Do you know how to distinguish between flat knit and cut and sew?

We translate with Google Translate. You can contact us if you have any question.

Nice to meet you all!

I’m Nakamura, who joined the company halfway from last year!

Too long in vain in the apparel industry! I would like to make a blog that makes full use of my experience.

Thank you for your cooperation!

Speaking of knit

Speaking of knit, it seems that most people think of weft knitting, which is typified by a sweater.

But did you know that knits include vertical knits, circular knits, etc. in addition to horizontal knits? I’m sorry for the rudimentary content, but please keep in touch.

We will omit the weft knitting because our experts always introduce it on our blog.

This time my previous job was a circular knitting shop Sun, so today I would like to introduce you to the familiar circular knitting.

Even though they are the same knit, the structure of flat knit and circular knit is completely different.

Speaking of flat knitting, threads come and go from side to side like a home machine (in my house, my mother always untied my brother’s sweater and knitted my sweater … Furu ~!). It runs back and forth, but in circular knitting, the threads run in a spiral shape and the fabric is knitted in a tubular shape.

While winding it at the bottom with the knitting machine shown in the photo, knit it according to the length (30 to 50 meters) after processing one roll. There are about 20 to 30 thread cones around the top of this machine, but this number of knitting is basically the number of steps that can be knitted in one round.

The characteristic of circular knitting is that a large amount of yarn is required at one time, which is a big difference from weft knitting with one piece or at least one yarn.

Then, this knitted raw machine (spiral shape) is sent to the rearranging processing plant for post-processing such as washing, opening, and squeezing.

Then, by cutting a piece of tubular fabric vertically in the middle of the process, it becomes a rectangular knit fabric for the first time.

In the case of flat knitting, the body, sleeves, etc. are linked, washed after sewing, and sewn, but in the case of circular knitting, they are washed at the fabric stage and post-processed such as sewn.

Since such a large-scale process is required, circular knitting is efficient but not suitable for small lot production.

Also, because it cannot be molded like weft knitting, it is cut from the fabric and then sewn (saw), which is called a cut and sew.

By the way, when cutting and sewing from a rectangular knitted fabric instead of molding with flat knitting, it is called a knit saw.

So the question is!

Do you guys look at a sweater or T-shirt and see the difference between flat knitting and circular knitting?

What is the easiest way to tell?

Most of the people who read this blog are familiar with weft knitting, so many of you will understand it, but it is a fact that there are many people in the same industry who do not know it!


It was to see the specifications of the hem and cuffs! (Ignore the voice of Shomona! (Sudden Kansai dialect !!))

In flat knitting, most of the knitting is ribbed or a plain bag, but with a cut and sew, it cannot be finished without a seam allowance because it will be unraveled from the cut surface. Therefore, sewing (various specifications) is required.

If you look here, it’s obvious.

Flat knitting (ribs, bag knitting)

Circular knitting (single needle stitch)


So I would like to continue writing about cut and sewn!

The title photo is a photo of Lake Okutama on my hobby road bike, which has nothing to do with the content.

I am thrilled to be able to climb to such a deep mountain with my own feet!

It would be nice if I could write about my hobbies in the future … What will happen …

I would like to make this the first blog with such thin content.

Nakamura, who has been a member of the company since last year while being a Rotor, told me!

See you again!
