Description

Technical Field

[0001] The invention relates to the technical field of fiber textile, in particular to a sustainable fiber dyeing test method. Background Art

[0002] Using natural plants or crops as raw materials, high-purity monomers are prepared through genetic engineering, microbial fermentation, filtration, purification and other processes, and polymers with a certain molecular weight are obtained through polymerization reaction. Bio-based synthetic fibers prepared through melt spinning technology have the properties of natural antibacterial, ecological and environmental protection, human affinity, and waste biodegradability. They are widely used in various fields such as clothing, home textiles, and industrial use, and have broad development prospects. "MAMI'S" sustainable aerogel fiber extracted from corn fiber belongs to the category of bio-based textile materials. "MAMI'S" sustainable aerogel fiber contains very dense nano-voids and the same fineness and strength as wool fiber. It is 36% lighter than wool and 25% warmer than wool. Textiles produced with it can reduce carbon footprint by at least 40%, and it is the best choice to replace wool and blend with wool.

[0078] 1. "MAMI'S" fiber can be dyed with disperse or cationic dyes in medium and light colors to expand the color range, solving the problem of "MAMI'S" fiber being difficult to dye and having a single color.

[0079] 2. "MAMI'S" fiber is dyed with cationic dyes in medium and light colors. The advantages are bright colors and decent soap fastness. The disadvantage is that the perspiration fastness is poor and sweat fastness needs to be improved by adding perspiration additives.

[0080] 3. "MAMI'S" fiber is dyed with disperse dyes in medium and light colors. The advantage is that it can be dyed at room temperature of 98℃, and no reduction cleaning is required for post-treatment. The perspiration fastness is better than that of cationic dyes. The disadvantage is that the color is darker and the dyeing rate is lower than that of cationic dyes.

[0081] 4. "MAMI'S" fibers are dyed with disperse dyes or cationic dyes in medium and light colors. The dyes are metal-free and the products fully meet Stamdard 100 standard, meeting the requirements of green and environmentally friendly textiles.

[0082] 5. "MAMI'S" fiber can be dyed with medium and light colors using cationic disperse dyes or ionic dyes. The dyeing process is easy and the fiber damage is minimal.

[0083] In summary, the new "MAMI'S" sustainable aerogel fiber can be dyed with disperse and cationic dyes, which can solve the problem that the fiber is not easy to dye and has a single color. "MAMI'S" fiber is dyed with cationic dyes for medium and light colors. The advantages are bright colors and decent soap fastness. The disadvantage is that the sweat fastness is poor and sweat fastness needs to be added to improve it. "MAMI'S" fiber is dyed with disperse dyes for medium and light colors. The advantage is that it can be dyed at 98°C at room temperature, and post-treatment does not require reduction cleaning. The sweat fastness is better than that of cationic dyes. The disadvantage is that the color is darker and the dyeing rate is lower than that of cationic dyes. Both dyes do not contain heavy metals and can meet the demand that products do not contain heavy metals. However, "MAMI'S" fiber is dyed with cationic dyes for medium and light colors, and the sweat fastness is poor and can only reach about level 2, so sweat fastness needs to be added to improve it. Compared with "MAMI'S" fiber dyed with disperse dyes for medium and light colors, it can be dyed at 98℃, and there is no need for reduction cleaning in post-treatment. The perspiration fastness can meet the requirements, and the fiber damage is low during the dyeing process. The operation is simple. The dark color can be solved by choosing dyes with good brightness, and the dyed product fully meets the requirements. Stamdard100 standard.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
