Black hearted cotton is the common name for poor quality domestic flocculent fiber products. So how much do you know about black hearted cotton? The following is organized by me about what is black cotton, I hope you like!

What is black hearted cotton

"Black hearted cotton" is the common name for poor quality living with flocculent fiber products. General life with flocculent fiber products *** quilt, mattresses, pillows, cotton clothing, etc. *** does not meet the national standard GB18383-2007 in Article 4.1, Article 4.2 requirements, it can be identified as poor quality life with flocculent fiber products.

The basic characteristics of black cotton

Black cotton is poor quality flocculent fiber products, with the following characteristics:

1, dull white and no luster.

2, feel no elasticity.

3, not smooth, easy to stick clothing.

4, hands pulling the bundle of fiber breaks neatly, fiber strength is very low.

5, there is a chemical bleaching treatment has an odor.

The bleached "black cotton" is very harmful to the human body. It not only destroys the wax layer of the cotton fiber epidermis, and the fiber cavity and cell wall also absorbed a large number of chemicals, direct contact with the human body will cause itching, allergies, respiratory distress and other symptoms, long-term use will make people sick.

How to identify black cotton

Misunderstanding

Consumers identify a flocculent fiber products *** including bedding *** with or without black cotton, the first step is to get out of the following three misunderstandings:

1, that the flocculent filler color is not black cotton is not black cotton;

2, that the flocculent filler hygiene is not black cotton;

3, that the flocculent filler health is not black cotton;

2, that the flocculent filler health;

2, that the flocculent filler is not black cotton.

3, gullible flocculent fiber products manufacturers of all kinds of publicity.

A few flocculent fiber products manufacturers in order to promote their products, often claiming that their products have received XX certification mark or mark of excellence, in line with the XX industry standards, the country's many counterparts in the implementation of this industry standard, etc., consumers must be cautious in the face of such publicity. The industry standard mentioned here is the light industry standard promulgated and implemented in 1999, the standard for flocculent filler did not make detailed provisions; and the national standard promulgated in 2001 for flocculent filler but put forward strict requirements. In order to achieve the purpose of reducing production cost, a few enterprises, totally disregarding the interests of consumers, deliberately avoid the strict national standards and only implement the general industry standards. As consumers do not understand the situation, so it is very easy to be deceived, the result is often spend a high price but buy poor quality products.

The principle of identification

The most important determining principle of identification of black cotton is: look at the product filler whether the use of banned raw materials. Used is bound to be black cotton, not used may not be black cotton. So what are the prohibited raw materials? GB18383-2001 "General Technical Requirements for Flocculent Fiber Products" supporting the provisions of the "Flocculent Fiber Products Prohibited Use of Raw Materials Management Measures" in the list of the following four kinds of substances for the prohibition of raw materials:

1, fiber industrial scraps

Fiber processing, garment processing, processing of other fiber products in the scraps. Including cotton short staple, infertile seed recycled cotton, floor cotton, waste yarn, trimmings and so on.

2, medical fiber waste

Medical institutions used, should not be reused again and again all kinds of fiber products. Including: has been used in the degreasing cotton, degreasing gauze and other medical dressings, should be eliminated from the patient's clothing, flocculation with fiber products and other fiber products.

3, regeneration of fibrous material

Industrial scraps, recycled waste clothing and other waste fiber products, such as shredding, loosening, rinsing and other ways of simple processing of flocculent fiber material.

4, used clothing and waste fiber products

Due to the use of wear or stored for a certain period of time after the loss or reduction of the original value of the use of clothing flocculent fiber products and other fiber products were eliminated, discarded.

Recognition

1, eye view. Generally speaking, "black cotton" looks less smooth, some rough, and high-quality cotton color white.

2, feel. Normal cotton feel softer, with a certain degree of elasticity, feel good, and "black cotton" looks impurities, feel rough.

3, tear. By tearing, consumers can feel the strength of the cotton how, in general, "black cotton" a tear on the break.

4, flavor. If the use of chemical fibers of cotton tires, raw materials should be produced by the chemical fiber factory, rather than rotten cloth, industrial waste into the chemical fiber. Normal chemical fiber is generally uniform in color, a certain length, without too much dust, better elasticity, no odor, otherwise that is shoddy products.

5, color. If the cotton wool color miscellaneous, and even contains yarn and rags, it is likely to be used for industrial waste produced by secondary processing of poor quality products.

6, burning. "Black cotton" in the processing of bleaching program, smell will have a faint sour taste. High-quality cotton burning without pungent odor, while the "black cotton" is obvious pungent odor.

The main hazards of black cotton

The main products of black cotton are concentrated in cotton, pillows, quilts, cushions, etc. At present, there are a large number of media reports on the abuse of black cotton car seat cushion manufacturers, the domestic 22 urban consumer *** units have jointly released a consumer alert, alert "black cotton" car seat cushion into a "hidden killer. The invisible killer.

Wide range

From the geographical point of view, Chongqing, Jiangsu, Shandong, Tianjin, Shanghai, Jinan and dozens of cities have reported that there are black cotton cushions. According to media reports around the world, various automotive stores have black cotton cushions for sale, and according to media surveys, seven or eight hundred dollars below the car cushion basically have black cotton.

Online shopping is worrying

According to the automobile enthusiasts association volunteers in the network shopping on the sample survey shows that the network currently summer cushions using black cotton may be more than 95%. In the 18 sets of car cushions purchased by volunteers, only one summer car cushion purchased in an online store without the discovery of black cotton, the remaining 17 sets are using black cotton.

The main hazards of black cotton are the excessive short lint and the adulteration of industrial waste in the raw materials.

Short lint refers to the length of not more than 16 millimeters of fiber cotton, because of its small size, light weight, it is easy to penetrate the fabric of cotton products floating in the air, inhaled by the human body may be induced by asthma, respiratory and other diseases; industrial waste refers to textile factories, garment factories in the production process of the leftover scraps.

In addition, the old clothes, used cotton tires and other household garbage processed out of the "recycled cotton wool" is generally included in the ranks of industrial waste. Such poor-quality cotton products due to the lack of strict sterilization, is likely to become a bacterial "hotbed", the human panel contact will be subjected to varying degrees of ***, light red spots, feel itchy, heavy will lead to psoriasis and other panels of the stubborn disease, and even produce a poisonous reaction....
