Description

Warp knitting process of elastic fabric
Technical Field
The invention belongs to the technical field of elastic fabric knitting, and particularly relates to a warp knitting process of an elastic fabric.
Background
With the continuous improvement of the living standard of people, the requirements of people on the performance of clothes are continuously improved. The properties of the fabric from which the garment is made will largely determine the quality of the garment. The fabric for making clothes such as underwear and sportswear needs to be made of the fabric with good elasticity in consideration of the factors of comfortable clothes, free movement, beautiful body curve and the like. The existing elastic fabric is mostly prepared by a knitting method, the elastic effect is poor, and especially after long-term use, the original elasticity is lost, so that people are inconvenient to wear.

The invention provides a warp knitting process of an elastic fabric, and aims to solve the problem of poor elastic effect.
The invention is realized in such a way that the warp knitting process of the elastic fabric comprises the following steps:
the method comprises the following steps: selecting wrapping yarns, functional elastic yarns, polyamide fibers, spandex fibers and acrylic fibers as raw materials of the elastic fabric;
step two: carding, drawing, roving, spinning, spooling, doubling, double twisting and yarn steaming, selecting and blending package yarn, functional elastic yarn and spandex fiber to form first yarn, and blending polyamide fiber and acrylic fiber to form second yarn;
step three: knitting to form plain stitch and full plaiting stitch, wherein the first yarn is a face yarn, the second yarn is a ground yarn, the face yarn is always on the front side of the fabric, the length of the first yarn is 15.0cm/70 needles, and the length of the second yarn is 6cm/60 needles to form elastic fabric;
step four: shaping the elastic fabric in the third step to eliminate wrinkles in the elastic fabric;
step five: carrying out rapid dyeing by using Thies and Then aerosol dyeing equipment and adopting aerosol dyeing with an ultra-low bath ratio;
step six: drying the elastic fabric dyed in the step five at the drying temperature of 120 ℃, adding a softening agent after drying, and finally shaping to obtain the elastic fabric;
the functional elastic yarn is polyester elastic fiber.
The fineness of the functional elastic yarn in the step one is 2.5-3dtex, the average length is 60mm, the fineness of the nylon fiber is 2.2-2.7dtex, the average length is 50mm, the fineness of the spandex fiber is 1.5-1.9dtex, the average length is 45mm, the fineness of the acrylic fiber is 1.6-2.dtex, and the average length is 40 mm.
And in the fourth step, a Swiss Santex setting machine is adopted to carry out the setting treatment of single-layer rolling.
Compared with the prior art, the invention has the beneficial effects that: the elastic fabric knitted by the process flow adopted in the first step, the second step, the third step, the fourth step, the fifth step and the sixth step adopts functional elastic yarns with excellent elastic performance, spandex fibers and acrylic fibers as elastic raw materials, so that the elasticity and wearability of the fabric are improved, and meanwhile, the fabric is endowed with good durability and durability, the elastic fabric is free of wrinkles by adopting a single-layer rolling forming machine for forming treatment, the washing size change rate is small, the rapid dyeing is carried out by adopting ultra-low bath ratio aerosol dyeing through Thies and Then aerosol dyeing equipment in the fifth step, certain energy can be saved, the clothes manufactured by the process have soft and comfortable hand feeling, good hygroscopicity and air permeability, and ultrahigh elasticity and recoverability, and are suitable for preparing high-grade knitted underwear and special functional sports clothes, such as knee pads, elbow pads, waist pads, tights, and the like, the manufacturing cost is reduced, and the market application prospect is good.
