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.…

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.…

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…

Sulfur black denim fading problem

Sulfur black denim fading: Sulfur black denim fading is the art of washing industries. It  is an important how to fade sulfur dyes denim and there are some limitations and techniques the way to reduce fading problem in washing. Unfortunately, sulfur black dyeing of cotton on continuous machines usually results in significant problems that cause customer dissatisfaction. Denim washing is one of the key areas in getting the faded look. Sulfurs dyes attached to cotton at a faster rate than water. There are variables such as temperature, ph, ORP, moisture,…

Potassium Permanganate Activator Problem

Potassium Permanganate Activator Problem It make to solution with PP. Potassium Permanganate (PP) is an oxidizing agent to use for value added activities in the washing plant to meet buyer requirements. The Solution Potassium Permanganate 50% and PP Activator 50% of total dosage. PP spray uses on jeans to lighten a specific area and create whisker effects on denim. Using  potassium permanganate for acid wash. The solution of potassium permanganate ranging from 0.10 gm per liter to 5.00 gm per liter usages in normal productions. Low air pressure will produce…
