Shade problem in Enzyme with Stone washed of Denim Jeans in washing

Shade problem in Enzyme with Stone washed of Denim Jeans in washing: Shade matching in stone washing is a very important technique of Denim Jeans. As a result different garment from same fabric lot will result to different shades although they are processed in same conditions with same chemical recipes. Chemical quantities, temperature, time and other parameters during process controlled the shade variation. Enzymes and pumic stones are responsible to create paneling effects and white grains on garment. In modern techniques, enzyme with pumic stone helps to increase the extent…

Bleach Washing Problem

Bleach Washing Problem Bleach can be used to decolorize indigo from garments.  In this process a strong oxidative bleaching agent such as sodium hypochlorite or KMnO4 is added during the washing. De-colorization process is  usually more apparent depending on strength of the bleach liquor quantity, temperature and treatment time. It is preferable to have strong bleach with short treatment time. After bleach washing, there should be neutralization to minimize yellowing. Limitations of bleach washed in the below: Difficult to control in bleach processing time Bleach is harness chemicals so it…

Enzymatic fading effect on Garments in Washing

Enzymatic fading effect on Garments in Washing   The laccase help to fade the Jeans without affecting the weft yarns, the resulting finish exhibits unique wash-down of denim. It uses for stretch denim, without affecting its elasticity. The laccase enzyme used for abrasion enhancement by further brightening up the denim after cellulose treatment. As environmentally friendly processes consume less energy and raw materials and markedly reduce waste and water consumption. The challenge to biotechnology is to provide tools that will enable to achieve these goals and thus ensure great industrial…

GSM INCREASE OF DENIM JEANS IN WASHING

GSM INCREASE OF DENIM JEANS IN WASHING The term GSM of fabric means the weight of the fabric in grams per square meter (Weight per unit area). GSM is the most important parameter in washing.  It maintained in processing of  washing. GSM measured after each and every stages of washing. GSM cutter measured GSM. Technician can increase GSM in cotton fibers of garments. But they can not increase GSM in man made fibers. The way to reduce GSM : The GSM of garments  decreases during bleaching action with pumic stone.…

Bleach washing problem

Bleach washing problem Bleach wash is common washing process. It is a strong oxidative bleaching agent. Simply to say Bleach is a chemical that removes colors from the garments during bleach washing or bleach wash. By applying bleaching wash special type of fading effect can be produced in the garments. All types of garments can apply bleach wash.. It also help to increase soft of garments,  color fastness and rubbing fastness. Bleach washed jeans   Bleach washed jeans   Limitations of Bleach washed: Hypochlorite reduce loses strength over time, especially at…

Tensile problem in Garments Washing

Tensile problem in Garments Washing Changes of Tensile strength along with all washing and  influences adversely of garments strength. Tensile strength falls after washing in both warp and weft wise direction. Enzyme wash sample shows the lowest result.  PP washed sample is much better than others washed.   The way of techniques are used to reduce of Tensile problem : The significant important things are Gas conentration, speed and time are the main potential parameters of washing that influences mainly on the tensile strength  of the garment. Speed and time…

DIMENSIONAL STABILITY IN WASHING

DIMENSIONAL STABILITY IN WASHING Dimensional stability is the ability to resist shrinkage or stretching of garments . Simply say to measure of garments after washing. There are mainly three factors that could cause dimensional changes are: Tension Swelling (Felting, wool) Tension is one important elements to change  the dimensional stability. Tensions generally occur during construction when yarns are held stretched. The moisture is also affect to change dimension of garments . The degree of dimensional change at relaxation depends on weave type, both in warp, weft and on total shrinkage.…

Yellowish Problem in denim jeans washing

Yellowish Problem in denim jeans washing Yellowing of garments become many reasons.  The techniques need to prevent Yellowish Problem jeans washing. Sometimes, fabric yellowing indicates fabric low quality so the fabric may fix this problem. Proper treatment of garments are the keys to minimizing losses from yellowing. The below discussion possibly come yellowish on garments. 1.FIBER DEGRADATION Excessive heat creates yellowish problem in washing. Especially in the presence of high humidity, high exposure to ultraviolet light, or long term storage .  2. CHEMICAL ADDITIVES OR AUXILLARIES Yellowish resists Optical brightening…

Lycra problem in denim jeans washing

Lycra problem in denim jeans washing It is a common problem in Jeans washing. There are many reasons behind this Problem.  But mainly two reasons are the below Lycra or spandex breaks out in washing : This lycra problem is not primarily detected while washing processing but it is visible extensively just after garments washing. Lycra is break out in excessive temperature either in heated chamber or in steam compartment. It is very sensitive to alkali, chlorine bleach and abrasion as well. Spandex filaments can be missed through the width…

Color Enhancer in Washing

Color Enhancer in Washing   From light to depth color in washing requires by buyers. Color strength of jeans decreased significantly to bleach wash and PP wash. It also decreased color strength of garments.  A portion of the primary wall of cotton is always in contact with enzyme during washing and hence at the contact point, surface of fibers are decomposed by the aqueous solution of the enzyme. some times color enhancer in washing reduce after garments washing. Color of garments become dull and fade in enzyme washing. But adverse effect…

Zipper Protector in Washing

Zipper  (Metal) Protector in Washing There are many garment washed to achieve the desirable effects.  However, garment washing may have adverse effects on the quality of metal. Problem of Metal in washing processing and effective measure should take to provide more protection in each and every process.  Metal Damage in Garment washing If the metal zippers did not zipped up in washing then Zipper would damage. The collision and friction caused by the washing drum can bring abrasion to the metal of Garments. It will damage metal of Garments.  …

TEAR STRENGTH PROBLEM

TEAR STRENGTH PROBLEM The garments shows  its ability to resist a tearing force . It is an important property for the durability of garments.  It indicates of the strength of the yarn of garments. The tear strength of garments will decrease after washing, and that loss of durability. The differences between pre washed, stone washed, bleach washed, PP washed,  and enzyme washed, and the strength loss was found to be different. but  It was also found that in cases where softeners were used during laundering, the decrease of tear strength…
