The main items of non-woven quality inspection

Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, and price Low-cost, recyclable and other characteristics. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties.


Non-woven fabrics are made of chemical fibers and plant fibers on a wet or dry papermaking machine under the condition of water or air as the suspension medium. Although it is a cloth and is not woven, it is called non-woven. cloth. Non-woven fabric is a new generation of environmentally friendly materials, which has the advantages of good strength, breathable and waterproof, environmental protection, flexibility, non-toxic and tasteless, and low price. It is a new generation of environmentally friendly materials with the characteristics of water repellency, breathability, flexibility, non-combustibility, non-toxic, non-irritating, and rich colors.


Non-woven fabric has no warp and weft threads, it is very convenient to cut and sew, and it is light in weight and easy to shape, which is very popular among craft lovers.


Color fastness test: color fastness to washing, color fastness to rubbing (dry and wet), color fastness to water, color fastness to saliva, color fastness to light, color fastness to dry cleaning, color fastness to perspiration Test of physical properties: tensile breaking strength, tearing strength, seam slippage, color fastness to dry heat, color fastness to heat pressure, color fastness to chlorine water, color fastness to scrubbing, color fastness to chlorine bleaching , Seam strength, burst strength, pilling resistance, abrasion resistance, fabric density, weight, thickness, width, weft, yarn count, moisture regain, single yarn strength, appearance after washing, dimensional stability Sex


Functional testing: air permeability, moisture permeability, combustion performance, waterproof performance (hydrostatic pressure, splashing water, rain), electrostatic testing


Chemical performance testing: PH value determination, composition analysis, formaldehyde content, azo test, heavy metals.
