Description
Technical Field
The invention belongs to the technical field of braid treatment, and particularly relates to a braid preparation method adopting improved polyester fibers and a braid.
Background
With the development of economy and the gradual maturity of the garment market, the development of the auxiliary material industry is also gradually intensified, the requirements of consumers on auxiliary materials gradually approach to finished garments, including various aspects of appearance and performance, and the woven belt, as an important auxiliary material in the garment industry, is not only attached to underwear, but also has applications in various fields of garments, such as girdles, waistbands, sport sleeves and the like. Therefore, the appearance and performance of the webbing are gradually diversified. The traditional dacron is mostly weaved with the dyed yarn, because of the dacron temperature of coloring is higher, if direct with the embryo area dyeing, harm belt body spandex elasticity easily, influence belt body aperture. When the velvet ribbon velvet yarn is used as velvet ribbon velvet yarn, the velvet needs to be cut before the velvet ribbon is taken out of the machine, the color of the front surface of the ribbon is the color of the tangent plane of the yarn, the color difference is formed between the front surface of the ribbon velvet and the ribbon body, and the difficulties in coloring and color matching of the yarn are caused.
Therefore, modified polyester fibers are often adopted to replace conventional polyester fibers for weaving so as to reduce the dyeing difficulty. However, although the dyeing temperature of the modified polyester fiber is low, the modified polyester fiber can be directly dyed after being woven by the grey yarn, and the opening degree of the body cannot be influenced, the dyed grey yarn has a retraction phenomenon, so that the down feeling of the body is poor, and the fluff cannot keep the standing effect. When the woven belt is subjected to post-treatment such as embossing, the pattern of the woven belt is not three-dimensional. Therefore, a new process for improving the above problems is urgently needed.
Disclosure of Invention
In order to solve the technical problems, the invention provides a method for preparing a woven belt by adopting improved polyester fibers and the woven belt.
In order to solve the technical problems, the invention adopts the following technical scheme:
a method for preparing a mesh belt by adopting improved polyester fibers comprises a mesh belt main body which is integrally woven, and comprises the following steps:
selecting modified polyester fiber yarns as pile yarns of the main body of the woven belt, and steaming the modified polyester fiber yarns before the modified polyester fiber yarns are loaded on a loom;
the yarn steaming operation comprises the following steps: collecting raw material modified polyester fiber yarns, dropping the raw material modified polyester fiber yarns on a loose tube to enable the modified polyester fiber yarns to have preset bulkiness, steaming the modified polyester fibers through hot steam, enabling the modified polyester fiber yarns to shrink in the process of steaming the yarns, and dropping the modified polyester fiber yarns on a tight tube after the steaming is finished to obtain finished modified polyester fiber yarns;
and knitting the modified fiber yarn subjected to yarn steaming treatment into a fluff layer of the main braid body by a velvet machine, and then carrying out setting dyeing to obtain the main braid body with the fluff which keeps standing and straight.
The yarn steaming temperature is 70-170 ℃, and preferably 120 ℃.
The yarn steaming time is 30min-100min, preferably 60 min.
The main body of the mesh belt is an elastic mesh belt or a non-elastic mesh belt.
And embossing the fluff layer of the braid main body to obtain a three-dimensional pattern.
The braid comprises a braid main body, wherein a fluff layer is arranged on the braid main body and is formed by weaving modified polyester fiber yarns which are subjected to yarn steaming operation on a velvet machine, and sizing dyeing is performed after weaving is finished.
And embossing the fluff layer of the braid main body to form a three-dimensional pattern.
The invention has the beneficial effects that: because the modified polyester fiber is used as the wool yarn, the grey yarn can be directly knitted and dyed, and the color difference between the cross section of the yarn and the belt body when the wool is cut after the common polyester dyed yarn is knitted is avoided. And the yarn is steamed before weaving, the yarn is fully retracted, so that the fluff can still keep upright after the blank belt is dyed, and the patterns can also keep enough stereoscopic impression when the woven belt is subjected to post-treatment processes such as embossing and the like.
