Requirement 4.1 Technical Requirements The technical requirements for linen cotton blended natural color fabrics are pided into two aspects: internal quality and external quality. The intrinsic quality includes six factors: fabric organization, width deviation rate, density deviation rate, breaking strength, unit area quality deviation rate, and fiber content. The appearance quality is fabric defects. 4.2 Grading Regulations: The grade of linen cotton blended natural color fabric is classified as excellent, first-class, and qualified. 4.3 The evaluation of linen cotton blended natural color fabric is based on the unit of piece, density deviation rate, breaking strength, unit area quality deviation rate, and fiber content according to criticism. Fabric organization, width deviation rate, fabric surface defects are evaluated according to the piece. And use the lowest grade as the grade of the batch
