Circular Knit Interlining

1. Product Overview

In garment manufacturing, some fabrics need a little support but still have to remain soft and flexible. Circular knit interlining is often used in this situation. It is made from knitted fabric produced on circular knitting machines, which gives the material a smooth surface and a certain level of stretch.

Because of this structure, circular knit interlining behaves differently from woven interlining. The fabric can move more easily with the outer garment fabric, which makes it suitable for clothing where comfort and flexibility are important.

Garment manufacturers often use this interlining in shirts, knit garments, dresses, and lightweight fashion apparel. It helps maintain the shape of certain garment parts while still allowing the fabric to feel natural.

In many production lines, the interlining is applied through a fusing process. The adhesive coating on the back melts under heat and pressure, bonding the interlining to the outer fabric. Once fused, the garment parts become more stable but still retain a soft hand feel.

2. Fabric Structure and Materials

This is produced using circular knitting machines. These machines create a continuous tubular knitted fabric by forming loops of yarn. The loop structure is what gives knitted fabrics their flexibility.

Because of this loop structure, the material can stretch slightly and recover when the fabric moves. This is one reason garment manufacturers choose knitted interlining for softer garments.

The yarns used in circular knit interlining are usually polyester or polyester blends. Polyester fibers help maintain stability and durability while keeping the fabric lightweight.

During finishing, an adhesive layer is often applied to one side of the fabric. The adhesive is typically added in small dot patterns. This helps maintain flexibility while still allowing the interlining to bond firmly to the garment fabric during fusing.

3. Key Features

Soft and flexible structure

The knitted construction allows the interlining to move together with the garment fabric.

Comfortable hand feel

Circular knit interlining usually feels softer compared with many woven interlinings.

Lightweight support

It adds stability to garment parts without making them stiff.

Good compatibility with knit fabrics

It works well with stretch fabrics and other soft materials used in fashion garments.

Reliable fusing performance

Fusible versions bond well with fabrics during the heat pressing process.

4. Manufacturing Process

The production of circular knit interlining starts with yarn preparation. Polyester or blended yarns are first prepared and fed into circular knitting machines.

The knitting machine forms loops of yarn continuously, creating a tubular knitted fabric. This structure provides flexibility and allows the fabric to stretch slightly.

After knitting, the fabric may be opened and processed into flat fabric rolls. At this stage, finishing treatments such as heat setting and stabilization are applied to control the fabric dimensions.

If the product is designed to be fusible, adhesive coating is applied to one side of the fabric. The coating process usually creates small adhesive dots that melt during garment fusing.

Once the finishing process is complete, the fabric is inspected, rolled, and prepared for delivery to garment manufacturers.

5. Applications

Circular knit interlining is often used in garments where softness and flexibility are important.

Typical applications include:

• shirts

• knit garments

• dresses

• lightweight jackets

• women’s fashion apparel

• stretch fabric garments

Because the material bends and stretches easily, it works well with fabrics that require comfort and natural movement.

7. FAQ

Q1: What is the difference between circular knit interlining and warp knit interlining?
Circular knit interlining is produced on circular knitting machines and often has more stretch, while warp knit interlining is made on warp knitting machines and usually has slightly better stability.

Q2: Is circular knit interlining suitable for stretch fabrics?
Yes. Because of its knitted structure, it works well with fabrics that require flexibility and comfort.

Q3: Can circular knit interlining be fused to garments?
Yes. Many products include adhesive coating so they can be bonded to fabric through heat and pressure.
