Shenzhen Destroyed A Batch Of Unqualified Infants And Young Children'S Clothing Ph Value Exceeded Standard Harm.

Inspection and Quarantine Bureau in a number of bonded zones

Imported infant with unqualified pH value

Destruction.

The batch of children's Woven cold resistant jackets totaled 630 pieces, valued at $4113.9, and the country of origin was China.

It was found that the pH value of the liquid extract was 7.6 and 8.6 when the inspection was carried out by the inspection and quarantine personnel after sampling inspection, which did not meet the requirements of category GB18401-2010 clothing, namely, infant textile products (pH value 4~7.5).

The pH value is reflected in clothing.

An index of pH.

Wearing unqualified pH textiles can cause irritation to the skin, which can cause skin irritation, irritant dermatitis or contact dermatitis.

The reasons for the unqualified pH value of garments are mainly as follows: first, the manufacturer's safety consciousness is not strong, and the fabric pH value is not detected, and the unqualified fabrics are produced. Two, the manufacturers use more chemical substances in the printing and dyeing, grinding and other stages, resulting in unacceptable pH value of clothing. Three, manufacturers are to reduce costs, ignore product quality and neglect product quality control.

According to statistics, in the first half of 2015, Shenzhen Port imported 17083 garments and 33 million 770 thousand dollars worth of goods. The inspection and quarantine department found that 2702 imported garments were not qualified, and the unqualified rate was 15.82%, up 11 percentage points over the same period.

What is the pH value? The harm of clothing pH value exceeding the standard?

The pH value is the negative value of the logarithm of the hydrogen ion (H+) concentration in the solution.

It represents the pH of the solution.

The pH value is composed of 1 to 14. 7 shows that the solution is neutral, that is, the hydrogen ion concentration of the solution is the same as that of the hydroxide ion. Less than 7 indicates that the solution is acidic, that is, the concentration of hydrogen ion in the solution is greater than that of the hydroxide ion, and the solution has a strong oxidizing property. The greater than 7 indicates that the solution is alkaline, that is, the hydrogen ion concentration of the solution is less than that of the hydroxide ion, and the solution has very strong reducibility.

Because there are a series of acid and alkali treatment in the dyeing and finishing process of textiles, such as the mercerizing of cotton fabrics is actually concentrated alkali treatment, while bleaching is treated with weak acid. Therefore, clothing will have a certain degree of acidity and alkalinity. Therefore, it is necessary to use corresponding testing methods to express the pH value of clothing with specific values. The pH value test of textiles is based on this demand.

The pH value of the normal skin is between 5.5 and 6.5. The high pH and high pH value of the fabric will cause irritation and corrosion to the skin, cause inflammation of the skin, and cause damage to the sweat gland system and nervous system of the human body.

Fresh clothes are washed first to remove harmful substances.

At present, when people buy clothes, they mainly focus on styles, fabrics, colors and so on. Some people wear new clothes directly and wear old clothes.

Actually, this is wrong.

It is understood that in order to eliminate the pH value and formaldehyde exceed the standard, it is harmful to the human body. The national standard GB18401, the basic safety technical specification for national textile products, divides the clothing safety grade into three categories: A, B and C. Class A is for infants and young children, formaldehyde content is less than 20mg/kg; B class is for direct contact with skin, formaldehyde content is less than 75mg/kg; C is non direct contact with skin textiles, formaldehyde content is less than 300mg/kg.

The pH values of class A and B products are allowed to range from 4 to 7.5, and the pH values of C products are allowed to range from 4 to 9.

Class A, water fastness and perspiration fastness requirements are greater than or equal to 3~4 grade. Dry friction resistance and saliva color fastness are required to be more than 4 grade. Class B and C products require water resistance, sweat resistance and dry friction color fastness to be more than 3 grade. Three kinds of products require no peculiar smell.

When buying infant clothing, we must see whether the safety level is category a "infant products".

When buying other garments, you should see whether the products are marked with GB18401 class A, GB18401B class, or GB18401C class, or safety class A, safety class B, safety class C class, and wear and use according to safety grade tips.

In order to reduce the harmful substances in clothing to a minimum, people should be reminded to wash and wear new clothes first.
