Description
Technical Field
The invention belongs to the field of dyeing, and relates to a dyeing process of a safe fabric for infants.
Background
The wearing object of the infant fabric is an infant in 0-1 year old, the skin of the infant is delicate, the body surface temperature is incompletely regulated, the resistance is poor, the infant cannot flexibly turn over due to small sleeping time, the infant easily suffers from eczema due to excessive sweating, and if the harmful substances of the fabric which do not meet the standard are selected, the infant is easily attacked through the skin of the infant, and the infection chance is increased. As a protected group, the fabric for infants is selected not only to protect the body from mild injury, but also to satisfy the safety of the fabric. However, the infant textiles and other clothes textiles are subjected to a plurality of physical and chemical processing processes from raw materials to final products, so that the problems of environmental pollution and textile safety are inevitably brought in the production process. In recent years, problems of toxic dye, excessive formaldehyde and excessive pH of the children's clothes often occur.
Natural dyes are receiving increasing attention because of the certain harm they pose to the human body. The natural dye is non-toxic and ecological, has soft color, is natural and distinctive, and has good environmental compatibility and drug health care performance. Therefore, there is a need to develop a dyeing process for baby safety fabrics, which reduces the contact of harmful substances with babies and improves the safety of taking.
Disclosure of Invention
In view of the problems of the prior art, the invention aims to provide a dyeing process for a safe fabric for infants, which reduces the contact possibility of harmful substances with infants and improves the safety of taking.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a dyeing process of a safe fabric for infants comprises the following steps: (1) emerald taking the dye; (2) preparing a liquid; (3) dyeing at a bath ratio of 1: 20; (4) mordant dyeing is carried out by adopting loess powder with the concentration of 5g/L and the temperature of 40 ℃.
Further, the dye extraction comprises a madder extraction process and/or a sappan extraction process.
Further, the madder extraction process comprises the steps of weighing 5g, 10 g, 15g and 20 g of madder respectively, adding the madder respectively into l L distilled water, soaking for 24 hours, then placing the madder into a water bath kettle, heating to boil, decocting, pouring out liquid when water is evaporated to l 00mL, repeating twice, collecting, mixing and filtering the liquid, and evaporating to 50mL under reflux to serve as plant dye for later use.
Further, the sappan wood extraction process comprises the following steps: respectively weighing 5g, 10 g, 15g and 20 g of sappan wood, respectively adding the sappan wood into I L distilled water, heating and extracting dye liquor with the concentration of 5g/L, 10 g/L, 15g/L and 20 g/L by using a distiller, standing and cooling the dye liquor after extraction is finished, and filtering for multiple times.
The invention has the following advantages: the dyeing process adopts natural plant dye for dyeing, and uses pure natural mordant for fixation, thereby not only achieving the effect of enriching the color of the fabric, but also improving the safety of the infant. The measured formaldehyde content value completely reaches the range of the national defined infant product formaldehyde content 200mg/kg requirement; but also avoids chemical pollution of synthetic dye, and is beneficial to environmental protection and human health. For hematoxylin and madder staining, the mordant staining of loess can reduce the color difference value after staining, and the color becomes softer. P H of the madder and the sappan wood staining substance are both in the range of 6-7, which meets the national quality inspection requirements. In the case of madder, the dye uptake increased with decreasing p H value, but at the same time, considering the skin-friendly nature of the fabric, the dye p H value was adjusted to be around 6 of the meta-acid. The loess mordant dyeing has color fixing effect on the dyeing of sappan wood and madder, so that the water washing resistance is obviously improved, and the level 2 can be improved.
