Spandex is an elastic material with a good elastic stretch response, a mature process and an economical cost. Currently diapers and the first generation of incontinence pants use spandex elastic material. Take medium size menstrual pants as an example, product design, stretching multiplier difference, elastic spandex use 0.6~1.0g/ piece are reasonable. Elastic spandex price mostly 40,000~60,000 ¥/t, individual up to 90,000 ¥/t. Elastic non-woven fabric by 3~5 ¥/square meter. Such as adult underwear-type products, the amount of 0.2 square meters / piece. If compared by the same area size, spandex composite elastic material cost is lower.

Most of the current sanitary equipment uses the process of longitudinal elasticity and cannot directly use transverse elastic material. Need to redesign the panty type absorbent care products, then customize the equipment, personalized development, there is no standard modular equipment.

The wet wipes production line is said to be the processing route of the equipment that wet wipes go through in the production process. Starting from the raw material of spunlace non-woven fabric onto the machine, it goes through a series of devices such as feeding, folding, adding liquid, cutting, stacking, conveying, packing, sticking lid, conveying and boxing. The common point between fully automatic and semi-automatic wet wipe production line is at the front end, where raw materials are fed, slit, folded, liquid added, cut and stacked, all of which are generally fully automatic devices. The difference lies in the middle and back end, where the packaging, sticking caps and boxing of wet wipes are done manually, which is called semi-automatic production line. Whether it is bagged wet wipes production line or barrel wet wipes production line, there are fully automatic and semi-automatic, according to the customer's plant construction planning and production needs, choose the corresponding production equipment to form the corresponding wet wipes product line.

The same brand of pull-ups and diapers are similar in thickness. If two different brands are compared, the thickness is determined in terms of materials, generally thick cores are wood pulp and most thin cores are SAP.

Sanitary napkins are divided into three layers: surface layer, absorbent core and bottom layer. The backing of sanitary napkins is an impermeable material that retains menstrual blood in the pads to absorb the blood that flows out during a woman's menstruation.

It is generally impossible to distinguish. There is little difference between old and new machines, and the quality of diapers does not deteriorate due to long-term use of the machine. Diaper problems are caused by problems such as wear and tear of machine parts, which requires asking a professional repair person.
