Description

A kind of lace fabric with varied shading and preparation method thereof

technical field

The invention belongs to the technical field of clothing fabrics, and in particular relates to a lace fabric with variable shading and a preparation method thereof.

Background technique

With the innovation of textile equipment and the advancement of textile technology, lace fabric, as a fashionable fabric favored by the public, has been more and more widely used since it entered the consumer market, such as underwear, leisure decoration, etc.

In order to achieve a transparent effect, traditional lace fabrics make full use of hole elements in the design. However, these large or small holes, while adding the sexy and aesthetic feeling of the lace fabric, also greatly affect the covering performance of the clothing;

Similarly, although these holes can enhance its breathability and make it more comfortable to wear, it also makes the warmth of lace fabrics not considered by everyone;

In addition, the change of the ground comb structure of the traditional lace fabric changes with the structural change of the weft-inserted ground comb, which is relatively simple and requires some innovative changes;

The easy detachment of traditional lace fabrics is also a potential risk that needs to be faced in application. In view of the risk of detachment, the traditional improvement plan is to increase the weaving density and form a horizontal lock line with a large length change of the looped ground comb, so that the detachment can be stopped at the changing position. However, it greatly affects the appearance of the fabric, and the risk of separation still exists. Another solution to improve the detachment is to use thermal fusible yarns to prevent detachment by taking advantage of their fused properties after high temperature. However, the hot-melt yarn will become hard after being fused at high temperature, which will directly affect the smoothness and good elasticity of the fabric, so it cannot be widely used in production.

After inquiring about the relevant patents and other materials of lace fabrics in the garment industry, there is still no information that can fully describe and effectively solve the above defects and risks, such as:

CN 205062362U describes a warp knitting machine for weaving elastic lace with variable mesh, including a bar cradle and multiple groups of bars. Auxiliary woven ground weave bars are arranged at the required positions, so as to form a mesh effect different from the ground weave process structure, and the woven mesh effect can be guaranteed to be stable.

CN103469469B describes a geometrical element warp knitted lace and a preparation method thereof: two kinds of raw materials, nylon and cation-modified polyester yarn, are woven by lace machine. Lace.

CN107287755B describes a knitting method of a multi-card warp knitting machine: adding a set of positive let-off devices to send out spandex yarns, the spandex yarns are fed into the same or different loop-forming combs as the non-spandex yarns, so that the damaged The back ground yarn loop and the flower yarn are not easy to come off.

In the above-mentioned patents, CN 205062362U is designed based on the permeability of traditional lace and strengthens the stability of the effect of mesh (ie, holes), and CN103469469B increases the diversity of lace fabrics in terms of colors, but they can not improve the traditional lace fabrics in shading. Defects in sex and warmth. CN107287755B Adding a positive let-off device will inevitably increase production cost and maintenance cost. The raw material must be filament and spandex, which also limits the style and type of fabric, and the curing mode of filament and spandex in the same direction will also affect the fabric pattern. form and appearance.

To sum up, the consumer market needs a product that can not only maintain the advantages of traditional lace fabrics such as beautiful patterns, strong three-dimensional sense, various patterns, beautiful and transparent appearance, etc. A new generation of lace fabrics that are releasable at no extra cost.
