Aiming at the defects of the prior art, the invention aims to provide the raw liquid coloring fabric which is soft in hand feeling and excellent in color fastness, and the invention also provides the processing technology of the raw liquid coloring fabric, so that the processing, boiling, dyeing and finishing modes are not needed in the dyeing and finishing process, the fiber damage is small, the process flow is short, the discharge of printing and dyeing wastewater is greatly reduced, and the current-stage green environmental protection development concept is met.
The dope dyed fabric adopts the following processing flow: singeing, desizing and tentering the dope dyed yarns to obtain dope dyed fabric;
wherein: the material liquid used in the desizing procedure is as follows: desizing enzyme OPT-280: 6-8 g/l, chelating agent: 1-5 g/l and penetrant: 6-8 g/l.
Preferably, the desizing enzyme is wide temperature type alphA amylase OPT-280, the chelating agent is phosphate chelating agent SQ-A, and the penetrating agent is polyethylene glycol ether type penetrating agent WA-M. The manufacturer of OPT-280 is Federal science-specific chemical Co., Ltd, the manufacturer of SQ-A is Ruri Fine chemical Co., Ltd, and the manufacturer of WA-M is Ruri Fine chemical Co., Ltd.
Desizing process conditions: the temperature of the steam box is 98-100 ℃, and the stacking time is 25-30 min.
Dope-dyed fibers, also known as spun-dyed fibers, are fibers made by adding suitable colorants during polymerization or during spinning in the production of chemical fibers. Dope dyeing the main consideration that such a fiber variety is incorporated into the "green fiber" family is from the point of view of the production process: because the dope dyed fiber endows various colors to the fiber in the production process, the printing and dyeing link is omitted in the downstream production process, the green degree of the prepared textile is greatly improved, and the dope dyed fiber has outstanding environment-friendly characteristics.
Singeing process conditions: vehicle speed: 100 to 120m/min, and a normal combustion pressure of 14 to 18 mbar.
The material liquid used in the tentering process is: the modified polysiloxane softening agent TF-4865C is blended with the polyethylene polyamine color fixing agent GD-80. The concentration of the modified polysiloxane softening agent is 10-30 g/l, and the concentration of the polyethylene polyamine color fixing agent is 5-15 g/l. The manufacturer of TF-4865C is Daizhijianggang GmbH, and the manufacturer of GD-80 is Federal science-specific chemical Co. By adopting the feed liquid, excellent color fastness of the fabric is ensured.
Tentering process conditions: vehicle speed: 60-80 m/min, overfeeding: 3% -3.5%, overfeeding: 0%, cropping overfeeding: -1.5% to-2.5%.
Compared with the prior art, the invention has the following advantages:
1) the production mode has continuity, and the continuous production of large goods can be realized.
2) The traditional pretreatment adopts a desizing-scouring process, a large amount of chemicals such as NaOH and the like are used in the processing process, the fiber is greatly damaged, the hand feeling of the processed fabric is poor, and the color of the fabric is seriously changed; the desizing process adopted by the invention uses the wide-temperature alpha amylase OPT-280, the reaction is mild in the treatment process, the damage to fibers is small, the treated fabric is soft in hand feeling, and the color of the fabric is almost unchanged.
3) The polyethylene polyamine color fixing agent is a cationic polymer, can be crosslinked with fibers at high temperature, can be crosslinked with reactive dyes in dye liquor, and forms a net structure on the fibers through the bidirectional crosslinking action with the fibers and the dyes, so that the fastness of the fabric is improved.
4) The invention greatly reduces the discharge of printing and dyeing wastewater by shortening the processing flow, and accords with the current environmental protection development concept.
5) The method selects the dope dyed yarn, does not need boiling and dyeing the fabric in the dyeing and finishing process, has short dyeing and finishing processing flow, saves the production cost, and is green, healthy and environment-friendly.
7) The fabric finished by the method disclosed by the invention has the following color fastness tests:
color fastness to washing: AATCC 61-20103A test method, the color change is more than 4 grade, and the staining is more than 4 grade;
acid perspiration fastness resistance: the AATCC 15-2009 test method has the advantages that the color change is more than 4 grades, and the staining is more than 4 grades;
