Problems solved by technology

Such disadvantages are: 1. The usual color masterbatch factory needs to be equipped with more than 3,000 kinds of color masterbatches, and one color masterbatch is equipped for each fiber color; 2. Each color masterbatch in the fiber factory cannot be completely Consumption, most medium-sized fiber factories have hundreds of idle color masterbatches, resulting in significant inventory management difficulties and waste
Moreover, traditional color masterbatches need to be pre-dried before use, which increases the factory process and causes energy loss

Embodiment 1

[0035] Embodiment 1 Preparation of yellow polyamide six monofilament fibers

[0036] Firstly, liquid color masterbatches of two basic colors, yellow and white, are produced respectively, and processed into yellow paste with a content of 35% and white paste with a content of 50%. The white pulp only plays a diluting role, so as to increase the amount of yellow pulp added to achieve stable metering. Processing of yellow and white basic colors: 35 parts of yellow dye and 65 parts of refined castor oil and polypropanol, or 50 parts of white pigment and 50 parts of dispersant refined castor oil and polypropanol, using a high-speed disperser Mix and disperse evenly, and use a horizontal grinder to disperse and control the particle size of dyes or pigments (less than 5 microns), and then adjust the viscosity of the liquid masterbatch to meet the smooth pumping of the automatic feeder.

[0037] Then, color matching: take 0.8 parts of traditional yellow masterbatch, which is usually u...

Embodiment 2

[0041] Embodiment 2 Preparation of orange-red polyester fiber

[0042] First of all, the liquid color masterbatches of red and yellow two basic colors are produced respectively, and processed into red and yellow pastes with a content of 40%. Processing of red and yellow basic colors: 40 parts of red and yellow dyes and 60 parts of dispersant refined castor oil and polypropylene alcohol are mixed and dispersed evenly with a high-speed disperser, and dispersed and dyed or pigmented by a horizontal grinder Particle size control (less than 5 microns), and then adjust the viscosity of the liquid masterbatch to meet the smooth pumping of the automatic feeder.

[0043] Then, take 2 parts of traditional red masterbatch, which is usually used to produce colored fibers with 2% addition. Using the data color matching method of CIE L*a*b, the following results are obtained: mixing red 1.28% and yellow 0.4% can completely replace the target color of the traditional red masterbatch with 2%...

Abstract

The invention discloses a liquid color masterbatch composition, a preparation method and an application thereof. The liquid color masterbatch composition is liquid color masterbatch of primitive color and comprises the following components in percentage by weight: dye or pigment 30-50% and dispersant in balance; and the dispersant comprises at least one of vegetable oil, mineral oil and liquid low polymer. The preparation method of the liquid color masterbatch composition has simple process; the prepared liquid color masterbatch composition can be colored on site and on-line added, and can reduce pre-drying step in production and simplify the production process of colored fibers; the liquid color masterbatch composition has high dispersion and low addition amount; a plurality of colors can be covered by little basic color masterbatch so as to reduce waste and production cost of colored fibers; and the liquid color masterbatch composition is suitable for fiber dyeing and on-line addition.

Description

technical field [0001] The invention relates to the field of fiber processing and dyeing, in particular to a liquid color masterbatch composition, a liquid functional color masterbatch composition, a preparation method and application thereof. Background technique [0002] In-fiber dyeing has become popular in recent years. Compared with external dyeing of yarn or fabric, the process of in-fiber dyeing has significant environmental protection and economic value in terms of waste water, gas and energy. [0003] At present, the general method of in-fiber coloring is: in the spinning chip or melt stage, dyeing with masterbatch to produce colored fibers. Such disadvantages are: 1. The usual color masterbatch factory needs to be equipped with more than 3,000 kinds of color masterbatches, and one color masterbatch is equipped for each fiber color; 2. Each color masterbatch in the fiber factory cannot be completely Consumption, most medium-sized fiber factories have hundreds of id...
