Embodiment approach

[0015] combine figure 1 The manufacturing process of the shown two-color nonwoven fabric of the present invention, the implementation mode of an embodiment of the present invention is as follows:

[0016] Prepare 10,000 grams of polypropylene raw materials, add different color masterbatches to the first and second troughs and mix them, then extrude and spray the raw materials through different screws to form a web, and then pass through the width of 24000-32000mm at a speed of 3m / min 1. The temperature is 110-120 ℃, and the patterned rolls of the rolling mill are rolled and pressed into a cloth, and finally formed. The two-color process is specifically to use two-color masterbatches to add 98% polypropylene to stir, pass through the first and second screws respectively, heat to 210 to 230 ° C to melt into a liquid state, and then enter the screw extrusion, spray The wire is formed into a web, and rolled into a cloth by rolling rolls together. Among them, in specific applicati...

[0019] combine figure 2 The manufacturing process of the shown two-color non-woven fabric of the present invention, another embodiment of the present invention is as follows:

[0020] Prepare 10,000 grams of polypropylene raw materials, add different color masterbatches to the first and second troughs and mix them, then extrude and spray the raw materials through different screws to form a web, and then pass through the width of 24000-32000mm at a speed of 3m / min 1. The temperature is 110-120 ℃, and the patterned rollers of the rolling mill are rolled and rolled into a cloth, and then undergo a hydrophilic process, and finally formed. The hydrophilic process is to add 100 grams of hydrophilic agent to 20,000 grams of high-purity water, then coat (roller), and dry at a high speed to form a cloth. The hydrophilizing agent adopts php37 hydrophilizing agent produced by an American manufacturer, which is used after being diluted with high-purity water. Finally, a hydrophilic two...

Abstract

The invention provides a double-color non-woven fabric and a making process thereof. The making process comprises the following steps of: providing a raw material of a first color and a non-woven fabric raw material, stirring, and extruding the raw materials through a first screw; providing a raw material of a second color and a non-woven fabric raw material, stirring, and extruding the raw materials through a second screw; and jetting with double die heads to form a net, performing layered rolling with an integrated rolling mill, performing hot sticking to form a fabric, performing non-woven fabric formation, and finally obtaining the double-color non-woven fabric. The double-color non-woven fabric can solve the problem of single color of the traditional non-woven fabric, the identification capability and the attractiveness of the non-woven fabric in application are increased, and the non-woven fabric has broad market application prospect.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric and its production, in particular to a two-color nonwoven fabric and its production method. Background technique [0002] Non-woven fabric is a kind of fabric formed without spinning and weaving. It is formed by orienting or randomly arranging short textile fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. become. Compared with traditional textile fabrics, it has the characteristics of short process flow, fast production speed, high output, low cost and wide application. At present, non-woven fabrics are widely used in medical and sanitary fabrics, home decoration fabrics, industrial fabrics, agricultural fabrics, etc. In general, non-woven fabrics are of a single color. In some application fields, such as the medical field or when used for packaging decoration, it is necessary to increase the recognition ability of ...
