Technical specification of modern ring frame

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.

Types of wet processing

Wet Processing
Types of wet processing

Wet processing obeys an important duty to do in textile industry. Wet processing classified in three divisions in a short description. Because there are multiple divisions on those points are given below.

Types of wet processing

  1. Pr-treatment

Pr-treatment means preparation process. Before taking any necessary and important process like dying on a fiber or yarn has to do some preparation process called per-treatment. Pr-treatment makes the material as it can color as much as easy way. Basically this process used acid, salt, oxidizing agent, reducing agent, enzyme, wetting agents and many more. Selection of wet processing elements and temperature are decided by expert engineers according to the machinery are used in dying or wet processing floor.

 

  1. Dyeing and printing
    • Dying

Dying is a process where fiber, yarn or fabrics are colored by water and dyestuff is called dyeing. All this dying process done by penetration technique as it can spread all over the surface of the raw material. The dye can be different and change by the properties and category of that fabric is used to. The application of dyeing is depend on hue, tone, brilliancy, fastness, affinity, solubility and many more properties. Dye is a colored material which is built by chromophore and auxochrome group.

Basically we get some dyestuff in market.

  • Direct Dyes
  • Basic Dyes
  • Acid Dyes
  • Sulpher Dyes
  • Reactive Dyes
  • Vat Dyes
  • Azoic Dyes
  • Disperse Dye

 

    • Printing

Printing technique let us create custom design with different color on a fabrics land. In a single word “Printing means make a design with different color and shape on a fabric as it mention some think as people can accept it”. There are few printing technique are used to complete printing process. Following style are given below.

  • Direct Style
  • Dyed Style
  • Resist Style
  • Discharge Style
  1. Finishing

After complete bleaching dying and printing one step is left to get the final product that is finishing. Generally the type and quality of finishing is depends on buyer, customer or present market status. Actually the aim of finishing is increasing the fineness and comfort ability. Sometime finishing also depend on the purpose of the fabric are used to.

Generally two ways to finishing the fabric

  • Mechanical Finishing

Calendaring, Sanforization, Embossing, is the example of mechanical finishing.

  • Chemical Finishing

Merchandising, water proofing, fire proofing, is the example of chemical finishing.

Measurement of a Shirt

Fashion, Garments
Measurement of a Shirt

Shirt is a maximum globally used cloth and this is especially designed for men but women also used shirt for office and many purpose. There are too many parts require to measure and cut and sewing by industrial or tailoring technique. Shirt should be fitting by different body size otherwise those dresses couldn’t able to get its desire look. Tailoring technique makes perfect shapes and design as customer required but this is a little expensive than industrial system. In that tailoring system one shirt needs a longer time and makes wastage than industrial system. Industrial system takes so much less time than tailoring and industrial system makes less wastage but both has there own specialty.

Measurement of a Shirt

Measurement of a Shirt

You can find distinguish between garments and tailoring process. Here is some measurement that’s need to measure with a little careful to make a perfect shirt for customer as required. Prefect measurement could take a place of customer satisfactions. A textile engineer or a tailor cutting master should have the knowledge about this point are given blew to obey there professional duties.

5+6      = Collar Point

7+8      = Collar Height

9+10    = Collar Length

8+11    = Band Width

5+14    = Collar Outer

6+15    = Collar Inner

12+13  = Collar Spread

16+17  = Chest/Bust

18/19   = Waist

20+21  = Bottom/Sweep

35+36  = Pocket height

22+23  = Across Chest

17+24  = Arm hole

24+26  = Sleeve length

26+27  = Cuff length

28+29  = Front length

31        = Box plate/Top center

24+25  = Back yoke

32+33  = Elbow

17+21  = Side Seam

30+34  = pocket length

24+28  = Shoulder

All those measurement are required to make a shirt what ever it in garments or tailoring system. Though this is the measurement area but there is little way to take perfect measurement by expert cutting muster. Please take an expert advice to take first step in this measurement area.
