How To Control The Washing Quality Of Denim Clothing

As we all know, the following quality problems are very likely to occur during the washing process of denim: background color deviation, sand position shading, whisker weight, fabric treatment, etc. There are many reasons for these problems. Once discovered, the reasons should be found and corrected in time.

The background color has an impact. Due to the above complex reasons, there are no strict standards for the washing process of denim. In many cases, the washing master has to develop a corresponding washing plan according to the specific conditions of the fabric, and the employees only ask and follow the washing master's requirements to wash, so there are many uncontrollable factors. Too many, and the washing quality is difficult to control.

There are three situations when there are problems with the background color of denim clothing: dark background color, light background color and mixed background color. If the background color is dark, the washing plan needs to be re-formulated based on the specific situation, so that the denim garments can achieve the background color effect of the sample after being washed, and then dehydrated, hung, and returned to drying; if the background color is light, water treatment is required. It is difficult to wash back the color, so the base color should be darker rather than lighter when washing with water for the first time.

In order to improve the pass rate of denim washing base color, the following improvements must be made: the proofing room formulates reasonable washing process standards based on the sample clothes provided by customers; tracks the production status of the bulkhead vat, and strictly monitors the production progress and process conditions of the bulkhead vat. Based on the washing effect, make timely improvements and formulate more reasonable washing process standards; color separation of large quantities of goods before washing, and if the color difference is large, wash them separately; the washing master carefully checks the version and accurately conveys his information to the washing staff to achieve Answer all questions; the washers operate in strict accordance with the washing process standards and check the progress at any time during the washing process; explain the washing equipment, washing auxiliaries, dye functions and safety to the new washing employees, so as to make employees aware of the impact of auxiliaries on Impact on quality; strengthen training for washing personnel and improve their quality awareness.

Cat whiskers weight

The cat whiskers mentioned here generally refer to hand-wiping cat whiskers. Since the working environment of hand-wiping cat whiskers is poor, and the process is both physical and technical, the hand-wiping personnel must rub according to the powder traces of the previous process. , the strength, position, and frequency of hand rubbing will all affect the effect of the cat whiskers after washing. The working status of employees varies greatly at different time periods. Long-term work fatigue will inevitably lead to difficulty in controlling strength, poor mental state, and severe whiskers.

Through analysis, improvements can be made through the following methods:

(1) Strengthen ventilation and lighting facilities in the operation workshop to improve the working environment;

(2) Due to long-term high-intensity work, resulting in physical and mental exhaustion, the hand-wiping workshop can organize exercises at noon and afternoon every day to soothe the muscles and bones;

(3) Workshops should try to select men for hand cleaning work;

(4) In the case of two people working together, a hand-wiping test should be carried out before arranging production, and employees with similar hand-wiping strength should be selected to jointly operate;

(5) Increase supervision and inspection during the production process and make continuous improvements.

Fabric Treatment

The reason for the discount problem caused by washing large quantities of jeans is mainly caused by hand wiping, and the hand wiping work itself is relatively hard, and the workers' physical strength decreases due to long-term fatigue, and there are many uncontrollable factors. Of course, the washing process will also cause discount problems. Factors such as excessive water-to-bath ratio, uneven speed of the washing machine, etc. will affect it. The analysis of the discount problem is as follows:

From the fishbone diagram above we can find the control method for the corresponding discount problem:

(1) Sandpaper specification control;

(2) The hand wiping equipment is stable and the clothing is fixed and flat;

(3) Hand wiping strength and position specifications;

(4) Thoroughly clean and cut clothing threads;

(5) The workload of employees should be moderate and breaks should be increased.

Other washing quality issues

(1) Leakage process. During the washing process, multiple manual processes such as hand wiping, folding, and mowing are required. Especially when there are many hand wiping steps, the process must be ensured to be complete.

(2) Size deviation. During the washing process, the washing temperature and time and the drying temperature and drying time will all affect the size of the clothing. It is necessary to unify the requirements, conduct shrinkage experiments on fabrics according to post-processing methods, and prepare fabric samples in advance to increase shrinkage.

In short, DEMIJEANS is a denim fabric manufacturer that has certain equipment to produce the best denim fabrics at low prices.
