They are easy to be adsorbed on fabrics, but they are prone to yellowing and discoloration, which affects the hydrophilicity. If the cationic soft sheets are modified into soft olein, the yellowing will be greatly reduced and the hydrophilicity will be reduced. Improvement, such as compounding cationic film with hydrophilic silicone oil, or compounding with hydrophilic finishing agent, its hydrophilicity will be improved \ufffd<\/p<\/p>\n

\n 1.3 Decreased hydrophilicity of fabric<\/p<\/p>\n
\n Generally, the structural problems of the film used, the lack of water-absorbing groups after the silicone oil film is formed, and the blocking of water-absorbing centers such as the hydroxyl groups of cellulose fibers, carboxyl groups, and amino groups on wool cause a decrease in water absorption. Anionic and non-ionic products should be used as much as possible. Soft and hydrophilic silicone oils \ufffd<\/p<\/p>\n
\n 1\u00b74 dark spots<\/p<\/p>\n
\n The main reason for dark spots is that the oil and sewage on the fabric is removed during pre-treatment, and the oil stain is darker in color during dyeing; or there is too much foam in the dyeing process, and the mixture of foam, floral fabrics, dyes, etc. is stained on the fabric; or the defoaming agent floats Oil causes dark oil spots; or tar-like objects in the dye vat stain the fabric; or the dye agglomerates under different circumstances to form dark stains; or excessive calcium and magnesium ions in the water combine with the dye and stain the fabric, etc. \ufffd\u8981\u9488\u5bf9\u6027\u8fdb\u884c\u5904\u7406\uff0c\u5982\u524d\u5904\u7406\u65f6\u52a0\u53bb\u6cb9\u5242\u8fdb\u884c\u7cbe\u7ec3\uff0c\u67d3\u8272\u52a9\u5242\u91c7\u7528\u4f4e\u6ce1\u3001\u65e0\u6ce1\u52a9\u5242\uff0c\u6d88<\/p<\/p>\n

\n 1\u00b75 light spots<\/p<\/p>\n
\n The main reason for light stains is uneven pre-treatment, poor hair effect in some parts, resulting in a certain degree of dye repellency, or containing dye-repellent substances, or the cloth contains calcium soap, magnesium soap, etc. during pre-treatment, or The mercerization is uneven, or the drying of semi-finished products is uneven, or the cloth surface is stained with undissolved Yuanming powder, soda ash and other solids, or water is dripping on the dyed material before drying, or there are spots of additives during post-finishing such as softening the dyed material. stain Similarly, targeted treatment is necessary, such as strengthening pre-treatment. When selecting pre-treatment additives, it must be difficult to form calcium magnesium soap, and pre-treatment must be uniform and thorough (this is related to the selection of scouring agents, penetrants, chelating dispersants, mercerizing penetrants, etc. ), Yuan Ming powder, soda ash, etc. must be melted into the tank and production management must be strengthened. \ufffd<\/p<\/p>\n

\n 1\u00b77 Softener Collapse<\/p<\/p>\n
\n The causes of softener stains may be as follows:<\/p<\/p>\n
\n (1) The soft flaking material is not good, and there are lumps of softener adhering to the fabric; <\/p<\/p>\n
\n (2) There is too much foam after the material is softened into sheets. When the cloth comes out of the vat, the cloth will be stained with softener foam; <\/p<\/p>\n

These substances form floc with impurities in the water, and after entering the softening treatment bath, the cloth surface will be stained; <\/ p<\/p>\n
\n (4) The cloth surface contains anionic substances, which combine with the cationic softener to form stains when softened, or the cloth surface contains alkali, which causes the softener to agglomerate; <\/p<\/p>\n
\n (5) Softeners have different structures, and some may cause the softener to change from an emulsified state to a slag-like substance that adheres to the fabric at higher temperatures; <\/p<\/p>\n

\n 1\u00b78 Silicone oil stains<\/p<\/p>\n
\n Silicone oil stains are a type of stain that is difficult to treat. The main reasons are: <\/p<\/p>\n
\n (1) The pH value of the cloth surface is not neutral, especially if it contains alkali, causing the silicone oil to break and float; <\/p<\/p>\n
\n (2) The water quality of the treatment bath is too poor and the hardness is too high. Silicone oil can easily float in water with a hardness greater than 15Omg\/L; <\/p<\/p>\n

\n 1\u00b79 Poor fluff<\/p<\/p>\n
\n Poor raising is closely related to the operation of the raising machine (such as tension control, raising roller speed, etc.). For raising, when applying softener (commonly known as waxing), controlling the dynamic and static friction coefficients of the fabric is the key, so the raising is soft. The preparation of the softener is key. If the softener is not used properly, it will directly cause poor fluffing, and even cause tearing or door width changes. \ufffd<\/p<\/p>\n

\n 3.2 Color change problem<\/p<\/p>\n
\n After post-finishing, there are many problems with color changes. This requires attention to the selection of dyes during dyeing. During dyeing, corresponding post-finishing must be carried out according to the process to determine whether the selected dyes will cause color changes under the action of additives. Discoloration, of course, is a good choice for post-processing that will not cause discoloration. Agent is an ideal solution, but this often has limitations (for example, copper-containing antibacterial agents themselves have colors, and chromium-containing antibacterial agents also have colors, which will cause discoloration of fabrics). At the same time, the dyes must also be taken into consideration when the dyed fabrics are dried and baked. Factors such as light color and discoloration caused by sublimation and yellowing caused by excessive temperature \ufffd<\/p<\/p>\n
