Embodiment 1

[0043] refer to figure 1 , an ultra-coarse denier viscose filament aging process, belonging to the technical field of viscose filament spinning technology, the specific steps are as follows:

[0044] a. get ready the viscose glue I that required maturing degree in the viscose filament ripening process of ultra-coarse denier is 9-11, stand-by;

[0045] b. Continue aging and filtering the viscose I obtained in step a to obtain viscose II with a maturity of 8.5-10.5;

[0046] c. Continue aging and filtering the viscose II obtained in step b to obtain viscose III with a maturity of 7.5-9.5;

[0047] d. Continue aging and filtering the viscose III obtained in step c to obtain viscose IV with a maturity of 7.0-8.5;

[0048] e. Continue aging and filtering the viscose IV obtained in step d to obtain viscose V with a maturity of 6.0-8.0;

[0049] f. Continue aging and filtering the viscose V obtained in step e to obtain viscose VI with a maturity of 5.0-7.0, and send it to the next...

Embodiment 2

[0052] refer to figure 2 , an ultra-coarse denier viscose filament aging process, belonging to the technical field of viscose filament spinning technology, the specific steps are as follows:

[0053] a. get ready the viscose glue I that the degree of maturation required in the supercoarse denier viscose filament ripening process is 9-11, stand-by;

[0054]b. The viscose I obtained in step a is transported to the filter I1 to filter and continue to mature so that the degree of maturity is reduced to 8.5-10.5 to obtain viscose II;

[0055] c. transport the viscose II in step b to the buffer barrel I2, buffer and continue to mature the viscose, so that the degree of maturity reaches 7.5-9.5, and obtain the viscose III;

[0056] d. Conveying the viscose III in step c to the filter II3, so that the viscose III continues to mature in the filter II3, and the degree of maturity is reduced to 7.0-8.5 to obtain the viscose IV;

[0057] e. transport the viscose IV in step d to the buf...

Embodiment approach

[0070] refer to image 3 , an ultra-coarse denier viscose filament maturation process, belonging to the technical field of viscose filament spinning technology, is another preferred embodiment, and the specific steps are as follows:

[0071] a. get ready the viscose glue I that required maturing degree in the viscose filament ripening process of ultra-coarse denier is 9-11, stand-by;

[0072] b. continue to ripen the viscose I obtained in step a through a pipeline, and filter through a pipeline filter 6 to obtain viscose II with a degree of maturity of 8.5-10.5;

[0073] c. continue to mature the viscose II obtained in step b through the pipeline, and filter through the pipeline filter 6 to obtain the viscose III with a maturity of 7.5-9.5;

[0074] d. continue to ripen the viscose III obtained in step c through a pipeline, and filter through a pipeline filter 6 to obtain viscose IV with a maturity of 7.0-8.5;

[0075] e. continue to mature the viscose IV obtained in step d ...

Abstract

The invention discloses a super-coarse denier viscose filament aging process, which belongs to the technical field of viscose filament spinning technology. Viscose I of 11-> age and filter to get 8.5-10.5 viscose II-> age and filter to get 7.5-9.5 viscose III-> age and filter to get 7.0-8.5 viscose IV-> age and filter to get 6.0-8.0 Viscose V-> aging and filtering to obtain viscose VI-> of 5.0-7.0 to the next process, which solves the problem of milky white threads and serious color degradation of finished products in the production process of ultra-coarse denier viscose filaments in the prior art Problems that do not meet the acceptance criteria.

Description

technical field [0001] The invention belongs to the technical field of viscose filament spinning technology, and in particular relates to a super-coarse denier viscose filament aging process. Background technique [0002] The maturation process of ultra-coarse denier viscose filaments in the prior art is as follows: prepare the stock solution (prepared viscose, the degree of maturity is 9-11) -> intermediate barrel (buffer barrel, the viscose continues to mature in the intermediate barrel, so that the degree of maturity Reduced to process requirements 5-7, including stirring system) -> machine (spinning). The viscose produced by the existing technology often fails to meet the market demand. Take Yafite among the ultra-coarse denier viscose filaments as an example. Yafite, a flat cellulose fiber filament, is commonly known as Japanese grass, Raffia has the characteristics of strong air permeability, good moisture absorption, high flexibility, good dyeing performance, b...
