Scope

Main Technical Content: 4. Classification and Dimensions 4.1 Classification 4.1.1 Classification by straw mat raw materials: - Natural straw mats - Reed straw mats 4.1.2 Classification by straw mat size: - Single bed straw mats - Double bed straw mats 4.2 Dimensions The dimensions of straw mats are divided into length and width: - Length: 1900mm, 1950mm, 2000mm, 2100mm; - Width: 900mm, 1000mm, 1100mm, 1200mm, 1500mm, 1800mm; - Other special requirements shall be determined through consultation between the supplier and the buyer. 5. Processing 5.1 After the straw stalks used for weaving straw mats are naturally dried, those with a diameter between 1.2mm and 2.5mm are selected. The roots and stems of the straw stalks are removed to ensure uniform texture and consistent color. The dried straw stalks are then used for weaving straw mats. 5.2 Formaldehyde solution shall not be used for soaking during the processing. 6. Requirements 6.1 Appearance requirements 6.1.1 The straw mat should have a uniform color, a smooth surface, no frayed edges, no mold growth, and no obvious color differences. 6.1.2 The weaving of the straw mat should be tight, with no obvious looseness. 6.1.3 The width of the fabric sewn around the edge of the straw mat should be no less than 30mm. 6.2 Dimensional deviations shall comply with Table 1. Table 1 Dimensional Deviations Dimension Unit Deviation Length mm ±10 Width mm ±5 Folded mat ±10 6.3 Physical and Mechanical Properties 6.3.1 The moisture content of the straw mat shall comply with Table 2. Table 2 Requirements for Moisture Content and Tensile Strength Parameter Unit Requirement Moisture content % 8–15.9 Tensile strength N ≥200 The straw mat shall not have any broken threads or broken straw fibers. 6.4 Limits on Harmful Substances 6.4.1 The formaldehyde emission and total volatile organic compounds (TVOC) shall comply with Table 3.
