Problems solved by technology

Because the washed velvet fabric is made of polyester fiber, the fabric has poor moisture absorption and antistatic effects
When weaving washed velvet fabrics, the friction of the reed on the warp yarns can break the POY monofilaments in the warp yarns and form hairiness, making the opening unclear during weaving

Embodiment 1

[0020] The dyeing and sizing process of a kind of super-imitation cotton and meshed yarn involved in the present embodiment comprises the following steps: step S1 preparation of warp yarn, step S2 warping, step S3 warp beam dyeing pretreatment, step S4 warp beam dyeing, step S5 warp beam soaping, step S6 foam sizing.

[0021] In the preparation of step S1 warp yarn, select 66dtex / 36F polyester super-imitation cotton filament and 16.5dtex, 12F superfine polyester POY to make mixed fiber yarn through network connection, winding, two-for-one twisting, and setting; the prepared The sum of true twist and false twist of mixed fiber yarn is not more than 3800T / m, which is 3500T / m; its false twist is less than 500T / m, which is 400T / m. False twisted yarn has characteristics incomparable to ordinary twisted yarn. It has both true twist and false twist, forming mixed fiber yarn with certain elasticity. The higher the false twist, the stronger the crimp and the greater the resilience, bu...

Embodiment 2

[0032] The dyeing and sizing process of a kind of super-imitation cotton and meshed yarn involved in the present embodiment comprises the following steps: step S1 preparation of warp yarn, step S2 warping, step S3 warp beam dyeing pretreatment, step S4 warp beam dyeing, step S5 warp beam soaping, step S6 foam sizing.

[0033] In the preparation of step S1 warp yarn, the polyester super-imitation cotton filament of 83dtex / 144F and the superfine polyester POY of 28.6dtex and 48F are selected for use, and the blended filaments made by combining, winding, two-for-one twisting, and setting; The sum of true twist and false twist of mixed fiber yarn is not more than 3800T / m, which is 3000T / m, and its false twist is less than 500T / m, which is 450T / m.

[0034] The super-imitation cotton filament and POY are connected to the grid using the Murata No.303 winder to form a grid-connected bobbin; add network nozzles after the gate-type tensioner at each spindle position on the winder and be...

Abstract

The invention discloses a dyeing and sizing process of super-imitation cotton and meshed yarn, which comprises the following steps: step S1 warp yarn preparation, step S2 warping, step S3 warp beam dyeing pretreatment, step S4 warp beam dyeing, step S5 warping Shaft soaping, step S6 foam sizing. The invention relates to a dyeing and sizing process of super-imitation cotton and screen-connected yarn, which adopts super-imitation cotton filament and polyester POY to carry out the mixed fiber yarn prepared by grid-connected two-for-one twisting as warp yarn, and warp beam dyeing is carried out on the warp yarn. Sizing can greatly shorten the weaving process of washed velvet fabrics, shorten the production cycle and improve production efficiency. And optimize the warp beam dyeing process, so that the color difference between the inside and outside of the dyed warp beam meets the requirements.

Description

technical field [0001] The invention relates to the technical field of textile fabric production, in particular to a dyeing and sizing process of super imitation cotton and meshed yarn. Background technique [0002] The raw materials of washed fleece fabrics generally use FDY and POY to prepare mixed fiber yarns through grid-connecting and two-for-one twisting processes. The orientation and crystallization of FDY molecules are higher, so its strength is better than POY. After the alkali reduction treatment, the strength loss of FDY is small, the strength of POY is seriously reduced, and some monofilaments are broken. The polyester FDY and POY are combined and twisted to make the warp yarn and the low-twist low-elasticity yarn. After alkali reduction and water washing, a layer of fine fluff is formed on the surface of the fabric due to the breakage of the POY monofilament. It can form washed fleece fabric. Since the washed velvet fabric is made of polyester fiber, the fabr...
