Necessity · Specification – ITI Sewing Technology
This chapter explains two important concepts in garment construction: necessity and specification. These terms are widely used in tailoring and garment industries to ensure proper planning, accuracy, and quality in garment production. Understanding necessity and specification helps students create garments according to required standards and customer expectations.
What is Necessity?
Necessity refers to the essential requirements that must be fulfilled during garment construction. It includes all the basic needs such as correct measurements, proper fabric selection, suitable tools, and accurate stitching methods. Without fulfilling these necessities, it is difficult to produce a good quality garment.
Importance of Necessity in Garment Making
- Ensures proper planning before starting work
- Helps in selecting the right materials and tools
- Reduces chances of errors
- Improves efficiency in production
- Leads to better quality garments
Examples of Necessity
- Taking accurate body measurements
- Selecting suitable fabric for the garment
- Using correct tools and equipment
- Following proper stitching techniques
- Maintaining cleanliness and safety
What is Specification?
Specification refers to detailed instructions and requirements related to a garment. It includes information about size, design, fabric type, stitching details, finishing, and measurements. Specifications act as a guide for making garments exactly as required.
Importance of Specification
- Provides clear instructions for garment construction
- Ensures uniformity in production
- Helps in maintaining quality standards
- Reduces confusion and mistakes
- Improves communication between tailor and customer
Types of Specifications
1. Measurement Specification
Includes detailed body measurements such as chest, waist, hip, shoulder, and length.
2. Design Specification
Includes style details such as neckline, sleeves, collars, pockets, and overall design.
3. Fabric Specification
Specifies the type, color, texture, and quality of fabric to be used.
4. Stitching Specification
Includes type of stitches, seam allowance, and finishing methods.
5. Finishing Specification
Includes pressing, trimming, and final finishing details.
Difference Between Necessity and Specification
| Necessity | Specification |
|---|---|
| Basic requirements for garment making | Detailed instructions and guidelines |
| Focuses on what is needed | Focuses on how it should be done |
| General in nature | Specific and detailed |
Application in ITI Sewing Technology
In ITI training, students learn to identify necessities and follow specifications while making garments. They are trained to take accurate measurements, understand design requirements, and follow instructions carefully. This helps them produce garments that meet industry standards and customer expectations.
Precautions
- Do not ignore basic requirements
- Follow specifications carefully
- Double-check measurements and instructions
- Use proper tools and materials
Conclusion
Necessity and specification are essential concepts in sewing technology. Necessity ensures that all basic requirements are fulfilled, while specification provides detailed guidance for garment construction. Together, they help in producing high-quality garments with accuracy and efficiency. For ITI students, understanding these concepts is important for becoming skilled professionals in the garment industry.
