Why is Cambric weave popular for hotel linens?

Cambric fabric is dense and strong, making it ideal for use in hotel linens such as bedding and towels. It is often calendared, that is, passed through calendar rollers at high pressure and temperature to give it a smooth, flat surface. The warp and weft weave, where threads alternate over each other, means the color will be the same on both sides of the fabric. 

What is Denier and how is it used to measure the density of fabric?

This is a measure of the density of the fabric, which is especially important when it comes to hotel linens. This is a measure of the density of the fabric. It is based on the length of a single strand of silk, about 9000 meters that weigh about one gram. Low-denier fabric will be silky and sheer. Higher denier fabric is thick and durable. A fabric with a width of less than one is known as a microfiber. For comparison, a strand of human hair is about 20 denier.

Dobby Fabric and its Benefits

Dobby fabric is produced on a dobby loom. The fabric usually has a textured feel with a repeated, small geometric pattern woven in. A dobby design enhances the beauty of a product, such as the textured dobby stripes on our Raiya Turkish towel collection.

How does Fiberfill enhance the comfort and structure of bedding?

Fiberfill consists of polyester or polyester blend fibers that are combed and fluffed to mimic cotton’s loft. It adds softness, structure, and comfort to pillows, comforters, and mattress pads.

What is a Flange and how does it elevate the look of hotel bedding?

A flange is a decorative border sewn around the edges of shams, duvets, and comforters. It creates a clean, tailored finish that enhances the visual appeal of bedding.

How does a French Fold keep hotel pillowcases neatly secured?

A French fold uses an inner flap of fabric to hold the pillow securely in place. This construction keeps the case smooth and fitted without buttons or zippers, making it a popular choice for hotel pillowcases.

What does GSM measure and why does fabric weight matter?

GSM stands for Grams per Square Meter. It measures fabric density and helps determine how light, medium, or heavy a textile feels.
Lightweight: under 150 GSM
Medium weight: 150 to 350 GSM
Heavyweight: above 350 GSM

Thicker fabrics, such as Turkish towels
at 600 GSM, offer greater absorbency and plushness.

How does a Gusset improve the shape and durability of pillows?

A gusset is an added fabric panel that increases structure and volume. It helps pillows maintain their shape, provides better edge support, and gives bedding items a more tailored appearance.

What makes the Herringbone weave a classic choice for linens?

The herringbone pattern is made from alternating diagonal twill lines that form a V shape. This weave is known for durability and a timeless, tailored look, commonly used in cotton and wool textiles.

How does Jacquard weaving create intricate patterns in bedding?

Jacquard weaving embeds detailed designs directly into the fabric instead of printing them on top. This creates dimensional texture and adds refined style to bedding such as Jacquard sheet sets and coverlets.

What is Matelassé and why does it resemble quilted fabric?

Matelassé is a thick, textured weave created to mimic the look of quilting. It provides depth, softness, and structure, often used in coverlets, shams, and decorative bedding layers.

Why is Microfiber used in soft and lightweight hotel bedding?

Microfiber is made from ultra-fine synthetic fibers, usually polyester. It is lightweight, breathable, hypoallergenic, and easy to care for. Brushed microfiber offers a warm, velvety texture.

What does OEKO-TEX certification ensure in textile safety?

OEKO-TEX certification verifies that a textile has been tested for substances harmful to human health. All Sobel Westex linens meet this standard, ensuring safe, responsible materials for the home.

Why is Percale a popular weave for crisp, breathable sheets?

Percale uses a tight one-over-one weave that creates a smooth, crisp, matte finish. It is breathable, durable, and commonly chosen for hotel-quality percale sheets.

What causes Pilling and how can high-quality fibers prevent it?

Pilling occurs when loose or short fibers form small balls on the surface of the fabric. Long-staple cottons such as Egyptian, Pima, and Turkish cotton naturally resist pilling, and gentle laundering helps maintain fiber quality.

How does Polyfill mimic the comfort of natural down?

Polyfill is a synthetic fiber designed to imitate the loft and softness of down. It is lightweight, hypoallergenic, mildew resistant, and commonly used in comforters and luxury hotel pillows.

Why is Ring-Spun cotton valued for softness and durability?

Ring-spun cotton is created by twisting and thinning long cotton fibers into a smooth, strong yarn. This process results in stronger, softer, and more durable fabric ideal for bedding and towels.

What makes the Sateen weave feel smooth and luxurious?

Sateen uses a weaving technique that brings more surface threads to the top, creating a silky, lustrous finish. It offers warmth, softness, and a smooth hand feel, making sateen bedding a popular choice for luxury sheets.

How does Thread Count influence the feel and durability of sheets?

Thread count measures the number of threads woven into one square inch of fabric. The best balance of softness and durability is often found between 300 and 600 thread count, depending on fiber quality and weave.

What is Ticking fabric and how is it used to protect bedding?

Ticking is a tightly woven cotton or linen fabric used to cover pillows, mattresses, and cushions. It serves as a protective layer that enhances durability and comfort.

What does Sanforized mean?

When a textile is Sanforized it simply means it is pre-shrunk, so that it will shrink less when washed.

What are Terry and Velour?

Velour is French for Velvet. It is a cloth typically made from very thick materials such as cotton or polyester. Terrycloth, often used for towels and bathrobes, is composed of many minuscule loops capable of absorbing moisture well. It becomes stronger when wet and resists a lot of stress such as tugging. While typically designed with cotton, it is also commonly designed with bamboo or microfiber.

What is Gel-Fiber?

Gel-Fiber is an interchangeable term with Micro-Fiber and references the size of the fiber used in the pillow. The pillows are filled with 100% polyester.

What does Viscose mean?

Once called ‘viscose rayon’, viscose is a material very similar in molecular structure to cotton but is made from several kinds of plants, including bamboo, sugarcane, and soy. It is a versatile material that can mimic the feel of natural fibers like cotton, wool, linen or silk.

What is PETP?

Polyethelyne Terephthalatate (now more commonly abbreviated PET or PETE) is a resin that is used with synthetic fibers in clothing and plastic products for its moisture and water resistance properties.

What does Silpure mean?

Silpure is a patented anti-bacterial treatment used on a variety of fabrics such as furniture coverings, clothing, and is utilized in medical environments. It is made by breaking down silver into microscopic particles that attach to the textile providing long-term protection from microbial growth while also avoiding discoloration of the fabric.
