Problems solved by technology

With the increase of color masterbatch or colorant, such as the addition of carbon black, wire breakage will easily occur and the workmanship will deteriorate. Color masterbatch can improve workmanship, but the blackness L value cannot be further reduced
The required deep black color rendering effect is not easy to achieve

preparation example Construction

[0030] A kind of preparation method of dark black chrysanthemum petal nylon fiber with stock solution, according to the following steps:

[0031] The first step, the PE composite material of carbon-based colorant: polyethylene PE with 60% addition amount and 40% carbon-based colorant are blended and extruded to obtain PE composite material, wherein the carbon-based colorant is Vantablack carbon nanotube: carbon black =1:9, obtained by homogeneous blending, and the PE composite material of PE-coated carbon-based colorant was prepared by twin-screw blending. Such as figure 2 As shown in the schematic diagram of the homogeneous distribution of the colorant in PE, the colorant of the present invention is uniformly dispersed.

[0032] In the second step, the above-mentioned PE composite material is 30% by mass, the solubilizer maleic anhydride melt-grafted ethylene (PE-g-MAH) 5%, and PA6 65% are melt-blended, extruded and granulated to obtain a high concentration of nylon Black ...

Embodiment 2

[0038] It is similar to Example 1, except that the addition of nylon masterbatch is 7%, the addition of PA6 is 63%, and the sea component material is PET30%, the same blackness, the addition of colorant is less. See Table 2:

Abstract

The invention relates to a preparation method and a product thereof of a stock solution colored dark black ultrafine chinlon fiber. The preparation method of the stock solution colored dark black ultrafine chinlon fiber comprises the following steps: preparation of a PE composite material for a carbon-based colorant: blending and extruding 40-60 percent by weight of PE and 60-40 percent by weightof carbon-based colorant to obtain the PE composite material; melting and blending 8-30 percent of PE composite material, 2-5 percent of solubilizer maleic anhydride melt grafted ethylene (PE-g-MAH) and 65-90 percent of PA6, and extruding and granulating to obtain chinlon color masterbatches, so that the carbon-based colorant forms discontinuous fine capsules in the masterbatches; preparation of the ultrafine chinlon fiber. After being opened, the stock solution colored dark black polyester / chinlon daisy ultrafine fiber obtained by the utilization of the preparation method provided by the invention has a black chrominance L of less than or equal to 14, a color fastness to rubbing of greater than or equal to grade 4, a color fastness to washing of greater than or equal to grade 4, a color fastness to sunlight of greater than or equal to grade 4 and a splicing and mutual dyeing degree of greater than or equal to grade 4, and is controllable in cost, thereby having a higher market value.

Description

technical field [0001] The invention relates to a method for preparing dark black superfine polyamide fibers dyed with stock solution and a product thereof, belonging to the technical field of printing and dyeing. Background technique [0002] According to the survey of "FIBER ORGANON": from 2010 to 2015, the global production of superfine fiber leather maintained a compound annual growth rate of 9.6%, of which the global production of superfine fiber leather in 2015 was 165 million m 2 , it is estimated that the global output of microfiber leather will exceed 200 million m in 2020 2 Reached 240 million m 2 . At present, the annual output of sea-island fiber in my country exceeds 200,000 tons. As the fourth generation of synthetic leather, sea-island microfiber leather has been vigorously developed in China, and the output has increased from less than 40 million m ten years ago. 2 , with an annual output of 120 million m by 2017 2 . [0003] Microfiber has become a hot ...
