Solar rays can be roughly divided into visible light and invisible light. Visible light refracts the light (spectrum) of purple, blue, green, green, yellow, orange and red through the prism. The light outside the red light is called infrared light, or infrared light, when the wavelength in the spectrum ranges from 0.75 to 1000 microns. Infrared ray belongs to the category of electromagnetic wave and is an electromagnetic wave with strong thermal effect. The wavelength range of infrared rays is very wide. People divide infrared rays in different wavelength ranges into near infrared, mid-infrared and far infrared regions. Electromagnetic waves with corresponding wavelengths are called near infrared, mid-infrared and far infrared.

Different textile materials have different moisture content and moisture regain due to different internal structures. According to GB/T9995 and other standards, the sample is exposed to flowing air heated to the specified temperature in an oven until the sample reaches constant weight. The total mass loss during drying is taken as the weight of water. FFZ382 fully automatic ventilated fast constant temperature oven can reproduce the test environment specified in the standard, and automatically weigh the changes of sample quality in different stages through a high-precision weighing system, so as to detect the moisture content and moisture regain of the sample.

Subject: Assessment of Appearance Changes of Various Clothing Fabrics After Dry Cleaning In daily life, we often encounter various changes after clothes are dry cleaned, such as shrinking of clothes, bigger and bigger washing of clothes, fading of clothes, wrinkles or cracking of clothes, etc., which bring us a lot of inconvenience in life. After the YG6A dry cleaning tester heats or directly dry cleans the sample with tetrachloroethylene solvent, the standard sample photos are used to evaluate the appearance change grade of the sample, and the dimensional stability of the adhesive lining and the clothing fabric is measured.

The 2018 China International Textile Machinery Exhibition and ITMA Asia Exhibition will be held in the National Convention and Exhibition Center (Shanghai) from October 15 to 19, 2018. All textile professionals are warmly welcome to come and talk about the textile future. Booth number: H5F29; Address: No. 168 Yinggang East Road, Qingpu District, Shanghai; Contact: Chen Jiajun (13858850510)

As an essential carrier for people to travel, luggage is often damaged to different degrees by falling, falling, touching and bumping during use and handling. Damage at different parts will affect the use of luggage. The luggage falling instrument is a testing method according to the standard GB/T29212007: the luggage with a specified weight is placed at a specified height and then allowed to fall naturally, causing the luggage to generate shock and vibration. The intact degree and the strength of the overall structure of the box body, the box opening, the fixing parts, the connecting parts, the pull rods, the running wheels, the wheel shafts, the wheel frames, the locks and other parts of the luggage are inspected.
