Abstract: PROBLEM TO BE SOLVED: To excellently open a dust collecting bag at use starting time, and to maintain initial performance such as a low pressure loss and high scavanging performance over a long period when using an electret melt blow nonwoven fabric. SOLUTION: A dust collecting bag for a vacuum cleaner is composed of a laminated body 10 of at least three layers by laminating an inner layer 1, an intermediate layer 2 and an outer layer 3 in order in the passing direction of suction air. Then, the inner layer 1 is a nonwoven fabric having rupture strength not less than 0.7 kg/50 mm (6.9 N/50 mm), the intermediate layer 2 is an electret melt blow nonwoven fabric having an average pore diameter of 10 to 30 μm and a maximum pore diameter not more than 45 μm, and the outer layer 3 is a nonwoven fabric having rupture strength not less than 1.5 kg/cm2 (14.7 N/cm2) and 1% elongation time strength not less than 1.5 kg/50 mm (14.7 N/50 mm).

Abstract: PURPOSE: To enable displaying on the entire surface of a floor with a product laid on the floor by a method wherein a base cloth is so arranged to be a fabric with a specified range of opening rate or a fabric impregnated with a transparent resin while a light transmitting resin in used as a backing resin. CONSTITUTION: Piles 1 are tufted onto a base cloth 2 and fixed with a backing resin 3. A light transmitting carpet made up of the piles 1, the base cloth 2 and the backing resin 3 is laminated tightly on the surface of a transparent resin of a light emitting display product comprising a transparent resin sheet 4, a reflection layer 5 and a light source 6. Light from the light source 6 develops a light emitting display over the entire surface of the light transmitting carpet while being reflected on the reflection surface 5. It is important that the base cloth 2 herein used should have 20% or more of light transmissivity, should be so arranged to be a fabric with the opening rate thereof of 5%-80% or a fabric impregnated with a transparent resin. It is also important that the backing resin should be a light transmitting resin.

Abstract: PURPOSE:To obtain a fabric laminate bondable by heat and sufficient in the durability of the resultant adhesive force, thus useful as e.g. a label or escutcheon. CONSTITUTION:One side of a fabric 1 is laminated, via a tack layer 2, with a sheetlike hot-melt adhesive 3 so as to cover the entire surface. Specifically, one side of the fabric 1 or the sheetlike hot-melt adhesive 3 is coated with a tack agent 2 followed by mutually laminating the fabric 1 and the sheetlike hot-melt adhesive. A fabric label printer, equipped with at least a fabric roll and a sheetlike hot-melt adhesive roll, has the following three processes: 1st process: printed images are formed on the fabric by heat-sensitive transfer or ink jet or dot impact method; 2nd process: one side of a fabric 1 or hot-melt adhesive 3 film is coated with a tack agent 2; and 3rd process: the fabric 1 is laminated, via the tack agent 2, with the hot-melt adhesive 3 film.
