washing after fibre bundle in centrifugal cylinder, become spinning cake, spinning cake is made for continuous yarn product by post processing.
In technique scheme: in step 2, CC cellulose accounts for 5～10% of solution.
Nylon leaching net mesh in step 3 is 300 orders.
The spray silk speed of making the measuring pump in long filament step 5 is 0.5～2 times of sheave speed that postorder stretches.
Its body lotion component of acid bath of making in long filament step 5 is: sulfuric acid 5～20%, sodium sulphate 10～30%, all the other are clear water.
Good effect of the present invention is as follows: due in the production process of viscose glue, adopt Cotton Pulp and urea hybrid reaction have been made to the such scientific technology of cellulose carbamate CC cellulose, the viscose glue of producing can not produce any polluter in whole production process, adopt and avoid like this after the technique of carbon disulfide as solvent auxiliary material simultaneously, production cost will decline 10～20%, and postorder long filament operation can directly be utilized existing R535A spinning equipment, form thus a complete pollution-free and industrialized producing technology in batches cheaply, efficiently solve the pollution that uses carbon disulfide to exist as solvent auxiliary material in present viscose production large, high in cost of production exists for many years, insoluble problem, there is technological process simple, with short production cycle, the low significant advantage that waits of production cost.
