Problems solved by technology

In order to respond to the reform and innovation of national policies, enterprises need to use less water or no water in the printing and dyeing process. However, the conventional production process of polyester blankets requires 15-18 cubic meters of water to wash 1 ton of printed polyester blankets, and the amount of sewage generated is particularly large.

Embodiment 1

[0031] The invention provides a preparation process of a wash-free regenerated polyester blanket, which mainly includes: raw material selection, weaving, presetting, printing, finishing and finished product production. The specific process is as follows:

[0032] (1) In order to ensure the quality of the yarn, the raw materials are selected as follows:

[0033] Veil: Use recycled polyester DTY with a monofilament fineness of 3.125D,

[0034] Bottom yarn: 150D / 36F recycled polyester FDY,

[0035] By weight percentage: veil 79% and ground yarn 21%.

[0036] (2) Raschel double-needle-bar warp knitting machine is used for weaving. The stripping distance of the double-needle-bar warp knitting machine is 18mm, the wool height is 6mm, the needle size is E18, and the gray fabric weight is 750g / m 2 .

[0037] (3) Pre-finishing process: pre-baking → brushing → pre-scalding → brushing → pre-scalding

[0038] The pre-drying temperature is controlled at 130°C, and the cloth speed is 1...

Embodiment 2

[0049] A recycled polyester blanket produced without washing and its preparation process mainly include: raw material selection, weaving, pre-arrangement, printing, post-arrangement, and finished product production. The specific process is as follows:

[0050] (1) In order to ensure the quality of the yarn, the raw materials are selected as follows:

[0051] Veil: Use recycled polyester DTY with a monofilament fineness of 2.08D,

[0052] Bottom yarn: 100D / 48F recycled polyester FDY,

[0053] By weight percentage: veil 82% and ground yarn 18%.

[0054] (2) Raschel double-needle-bar warp knitting machine is used for weaving. The stripping plate distance of the double-needle-bar warp knitting machine is 20mm, the wool height is 7mm, the needle size is E18, and the gray fabric weight is 850g / m 2 .

[0055] (3) Pre-finishing process: pre-baking → brushing → pre-scalding → brushing → pre-scalding,

[0056] The pre-drying temperature is controlled at 130°C, and the cloth speed is ...

Abstract

The invention discloses a process for producing regenerated polyester woolen blankets. The process includes weaving, pre-drying, pre-brushing, pre-polishing, pre-ironing, flat screen printing, color fixation by ageing integrated machines, stentering drying, brushing, semi-finished product polishing, finished product ironing and shearing and finished product manufacturing. The process has the advantages that the process is implemented by the aid of printing and solidifying integrated machines, accordingly, post-printing washing working procedures can be omitted, and the difficult problem of excessively high water consumption in terylene woolen blanket production procedures can be solved by the aid of the process.

Description

technical field [0001] The present invention relates to the technical field of textiles, and more specifically relates to a preparation process of a washing-free regenerated polyester blanket. Background technique [0002] With the implementation of the new national environmental protection policy, the textile industry, especially the printing and dyeing industry, has particularly strict control over the discharge of pollutants. of printing and dyeing wastewater. In order to respond to the national policy of enterprise reform and innovation, less water or no water is required in the printing and dyeing process, but the conventional production process of polyester blankets requires 15-18 cubic meters of water to wash 1 ton of printed polyester blankets, and the amount of sewage generated is particularly large . [0003] Therefore, how to provide a kind of change production process, the preparation process of the wash-free regenerated polyester blanket that directly carries ...
