Abstract
The invention discloses a cold-pad batch dyeing process of a bamboo pulp viscose fiber fabric. Tension generated in the production process is reduced by adopting volume cylinder treatment in the production process, and the bamboo pulp viscose fiber fabric is dyed by using the cold-pad batch dyeing process in the dyeing process. The fabric is even, transparent and full in color and luster of surface, and good in dyeing reproducibility and stability when the cold-pad batch dyeing process is adopted, the performance of good adsorbing and pouring breathability is fully reflected while the fabric has the excellent hand feeling by using a hydrophilic softener in the after treatment process, and the fabric is relatively comfortable to wear.
Description
Technical field
The present invention relates to technical field, particularly relate to a kind of cold rolling batch-dying process of bamboo pulp viscose fiber fabric.
Background technology
Bamboo pulp viscose fiber is to adopt chemical method that bamboo wood is made to bamboo pulp, and pulp is dissolved and makes bamboo pulp viscose solution, then makes by wet spinning.Lower, the large molecules align of bamboo pulp viscose fiber degree of crystallinity is more sparse, and regain is high, belongs to the regenerated celulose fibre similar to common viscose fiber.Because of its special cellulosic molecule structure, make fiber cross section abnormity be covered with oval space, its hygroscopicity, gas permeability etc. are considerably beyond cotton fiber.Bamboo pulp viscose fiber has good spinnability, fiber moisture absorption good permeability, soft, fabric fall good, dyeability is good, the soft feature such as bright of gloss.Bamboo pulp viscose fiber weaving face fabric has light, the refrigerant frankness of quality, and has the health care such as uvioresistant, mildew-resistant.
But the wet brute force of existing bamboo pulp viscose fiber is low, modulus is little, in the time of hygrometric state, have the weakness such as yielding, conformality is poor, the fabrics cloth cover color and luster that existing dyeing is made is not all even full, and reproducibility is poor, stability is bad, need to add a large amount of salt, permeability is bad, and degree of fixation is low, and can produce a large amount of waste liquids, in existing technique, conventionally adopt caustic soda/waterglass mixing alkaline agent, can greatly affect the feel of fabric, make fabric soft not.
Summary of the invention
Object of the present invention is exactly the cold rolling batch-dying process that a kind of bamboo pulp viscose fiber fabric is provided for the defect of above-mentioned existence.Pre-treatment adopts volume cylinder to process the tension force reducing in production process in process of production, when dyeing, with cold rolling batch-dying process, bamboo pulp viscose fiber fabric is dyeed.Select REACTIVE DYES consistent when synchronous by the screening of dyestuff: reactive orange SNE, reactive black SNE, reactive scarlet SNE, improves stability and the reappearance of dyeing.Cold rolling batch-dying process makes fabrics cloth cover color and luster even, saturating, full, reproducibility and good stability.Cold-rolling heap staining adopts room temperature fixation, without adding a large amount of salt, and good penetrability, degree of fixation is high, and waste liquid discharge capacity is few, energy-saving and cost-reducing.When cold-rolling heap staining, use fixation alkali to replace caustic soda/waterglass mixing alkaline agent, solved the problem that affect fabric feeling adding of waterglass, make the feel of fabric more soft, and the time shorten to 12 hour of banking up is raised the efficiency.After the performance that it is good that fabric moisture falls green permeability is fully demonstrated in using in haveing suffered journey hydrophilic softener to give the excellent feel of fabric, wear more comfortable.
The cold rolling batch-dying process technical scheme of a kind of bamboo pulp viscose fiber fabric of the present invention is,
Comprise pretreatment procedure, dyeing process and rear whole operation, wherein, pretreatment procedure adopts volume cylinder to process the tension force reducing in production process, rear whole operation is fully demonstrated the performance that it is good that fabric moisture falls green permeability when using hydrophilic softener to give the excellent feel of fabric, wears more comfortable; Dyeing process comprises following technological process:
(1) prepare dyestuff, alkaline agent;
(2) alkaline agent dyestuff mixes;
(3) roll material (soaks rolls, pick-up 65%);
(4) twine cloth, bank up;
(5) washing;
(6) soap;
(7) dry.
Pretreatment procedure is specially,
Destarch: scouring enzyme 2000L(Novozymes Company produces) 5g/l; Penetrant t A-1 (Binzhou morning twilight Chemical Co., Ltd.) 1g/l; Destarch temperature 70 C-75 DEG C, 10 roads; Hot water wash: wash 6 roads for 90 DEG C-95 DEG C;
Oxygen floats: the upper sea green cyclisation work of refining agent DKB-321(Co., Ltd) 8.0g/l; Soda ash 5.0g/l; Hydrogen peroxide 5.0g/l; Stabilizing agent P 8.0g/l; Penetrant t A-1 1.0g/l; Temperature: 90 DEG C-95 DEG C, 8 roads; Hot water wash: 100-95 DEG C of hot water wash 10 roads.
In step (1), dyestuff is reactive orange SNE, reactive black SNE, active blue SNE, reactive scarlet SNE, active yellow SNE.
Above-mentioned reactive orange SNE, reactive black SNE, active blue SNE, reactive scarlet SNE, active yellow SNE is reactive dyes with double active group, processes, power part 200%, Wuxi Runxin Dye Co., Ltd produces.
In step (1), alkaline agent is fixation alkali JL-210(Tianjin Jin Lu textile technology Co., Ltd).
In step (2), the consumption of fixation alkali should be 40-50g/L.The ratio of alkaline agent and dyestuff is 1:4, and the error in a hour of working is no more than 2%.
In step (3), pad in dye liquor process, pad mode: one soaks one rolls, pick-up 65%, pick-up is also liquid carrying rate, be on fabric with liquid weight and the percentage of the weight of fabric own.Saying is after solution on dye liquor tank band accurately, through roll roll on cloth cover later with solution weight and pad the percentage of front original fabric weight.
In step (4), the time of banking up is 12 hours, and while banking up, rotating speed is 8-10r/min, keeps environment temperature 20-40 DEG C while banking up.
Rear whole operation is used softener MT-90 or softener HF-103(Mitugao New Material Group) 40g/L; PH value 5-6.
When rear arrangement, select hydrophilic softener to arrange.Because bamboo pulp viscose fiber fabric has good moisture absorption, wet transmitting performance, softener selects improper meeting to bring negative effect to fiber hygroscopicity.
Beneficial effect of the present invention is:
1, bamboo pulp viscose fiber cold-rolling heap staining, cloth cover color and luster is full, and COLOR FASTNESS is good, and strength loss is little, can reduce energy consumption, cost-saving.
2, replace caustic soda/waterglass mixture to make alkaline agent with fixation alkali, improved bamboo pulp viscose fiber fabric feeling, active material improves in the stability of alkaline bath.
3, add hydrophilic softener, not only give the feel of bamboo pulp viscose fiber fabric excellence, and the performance of bamboo pulp viscose fiber fabric moisture is fully demonstrated.Fabric moisture absorption is ventilative, refrigerant frankness.
detailed description of the invention:
In order to understand better the present invention, describe technical scheme of the present invention in detail with instantiation below, but the present invention is not limited thereto.

Technological process
Prepare dyestuff, alkaline agent → alkaline agent dyestuff and mix → roll material (soaks rolls, pick-up 65%) → twine cloth, bank up → wash → soap → dry
The selection of dyestuff
Cold-rolling heap staining requires REACTIVE DYES solubility high, and when direct little and colorant match, the substantivity of dyestuff is basically identical, otherwise can affect the stability of cold-rolling heap staining.Whether the substantivity of REACTIVE DYES is consistent, can pass through the Rf value R of dyestuff
fjudge.
R
fmethod of testing dyestuff is at room temperature made into certain density solution, get in the beaker of 100ml as for unified standard, one end of Medium speed filter paper is dipped vertically into dye liquor 1cm, after 30min, take out, and dry in cool place place, measure the height h2 of the high h1 of water and dyestuff rising
Rf=h2/h1
The Rf value Rf of part REACTIVE DYES is in table 1
