Some standard content:
GB/T 5709 -1997 This standard is a revision of the national standard GB5709-85 "Textile Terminology (Nonwoven Fabrics)" based on the international standard. This standard includes terms and definitions for the web-forming and consolidation processes of nonwoven fabrics and their final products, nonwoven fabric raw materials and properties. The definition of "nonwoven fabric" adopts the international standard ISO9092:1988 "Textiles-Nonwoven Fabrics-Definitions". The production process and product terms of nonwoven fabrics adopt the international standard ISO11224:1993 "Textiles-Nonwoven Fabrics Web-forming and Bonding Vocabulary" and the 1996 draft of the international standard to ISO11224, and retain some nonwoven fabric product terms named after the process in the original standard. This standard does not include terms for stitchbonded fabrics, nor does it include product terms named after the purpose. From the date of entry into force, this standard replaces GB5709-85 "Terms of Textiles (Part of Nonwovens)" and FZ60002-91 "Definition of Nonwovens". Appendix A and Appendix B of this standard are informative appendices. This standard is proposed by the China National Textile and Apparel Council. This standard is under the jurisdiction of the Basic Standards Sub-Technical Committee of the National Technical Committee for Textile Standardization. The drafting unit of this standard: Standardization Research Institute of the China National Textile and Apparel Council. The main drafters of this standard: Chen Qunrong and Zheng Yuying. 1 Scope National Standard of the People's Republic of China Textiles·Nonwovens Textiles-Nonwovens-Terms This standard specifies the terms and definitions related to the production process of nonwovens and their products.

The orientation of the fibers depends on the output speed of the web and the speed of the conveyor belt. 2.1.16 Cross-laid web A web formed by the cross-laid web method. 2.1.17 Wetlaying A method of making a web from a suspension containing short fibers using improved papermaking technology. 2.1.18 Wetlaid web A web made using a wetlaying method. 2.1.19 Meltblowing A method of extruding molten polymer into a high-speed hot air stream to form short fibers, which are then cooled and gathered on a moving mesh curtain to form a web. 2.1.20 Meltblown web A web made using a meltblown web method. 2.1.21 Spinlaying A method of extruding a polymer melt into filaments through a spinning head and laying them on a moving mesh curtain to form a web. 2.1.22 Spunlaid web A web made using a spinning web method. 2.1.23 Flashspinning · An improved spinning web method. After the polymer solution is spun through the spinneret, the solvent evaporates quickly, causing the single filaments to split into fine fibers and deposit on the moving mesh to form a fiber web. 2.1.24 Flashspun web A fiber web made by the flash spinning method. 2.1.25 Thermobonded web A fiber web bonded by thermal bonding. 2.2 Web bonding process 2.2.1 Bonding A method of combining fiber webs into nonwoven fabrics by chemical methods (such as gluing or dissolving) or physical methods (such as entanglement or heat) or a combination of methods. Bonding can be overall (such as full or surface bonding) or limited to specified, discontinuous parts (such as point or print bonding). 2.2.2 entanglement Method of forming nonwoven fabric by mechanically entangling the fibers in the web to increase the friction between the fibers. 2.2.3 thermal bonding Method of bonding the web as a whole (e.g., full or surface bonding) or only in specified, dispersed parts (e.g., point bonding) by using hot melt adhesive materials with or without pressure through heat or ultrasonic treatment. The hot melt adhesive material can be a single component fiber, a two-component fiber or a powder. The web can be composed of heat-sensitive materials in whole or in part. 2.2.4 chemical bonding chemical bonding A method of bonding the web by using chemical additives (including adhesives and solvents) with the help of one or a combination of techniques such as dipping, spraying, printing and foaming. 2.2.5 physical bonding physical bonding GB/T 5709—1997 A method of bonding the web by physical means, such as mechanical treatment and heat treatment. 2.2.6 Mechanical bonding is a method of combining fibers by entanglement of fibers, such as needle punching, high-pressure air flow or water jet. 2.2.7 Needle punching is a method of combining fibers by entanglement of short fibers or filaments in a fiber web with specially designed needles or piercing needles. 2.2.8 Hydroentangling is a method of combining fibers by entanglement of short fibers or filaments with a high-pressure water jet, also known as "jet spun web". 2.2.9 Calendar bonding is a method of thermally bonding a fiber web through the jaws of a pair of heated rollers (one of which is heated). The roller surface can be a concave-convex pattern or a flat surface, or a blanket roller can be used. 2.2.10 Point/print bonding is a method of thermally or chemically bonding the fiber web in dispersed areas according to a predetermined pattern by heating and pressurizing the pattern contact points on the surface of the roller. 2.2.11 Oven bonding A method of thermally bonding a web by passing it through a hot air oven. The airflow may flow along the length of the web or from one or both sides of the web (tunnel oven) or through the thickness of the web (straight-through oven). 2.3 Final product 2.3.1 Nonwoven A sheet, web or batt made by combining directional or randomly arranged fibers by friction, cohesion or bonding or a combination of these methods. It does not include paper, woven fabrics, knitted fabrics, tufted fabrics, stitched fabrics with stitched yarns, and wet-felt felt products. The fibers used may be natural fibers or chemical fibers; they may be short fibers, filaments, or fibrous materials formed on the spot. Notes 1 The difference between wet-laid nonwovens and wet-laid papermaking is that nonwovens should meet one of the following conditions: a) The fibers with an aspect ratio greater than 300 (excluding chemically steamed plant fibers) account for more than 50% of the total mass; b) The fibers with an aspect ratio greater than 300 (excluding chemically steamed sandalwood fibers) account for only more than 30% of the total mass, but their density is less than 0.40g/cm. 2 Viscose fibers are not chemically steamed plant fibers. 2.3.2 Bulky nonwovens Nonwovens whose thickness compression rate is equal to or greater than 20% when the pressure increases from 0.1kPa to 0.5kPa. 2.3.3 Composite nonwovens Composite materials are textile materials whose main components can be identified as nonwovens, or whose nonwoven components cannot be identified but whose weight is greater than any other components. Composite nonwovens can also be a nonwoven fabric that has been pre-bonded with filament or staple yarn. 2.3.4 Coated nonwoven Nonwoven with one or more layers of continuous or patterned coating material uniformly attached to one or both sides. 2.3.5 Drylaid nonwoven Nonwoven made of dry webs bonded by one or more techniques. 2.3.6 Airlaid nonwoven Nonwoven made of airlaid webs bonded by one or more techniques. 2.3.7 Carded nonwoven Nonwoven made of carded webs bonded by one or more techniques. 37 GB/T 5709—1997 2.3.8 Random-laid nonwoven Nonwoven made of random webs bonded by one or more techniques. 2.3.9 Wetlaid nonwoven Nonwoven made by bonding wetlaid webs with one or more technologies. 2.3.10 Meltblown nonwoven Nonwoven made by bonding meltblown webs with one or more technologies. 2.3.11 Spunlaid nonwoven Nonwoven made by bonding spun webs with one or more technologies. 2.3.12 Flashspun nonwoven Nonwoven made by bonding flash spun webs with one or more technologies. 2.3.13 Bonded nonwoven Nonwoven made by bonding spun webs with one or more technologies. 2.3.14 Spunbonded nonwoven Nonwoven made by bonding spun webs with themselves. 2.3.15 Inpregnating bonded nonwoven Nonwoven made by impregnating the web with liquid adhesive and then subjecting it to heat treatment. 2.3.16 Spraying bonded nonwoven Nonwoven made by spraying liquid adhesive on the web and then subjecting it to heat treatment. 2.3.17 Foam bonded nonwoven Nonwoven made by rolling foam adhesive into the web and then subjecting it to heat treatment. 2.3.18 Melting bonded nonwoven Nonwoven made by heating a web with powdered adhesive or bonding fibers. 2.3.19 Calendering bonded nonwoven Nonwoven made by hot-rolling bonding a web with powdered adhesive and bonding fibers. 2.3.20 Needle-punched nonwoven Nonwoven made by consolidating a web by needle-punching. 2.3.21 Hydroentangled nonwoven, spunlaced nonwoven Nonwoven made by hydroentanglement. 2.4 Others 2.4.1 Binder A viscous material used to bind or consolidate a web to make it a nonwoven with cohesion, integrity, strength and other additional properties.
