GB 18383-2025 General technical requirements for products with filling materials 1 Scope This document defines the terms and definitions related to products with filling materials, specifies their requirements, sampling, decision rules and identification, and describes the corresponding test methods. This document is applicable to products with filling materials. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies. GB/T 2910 (all parts) Textiles - Quantitative chemical analysis GB/T 6499 Test method for percentage of trash content in raw cotton GB/T 8170 Rules of rounding off for numerical values & expression and judgment of limiting values GB/T 10288 Test method for down and feather GB 15979 Hygienic requirements for disposable sanitary products GB 18267-2013 Cashmere GB 18401 National general safety technical code for textile products GB/T 20223 Cotton linter GB/T 24252-2019 Silk quilts GB/T 28024 Determination of sensory odours for products with filling materials GB/T 28025 Determination of the residual chlorine in products with filling materials - Water extraction method GB/T 43811 Determination of sensory odours for products with filling materials FZ/T 01026 Textiles - Quantitative chemical analysis - Multinary fibre mixtures FZ/T 01057 (all parts) Test method for identification of textile fibers FZ/T 01101 Textile test method - Fiber content - Quantitative physical analysis SN/T 3335 Rules for the inspection of microbiological specification on import and export textiles   3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 filling materials collective term for natural fibres, chemical fibres, and their blends used for stuffing and padding 3.2 products with filling materials products with filling materials and those processed into batts, felts, etc., for stuffing and padding Note: Products with filling materials are categorized into those for domestic use and those for non-domestic use. 3.3 daily use products with filling materials filling materials that are in close contact with the human body in daily life Note: Daily use products with filling materials mainly include apparel and footwear items such as winter coat, down garments, cotton clothing, cotton shoes, and cotton hats; bedding items such as quilts, mattresses, pillows, and cushions; upholstered furniture such as mattresses, sofa, and seating or reclining pads; toys such as plush toys. 3.4 non-daily use products with filling materials products with filling materials excluding those for daily use Note: non-daily use products with filling materials mainly include building insulation materials, agricultural insulation materials, transportation packaging materials, decorative materials, building acoustic insulation materials, etc. 3.5 textile waste for medical purpose filling materials that are discarded by medical and health institutions Note: Textile waste for medical purpose primarily includes discarded medical dressings such as degreasing cotton and degreasing gauze, clothing of medical staff and patients, filling materials, and other fibre materials.   3.6 foreign matter collective term for products without filling materials mixed into filling materials 3.7 fibre waste single or bundled fibres that fall off, are removed, or become detached during the production and processing of fibres or fibre products 3.8 fibre products waste edges and trimmings of fibre products other than fibre waste generated during the processing and production of fibre products, such as thread ends and fabric scraps, batting, and felt pads 3.9 unused fibre products waste waste materials generated during the production and processing of fibres and their products (such as spinning, weaving, dyeing, cutting, etc.), as well as clothing, household fibre products, industrial fibre products, and other fibre products that are discarded without being used Note: Waste materials include fibre waste and fibre products waste. 3.10 used fibre products waste fibre products that are discarded after being used Note: including clothing, household fibre products, industrial fibre products, and other fibre products that are discarded after being used. 3.11 mechanically recycled fibre fibre produced by processing fibre products, fibre waste, or fibre products waste as raw materials by physical and mechanical methods Note: Physical mechanical processes involve the use of mechanical methods to cut, tear, and release fibre products waste, fibre products and their wastes to obtain fibre 3.12 recycled chemical fibre fibres obtained from used and unused fibre products waste or waste polymer materials through processes such as physical melting, chemical regeneration, or physicochemical methods Note 1: Physical melting process refers to the reprocessing of thermoplastic used and unused fibre products waste, or waste polymer materials, through heating and melting. Chemical regeneration process refers to the procedure of depolymerization, impurity removal, repolymerization, or decomposition of used and unused fibre products waste or waste polymer materials under certain chemical process conditions to produce new raw materials. Physical melting process refers to the he process of blending and modifying thermoplastic waste or old fibre products, or waste polymer materials, through heating and melting under the action of different functional additives. Note 2: To ensure the subsequent performance of recycled chemical fibres, some of them contain virgin fibres. 4 Requirements 4.1 General The following materials shall not be used as the raw materials for processing products with filling materials: a) textile waste for medical purpose; b) used funeral fibre products; c) fibre products from epidemic areas that cannot be proven to be uncontaminated; d) used and unused fibre products waste prohibited from import by the state; e) other severely contaminated or toxic and harmful substances. 4.2 Requirements for the filling materials of daily use products with filling materials 4.2.1 The following materials shall not be used as the filling or padding raw materials for processing daily use products with filling materials: a) contaminated fibres; b) used and unused fibre products waste (except for uncontaminated fibre waste and those meeting the requirements specified in 4.2.2); c) mechanically recycled fibre (except for those meeting the requirements specified in 4.2.2); d) cotton linters with a hand-staple length less than 13 mm as specified in GB/T 20223; e) fibre waste, fibre products waste, or mechanically recycled fibre that have undergone decolorization or bleaching treatment; f) animal fibres that have not been thoroughly cleaned; g) moldy or deteriorated filling materials. 4.2.2 Mechanically recycled fibre or uncontaminated fibre products waste may be used as filling or padding raw materials for products such as upholstered furniture after undergoing disinfection. By-products generated during the silk reeling process, such as long waste silk and gilled waste, as well as cleaned animal fibre, may be used as filling or padding raw materials for daily use products with filling materials. 4.2.3 Except for recycled polyester fibre , other recycled chemical fibres shall not be used as filling or padding raw materials for products with filling materials intended for infants aged 3 years (36 months) or below 4.3 Technical requirements for daily use products with filling materials 4.3.1 For daily use products with filling materials, hazardous impurities such as metal objects or sharp items (e.g., needles, iron wires, wooden sticks) and noticeable dust shall not be detected. 4.3.2 The content of short fibres with a length of 13 mm or less in daily use products with filling materials shall not exceed 25%. This requirement does not apply to products such as cushion felts, batting, or daily use products with filling materials containing kapok, down, or feathers. 4.3.3 The foreign matter content of filling materials in daily use products with filling materials shall meet the requirements specified in Table 1.
