The term finishing, in a broad sense it covers all the processes of making the fabric good looking, good hand feeling, luster and of course for buyer requirement. It is done after dying and before delivery to market. Various types of parameters are controlled during finishing section considering buyer requirement. The term also includes bleaching, dyeing, mercerizing etc. But normally the term is restricted to the final stage in the sequence of treatment of Knit fabrics after bleaching and dyeing. However, fabrics which are neither bleached nor dyed are also finished.
(Over Dyeing) to dye for a second or third time with a different color. Over dyeing is such a rewarding way of rescuing an ugly or unsatisfactory colored cloth. It gives uneven look. sometimes over dyeing doesn’t mean all-time dyeing the garment which is previously dyed. Over dyeing may be normal dyeing or piece dyeing process.

Weft knitting machine & parameters of weft knitted fabricAzmir Latif Beg
Knitting is the interloping of yarn which is interlocking in various ways to form fabric. Knitting is the process of manufacturing fabric by transforming continuous strands of yarn into a series of interlocking loops, each row of such loops hanging from the one immediately preceding it. The basic element of knit fabric structure is the loop intermeshed with the loop adjacent to it on both sides and above and below it.
A wrinkle, also known as a rhytide, is a fold, ridge or crease in the cloth or garments. Wrinkle is a particular type of pressure in the finished fabric. It is produced during finishing operations by the thickness of the seam used to join pieces for processing.Resin & its use in Denim garments industry to create unique & vintage looks which add value to denim garments & improves it sale ability in market. In 80’s we have seen Resin being used to give non press , iron free trousers & now we are using in Denims to make wrinkles & creases to look natural vintage which stays after multiple home laundries.
Wrinkle resistance varies from quite low in many fabrics to very high in resilient fabrics. In order to form a wrinkle, a fabric’s wrinkle resistance must be overcome. The fabric may, however, produce strains and store potential energy that can become evident as wrinkle recovery under suitable conditions.Resin & its use in Denim garments industry to create unique & vintage looks which add value to denim garments & improves it sale ability in market. In 80’s we have seen Resin being used to give non press , iron free trousers & now we are using in Denims to make wrinkles & creases to look natural vintage which stays after multiple home laundries.
Jigs exert considerable lengthwise tension on the fabric and are more suitable for the dyeing of woven than knitted fabrics. Since the fabric is handled in open-width, a jig is very suitable for fabrics which crease when dyed in rope form. Jigg or jigger dyeing machine is the most commonly used for dyeing all kinds of cotton fabric. There are mainly two types of jigger dyeing machine

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

processes of making the fabric good looking, good hand
feeling, luster and of course for buyer requirement. It
is done after dying and before delivery to market.
Various types of parameters are controlled during
finishing section considering buyer requirement. The
term also includes bleaching, dyeing, mercerizing etc.
But normally the term is restricted to the final stage in
the sequence of treatment of Knit fabrics after
bleaching and dyeing. However, fabrics which are
neither bleached nor dyed are also finished.
8. Objects of finishing:

To control the dia.
To control the shrinkage. (Increase & decrease).
30. Special note on compactor finishing:
In case of light color padder pressure should be low.
Otherwise shade will be lighter.
If the padder is not clean, then line mark can appear in the
fabric.
Fabric dia, extension, speed, compaction & overfeed will
vary depending on the fabric type and finishing
requirements.
In the case of low GSM S/J fabric padder pressure and
speed will be maximum.
In the case of high GSM S/J fabric then padder pressure and
speed will be minimum.
In case of Lycra single jersey fabric, speed & padder
pressure will be minimum.
