Abstract
The invention relates to the field of fine modification of fibrilia, in particular to a functional additive for fibrilia modification and one-bath bleaching and a preparation method thereof. The functional additive mainly comprises the following components: natural clay, C6H12O12N2P4Na8, alkyl polyglucoside, secondary alkyl sodium sulfonate and pure water. Compared with the prior art, the functional additive has the beneficial effects that: (1) the softness of the fiber is nearly doubled after modification, the elongation at break of the fiber is increased by over 20 percent, the capillary effect is increased by over 30 percent, the whiteness is similar to that of the conventional process, and the degree of dyeing is increased by over 30 percent; (2) the modified residual solution can be recycled after being precipitated statically, and the discharge of sewage caused by modification and bleaching is avoided; and (3) the functional additive has high adaptability and is applicable to fibrilia such as flax, industrial hemp, jute, kendir, nettle, pineapple fiber, ramie and kenaf.
Description
Technical field
The present invention relates to become more meticulous modification and improve the weaving such as numb pliability, dye uptake, crimpness, division degree, hygroscopicity chemical products field of flax fibre, particularly a kind of for fibrilia modified and with bathing function additive of bleaching and preparation method thereof.
Background technology
Flax fibre raising feel with division degree after coming unstuck becomes soft gradually, but still, Boardy Feeling larger than cotton fiber rigidity.General all for low-grade tatting product, for making flax fibre for medium-to-high grade knit product, must make flax fibre significantly improve the performances such as elasticity, extension at break, crease-resistant, dye uptake, moisture absorption, reduce the rigidity of flax fibre thoroughly to improve flax fibre pliability, must pass through the modified technique that becomes more meticulous.
Summary of the invention
It is a kind of for function additive fibrilia modified and that bleach with bath and preparation method thereof that object of the present invention provides, overcome the deficiencies in the prior art, coordinate existing concentrated base and hydrogen peroxide production technology, improve performance and whiteness after fibrilia modified, the discharge capacity of Wastewater Pollutant after minimizing modification, the environmental-protecting performance of raising production technology.
For solving the problems of the technologies described above, technical scheme of the present invention is:
For function additive fibrilia modified and that bleach with bath, mainly by following compositions in weight percentage, formed:
Natural clay (SiO

81-5％，
APG 1-7%,
Seconary Alkane Sulphonate Sodium 0.5-5%,
Pure water salt content is lower than 10ppm surplus, and said components summation is 100%.
The described preparation method for function additive fibrilia modified and that bleach with bath, in stainless steel or enamel reactor, first add in recipe ingredient all natural claies of pure water and wet purification, under room temperature condition, with stainless steel agitator, stir 3-12 hour, then under stirring condition, by the order of formula, add successively surplus material, adjacent component interval is no less than 10 minutes, then continues to stir 0.5-2 hour.
Compared with prior art, the invention has the beneficial effects as follows:
1) performances such as the elasticity, extension at break of flax fibre, crease-resistant, dye uptake, moisture absorption have significantly been improved, reduce the rigidity of flax fibre thoroughly to improve flax fibre pliability, after modification, improve one times of left and right of fiber flexibility, improve the extension at break of fiber more than 20%, capillary effect improves more than 30%, whiteness and common process are close, improve dye uptake more than 30%.
2) coordinate existing concentrated base and hydrogen peroxide treatment process, not only improve the performance after fibrilia modified, and improved the whiteness of flax fibre after modification, significantly reduce the pollutant of waste water after modification, improved the environmental-protecting performance of production technology, the present invention is applied to numb modification and bleaching one-bath processing, can make the raffinate colourity after modification significantly improve, this auxiliary agent has absorption and self-cleaning function, and the raffinate after modification can recycling after quiescent setting.Exempted the sewage discharge of modification and bleaching.
3) to various fibrilia modified strong adaptabilities, flax fibre applicatory has flax, industrial hemp, jute, bluish dogbane, nettle, pineapple fibre, ramie, bluish dogbane etc.
