Types of bias binding: what are they, and how are they classified?

Before we go into the different types of bias seams, it is important to explain what they are and which sectors and industries use our bias tapes. A seam is the union between two or more pieces of fabric, leather or other materials that are joined employing stitches. Byetsa’s range of bias binding tapes is so wide that it can be used in a wide variety of sectors.

For a seam to be of high quality, it must comply with the ISO 4916:1991 standard. Before this regulation appeared, seams were very simply classified into flat, overlapped, edged and selvedge seams. Today, they are classified according to the following eight types of bias binding seams.

Type 1: overlapping seams

A type of stitching which starts with two or more pieces of material overlapping and joined near the edge with one or more rows of stitches. Used to create neat seams for lingerie or T-shirts.

Type 2: overlapping seams

In this type of seam, two or more materials are overlapped, which are joined with one or more rows of stitches.  Within this type of seam, there are several options:

  • Flat.  Strong seam with fabric edges, commonly used to protect jeans or garments that have a tendency to fray.

  • French. Used for rain wear, jackets, and dresses.

Type 3: bonded seams

They are formed by folding a strip of piping over the edge of the piles of material. Both edges of the edging are then joined to the material with one or more rows of stitching. The resulting edge is neat, and the seam can be exposed to view without any problem. Used for shirt collars.

Type 4: flat seams

Seam in which two fabric edges are joined over stitches. Used in garments such as underwear or corsetry to achieve a joint where the thickness of the fabric must be tolerated by the seam. In this case, the edges are butted, not overlapped.

Type 5: decorative or ornamental stitching

It consists of a series of stitches along a line or after an ornamental design on a fold of material. This type of stitching would not be possible without the properties of elastic bias binding.

Type 6: selvedge seams

This type of bias binding includes seams in which the edges are overlocked by stitching and are used when finished edges are required. Useful for producing neat edges such as hems or invisible hems on briefs or linings.

Type 7: joining of separate elements

For this type of seam, additional components such as elastic bands are required at the edges.

Type 8: simple construction

Consists of a piece of fabric that becomes two edges. It is commonly used in loops.

What does the quality of bias binding seam types depend on?

The quality of bias binding seam types depends on three fundamental elements:

  • Seam size. This is measured by the depth, length, and width of the seam.

  • Seam slip force. This is the amount of force required to pull out a total of ¼ of the opposing sets of threads perpendicular to the seam line.

  • Sewing force. Refers to the force required to open the seam.
