Polyester and polyamide composite partially oriented yarns 1  Scope  This Standard specifies the terms and definitions, product marking, technical requirements, test methods, inspection rules and marks, packaging, transportation, and storage of the polyester and polyamide composite partially oriented yarns. This Standard applies to segmented polyester and polyamide composite partially oriented yarns - total linear density is 60 dtex - 600 dtex; linear density per filament is 1.70 dtex - 5.60 dtex; polyester and polyamide proportional range is 90/10 to 65/35; with circular cross section, natural color, and bright and semi dull. This Standard applies to sheath-core polyester and polyamide composite partially oriented yarns with 100 dtex to 390 dtex total linear densities, 1.60 dtex to 6.50 dtex linear density per filament, 85/15 to 50/50 polyester and polyamide proportional range, circular cross section, which are also naturally colored, bright and semi dull. This Standard applies to partially oriented yarns that are manufactured by the composite spinning process with polyester (PET) and polyamide (PA6). Other polyester and polyamide composite partially oriented yarns may reference to this Standard. 2  Normative references  The articles contained in the following documents have become part of this document when they are quoted herein.

Re-inspection shall not be applicable, if one third of the batch has been used. However, if the consignee can present the relevant proof to prove that this batch will influence the quality of the post processing products and cause serious loss, it shall analyze the cause, clarify responsibilities, and deal with it through negotiation. 7.5.2 Inspection items Same as 7.1. 7.5.3 Group-batch rules Conduct the group-batch based on the original production batch. However, products with the production date interval more than 90 days cannot be considered as a same group-batch number. 7.5.4 Sampling provisions 7.5.4.1 Laboratory samples of each item test in Table 1 and Table 2 are taken according to the provisions of GB/T 6502. 7.5.4.2 With regard to appearance and bobbin weight items, sample size (character code) shall be determined by general inspection level II in Table 1 of GB/T 2828.1-2003 according to batch range. 7.6 Evaluation of re-inspection results 7.6.1 The measured value or calculated value of each item in Table 1 and Table 2 shall be compared to the limit value of the physical index in Table 1 and Table 2 according to the rounding value comparison method in GB/T 8170. The grade shall be evaluated one-by-one. 7.6.2 The inspection items of the appearance and bobbin weight shall confirm the receiving number Ac and refusing number Re based on AQL value of 4.0 of single sampling scheme in Table 2-A of the GB/T 2828.1-2003, under normal inspection according to the 7.5.4.2 sample size. Evaluate according to the requirements in Chapter 5. When the unqualified package quantity ≤Ac, it is deemed as the original grade. When the unqualified package quantity ≥Re, it is judged as not conforming to the original grade. 7.6.3 The product comprehensive grade is evaluated according to 7.4.3. Products with higher than or equal to the original grade are judged as qualified; otherwise it is judged as unqualified. 8  Marks, packaging, transportation and storage  8.1 Marks The product name, specification, grade, batch number, net weight, gross weight, package quantity, package date, product standard number, label, manufacturing enterprise name, detailed address and other relevant information as well as the moisture proof mark and fragile mark shall be indicated on the packaging box. 8.2 Packaging 8.2.1 Each package shall be covered with a plastic bag and put in the packaging box. Locating devices (locators or locating hole panels etc.) shall be equipped inside the packaging box to fix the package. The quality of the package shall protect it from damage. 8.2.2 Packages in each packaging box shall be of identical size to the greatest extent. Products of different types, specifications, batch numbers and grades shall be separately packed in different boxes. Mixed packaging is strictly prohibited. 8.2.3 Each batch of products shall be accompanied by quality inspection certificate. 8.3 Transportation Damaging or moisturizing the packaging box during transportation is prohibited. 8.4 Storage The packaging box shall be placed in batches in dry, clean and well-ventilated places. .......
