Abstract
The invention relates to a waste cotton textile regeneration spinning solution formulation and a wet spinning process. The waste cotton textile regeneration spinning solution formulation is characterized by comprising short fiber aggregates which are obtained by treating waste cotton textiles and a carboxymethyl chitosan water solution, wherein the short fiber aggregates are uniformly dispersed into the carboxymethyl chitosan water solution; the lengths of fiber main bodies of the short fiber aggregates are 0.2-1.2 cm; and the concentration of carboxymethyl chitosan in the carboxymethyl chitosan water solution is 10-30 g/l, furthermore, the mass ratio of carboxymethyl chitosan to cotton short fibers is 3:1-1:3, and the concentration of the cotton short fibers in the solution is not higher than 5-15 g/l. Compared with the prior art, cotton process filaments prepared by utilizing the waste cotton textile regeneration spinning solution formulation and the wet spinning process remain the characteristics of excellent moisture absorbing and ventilating performances, thermal insulation property and flexibility, belong to environment-friendly products, are uniform and are suitable for producing high-quality cotton clothes; and the production process is concise and strong in operability, and wastewater produced by a coagulating bath is pollution-free and can be directly discharged.
Description
Technical field
The present invention relates to the regeneration of waste and old cotton textiles, specifically refer to a kind of waste and old cotton textiles spinning solution prescription and wet spinning technology.
Background technology
At present, the regeneration on textile garment mainly is to extract viscose by traditional textile technology secondary operations and with its dissolving back to waste and old cotton textiles both at home and abroad.Weaving secondary operations gained yarn quality is low, be low-and-medium-grade products, and production cost is higher, and the utilization rate of fiber is low.And dissolving back spinning viscose has not only destroyed the premium properties of cotton fiber, also can produce a large amount of chemical wastewaters and contaminated environment in process of production
Summary of the invention
Technical problem to be solved by this invention is that the present situation at prior art provides premium properties and the eco-friendly waste and old cotton textiles regeneration spinning solution prescription that can guarantee cotton fiber after a kind of waste and old cotton textiles regeneration.
Another technical problem to be solved by this invention provides premium properties and the eco-friendly waste and old cotton textiles regeneration wet spinning technology that can guarantee cotton fiber after a kind of waste and old cotton textiles are regenerated.
The present invention solves the problems of the technologies described above the technical scheme that adopts: this waste and old cotton textiles regeneration spinning solution, it is characterized in that comprising staple fibre aggregate and the carboxymethyl chitosan sugar aqueous solution that obtains by after the waste and old cotton textiles processing, described staple fibre aggregate is dispersed in the carboxymethyl chitosan sugar aqueous solution;
Wherein, the modal staple length of described staple fibre aggregate is greater than 0.2cm～1.2cm; The concentration of cm-chitosan is 10～30g/l in the described carboxymethyl chitosan sugar aqueous solution, and the mass ratio of cm-chitosan and cotton short fiber is 3:1～1:3, and cotton short fiber concentration in spinning solution is 5g/l～15g/l.
Use the wet spinning technology of waste and old cotton textiles regeneration spinning solution as claimed in claim 1, it is characterized in that under pressure is the condition of 0.2MPa～5.0MPa, described regeneration spinning solution being extruded from the spinneret orifice of spinning machine, liquid stream polymerizing curable in coagulating bath becomes precursor, described precursor carries out the Pyatyi drawing-off by drawing rollers, and drafting multiple is respectively 1.1 times, 1.7 times, 2.2 times, 1.8 times, 1.5 times;
Wherein the aperture of spinneret orifice is 2mm～5mm, and it is the aqueous citric acid solution of 10～100g/l that concentration is adopted in described coagulating bath; Spacing of described drawing rollers is 1.5～2.0cm.
Compared with prior art, waste and old cotton textiles regeneration spinning solution prescription provided by the present invention and the prepared cotton technology long filament of wet spinning technology have kept the good moisture permeability of cotton fiber, the characteristics of warming softness, belong to the green environmental protection product, and cotton technology long filament bar is done evenly, is applicable to make high-quality cotton clothes; Concise production process, workable, the waste water that coagulating bath produces does not have contaminative to environment, can directly discharge.
Description of drawings
Fig. 1 is the process chart of the embodiment of the invention.

Describe in further detail below in conjunction with the present invention of accompanying drawing embodiment.
(1) at first prepare spinning solution:
Waste and old cotton textiles are processed into the staple fibre aggregate that modal staple length is 0.2～1.2cm, and putting into concentration is in the carboxymethyl chitosan sugar aqueous solution of 10～30g/l; The mass ratio of cm-chitosan and staple fibre aggregate is 3:1～1:3, and mechanical agitation to staple fibre aggregate evenly disperses, and makes the regeneration spinning solution.The concentration of regeneration spinning solution middle short fiber aggregate is 5g/l～15g/l.
(2) preparation of coagulating bath: adopting concentration is the aqueous citric acid solution of 10～100g/l.
(3) wet spinning: the regeneration spinning solution that under 0.2MPa～5.0MPa step (1) is obtained is extruded from the spinneret orifice of spinning machine, and liquid flows to that polymerizing curable becomes precursor in the coagulating bath in the step poly-(2).Wherein spinneret orifice diameter is 2mm～5mm.
(4) precursor hygrometric state drawing-off: the precursor that solidifies generation in coagulating bath carries out the Pyatyi drawing-off by drawing rollers, obtains cotton technology long filament.Above-mentioned Pyatyi drafting multiple is respectively 1.1 times, 1.7 times, 2.2 times, 1.8 times, 1.5 times, and roller draft spaces and is 1.5～2.0cm.
The cotton technology long filament for preparing is detected, and testing result is as shown in table 1.
Table 1
Final products of the present invention are a kind of cotton technology long filament, are a kind of novel regeneration cotton fibers, have characteristics such as sucting wet air permeability is good, warmth retention property is good, for the regeneration of waste and old cotton textiles provides a kind of application approach succinct, environmental protection.
