Problems solved by technology

However, most of the existing air-filled composite fabrics have only two layers, and can only maintain two states: inflated state or non-inflated state. The method is relatively simple, and the insulation effect is limited.
And if one part is damaged, it will completely leak air and lose all functions
Many inflatable fabrics increase rigidity and lose softness due to full inflation

Embodiment 1

[0028] Embodiment 1 illustrates the structure in conjunction with the accompanying drawings

[0029] see figure 1 , 2 , 3, 4, in the figure, 1 is the first layer of fabric, 2 is the second layer of fabric, 3 is the third layer of fabric, 4 is the fourth layer of fabric, 5 is the outer layer connecting belt, 6 is the inner layer connecting belt, 11 is the fabric, 12 is the coating, 10 is the inner air chamber, 20 is the first outer air chamber, 30 is the second outer air chamber, 41 is the outer air inlet, 51 is the inner air inlet, 52 is the outer air inflation channel, 61 Inflate channels for the inner layer.

[0030] figure 1 is a schematic diagram of the structure of the coated fabric. The fabric 11 is formed of high-density polyester, nylon or other materials. The coating 12 is polyurethane, polyvinyl chloride or polyacrylate, etc., and the fabric 11 is coated on one side by scraping and calendering. Wherein the coating 12 partially penetrates into the fabric 11 .

Embodiment 2

[0035] Embodiment 2 production process

[0036] After coating, the second layer of fabric 2 and the coated third layer of fabric 3 are coated with adhesive according to the required size intervals for bonding to form an inner layer connection belt 6 . A 2-3 cm wide non-adhesive gap is left laterally at an appropriate place in the bonding area (that is, the inner layer connection belt 6 ) to form an inner layer inflation channel 61 , and an inner inflation port 51 is provided at an appropriate position. Put the first layer of fabric 1 after coating and the fourth layer of fabric 4 after coating according to figure 2 As shown, adhesive agent is coated on the unbonded part of the second layer of fabric 2 and the third layer of fabric 3 and parallel to the inner layer connection belt 6 for bonding to form the outer layer connection belt 5 . Leave the outer layer inflation channel 52 at the bonding place of the first layer of fabric 1 and the fourth layer of fabric 4 periphery, o...

Embodiment 3

[0037] Embodiment 3 specifications and performance

[0038] The composite fabric material used in the experiment is plain polyester fabric coated with PU on one side. The warp density is 680 threads / 10cm, the weft density is 386 threads / 10cm, the thickness is 0.25mm, and the surface density is 102.05g / m2. In the experiment, the critical length of the bonding lap is 2cm, and the inflation pressure of the gas is 0.5Mpa. Such as figure 1 The four-layer fabric is coated on one side with PU and bonded using neoprene as an adhesive. The inflation specification is shown in Table 1, and the heat insulation effect is shown in Table 2.

Abstract

The invention discloses a blockette multi-level inflation composite structure fabric, and relates to the technical field of textile materials and textiles. Four layers of fabrics with single surfaces are flatly arranged, and two adjacent layers are connected with each other through parallel connection belts (5 and 6); an inflation chamber is formed between two adjacent connection belts; the upper connection belt and the lower connection belt of the middle two layers of fabrics are parallel to each other and are staggered from each other at an interval; a first outer inflation chamber (20), a second outer inflation chamber (30) and an outer layer inflation channel (52) are communicated and are communicated with an outer inflation port (41); and an inner layer inflation channel (61) is retained in the inner layer connection belt (6), so that the inner inflation chambers (10) are communicated with one another and are also communicated with an inner inflation port (51). By four layers of fabrics for protection, the cold and heat isolation effect is enhanced; a multi-level adjustment function is realized; the thickness, the isolation performance or the floatage of the composite fabric can be changed; the use of the blockette multi-level inflation composite structure fabric cannot be influenced by local damage; and the blockette multi-level inflation composite structure fabric can be used as a tent material, a floatage device, human body protection or rescue auxiliary equipment and the like.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials and textiles, and relates to a multi-layer inflatable fabric with multi-stage inflatable blocks, different insulation properties and flexible structure, which is a heat-insulating and airtight flexible composite fabric. Background technique: [0002] The isolation between the cold environment and the hot environment and the human body is the most basic content to ensure the comfort of the human body in different environments. At present, two methods are mostly used for protection against cold and hot environments. One is to use a rigid structure to form a movable structure. Although the protection effect is good, the controllability is good, and it can accommodate many people, it is cumbersome, poor in mobility, and high in cost. ; The other is to use flexible materials to make the protective outer layer, and flexible protective materials often adopt a multi-layer structure in order to ...
