How To Eliminate The Defect In Dyeing Cloth Production(一)

- Dec 20, 2017 -

A small defect, like a fly bad a pot of soup. Dyeing often encountered in the process of off color, color of color, color reproducibility, dyeing auxiliaries, dyeing, bleaching practice period of rotten cotton spots, folds, alkali spot, macular, alkali clay, wax, such as singeing folds, caterpillar printing defect.

How do you deal with such defects on a technical level? How to prevent and deal with such defects in production, so as to improve the product quality and success rate of dyeing cloth and achieve the purpose of energy saving and consumption? Starting from this issue, we will be invited for many years engaged in technical work in dyeing and printing line,Jiangsu Jinerte Textile Technology  Co., Ltd is good at  to solve the problem of printing and dyeing difficulty textile printing and dyeing.

1.How to improve the success rate?

Expert support: if it is a recurrent color that is frequently produced, the pretreatment process should be stable and consistent to ensure that the semi-finished products of each production are consistent with the same amount of white and pH value. And each time the laboratory must be used for the sample, the different batches of the dye to be used for comparison. If both of them have no problem, the success rate of the test will be high, and even the color of the color will not be tested.

Laboratory, if the production of new colour, want to make small sample confirmed, and the operator before dyeing, different sample proofing member operators at the same time, the best if two people pull the prescription then can close to the first prescription, a color test success rate is high.

Used dye production area, the force part should be determined, should not often change the dye producing area. Because each manufacturer dye quality, color stability, additives, production process is different, use different manufacturer dye can make return single first prescription gap is bigger, affect try color a success.

2.How to deal with dyeing cloth fold?

Practice folds as expert action: bleaching, see more at high density polyester and cotton fabric, in production due to water hardness, when steam wash easily scale forming adhesive on the cloth guide roller, production for a long time will form the scale the trench, make the cloth guide roller is not smooth, the fabric is easy to wrinkled. Workers in the production once found that there is a crease to clean the car in time, when dyeing the semi-finished product has the crease, should use reasonable process repair. The following is a brief introduction to the pleated reprocessing methods

If the fabric is not smooth and temporary creases or the silt of the pleats, the light will not be considered for the dyeing effect. If the dyeing is heavy, the dyeing can be dyed.

If there is a clear crease in the cloth, there is no fabric damage and the machine is black tucks. If the pleats form the fabric damage, the bottom of the machine is a white pleated seal. For this kind of pleated, the technician can use the high temperature super width to pull back to repair.

Practice to cloth folds as severe, and the crease had formed aurora on the cloth, this kind of folds more difficult, only the future for high temperature super pull to light again after wide grinding process, MAO will crease aurora smooth, drift, and cooked again make damage fabric fiber puffed repair, finally by the high concentration of alkali mercerization will crease level.

Technical personnel should accurately determine the causes of the pleated folds in the repair of the folds, and the different methods of the treatment of the folds are different in order to avoid the waste of unnecessary process. For example, the silk and light drying pleats are better to be found, and should be handled in a timely manner, so don't leave the problems until they are stained. If the pleats are not easy to handle can be played on the axis when the silk is down, so that the folding can be used to flatten out the remaining cloth and the remaining cloth will be pressed flat, so that the dyeing can be saved.
