Embodiment 1

[0040] The elastic fabric material of the present invention comprises a single layer elastic film and two layers of nonwoven fabric. Materials contained in a single layer elastic film, 90% VISTAMAXX TM 1100 Polyolefin Elastomer (ExxonMobil Chemical Product), 5% ELITE TM 5800 linear low density polyethylene (product of Dow Chemical Company), 5% is white masterbatch (Schulman 8500, Shulman). The single-layer film material is manufactured by squeeze casting technology. The basis weight of the film is 20 grams to 14 grams, and the fluctuation point of the extruded basis weight is lower than 20%. These films are extrusion laminated in two layers of 15 g Spunbond-meltblown-meltblown-spunbond (SMMS) elastic polypropylene nonwovens (Golden Phoenix Fiberwebs, Inc.). The resulting elastic cloth material has good stretch and recovery properties, and effectively eliminates holes and tears.

Embodiment 2

[0042] The elastic cloth material of the present invention can comprise the elastic multilayer film of the sandwich structure of two layers of elastic nonwovens and an ABA type, in the sandwich sandwich structure of ABA, there are respectively the multilayer of the ratio of 25%: 50%: 25%. film composition. Among them, on the A floor, 80% are VISTAMAXX TM 1100 Polyolefin Elastomer, 10% ELITE TM 5800 Linear Low Density Polyethylene, 5% INSPIRE TM D118.01 polypropylene homopolymer (Dow Chemical) and 5% for m6060 HDPE (Questa Chemicals). In layer B, 80% are VECTOR TM 421 (Dexco polymer) block copolymer of styrene isoprene styrene (styrene-isoprene-styrene, SIS), 10% ELITE TM 5800 Linear Low Density Polyethylene, 5% INSPIRE TM D118.01 homopolymer polypropylene and 5% white masterbatch (Schulman 8500, Schulman). The multi-layer elastic film is produced by multi-layer extrusion coating technology. The target basis weight of the film is less than 20 grams or even as low ...

Embodiment 3

[0044] The present invention utilizes two 10 g Spunbonded elastic polypropylene nonwovens (GoldenPhoenix Fiberwebs, Inc.) served as both surfaces of the elastomer. The composition of the elastic film contains: 90% VISTAMAXX TM1100 Exxon Mobil, 5% is linear low density polyethylene (LLDPE, ELITE 5800, Dow Chemical), 3% is white masterbatch (Schulman 8500, Shulman), and 2% is processing aid (LUVOFILM 9679 , Lyman Wirth), can be made into a white elastic film. The elastic film is 20 grams, and the final basis weight after composite is 40 grams (10 grams of non-woven fabric + 20 grams of film + 10 grams of non-woven fabric). In comparison, the same elastic sheet has no added LLDPE and is 95% VISTAMAXX TM 1100, 3% is white masterbatch, and under the condition of 2% is processing aid, the elastic film of gained can only reach 46 grams, and total weight is then 66 grams (that is 10 grams of non-woven fabric+46 grams of film+10 grams non-woven fabric).

Abstract

The invention discloses a single-layer elastic film composition, a multi-layer elastic film composition and an elastic sheet. A single-layer elastic film can be formed by at least one elastic polymer with an olefin basis and at least one effective polymer. A multi-layer elastic film can be composed of a first layer and a second layer, wherein the first layer contains at least one elastic polymer with an olefin basis and at least one first slip agent; and the second layer contains at least one elastic polymer and at least one second slip agent. The single-layer elastic film or multi-layer elastic film can be combined with at least one elastic carrier to form one elastic sheet.

Description

technical field [0001] The invention relates to an elastic film and an elastic thin plate which can be used in the fields of clothing, personal hygiene products and the like. Background technique [0002] Elastic fabrics are used in a wide range of applications, for example in garments such as sportswear to provide a snug fit and fit. Elastic fabrics with resilience and effective barrier effects can also be applied to the cuffs of thermal clothing, for example, to prevent the loss of temperature from the cuffs and maintain body temperature. Some types of garments must have suitable resilience and barrier properties at the same time, such as diapers, diapers, etc. for personal hygiene products. The relatively similar elastic cloth technology in the prior art is to use hot melt adhesive to bond non-elastic fabrics (such as ordinary non-woven fabrics) to form a composite material, and then perform physical processing or chemical treatment to make the composite material have E...
