Embodiment 1

[0047] (1) Prepare the bottom air-through non-woven fabric, using 100% ES (PE / PET) fibers with a fiber length of 38mm and a fineness of 1.5D, and the obtained bottom air-through non-woven fabric has a grammage of 18g / m 2 . Send the fiber raw materials into the cotton storage box, lay them in piles, grab them vertically and send them to the BG038 opening equipment for loosening and dissociation until they are mixed and opened until they are evenly opened. The resulting opening rate is 95%, and then pass through the BG218 carding machine The bottom fiber web is obtained by carding and cross-lapping machine, and the specific process parameters are: carding machine feeding speed 0.35m / min, cylinder speed 200m / min, web laying speed 46m / min, hot air flat net output speed 20m / min, The hot-air bonding temperature is 156°C, the wind pressure is 50Mpa, and the unevenness of the output fiber web is 2.0%, so as to obtain a hot-air nonwoven fabric.

Abstract

The invention relates to a silk / ES semi-perforated structure non-woven material and a method for preparing the silk / ES semi-perforated structure non-woven material. The non-woven material is formed by compositing two fiber net layers. The two fiber net layers are combined through spunlace in a tangling mode. The surface-layer fibers are provided with holes, the bottom-layer fibers are not provided with holes, and accordingly a semi-perforated structure is formed. The preparing method includes the steps that silk fibers are fed into a cotton storage box, debonding and dissociation are carried out to make the silk fibers evenly mixed and opened, and then carding and net laying are carried out to acquire the surface-layer silk fiber net; opening, carding, net laying and hot air bonding and strengthening are carried out on ES fibers to acquire the bottom-layer fiber net; the surface-layer silk fiber net is laid on the bottom-layer fiber net, the surface-layer silk fiber net and the bottom-layer fiber net are put into a spunlace unit together, and after spunlace forming is finished, dewatering, hydrophilic treatment, drying, winding and cutting are carried out to acquire the silk / ES semi-perforated structure non-woven material. The non-woven material prepared according to the method is provided with the semi-perforated structure, silk utilization ratio is high, water permeation time is short, and reverse osmosis amount is small.

Description

technical field [0001] The invention belongs to the field of nonwoven materials and their preparation, in particular to a silk / ES nonwoven material with a semi-open pore structure and a preparation method thereof. Background technique [0002] Silkworms cannot be exposed to any pesticides or harmful chemicals during the entire growth process. Silk fibers are thin and soft. The ingredient silk peptide contains 18 kinds of amino acids that are beneficial to the human body. It has strong compatibility with human skin and less irritation (stimulation to the skin) Coefficient of only 7.4%, while polyester is 25.5%), known as the "fiber queen", so silk is often regarded as the most "green" environmental protection fiber. In recent years, the pure natural products developed by some companies - silk needle-punched non-woven fabrics and silk spunlace non-woven fabrics are particularly eye-catching. This product has changed the single purpose of silk as clothing, and it can also be wi...
