Multifunctional three-layered composite flame-retardant shell fabric and preparation method therefor

Abstract

The invention discloses a multifunctional three-layered composite flame-retardant shell fabric and a preparation method therefor. The shell fabric sequentially comprises a woven fabric layer, an E-PTFE film layer and a knitted fabric layer, wherein a glue layer is arranged between the woven fabric layer and the E-PTFE film layer and a glue layer is arranged between the E-PTFE film layer and the knitted fabric layer. The multifunctional three-layered composite flame-retardant shell fabric disclosed by the invention is suitable for offshore oil and gas development, and provides effective protection for the working environment of an offshore oil platform. The shell fabric has the characteristics of permanent flame retardance, high strength, wind protection, salt resistantance, water prevention, oil prevention dirtprevention, static electricity prevention, heat preservation, moisture permeability, safety, light weight and the like.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a multifunctional three-layer composite flame-retardant fabric and a preparation method thereof. Background technique [0002] Offshore oil platforms are buildings that mainly provide production and living facilities for drilling, oil production, consolidation, observation, shopping guidance, construction and other activities at sea. On this small offshore platform, operators are often affected by storms, ocean currents, wind, chemical corrosion, and high-cold environments. The natural conditions are harsh and the operating conditions are very complicated. Moreover, offshore oil platforms are far away from land, so transportation is very difficult. There is not enough safety distance between various equipment on the offshore oil platform, and the space for the operator is limited. The platform is always in the wind, waves, and tides. Once an accident occurs, ...

Problems solved by technology

Flame-retardant cotton fabric is processed by post-finishing process, which has good fireproof effect, but as the number of washings increases, the strength and flame-retardant performance of the fabric will gradually decrease, and the fabric is thick, the yarn count is thicker, and it is comfortable to wear Poor resistance, poor dimensional stability, containing formaldehyde, long-term contact will cause skin allergies

Cotton fabrics need to be fumigated with ammonia gas during the flame retardant process, and ammonia gas has a strong pungent smell, and excessive inhalation is harmful to the human body

In addition, the cotton wool in the middle of the flame-retardant cotton clothes is thick and not easy to clean. If it is cleaned, the cotton wool will be unevenly distributed after washing, which cannot meet the needs of the alpine environment.
