Definitions

  • the invention relates to a cotton pad for skin care and cleansing and for cosmetic purposes, with two nonwoven fabric layers.
  • a composite nonwoven fabric having a first soft feel surface and a second face away from the first and rough to the first is known.
  • the layer which forms the rough-feeling surface comprises at least partially thermoplastic fibers, preferably from the class of polyolefins.
  • the other layer comprises natural and / or synthetic fibers, which have a lower fiber thickness than those of the other layer and form the soft-feeling surface.
  • the document teaches to connect the layers by water jet needling together. In a subsequent heat treatment, only the free ends of the thermoplastic fibers projecting from the rough-feeling surface layer are melted to enhance the impression of a rough surface.
  • Out EP 0 405 043 A1 For example, there is known a composite nonwoven material for cosmetic use which has two outer layers forming the first and second surfaces and an inner layer disposed therebetween.
  • the layers may be formed of cotton, viscose, synthetic fibers or a mixture thereof.
  • the cohesion of the layers is created by bonding the outer layers to their peripheral edge regions by means of suitable adhesives or by compression.
  • US-A-5,480,699 shows a two-layer composite nonwoven material for cosmetic use with at least two layers. At least the outer layers are compacted to the same or different extent by embossing. As materials cotton, viscose, synthetic fibers or mixtures thereof are indicated. The possibility of producing embossed patterns on the outer layers is also mentioned.
  • FR-A-2052089 shows a two-layer composite nonwoven fabric for cosmetic purposes made of cotton, whose layers are connected by punctiform or linear embossing
  • EP-A-0 441 667 discloses an at least three-layered cotton pad, wherein on both sides of a thin barrier layer per an absorbent nonwoven fabric layer is provided.
  • the present invention has for its object to provide a cotton pad for skin care and cleansing and cosmetic purposes with two nonwoven fabric layers, which can be produced easily and inexpensively and has different trained surfaces, which can preferably be distinguished by tactile perception, wherein the cotton pad is said to be at least equivalent to known materials in terms of a pleasant feel on the skin of a user.
  • the cellulosic fibers of the first layer which are preferably cotton fibers; especially cotton noils, acts to form a first soft-feeling surface of the cotton pad.
  • the second surface facing away from this first surface which is formed by the second nonwoven fabric layer, feels rougher. This rough feel is due to the melt-set thermoplastic fibers of the second layer and the embossing pattern on the surface of the second layer.
  • first layer has been subjected to water jet needling prior to being bonded to the second nonwoven layer in order to increase the integrity of the fibers of that first layer, particularly if there are a few thermoplastic fibers in that first layer ,
  • the thermoplastic fibers present in the first layer are preferably polyester fibers.
  • the thermoplastic fibers of the second layer are at least partially, but especially 100% polyester fibers.
  • PET fibers polyester fibers
  • the use of polyester fibers (PES) as the first thermoplastic fiber in the top layer proves to be particularly advantageous because of its lofty resiliency, as this can easily and effectively prevent it from being deposited on the opposite surface the second layer provided embossing pattern transmits to the first layer or pushed through to the first layer.
  • the melting point of the first thermoplastic fibers provided in the first layer is higher than the melting point of the second thermoplastic fibers, these first thermoplastic fibers themselves are not melted and the surface of the first layer remains soft and gives a soft, perceived as pleasant feeling, due to the cellulosic fibers, which preferably form 90 to 98% by weight of the first layer.
  • the polyester fibers of the first and in particular of the second layer are bicomponent fibers.
  • the polyester bicomponent fibers of the second layer may comprise a low-melting component of polyethylene (PE) and a higher-melting component of polyester (PES).
  • the polyester bicomponent fibers have a polyester core (PES) and a polyethylene (PE) shell.
  • the fiber thickness of the bicomponent fibers is advantageously 1.0 to 6.5 dtex, in particular 1.2 to 4.0 dtex, and preferably 1.5 to 3.0 dtex.
  • the fiber length is advantageously selected from 10 to 80 mm, in particular from 20 to 70 mm and preferably from 40 to 50 mm.
  • the second layer in addition to the thermoplastic fibers and cellulosic fibers in particular from 50 to 95 wt .-%, and preferably comprises from 70 to 95 wt .-%.
  • the proportion of the thermoplastic fibers preferably formed from polyester bicomponent fibers is from 5 to 50% by weight, and preferably from 5 to 30% by weight, of the particular layer considered.
  • the weight per unit area of the first and the second layer is in each case 100 to 150 g / m 2 .
  • the invention also relates to a method for producing a cotton pad according to the invention with the features of claim 20.
  • the first layer is water jet-needled before the layers are arranged one above the other and joined together by heating the layer arrangement.
  • the heating of the layer arrangement can be achieved in any way ansich, advantageously, a hot gas flow is used for this purpose.
  • FIG. 1 1 schematically shows an embodiment of a composite nonwoven material 2 having a first nonwoven fabric layer 4 which forms a first soft-feeling surface 6, and a second nonwoven fabric layer 8 which forms a rough-feeling surface 10 with respect to the first surface 6.
  • the first layer 4 consists of 100% cotton seedlings. It was water jet needled before being placed over and bonded to the second layer 8.
  • the second layer 8 comprises 87% by weight of cotton combing and 13% by weight of polyester bicomponent fibers.
  • the polyester (PES) bicomponent fibers comprise, as a low-melting component, co-polyesters having a melting point of 160 ° C and, as a higher-melting component, polyesters having a melting point of 260 ° C.
  • the length of the fibers is 51 mm.
  • the fiber thickness is 2.5 dtex.
  • the first surface provides a very soft feel and is suitable for applying lotions, creams or the like.
  • the second surface 10, which has an embossed pattern, is suitable for make-up removal.
  • FIG. 12 shows an embodiment of a composite nonwoven material 12 for forming a cotton pad according to the invention, comprising a first layer 14 consisting of 95% by weight of cotton seedlings and 5% of PES bicomponent fibers associated with FIG. 1
  • the second nonwoven fabric layer 16 consists of 85% by weight of cotton fibers and 15% by weight of polyethylene / polyester (PE / PES) bicomponent fibers, with polyethylene (PE) being the low melting component with a melting point of 120 ° C and polyester (PES) as the core of the bicomponent fiber forms the higher melting component with a melting point of 260 ° C.
