  1. Pigments are not soluble in water
  2. Pigments are also not soluble in acid and
  3. Pigments don’t have addiction with fiber so these pigments are attached with fiber or cloth by binder.
  4. Wet fastness and light fastness are good but rubbing fastness is not good for heavy shade.
  5. Pigments can gives us the bright and ideal shade from any color.
  6. Pigment can reduce the toxicity problem.
  7. Frequent Laundry can reduce light and rubbing fastness.
  8. The application of pigments is easy and this pigments price is less than others.
  9. Pigment doesn’t make a bond with fiber or fabric.
  10. Pigment is not able to gives is the exact color.
  11. Pigment doesn’t recommended expensive machine to do this process.

Classification & description with trade name of Mordant dyes and methods of mordant dyeing.

Mordant is a word which is related with hydrophobic fiber dyeing is come from a Latin word mrdaeo means some material which is Strongly cling with something’s. Mordant is essential equipments which are used to make mordant dying to attach with fiber so hardly. An organic compound named tannic acid can be listed with mordant. Now a day the material is used so much with mordant dyeing is called chromium. So that mordant dyes also called chrome dye. This type of dyes is specially good for synthetic fiber.

 

Mordant dyes react with metal oxide and make insoluble pigment. The ancient time so many dyes source are come from vegetable like madder, log wood, fustic etc. the other hand so many dyes come from some moth like cochineal, kerness, lakha etc.

 

Mordant Color
Aluminum Oxide Red
Tin Oxide Pink
Iron Oxide Brown
Chromium Oxide Puce Brown
Copper Oxide Yellowish Brown

 

Classify of the mordant dye

Nirto dyes

Definitions of Different types of fabric’s lay & packages.

Accessories, Fabric, Fashion, Garments, Machinery

Let’s have a discuss about Definitions of Different types of fabric’s lay & packages.

Tow type of lay according to primary method.

 

Different types of fabrics lay & package .

Different types of fabrics lay & package .

  • According to structure of fabric

            Straight lay

This type of lay are spread the spreading measurement by the full length of marker

           

           Stepped lay

These types of fabrics are spread without follow full length of marker. As a result these types of fabrics lay are spread of step by step. Because of being step by step using of that marker is different type of marker. Too many fabrics are west to make garment by using this technique and it’s a little critical to use, so day by day it’s loosing its popularity.

 

  • According to fabric spreading way

            Spreading lay from right to left

This technique is suitable for high length and open fabric. Every time of after spreading this technique are required to cut the fabric and start spreading from where it was cute. This is the reason every time these spreading machines start spreading from starting place.

           

            Spreading lay from left to right.

The working technique of spreading lay from left to right is as same as right from left. Different is this technique are required to turn over the fabric lay after complete the spreading.

 

            Zigzag lay

This methods are start the spreading from a starting point and go to the end point of spreading and its come back to the starting point without cut the fabric. Today this kind of techniques is so much popular spreading technique around the world but is methods can make the problem for asymmetric fabric.

 

 

 

  • According to the package of fabric.

 

             Open fabric roll

Open fabric roll is most popular fabric packaging method from all of fabric packaging methods. Without any fold this technique can methods can package more than 100 miters cloth which width can be 75 cm to 3 miters. To hand spreading and machine spreading is able to spread this roll.

 

             Tubular fabric roll

Most of the knitted fabric are packaging by folded fabric roll. Basically the tubular knit fabric roll is making by the width measurement of t-shirt or sports cloth. Spreading machine is need to spreading this fabric.

 

             Folded fabric roll

The middle point the fabrics are fold and packaging by a board which is perfect to retail business. These types of fabric package are not useable in garments because machine spreading is not possible to do. So this method is limited usage in present.

 

           Folder fabric scuttled

This technique is suitable for check and knitted fabric. To make this fabric takes a little more carefulness to make sure this fabric without any invalid fold but this package are make by the kink of the edge of fabric. Spreading of this fabric is so much hard so machine spreading is so much important for this method.

 

          Hanging fabric package.

Most valuable and expensive fabric is package by hanging fabric package like velvet fabric. This method makes sure the fabric is hanging in a frame to keep it without any crease. This packages fabric is spreading by labor. It’s not able to spread by machine

Discussions of the methods of fabric spreading

 

Fabric spreading is so much important part of a garments industry to cut the fabric and sewing properly and proper shape. After spread the fabric, it’s ready to cut and make them desire look. Without spreading fabric not possible cut so many pieces of cloth at a time which way is important in garments industry.

 

Basically most of the fabric are import in garments industry in a few different package and roll shape. Those fabric roll and package are unpacking by spreading on the cutting table like lay and make it ply one by one.

 

Two types of methods to makes lay by spreading fabrics.

 

  • Manual methods
    • Fully Hand spreading this method is working by two people who are working from two different side of spreading table by hand or spreading fabric on the table by crossing a rod in to the tube in the center of roll of fabric. This spreading process a little slow and not so much finished and quality full.
    • Hand spreading with hook.This method also a part of manual process called hand process with hook because this process is a little different from hand process with a little extra material called hook. Which is made from iron and this tool looks like an English alphabet “J”. This method has a little advantage than hand process.
    • Hand spreading with spreading track
      Spreading track is a special tool for hand process. Tracks carry the roll of fabric and spread on the spreading table by changing this position from front to the end of the spreading table. This method is working by two people who are working from two different side of spreading table by handling the track tools and spread the fabric on the table. The basic three condition of making a lay of fabric are not include in following manual methods.
  • Mechanical methods
    • Semi Automatic spreading
      Semi automatic machine is working almost similar to Hand process with spreading track process because this methods working technique and working prouder are same but this process are working by electric motor. A roll of fabric are installed in the machine like Hand process with spreading track and this roll are spreading on spreading table automatically. The spreading machine are running on the spreading table by from one side too another side by electrical and mechanical power.The advantage of semi automatic machine

      • The machine has the ability automatically count the ply of fabric.
      • After cut the fabric the machine has the ability to catch the edge of fabric.
      • This machine has a special tool called inspection light which is check ant kind of fault in fabric.
      • To salvage alignment this machine has a photoelectric guide.
      • The machine has the ability automatically cut the ply of fabric.
      • The opening up of fabric from roll is positive & there is a regulator to adjustment the spreading and opening up fabric speed.
      • The facility to maintain the tension of fabric is including in this machine.
      • To make the surface plain has a toll are called leveling blade.
      • A platform is installed with the head of the machine for operator to seat and operate the machine.
      • This machine can spread three miter of fabric and this machine can carry from 80 KGs to 675 KGs.
      • This machine can spread 100 miter fabrics per minute.
      • 25 CM lay can be makes by this machine.
    • Fully Automatic spreading
      Fully automatic machine is upgrade version of Semi Automatic. This machine has the all of quality which is included in Semi Automatic. Full automatic machine has some special feature are makes it more special. Fully automatic machine is maintained by robot and micro processors.The additional advantage of fully automatic machine are given blew.

      • This machine can be directed or fixes how many ply have to spread before start spreading.
      • This machine is working by robotic technique so if the fabric roll gone empty then this machine get another new roll automatically without any human power and start again spread where it was ended.
      • There is a sensor in front of head. This sensor marks the fault area of any fabric and automatically cut the fabric width and stat again spreading.
      • Every type of fabric is able to spread and its can makes every type of lay.
      • This is automatic spreading machine so its can work so many faster then others spreading methods.
