Detailed explanation of common T-shirt fabric knowledge

1. What is gram weight?
Gram weight is generally used to indicate the thickness of the fabric, the larger the gram, the thicker the clothes. The weight of T-shirts is generally between 160 grams and 220 grams, too thin will be very transparent, too thick will be stuffy, generally choose between 180-280 grams is better. (Short sleeves are generally 180-220 grams, this thickness is just right, long-sleeved T-shirts generally choose 260 grams of fabric, which is a thickened type)
2. What is the number of threads?
Definition: The length yardage of cotton yarn with a nominal weight of one pound.
Coarse count yarn: 18 counts and below pure cotton yarn, mainly used for weaving thick fabrics or fleece looping cotton fabrics.
Medium count yarn: 19-29 counts of pure cotton yarn. It is mainly used for knitted garments with general requirements.
Fine-count yarn: 30-60 counts of pure cotton yarn. It is mainly used for high-grade knitted cotton fabrics. The higher the thread count, the softer it is, and T-shirts are generally 21 and 32 threads.
3. What is combing?
T-shirt cotton yarn can be divided into plain combed yarn and combed yarn.
Combed yarn: refers to the yarn spun by the comb spinning process, also known as uncombed yarn.
Combed yarn: refers to the yarn produced by using high-quality cotton fiber as raw material and increasing the combing process compared to ordinary combed yarn when spun. The surface of the fabric is relatively neat and soft to the touch.
4. What are the processes of T-shirt printing?
T-shirt printing is basically divided into two types: screen printing and transfer printing.
Screen printing: The technology is relatively complex, mainly including design, film, plate drying, printing, drying. The advantages of screen printing are high color fastness, long-lasting and washable. Screen printing plate making costs are high, so mass production is required to reduce costs, and cannot meet the printing of single pieces or very small batches.
Transfer printing: also known as hot painting. The advantages are bright colors and simple technology. The disadvantage is that the pattern has poor durability, is not resistant to wear and tear, and is not resistant to washing.
5. What is burnt hair?
The characteristic of burning hair treatment is to remove the fuzz formed on the surface of the yarn due to unwound fibers and protruding fibers, making the fabric smoother and more beautiful, and the fabric color is uniform, and it can print clear and fine patterns.
6. What are the advantages of pure cotton fabrics? Why add spandex?
Cotton fabric is characterized by a good feel, comfortable and environmentally friendly, but prone to wrinkles. Adding a small amount of spandex yarn can significantly change the physical properties of the fabric, greatly increasing the elasticity of the fabric while maintaining the texture and comfort of pure cotton. In addition, the addition of spandex to the neckline can prevent the neckline from loosening and deforming and maintain the long-lasting elasticity of the neckline.
