Whether the quality of the T-shirt is up to standard or even excellent, the fabric is undoubtedly the basis. It is difficult to feel high quality when using synthetic fibers such as polyester or nylon as raw materials. Therefore, it does not absorb sweat and has poor breathability, making it difficult to wear. Comfort is naturally low unless special modifications are made to the construction of these fabrics.
Some merchants have inlaid a highly thermally conductive metal alloy on the back of a nylon T-shirt, which has good wear resistance and elasticity. It also feels cooler when worn than a cotton T-shirt. A lot. The idea is good, but with low raw materials and simple craftsmanship, it can only be said to be a special T-shirt, not a high-quality T-shirt.
Cool T-shirt
To judge the quality of T-shirts, fabric is the basis and workmanship is the key.
Sewing
T-shirt is a very basic item, with no hardware such as zippers and buttons, and very few accessories. The garment pieces that have been planted on the bed only need to be completed using three sewing processes: flat sewing, stretch stitching, and overlock stitching.
Planting process
The workmanship quality of T-shirts is actually the processing factory’s product quality requirements.
How to judge the quality of workmanship?
It is very simple, it is the quality of the splicing, hemming and finishing of each piece of clothing, including shoulder seams, upper collar, upper sleeves and side seams, hem and cuffs, etc. .
Illustrated T-shirt
Good workmanship quality requirements, shoulder seams, upper collar, upper sleeves and side seams are all overlocked and need to be When it comes to the overlock sewing machine, the overlock stitches only need to be dense and neat; when it comes to the flat seam, interlock sewing machine for hem and cuffs, the stitches need to be dense and straight, with no floating threads.
Theoretically, this is a basic requirement for sewing work and is not difficult. In the final analysis, it still depends on the quality requirements of the processing factory for T-shirts.
From closing shoulder seams, upper sleeves and upper collar, binding strips, closing side seams, hem and cuff seams, these sewing processes only take 12-15 minutes. , skilled sewing workers can do it faster, but the difference is not big.
Generally, processing plants require sewing workers on piece basis or have reservation requirements. In order to keep up with the schedule or for different economic benefits, the same sewing worker will also make different sewing tasks. Same quality level.
Sewing workshop
The finishing after sewing is the final check of quality, including thread cutting, ironing, trimming, packaging, etc.
T-shirts of general quality are relatively careless in finishing. As long as they can afford the processing fee, they will pass.
High-end quality T-shirts tend to take more time and cost more in finishing.
Post-inspection
So, judging the processing quality only depends on the sewing level of the processing factory and the level of finishing requirements.
In terms of cost, the processing fee for a general quality T-shirt is only 7-8 yuan, and the processing fee for large quantities of goods is 4-6 yuan. The processing fee for good quality T-shirts will be Achieving 30-50 yuan.
To look at the workmanship quality of a T-shirt, first look at the collar.
Some T-shirts use ribbed collars, and some T-shirts use plain cloth collars, each with its own characteristics.
Neckline
This cloth collar and T-shirt are more integrated.
2*2 ribbed collar, wide ribs, rough collar, big difference with the fabric of the clothes itself, obvious collar, mostly used for coats;
1*1 ribbed collar, narrow ribs, delicate collar, mostly worn inside.
No matter which collar is used, there is no difference in quality.
Rib
The sewing of the collar can be divided into single needle, double needle and triple needle. It can be judged from the sewing stitches. .
Two books and three books
Merchants often use two books and three books to mislead consumers, thinking that two books and three books are Needles are more labor-intensive and high-end.
When using the same sewing thread, the more needles, the stronger the sewing thread will be, but it will not be labor-intensive. The sewing time of two needles and three needles is exactly the same.
It is the industry consensus to use two needles for knitted fabrics. We do not need to pay for two or three needles.
In addition, the sewing thread is related to whether the T-shirt is firm.��
At present, the world generally believes that the British Coats sewing thread is the best, and the price is about ten times that of ordinary sewing thread. A single-needle Coats thread will be stronger than an ordinary two-needle needle. It costs a few dollars more to use Coats thread for a T-shirt.
Using Coats thread as sewing thread for T-shirts means higher quality.
There are two main methods for upper collar, splicing and overlocking, as shown below.
Splicing and overlocking
The spliced collar maintains the elasticity of the original ribs and is easy to put on and take off. The ribs are required to have good elasticity. Collar 2 layers.
The collar made by the overlock sewing method consists of 5 layers (4 layers of ribs and 1 layer of body). It is characterized by thick, durable and not easy to deform after long-term use. The requirements for ribs It is lower, but has poor elasticity, is difficult to put on and take off, and has good shape retention.
No matter which method is used to tie the collar, the quality of the T-shirt will not be affected.
Quality T-shirts require the collar to have relatively good elasticity and not deform after repeated stretching.
The collar is deformed and the rib quality is poor
High-quality T-shirts often use binding strips (with original fabric) to tie the bottom of the collar and The seams at the bottom of the shoulders are all covered. The better the T-shirt, the less the seams and seams are exposed.
The bundling strips look neat
Using bundling strips can reduce lateral friction and increase the aesthetics. This is an essential practice for high-quality T-shirts. . At present, T-shirts priced around 100 yuan basically do this.
The stitch density is an indicator of T-shirt quality.
Stitch
The stitch density of quality T-shirts is more than 12 stitches/inch.
If the stitch density is too sparse (such as 8-9 stitches/inch), the sewing thread will easily float after being worn for a period of time. If there is a thread break, the entire sewing thread will be Will fall off easily. The same goes for the seam line. The denser the line, the higher the quality of the T-shirt.
The stitches are flat
Seam line
Generally speaking, the higher the stitch density and seam density, the higher the stitch density and seam density. The higher the quality of the shirt.
The above aspects involve design or equipment reasons, so the following quality problems are mainly due to the operation problems of the sewing workers.
Are the lengths of the front and back pieces the same?
The different lengths of the front and back pieces
The inconsistent length of the front and back pieces is a very important quality issue.
Are the cuffs and hem seams even and are there any wrinkles?
Uneven seams
Wrinkled hem
Are the threads cleaned?
Threads are not cleaned
Cloth seams and multi-threads are not cleaned, which basically belongs to the finishing work of clothing. The finishing work mainly includes thread cutting, thread checking, damage inspection, ironing, etc.
The hem is rough
It is worth noting that high-quality T-shirts often spend more money on finishing than sewing. .
T-shirts currently on the market that cost less than 80 yuan often selectively ignore the finishing process.
For a T-shirt, the style is also very important. Size, whether it is slim or not, the position of the shoulder line, and the armhole curve are not the criteria for measuring the quality of a T-shirt. As long as the collar, shoulder width and length are appropriate, it is a good fit.
