Nonwoven fabric sheet having cleaning function

Abstract

A nonwoven fabric sheet having cleaning ability which comprises a web layer (i) formed by the airlaying process which consists mainly of heat-bondable fibers having a fineness of 1.5-50 dtex and has a basis weight of 10-250 g / m<2> and, superposed over the layer (i), a web layer (ii) formed by the airlaying process which consists mainly of 20-100 wt.% heat-bondable fibers (a) having a fineness of 1-4.4 dtex and 80-0 wt.% cellulosic pulp (b) [provided that (a)+(b)=100 wt.%] and has a basis weight of 10-400 g / m<2>, and optionally further includes, superposed over the web layer (ii), a web layer (iii) which is the same as the web layer (i), these layers having been united into a sheet as a whole by the thermal bonding of these heat-bondable fibers. The sheet contains an ingredient (c) comprising either a powder (c1) of an alkaline inorganic salt having cleaning ability or an additive (c2) comprising a powdery organic acid having a hydroxy group and a melting point of 70 DEG C or higher, the ingredient (c) being disposed in an amount of 5-300 g / m<2> in at least one of the following positions: at the interface between the layer (i) and the layer (ii), in the layer (ii), and at the interface between the layer (ii) and the layer (iii). The sheet has an overall basis weight of 40-1,500 g / m<2>.

Description

technical field [0001] The present invention relates to a non-woven fabric sheet having a cleaning function, and more specifically, it relates to a non-surfactant inorganic salt or organic acid used as a cleaning agent, so it is safe for humans and the earth's environment, and has sufficient practical properties. Non-woven sheet for washing effect. Background technique [0002] In the past, solid lotion or liquid lotion was mixed with water-containing cleaning sheets ( cloth, sponge, etc.) for cleaning. However, when such a conventional cleaning sheet is used, there is a disadvantage that it must be washed every time, and a cleaning sheet that can be used stably for a long period of time is required. [0003] For example, in Patent Document 1 (Japanese Unexamined Patent Publication No. 11-217354), it is proposed to add and mix a foaming agent to a base material that can be foamed and molded, and to form a sponge-like molded article obtained by foam molding. A surfactant-c...

Problems solved by technology

[0009] Furthermore, these wet products contain about twice as much water as paper and non-woven fabrics, so they are heavy and costly to transport. In addition, the packaging must be sealed and expensive to prevent leakage and dryness.

[0010] Furthermore, this wet cleaning water-dissolving paper is hydrolyzable, so its strength as a non-woven fabric is slightly inferior, and it is often not suitable for use in heavily polluted areas such as stoves.
