General chemical ﹠ blended fabric is produced many on the equipment at intermittence in dyeing, it is low that intermittently equipment has power consumption, and equipment occupation space is little, and batch size is advantage flexibly, often has fluorescence colouring back machine not clean up in the production and causes.Fabric was infected with fluorescer when back road dyeed, and had a strong impact on product coloured light, caused unnecessary loss.
The nylon fabric fabric applications is extensive, and proportion is increasing in the processing of chemical fibre dyeing and finishing enterprise, and in order to reduce the loss, except paying attention to standard operation, outstanding fluorescence removal method and auxiliary agent research and development also are very important.
Utilize the procedure of the brilliant whiteness of complementary color principle increase weaving of light to be called whitening finishing, claim to add white again.Textiles through bleaching still contains yellowish material, and strengthening bleaching can the damage fiber.The utilization brightening agent can make blueness mend mutually with yellow, can improve the whiteness of textiles to fibrous zero damage the time.Method of whitening has two kinds of blueing and fluorescence.The former imposes very light blue dyes or pigment on the fabric of bleaching, so as to offsetting yellow, owing to increased the absorption to light, the brightness meeting of fabric decreases and shows slightly gloomy.And fluorescent whitening agent is near colourless organic compound, on dye behind fabric, be subjected to ultraviolet exciting and produce indigo plant, purple fluorescence, mend mutually with the gold-tinted of reflection, increase the whiteness and the brightness of fabric, effect is better than blueing.Fluorescent brightening also can be carried out with bathing in conjunction with bleaching, starching or wrinkle proofing.
Fluorescent whitening agent is a kind of fluorescent dye, or is called white dyestuff, also is a kind of organic compound of complexity.Its characteristic is to excite incident ray to produce fluorescence, make dye the sparkling effect that material obtains similar fluorite, the material that naked eyes are seen is very white, reaches the effect that brightens.Because it can significantly improve paper of whiteness, so fluorescent whitening agent is widely used in paper industry, in the production process of napkin paper, some enterprise also adopts fluorescent whitening agent to reach the effect that improves whiteness.
Fluorescent whitening agent is a kind of special powdery organic matter, can absorb the following ultraviolet light wave of 400nm, and with the power conversion that absorbs, gives off purple or the blue-fluorescence of 400～500nm, and remedies by the purple of matrix reflection loss or blue wavelength with it.Therefore we can say that fluorescent whitening agent had not only brightened but also played certain ultraviolet radiation absorption effect.Add a small amount of blue pigment in the white products in the hope of reaching the purpose of " hiding yellow ", fluorescent whitening agent is to make the increase of reverberation quantity play the effect of " adding light ", " dim light " effect that indigo plant brightens is different with adding, thereby product surface brightness is increased, make product color more clear, distinct, reach the whitening effect of " radiant ".
Nylon fabric is the most common in forms such as general Ta Silong with all size, Nylon Taffeta, OXFORD, and dyeing is based on ACID DYES.Polyamide fibre (high polymer of adipic acid and hexamethylene diamine) commonly used has certain hydrophily, the dispersion liquid of both available hydrophobic nonionic fluorescent whitening agent, available again water miscible anionic fluorescent whitening agent, nylon often brighten and carry out with oxidant bleach or sodium hydrosulfite reducing bleach.Therefore, must antioxidant and reductant.Adopt high temperature and acid treatment because of bleaching the back again, again must be heat-resisting and acidproof.So removing processing, the fluorescence of nylon fabric must select suitable removal auxiliary agent and processing method with reference to the fabric construction and the dyeability of nylon fibre.
