How to choose hotel/event textiles-2-Moisture Regain in Hotel and Event Textiles - A Comprehensive Guide

Textile Moisture Regain Explanation: Moisture regain refers to the metric that quantifies the degree of moisture absorption by textile materials, expressed as a percentage of the weight of water absorbed relative to the dry material's weight. In the trade of textiles for hotels and events, it is essential to establish a uniform standard for moisture regain for various textile materials to ensure accurate weighing and pricing. This agreed-upon level is known as the standard moisture regain.

Formula: Moisture Regain (%) = [(Wet Weight - Dry Weight) / Dry Weight] × 100%

National Standard Moisture Regain Rates: Warp Yarn at 8.5%, Cotton Cloth at 8%, Polyester-Cotton Blend at 3.06%, and Fabrics at 4.2%.

Yarn Count Interpretation: The larger the number preceding the letter "S", the finer the yarn, which results in lighter, thinner, and softer fabrics. Conversely, smaller numbers indicate coarser yarns leading to heavier, thicker, and more robust fabrics. For instance, bed linen yarn count often ranges from 21s, 30s, 40s, up to 60S, 80S, with rare cases reaching 100s.

Standard Measurement Unit for Yarn: In the textile industry, density is commonly used to represent yarn fineness. Density signifies the number of yarn strands per unit length, typically measured as the number of yarns within one inch or 10 centimeters. According to Chinese National Standards, the density is represented by the number of yarns within 10 centimeters; however, some textile enterprises still prefer to use the traditional method of counting yarns per inch.

Classification of Density:

Warp Density: In the longitudinal direction of the fabric, these yarns are called warp yarns, and their count per inch forms the warp density.

Weft Density: In the transverse direction, these yarns are known as weft yarns, and their count per inch represents the weft density. Warp and weft densities can either be identical or different.

Example: "100% Cotton 60s40s/173*124" denotes that the fabric has a warp yarn count of 60s and a weft yarn count of 40s, with a warp density of 173 and a weft density of 124.

Hotel Fabric Classification:

Woven Fabrics: These are formed by interlacing two perpendicular systems of yarns – the warp (lengthwise) and weft (widthwise) – on a loom according to specific patterns. Most hotel linens such as bed sheets, duvet covers, and tablecloths are examples of woven fabrics.

Nonwoven Fabrics: Created through processes like bonding or stitching, where loose fibers are combined without traditional weaving or knitting. Many disposable laundry bags and slippers provided by hotels are made from nonwoven fabrics.

Pure Fabrics: These fabrics are composed entirely of a single type of fiber, including cotton, wool, silk, polyester, etc. Hotel bed linens, pillowcases, and sheets are usually pure cotton fabrics, also known as all-cotton fabrics.

Blended Fabrics: Made by combining two or more different types of fibers in the spinning process to create blended yarns. Some hotel bed linens, sheets, and pillowcases might be made from blends like polyester-cotton.

Interwoven Fabrics: These fabrics have two directional systems, each using different fiber yarns. A majority of bedskirts and bed runners used in hotels are examples of interwoven fabrics.
