A kind of preparation method of multifunctional colored real silk or wool fabric

Abstract

The present invention relates to a kind of preparation method of multifunctional colored real silk or woolen fabric, adopts Fe-containing 3+ The solution is used to finish silk or wool fabrics to make multifunctional colored silk or wool fabrics, wherein the finishing method is dipping, and the finishing temperature is 70-80°C. The superhydrophobic contact angle of the prepared multifunctional colored silk fabric is ≥163.5°, the LOI is ≥36.6%, the UPF value is ≥17.56, the UVA value is ≤6.70%, and the UVB value is ≤6.80%; the superhydrophobic contact angle of the multifunctional colored wool fabric is ≥ 159.4°, the LOI of multifunctional colored wool fabric is ≥32.5%, the UPF value is ≥236.16, the UVA value is ≤0.70%, and the UVB value is ≤0.74%. The inventive method is by depositing a large amount of Fe at real silk or wool fabric 3+ , significantly improved its flame retardant performance, hydrophobic performance and anti-ultraviolet performance, and the functional finishing effect is good.

Description

technical field [0001] The invention belongs to the technical field of textile functional finishing, and relates to a preparation method of multifunctional colored silk or wool fabric. Background technique [0002] As a kind of natural fiber, real silk fabric has excellent comfort, soft luster and soft feel, and has excellent moisture absorption and breathability and health care performance, etc., and is widely used in the preparation of interior decoration products such as curtains and lighting decorations. Wool is a natural high polymer containing protein. Because of its good hygroscopicity, heat preservation and comfort, it is widely used in clothing, construction and home textiles and other fields. [0003] Silk and wool have high nitrogen content, which endows them with certain flame retardancy, but with the wide application of silk and wool in various fields, its natural flame retardancy has become more and more difficult to meet people's needs, especially It is the a...

AI Technical Summary

Problems solved by technology

Silk and wool have better comfort and warmth retention properties, and are ideal fabrics for outdoor clothing, but their water repellency and UV resistance are not good, so they need to be functionally finished

The prior art discloses a colored flame-retardant and water-repellent real silk fabric and a preparation method thereof, including the following steps: (1) soaking the real silk fabric in an aqueous solution of dopamine for shaking treatment, then taking it out for washing and drying to obtain a colored fabric containing polydopamine; real silk fabric; (2) immerse the colored real silk fabric obtained in step (1) in the fluorozirconate aqueous solution, make the polydopamine on the colored real silk fabric react with fluorozirconate, then take out cold water and rinse and dry to obtain colored Flame-retardant and water-repellent silk fabrics; the prior art also discloses a preparation method of a multifunctional silk-containing fabric, first using dopamine aqueous solution to impregnate the silk-containing fabric, then using a reducing agent to impregnate it, and finally using a metal compound solution to The fabric treated with the reducing agent is dipped and finished to make a multifunctional silk-containing fabric. The LOI value of the finally obtained multifunctional silk-containing fabric is ≥29.1%, its UPF value is ≥10.79, and its contact angle is ≥128.5°. However, it is more cumbersome, and the water-repellent and flame-retardant performance of the obtained silk is relatively low, and the functional finishing effect is poor.
