Asahi Asahi Light High Elastic Fabric Is Recognized By The Market.

< p > > Asahi Asahi commercial and Asahi Asahi a target= "_blank" href= "//www.sjfzxm.com/" > textile < /a > developed high elastic knitted fabric using polyurethane fiber ROICA, and introduced lightweight high elastic fabric series in materials such as trousers, shirts, skirts and coats.

In addition, there are also fabrics and denim for fashion jackets.

The company hopes to further enhance the market share of high elastic fabrics on the basis of the original trousers.

< /p >

< p > the new CONZERO introduced this quarter is about half the unit weight of the existing high elastic knitted products, and lightness is the main feature.

The series of fabrics are divided into two kinds of polyester fiber and nylon fiber, all of which have the characteristics of light and thin fabrics, and have the design of pattern printing and dyeing for the making of shirts.

The fabric can be reinforced by bonding, and can also be used for making spring coats.

In the future, the company will further develop products with creativity and design through embossing and wrinkling.

< p > in terms of the high elastic fabric used for fashionable dress, the company will introduce the lace decoration and jacquard pattern < a href= "//www.sjfzxm.com/news/" > the printing and dyeing fabric < /a > for the coat material.

For men's fabrics, it will be applied to coat materials to enhance the elasticity of materials through resin processing.

In addition, Asahi Asahi has also developed a new ROICA SP denim fabric with high chlorine resistance, which is added to KAIHARA, a denim garment manufacturer. This fabric has added value through folds and water washing.

Besides P, the Asahi Asahi has further enriched the high resilient knitted fabric trousers with the strong resilience of ROICA SP and the characteristics that are not easy to slip from the knees, as well as functional products such as cool, comfortable and high elastic trousers with nylon fibers.

Through globalization, we have flexibly applied sewing bases in China, Thailand and Burma, and striving to further expand the market.

< p > News extension < a href= "//www.sjfzxm.com/news/index_c.asp" > polyurethane fiber < /a > knowledge < /p >

< p > alias < /p >.

< p > short for polyurethane fiber, also known as polyurethane elastic fiber. China calls spandex.

< /p >

< p > ingredient structure < /p >

< p > synthetic fibers made of dry polyurethane or dry spinning.

It has a high elastic recovery rate and high elongation at break, similar to that of rubber wire. The elastic elongation is 400% to 700%. When the elongation is 500% to 600%, the elastic recovery rate is 97% to 98%, but the strength is low, only 8.8cN/dtex.

< p > editor's brief history of development < /p >

< p > a brief history of development < /p >

< p > polyurethane fiber was first industrialized by the US DuPont Co in 1959, and internationally called spandex (spandex).

In the early 80s, the world's annual production capacity was about 10kt.

Polyurethane fibers are usually dyed with disperse dyes, acid dyes or complex dyes, and can be spun or blended into bare or core spun yarns. They are used to make elastic knitted fabrics or fabrics, such as underwear, ski suit, sportswear, swimsuit, stockings, belts and medical fabrics, < a href= "//www.sjfzxm.com" > spacesuit < /a >.

< p > characteristics < /p >

< p > polyurethane is a block copolymer of polyester or polyether and aromatic diisocyanate terminated with hydroxyl groups.

It consists of flexible long segments (soft segments) and rigid short segments (rigid segments).

The soft segment is a low molecular weight polyester or polyether segment with no crystallinity. It is easy to deform under stress and the resulting fiber can be stretched and deformed. The rigid segment is a crystalline diaryl isocyanate segment with crystallization and pverse crosslinking. It does not produce deformation under stress, prevents lateral slip and makes the fibers have enough resilience.

The soft segment content of polyurethane fiber segment structure is generally not less than 80% ~ 85%. According to the components of the soft segment, it can be divided into two types: polyester type and polyether type.

DuPont Co produces polyether, while American Synthetic Rubber Co produces polyester.

< p > polyurethane is dissolved in organic solvents such as two methylformamide, two methyl acetamide or two methyl sulfoxide, and a spinning solution is obtained. After spinning by dry spinning or wet spinning, the elastic polyurethane fiber is obtained through aqueous solution containing chain extender containing fatty amine two.
