It is very important to judge the composition of clothing fabrics. Here are some commonly used fabric composition analysis techniques:
1. Visual inspection: First, through observation The appearance and texture of the fabric can initially determine its composition. For example: cotton fabrics usually have a natural and soft texture, silk fabrics are smooth and shiny, and linen fabrics have obvious twist patterns.
2. Hand feel judgment: The hand feel of different fabrics is different. You can tell the composition of a fabric by feeling it. For example: cotton fabric will give people a soft and comfortable feeling, while silk fabric will have a smooth and smooth feel.
3. Burning test: This is a commonly used method to determine the composition of fabrics. A small sample is ignited and the composition of the fabric is judged by observing its behavior during combustion and the characteristics of the residue. For example: pure cotton will form ash after burning, while synthetic fibers may emit black smoke after burning, and there will be a hard residue after burning.
4. Chemical reagent testing: This method requires the use of some chemical reagents to determine the composition of the fabric. For example: acid-base reagents can determine whether the fabric is pure cotton, acetate fiber or polyester fiber; dyeing reagents can determine whether the fabric is easy to dye (such as cotton fabrics are usually easy to dye), etc.
5. Peer communication: If you are not sure about the composition of the fabric, you can consult relevant practitioners, such as fabric suppliers, clothing designers, etc., they may be able to Judgments are based on experience and expertise.
It should be noted that the above methods are only preliminary techniques for judging the composition of fabrics. For some complex blended fabrics, more professional equipment and testing may be required. Perform accurate ingredient analysis.
