1. What is gram weight?
Gram weight is generally used to indicate the thickness of fabric. The greater the gram weight, the thicker the clothes. The weight of T-shirts is generally between 160 grams and 220 grams. If it is too thin, it will be very see-through, and if it is too thick, it will be stuffy. Generally, the weight of T-shirts is between 180 and 280 grams. (Short-sleeved T-shirts are generally made of 180-220 grams, which is just the right thickness to wear. Long-sleeved T-shirts generally use 260 grams of fabric, which is a thickened type)
2. What is the count?
Definition: The common weight is the number of lengths of cotton yarn weighing one pound.
Coarse count yarn: pure cotton yarn with a count of 18 and below, mainly used for weaving thick fabrics or pile and loop cotton fabrics.
Medium count yarn: 19-29 count pure cotton yarn. Mainly used for knitted garments with general requirements.
Fine count yarn: 30-60 count pure cotton yarn. Mainly used for high-grade knitted cotton fabrics.
The higher the thread count, the softer it is. T-shirts are generally 21 and 32 threads.
3. What is combing?
T-shirt cotton yarn can be divided into carded and combed yarn.
Carded yarn: refers to yarn spun by carded spinning process, also called uncombed yarn.
Combed yarn: refers to yarn produced by using high-quality cotton fiber as raw material and adding a combing process during spinning compared with carded yarn. The surface of the fabric is relatively neat and feels soft.
4. What are the techniques for 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 production, printing, printing and drying. The advantages of screen printing are high color fastness, durability and washability. Screen printing plate making is more expensive, so mass production is required to reduce costs, and it cannot meet the needs of single-piece or very small batch printing.
Transfer printing: also called heat transfer. 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 singeing treatment?
The characteristic of singeing 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 color of the fabric is uniform, and it can print clear and fine images. pattern.
6. What are the advantages of pure cotton fabrics? Why add spandex?
Pure cotton fabric is characterized by good hand feel, comfortable wearing and environmental protection, but it wrinkles easily. Adding a small amount of spandex yarn can significantly improve the physical properties of the fabric and greatly increase the elasticity of the fabric, while maintaining the texture and comfort of pure cotton. In addition, adding spandex to the collar can prevent the collar from becoming loose and deformed, and maintain the lasting elasticity of the collar.
How many types of T-shirt fabrics are there?
1． Ordinary pure cotton fabrics
Casual T-shirts are mostly made of ordinary pure cotton fabrics. T-shirts made of this kind of fabric are comfortable to wear, but slightly less stiff. It wrinkles easily and is easily deformed after being put into water.
2． Mercerized cotton fabric
Mercerized cotton fabric uses cotton as raw material, which is made into high-woven yarn through worsted spinning, and then goes through special processing procedures such as singeing and mercerization to make high-quality mercerized fabric that is smooth, bright, soft and anti-wrinkle. yarn. The high-quality knitted fabrics made from this raw material not only fully retain the excellent natural characteristics of raw cotton, but also have a silky luster. The fabrics are soft to the touch, moisture-absorbent and breathable, and have good elasticity and drape. In addition, they are rich in colors and are comfortable to wear. And casualness fully reflects the wearer’s temperament and taste.
3. Pure cotton double mercerized fabric
Pure cotton double mercerized fabric is a pure cotton product of “double burned double yarn”. It uses mercerized yarn that has been singed and mercerized as raw material, and uses CAD computer-aided design system And the CAM computer-aided production system can quickly weave the designed pattern fabric. After the gray fabric is singed and mercerized again, and a series of finishing operations are performed, this high-grade knitted fabric is produced. Its surface texture is clear and the pattern is novel. It has bright luster and smooth feel, which is better than mercerized cotton, but it needs to be mercerized twice, so the price is slightly more expensive.
4. Ultra-high count pure cotton fabric
This kind of fabric is rarely used by companies because it is very expensive. The price of pure cotton T-shirt fabric with 120 yarn count is as high as 170 yuan per kilogram, while the price of 200 yarn count pure cotton T-shirt fabric The price of pure cotton T-shirt fabric is even higher, reaching more than 3,000 per kilogram, while the pure cotton T-shirt fabric with a yarn count of 250 costs 1,800 pounds, and our country does not yet have the technology to produce this kind of fabric. Commonly used fabrics used in the production of T-shirts and cultural shirts include: pure cotton jersey, polyester-cotton single and double-sided, pure cotton, polyester-cotton hexagonal, square mesh, herringbone, composite rib, striped mesh, etc. Not easy to deform, but the wearing comfort is slightly worse than pure cotton.
The characteristics of common polyester-cotton fabrics: soft and thick feel, not easy to deform after washing, but the wearing comfort is slightly worse than pure cotton. Common polyester-cotton ratios are 80% cotton, 20% polyester or 65% cotton, 35% polyester. Characteristics of pure cotton fabrics: good feel, comfortable to wear and environmentally friendly. The weight is generally between 160 grams and 300 grams. If it is too thin, it will be very transparent, and if it is too thick, it will be stuffy. Generally, the weight of 180-260 grams is better, and the count Generally, they are 21 and 32, which refers to the average length of cotton fiber. The higher the number, the softer it is. The veil is divided into plain yarn, semi-fine yarn and fine yarn. The surface of the plain yarn fabric will be rough, especially in dark colors. The fabric will have white yarn spots. The surface of fine yarn fabric is relatively neat and feels very soft
