Method of manufacturing folding three face mask with in-depth fabric

Abstract

The present invention relates to a method for manufacturing a folding type three-side mask. The method for manufacturing a folding type three-side mask comprises: a step of coating a hot-melt adhesiveon a lower end of a cotton fabric to form a resin layer; a step of bonding a synthetic nonwoven fabric to the resin layer to form an adhesion assisting synthetic nonwoven fabric layer, and manufacturing a three-layer laminate in which the adhesion assisting synthetic nonwoven fabric, the resin layer, and the cotton fabric are sequentially stacked; a step of putting the laminate on an upper portion of an inner surface of upper filter paper and a lower portion of an inner surface of lower filter paper to make the adhesion assisting synthetic nonwoven fabric of the laminate contact the upper filter paper and the lower filter paper, respectively; and a step of bonding the contact fabric including the cotton fabric and the resin layer to the upper portion of the inner surface of the upper filter paper and the lower portion of the inner surface of the lower filter paper, respectively, by injecting ultrasonic waves to the contact fabric at a temperature of more than or equal to a melting point of a synthetic fabric constituting the adhesion assisting synthetic nonwoven fabric layer.

Description

[0001] related application [0002] This application claims priority from Korean Patent Application No. 10-2017-0122240 filed with the Korean Intellectual Property Office on September 22, 2017, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to the manufacture method of the three-side foldable mask with deep fabric (in-depth fabric), more specifically relates to a kind of method of making the three-side foldable mask with deep fabric which is easy to carry and store with low manufacturing cost through simple process According to the method, the mask can be in close contact with the wearer's facial curvature to improve the filtering performance of fine dust while providing good wearing feeling (touch) and appearance. [0004] As used in this disclosure, the term "three-sided foldable mask with deep fabric" refers to a mask that includes: figure 2 and 3 As shown, (i) the central filter 2 located at the central p...

Problems solved by technology

However, even if irradiated with ultrasonic waves at a high temperature, the cotton fabric contained in the depth fabric 6 burns without melting, so there are lower edge portions and the lower filter 3 where the depth fabric 6 cannot be attached to the inner surface of the upper filter 1 The lower edge portion of the inner surface of the problem

[0008] Meanwhile, when using a depth fabric including synthetic fibers instead of a raw material fabric of cotton fabric as the depth fabric 6, the depth fabric 6 can be attached to the upper edge of the inner surface of the upper filter 1 by fusion bonding using ultrasonic waves. part and the lower edge part of the inner surface of the lower filter 3, but since the raw fabric instead of cotton fabric touches the face of the wearer, the tactility and hygienic effect become poor
