Problems solved by technology

[0003] At present, the hot-air nonwoven process in the world is dominated by single-layer hot-air cloth, and the material is thicker than the hot-rolled spunbonded non-woven fabric of the same weight, but for the designers of sanitary napkins and diapers, the greater Thickness and elasticity allow for faster liquid penetration and reduced liquid rewetting
The hot-air nonwoven fabric used for the air-flow guide layer is one of the hot-air nonwoven fabrics. Generally, after the hot-air cloth is formed, it will be punched off-line to improve the air permeability of the hot-air cloth. However, its production speed is slow, energy consumption is high, and the process Trouble, making nonwovens production costly

Abstract

The invention relates to the technical field of textiles, in particular to a high-fluffy moisture-absorption breathable fiber net and a perforation and obfuscation method thereof. The high-fluffy moisture-absorption breathable fiber net comprises thermal contraction fibers, dual-component fibers and viscose. The dual-component fibers are of PE-PET-dual-component structures or PE-PP-dual-componentstructures. According to the high-fluffy moisture-absorption breathable fiber net and the perforation and obfuscation method, the dual-component fibers with thermal plasticity and the viscose are blended, and the fiber net is perforated before hot air bonding, so that a non-woven fabric is perforated in the forming process, namely, the non-woven fabric is perforated before a finished product, andthe perforation is conducted by aligning corresponding positions of the fiber net with poor thermal bonding strength; then hot air bonding is conducted on the whole fiber net through hot air bonding of a six-area oven, hole shapes are obfuscated, and perforation and obfuscation of the high-fluffy moisture-absorption breathable fiber net are completed.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a high-loft, moisture-absorbing and air-permeable fiber web and a punching and blurring method thereof. Background technique [0002] High-fluff moisture-absorbing and breathable fiber web is a kind of hot-air nonwoven fabric, which is made by thermal bonding process and perforated fuzzy treatment. After netting, the fiber web is punched by the punching device, and then the fiber is heated by hot air. When the PE component in the bi-component fiber is melted, the fibers overlap each other, and then the fibers around the punched position are thermally bonded, so that The shape of the hole is blurred, and after cooling, it becomes a moisture-absorbing and breathable nonwoven fabric with certain tensile properties. Since it is not subjected to pressure during processing, the bulkiness of air-through nonwovens is far better than that of nonwovens made by other processes. Because o...
