How to Test the Cutting Performance of Stainless Steel Tailor Shears?

Scissors & shears are a type of hand tool used for cutting things. When customers purchase scissors & shears, their cutting performance should be considered first. Stainless steel tailor shears are production tools for clothing factories, and their cutting performance is particularly important. So when buyers of stainless steel tailor shears go to stainless steel scissors factories to inspect goods or receive goods from stainless steel tailor shears suppliers, they will randomly inspect some finished stainless steel tailor shears to test their cutting performance. The stainless steel scissors factory as well need to test the cutting performance of stainless steel tailor shears before packaging them.
However, how should we test for objectively getting the cutting performance of a stainless steel tailor shears? The simplest and most useful method is to use stainless steel tailor shears to cut fabric directly. But what material is reliable to cut? Most of scissors factories use polyester fabric as the cutting material to test the cutting performance of stainless steel tailor shears. It is possible to test the cutting performance of household or office scissors by cutting polyester fabric, but to test the cutting performance of stainless steel tailor shears is not very reliable. Compared with cotton fabric, polyester fabric is harder and more brittle. There is also a layer of PU or PVC on the bottom of polyester fabric. As long as stainless steel tailor shears can cut through polyester fabric, there will generally be no fabric tearing or fraying on the cuts of polyester fabric. However, if the stainless steel tailor shears is cutting cotton fabric, it will be different. Yarn made of cotton is relatively soft and tough. If the cutting ability of stainless steel tailor shears is not very good, even if the cotton fabric is cut through, there will be yarn burrs or even tearing at the cuts. Since that’s the case, why do most of scissors factories still use polyester fabric as the cutting material to test the cutting performance of their stainless steel tailor shears?
One reason is that these stainless steel scissors factories do not have high requirements for the stainless steel tailor shears they produce. They believe that as long as the appearance of the stainless steel tailor shears looks not bad, the cutting performance is not very poor, and the price is bit lower, customers will generally accept it. The fact is that many buyers who deal in cheap merchandise accept this view because the price is a bit lower, but buyers who deal in their own brand do not think so.
The second issue is cost. The fabrics used for testing cutting performance are some scraps or discarded fabrics left behind by clothing or bag factories after cutting fabrics for making productions. The scraps or discarded fabrics of polyester materials are relatively easy to obtain, and the cost of obtaining them is much lower than that of cotton fabrics.
Then, how do professional and reliable stainless steel scissors manufacturers test the cutting performance of stainless steel tailor shears? How do professional and experienced buyers of stainless steel tailor shears test the cutting performance of stainless steel tailor shears?
Firstly, the cutting material used to test the cutting performance of stainless steel tailor shears must be cotton denim. The yarn of cotton denim fabric is thick and tough, and the fabric is relatively thick. If a pair of stainless steel tailor shears can cut through cotton denim fabric neatly and smoothly and produce perfectly neat cuts with no fabric tearing or fraying, there will be no any problem for cutting other fabrics with this stainless steel tailor shears.
Secondly, conduct sectional cutting tests on the cutting blades of stainless steel tailor shears. The cutting use of stainless steel tailor shears mainly involves three parts: the tip part of the scissors blade (usually called the tail of the scissors in the scissors factory), the middle part, and the part near the pivot pin position.

The part near the pivot pin position is the most stressed, if the quality of stainless steel tailor shears is not too poor, it’s usually no problem for cutting the fabric with this part. The difficulty lies in the fact that both the tip part and middle part of the stainless steel tailor shears have excellent cutting performance. So many buyers often find this phenomenon. When using stainless steel tailor shears, the tip part and the part near the pivot pin position of some stainless steel tailor shears can cut fabric, but there always is fabric tearing or fraying when cutting fabric in the middle part of the stainless steel tailor shears. However, the middle part and near the pivot pin position of some stainless steel tailor shears can cut fabric, but the tip part of the scissors cannot cut the fabric. The reason for this may be that the stainless steel manufacturer has chosen the wrong stainless steel material or poor grinding technology, or it may be that their assembly and adjustment techniques are not up to standard.
To ensure that any parts of the blade of a stainless steel tailor shears can cut fabric cleanly, in addition to selecting the right stainless steel material and using advanced grinding techniques, the assembly workmanship of the scissors must also be mature and stable, adjusting the blade after assembly is also important. At first the blades of stainless steel tailor shears should be sharp enough, then after manual operation by skilled workers, the two blades are assembled perfectly, and then carefully adjusted by skilled workers, so that the various parts of the scissors that rub against each other during cutting are relatively balanced, in order to ensure that the fabric cut by each part of the scissors is neat, without yarn burrs or tearing edges.
This is an interesting phenomenon, a stainless steel scissors manufacturer who can do a good job in assembling and adjusting seemingly unimportant working procedures, whether it is selecting steel or grinding technology, will not be bad. However, a stainless steel scissors manufacturer who usually does not pay much attention to product quality small details is not necessarily to be able to do assembly and adjustment working procedures well even if they are willing to spend costs on steel and advanced grinding machinery. Because this is a long-term overall task, the overall quality awareness and mature craftsmanship of workers are gradually cultivated in the stainless steel scissor factory that dedicated to the long-term stability of product performance and quality, and cannot be achieved overnight.
Now we know how to test the cutting performance of stainless steel tailor shears, right? It is to use stainless steel tailor shears to directly cut cotton denim fabric. First, use the tip part of the stainless steel tailor scissors to cut it, then use the middle part to cut it, and then use the part near the pivot pin position to cut it, finally, use the entire blade of the scissors to cut it a long straight cut. In these operations, feel whether the cutting is smooth, and then observe whether the cut of the cotton denim fabric is neat, whether there are any cotton yarn’s burrs and tearing or fraying at the cut. If all the above mentioned items are acceptable, the performance of this stainless steel tailor shears is definitely good. Even if there may be some small flaws in the entire stainless steel tailor shears, the good performance of the stainless steel tailor shears will make your customers overlook these small flaws, and your brand will gain more market recognition.

Of course, you can also have higher requirements, requiring stainless steel tailor shears to be able to cut through two or even three layers of cotton denim neatly. It depends on what standard you have in mind?
