The three-dimensional flower soaking process of the regenerated flannelette comprises the following steps: (1) taking the regenerated flannelette subjected to high-temperature setting as surface cloth, taking warp knitting mesh cloth as base cloth, bonding the surface cloth and the base cloth by using an adhesive through a flower roller, and performing primary drying and setting; (2) greatly curling the fabric subjected to primary drying and shaping, and then placing the fabric in a heat preservation room for secondary drying and shaping; (3) the fabric subjected to secondary drying and shaping is unrolled and then subjected to tertiary drying and shaping on a conduction band type drying machine, and the three-dimensional foam flower is obtained. The terylene warp-knitted screen cloth naturally shrinks at a high temperature, so that the regenerated lint adhered to the surface of the fine-knitted screen cloth forms three-dimensional foam patterns, the preparation process is simple and easy to implement, a foaming agent is not used in the preparation process, and the method has the advantages of being ecological and environmentally friendly.

Description

Technical Field

[0001] The invention relates to the technical field of bubble pattern fabrics, in particular to a three-dimensional bubble pattern fabric of recycled flannel and a three-dimensional bubble pattern process of the recycled flannel. Background Art

[0002] Traditional three-dimensional foam flowers are usually foamed on fabrics by foaming with foam glue to form three-dimensional printing. However, after using the foaming agent, it is generally necessary to go through salt shrinkage, clean water washing and other processes. Therefore, the use of foam glue wastes a lot of water resources, and there are also sediments in the water, and the sewage is not easy to treat. At the same time, the foam flowers produced by the foaming agent are easy to decompose after heating, and the foam flowers are not stable enough. Summary of the invention

[0003] 1. Technical issues to be solved

[0004] In view of the shortcomings of the prior art, the present invention provides a three-dimensional foam flower fabric of recycled flannel and a three-dimensional foam flower process of recycled flannel, which utilizes the shrinkage property of the fabric itself to prepare the foam flower without a foaming agent, is more environmentally friendly, and solves the problems raised in the above background technology.

[0009] (2) After the fabric has been dried and shaped once, it is curled up and placed in a heat preservation room for secondary drying and shaping;

[0010] (3) After the secondary drying and shaping, the fabric is unwound and then dried and shaped for the third time on a belt dryer to obtain a three-dimensional bubble flower.

[0027] Step 3: After the secondary drying and shaping, the fabric is unwound and then placed on a belt dryer for a third drying and shaping at a speed of 14 m / s at 150° C. to obtain a 255×88 cm recycled flannel three-dimensional foam fabric. Figure 1 shown.

[0028] Example 2

[0029] Step 1, high-temperature shaping of 300×100 cm recycled flannel at 195°C, using the high-temperature shaped 220GSM recycled flannel as the surface fabric, using 300×100 cm 40g polyester warp knitted mesh as the bottom, bonding the surface fabric and the bottom fabric with water-based environmentally friendly nano glue through a flower roller, drying and shaping at 165°C at a speed of 11 m / min, curing the water-based environmentally friendly nano glue, and shrinking the polyester warp knitted mesh to 282×95 cm;

[0030] Step 2, the fabric after primary drying and shaping is curled and placed in a heat preservation room, and the motor is driven to rotate the curled fabric evenly, and secondary drying and shaping is performed at 125°C for 24 hours, so that the base fabric is evenly heated and shrunk, and the polyester warp knitted mesh fabric is shrunk to 270×92cm;

[0031] Step 3: After the secondary drying and shaping, the fabric is unwound and then placed on a belt dryer for a third drying and shaping at a speed of 15 m / s and 150° C. to obtain a 260×90 cm three-dimensional foam flower fabric of recycled flannel.

[0032] Example 3

[0033] Step 1, high-temperature shaping of 300×100 cm recycled flannel at 185°C, using the high-temperature shaped 220GSM recycled flannel as the surface fabric, using 300×100 cm 40g polyester warp knitted mesh as the bottom, bonding the surface fabric and the bottom fabric with water-based environmentally friendly nano glue through a flower roller, drying and shaping at 160°C at a speed of 12 m / min, curing the water-based environmentally friendly nano glue, and shrinking the polyester warp knitted mesh to 280×94 cm;

[0034] Step 2, the fabric after primary drying and shaping is curled and placed in a heat preservation room, and the motor is driven to rotate the curled fabric evenly, and secondary drying and shaping is performed at 115°C for 24 hours, so that the base fabric is evenly heated and shrunk, and the polyester warp knitted mesh fabric is shrunk to 265×92cm;

[0035] Step 3: After the secondary drying and shaping, the fabric is unwound and then placed on a belt dryer for a third drying and shaping at 160° C. at a speed of 14 m / s to obtain a 260×88 cm three-dimensional foam fabric of recycled flannel.

[0036] Comparative Example 1

[0037] Step 1: Use 300×100cm 220GSM recycled flannel as the surface fabric, and 300×100cm 40g polyester warp knitted mesh as the bottom fabric, use a flower roller to glue the surface fabric and the bottom fabric with water-based environmentally friendly nano glue, and dry and shape them at 160°C at a speed of 10 m / min to solidify the water-based environmentally friendly nano glue, shrink the polyester warp knitted mesh to 280×94cm, and shrink the recycled flannel to 190×95cm;

[0038] Step 2: After the fabric is dried and shaped once, it is curled and placed in a heat preservation room. At the same time, the motor is driven to make the curled fabric rotate evenly. It is dried and shaped for a second time at 120°C for 24 hours to make the base fabric shrink evenly due to heat. The polyester warp knitted mesh fabric shrinks to 260×90cm, and the recycled flannel fabric shrinks to 188×94cm.

[0039] Step 3, after the secondary drying and shaping, the fabric is unwound and then placed on a belt dryer for a third drying and shaping at a speed of 14 m / s and at 150°C. The polyester warp knitted mesh shrinks to 255×88 cm, and the recycled flannel shrinks to 185×85 cm. Since the recycled flannel is not subjected to high-temperature shaping, it also shrinks during the subsequent drying and shaping process, resulting in the formed bubble flower not being three-dimensional and failing to meet the bubble flower requirements.
