Embodiment 2

[0039] After winding, install the cage, hang it into the pretreatment tank, enter the fiber surface treatment process, and treat the fiber surface with 80% (mass percent) sulfuric acid for 30 minutes.

[0040] The treated acid liquid is poured into the acid recovery tank, and recycled after purification. Add soft water to the pretreatment tank, neutralize to neutral with 6g / L 30% (mass percentage) NaOH, and then wash with soft water again.

[0041] (2) Disperse dyes are used in the dyeing process. Among them, the addition amount of Disperse Golden E-3R (100% strength, Zhejiang Huadie Dyestuff Chemical Co., Ltd.) is 0.95% (o.w.f.), and Disperse Brilliant Blue 2BLN (100% strength is 100%, the manufacturer: Zhejiang Longsheng Dyestuff Co., Ltd.) the addition amount is 0.05% (o.w.f.), the addition amount of Disperse Bright Yellow 4GL (100% strength, Shaoxing Tianbao Chemical Dyestuff Co., Ltd.) is 2.15% (o.w.f.) , the amount of high-temperature leveling agent G-201 is 3.5% (o.w.f...

Embodiment 3

[0050] After winding, it is loaded into a cage, hoisted into the pretreatment tank, and enters the fiber surface treatment process. Treat the fiber surface with 50% (mass percent) nitric acid for 25 minutes.

[0051] The treated acid liquid is poured into the acid recovery tank, and recycled after purification. Add soft water to the pretreatment tank, neutralize it with 4g / L 30% (mass percentage) NaOH to neutral, and then wash it with soft water again after neutralization.

[0052] (2) The dyeing process uses disperse dyes. The dosage of disperse black KS (150% strength, Shanghai Jiepu Dyestuff Co., Ltd.) is 1.2% (o.w.f.), and disperse violet H-FRL (100% strength, Anhui Asia Bang Chemical Co., Ltd. (Changzhou No. 1 Branch) dosage is 5.5% (o.w.f.), disperse yellow brown S-4RL (strength is 100%, Hangzhou Fuyuan Textile Raw Materials Co., Ltd.) dosage is 0.2% (o.w.f.), high temperature The dosage of leveling agent G-201 is 4.5% (o.w.f.), and the dosage of dyeing agent G-202 is ...

Embodiment 4

[0058] After winding, it is loaded into a cage, hoisted into the pretreatment tank, and enters the fiber surface treatment process. Treat the fiber surface with 95% (mass percent) sulfuric acid for 8 minutes.

[0059] The treated acid liquid is poured into the acid recovery tank, and recycled after purification. Add soft water into the pretreatment tank, neutralize to neutral with 10g / L 30% (mass percentage) NaOH, and then wash with soft water twice.

[0060] (2) Acid dyes are used in the dyeing process, the dosage of Acid Ulite Red S-GN (100% strength, manufacturer: Qingdao Shuangtao Fine Chemical Co., Ltd.) is 5.3% (o.w.f.), Acid Ulite Yellow S The dosage of -2G (100% strength, manufacturer: Qingdao Shuangtao Fine Chemical Co., Ltd.) is 1.26% (o.w.f.), acid Ulite Blue 6B (350% strength, manufacturer: Qingdao Shuangtao Fine Chemical Co., Ltd. ) is 0.22% (o.w.f.), the acid leveling agent TBW-951 (Shaoxing Demei Chemical Co., Ltd.) is 3.5% (o.w.f.), and the dyeing agent G-202...

Abstract

The invention discloses an ultrahigh molecular weight polyethylene fiber dyeing method and belongs to the technical field of textile material dyeing. The ultrahigh molecular weight polyethylene fiber dyeing method comprises processes of pretreatment, dyeing and aftertreatment. The dyeing process comprises adding a disperse dye or an acid dye into pretreated fibers in the presence of a leveling agent and a carrier having effects of puffing and plastification, carrying out dyeing, fast discharging the dyeing solution immediately after dyeing, pouring chilled water having a temperature of -5 to 20 DEG C into the dyed fibers, carrying out treatment for 5 to 10min, and carrying out aftertreatment. The ultrahigh molecular weight polyethylene fiber dyeing method has the advantages of high dyeing rate, uniform dyeing effect and simple processes, and can be used for ultrahigh molecular weight polyethylene fiber preparation.

Description

technical field [0001] The invention relates to a dyeing and processing method of ultra-high molecular weight polyethylene fiber, which belongs to the technical field of dyeing of textile materials. Background technique [0002] Ultra-high molecular weight polyethylene fiber (UHMW PE), also known as high-strength and high-modulus polyethylene fiber, is widely used as a special fiber and high-performance fiber because of its excellent mechanical properties, stable chemical properties and ideal mechanical properties. Aerospace, military machinery, transportation, sports equipment and other fields. However, due to the relatively high molecular weight, the degree of orientation of polyethylene is also high, the molecular arrangement is regular, the crystallinity is high, and dyeing is more difficult. At present, there are mainly two conventional methods, one is the method of adding dye masterbatch, and the other is the method of modification. The method of adding color masterb...
