Problems solved by technology

[0003] However, most of the traditional acrylic fabrics are dyed through re-dyeing process. Although they can be dyed with disperse dyes, they usually need to be dyed under the conditions of high temperature and high pressure or the presence of carriers, which will cause great damage to the fibers and poor dyeing performance. The uniformity of dyeing is poor, so that the color fastness of the final acrylic fabric is poor (such as washing fastness and light fastness); The cost is also higher
Therefore, in order to solve the above problems, both the low temperature dyeing technology can be realized and the damage to the dyed products can be alleviated by the traditional dyeing process, and the hand feeling of the fabric (fabric) can be improved. Improve the dyeing rate of dyes on acrylic fibers, but it does not solve the existing problems as a whole

Embodiment 1

[0045] A kind of high color fastness spinning acrylic fiber fabric, described acrylic fiber fabric is mainly formed by weaving of acrylic fiber yarn, and its specific preparation method is:

[0046] A, select polyacrylonitrile, colorant, dispersant, toner, stabilizer, flame retardant, antioxidant and accelerator according to the weight ratio of each raw material in the embodiment 1 of table 1, after mixing evenly then, pass The feeding port of the screw extruder is added to the extruder, and the extrusion temperature of each section of the extruder is set to 120°C, 140°C, 180°C, 220°C, and 190°C, so that the mixture becomes a melt, and then passes through the screw Extrude, extrude and granulate to make the corresponding color masterbatch;

[0047] B. Processing and spinning the above-mentioned color masterbatch through a spinning machine, the spinning temperature is set at 175°C to 185°C, and the synthetic fibers obtained after spinning are deformed to form acrylic yarns; the...

Embodiment 2-10

[0050] A kind of high color fastness spun acrylic fiber fabric, described acrylic fiber fabric is mainly formed by weaving of acrylic fiber yarn, the specific preparation method is consistent with the method described in embodiment 1, the difference is that wherein the weight ratio of raw materials used is according to the table 1 and the concrete weight ratio of embodiment 2-10 corresponding embodiment in table 2 is selected.

[0051] The acrylic fabrics prepared in the above examples were randomly selected, and their color fastness was detected and analyzed according to national standards.

[0052] Select the acrylic fabric obtained in Example 1 to detect and analyze, and the analysis results are: its color fastness to washing reaches 4 to 5 grades, the color fastness to perspiration reaches 4 to 5 grades, and the color fastness to light and sunlight reaches 8 grades;

[0053] The acrylic fabric obtained in Example 3 is selected for detection and analysis, and the analysis r...

Abstract

The invention relates to a high-colour fastness spinning acrylic fabric, which belongs to the technical field of a textile material and application. In order to solve the problems of low dyeing rate, low colour fastness, easy decoloration and the like of the fabric in prior art, the invention provides the acrylic fabric which is mainly woven by acrylic yarn; the acrylic yarn is mainly prepared from the materials as follows in weight ratio: 70-80% of polyacrylonitrile, 5-12% of a colouring agent, 3-8% of a dispersing agent, 5-10% of a toner, 5-12% of a stabilizer and 2-8% of an accelerating agent. The acrylic fabric prepared from the acrylic yarn made from the materials has the advantages of being high in colour fastness, uniform in chromatic aberration and consistent in toner, and has excellent effects in such aspects as flame-retardant effect, anti-oxidation effect and the like.

Description

technical field [0001] The invention relates to a spun acrylic fabric, in particular to a spun acrylic fabric with high color fastness, which belongs to the technical field of textile materials and applications. Background technique [0002] Acrylic fiber is the trade name of polypropylene fiber in my country, and it is called "Olon" and "Cashmiron" abroad. It usually refers to the copolymer of more than 85% acrylonitrile and the second and third monomers. Synthetic fibers produced by spinning or dry spinning. Because acrylic fiber has the advantages of excellent softness, warmth, light resistance and radiation resistance, its appearance and performance are very similar to wool. It is called "artificial wool" and is an important wool textile material. Existing textile field usually is made into wool textile materials such as acrylic yarn, acrylic wool or acrylic wool, and then is woven into acrylic fabric. In actual production, acrylic fiber and wool are often spun to compl...
