In many cases, the quality inspection department can not give a reasonable explanation because of the problems that are not related to the product standards implemented in the product.

Therefore, the standard should formulate corresponding examination items according to the problems in the process of wearing clothes.

The following are some suggestions made in this paper according to some problems appearing in clothing and the lack of relevant inspection items in the corresponding execution standards.

1 wear and tear of pure cotton casual wear

Natural fiber now

Fabric

Favored by consumers, many garments are made of pure cotton, such as cotton casual pants or casual shirts.

Most of these products carry out FZ/T 81007 - 2003 "single and clipped garments" standard, which only stipulated the internal quality items such as dimensional change rate after washing, dimensional change rate after dry cleaning, fiber content, peel strength of adhesive lining, color fastness, pilling, cracking, formaldehyde content and pH value.

However, wear resistance is one of the main properties of clothing, and quality inspection departments can not determine the quality of clothing according to this standard.

The existing standard is only FZ/T81006 – 2007 "jeans" has wear-resistant performance indicators, stipulates the number of wear, therefore, it is recommended that such wear standards should be increased in the assessment of wear resistance indicators.

2 slippage of lightweight and loose structure clothing

Slippage is

clothing

As one of the common inspection items in product standards, take the standard of FZ/T 81007 - 2003 "single and clipped garments" as an example. The item in the standard specifies that the fabric with weight less than 50 g under silk fabric and square meters shall be carried out according to GB/T18132 standard, and other fabrics shall be carried out according to this standard.

However, in actual tests, some square meters weighing more than 50g, but not lightweight fabrics of silk fabrics, and the loose structure fabrics with the conditions conformed to the test results, most of them failed to pass the test, resulting in unqualified products.

In fact, these two kinds of surfaces are often made into loose clothing. Generally, there will be no slippage in the wearing process. But according to this standard, it is unreasonable for most of the enterprises to check that most of the products are unqualified.

Therefore, it is necessary to categorize the standards for such problems. Light weight and loose structure products should be relaxed compared with ordinary fabrics.

3 thermal insulation and down weight of down jacket

The down jacket is the clothing that people wear for warmth in winter, so warmth retention should be an important index to measure whether the down jacket is warm or not.

The thermal insulation of down jacket is related to the amount of filling, the amount of cashmere and the thickness of the fabric, especially the amount of filling.

The filling temperature is 1 centigrade per 5 g, and the most comfortable temperature that the human body can feel is 32 degrees. However, because the down garment does not directly contact with the skin, the temperature inside the down jacket reaches 25 degrees, which is the most comfortable temperature.

If the thermal conductivity of the 5 g down garment is measured at 1W/m. C, the filling temperature of an adult short down jacket will reach 125 g to meet the most comfortable temperature standard of the highest 25 centigrade.

Nowadays, the price of down coats is not bad, but the number of fleece is less and less. The long feather down clothing sold on the market is only about 100 g, which is far from being able to keep warm.

GB/T14272 - 2002 "down garment" standard only stipulates the deviation of filling amount, and does not stipulate the filling amount of a single down garment.

Because there are many styles of down jacket, such as adult, children, long, short, and so on, the standard does not stipulate the specific amount of filling. Therefore, this article suggests whether we can directly assess the index of warmth retention to ensure the thermal insulation of down garments.

People also pay attention to the purchase of down garments in addition to the warmth.

fashion

Therefore, the down jacket fabric has been constantly innovated to cater to the consumer's psychology, but if the down coat is duffed, it will be very unpleasant.

But GB/T14272 - 2002 "down garments" has no assessment of the pile.

In 2009, there were two new standards for drilling test methods, namely, GB/T12705.1 - 2009, test methods for anti weave properties of textile fabrics first parts: friction method and GB/T12705.2 2009 2009 test methods for textile fabric anti drilling property: part second: rotary box method.

The two methods are mainly to test the fabric's performance of anti fleece. The test method is to make a sample bag with an effective size of 170 mm * 120 mm. The sample bag is stitched around the suture, the bag is filled with eiderdown, and the adhesive bags are used to sew the suture seam of the sample bag to test.

But in the process of wearing down clothes, the down is mostly from the stitch part of sewing. Generally, if the fabric is too thin, the fabric itself will not be duffed.

Therefore, the test method of this standard is different from the wearing process, and is of little significance in assessing and measuring whether or not the down garment is in velvet.

4 cracking of coated fabrics

The coating fabric has its own characteristics and disadvantages. During the wearing process, the problems such as fading, washing, cracking and so on are easy to appear.

Cracking of coated garments is a very painful problem for consumers.

For inspection institutions, the existing coating clothing standards are few. GB/T23317 - 2009 "coating clothing moisture resistance technical requirements" standard has the coating adhesive strength (wet state) index assessment, but the coating process cracking is different from the standard coating coating strength (wet state) index.

The adhesive strength (wet state) index of the coating is mainly manifested as whether the coating is degumming, foaming, not cracking under wet condition.

The coated fabric has a certain brittleness at a lower temperature and easy to crack. Therefore, it should be assessed that the strength or wear resistance of the coating at a certain low temperature is more close to the state of the wear process.

In addition, there will be some aging phenomena of the coated fabrics over time and washing times. In this regard, assessment indicators should also be established.

Clothing in the process of wearing a series of activities and changes in the environment of the place, the situation is more complex, prone to some problems, the standard is more conventional indicators, such as fiber content, color fastness, strength, pilling, safety indicators, etc., in order to better solve.

clothing

In the wearing of various problems, the corresponding product standards should be related to easy assessment indicators, so that the quality inspection departments also have the basis to solve practical problems for consumers, and give consumers a satisfactory answer.
