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.

Carding-Machine-Photo-TextileStudent.com

This article is about What is carding and classification of carding machine? Trash and impurities full fiber is not able to proper spinning to build the basic construction of yearn. So it’s should be remove by different process, which is include in blow-room one process after another process. Removing Trash is process is started from first line of blow room and the second step of Trash removing process are called carding process. Carding process is one of them, which are played the vital role to remove maximum of trash from fiber. To make yearn it’s important to make a sliver after removing trash.

The basic fundamental of carding machine is removing trash and make long sliver to build the basic construction of spinning yearn.

 

 

Objects of carding machine

  • Take the lap from blow room and make it small unit and make them align.
  • After blow room process, make sure the fiber is full free of dust, short fiber, break seed and unnecessary things.
  • Extra and unnecessary short and hairy fiber completely removed from sliver.
  • Made by the Immature fiber is called napes are make free by carding process.
  • Fiber could be blending and mixing if necessary by this process.
  • Make the fiber prepared for next process by make them equal and same distance among every fiber.

 

 

Different types of carding machine:

  • Roller and clearer card
  • Stationary flat card
  • Revolving flat card

 

 

 

In the era of modern science the carding machine also discovered new and easy to use by depend on setting and setup the cylinder and take in. Out modern carding machine gives us extra care about the fiber and make them more smooth and useable. The another different design and style carding machines are

  • Dual carding machine
  • Mono or single carding machine
  • Tandom carding machine

Fabric Cutting!

Fabric cutting is important in textile or garments industry. A garment will be ready to wear when it will be completed by sewing many part of fabric which are cutter in a cutting table in the lay or spread of fabric.

fabric cutting is important part of garments manufacturing process. quality full fabric cutting reduce the wastage of fabric and make the business profitable. Today’s business market “good quality product is the main fact, price is low and quality is high is the first requirement of all of buyer around the world”. so a good quality cutting operator is required to cut the fabric.

  • Thousand of piece of garment’s fabric should be cut one time on cutting table at a time.
  • It is possible to cut thousand of garment’s fabric same design which is provided from buyers or any company.
  • Too many lay/spread of fabric’s can be cut different size bye the tender of buyer.
  • Possible to cut fabric and make garments for different country and cultures.
  • Make this fabric suitable to use to next level, I point to the sewing section.

 

Requirements of fabric cutting:

  • Precession of cut
  • Clean of edge
  • Consistent cutting
  • Support of the lay
  • Infused edge

 

Methods of fabric cutting:

there are few to cut the fabric. the methods are chose by the operator by here own preferences. The methods are fabric cutting are given blew.

Definition and list of Sewing machine

 

By which machine used to sewing two or more pieces of fabric called sewing machine. A sewing machine sewing not only fabric, but also others material like bags, lather, foot-wear, tent & many more, Etc. sewing machine also used to increase the fabrics fineness and good looking by some special effect. Different sewing machine are obey there different duty to makes a better garments as we want.

 

List the type of sewing machine are used in textile industry

 

  • Manual operated sewing machine

Manual operated sewing machine is working by human hand or legs power. The machine operator’s have to operate the machine by his own hand or legs power so that operator can’t work so firstly and smoothly. As a result the manual operated sewing machine’s production is less than electrically operated sewing machine. Today most of the manual sewing machine used in home or a trailer shop because it’s not so expensive and it’s easy to maintenance and use.

 

 

  • Electrically operated sewing machine:

This kind of sewing machine working by electrical power, so it’s work first and smoothly. Comparatively electrical operated machine work and production so good than others so it’s called industrial sewing machine. Industrial sewing machine could be much type but some common types of machine are here.

 

  • Lock stitch machine
  • Chain stitch machine
  • Over lock machine
  • Zigzag stitch machine
  • Flat lock machine
  • Blind stitch machine
  • Button holing machine
  • Button attaching machine
  • Bartech machine

 

Industrial machine could have one to four needles as required so that many industrial sewing machines presented company fill the importance. There are too many industrial sewing machine produce company around the world but most of this machine used in Bangladesh like Juki, Pegasus, Seruba, brother, Puf, Singer Etc. Every company make competition together there machines power, speed, efficiency, performances etc. the maximum used machine in Bangladesh is juki.

 

Some machine’s has programming so that it’s possible to make automatic sewing for any design or length what ever you want but this machine is expensive and so hard to maintenance. Though its makes better than others but usages in our country is so less.

Importance of textile testing:

Testing is an essential step in textile sector for keep the quality according to buyer on the product. So, textile testing is so much important for textile study let’s have a discussion about Classification of Textile Testing. Without textile testing there is no way to make a place in largest marketplace where is contesting among every single company. To make better garments than textile testing is so important. Now a days every textile industry test there produced garments step by step from fiber selection to cloth, to be hundred percent sure as a better textile product. Any company’s fame depends on their product quality and the product quality depend on textile testing. So, we can call it the textile testing is a part and parcel in textile industry.

Textile testing:

Textile testing is a most important way to certify a textile fiber, yearn or fabric as a use able material in textile products or garments. Testing will inform you what kind of fiber is this and approximately what kind of garments you’ll be produce by this fiber, yearn, fabric. Let’s have a look basically how many textiles testing is used to test, textile fiber, yearn, fabric in the textile lab.

Classification Fiber Testing:

  • Identifications of fiber
  • Grading
  • Color of fibers
  • Fiber Length
  • Fiber strength and elongation
  • Fiber fineness
  • Fiber maturity
  • Trash
  • Neps
  • Short fiber index- SFI
  • Short fiber content- SFC
  • Immature fiber content
  • Dust

Classification Yearn Testing:

  • Yearn count.
  • Twist per unit length
  • Single yearn strength.
  • Lea strength and elongation
  • Appearance
  • Evenness and regularity
  • Hairiness

Classification Fabric Testing:

  • Strength and elongation
  • Length
  • Width
  • Thickness
  • Weight
  • Number of warps yearn per unit length.
  • Number of wefts yearn per unit length.
  • The count of yearn used.
  • Design and construction of cloth
  • Earn permeability.
  • Crimp
  • Shrinkage
  • Stiffness
  • Handle
  • Drape
  • Crease resistance and recovery
  • Abrasion
  • Thermal properties
  • Pilling
  • Water absorbance and resistance

In conclusion, textile testing plays a crucial role in ensuring the quality, safety, and performance of textiles and textile products. By subjecting fabrics and materials to various testing methods, manufacturers, retailers, and consumers can make informed decisions and maintain high standards in the textile industry.
