The hot summer is about to enter. If you want to choose the most active item in summer, it is T-shirts.

T-shirts are very ordinary. There are no technical barriers, and there are many companies doing it. The price ranges from 4.9 yuan a piece to several thousand yuan a piece. It can be so low that you find it incredible, or it can be so high that it is incredible.
Are there any big differences between them? How to see it?
The production of all products starts from raw materials.
Almost all fiber materials can be used to weave T-shirts, including cotton, wool, silk, and linen , viscose, mercerized cotton, Tencel, polyester, nylon, etc. Of course, spandex fiber is essential in T-shirts, it can provide good elasticity.
Among these materials, polyester and nylon are relatively cheap, silk is more expensive, and cotton is the most common.
If the content of polyester or nylon in a T-shirt material exceeds 50%, unless it can be stated that polyester or nylon is The special thing about nylon is that if the price exceeds 100 yuan, it is definitely unreasonable.
Test report
“Xinjiang’s cotton output in 2020/2021 is 5.2 million tons, accounting for about 87% of domestic production and about 67% of domestic consumption.”
Almost all domestic T-shirts are made of Xinjiang cotton. Xinjiang cotton also has advantages and disadvantages, including not only long-staple cotton, but also upland cotton (fine-staple cotton). , Xinjiang long-staple cotton is the best. For the same count (an indicator of fineness, the higher the count, the finer the yarn), the price of long-staple cotton yarn is 1.3 times that of fine-staple cotton.
On some platforms, merchants emphasize that the raw material of T-shirts is Xinjiang cotton. This is actually a very common gimmick. We don’t need points for this.
Currently there are 21 cotton ring-spun yarns (long-staple cotton) The price of 1 share of high-quality products is about 29,000 yuan/ton, and the price of 32 pieces of 1 share of high-quality cotton ring-spun yarn (long-staple cotton) is about 31,000 yuan/ton.
Three kinds of cotton
Count is an important reason for the large difference in fabric prices.
Count
The count of ordinary T-shirts is concentrated between 20 count/double strand and 32 count/double strand, which is a low yarn count, and the intuitive feeling is that the difference is not big.
High-end T-shirts may use 60-count/double-strand-80-count/double-strand, high-end T-shirts The softness of the fabric is very strong, and the gloss of the fabric will also be improved.
Some high-end T-shirts also use low-count yarn to show the wideness of the T-shirt.
T-shirts use less cotton yarn with a count higher than 80 , this is because the fabric is too thin and has good skin-friendly properties. The phenomenon is that the T-shirt has high light transmittance, will show spots, and is close to the skin, so the comfort will be reduced.
Choosing T-shirts made of high-count fabrics (more than 60 count) means choosing a higher price. The general selling price will be more than 300 yuan. The surface of this kind of T-shirt will have an elegant glossy feel, which is different from the matte feel of T-shirts made of low-count fabrics. It also needs to be used when using it.Take good care of it, it is easy to deform, cannot be machine washed and dried, and can easily become a high-grade rag.
If you wear it for daily commuting, it is recommended to choose good quality, thicker and low-count fabrics. 20 pieces/double shares are easier to take care of, 50-100 yuan is enough.
80 pieces are a bit see-through and will show some spots
Gram weight (weight per square meter) can better reflect fabric differences and reflect fabric properties, especially thickness. The weight of general T-shirt fabric is 170-220g. The larger the gram weight, the thicker it is, and the smaller the gram weight, the thinner it is.
The weight of the fabric depends on the yarn count and the density (tightness) of the fabric. High-density fabrics generally have better stability, good shape retention, and thick hand feel, but will not affect the drape performance of the fabric.
If a piece of fabric feels thick and stiff, it means that the drape performance is not good and it is not soft enough. The quality is relatively poor. The reason may be that cotton with a short single fiber length is selected, or the fabric is not handled well enough during the finishing process. For example, the chemical reagents are not cleaned, or the high temperature setting temperature destroys the fabric fibers. original elasticity.
After all, softness is an important indicator of comfort.
Of course, there are many factors that affect the softness of fabrics. Poorer fabrics can become very soft if softened.
It is also very common for T-shirts to use brushed cotton fabrics.
brushed fabric
Earing uses the friction between a sanding machine and emery leather to pull and stand up the fibers on the surface of the fabric. This treatment will damage the strength of the fabric, but it also makes the fabric feel softer, richer in texture, and improves drape performance. Strong, this should be a positive treatment. After all, adding a post-finishing process also increases the cost.
If you like a smooth and cool feeling, don’t choose a brushed fabric T-shirt. If you like softness and Choose brushed fabric for texture.
Cotton is the most commonly used T-shirt raw material, but it also has shortcomings , such as easy to wrinkle, shrink, poor gloss, etc.
In order to improve these shortcomings, special cotton fabrics are available on the market.
Pure cotton T-shirts that have been mercerized (liquid ammonia process is most commonly used), making the cross-section of the fiber The shape has undergone a fundamental change, the waist-round cross-section has become circular, the gloss has been greatly increased, and the wrinkle and shrinkage properties have also been improved.

Mercerized T-shirt
Anti-wrinkle finishing can also improve the wrinkles and shrinkage of cotton T-shirts. Anti-wrinkle finishing often uses aldehydes. This is a relatively polluting and unhealthy process that uses chemical reagents. It will also make the plastic feel of cotton T-shirts sharply increase. It is generally not recommended.
Anti-wrinkle
Three-proof T-shirts, cool clothes Sensational T-shirts have been a hot marketing topic in recent years, and there is nothing new in technology. In the future, the editor will do a special issue of related technical analysis.
Three defenses
Mercerized finishing, anti-wrinkle finishing, three-proof finishing or cool finishing will not add much cost to the T-shirt fabric. In effect, the functions of three-proof finishing and cooling finishing often disappear after three or five washes. If It is also unreasonable to use these concepts to significantly increase product prices.
“Noble clothing and supplies should be made of pure natural materials ”, no need for excessive modification.
