Problems solved by technology

Although the all-wood pulp non-woven fabric has the characteristics of green and environmental protection, it has low strength, poor tear resistance, poor wear resistance, and easy to drop slag. The non-woven fabric made of chemical fiber has high strength and good tear resistance. , ideal wear resistance and no slag falling off, etc.

Embodiment 1

[0031] Example 1: Using 10g / ㎡ PP spunbond non-woven fabric as base fabric, using 75% Canadian wood pulp to loosen and grind wood pulp through chain plate machine, pulper, impurity remover, and mill , Made into white water with a solubility of 0.03%, pumped into the wire section of the paper machine through preliminary dehydration to form a wet fiber web into the spunlace machine, spread it flat on the PP cloth, and make the paper dry thickness 30g / ㎡. The pressures of the five spunlace heads in the puncturing process are respectively set to 35bar, 45bar, 65bar, 75bar, and 80bar, and the drying temperature is 115°C.

Embodiment 2

[0032] Example 2: Using 12g / ㎡ PP spunbond non-woven fabric as base fabric, using 75% Canadian wood pulp to loosen and grind the wood pulp through a chain plate machine, a pulper, a de-trash machine, and a mill , Made into white water with a solubility of 0.035%, pumped into the wire section of the paper machine through preliminary dehydration to form a wet fiber web into the spunlace machine, spread it on the PP cloth, and make the paper dry thickness 28g / ㎡. The pressure of the five spunlace heads in the puncturing process is set to 35bar, 45bar, 65bar, 75bar, 80bar, and the drying temperature is 120°C.

Embodiment 3

[0033] Example 3: Using 11g / ㎡ PP spunbond non-woven fabric as base fabric, using 75% Canadian wood pulp to loosen and grind wood pulp through chain plate machine, pulper, impurity remover, and mill , Made into white water with a solubility of 0.03%, pumped into the wire section of the paper machine through preliminary dehydration to form a wet fiber web into the spunlace machine, spread it flat on the PP cloth, and make the dry thickness of the paper 32g / ㎡. The pressure of the five spunlace heads in the puncturing process is set to 35bar, 45bar, 65bar, 75bar, 80bar, and the drying temperature is 120°C.

[0034] After testing, the technical indicators of the composite non-woven fabric prepared by the process of the present invention are shown in the following table:

[0035]

[0036] It can be known from the above test results that the composite non-woven fabric prepared by the process of the present invention has good moisture absorption, high strength, good tear resistance and goo...

Abstract

The invention discloses a production process of PP wood pulp composite wiping cloth, which comprises the following steps: (1) PP non-woven fabrics are unrolled to obtain a base cloth of the bottom layer; (2) a papermaking process, which comprises the following steps: loosening, grinding and removing impurities from the wood pulp to obtain white water, and primarily dehydrating the white water to obtain a wet fiber net; (3) a hydroentangling process, which is to lay the wet fiber net on the base cloth of the bottom layer and perform hydroentangling forming through the hydroentangling process soas to combine the wood pulp fiber with the PP non-woven fabrics; (4) a drying process, namely drying, detecting, coiling and slitting the composite non-woven fabrics formed by the hydroentanglement to obtain the PP wood pulp composite wiping cloth. According to the PP wood pulp composite wiping cloth, the wood pulp fibers and the PP non-woven fabrics are entangled together through a hydroentangling process to form the composite non-woven fabrics, wherein the composite non-woven fabrics has the advantages of being good in molding, soft in hand feeling, double in thickness, environment-friendly, high in strength, good in tear resistance, excellent in wear resistance, not easy to dross, safe and pollution-free, and the production process is simple and the cost is low.

Description

Technical field [0001] The invention relates to the technical field of non-woven fabrics, and more specifically to a production process of a PP wood pulp composite wipe cloth. Background technique [0002] Wiping cloth is a cleaning product made of non-woven fabric. It is widely used in various fields because of its strong absorption, no damage to the surface of the object, and no lint. Although the whole wood pulp non-woven fabric has the characteristics of environmental protection, it has low strength, poor tear resistance, poor wear resistance, and easy slag. Non-woven fabric made of chemical fiber has high strength and good tear resistance. , The advantages of ideal wear resistance and no slag drop. In view of this, the present invention provides a production process of PP wood pulp composite wipes, which combines PP non-woven fabric and wood pulp, so that the product has the high strength, tear resistance and wear resistance of PP non-woven fabric at the same time. Excelle...
