Description
Technical Field
The invention relates to the field of dyeing of ultra-high modulus polyethylene fibers, in particular to a dyeing method of ultra-high modulus polyethylene fibers and a product thereof.
Background
Ultra-high molecular weight polyethylene (UHMWPE), is polyethylene having a relative molecular weight of more than 150 ten thousand. The ultra-high modulus polyethylene has excellent functions such as abrasion resistance, excellent mechanical properties, corrosion resistance, no water absorption and excellent impact resistance. However, due to the easy crystallization orientation, the symmetrical structure and the inactive group of the molecular structure of the UHMWPE, the UHMWPE has extremely high surface inertia, extremely low surface energy and low chemical activity, so that the ultrahigh molecular weight polyethylene cannot be effectively dyed according to the traditional dyeing and finishing process.
There are generally several main types of methods for improving the dyeability of UHMWPE:
modifying the surface of UHMWPE (ultrahigh molecular weight polyethylene) to increase polar groups on the surface (for example, in the patent technology with the publication number of CN103074786A, the surface of a fiber is modified by adopting a method of a strong oxidant, the strong oxidant is a substance with strong oxidizing property such as sulfuric acid, nitric acid, potassium permanganate, and the like, and after treatment by an oxidant, a certain number of polar groups such as hydroxyl and carboxyl are formed on the surface of the fiber, so that dye molecules have certain affinity to the fiber, and the dye uptake and fastness are improved);
directly dyeing UHMWPE fibers by a conventional dyeing method;
dyeing is realized by a stock solution dyeing method of UHMWPE fibers or a method for preparing color master batches for melt spinning (for example, the patent technology with the application number of CN200810014184.1, the manufacturing method comprises the following steps of (1) swelling and dissolving raw materials to prepare spinning stock solution, (2) preparing jelly silk, (3) extracting the jelly silk, (4) spinning and drying, and (5) post-drafting and winding to prepare colored high-strength polyethylene fibers).
The surface modification method has the disadvantages of damaging the mechanical property of UHMWPE, complex process and high equipment cost. Although the conventional dyeing method is convenient in process, the UHMWPE has poor heat resistance and has poor dyeing effect due to no polar group on the surface. The stock solution dyeing or the melt spinning method dyeing by preparing the color master batch has good dyeing effect, but the micromolecule dye and fiber molecules are easy to migrate to the surface of the fiber when flowing through a spinning opening due to low fastness of combination.

The heating and curing time is 15-25 min.
The dye and the isocyanate curing agent in the invention can adopt commercial products.
Example 1
A dyeing method of ultra-high modulus polyethylene fiber adopts a chemical bonding method, and comprises the following specific steps:
(1) 100 g of waterborne hydroxyl acrylate resin emulsion (the hydroxyl content is 3.3wt percent, and the solid content is 42wt percent) containing 5 g of hexadecyl acrylate, 0.1 g of reactive brilliant blue KN-R type reactive dye and 25 g of Bayer 2655 isocyanate curing agent are added into a reaction bottle, stirred at high speed of 700rpm for 10 minutes to form dyeing glue solution, and then added into a glue tank of a gluing machine;
(2) after the ultra-high modulus polyethylene fiber or the product thereof is subjected to gum dipping and squeezing by a gluing machine, the ultra-high modulus polyethylene fiber or the product thereof is heated to 80 ℃ and cured for 20 minutes, and then the coloring of the ultra-high modulus polyethylene fiber or the product thereof is completed.
The color of the dyed fiber is blue. The tensile breaking strength of 200 undyed ultrahigh-modulus polyethylene fibers is 44.5N, the tensile breaking strength after dyeing is 52.0N, the dry rubbing fastness is 4-5 grade, the wet rubbing fastness is 5 grade, and the water fastness is 4-5 grade. Example 1 the thermogravimetric curves of the dyed ultrahigh modulus polyethylene fiber and as-received (undyed ultrahigh modulus polyethylene fiber) are shown in figure 2. Example 1 the initial thermal decomposition temperature of the sample and the virgin sample were 250 c and both maintained consistent thermal stability until 300 c, indicating that the dyeing method of the present invention did not thermally damage the ultra-high modulus polyethylene fiber itself.
Comparative example 1
(1) Adding 100 g of water-based hydroxyl acrylate resin emulsion (the hydroxyl content is 1.8wt percent, and the solid content is 42wt percent) containing 5 g of octadecyl acrylate, 0.1 g of active black KN-B type dye and 25 g of cyante company cymel325 amino resin curing agent into a reaction bottle, stirring at a high speed of 700rpm for 10 minutes to form glue solution, and adding the glue solution into a glue tank of a gluing machine;
(2) after the ultra-high modulus polyethylene fiber or the product thereof is subjected to gum dipping and gum extrusion by a gluing machine, the ultra-high modulus polyethylene fiber or the product thereof is heated to 130 ℃ and cured for 30 minutes, and then the coloring of the ultra-high modulus polyethylene fiber or the product thereof is completed.
The color of the dyed fiber is black. The tensile breaking strength of 200 undyed ultrahigh-modulus polyethylene fibers is 44.5N, the tensile breaking strength after dyeing is 52.0N, the dry rubbing fastness is 4-5 grade, the wet rubbing fastness is 5 grade, and the water fastness is 4-5 grade. Comparative example 1 the thermogravimetric curves of the dyed ultrahigh modulus polyethylene fiber and as-is (undyed ultrahigh modulus polyethylene fiber) are shown in figure 3. The initial thermal decomposition temperature of the comparative example 1 sample was 175 ℃, which is much lower than the initial thermal decomposition temperature of the as-received and example 1 samples, and the comparative example 1 sample could only maintain thermal stability consistent with the high modulus polyethylene fiber as-received until 175 ℃.
As can be seen from the comparison between example 1 and comparative example 1, which uses different curing agents and is cured by heating at a higher temperature suitable for the curing agents, achieves mechanical properties and coloring effects equivalent to those of example 1, but causes great thermal damage to the ultra-high modulus polyethylene fibers themselves.
Furthermore, it should be understood that various changes and modifications can be made by one skilled in the art after reading the above description of the present invention, and equivalents also fall within the scope of the invention as defined by the appended claims.
