Abstract

The invention relates to the technical field of cloth dyeing and finishing, in particular to a printing and dyeing pretreatment process for an imitated silk fabric. Influences to follow-up dyeing dueto poor desizing effect are solved. According to the technical scheme, the printing and dyeing pretreatment process for the imitated silk fabric comprises the steps of rolling, desizing, pre-shaping and reeling. In pre-shaping, a steam spraying device cooperates with a shaping machine, wrinkles on greige cloth are reduced favorably, and then, follow-up dyeing operation is facilitated; the startingtime of an unreeling device, the starting time of a transmission device and the starting time of a reeling device are different, and the effects of desizing and cleaning of the greige cloth are improved favorably, and then follow-up greige cloth dyeing quality is enhanced favorably; and by design of a scraping portion, desizing liquid on the greige cloth in a first cleaning tank and first cleaning liquid on the greige cloth in a second cleaning tank are reduced favorably, and thus, the greige cloth cleaning effect is improved.

Description

Technical field

[0001] The invention relates to the technical field of fabric dyeing and finishing, in particular to a pre-treatment process for imitation silk fabric printing and dyeing. Background technique

[0002] In the textile dyeing and finishing process, the fabric with yarn as the warp must undergo sizing treatment before weaving to improve the strength, wear resistance and smoothness of the warp, thereby reducing warp breakage and ensuring smooth weaving. The pulp used for sizing includes natural pulp such as starch and wild starch, chemical pulp such as polyvinyl alcohol and polyacrylic acid, and cellulose preparation such as carboxymethyl cellulose.

[0003] In actual production, the slurry is unfavorable to the printing and dyeing process, because the existence of the slurry will pollute the dyeing and finishing working fluid, consume dyeing materials, and even hinder the contact between dyeing materials and fibers, and affect the quality of printing and dyeing product...

Examples

Embodiment 1

[0044] Roll the same specification of the grey fabric, reserve a joint before rolling, use a sewing machine to connect the rolled grey fabric to the joint of another roll of grey fabric, and connect multiple rolls of grey fabric in the same way.

[0045] Such as figure 1 As shown, the rolled grey fabric is installed on the unwinding device 1, and the transmission device 2 is used to make the grey fabric pass through the desizing tank 41, the first cleaning tank 42, and the second cleaning tank 43 in sequence. Wherein, the desizing tank 41, the first cleaning tank 42 and the second cleaning tank 43 are all rotatably connected with a cloth pressing rod 5, which is made of polytetrafluoroethylene and arranged horizontally. The desizing tank 41, the first cleaning tank 42, and the second cleaning tank 43 are also provided with overflow ports.

[0046] Reference figure 1 , The desizing tank 41 is provided with a desizing solution, the desizing solution floods the cloth press rod 5 in th...

Embodiment 2

[0054] Roll the same specification of the grey fabric, reserve a joint before rolling, use a sewing machine to connect the rolled grey fabric to the joint of another roll of grey fabric, and connect multiple rolls of grey fabric in the same way.

[0055] Such as figure 2 As shown, the rolled grey fabric is installed on the unwinding device 1, and the transmission device 2 is used to make the grey fabric pass through the desizing tank 41, the first cleaning tank 42, and the second cleaning tank 43 in sequence. The desizing tank 41, the first cleaning tank 42 and the second cleaning tank 43 are all rotatably connected with a cloth pressing rod 5, which is made of polytetrafluoroethylene and arranged horizontally. The desizing tank 41, the first cleaning tank 42, and the second cleaning tank 43 are also provided with overflow ports.

[0056] Reference figure 2 The desizing tank 41 is provided with a desizing liquid, and the desizing liquid floods the cloth pressing rod 5 in the desi...

Embodiment 3

[0066] Except that the unloading rate of the unwinding device 1 is replaced with 4000m / h, the spraying rate of the steam injection device 8 is replaced with 8m / s, and the setting temperature of the gray fabric of the setting machine 9 is replaced with 180°C, the rest of the operations are the same as those in the embodiment. 2 is the same.
