People's net, beijing, march 14 (journalist joe j. J.), has evolved to become a fashionable single product for many lovers. How do you choose the material for the wig? Does it hurt to wear it often? To that end, the shanghai market protection commission has recently purchased 40 wig products for testing, 21 of which were issued and 19 of which were issued through network electrician platforms, physical store platforms, etc。
The prices of 40 wig samples ranged from $99 to $6534. In this comparative experiment, the shanghai city institute for quality control and inspection commissioned the testing of the wear performance of wig samples by reference to a number of criteria, which are not covered by the current standards, but which are of particular concern to consumers in the selection of wigs。
The results of the tests showed that 25 samples were found to contain alkylphenol (ap) and alkyl polyoxyethylene ether (apeo), substances harmful to organisms, of which 9 samples contained concentrations exceeding 100 mg/kg. In response, the shanghai commission recommended that consumers should first focus on the quality and safety of products when selecting wigs。
The higher the hair, the more expensive
The material of the wig is the primary consideration for consumers when choosing to buy the wig。
There are currently three main types of wig material on the market: full hair (i. E. 100 per cent of hair fibre), fibre-fibre (i. E. 100 per cent of polyester fibre) and mixed hair (i. E. Hair + polyester fibre). These three types of wigs vary in their authenticity, comfort and price。
The material marking of the wig sample was checked in this comparison experiment, with 33 of the 40 wig samples marked with material information, while 7 samples were not marked with material information, and partial samples were marked with incomplete information and unclear material ratios. For example, material labels such as “dumbly-hot” “imported silk pines” “remembering”。
The higher the general hair-fibre content, the higher the prices of wigs, the higher the prices. In this comparison sample, the price of the whole hair sample was more than $1,000, and the value of mixed hair and fibre-fibre hair was more than $500. Failure to accurately mark the composition and proportion of materials can easily lead to misunderstandings among consumers when selecting purchases。
In addition, a test of the material of the wig sample found that a copy of the wig, purportedly distributed by hangzhou chiwi trading ltd. And produced by the golden hua city dream wig co. Ltd., claimed to be real hairline and actually mixed hair。
Full hair and a much higher hair-fibre wig. It's better to breathe
Consumers have indicated that wigs are worn for long periods of time, and they are not airy and their heads are itching. The wear performance of wig samples was also tested in this comparative experiment。
Factors such as the condensity of the hairline, the bottom of the net, the thickness of the hair and the material all affect its permeability. The substrates of the product network, the density of hair hooks, and the thickness of silk materials make the permeability worse. Because the hair (hairs) type product is partially wearing a wig, the comparison test is only for an air-transformation test for 21 hair-release samples, the higher the amount of air-refruit, the better the air-refruit and the better the comfort。
From the results of the tests, all hair and wig samples with higher hair fibres were better ventilated and less ventilated。
This comparison test tested the combustion performance of 14 mixed and 9 fibre-cream samples containing fibre-optic components. Four samples tested did not rekindle and the expert assessment found that the samples had been flame-retarded during the production process; the remaining 19 samples were rekindled, melted and caused defaminized cotton burning. From the results of the tests, wigs containing fibre-optic components, without flame retardation treatment, are more rapid and intense in combustion processes, with a persistent high number of melting droplets, prone to secondary combustion, and some safety risks。
25 samples detected hazardous substances
In terms of safety performance, alkylphenol and alkyl polyoxyethylene ether have been included as safety indicators in this comparison test to detect whether the wig product has left any restricted substances harmful to human health。
This comparative experiment tested wig samples against indicators from relevant textile standards. Of the 40 wig samples tested, 15 did not detect the hazardous substance; 16 sampled it contained less than 100 mg/kg; and 9 sampled the hazardous substance in excess of 100 mg/kg, in which a wig sample (referred to as nayoo) that had been produced by xu chang ess products ltd. Was measured at 448. 79 mg/kg。
In addition, the comparison test was conducted on the issue of the actual material content of concern to consumers. As there is currently no standard for testing the actual material content of wig products in our country, the comparison test found suspected animal hair fibre composition in some of the wig samples by contrasting optical microscopes to the horizontal and vertical morphological characteristics of human fibre。
