From the perspective of different swimsuit safety performance indicators
Knitted swimsuit is made of knitted fabric suitable for wearing clothes while swimming, also used for Beach leisure, rowing and other water sports. Knitted swimwear can be divided into one-piece swimwear, bathing suits and swimming trunks three types. One-piece swimwear-main tube and harnesses, split swimwear mainly skirts, high waist and bikini type and so on.
Currently the main standards of quality and safety of domestic knitted swimwear involved GB 5296. 4-2012 consumer product instructions for use-part 4: instructions for use on textiles and clothing, GB 18401-2010 National textile product basic safety specifications, and GB/T 22852-2009 and FZ/T 73013-2010 of the knitted swimwear fabrics of the knitted swimwear.
These safety standards from different angles the knitted swimwear are specifications and requirements, performance indicators the main specification for fiber content, stretch elastic elongation and resistance to chlorinated water (swimming pool) tensile elastic recovery.
Fiber content refers to the clothing material of fiber types and proportions of various types, such as 80%/20% nylon spandex, it affects the wear comfort swimsuit, washing and maintenance, is to determine the swimsuit using one of the important indicators of performance.
Stretch elastic elongation is under the prescribed loading swimwear fabric stretched the length of a percentage of the original length, is an important index to evaluate whether the swimsuit wear comfortable, elongation of small bathing suit wearing tight, easy to cause human discomfort.
Chlorinated water (swimming pool) evaluation of tensile elastic recovery is swimming in deformation response level after use, resistant to chlorinated water (swimming pool) tensile elastic recovery after bad bathing suit easier to wear serious deformation, elasticity loss, lose value continue to wear.
In terms of safety indicators provide formaldehyde content, pH value, color fastness, decomposition of carcinogenic aromatic amines dye concentration requirements.
Formaldehyde is a colourless, pungent odor and organic matter soluble in water, color fastness of textiles in resin and are used during processing. GB 18401-2010 baby products (class a), with direct contact to skin product (category b), without direct contact to skin product (category c) classification was carried out after a limited category a 20mg/kg class b (75mg/kg, type c (300mg/kg, and European directives and current control system of international standards are basically the same.
PH value is check fabric is an indicator of acidity, because human skin has a weak acidity (pH values between 5.0-5.6 of the healthy skin). GB 18401-2010 provides direct contact to skin product pH value of 4. 0-8.5 in the products without direct contact to skin pH value 4. 0--'9. 0, out of range are not qualified, is to ensure the safety of the product. Both the European Union and the European States currently have corresponding provisions, limited as mandatory standards, stricter than EU legislation.
Mainly check for colour fastness the fastness of the dye on the fiber and fabric, especially bathing suits after washing, the Sun, sweat, swimming pool water, or rub color change that occurs after the object.
GR 1X401-2010 reducing carcinogenic aromatic amine dyes that provides disabled for 24, with international standards, and maximum limit value for 20mg/kg, provisions stricter than the EU banned dyes carcinogenic aromatic amine concentrations in textile 30mg/kg requirement.
