Embodiment 2

[0041] (1) Pretreatment process Pretreatment of ultra-high molecular weight polyethylene fibers. First, pre-shrink in the HT-S yarn steaming machine, the processing temperature is 110 ℃, and the processing time is 75 minutes. After pre-shrinking, the yarn is wound on the SSM precision winding machine, and the winding speed of the winding machine is 700 m / min, the tension is 0.8cN, and the overfeed rate is 2%.

[0042] 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.

[0043] 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.

[0044] (2) The dyeing process uses disperse dyes, among which, the addition amount of Disperse Golden E-3R (100% strength, Zhej...

Abstract

The invention discloses a method for preparing colored UHMW (ultra-high molecular weight) polyethylene fibers and belongs to the technical field of dyeing of textile materials. The method comprises the steps of presetting, spooling and dyeing. The dyeing process comprises the steps of preprocessing, dyeing and after treatment and particularly comprises the following steps: after preprocessing preset and spooled fibers, under the condition of existence of a leveling agent and a carrier with puffing and plasticizing effects, adding a disperse dye or an acid dye to carry out dyeing; rapidly draining dye liquor after finishing dyeing; and immediately injecting chilled with a temperature of minus 5 DEG C to 20 DEG C, processing for 5 to 10 minutes and then carrying out after treatment. The method for preparing the colored UHMW polyethylene fibers, which is disclosed by the invention, has the advantages of high dye-uptake, uniformity for dyeing, simple and convenient process and the like and can be applied to preparing the colored UHMW polyethylene fibers.

Description

technical field [0001] The invention relates to a method for preparing colored ultra-high molecular weight polyethylene fibers, 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 masterbat...
