Embodiment Construction

[0025] The needle-punched material of the present invention has a thickness of 3.0cm to 3.5cm, and is mainly made of the following raw materials by weight percentage through needle punching process: chopped ultrafine glass fibers with a length of 51mm to 81mm and a single fiber diameter of 3.5μm to 5μm Yarn 95%, 5% high-grade glass fiber chopped strands with a length of 51 mm to 81 mm and a single fiber diameter of 8 μm to 10 μm. Ultra-fine glass fiber and high-grade glass fiber are both alkali-free and wax-free glass fiber.

[0026] The manufacture method of acupuncture material of the present invention, comprises the following steps:

[0027] 1. Selection of raw materials:

[0028] (1) Alkali-free and wax-free ultrafine glass fiber chopped strands with a length of 51 mm to 81 mm and a single fiber diameter of 3.5 μm to 5 μm;

[0029] (2) Alkali-free and wax-free advanced glass fiber chopped strands with a length of 51 mm to 81 mm and a single fiber diameter of 8 μm to 10 μ...

Abstract

The invention belongs to the non-woven weaving industry, in particular relating to a composite multifunctional pinprick material and a manufacturing method thereof. The technical scheme adopted by the invention is as follows: the pinprick materal with the thickness of 3.0-3.5cm is mainly prepared from the following raw materials by weight percent through a pinprick process: 90-95% of superfine glass fiber chopped yarns and 5-10% of high grade glass fiber chopped yarns; and the method for manufacturing the pinprick material has the steps of selecting, opening, mixing, carding, lapping, clamping and pressurizing, feeding and prickling the raw materials. The invention has the following beneficial effects: the pinprick material provided by the invention has the characteristics of radiation resistance, high temperature resistance, corrosion resistance, electric insulation, shock absorption, sound absorption, noise reduction, no toxicity, safety and the like, has small pore diameter, superior sound absorption due to high porosity up to 70-80% and wide application range, and can be widely used in multiple fields.

Description

technical field [0001] The invention belongs to the non-woven and non-woven industry, and in particular relates to a composite multifunctional needle-punched material and a manufacturing method thereof. Background technique [0002] Now the development and application of environmentally friendly materials are getting more and more attention from all over the world. After the 1970s, the production and application of environmentally friendly materials were generally emphasized at home and abroad, and efforts were made to greatly reduce energy consumption, thereby reducing environmental pollution and the greenhouse effect. After nearly 20 years of rapid development in China's environmental protection material industry, many products have grown from scratch, from single to diversified, and from low to high quality, and have formed ceramic fiber, glass wool, calcium silicate insulation products and other varieties. , with the continuous improvement of people's health and environ...
