preparation example Construction

[0040] see figure 1 - Figure 9 , a kind of preparation method of elastic nonwoven fabric, described preparation method comprises following process:

[0041] Fiber web stitching process: First, a plurality of elastic ribs 2 are arranged in parallel and equally spaced on the reverse side of the fiber web 1. The front side of 1 introduces a plurality of composite filaments 3 in parallel, the introduction direction of the composite filaments 3 is along the length direction of the fiber web 1, and the stitching method after the introduction of the composite filaments 3 is repeated penetration and exit of the fiber web 1 to consolidate the two ends of each elastic tendon 2 on the opposite surface of the fiber net 1 to obtain a consolidated net body; There is a consolidation point 31 at both ends of the tendon 2; during the overall process of each composite filament 3 penetrating and passing through the fiber web 1, the composite filament 3 swings back and forth along the length d...

Embodiment 1

[0063] see figure 1 - Figure 9 , a method for preparing an elastic nonwoven fabric, comprising the following processes:

[0064] Fiber web stitching process: First, a plurality of elastic ribs 2 are arranged in parallel and equally spaced on the reverse side of the fiber web 1. The front side of 1 introduces a plurality of composite filaments 3 in parallel, the introduction direction of the composite filaments 3 is along the length direction of the fiber web 1, and the stitching method after the introduction of the composite filaments 3 is repeated penetration and exit of the fiber web 1 to consolidate the two ends of each elastic tendon 2 on the opposite surface of the fiber net 1 to obtain a consolidated net body; There is a consolidation point 31 at both ends of the tendon 2; during the overall process of each composite filament 3 penetrating and passing through the fiber web 1, the composite filament 3 swings back and forth along the length direction of the fiber web 1 ...

Embodiment 2

[0068] Basic content is the same as embodiment 1, the difference is:

[0069] see Figure 8 , on the opposite side of the fiber web 1, along the length or width direction of the fiber web 1, a plurality of additional elastic threads 12 are arranged in parallel and at equal intervals. The opposite side of the fiber web 1, and perpendicular to the direction of the elastic tendon 2, repeatedly penetrates and passes through the fiber web 1 at the composite filament 3 so that both ends of each elastic tendon 2 are consolidated on the fiber web 1 On the reverse side, another composite filament 3 is repeatedly inserted into and out of the fiber web 1 so that each additional elastic filament 12 is consolidated on the reverse side of the fiber web 1, and each composite filament 3 and its corresponding additional The elastic wires 12 need to be handed over multiple times, and each handover point is called an additional contact point 13 , and there are multiple additional contact points...

Abstract

The invention provides a preparation method of an elastic non-woven fabric. The preparation method comprises the steps that a plurality of elastic bands are arranged on the reverse side of a fiber webin the length or width direction in parallel at equal intervals, a plurality of composite filaments are introduced into the front side of the fiber web in the length direction of the fiber web, the composite filaments penetrate into and out of the fiber web repeatedly, so that the two ends of each elastic band are fixedly knitted to the reverse side of the fiber web, and a fixed knitting body isobtained; the composite filaments swing back and forth to move forwards in the length direction of the fiber web, wherein the swing direction is the width direction of the fiber web; the fixed knitting net body is placed in a hot environment for heat treatment, so that the fiber web with wrinkles is formed, and the elastic non-woven fabric is obtained. Due to the design, the elasticity is high, the elasticity can be transversely and longitudinally adjusted, the elasticity adjusting independence is high, the cost is low, and the application range is wide.

Description

technical field [0001] The invention relates to an elastic nonwoven fabric, which belongs to the technical field of textiles, in particular to a preparation method of an elastic nonwoven fabric and the elastic nonwoven fabric, which are particularly suitable for enhancing elasticity and can adjust elasticity in both horizontal and vertical directions. Background technique [0002] Non-woven fabrics are made by orienting or randomly arranging textile fibers to form a fiber net structure, and then strengthening them by mechanical, thermal bonding or chemical methods, and have the characteristics of multidisciplinary technology. In recent years, the application field of non-woven fabrics has been continuously expanding, and it has developed very rapidly in the textile field. It is considered to be a new economic growth point for the future development of the textile industry. It can be widely used in clothing, home textiles, medical and health materials, etc. It has attracted t...
