Detailed Description

As shown in fig. 1 and 2, fig. 1 is a front and back sewing diagram of a four-line overlock sewing machine according to the present invention, and fig. 2 is a partial sewing schematic diagram of a waterproof nonwoven fabric sewing structure according to the present invention.

Referring to fig. 1, the waterproof non-woven fabric sewing structure provided by the invention comprises two fabric pieces;

two cloth pieces are spliced together through a four-wire overlock machine at one end, and an outer vertical needle line 1, an inner vertical needle line 2, an upper curved needle line 3 and a lower curved needle line 4 are formed at the spliced position of the two cloth pieces.

When the water absorption test is carried out on the sewing cloth, water absorption paper is paved at the bottom of the sewing cloth, the surface of the sewing cloth is sprayed, the water penetration quantity of the sewing cloth is tested by testing the weight of the water absorption paper before and after spraying, and therefore whether the requirement of the spray test is met is judged.

By carrying out spray test on the sewing cloth structure of the multi-group four-line overlock sewing machine, the water leakage point at the splicing position is found to come from sewing needle threads, so that one or more of the outer standing needle threads 1, the inner standing needle threads 2, the upper bent needle threads 3 and the lower bent needle threads 4 are/is/are waterproof, the water permeation path of the splicing position along the needle threads is effectively blocked, and the sewing cloth structure is further ensured to meet the spray test.

The embodiment also comprises a non-woven fabric waterproof sewing operation garment, which comprises the non-woven fabric waterproof sewing fabric structure.

In this embodiment, the waterproof sewing cloth structure of non-woven fabrics and sewing operation clothes are proposed, two cloth piece one end is in the same place through four-wire overlock car concatenation, forms outer upright needle line, interior upright needle line, go up curved needle line and lower curved needle line in the concatenation department of two cloth pieces, and at least one of outer upright needle line, interior upright needle line, go up curved needle line and lower curved needle line adopts waterproof thread. Through above-mentioned optimal design's waterproof sewing cloth structure, through changing into waterproof line with at least one line of four-wire overlock car, can effectively the separation along the path of permeating water of needle line, reduce the water guide performance of cloth piece concatenation sewing, and then improve the water-proof effects of splice position.

Because the cost of the waterproof wire is higher, four needle wires are replaced by the waterproof wire, and the sewing cost is greatly improved. Therefore, in the specific embodiment, the outer standing needle thread 1 adopts the waterproof thread, and the outer standing needle thread is replaced by the waterproof thread, so that the outer standing needle thread extends along one end of the sewing position, and the outer standing needle thread is replaced by the waterproof thread, so that the penetration path of external liquid along the outer standing needle thread is effectively isolated.

In order to reduce the amount of waterproof thread and thus reduce the cost, further, at least one of the inner vertical needle thread 2, the upper looper thread 3 and the lower looper thread 4 adopts a non-waterproof thread. In a specific sewing process, the inner vertical needle thread 2, the upper looper thread 3 and the lower looper thread 4 can all adopt special threads.

In order to prove the influence of the outer upright needle line changing to the waterproof line on the sewing cloth structure in the spraying test, the embodiment takes 35g of cloth as an example, and the sewing cloth structure when the outer upright needle line adopts a special line and the waterproof line is respectively subjected to the spraying test. Wherein, the inner vertical needle thread, the upper curved needle thread and the lower curved needle thread all adopt extra threads, and only the outer vertical needle thread is replaced.

TABLE 1 spray test results when waterproof threads are used for outer needle and line

According to the spray test standard of the primary operating gown, the water seepage quantity of the position of the splicing seam is required to be less than 4.5g. Referring to table 1, on the premise that the inner needle thread, the upper curved needle thread and the lower curved needle thread are all extra threads, when the outer needle thread adopts extra threads, spray tests show that the sample water seepage amount is about 3-4g, wherein 70% of the sample water seepage amount is lower than 4.5g, the waterproof requirement of the primary operating coat is met, and the sample which does not meet the requirement reaches 30%. However, when the outer needle thread is replaced with the waterproof thread, spray tests show that the sample water seepage amount is about 1-3g, and all the sample water seepage amounts meet the requirements of primary operating gowns.

In addition, referring to fig. 2, in order to further improve the waterproof effect, the outer and inner standing stitches 1 and 2 are tightened at the spliced portion, so that the outer and inner standing stitches 1 and 2 press the cloth, the material is in a tightened state, pinholes are not seen from the front in a smooth state, and the water conductivity of the line is reduced.

Likewise, the upper loopers 3 and the lower loopers 4 are correspondingly tightened.

Further, the inner loopers 2 are pressed against the upper loopers 3 and the lower loopers 4 and grooves 10 are formed at the splice, further pressing the upper loopers 3 and the lower loopers 4.

In this embodiment, compare for four lines all change waterproof line, when guaranteeing the waterproof effect, effectively controlled the sewing cost.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
