Scope of FZ/T 73013-2017 Knitted Swimwear
FZ/T 73013-2017 standard specifies the product classification, model, requirements, experimental methods, judgment rules, product instructions, packaging, transportation and storage of knitted swimwear.
The standard is applicable to the identification of the quality of knitted swimwear products made of knitted fabrics. Swimsuits made of other textile fabrics can be referred to.
Product classification and model
1. Knitted swimwear is divided into three types: one-piece swimwear, split swimwear and swimwear.
2. Model of one-piece swimsuit: mark the net height and chest circumference in cm.
3. Split swimwear shall be marked with the net height, chest and hip circumference in cm. Among them, the split swimsuit jacket with cup shall comply with FZ/T 73012.
4. The net height and hip circumference of the swimsuit shall be marked in cm.

2. Internal quality:
The project content includes fiber content, formaldehyde content, PH value, odor, decomposable carcinogenic aromatic amine dye, tensile elastic elongation, tensile elastic recovery rate resistant to chlorinated water (swimming pool water), color fastness/grade (soaping resistance, sweat resistance, water resistance, seawater resistance, friction resistance, light resistance, splicing mutual dyeing degree).
3. Appearance quality requirements:
The content includes the provisions on surface defect evaluation, defect category, yarn defect (oil yarn, colored yarn), weaving defect (long stitch, repair mark, silk stretch, loose stitch), dyeing and finishing defect (color difference, grain skew, aurora print, rust stain), sewing defect (sewing greasy thread, needle hole, heavy stitch), printing defect (sand hole, dry plate, missing pattern, incorrect set, overlapping color, and shading).
4. Size deviation:
