Abstract

The invention discloses high-elasticity disposable non-woven fabric underpants which comprise an underpants body prepared from melt-blown non-woven fabric, and the melt-blown non-woven fabric is prepared from the following raw materials in parts by weight: 40-65 parts of modified polyethylene glycol terephthalate; 15-25 parts of polypropylene; 10-28 parts of polyether type polyurethane; 2-8 parts of calcium carbonate powder; 2-5 parts of a compatilizer; the invention further discloses a preparation method of the high-elasticity disposable non-woven fabric underpants. The high-elasticity disposable non-woven fabric underpants are prepared by cutting and gluing the melt-blown non-woven fabric prepared from the raw materials. By the adoption of the technical scheme, the disposable non-woven fabric underpants have the effect of being good in elasticity.

Description

technical field [0001] The present application relates to the field of nonwoven products, in particular to a high-elastic disposable nonwoven underpants and a preparation method thereof. Background technique [0002] Non-woven fabric refers to a cloth-like product made of chemical fiber as the basic raw material and bonded chemically or hot-melt. Non-woven fabrics directly use polymer masterbatches, short fibers or filaments to form fibers through airflow or machinery, then undergo spunlace, meltblown, spunbond, etc., and finally finish the non-woven fabric formed by post-finishing. It can be applied to masks, underwear, etc. in daily life. [0003] The underpants include a front panel, a back panel and a bottom shelf. When non-woven fabrics are used to prepare disposable underwear, the front panel, the back panel and the bottom shelf are connected by sewing or bonding, and then all around the opening of the disposable underwear. The rubber band is sewed, and the waist ope...
