Fabric weight: The "weight" of textiles refers to the unit of measurement in grams under a standard unit of measurement.
For example, the weight of a square meter cloth is 200 grams, expressed as: 200G/M2, etc. The 'gram weight' of a textile is a unit of weight.
Eight main reasons for insufficient fabric weight:
① When purchasing the original yarn, the yarn was too thin, for example, the actual measurement of 40 yarns was only 41 yarns.
② Insufficient moisture regain. The fabric that has undergone printing and dyeing processing loses a lot of moisture during drying, and the specification of the fabric refers to the weight in grams at the standard moisture regain. So, when the weather is dry and the dried cloth does not fully regain moisture, the weight will also be insufficient, especially for natural fibers such as cotton, hemp, silk, and wool, which will have a significant deviation.
③ The original yarn wears heavily during the weaving process, which can lead to excessive shedding of hairiness, resulting in the yarn becoming finer and resulting in lower weight.
④ During the dyeing process, re dyeing can lead to significant yarn loss and result in yarn thinning.
⑤ During the singeing process, excessive singeing power causes the fabric to become too dry, and the yarn is damaged during desizing, resulting in thinning.
⑥ Caustic soda damage to yarn during mercerization.
⑦ Scratching and sanding can cause damage to the fabric surface.
⑧ Finally, the density did not meet the process requirements. Not producing according to specifications, insufficient weft density and warp density.
