Disposable Non-woven Fabric Use in the industry

We have been talking about non-woven use of the issue about its scope of use, etc., but we are talking about one aspect, that is, the use of greenhouses greenhouse insulation and related conservation Some projects in the type of use in these areas seems to prove that there is no problem and drawbacks, then, is not that non-woven no problem? In actual fact, non-woven production will appear what problems?

Today, we focus on the use of non-woven fabrics in the textile industry, in the textile spinning process, the need for cooling air evenly cooling, in the process, the need to use non-woven products to ventilation; before we Uniformity of the non-woven fabric has not been discussed, not in the insulation will be used, but in the cooling process, its uniformity is indeed very important, if the product is less than the standard of uniformity, then , It will cause serious parallel wire phenomenon, affecting the normal production, resulting in economic losses.

Uniformity does not mean that there is no requirement for non-woven fabrics in every industry. However, as the use of non-woven fabrics becomes more and more widespread, the corresponding standards will become stronger and stronger. If we are in Greenhouse insulation also need to use uniformity standards, presumably after the inevitable. 1, feel visual method: This method is suitable for non-woven fabrics were scattered fiber state raw materials.

(1) Cotton fibers are shorter and thinner than those of ramie fibers and other hemp fibers, often with various impurities and defects.

(2), hemp fiber feel thicker.

(3) Wool fiber is curly and elastic.

(4), silk is a filament, long and slender, with a special luster.

(5), chemical fibers, only the viscose fiber dry, wet strength difference is big.

(6), spandex yarn has a very large elasticity, its length can be stretched to more than five times at room temperature.

2, microscopic observation method: According to the fiber's longitudinal, cross-sectional morphology to identify non-woven fibers.

(1), cotton fiber: cross-section morphology: waist circle, with waist; vertical form: flat ribbon, natural twist.

(2), hemp (ramie, linen, jute) Fiber: cross-section morphology: lumbar or polygonal, with cavity; longitudinal morphology: a cross section, vertical stripes.

(3), wool fiber: cross-section morphology: round or nearly circular, some have hair; longitudinal morphology: surface scales.

(4), rabbit hair fiber: cross-sectional morphology: dumbbell type, with hair; longitudinal morphology: scales on the surface.

(5), silk fiber: cross-section morphology: irregular triangle; longitudinal morphology: smooth and straight, vertical stripes.
