(54) SHEETS FOR THE PRODUCTION OF HEADDRESSES

one

The invention relates to the textile and haberdashery industry and concerns tapes for the manufacture of headdresses (summer women's hats).

Known is the technology of making shl by forming the basics of knitted synthetic knitwear on presses, followed by sewing the edging tape on the sewing machine. In this case, the webbing is used only as a edging material (accessories) and cannot be used to make the headstone itself. These boots are designed for the autumn period, require a sophisticated finish and are not used in the summer.

Also known is the technology of making heads by joining in a crooked crown with external fields, which are sequentially embroidered on a special sewing machine and thus form the heading as a whole. 2. The band for making the heading (cords and fields) is not used. This heading technology is a two-step process, requires new specialized sewing equipment and is designed to produce special headgear (helmets) with rigid fields.

Known braid for the manufacture of hats, having a woven structure 3. The braid is made of frosted monopolypropylene yarns with a diameter of 0.15 mm. The tape width is 5.5 mm, the density of the weave is 5 threads per 1 cm, and the weight is 1 running. m. 1.12g. In order to provide the possibility of better styling of the braid during the manufacture of hats, viscose strand main threads 44.4 tex are missing in its hem. The braid is made on a braider class 21.

However, it is not possible to interchange the main yarns and braid threads in such a braid.

one relative to the other in a wide range, which worsens the conditions for laying the tape when it is sewn into the head. The consequence of this is poor-quality tailoring. In addition, it is difficult to move the prodzhechnoy yarn relative to other strands of the braid due to their considerable surface contact (a consequence of the braided structure), which also worsens the conditions for styling the braid when sewing it into a head. The technology of the weave has small patterned possibilities, which does not allow for augmentation and a diverse pattern on the structure. The hat has a large mass, since the braid is a relatively dense structure, and this requires an increased consumption of raw materials for the manufacture of the band, and consequently, slaves.

The aim of the invention is to improve the quality of the webbing.

This is achieved by the fact that the band for the manufacture of headgear, at least in one edge of which is nponyij: single chain posts.

An advantageous variant is a braid, in which a yarn is stitched in every fourth loop of the outermost column of a single chain, and transverse weft yarns are also inserted in every fourth loop stitch.

FIG. 1 shows a diagram of the structure of the braid for making headwear; in fig. 2 - headdress made of braid.

The band for the manufacture of headwear is made of the bases of single chains 1-4, connected by transverse weft threads 5, arranged zigzag relative to the columns of chains 1-4. Prodzhechna thread vzana in the form of a vertical weft 6 in the loop - one of the extreme columns of the chain (in the loop chain 1). This does not exclude the option in which vertical duck 6 will be inserted not into the most extreme looped column of chain 1, but, for example, into column of chain 2. Vertical duck 6 can be skipped from both edges of the webbing.

Thus, as if strung on transverse weft yarns, the columns of single chains can freely move along the transverse weft yarns, which improves the conditions for styling the braid when sewing. The small surface contact of the weft-shaped prodder thread with the loops of the chains facilitates the displacement of the prodzhechnoy thread relative to the loops of the chain, which also improves the conditions for styling the ribbon when sewing the product. The basics of the string structure allows you to create a wide range of openwork weaves. The net structure of the braid gives a small mass of products as a whole. The use of the basics of hall machines provides high performance with a comparatively (with braiding machines) low noise levels in production workshops.

The vertical thread in the form of a vertical weft 6 can be inserted into every fourth loop of the last column of the chain 1,

and the transverse weft yarns 5 can also be inserted in every fourth looped row (see Fig. 1). The precise location (entry) indicates that these threads are located between the looped sticks and the loop.

Performing braid on the raw material composition.

Example 1. Single chains - kapron complex thread Tex - 93,7. The cross duck is a whiskey straw. Prodzhechna thread - kapron thread.

Example 2. Single chains - kapron complex thread Tex - 93,7. Transverse weft - polypropylene fibrillated yarn Tex - 500. Prodzhechna yarn - kapron yarn.

Example 3. Single chains - kapron monofilament D - 0.15 mm. Transverse weft - viscous straw or polypropylene fibrillated thread Tex - 500. Prodzhechna thread - kapron monofilament D - 0.2 mm.

The technology in the yankeys is not new and is carried out by the well-known method in the yang on a refining machine of a known type.

The process of making the headgear is as follows: the braid is stitched in a spiral on a known sewing machine, and a headdress pattern is formed. When sewing laces, it is assembled on a yarn prodazhechnoy: the degree of fit is adjusted depending on the desired form of headgear.

In order to ensure uniformity of bending of the braid in one plane, the structure of its weaving is constructed so that the inner edge of the braid is less filled, and the outer, scalloped one, when using the dissolving thread, can open.

The technical and economic advantages of the invention are as follows: the duration of tailoring of the headdress is reduced as a result of shortening the length of the seam along the entire length of the headdress, which increases labor productivity; reduced cost due to reduced consumption per unit of product. A hat made of braid has improved hygienic properties due to increased air permeability and a small mass.
