Embodiment Construction
[0029] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.
[0030] Such as figure 1 As shown, the non-woven fabric production process sequence in this example includes the following steps: material preparation, opening, dust removal, carding, cross-lapping, drafting, pre-wetting of the sandwich, spunlace, drying, drying and setting, storage Cloth winding, cutting, packaging.
[0031] 1) Material preparation: Prepare high-quality absorbent cotton or colored cotton for use in the next process.
[0032] 2) Opening: Use an opening device to open the raw material into a single fiber state. The prepared absorbent cotton or colored cotton is sent to the pre-opener through the conveyor belt for preliminary opening, and then sent to the large warehouse blender through the cotton conveying fan to fully mix various fibers of different lengths and deniers. Part of the raw material is taken out ...

Abstract
The invention discloses a production technique of pure cotton non-woven fabrics and a device. The technique comprises the following steps: cross lapping: spreading a fibre screen evenly and alternately in a reciprocating way; extending: regulating the arrangement of fibre at different extension speeds; clipping screen and prewetting: performing pre-wetting processing to the fibre screen; performing once flat-screen water thrust: snarling the fibre screen for parallel movement with water jet; performing drum water thrust: snarling the fibre screen for circular movement with water jet; and performing twice flat screen water thrust: snarling the fibre screen for parallel movement with water jet again. By adopting the production technique, the device and the water thrust process of using the manner combining the flat screen and the drum, the invention can maximize favorable factors and minimize unfavorable ones to develop respective advantages, improves the physical performances of producing ratio, product tension, evenness, flexibility and surface mass, saves materials, reduces pollution to circulating water, reduces the maintenance amount of device, prolongs the service period of the device and achieves the aim of reducing cost and saving energy.
Description
【Technical field】 [0001] The invention relates to a production process and equipment of non-woven fabrics. 【Background technique】 [0002] The raw materials of non-woven fabrics are mainly synthetic fibers and cotton. Synthetic fiber non-woven fabrics have non-renewable raw material resources, high production costs, high destruction costs, and are not environmentally friendly, so their applications are not widely used. The raw material of pure cotton non-woven fabric is natural cotton, which has sufficient raw materials, convenient handling, no allergic reaction to human body, and natural biodegradation. Moreover, pure cotton non-woven fabric has high hygroscopicity and air permeability, high strength, No fluff, no hair shedding, good drapability, good hand feeling, no chemical adhesives and other impurities, so it is widely used, such as: women's sanitary napkins, sanitary pads, baby diapers, cotton pads, beauty masks, etc. product. However, at present, the production tec...
