Whether the quality of the T-shirt is qualified 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. The wearing comfort is naturally very low unless Special modifications are made on the structure 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, and is much cooler when worn than a cotton T-shirt. 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, without hardware such as zippers and buttons , and very few excipients are used. 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, and 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 overlock stitching, and an overlock machine is required. The overlock stitches only need to be dense and neat; for flat stitching, and an interlock stitching machine for hem and cuffs, the stitches must 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 collar, binding strips, closing side seams, hem and cuff seams, these sewing processes only take 12-15 minutes, and skilled sewing workers can Faster, but not much different.
Generally, processing factories usually require sewing workers on a piece-by-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 produce different quality levels.
Sewing workshop
The finishing after sewing is the final check of quality, including thread cutting and 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 often take more time and cost more to finish.
Post-inspection
So, judging the processing quality is just to judge the level of sewing workers in the processing factory and the post-inspection The overall requirements are high or low.
In terms of cost, the processing fee for a general-quality T-shirt only costs 7-8 yuan, and the processing fee for large-scale products is 4-6 yuan. The processing fee for good-quality T-shirts will reach 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 has its own characteristics.
Neckline
This cloth collar and T-shirt are more integrated.
2*2 ribbed collar, with wide ribs, rough collar, big difference with the fabric of the clothes itself, obvious collar, mostly used for coats;
1*1 ribbed collar, with ribs The strips are narrow, the neckline is relatively delicate, and they are mostly worn inside.
No matter which kind of collar you use, there is no difference in quality.
Ribbed
The sewing of the collar is divided into single needle, double needle and triple needle. You can tell from the sewing stitches.
Two and three books
Businesses often use two and three books to target consumption. Misleading, thinking that two-book needles and three-book needles are more labor-intensive and high-end.
When using the same sewing thread, the more needles there are, 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-book needles for knitted fabrics. We do not need to pay for two-book needles and three-book needles.
In addition, the sewing thread is related to whether the T-shirt is strong.
At present, the world generally believes that British Coats sewing thread is the best, and its 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 retains the elasticity of the original ribs and is easy to wear when worn. It is easy to take off and requires good elasticity in the ribbing and a 2-layer collar.
The collar made by the overlocking method consists of 5 layers (4 layers for ribs and 1 layer for the body). It is characterized by its thick collar, durability, and resistance to deformation after long-term use. It has lower requirements for ribs, but has poor elasticity. , not easy to put on and take off, good shape retention.
No matter which way you use the collar, it will not affect the quality of the T-shirt.
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 are often tied with strips ( Use the original fabric) to cover all the seams at the bottom of the collar and the bottom of the shoulders. The better the T-shirt, the less exposed the seams and seams will be.
Bundling strips look neat
Using strapping strips can reduce lateral friction and increase aesthetics. This is A must-have 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 easily fall off. The same goes for the seam line. The denser the line, the higher the quality of the T-shirt.
Stitches are flat
Overlock thread
Generally speaking, the higher the stitch density and overlock thread density, the higher the quality of the T-shirt.
The above aspects involve design or equipment reasons, so the following quality problems are mainly due to the sewing workers’ operation problems.
Are the lengths of the front and back pieces consistent?
The front and rear pieces are of different lengths
The inconsistent length of the front and rear garments is a very important quality issue.
Are the cuffs and hem seams even and wrinkled?
Uneven seams
The hem is wrinkled
Have the threads been cleaned?
The thread ends are not cleaned
The seams and multi-thread ends 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 stop is rough
It is worth noting that high-quality T-shirts have flowers on the back The money is often more 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.
