Abstract
The invention relates to an old clothes recovery method, which comprises the following steps of: using old cotton clothes as a raw material to prepare cotton pulp, processing by the use of caustic soda and carbon disulfide to obtain orange sodium cellulose xanthate, dissolving in a dilute sodium hydroxide solution to form viscous viscose glue, filtering and maturating viscose glue, standing at 38 DEG C for 20h, followed by deaeration, carrying out wet spinning, adding a solidification liquid which is composed of sulfuric acid, sodium sulphate and zinc sulfate, letting sodium cellulose xanthate in viscose glue react with sulfuric acid in the solidification liquid for decomposition, regenerating cellulose and precipitating, washing, desulphurizing, bleaching and drying cellulose fiber to form viscose fiber. By the utilization of the old clothes recovery method for preparation of viscose fiber, viscose fiber is woven into various mat products, thus changing waste into valuables. The technology provided by the invention is easy to operate and is convenient for popularization and utilization.
Description
Technical field
The present invention relates to a kind of friperie recoverying and utilizing method.
Background technology
Along with growth in the living standard, the clothes that is Protected from Cold of in the past just being used for dispeling cold has become the thing of the indispensability of modern's showing personality, decorative appearance, and the cloth of clothes is by being made into fiber miscellaneous.Fiber is a kind of tough and tensile and flexible material of tool.Fiber divides a variety of, and the natural chemical synthesis that has is arranged.Natural in cotton fiber, flax fibre, wool fibre or the like.And chemical fibre divides two kinds: a kind of is the fiber that on the natural fabric basis, reproduces, and is called artificial fibre or reprocessing fiber.Such as artificial cotton is exactly a kind of artificial fibre; This fiber also comes from natural animal and plant fiber in fact; Just they are " defect wares " in the natural fabric, and this fiber is shorter, have only half length of normal fiber; Can't directly be used for weaving cotton cloth, need through using again after the reprocessing.Modal in the artificial fibre is exactly viscose, and the artificial cotton that marks in some clothes compositions is exactly that viscose is processed.
Also having a kind of chemical fibre has been synthetic fiber fully just.Clothes such as polyester material are made with chemical synthetic fiber; The chemical composition of terylene is a polyester fiber; In a lot of plastic products, also use; This fibrid is made through chemical synthesis fully, through imitating the chemical molecular formula of various natural fabrics, thereby produces various chemical fibre products.
At present, utilize friperie to reclaim to process viscose to be used for various ground cushion products and still do not have report.
Summary of the invention
Technical problem to be solved: the object of the invention provides a kind ofly to be utilized friperie to reclaim to process the viscose method, to be made into the purposes of various ground cushion products with viscose.
Technical scheme: a kind of friperie recoverying and utilizing method is characterized in that: with old cotton clothes is raw material, processes the cotton pulp dregs of rice; Handle with caustic soda, carbon disulfide, obtain orange-yellow sodium cellulose xanthate, be dissolved in again in the diluted sodium hydroxide solution; Become the viscose glue of thickness, viscose glue is through filtration, maturation, at 38 degree held 20h; After the deaeration, carry out wet spinning, solidification liquid is made up of sulfuric acid, sodium sulphate and zinc sulfate; Sodium cellulose xanthate in the viscose glue and the effect of sulfuric acid in the solidification liquid and decompose, cellulose regenerated and separate out, the gained cellulose fibre becomes viscose after washing, desulfurization, bleaching, drying.
Beneficial effect: utilize friperie to reclaim to process the viscose method, be made into the purposes of various ground cushion products, turn waste into wealth with viscose.To becoming the useless processing of handling, be beneficial to environmental protection and resource regeneration, social environment and economic benefit are had positive effect.The inventive method science is feasible, and technological operation is easy, is easy to be extended and applied.
The specific embodiment
A kind of friperie recoverying and utilizing method is a raw material with old cotton clothes, processes the cotton pulp dregs of rice; Handle with caustic soda, carbon disulfide, obtain orange-yellow sodium cellulose xanthate, be dissolved in again in the diluted sodium hydroxide solution; Become the viscose glue of thickness, viscose glue is through filtration, maturation, at 38 degree held 20h; After the deaeration, carry out wet spinning, solidification liquid is made up of sulfuric acid, sodium sulphate and zinc sulfate; Sodium cellulose xanthate in the viscose glue and the effect of sulfuric acid in the solidification liquid and decompose, cellulose regenerated and separate out, the gained cellulose fibre becomes viscose after washing, desulfurization, bleaching, drying.
Viscose is artificial silk, ice silk, viscose filament yarn again.Have characteristics such as ventilative, antistatic, that dyeing is gorgeous.Viscose belongs to regenerated celulose fibre.It is to be raw material with the native cellulose, processes the soluble cellulose sulphonic acid ester through operations such as alkalization, aging, sulfonation, is dissolved in sig water again to process viscose glue, processes through wet spinning.Adopt different raw materials and spinning technique, can obtain common viscose fiber respectively, koplon and high tenacity staple fibre etc.Common viscose fiber has general physical mechanical performance and chemical property, divides cotton type, wool type and long filament type again, is commonly called as artificial cotton, artificial wool and artificial silk.Koplon has the higher degree of polymerization, brute force and wet modulus.High tenacity staple fibre has higher strength and fatigue performance.
