Description

Cobweb jean fabric with novel style

Technical Field

The invention relates to the technical field of spinning, in particular to denim fabric with a distinctive style.

Background

Denim fabric structures are roughly divided into five types: 3/1 texture, 4/1 satin texture, 2/1 texture, towel bottom texture, 3/1 variation texture, different weave structures and different style characteristics. Generally, 3/1 grains are used for more jeans in conventional continents, 4/1 satins are mainly used for more jeans in women's wear fabric, and the grains are fine and smooth. The 2/1 lines are used for linen-like casual jean fabric, and the towel bottom structure is used for casual jean with a plurality of lines. At present, the jean fabrics are commonly used for children's garments, men's garments and women's garments, but the produced finished products are all discordant and have no novelty, and cannot meet the new demand of consumers.

Disclosure of Invention

The invention aims to solve the problems and the defects and provides the cobweb denim with novel style, which has the advantages of air permeability, wear resistance and durability, and the appearance shape of the cobweb denim is like a cobweb; the weaving is convenient, the stop gear is not easy to appear, and the post-finishing technology is relatively stable.

The technical scheme of the invention is realized as follows: the cobweb jean fabric with novel style is characterized by comprising a system of warp yarns and two weft yarns drafted by different spandex, and a variable tissue formed by interweaving the warp yarns and the weft yarns in a 3/1-variable manner;

the warp yarns are sirospun cotton yarns, the sirospun cotton yarns are positioned on the surface layer in the fabric, the cotton of the sirospun cotton yarns is white cotton, the fiber length of the white cotton is 80% in the range of 25-35mm, the white cotton is used longer than the fine cotton by 23-33mm, and the fiber fineness is 18-25um of the fiber diameter width;

the high-F-number weft yarns with different spandex draft multiples are positioned at the bottom layer of the fabric and are formed by air-wrapping spandex fibers by high-F polyester filament polyester fibers with draft ratios of 3.2 times, 3.5 times and 288F, the high-F polyester fibers enable the fabric to be soft in hand feeling and comfortable to wear, and the spandex is shrunk to 125 percent of warp tightness and 42 to 45 percent of weft tightness after being washed with water at low temperature.

The invention has the beneficial effects that: (1) the fabric has novel style and unique grains, is suitable for the requirement of consumers for new products, is convenient to weave, is not easy to have a stop, and has relatively stable post-finishing technology. (2) The novel denim with different textures is invented by reasonably matching yarns by using the novel texture of 3/1. The hand feeling is between knitting and tatting, the knitted fabric has the softness and the stiffness of tatting, the grains are exquisite and fine, the wearability is wide, and the knitted fabric is suitable for children's clothes, women's clothes and the like. Its advantages are high air permeability, high antiwear nature, and high resilience and plasticity. (3) In order to improve the air permeability, wear resistance and rebound resilience of the fabric, the holding force among fibers is increased by the length, fineness and yarn twist of the fibers, and the wear resistance of the fabric is enhanced. The air-wrapped polyurethane fiber with the fine-denier high-F polyester filament yarn polyester fiber improves the soft hand feeling and the rebound resilience. 3/1 change tissue suitable for dobby loom is selected, and is woven by using a straight-through drafting, the change tissue reasonably staggers tissue points, a cobweb effect is formed, and the air permeability is improved. Through the combination of three aspects of yarn selection, reasonable tissue collocation and production convenience, after the fabric is made into ready-made clothes, the comfortable wearing requirement can be met, and the requirements of enterprises on improving the utilization rate of the fabric, facilitating production and reducing loss can be met.

The technical solution of the present invention will be further explained with reference to the specific embodiments.

Detailed Description

The cobweb denim with novel style comprises a system of warp yarns and two weft yarns drafted by different spandex, and is formed by changing and interweaving 3/1. The warp yarns are sirospun cotton yarns, and are positioned on the surface layer in the fabric, wherein the cotton yarns are white cotton, the fiber length is 80% between 25 and 35mm, the use of the cotton is longer than that of fine cotton wool by 23 to 33mm, and the fiber diameter width in the aspect of the surface fiber fineness is 18 to 25 mu m. The high-F-number weft yarns with different spandex draft multiples are positioned at the bottom layer of the fabric and are formed by air-wrapping spandex fibers by high-F polyester filament polyester fibers with draft ratios of 3.2 times, 3.5 times and 288F, the high-F polyester fibers enable the fabric to be soft in hand feeling and comfortable to wear, the spandex is shrunk to 125 percent of warp tightness after being washed with water at low temperature, and 42 to 45 percent of weft tightness, and the warp and weft tightness can be adjusted to enable the fabric to be stretched by more than 50 percent after being washed. The growth rate of the fabric is 4 percent and the recovery rate is 90 to 93 percent after the fabric is attached with a weight of 1.8KG for 30 min.

The method comprises the steps of preparing the embryo yarn → drawing warp → sizing → coloring → drafting buckle → weaving on a machine. When the fabric is started, the starting parameters of the warp and weft yarns are adjusted, the tension is 4.5-5KN, the opening is 26 cm, the height of the back beam is 10 cm, the depth of the back beam is 3 cm, when the weaving density of the fabric is designed, the tightness on the gray fabric is reduced to 55% of warp and 35% of weft by combining the high contractibility of spandex, the weaving structure is selected, the fabric is woven, and desizing, contraction and finishing are carried out on the woven gray fabric. The desizing and finishing process comprises the following specific steps: singeing the surface on a single row of fire at the front, desizing (desizing at 80 ℃ and passing through 8 desizing grooves), shrinking (4.5-5 KG steam shrinking), and rolling the finished product. And after the gray cloth is contracted, the warp density of a finished product is 117 pieces/inch, the weft density of the finished product is 68 pieces/inch, the width of the finished product is 55-56 inches, and finally the finished fabric product is packaged. In order to keep the characteristics of softness, comfort and large resilience of the cobweb jeans, the cobweb jeans are singed singly, the singeing temperature is controlled well, and the elasticity of spandex is protected, so that the aims of softness and good elastic recovery of the fabric are fulfilled. In the aspect of fabric washing, the washing temperature is controlled to be 50-55 ℃, the washing time is 30 minutes, the drying temperature is 80-85 ℃, the drying time is 30 minutes, the warp density of the washed fabric is 156 pieces/inch, the weft density of the washed fabric is 69 pieces/inch, and the rebound resilience, the softness and the air permeability of the washed fabric can achieve the best effect.

While the preferred embodiments of the present invention have been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention.
