Write at least 150 words.


Band 9 answer with hard vocabulary and explanation

The diagram illustrates multiple stages involved in the production of bamboo fabric. 

Overall, the process follows a clear, linear sequence that begins with growing and harvesting bamboo and concludes with the manufacture of garments such as shirts and socks.

Initially, bamboo plants are cultivated in spring and harvested in autumn. The harvested stalks are then cut into thin strips, which are mechanically crushed to form a soft, pulpy mixture. This pulp is filtered to separate the long cellulose fibres from the liquid residue. Afterwards, water and amine oxide are added to the extracted fibres to soften them and enhance their elasticity.

Once the fibres have been treated, they are spun into yarn to form continuous threads. These yarns are subsequently woven into fabric using looms. Finally, the finished fabric is converted into wearable clothing items. In summary, the entire production of bamboo fabric combines natural plant material with both mechanical and chemical processes to create eco-friendly textiles.

How to Write IELTS Writing Task 1 — Process Chart

 Step 1: Understand the process
Look carefully for the start and end points.
Count how many stages there are.
Identify if the process is natural (e.g., life cycle, photosynthesis) or manufactured (e.g., making coffee, paper, bamboo fabric).

 Step 2: Plan your answer
Divide the process into 2 logical groups (e.g., “preparation” and “production”).
Note the direction of arrows and materials used at each stage.

 Step 3: Write the introduction

Paraphrase the question:
Example: “The diagram illustrates the stages involved in producing fabric from bamboo plants.”

 Step 4: Write an overview
Summarize the general trend or outcome — no details yet.
Example: “Overall, the process consists of several stages, beginning with planting and harvesting bamboo and ending with the production of fabric for garments.”

 Step 5: Describe each stage (body paragraphs)
Write in present simple tense (“The bamboo is cut…”, “The pulp is filtered…”).
Use sequencing words: first, next, then, afterwards, finally.
Avoid bullet points or notes — write full sentences.
Keep your writing formal and neutral.

Step 6: Add key features/details
Include what materials or tools are used.
Explain transformation at each stage (e.g., “solid bamboo is converted into liquid pulp”).
