In the clothing, in the process of actual production and use of down jacket cloth with soft nap of leakage has been plagued by clothing manufacturing enterprises and consumers.Our country clothing standard GB/T 14272-14272 "clothing" and there is no detail about the velvet leakage testing requirements, this will directly lead to leakage in the event of a clothing cloth with soft nap, there to determine the corresponding test methods and indexes to assess, clothing of wool leakage situation has become urgent.
1. The clothing fabric drilling pile test method
Refers to prevent drilling pile properties of the fabric down or feathers from the performance of the yarn gap between drilling leakage in the provisions under the condition of drilling pile number said.Refer to relevant domestic or foreign some information for the inspection of down and feather of drilling pile fabric performance basically has the following three kinds of test method.
1.1. Drilling pile physical test
Mainly include the friction test and impact test calculation out the number of down and feather, feather oozy fabric as assessment down drilling pile fabric performance rating according to the specific circumstances of the following friction test in the human body wearing clothing and irregular movement in the process of friction, extrusion machine set to turn to a certain number of observation to drill a number of cloth cover down or feathers.
2. The impact test
Make sample of bag or cylinder is installed within a certain quality of feather on the testing machine with hard rubber ball slewing through rotary box in the constant speed rotation will impact in the rubber ball to a certain height of sample to simulate feather products in taking all kinds of extrusion, kneading, collision, and so on.After continuously until the specified number of collision from inside the sample by counting the number of the drill down to drilling pile properties of fabric.The main test methods have EN?12132.2-1995?The feather down? Impact test drilling pile test method of fabric and GB/T?12705-1991?The fabric drilling pile test method.
1.2. Air permeability test
By testing the rate of airflow through the fabric of drilling pile method to evaluate material properties.This is a good indicative test id number is lower that the smaller the possibility of leakage.Usually permeability test index is less than 108197 mm/s is considered to drilling pile.Yet some fabrics, pass the permeability test but can pass the drilling pile physical test.Standard test method at home and abroad are mainly EN ISO 9237 "the determination of textile fabric permeability" GB/T 5453-1997 "the determination of textile fabric air permeability of the feather, feather drilling pile has yet to officially request finite.
1.3. The fabric density test
For feather products detection of fabric density requirements is the most common.Usually the higher fabric density drilling pile, the better.However yarn thickness, and some textile technology factors also makes some of the high density material use effect is not satisfactory on the feather products and some low density material would be more appropriate.The general as clothing production enterprise internal control indicators.Clothing in the process of actual wearing into consideration and consistent with the actual situation of sexual recommended physical test methods of impact test specific assessment indicators can be reference to the general international requirements.
2. The production process such as the effect on the performance of clothing drilling pile
The above test method for performance of drilling pile fabric itself without including may in the process of clothing production and processing such as suture, pinhole and other factors.I center in feather clothing inspection and handling customer complaints problems found in the process of clothing a good portion of pile leakage occurred in stitching the pinhole in the pocket or in a pocket cloth is used generally drilling pile fabric performance is poor.After a long period of testing and summary suggested in the immanent quality of clothing requirements increase appearance after wash test project and as a standard in mandatory testing project.Considering the dry cleaner has destructive effect to feather oil thus affect the characteristics of the feather general dry cleaning is not recommended to wash after wearing it is advisable to now only the inspection clothing after wash appearance.Specific test methods selection of GB/T 8629-2001 "household cleaning and drying process is used textile test" 5 a program of continuous washing five times or more than five times after tumble turn dry and pocket watch clothing surface drill down to the root of the number.Before the test started to appear in the down jacket on the rid all hairs are including in the pocket.Test result judgment is mainly based on the following the provisions of the feather, feather out in 10 below the root, the number of fabric material under 15 root namely as "acceptable" or as "unacceptable".And indicate the drilling pile phenomenon occurring in the test report of the specific parts and drill down to the root of the number so that enterprises find the root cause of the problem is to better serve the production.Clothing's appearance after wash test as clothing production enterprise determine clothing fabrics after plans to produce a final check before to assess when processing down jacket chooses stitches, the rationality of the stitching and sewing process.
3. The conclusion.
In the assessment of clothing advice on the one hand, by the impact drilling pile performance test to the inspection of clothing fabric drilling concrete pile performance appraisal indicators can consult the general international standards on the other hand, through the test clothing appearance after wash whether to accept to assessment of clothing production and processing technology of reducing clothing production in velvet leakage problems.
