What is the Hydrostatic Head Tester In Fabric A. What is Hydrostatic Head? Hydrostatic Head is a way of measuring how waterproof a fabric is. The resulting measurement in millimetres relates to how high a column of water standing on the fabric would need to be before the water would penetrate the fabric. For the best fabrics results can be as high as 30,000mm, i.e. 30 metres high, before it would penetrate the fabric. B. Hydrostatic Pressure The Hydrostatic Pressure test evaluates a material’s resistance to water penetration. The test is done using a machine that replicates the downward pressure that a water column of such height would create. The machine increases the pressure of water that is pushed against the fabric until water is visible on the other side. The required level of pressure used to force water through the fabric is then converted into a measurement of how high the water column would have been. This provides the result of the Hydrostatic Head test in millimetres. C. WHAT IS A HYDROSTATIC HEAD TESTER? A Hydrostatic Head Tester is a measuring device used to measure the water penetration resistance of fabrics and seams. It provides quick and accurate results. Digital Hydrostatic Head Tester is used to testing the waterproof properties of fabrics through waterproofing work such as canvas, coated fabrics, hood fabric, tarpaulin, rain-proof fabrics and geotextile.

1. About yarn Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, or ropemaking.A generic term for yarn and thread, it is a long, thin, soft and continuous strip with a certain strength, it is made of textile fibers, including single yarns and ply yarn. 2. What is the twisting？ Fibres are arranged around an axis by means of twist. Twisting adds strength to the yarns. Twisting, in yarn and rope production, process that binds fibres or yarns together in a continuous strand, accomplished in spinning or playing operations. The direction of the twist may be to the right, described as Z twist, or to the left, described as S twist,including. 3.The following four parameters are of importance when discussing twist in yarn: A. Direction of twist B. Twist level/ Amount of twist C. Twist angle D. Twist multiplier 4. Twisting process A. Single yarn Single yarn is formed by twisting fibres or filaments in one direction. B. Ply yarn Ply yarn is made by twisting two or more single yarns together, usually by combining singles twisted in one direction with a ply twist in the opposite direction. It is stronger and more resistant to abrasion than single yarns. Twine, cord, or rope can be made with a cable twist, each twist in the opposite direction of the preceding twist (S/Z/S or Z/S/Z), or with a hawser twist, the single yarns and the first ply twist in one direction and the second ply twist in the opposite direction (S/S/Z or Z/Z/S). The number of turns per unit of length in a yarn affects the appearance and durability of fabric made from that yarn. Yarns used for soft-surfaced fabrics have less twist than those used for smooth-surfaced fabrics. Yarns made into crepe fabrics have maximum twist. 5.EXPRESSION OF TWIST Amount of twist expressed in 1) Twist Per Inch(TPI) 2) Twist Per Meter(TPM) 3) Twist Per Centemeter(TPC) TWIST FACTOR OR TWIST MULTIPLIER The twist factor or twist multiplier is a measure of twist, which accounts for the yarn radius as well as the twist level. TM=TPC√tex or TM=TPI÷√Ne 6. FACTORS AFFECTING TWIST The twist introduced in the yarn during spinning depends upon a number of factors, such as follows: A. The count of yarn to be spun B. The quality of cotton used C. The use to which the yarn is put- is the yarn meant to be used as warp yarn or weft yarn, knitting yarn or any other yarn. D. The fineness of the fibre being spun F. The softness of the fabric into which the yarn is to be converted 7. YARN TWIST In practice, yarn twist is described using three main parameters: (a) twist direction (b) twist factor or twist multiplier And (c) twist level (turns/unit length). 8. Function of twist in yarn structure: A yarn must have sufficient tensile strength to withstand the stresses of preparation and fabric manufacture. Without twist a strand of fibers has very little strength. . The main function of twist is to be bind the fibers together and help...

Discussion On Color Fastness To Rubbing Rubbing fastness refers to the resistance of the color of textiles to abrasion or staining to other textiles, is one of the most important indexes in the color fastness of textiles, that is, the degree of fading of dyed fabric after friction, which can be divided into dry and wet rubbing. Rubbing fastness plays an important role especially. The assessment is divided into 5 levels (authenticity number), of which 5 means a very high rubfastness and level 1 a very low. The color fastness to rubbing is so important, as a professional testing organization or professional inspector; we should have a deeper understanding of the color fastness to rubbing test, so that our test results are close to the true value of the sample.

First of all, let’s talk about the color fastness test to washing. The washing fastness tester is also called the color fastness to washing, or the color fastness to soaping. It is used to assess the color fade and the color of the original fabric during the soap washing process. Staining the lining. The principle of the test is to sew textile samples with one or two specified standard lining fabrics, place them in soap or soap and anhydrous carbon-sodium mixture, perform mechanical agitation under specified time and temperature conditions, and then After cleaning and drying. Use the original sample as a reference sample, and use a gray sample card or instrument to evaluate the discoloration of the sample and the staining grade of the lining fabric. Secondly, what we want to talk about is the water fastness test. The so-called water fastness is also called the water stain fastness, which is to assess the discoloration of the original fabric and the staining of the lining after the fabric is soaked in water. The principle of the test is to sew a textile sample with one or two specified standard lining fabrics, immerse it in water, squeeze out the water, and place it in the middle of the two plates of the test device under specified pressure. After a certain period of time, take it out The sample and the lining fabric are dried, the original sample is used as the reference sample, and the gray sample card or instrument is used to evaluate the discoloration of the sample and the staining grade of the lining fabric.
