What Is the Process of Developing a New Clothing Sample?

Custom and Proprietary Testing of Fabric 

The development of all clothing samples starts with fabric and a proprietary process for the development of yarn. In the case of knitwear which is the majority of apparel products in the market, development of yarn has to be done with consideration to the wearability and season of the yarn. All fabrics have to be compliant with the JIS which is Japan's authoritative and regulatory standard for industrial fabrics and their performance with regard to such issues as shrinkage and abraded fabrics. For the the the  Third party inspection from Japan dealing with the JIS will help in reducing the the quality of fabrics to the the lowest level. Japanese quality is a high quality market and  fabric is the base material of  the highest  quality level. Japan is a country of high and strict quality level of the fabric. This is the foundation of the highest quality level and the highest quality level offers the highest level.

Design Planning and Craft Confirmation

Following fabric selection comes design planning, where fashion trends and practical requirements come together. Designers must create styles that complement different knitted or woven fabrics, while also detailing specific elements, like stitch density for knit fabrics or seam allowances for woven fabrics. In the design of POLOs and casual pants, which are widely sold in Japan, the design must prioritize minimalist aesthetics that is versatile for different body types. The craft team then preps an internal blueprint for production, which outlines the methods of printing and/or embroidering, and checks the ‘how’ of each step to close any design vs production gaps. This step calls for focused collaboration across the design and technical teams to ensure the sample is both visually appealing and design viable.

Sample Patterns and Prototype Construction

Sample development hinges upon pattern making, which specifies the fit and shape of the finished sample. Expert pattern makers will develop sample patterns from the design sketches and leave the necessary allowances for future modifications. This is particularly important for knitwear since lots of elasticity and shrinkage of the fabric are critical in pattern making. The next step is to construct the prototype using a test fabric. This is where the elements of size, fit, and workmanship details are evaluated. When developing samples in small batches, the pattern making stage must also account for the future potential of mass production so that the sample can be readily adapted to mass production practices. Substantial modifications are made at this stage. For instance, the waist size of a pair of casual trousers may be changed, or the neck opening of a polo shirt may be adjusted tighter.

Craft Processing and Detail Optimization

Once the first sample is created, it then goes to the craft processing and detail optimization step. It is the most important step for showing the quality of the product. This step has many kinds of secondary processing methods and techniques. This can include vintage washing, enzyme washing, and stone washing which are all used for fabric of different characteristics. This step can also include embroidery and printing which can change the appearance of the product. It is important for all of these steps to be controlled according to the requirements of the craft. As an example, for the washing process, the temperature and the time must be thorough so the fabric is not ruined. There must also be a way to control the embroidery so that the pattern is not too loose and is uniform. For winter clothing products such as cotton padded coats, the filling process and sewing density are also optimized so that the clothes can retain and improve the warmth. All the changes that are made are based on the fabric and the design requirements, to improve the sample to better fit the needs of the market.

Third Party Inspection and Sample Finalization  

Before finalizing any samples especially for the Japanese market, quality inspections are a must. A Japanese third-party inspector will check the sample for size accuracy, quality of the fabric, craft details, washing fastness, and other things. Unqualified items will be re-optimized for things like fabric shrinkage, and the pattern will be re-made for size deviations. Only samples that have passed all the inspection items can be finalized. While this process can seem tedious, it is what helps the sample to meet the quality standards of the Japanese market. Doing this will help to minimize rejection in future export steps.

Landing and Mass Production Conversion

The last step in the development of a sample is integration of the sample with the mass production process. This step signifies the commercial worth in the entire sample development process. The finalized samples, together with the complete technical pack containing production specifications, craft guides, fabric types, and inspection criteria, lay the groundwork for mass production. For small to medium batch orders, the production line can adjust to the sample specifications and track production in real-time.  The integrated service from fabric development through sample development and exporting enables seamless transition from sample to mass production, reduces time to market, and allows brands to capitalize on opportunities.
