Embodiment 1

[0105] A lightly rolled spunbond polypropylene filament batt (20 g / m 2 ) placed in two 20g / m 2 Comb between polyester webs. The polyester fiber has a linear density of 1.7dtex and a length of 38mm. Such an assembly of three laminated layers is used in e.g. figure 1 The equipment shown is subjected to the action of water spray, and the consolidation energy is 0.12kwh / kg. Then, the nonwoven fabric thus obtained was dried in a ventilated oven at a temperature of 120°C at a rate of 20 m / min. The obtained weight per unit area is 60g / m 2 1. A nonwoven fabric having a ratio R of longitudinal tensile breaking strength to transverse direction of less than 2.

Embodiment 2

[0107] Repeat Example 1, with 2 20g / m 2 The polypropylene mesh replaces the two polyester meshes. The polypropylene fiber had a linear density of 1.7 dtex and a length of 40 mm. Such an assembly of three laminated layers is used in e.g. figure 1 The equipment shown is subjected to the action of water spray, and the consolidation energy is 0.12kwh / kg. Then, the nonwoven fabric thus obtained was dried in a ventilated oven at a temperature of 120°C at a speed of 20 m / min. The obtained weight per unit area is 60g / m 2 , R less than 2 non-woven fabrics.

Abstract

Nonwoven which comprises at least one hydroentangled web of thermoplastic discontinuous fibres, hydroentangled with an unstretched batt of independent, inelastic, continuous filaments oriented at random.

Description

field of invention [0001] The present invention relates to nonwoven fabrics, their method of manufacture and their use as cleaning cloths. background of the invention [0002] In order to make such cleaning articles, it is known to consolidate from pressed thermoplastic webs with heated rolls. This rolling brings about point melting of the thermoplastic fibers of the nonwoven, thereby imparting its cohesion and its mechanical strength. The product obtained by this consolidation method has low mechanical strength, low tear strength and high weight per unit volume. These properties may be good for a dry cleaning cloth, but not the best properties. [0003] In order to solve the problems of mechanical strength and tear strength, a fiber web based on thermoplastic fibers is proposed in US patent application No. The components are consolidated by the action of a pressurized water jet. Since the mechanical strength of this product is mainly due to the low weight / m between the ...
