In this article we are going to learn about the mercerizing common problems and its solution.
1) Color deviation to the left and right
A The pretreatment on the left and right sides of the cloth do not correspond, resulting in uneven alkali content throughout the fabric.
B different amount of alkali is present in various sections of the rolling groove.
C Due to the air cylinder's inflexibility and general wear and tear, there is a disparity in the amount of liquid between the left and right sides of the fabric.
Due to D's increase, the acid-base ratio on the right side no longer agrees with the one on the left.
Inadequate clean - up, which brings us to E.
2) The fabric shrank excessively in both the warp and the weft.
A high concentration of base is a problem. The expansion of B is insufficient (the tension is too great during feeding), which makes expanding in the weft direction challenging (weft shrinkage of thin textiles).
C There is insufficient tension between the two base rollers, and as a result, the fabric is not properly mercerized or sized.
D The fabric has a high alkali content and a weak alkali leaching effect. When washed in hot, alkaline water, the fabric will shrink.
Because of (E), both the equipment tension and the fabric's weft shrinkage are excessive.
3) Holes and frayed edges
A piece of fabric is worn or rigid.
B The tension on the fabric is variable and uneven.
C The door to the clothing outlet is excessively broad.
D Either the speed or magnitude of the magnification is excessive.
E The equipment used to detect edges or facilitate growth is rigid.
When a cloth is scoured and bleached, the remaining surfactant is neutralized by the alkali, and the fabric's lipophilic groups congregate to contaminate it, resulting in light areas where the dye has been deposited locally.
Mercerizing process requires attention
1. a mercerized cloth must have the same degree of slubber while wet and dry. Fabrics created from polyester and cotton are rolled at 50% tension while those made from cotton and linen are rolled at 60% tension during the wet mercerizing process.
2. To keep the mercerized alkali fluid at a constant temperature, the fabric must be cooled through the ventilation frame after the dry cloth has been mercerized.
3. mercerization requires tension between the fabric's warp and weft. When the tension is increased, the fabric's sheen improves, and its size and temperature rise.
4. in the mercerizing procedure, the fabric must be kept flat to avoid curling and wrinkling. Once an identical test must be performed, mercerizing is required.
5. Using grey mercerization or mercerizing after mercerizing is commonplace in the mercerizing process for knits. Fabrics' weak water absorption necessitates the application of penetrant to improve the mercerizing impact of concentrated caustic liquor.
6. For the best results, check the mercerizing cloth's pH using a variety of indicators or test sheets. If necessary, neutralize the fabric with acid during the washing process to keep it as neutral as feasible.
7. The human skin can easily corroded and burned by powerful caustic soda (concentrated acid), which is why it is so dangerous. Anyone who might come into touch with powerful lye (concentrated acid liquor) should wear the appropriate safety gear. Splashing lye (or acid) on your skin or in your eyes? Wash it off with water and see a doctor if it doesn't go away.
Thanks for patiently reading my article. In this part of article I’ll suggest a Mercerizing Penetrant product from Dongguan Taiyang Textile Chemicals Co., Ltd. Which is simply best in the market. See you in the next article.
