Detailed Description

The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

As shown in fig. 1-3, the forming process of the ice rescue suit comprises a forming process of a three-layer structure of an outer-layer immersion-resistant suit, a warm-keeping buoyancy inner container and an inner-layer cold protective suit, wherein the warm-keeping buoyancy inner container is detachably fixed on the inner side of the outer-layer immersion-resistant suit, and the inner-layer cold protective suit is independently arranged.

The molding process specifically comprises the following steps:

1. outer-layer anti-soaking garment forming process

The outer layer of the anti-immersion suit comprises a protective hat, a large body and gloves, wherein the large body comprises a coat, trousers, protective boots and fixing pieces.

(1) Helmet part process

The protective cap and the large body of the outer-layer anti-immersion suit are connected into an integrated structure, and the protective cap and the large body of the outer-layer anti-immersion suit have the main functions of wind prevention, water prevention and warm keeping. The protective cap cannot be integrally formed, cut pieces in different shapes are required to be spliced to form a forming structure which is more suitable for the head of a human body, the forming process of the part does not adopt a conventional flat seam or a simple sewing process of four needles, six threads and the like, but adopts a blind seam gluing forming process, so that the protective cap does not have pinholes to penetrate through the inner side and the outer side of the protective cap, and has better windproof, waterproof and warm keeping properties.

The blind seam gluing process includes splicing and adhering the protective cap cutting pieces through an adhesive, and then sewing and reinforcing the protective cap cutting pieces through a blind seam machine. The blind seam refers to a sewing process that sewing threads penetrate from one side of the fabric but do not penetrate to the other side of the fabric to realize splicing and fixing. In this embodiment, the cut-parts of helmet select for use the material of 4mm thickness, all coats the adhesive with the cut-parts both sides that the helmet is waited to connect under normal atmospheric temperature environment, extrudees the concatenation face and makes it adhere completely, places the solidification for 5min at normal atmospheric temperature, carries out the blind seam of adopting single needle double-line chain stitch after the solidification.

In other embodiments, the protective cap may also be formed by sewing a heat-sealing strip. The process for sewing the heat-seal adhesive strips is that protective cap cut pieces are fixed by sewing, the sewing mode includes but is not limited to flat seam, four-needle six-line or blind seam, then adhesive strips are hot-melt adhered to the positions of the sewing stitches through a heat sealing machine, secondary reinforcement is realized, and melted adhesive penetrates and blocks gaps which are penetrated or not completely sewn through the sewing machine, so that the same barrier property and heat retention property are realized.

The main two molding processes adopted by the large body are high-frequency heat sealing and sewing of heat sealing strips so as to form a relatively sealed cavity body for the garment.

The process for sewing the heat-seal adhesive tape is the same as that of the protective cap, wherein the sewing is mainly flat seam. The protective cap and the protective boot adopt the process, the problems of bonding tightness and firmness caused by different material properties of the main body material can be effectively solved by matching the corresponding adhesive tapes, the connecting strength of the connecting piece is increased, and the service life is prolonged.

The principle of the high-frequency heat-sealing process is that a high-frequency electric field of a high-frequency heat-sealing machine is utilized to enable molecules in a material to be bonded to vibrate, so that heat energy is generated to bond the material to be bonded, the shape and the size of a bonding part depend on the shape and the size of a die which is arranged on the high-frequency heat-sealing machine and is in contact with the material to be bonded, and therefore different bonding effects can be achieved by changing the die. The forming characteristic of the process is that new pinholes and other leakage points penetrating through the two sides of the fabric cannot be generated in the splicing, fixing and bonding process, so that the process is more suitable for preparing airtight and watertight products. The zipper, the local reinforcing part and the pocket fixing structure of the large body part of the ice rescue suit adopt the process, and the high-frequency heat seal of the zipper just avoids the problems that the surface of the zipper is smooth, the texture is relatively stiff and not easy to sew; the fixing structures such as the local reinforcing parts, the pocket connecting parts and the like are fixed on the outer surface of the ice rescue suit, and open channels or spaces are reserved for inserting rescue belts, adjusting belts and storing articles such as ice cones and rescue tools, so that the problem of water permeation caused by the fact that each stitch cannot be fully blocked by the open structure in the sewing and heat-sealing strip pasting process can be effectively solved.

The splicing of the cut pieces can adopt a sewing heat-sealing strip pasting process and a high-frequency heat-sealing process. Aiming at diversified products and customized ice rescue clothes, the process of sewing the heat-sealing strip does not need to customize a tooling die, so that the flexibility is better, the production cost can be effectively reduced, and the production efficiency is improved. Aiming at the batched conventional ice rescue suit, the high-frequency heat seal process has a relatively fixed tooling die, and one processing procedure is reduced compared with sewing and strip attaching, so that the production efficiency can be effectively improved, and the processing working hour and cost can be reduced.

In this embodiment, cut out main part surface fabric according to the version type earlier, then carry out the concatenation between cut-parts on one side, on one side fixed zip fastener, local reinforcement, pocket connecting piece isotructure in cut-parts relevant position. Splicing the cut pieces by adopting a flat sewing process, wherein the needle pitch is 10-12 needles/3 cm; and then, sealing by adopting a heat-sealing strip technology, wherein the heat-sealing strip technology parameters are as follows: the polyurethane adhesive tape has the bonding temperature of 300 ℃, the bonding speed of 2.5-3m/min, the bonding wheel pressure of 0.2MPa and the air flow of the air nozzle of 0.5-0.6. The zipper, the local reinforcing component and the pocket connecting piece adopt a high-frequency heat seal process, and the process parameters of the high-frequency heat seal are as follows: the temperature of the zipper is 70 ℃, the current is 0.2A, and the time is 8s; the temperature of the rest parts is 45 ℃, the current is 0.2A, and the time is 5s. And finally, adopting a sewing strip attaching process to connect the protective cap and the protective boot at the positions of the neckline and the foot opening, wherein the sewing process is the same as the sewing process, and the technological parameters of the heat-sealing strip attaching process are as follows: the adhesive tape of polyurethane, the bonding temperature is 450 ℃, the bonding speed is 2.5-3m/min, the bonding wheel pressure is 0.2MPa, and the air quantity of the air nozzle is 0.5-0.6.
