Embodiment 1

[0049] Preparation of imitation silk polyester blanket:

[0050] S1: Yarn selection, choose 150D / 288f cross-section polyester full-drawn yarn for blanket fleece, glossy yarn, tenacity 950cN, breaking strength 4.1cN / dtex. The oil content is 1.6%. The bottom yarn is preferably native FDY, specification 75D / 36f. The oil content is 1.6%.

[0051] S2: Blank scarf weaving: the model is E22 warp knitting machine, using Raschel double needle bed warp knitting machine for knitting, and the gauge is 10mm. The base fabric is woven with 3-needle and 4-needle alternate weft insertion and chain knitting, the veil is threaded in a full-closing and closed-end way, and then cut from the middle to obtain a blank scarf. Density is set to warp density 9.8 turns / cm, weft density 8.8 turns / cm, square meter weight 320g / m 2 .

[0052] S3: Pre-treatment of blank scarf: brushing → pre-ironing → brushing → pre-ironing.

[0053] The bristles are brushed with two combing machines with 8 knives. Too...

Embodiment 2

[0063] Embodiment 2 differs from Embodiment 1 in that:

[0064] S1: Yarn selection, choose 75D / 144f cross-section polyester full-drawn yarn for blanket yarn, glossy yarn, tenacity 650cN, breaking strength 3.2cN / dtex. The oil content is 1.5%. The bottom yarn is preferably native FDY, specification 75D / 36f. The oil content is 1.8%.

[0065] S2: Blank scarf weaving: the model is E22 warp knitting machine, using Raschel double needle bed warp knitting machine for knitting, and the gauge is 8mm. The base fabric is woven with 3-needle and 4-needle alternate weft insertion and chain knitting, the veil is threaded in a full-closing and closed-end way, and then cut from the middle to obtain a blank scarf. Density is set to warp density 10.2 turns / cm, weft density 9.8 turns / cm, square meter weight 190g / m 2 .

[0066] S3: Raising the reverse side, use the steel needle of the wire raising machine to evenly pull out a layer of fluff on the back of the blank towel, the cloth speed is 1...

Embodiment 3

[0070] Embodiment 3 differs from Embodiment 1 in that:

[0071] S1: Yarn selection, blanket fleece yarn chooses 120D / 192f cross-section polyester full-drawn yarn, glossy yarn, tenacity 810cN, breaking strength 3.9cN / dtex. The oil content is 1.5%. Bottom yarn is preferably native FDY, specification 100D / 48f. The oil content is 1.5%.

[0072] S2: Blank scarf weaving: the model is E22 warp knitting machine, using Raschel double needle bed warp knitting machine for knitting, and the gauge is 8mm. The base fabric is woven with 4-needle and 5-needle alternate weft insertion and chain knitting, and the veil is threaded in a full-closed way, and then cut from the middle to obtain a blank scarf. Density is set to warp density 8.5 turns / cm, weft density 8 turns / cm, square meter weight 250g / m 2 .

[0073] S3: Raising the reverse side, use the steel needle of the wire raising machine to evenly pull out a layer of fluff on the back of the blank towel, the cloth speed is 11m / min, the c...

Abstract

The invention provides a method for preparing a simulated silk polyester blanket, which includes: yarn selection: polyester full-drawn silk glossy yarn with a cross section is used as the blanket yarn, raw FDY is used as the bottom yarn, and the oil content is 1.5%- 1.8%; Blank scarf weaving: According to the gauge 8mm-12mm, use Raschel double-needle bed warp knitting machine to knit the base fabric with 3-needle and 4-needle alternate weft insertion and knitting chain, and the veil is worn in a full-cloth closed-end method Yarn, cut from the middle after the weaving is completed, and the blank scarf can be obtained; the blank scarf pre-treatment: use two carding machines with 8 knives to brush, and perform brushing treatment. The knife distance of the brushing treatment is 1.2mm, and the speed is 7m / min. At a temperature of 193°C, scalding treatment is carried out at a speed of 16m / min, and then brushing treatment and scalding treatment are repeated; color paste preparation; printing, dyeing and coloring; brushing and scalding treatment; finished product production. Through the technical scheme of the present invention, the fiber shape of the prepared imitation silk polyester blanket is similar to that of the real silk polyester blanket, and has the luster, coolness, skin-friendly and hygroscopic effects of silk.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for preparing a simulated silk polyester blanket. Background technique [0002] Silk is composed of protein fibers and has excellent biocompatibility with the human body. In addition to its smooth surface, its frictional stimulation coefficient to the human body is the smallest among all kinds of fibers, only 7.4%. Therefore, when our delicate skin meets the smooth and delicate silk, with its unique soft texture, it follows the curve of the human body, caring for every inch of our skin thoughtfully and safely. [0003] Silk protein fibers are rich in many amino groups (-CHNH), amino groups (-NH 2 ) and other hydrophilic genes, and because of its porosity, it is easy for water molecules to diffuse, so it can attract or emit water in the air, and maintain a certain amount of water. In summer, it can quickly dissipate the sweat and heat discharged from the human body, ma...
