Tie Interlining

Definition and Overview

Tie interlining is the interlining used inside a tie, from the wide blade and narrow blade to the section that becomes the knot. It provides fullness and shape retention that are hard to achieve with the outer fabric alone, and it also affects how easy the tie is to knot and how it recovers after being untied.

Although interlining is a hidden material that cannot be seen from the outside, it has a major effect on the feel of the tie. If the interlining is too thick, the knot becomes large and stiff; if it is too thin, the tie may look flimsy or lose its shape.

Areas Used and Role

In general, an interlining cut to match the shape of the tie is inserted between the outer fabric and lining. Not only the wide section on the blade side, but also the design of the area that forms the knot, affects the knot size and the appearance of the indentation called a dimple.

The interlining does more than reinforce the outer fabric; it also plays a role in adjusting the return after sewing and the vertical drape. Since ties are often made by closing the center with blind stitching or similar methods, the thickness and resilience of the interlining also affect ease of handling during sewing.

Materials and Types

Tie interlining includes products made mainly of wool, products combining wool and synthetic fibers, and products based on woven or nonwoven fabric. Depending on the material composition, structure, and industry weight, softness, resilience, thickness, and lightness differ.

In tailoring, non fusible interlining inserted without adhesive is sometimes used. On the other hand, there are also fusible types, but because the outer fabric of a tie may be made of materials such as silk that are sensitive to heat and pressure, careful confirmation is required before use.

• Soft interlining: considered when a supple knotting feel and a light finish are desired.
• Firm interlining: considered when knot shape retention and contour are important.
• Thick interlining: easier to give a three-dimensional look, but caution is needed because the knot tends to become large.
• Thin interlining: easier to finish lightly, but depending on the thinness of the outer fabric, the interlining may not be sufficiently noticeable.

Selection and Precautions

Select the interlining in combination with the outer fabric's thickness, weave density, stretch, luster, and pattern appearance. For thin and delicate outer fabrics, choose an interlining that does not show through the surface and does not give excessive stiffness. For thick or bulky outer fabrics, avoid layering the interlining so much that it becomes too hard.

When deciding on a candidate, make a sample with the actual outer fabric and lining, and check the knot size, how smoothly it ties, the appearance of the dimple, and wrinkles or recovery after untying. It is important to evaluate not only the hardness of the interlining itself, but also the combination with the outer fabric.

Precautions for Fusible Bonding and Sewing

When using fusible interlining, set the temperature, pressure, and time according to the heat resistance of the outer fabric. If the conditions do not match, there is a risk of poor adhesion, surface fading, adhesive bleed-through, and bubbling, which is a lifting or blister-like appearance defect.

With non fusible interlining, align the grain during cutting so that the edges of the interlining do not show through the outer fabric. If the interlining and outer fabric are pulled too much during sewing, it can cause twisting or waviness, so adjust the needle, thread, and sewing allowance while taking the interlining thickness into account.

Frequently Asked Questions

Should tie interlining be fusible interlining or non fusible interlining?

Choose according to the desired construction and outer fabric. Non fusible interlining makes it easier to take advantage of the interlining's natural fullness and suppleness, while fusible interlining can help stabilize the process. However, for fusible types, the effect of heat on the outer fabric, peeling, and changes in appearance should be confirmed through sampling.

What problems can occur if tie interlining is too stiff?

The knot may become larger than necessary, or it may feel stiff when tied. The suppleness of the outer fabric may also be reduced, making the knot shape look unnatural. Confirm the knotting feel and appearance through samples including the outer fabric and lining.

What should be noted when using tie interlining with a thin silk outer fabric?

Consider an interlining that is thin and blends well, so that the texture and edges of the interlining do not show through the outer fabric. When fusing, changes in luster, fading, and bleed-through may become noticeable, so conduct adhesion tests on the same outer fabric and establish the conditions before mass production.
