About Ring spinning frame:

Spinning is the final step of yearn manufacturing process. The working procedure of ring spinning frame is taking the roving comes from simplex and produced yarn by reducing the weight of unit length. Ring is attached around bobbin. The traveler rolling on ring and enfold the yarn on bobbin. Ring spinning frame plays the vital role to spinning the yarn so it is called Ring spinning frame. Ring spinning frame’s production system is conventional.

Ring frame is only one machine which can produce yarn by any kind of fiber. Basically the working system of ring spinning frame is easy and the cost of machine is a little cheap. It is easy to separate the bobbin from ring and easy to carry. but a few problem also reduce its popularity like, working speed, conventional system, large amount of electricity consumption.  please follow the link to know more about rotor spinning frame and ring spinning frame.

Describe of singeing machine

Singeing Machine - Textile Student

Singeing is the process of applying a protective adhesive coating on the surface of the warp yarn so as to increase smoothness, luster, evenness, weight and strength of the yarn. This process is very important to increase the efficiency of weaving.

Singeing Machine – Textile Student

On the other hand this is a mechanical process where the warp yarn is beaming by electrical or hand process, that time one type of adhesive liquid coating on yarn. The coating sticks the projecting fiber on the land of yarn so that it’s being smoother, luster, evenness etc. This process is called singeing process or dressing. Statistic says after singeing! The yarn gets more than 15-20% stronger than ever. After singeing yarn get strength go fight against the rubbing which is created from ride in loom.

 

 

State the objects of singeing

  1. After make the coating on the yarn so that the project fiber adhesive with yarn so that it’s look smooth and get little more strength.
  2. After singeing the yarn get the strength to protest the rubbing when the weaving or knitting.
  3. Singeing increase the yarn’s diametrical length so the yarn get zigzag free smoothness.
  4. Singeing makes the yarn increase its weights.
  5. Singeing can change the grade of yarn from low grade to high grade
  6. The yarn can be used perfectly after singeing.

 

 

Generally singeing machine classify in four divisions for there drying methods.

Cylinder drying

            Two cylinder type

            Multi cylinder drying

Hot air drying

Infrared drying

Combined system

Singeing system classification is given blew.

Slasher singeing

Hot pressure singeing

High pressure singeing

Foam singeing

Electrostatic singeing

Polymer emulsion singeing

Combined singeing

Singeing less yarn makes various problem during weaving so singeing less yarn can’t perform as same as singeing yarn. Singeing makes a yarn perfect for weaving and for next process.

Description of tailoring

 

Tailoring is a process of garment making by take the measurement of one selected person’s body shape. One this garments making system the selected person select his/her favorite design, color, fabric. The garments all of measurement and every design can be depend on the customer. Tailoring system makes a garment for one single person.

 

One the other hand the garments industry system makes thousand of dress by three different size by taking baby, man and women body’s ideal shape and measurement. Garments system make pattern using marker and cut thousand of pieces of garments piece at a time and make them full useable garment after sewing and finishing. Garments and tailoring is same state of garments manufacturing system but in reality it’s two different way to make garment.

 

Tailoring is a small business but garment is a business with a vast word. Tailoring business is run by one administration and a few tailors are work to give the production. In a tailoring shop a cutting master is required to take the measurement from the customer’s (selected person who want to make a garment by his/her own body shape) different part of body and cut the fabric, send them to tailor to sewing, make a desire dress to look them perfect.

 

Ironing or calendaring is required to give the perfect satisfaction to the customer after complete the dress. Some time the cutting master also does the job as a tailor. Tailoring system has own style like one tailor only sewing one type of dress, if the tailor sewing pant than tailor must sewing pant not shirt. A shirt is takes a little long to complete in tailoring system than garment industrial system.

 

Without those information there is something to mention.

  1. For one selected person is make one selected dress.
  2. Not need to grade anything.
  3. One sewing machine is able to make a garment.
  4. The making cost of dress is more than the garments industry’s system.
  5. Feting of the dress are more than the garments industry’s system.
  6. Fabric wastage is much more than the garments industry’s system.
  7. Selected person’s own measurement is required to make a cloth so no need to use pattern.
  8. No need to use any cutting machine in tailoring.
  9. Trail option helps the customer to fit their cloth by wearing that.
  10. Never use care code in tailoring.
  11. After get the trail if the dress is not fit with the body, then there is an option to make it more comfortable as the customer required.
  12. Tailor gives the customer priority first so they keep trying till get the customer satisfaction.

Discussion about different type of splice

 

During the fabric spreading process, if the fault detector machine gets any fault or damage on the fabric then the fabric must be cut by width and start spreading from the edge of fabric already spread by overlapping. This kind of overlapping is called splice. Generally overlapping or splice is signed in marker.

Discussion about different type of splice

though this article suppose to describe different type of splice but in the reality there are two different type of splice according to the garments industry. splice is a technique which is help spreading fabric on the spreading table for the it perfect shape as it can sewing and get the desire garments product.

 

Two types of splice

Straight line splice

Straight line splice is pointed width with a straight line on the spreading table to show the fabric edge. Pattern is stick with both side of straight line into marker. Fabric spreading is starting with 2 inch of fabric extra on splice line positions.

 

Interlock splice

This kind of splice is hang two straight line with is add into a specific point. At first this marker design is draw on the marker table by chalk. Interlock splice is defined two interlock pattern in the two different lines. As like as the straight splice this splice also take extra 2 inch fabric on overlapping position.

Properties of pigments

  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.
  12. After printing or dyeing, drying or curing is important to fix the color on the fabric and fiber.
  13. Pigment is appropriate for every kind of fiber or fabrics.

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.
