Description

A woven fabric with a pleated effect

technical field

The utility model relates to the field of woven fabrics, in particular to a woven fabric with a pleated effect.

Background technique

The appearance pattern and shape structure of woven fabrics can generally be formed in three stages: one is in the formation process of the fabric, that is, it is formed after the warp and weft yarns are interwoven and the fabric is off the machine; The fabric is formed after special finishing processes such as printing and embossing; the third is formed after secondary reprocessing such as shirring and folding of the fabric.

The pleated fabrics used to make pleated skirts and other garments are usually made of ordinary flat fabrics through special finishing processes such as high temperature and high pressure pleat shaping, so as to form regular vertical folds. However, there are still some defects in the pleated fabric obtained in this way:

①Wrinkles must be formed after special finishing such as high temperature and high pressure pleat shaping, which requires high process conditions;

②If the strands of the fabric are curved, it is difficult to ensure the straightness of the pressed pleats, and the finished product will be deformed;

③The pleating and shaping process has limitations in the selection of fabric raw materials, such as polyester and other synthetic fiber fabrics have good thermoplasticity, and can form a relatively durable and stable wrinkle effect after high temperature and high pressure pleating; but for natural fibers, regenerated fibers Such fabrics, such as cotton fabrics, are not easy to form stable and persistent wrinkles through hot ironing. The wrinkled products made of these fabrics will gradually degrade and weaken as time goes by or the number of washings increases;

④Wrinkles formed after finishing such as pressing, if the width, density, etc. of the wrinkles need to be changed, it is often necessary to make complex changes to the production process and equipment accordingly, which is costly and time-consuming, and is generally suitable for mass production.

Contents of the invention

As a result, the crease effect of the fabric is more obvious, and at the same time, it is more economical and practical.

In some embodiments, the first weft yarn is made of cotton yarn, the second weft yarn is made of cotton/ammonia core-spun elastic yarn with the same fineness as the first weft yarn, and the warp yarn is made of all-cotton yarn. cotton yarn. The above materials combined with the fabric structure of the method of the utility model can obtain a relatively good pleated appearance effect, good wearing comfort and economical efficiency.

In some embodiments, the longest said reverse continuous weft float and the longest said front continuous weft float each have at least five continuous float weave points.

In some embodiments, the upward convex wrinkle unit adopts the front longitudinal rib weave, and the front longitudinal rib weave forms the reverse continuous weft floating long line; the concave fold unit adopts the reverse longitudinal rib Weave, the back longitudinal rib weave forms the front continuous weft floating long line. A regular pleated effect can thus also be formed.

Compared with the prior art, the utility model has the following advantages: ① The obtained fabric can form regular wrinkles in the first forming process, that is, after it is weaved off the machine, without special equipment and special post-finishing such as high temperature and high pressure crimping and shaping The process can be realized, which greatly simplifies the manufacturing process and shortens the process;

②The woven fabric of this utility model is formed through the cooperation of a specific structure and elastic weft yarns. The convex wrinkle unit is formed by the mountain-shaped twill weave, and the concave wrinkle unit is formed by the weft-shaped twill weave, so that the fold has clear peaks and valleys. Long-lasting, washable and durable good crease effect, ensuring the straightness and durability of creases;

③ There is no limitation on the types of different fabric raw materials, especially suitable for natural fibers and regenerated fiber fabrics such as cotton fabrics, silk fabrics, bamboo fabrics, etc., and can solve the problem that it is difficult to form a stable and long-lasting pleat effect through hot ironing Question, these natural fibers or regenerated fiber fabrics with pleated effect are especially suitable for making skin-friendly clothing, not only the wrinkles are straight and long-lasting, but also have excellent air permeability and comfort;

④ By changing the width of the plain weave unit, wrinkles of different widths can be flexibly obtained, and wrinkles of different widths can also be superimposed in the warp or weft direction to form composite wrinkles with different density changes from top to bottom or left and right. The utility model The wrinkle forms of the woven fabrics are various and the changes are convenient and quick;

⑤ By changing the color of the warp at the convex crease unit, the concave crease unit or/and the plain unit, the unique effect of convex stripes, concave stripes or/and plain plains in different colors can be formed, and the fabric design and color can be satisfied without complicated processing. Colorful changes are required.
