Problems solved by technology

However, silk is easy to shrink, wrinkle, and difficult to take care of, which has always troubled people who use them.
With the development of science and technology, many kinds of silk fabrics have realized the function of machine washing; but the goal of machine washing of organza fabrics is still difficult to achieve
Due to the special structure of organza fabrics, processing is relatively difficult, color fastness and stability are poor, and it is easy to fade and deform after washing. The invention provides a dyeing and finishing process for silk organza fabrics, which improves the quality of organza fabrics. Excellent color fastness and wrinkle resistance, machine washable

Abstract

The invention discloses a process for dyeing and finishing a machine-washable silk organza fabric. According to the process, a fabric is subjected to granite-wash with vesuvianite, and the silk fibers with smooth fabric surface are ground into a slightly uneven shape, so that the dye-uptake and fixation rate can be improved; the color of granite-washed silk may be changed, which brings a visual perception different from that of a traditional organza fabric; the ultraviolet protection of the granite-washed fabric can be remarkably reinforced; the granite-wash condition should be strictly controlled to prevent the fabric service life from being influenced due to the fact that silk fibers are seriously destroyed by granite wash, the vesuvianite size, ultrasonic frequency, power, time and temperature are strictly limited; and vegetable dye, surfactant, a chelating agent, dispersant and accelerant are added in the dyeing stage, so that the fabric has very good color fastness and wrinkle resistance to meet the requirement of machine washing.

Description

technical field [0001] The invention relates to a process for treating real silk fabrics, which belongs to the field of textiles, in particular to a process for dyeing and finishing machine-washable silk organza fabrics. Background technique [0002] Organza is a kind of transparent or translucent gauze, which is the main raw material in wedding dresses of Europeans such as France and Italy, and is often covered with satin or silk. It is characterized by lightness and flow, very thin and transparent, with a slightly firm feel, suitable for puffy contours. Traditional organza is all silk, but now many organza fabrics are made of chemical fibers, such as silk, nylon, acetate, rayon, etc., and are widely used in wedding dresses, pajamas, masks, packaging fabrics, curtains etc. [0003] Organza has ordinary organza and silk organza. The difference is that one is chemical fiber and the other is real silk. Silk organza is subdivided into a kind of silk series fabrics. It has a c...
