Problems solved by technology

[0002] With the increasing importance of noise control, the market for non-woven sound insulation materials is generally growing. Manufacturers are paying more and more attention to lightweight materials with excellent performance and affordable prices. Competitive features, most of them are used for car interiors, and some industrial areas. With people's emphasis on life privacy and the development of home entertainment facilities, the application of sound insulation materials in homes will definitely have a big improvement. However, such finished products on the market are not abundant, and the effect is not obvious.

preparation example Construction

[0008] The preparation method of the present invention is the following steps:

[0009] ①. The length of the glass fiber staple is between 35mm-68mm and mechanically carded to output the glass fiber net, the thickness of the fiber net is 0.4-0.7cm;

[0010] ②. Feed another carding machine into the hollow kapok fiber with a length of 32-65mm, and the thickness of the output fiber web is 0.6-1.2cm;

[0011] ③. Feed bamboo fiber with a length of 32-65mm in the third carding machine (or continue to use glass fiber to feed), and the thickness of the output fiber web is also 0.4-0.7cm;

[0012] ④ Lay the obtained fiber nets in parallel in series in sequence. After the nets are laid, they are sent to the needle punching reinforcement through the mesh guide mechanism. , needle density 3000-3560 pieces / m, acupuncture frequency 800-1500rpm;

Embodiment 1

[0015] Ingredients: glass fiber, hollow kapok fiber, bamboo fiber;

[0016] Various methods:

[0017] ①. The length of the glass fiber staple is between 35mm-68mm and mechanically carded to output the glass fiber net, the thickness of the fiber net is 0.4-0.7cm;

[0018] ②. Feed another carding machine into the hollow kapok fiber with a length of 32-65mm, and the thickness of the output fiber web is 0.6-1.2cm;

[0019] ③. Feed bamboo fiber with a length of 32-65mm in the third carding machine (or continue to use glass fiber to feed), and the thickness of the output fiber web is also 0.4-0.7cm;

[0020] ④ Lay the obtained fiber nets in parallel in series in sequence. After the nets are laid, they are sent to the needle punching reinforcement through the mesh guide mechanism. , needle density 3000-3560 pieces / m, acupuncture frequency 800-1500rpm;

Embodiment 2

[0022] Ingredients: glass fiber, hollow kapok fiber, its implementation method is the same as embodiment one, the difference is that what is fed in the third carding machine is glass fiber, which is the same as the first one.

[0023] In summary, the sound-insulating nonwoven fabric of the present invention uses glass fiber, hollow kapok fiber, and bamboo fiber as raw materials, has light weight, excellent performance, simple processing technology, high weaving efficiency, and improves the production value of the product.

Abstract

The invention provides a brand new weaving concept and method of sound insulation non-woven cloth, which adopts non-woven production technique and outputs fiber glass net after mechanic carding on the short fiber with length between 35mm and 68mm of the fiber glass. The invention has simple process and high weaving efficiency, improves the production value of the product, and uses the fiber glass, the hollow ceiba fiber and bamboo fiber as materials, and has light ration, excellent property and good economy and social benefit.

Description

technical field [0001] The invention relates to a method for weaving nonwoven fabrics, in particular to a method for weaving nonwoven fabrics with sound insulation function. Background technique [0002] With the increasing importance of noise control, the market for non-woven sound insulation materials is generally growing. Manufacturers are paying more and more attention to lightweight materials with excellent performance and affordable prices. Competitive features, most of them are used for car interiors, and some industrial areas. With people's emphasis on life privacy and the development of home entertainment facilities, the application of sound insulation materials in homes will definitely have a big improvement. However, such finished products on the market are not abundant and the effect is not obvious. Contents of the invention [0003] The purpose of the present invention is to provide a method for weaving a sound-insulating non-woven fabric with low price and o...
