Flame retardancy Test and Test Identification of Fiber

The flame retardancy test includes some of the characteristics related to whether it is easy to ignite and the ability to maintain combustion. After years of development, the flame resistance test has formed a variety of standards, as the industry is very focused on the detection project.
Flame retardant test Purpose:
    
Through the customer to provide samples of the combustion test, according to the results of the combustion of the corresponding rating, to help customers to product quality control. Flammability rating is one of the most important safety features that are essential for many certifications and are mandatory for many countries.
  
Flame retardant test is mainly used in plastics, foam, film, textile, paint, rubber, automotive interior parts, electrical and electronic products.
Flame resistance test steps:
    
Sampling → pretreatment → start adjustment fixture height, flame height, gas flow, etc. → test and record the results → corresponding to the standard level.
The flame retardancy of the material refers to the ability of the material or article to undergo flame burning under specified test conditions. It covers some of the characteristics of whether it is easy to ignite, and the ability to maintain the ability to burn. After years of development, the flame resistance test has formed a variety of standards, as the industry is very focused on the detection project.Different materials have different combustion characteristics, we are based on different materials for testing, in turn, we can also be based on different materials to identify the characteristics of combustion materials.
Depending on the chemical composition of the fiber, the combustion characteristics are also different, so that the major categories of the fiber are roughly distinguished. The combustion characteristics of several common fibers are as follows:1, cotton, linen, sticky fiber, copper ammonia fiber: near the flame: not shrink the melt; contact with the flame: quickly burn; leave the flame: continue to burn; smell: burning paper smell; residue characteristics: a small amount of gray or gray ashes.2, polypropylene fiber: near the flame: melt; contact with the flame: melting, burning; leaving the flame: continue to burn; odor: paraffin flavor; residue characteristics: gray transparent transparent beads.3, spandex fiber: near the flame: melt; contact with the flame: melting, burning; leaving the flame: from the off; odor: special flavor; residue characteristics: white gel.4, polyvinyl chloride fiber: near the flame: melt; contact with the flame: melting, burning, black smoke; leave the flame: self-extinguishing; odor: pungent odor; residue characteristics: dark brown lumps.5, vinylon fiber: near the flame: melt; contact with the flame: melting, burning; leave the flame: continue to burn, black smoke; smell: unique flavor; residue characteristics: irregular coke color hard lumps.6, silk, wool fiber: close to the flame: curly and melt; contact with the flame: curl, melting, burning; leaving the flame: slow burning sometimes self-extinguish; smell: burning hair smell; residue characteristics: loose black particles or coke shape.7, polyester fiber: near the flame: melt; contact with the flame: melting, smoke, slow burning; leave the flame: continue to burn, sometimes self-extinguish; smell: special aromatic sweet; residue characteristics: hard black beads.8, nylon fiber: near the flame: melt; contact with the flame: melting, smoke; leave the flame: from the off; smell: amino flavor; residue characteristics: hard light brown transparent beads.9, acrylic fiber: near the flame: melt; contact with the flame: melting, smoke; leave the flame: continue to burn, black smoke; smell: spicy taste; residue characteristics: black irregular beads, fragile.

Moisture Management Test Method -AATCC 195

MMT textile moisture management tester Test Method -AATCC 195 is for the measurement, evaluation and classification of liquid moisture management properties of textile fabrics. The test method produces objective measurements of liquid moisture management properties of knitted, woven and nonwoven textile fabrics. The test method produces objective measurements of liquid moisture management properties of knitted, woven, and nonwoven textile fabrics. The results obtained with this test method are based on water resistance, water repellency, and water absorption characteristics of the fabric structure, including the fabric's geometric and internal structure and the wicking characteristics of its fibers and yarns. The results obtained with this test method are based on water resistance, water repellency and water absorption characteristics of the fabric structure, including the fabric's geometric and internal structure and the wicking characteristics of its fibers and yarns.

The Leather Friction Color Fastness Tester

Leather friction color fastness tester applied to test leather property in shoes, clothing, luggage handbag industry, research laboratories; commodity inspection, arbitration and technical supervision departments.Leather friction color fastness tester test the degree of decolorization of dyeing leather after friction. It can used to test the leather color resistance to dry, wet and friction. This instrument is suitable for leather, textile, belt, trademarks, cardboard and other friction materials by foreign object damage and decoloring. The machine is designed to carry out a rub fastness test on the surface of leather or coated fabrics to determine the marring of the surface finish and to assess the amount of color transfer from the sample to the rubbing pad. This machine is designed to determining the colorfastness of leather, plastics and textile materials. The colorfastness is assessed by checking change in color of the specimen and stain of the felt after rubbing the

How Sublimation Fastness Tester Works?

Sublimation Fastness Tester is a suitable instrument for dyestuff manufacturers as well as textile processors for checking effects of dry heat on dyestuff. Qinsun-lab offers Sublimation Fastness Tester of the best quality and at the best price which gives accurate results.    Features of Sublimation Fastness Tester : Testing the effect of direct heat on the dyestuff; up to 250°C temperature range; Independent digital timers with the minimum display of 1℃(one with each of top and bottom plates, respectively); Can test entire range of temperature in a single test.                           Working Principle: A dyed cloth piece is sandwiched between two undyed pieces and placed to cover the heat pads and the test goes on for a preset time period. The fabric pieces should be picked up immediately. The undyed fabric pieces will be stained by the dyes. This gives the sublimation fastness properties for the range of temperature 130°C to 250°C in one test. A rea
