#Seacell #seaweed #seacellfibre #textilecoach #fibres Seaweed is a versatile and sustainable material that is increasingly being used in textiles. Seaweed fibres are an eco-friendly alternative to traditional textiles like cotton and polyester, which are environmentally damaging and unsustainable. Seaweed textile production has been around for centuries in Japan, but in recent years, it has gained popularity in the West as consumers become more environmentally conscious. In t

#Textiles #CarbonFiber #TextileCoach Introduction: Carbon fibre, also termed “CF, “ is about 5-10 micrometres in diameter and is composed of 90 % carbon atoms in its mass. This fibre is produced by the carbonization of organic fibres. CF has various advantages like Low weight, High Strength, chemical resistance, high stiffness, low thermal expansion, and high-temperature resistance. Due to the above properties, CF has various applications like Military applications, Aerospac

#Wool #Textile #TextileCoach #Gate #Tf_Gate #FiberLength WOOL FIBRE LENGTH (Capacitance Method) WIRA fibre diagram machine: (length for combed wool fibre) Parallel fibres have one end sealed between strips of plastic. Measurement is carried out by pulling the fibres “draw” through measuring slots. M/c measures the capacitance as the ‘draw’ passes through slots. (capacitance is proportional to the amount of material) Measured Length is calculated from the ten-length reading ta

#Textile #Yarn #Crimp #Gate #TextileCoach Crimp: Due to the interlacement of warp and weft yarns, a certain amount of waviness is imparted to the warp and weft yarns in a fabric. This waviness is called crimp. Hence the apparent length of a thread as it exists in the fabric is less than its straightened length. Crimp Percentage: It is defined as the mean difference between the straightened thread length and the distance between the ends of the thread while in the cloth, expre

#Textile #Gate #Fabric #Fashion #GSM #FabricWeight #TextileCoach GSM| Fabric Weight: The weight of a fabric can be described in the following two ways: Weight per unit area in terms of ounces per square yard or grams per square meter. Weight per unit length in terms of ounce per yard or grams per meter. The weight of a fabric can be determined by one of the following three methods: Method 1: Weighing of an entire cut, roll or bale of fabric when the length and width of the fa

Polymer: A polymer is defined as the repeating unit of a chemical.

#Gate #Tf_Gate #Textile #TextileFibers #TextileCoach Natural fibers have their own peculiar structures, spots, lines, and other marks that help in identifying them. Following are some examples of natural fibers and how they look like under a microscope: Cotton: The cotton fiber may be a single elongated cell. Below a magnifier, it's like flat, spirally twisted ribbon like tube with rough granular surface. However, mercerized cotton does not have natural twist. The finishing m
