Perma Core® Ultimate 180

In modern light industry and high-precision sewing, not only fabrics and equipment but also threads play a vital role. The quality of the sewing thread determines the strength, stability, and appearance of the seam. This is especially important when sewing thin fabrics and creating subtle stitches, where the thinnest yet strongest thread is required.

Perma Core® Ultimate 180 from Gutermann is an ultra-fine industrial-strength sewing thread, developed specifically for high-speed sewing on modern machines. It combines exceptional strength, stability, and a micro-fine structure, ensuring perfect stitching without bulges or breaks. These threads are the result of years of research and engineering by the German company Gutermann, a leader in textile accessories.

Advantages

1. Innovative Core-Spun Construction

Perma Core® Ultimate 180 is a core-spun thread: a polyester core wrapped with polyester fibers. This technology provides high strength, stability, and minimal stretch while remaining extremely thin. Unlike traditional monofilaments, it does not break at high sewing speeds and maintains a stable shape in the stitch.

2. Maximum Fineness — Minimal Visibility

Ultimate 180 is one of the thinnest threads in the Gütermann professional line. It provides an ultra-fine stitch, virtually invisible on the surface of the fabric. This is especially important when sewing lightweight, sheer, or knit fabrics, where standard threads can create bulges and distort the garment.

3. Tensile Strength

Despite its diameter, the thread maintains high strength and is resistant to stress. This makes it suitable not only for decorative seams but also for functional joining.

4. High Abrasion and Temperature Resistance

Perma Core® Ultimate 180 demonstrates excellent resistance to abrasion, heat treatment, and chemical exposure, which is especially important in the production of garments that require repeated washing and ironing.

5. Ideal for high-speed sewing

The thread performs reliably on industrial equipment, withstanding high speeds without breakage or skipping. This significantly increases productivity and reduces defects.

The ultra-thin structure and high strength make these Ideal for a wide range of professional and industrial sewing applications:

• Sewing thin and delicate fabrics

Ultimate 180 threads are ideal for fabrics such as silk, organza, chiffon, cambric, microfiber, and lightweight synthetics. They do not create bulk, do not stretch the fabric, and are invisible on the face.

• Making lingerie and swimwear

In lingerie production, invisible seams, softness, and durability are especially important. Perma Core® Ultimate 180 delivers exactly this: a smooth, invisible seam that’s undetectable on the skin while securely joining garment elements.

• Sportswear Sewing

These threads withstand high loads, abrasion, and frequent washing, making them suitable for activewear, compression garments, and sports textiles.

• Technical Textiles

Used in the production of medical textiles, filters, gloves, and protective clothing—anywhere strength and minimal thread diameter are important.

• Decorative Seams and Trims

Fine stitching creates a sophisticated and stylish look. The thread can be used for decorative purposes, including embroidery and edge trimming, hemming, and piping.

• Knitwear Sewing

Ultimate 180 thread handles stretch fabrics and materials with ease. It does not tear when stretched and does not affect the elasticity of the finished product.

Instructions for use

To achieve optimal results when working with Perma Core® Ultimate 180 thread, it is important to consider a few nuances:

Needle selection

For sewing with #180 thread, we recommend using #60 or #65 needles with a sharp tip. For stretch fabrics, ball-point needles are suitable.

Tension adjustment

Since the thread is very fine, it is important to properly adjust the tension of the upper and lower threads. Excessive tension can cause the fabric to puckered, while loose tension can skipped stitches.

Speed ​​Control

Although the thread is designed for high-speed sewing, it is best to reduce the speed when sewing particularly fine fabrics to avoid fabric shifting and stitch irregularities.

Bobbin Use

Can be used on both the top and bottom threads. For the finest, most invisible stitch, it is recommended to use Ultimate 180 on both sides.

Storage

Store spools in a dry place, away from direct sunlight and heat sources. This will help maintain the strength of the fibers and the vibrancy of the color.
