Garments || Flow Chat of Apparel Manufacturing

Garments are the final achievement of textile processing, which started from fiber as a raw material of finished goods. After completing spinning, weaving, wet processing; the materials are ready for apparel manufacturing. Apparel is made generally from dyed or printed fabrics. The process of making a garment according to the pattern, desired design and style is called garment manufacturing.

Garments are produced in a line of sequence, which is either manually controlled or computerized. Anyhow, the sequence of a garment manufacturing is as follows:

Design/ Sketch

Pattern Design

Sample Making

Production Pattern

Grading

Marker Making

Fabric Spreading

Fabric Cutting

Sorting/ Bundling

Sewing / Assembling

Pressing/ Finishing

Final Inspection

Packaging

Dispatch to Buyer or Retailer

Now a days the sequence of manufacturing a apparel is controlled by modern technology. Different types of software is used in garments industry. A huge investigation is needed in the every steps of processing.

Anyhow, garments industry has a bright future.

Flow Chat of Jute Products Manufacturing || Spinning To Finishing

Jute fiber is a natural bast fiber. It is harder than other textile fibers. Its spinning process is different from others spinning.

Jute is a natural fiber. It is environment friendly. Due to its worldwide demand different country manufacture jute goods. Jute goods produce by a line of sequence. Its manufacturing process is completely different from cotton. By the following way jute goods are produced:

Selection of jute for a batch

                                  ↓ (According to jute grade)

Piecing up

Softening or Lubricating

                                            ↓ (Application of emulsion on jute)

Batching

                                         ↓ (Piling of jute for certain time)

Breaker Card

                                             ↓ (Inter Card is used between this two)

Finisher Card

                                       ↓ (It may be half or full circular)

First Drawing Frame

Second Drawing Frame

Third or Finisher Drawing Frame

Roving

                   ↓ (For fine yarn)

Spinning Frame

                                 ↓ (Apron draft or Slip draft)

Winding

                                   ↓ (Roll winding & Cop winding)

Beaming

                                ↓ (For warp yarn of cloth)

Weaving

                                          ↓ (Insertion of warp & weft yarn)

Damping

Calendaring

Cutting

Folding

Sewing

Baling

Export

 

This is the common flow chart. Some additional steps can be added with it by depending on buyer requirement. It can be changed with respect to count of yarn but it is the principle of jute goods manufacturing process. It also depends on type of product like that CBC, Hessian or Sacking. We know that CBC is produced by fine yarn, Hessian is also produced by fine yarn but this yarn is slightly courser than CBC and Sacking is produced by courser yarn than previous two.

Any how our main object is to produce quality product. So we should research to improve the process.

Process Flow Chart of Dyeing Textile Materials | Basic Structure of Wet Processing Technology

Wet processing technology and its uses are huge in textile sector. Dyeing process for different textile materials could be different but its basic idea is same for all. For all types of dyeing pre-treatment is must for removing unwanted materials from textile materials. Pre-treatment style differs for the shade of dyed materials. Shade may be light or deep. Also these pre-treatment depends on buyer’s requirement. After pre-treatment textile materials are ready for dyeing. After dyeing after-treatment is necessary for get the final finished products. At last, that’s product becomes ready to use. This sequence can be expressed by a flow chart.

Basic Flow chart of dyeing textile materials is like the followings:

Grey Textile Materials (Fiber, Yarn or fabric)

Singeing

Desizing

Scouring

Bleaching

Mercerizing

DYEING/PRINTING

Finishing

Marketing

Now I like to discuss shortly about the different terms of the flow chat. Here, grey textile materials are fiber, yarn or fabric which is also consider as the raw materials for dyeing.

Singeing is the first steps of pre-treatment. The process by which loose, hairy and projecting fibers are removed is called Singeing.

Desizing is the second steps of pre-treatment. By this process gummy materials are removed. Also size materials removed by this process.

Scouring is the third steps of pre-treatment. This process is performed for removing impurities of the textile materials.

Bleaching is another important step which is used to reduce natural color of the raw materials. Dyeing performance depends on it much more.

Mercerizing is the special types of treatment. It performs if buyer wants. It is an additional treatment. It increases the strength and luster of the materials.

Dyeing is the main process where a white material becomes decorated by different colors. We have to know about the depth of shade of the materials.

Printing is called as localized dyeing. Different types of printing are done for giving special appearance on colored or white fabric.

Finishing is the last treatment of wet processing. Different types of properties can be added to the materials by different finishing effects.

Marketing is our main goal. Say, if we done everything but there have no buyer then everything is waste. So we should have a strong marketing department.

So, all of this is about flow chart of Dyeing.
