Problems solved by technology

The air-laid air-laid dry-laid paper, which uses low-priced fluff pulp ultra-short fibers as the main raw material, has a relatively low cost, but is relatively poor in terms of strength, hand feeling, and softness; the use of relatively high-priced short fibers is the main material. The spunlace non-manufacturing fabric of the raw material has obvious advantages in terms of strength, weight, softness, etc., but the production cost is much higher than that of the air-laid dry-laid paper

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0048]The air-laid hydroentangled composite entangled product has at least two-layer structure, at least one layer of which is a fluff pulp ultra-short fiber web after pulp debonding, at least one layer is a non-woven short fiber web, and the fluff pulp ultra-short fiber web The fibers of the nonwoven staple fiber web are intertwined and entwined. The weight of the spunlace composite entanglement product is 30-100g / m 2 . Wherein the content of the ultra-short fiber fluff pulp is 10-70%, the length of the ultra-short fiber is 1.0-2.5mm, and the content of the non-woven short fiber is 30-90%.

[0049] Referring to Fig. 1, a kind of method of manufacturing above-mentioned air-laid hydroentangled composite entanglement product comprises the steps:

[0050] 1. The fluff pulp ultra-short fiber web is formed by air-laid dry-laid paper forming equip...

Abstract

The present invention is one kind of airflow netting and hydro entangling product and its production process and apparatus. The product has structure of at least two layers and includes at least one layer of web of super short down fiber and at least one layer of non-woven short fiber web. The production process includes longitudinally superposing super short down fiber web and non-woven short fiber web and hydro entangling to form composite fiber web structure; drying and winding to form the airflow netting and hydro entangling product. The production apparatus include one frame, at least one down slurry web forming device, at least one short fiber web forming device, at least one hydro entangling device, at least one dewatering device, at least one drying device and one finishing and winding device.

Description

technical field [0001] The invention relates to a nonwoven product, a preparation method and equipment, in particular to an air-laid spunlace composite entanglement product, a preparation method and equipment. technical background [0002] Spunlaced nonwoven fabric technology is a unique and novel nonwoven fabric processing technology, which utilizes the impact of high-speed and high-pressure water flow on the fiber web to promote the intertwining and cohesion of fibers to achieve the purpose of strengthening the fiber web. This technology has no environmental pollution, will not damage the fiber, the product has no adhesive, no lint, the product is soft, drape, moisture absorption, good hand feeling and high strength. The characteristics of the spunlace process determine that the spunlace nonwoven material is one of the nonwoven materials with high technical content, good product style and high praise from consumers. It is widely used in medical supplies, wiping sanitary m...
