Common problems and difficulties in washing
- Wash can be a complicated process, with a lot of factors involved which effects the end result. For instance different chemicals and machines are use, time and temperature are important factors. Also some processes are manual and result will vary from person to person.
- This means that the end result can sometimes be difficult to predict; chemicals can react with each other, many effects of one treatment will not be seen until the final wash is done etc. Therefore many tries may be need before we know what the best treatment is to get your requested look on your chosen fabric and color.
- And for example if the color is changed, we might need to use a different wash to get the same result as on the color you first wanted.
- The easiest way to get the good result quickly is to give us a reference cutting of the look you want.
- Then we and the supplier can choose which wash will be suitable to achieve that result on your colors and fabric.
- Difficulties to get the effect to stay after customer wash, for example tint.
- Colour bleeding
- Heavy treatments makes fabric weaker so it can break
- Sharp edges at scraping/blasting areas
- Dry rubbing problems
AFTER TREATMENT (WASH)/WRINKLE FREE-
• Review if Shade Mat for washed product (denims, piece dyed fabric) were done prior to cutting, while Shade Band has been established by factory or with involvement of PEI QA. Ensure that shade band is not too wide and close to approved standard.
• Ensure that bulk garment Color is within shade band/standard.
• Review if Hand feel and appearance is matching to original standard.
• For all product with Wrinkle Free, No Iron, Wrinkle Resistant etc call outs, send garments from every 2000 pcs per color to local approved lab for DP rating by filling the TEST REQUEST FORM
• Review seam smoothness on bulk garments if product is acceptable to standard. (Use AATCC replicas for comparison)
• Review fabric smoothness on bulk garments is acceptable when compared to standard.(Use AATCC replicas for comparison)
• In the case of bottoms with crease, ensure crease retention is acceptable on bulk garments when compared to standard. (Use AATCC replicas for comparison).
• QCs must keep records of GES (Garment Evaluation Sheet) of each color.
There are different types of wet processing procedures for ready made garments:
B1. Garments wash, for denim this is referred to as rinse wash
B2. Sand Wash
B3. Silicon Wash
B4. Stone Wash
B5. Enzyme Wash
B6. Acid Wash / Salt Wash
B7. Bleach Wash
The wet processes are commonly used together, for example enzyme + stone wash.
Last in this chapter you will get an explanation on common combinations
and the result they will give.
In the following pages you will get a short description on each of these washes,
and some videos showing how the process is done.
