Abstract

The invention relates to a method for dyeing pure silk by regarding a rare earth material as a mordant. The adopted technical scheme is as follows: taking a bleaching liquor according to a bath ratio of 1: (25-35) and pre-treating at a temperature of 90 DEG C; washing the pre-treated pure silk with a water washing liquor for twice to three times; dewatering and drying the pure silk; taking a dye liquor according to a bath ratio of 1: (25-35), adjusting pH of the dye liquor to 3-3.5, heating the dye liquor to 50 DEG C; adding the dried pure silk in the dye liquor and heating to 90 DEG C at a temperature rise speed of 2 DEG C per each minute, keeping the heat for 30-40 min and then cooling to 70 DEG C; and adding a rare-earth solution to soak the pure silk for 10-15 min, then heating to 90 DEG C at a temperature rise speed of 2 DEG C per each minute, keeping the heat for 30-40 min, washing with clear water for twice to three times, dewatering and drying. By adopting the method for dyeing the pure silk by regarding the rare earth material as the mordant, disclosed by the invention, color fastness requirements needed by the production of green environment-friendly textiles not only can be satisfied, but pollution from the traditional mordants to the environment can also be avoided.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for dyeing real silk by using rare earth substances as mordants. Background technique [0002] Real silk is elegant and noble, has good affinity with the skin, is comfortable and soft to wear, absorbs moisture and keeps warm, and can effectively prevent skin diseases. Dyeing with green and environment-friendly natural plant dyes can make the excellent quality of real silk more perfect and become a real "all-green fabric". The demand for "all green fabrics" will continue to increase. The application of natural plant dyes has a long history, but most of the natural plant dyes have low affinity to fibers, and must be fixed on the fibers with the help of mordants to complete the dyeing of fabrics. In the traditional mordant dyeing process, the commonly used mordant dyes are mostly heavy metal ions, such as copper, iron, chromium or aluminum. However, as some varieties of synthetic...
