Inventory Of Clothing Frequently Encountered In The Process Of Wearing

With the continuous improvement of people's living standards,

1. wear and tear of pure cotton casual wear

Nowadays, natural fiber fabrics are favored by consumers. Many garments are made of pure cotton, such as cotton casual pants or casual shirts.

Most of these products carry out the standard of FZ/T81007 - 2003 "single and clipped garments", which only stipulated the internal quality items such as the dimension change rate after washing, the dimension change rate after dry cleaning, the fiber content, the peel strength, the color fastness, the pilling, the slip, the formaldehyde content and the 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 wear has a wear resistance index, stipulates the number of wear resistance, therefore, it is recommended that such wear standards should be increased in the assessment of wear resistance indicators.

Slippage is one of the common inspection items in clothing product standard. Taking the standard of FZ/T81007 - 2003 "single and clipped garments" as an example, the item in the standard stipulates that the fabric with weight less than 50g 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.

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

If the coefficient of thermal conductivity of 5g down clothing is 1W/m / C, it is necessary to reach the most comfortable temperature standard of up to 25 degrees centigrade for a short adult down jacket, which is also recognized as the international standard of down clothing.

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 100g, which is far from being able to keep warm.

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

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.

In addition to considering the warmth of the down jacket, people also pay attention to the fashion. Therefore, the down jacket fabric is constantly innovated to cater to the consumer psychology, but if the down coat is duffed, it will be very unpleasant.

However, GB/T14272 - 2002 "down garments" has no assessment of the project.

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

The two methods are mainly to test the fabric's performance of anti fleece. The test method is to make the fabric sample bag with an effective size of 170mm * 120mm. The sample bag is stitched around the suture, the bag is filled with down, and the adhesive bag is 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 and cracking at lower temperature. Therefore, the strength or wear resistance of the coating at certain low temperature should be evaluated to be more close to the wearing 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 all kinds of clothing problems in clothing, the corresponding product standards should be involved in easy assessment indicators, so that the quality inspection departments also have the basis to solve practical problems for consumers, to give consumers a satisfactory answer.
