Abstract

The invention belongs to the field of brighteners, and particularly relates to a spinning brightener. The spinning brightener is composed of the following components in percentage by mass: 0.2%-0.5% of a fluorescent brightener, 40%-50% of sodium sulfate, 5%-15% of a surfactant, 4%-15% of a cosolvent, 3%-10% of a stabilizer and the balance of water, wherein the fluorescent brightener is composed of a cotton fluorescent brightener MST and a PS-1 polyester fluorescent brightener in a mass ratio of 1:(1-1.5). The spinning brightener has the beneficial effects of high washing fastness, good heat stability and good whitening effect, and the whiteness of the spinning brightener is less influenced by pH levels.

Description

A kind of weaving brightening agent

Technical field

The invention belongs to brightening agent field, be specifically related to a kind of weaving brightening agent.

Background technology

Brightening agent is the organic compound that a class can improve the whiteness such as fabric and paper, also known as Optical Bleaching Agent, fluorescent whitening agent.Fabrics etc. are usually yellow owing to containing foreign pigment, past all adopts the method for chemical bleaching to decolour, the method of brightening agent is added in present employing in goods, its effect is that the sightless ultraviolet radiation that goods absorb is transformed into indigo fluorescent radiation, become white with original gold-tinted radiation complementation, improve product whiteness in the sunlight.

The quality requirement of current textile printing and dyeing industry to used fluorescent whitening agent is more and more higher, and the fabric pure color light brightened is vivid not only to require fluorescent whitening agent to ensure, and fluorescence has higher whitening ability.Existing brightening agent has stronger whitening ability mostly, but ubiquity fastness to washing is poor, poor heat stability, and whiteness value is easily by the shortcoming that pH value affects.

Summary of the invention

The object of the invention is to overcome that brightening agent fastness to washing in prior art is poor, the technical deficiency of poor stability, the weaving brightening agent that a kind of fastness to washing is good, good stability, whitening effect are good is provided.

For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:

A kind of weaving brightening agent, be made up of the component of following mass percent: fluorescent whitening agent 0.2-0.5%, sodium sulphate 40-50%, surfactant 5-15%, cosolvent 4-15%, stabilizing agent 3-10%, all the other are water.

Further, described fluorescent whitening agent is cotton fluorescent whitening agent MST and PS-1 fluorescent Dacron whitening agent, and the mass ratio of described cotton fluorescent whitening agent MST and PS-1 fluorescent Dacron whitening agent is 1:1-1.5.

Further, the granularity size of described S-1 fluorescent Dacron whitening agent is for being less than 2 μm.

Further, described surfactant is nonionic surface active agent.

Further, the carbon atom number in described nonionic surface active agent carbochain is 10-18.

Further, caprolactam elected as by described cosolvent.

Further, described stabilizing agent is EDTA.

Further, a kind of weaving forms by the component of brightening agent by following mass percent: fluorescent whitening agent 0.3%, sodium sulphate 45%, surfactant 10%, cosolvent 10%, stabilizing agent 6%, all the other are water.

The intermixture of cotton fluorescent whitening agent MST and PS-1 fluorescent Dacron whitening agent is adopted as the object of brightening agent to be in the present invention: cotton fluorescent whitening agent MST has higher whiteness and enhancing rate, the stability in hard water of excellence, acid and alkali-resistance stability and the compatibility with other finishing auxiliaries; PS-1 fluorescent Dacron whitening agent has that whiteness is high, fluorescence is strong, consumption is few, can improve printing quality, reduces production cost; Not containing 24 kinds of aromatic amines, formaldehyde, APEO forbidding in the world, asepsis environment-protecting.By both composite uses, production cost can be reduced, and better whitening effect.

Employing the invention has the beneficial effects as follows: this weaving brightening agent not only fastness to washing is good, and Heat stability is good, whiteness value are not subject to pH value impact, and whitening effect is good.

Detailed description of the invention

Below in conjunction with embodiment, the invention will be further described.
