A kind of knitting process of elastic knitted double-faced fleece

Abstract

The invention discloses a knitting process of elastic knitted double-faced velvet, including yarn preparation and weft knitting, pretreatment, pretreatment, dyeing, combing, shearing, cleaning and drying, cutting and packaging, including the following steps: step one: yarn preparation and weft knitting: preparing polyester elastic yarn as ground yarn, polylactic acid filament as wool yarn material, and weft knitting the wool yarn polylactic acid filament and the ground yarn polyester elastic yarn to form a grey cloth, step two: pretreatment: washing the grey cloth after preliminary weft knitting, washing the grey cloth by a washing and dehydrating machine, and the washing water temperature is maintained between 55 degrees and 60 degrees. The knitting process of the elastic knitted double-faced velvet further simplifies the original cumbersome process, and the knitted double-faced velvet after knitting is of high quality. Since the grey cloth needs to be cleaned, dried or soaked, etc., workers do not need to work at this time, so that workers can rest while waiting, increase the comfort of workers' work, and avoid negative impact on workers' bodies.

Description

Technical Field

[0001] The invention relates to the technical field of knitted fabrics, in particular to a knitting process for elastic knitted double-faced fleece. Background Art

[0002] The double-faced pile knitted fabric refers to a state in which the surface of the lower needles in the second structure overlaps the surface of the upper needles in the first structure, with respect to the first structure and the second structure constituting the weft knitted structure each having a surface of the upper needles and a surface of the lower needles.

[0003] The existing elastic knitted double-faced fleece has a complicated weaving process and requires a lot of manual operation. It goes through multiple processes and requires repeated manual operations, making it difficult for workers to rest during the operation. Non-stop work will cause physical and mental harm to the workers. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The purpose of the present invention is to provide a weaving process for elastic knitted double-faced fleece, so as to solve the problem in the above-mentioned background technology that the existing elastic knitted double-faced fleece is relatively complicated in the weaving process, requires a lot of manual operation, goes through multiple processes in the weaving process, and requires repeated manual operation, which makes it difficult for humans to rest during the operation, and the non-stop work will cause harm to the workers' physical and mental health.

[0006] (II) Technical solution

[0007] To achieve the above object, the present invention provides the following technical solution: A knitting process for stretch knitted double-faced fleece, including yarn preparation and weft knitting, pretreatment, pretreatment, dyeing, combing, shearing, cleaning and drying, cutting and packaging, including the following steps:

[0008] Step 1: Yarn preparation and weft knitting: Prepare polyester stretch yarn as ground yarn and polylactic acid filament as wool yarn material, and weft knit the wool yarn polylactic acid filament and ground yarn polyester stretch yarn to form a grey cloth;

[0009] Step 2: Pretreatment: Wash the preliminary weft-woven grey cloth, wash it in a washing and drying machine, the washing time is 45 minutes, and the washing water temperature is maintained between 55 degrees and 60 degrees. After washing the weft-woven grey cloth, take it out and dry it, and use a ring drying machine to dry it;

[0010] Step 3: Pretreatment: After the grey cloth is dried, it is subjected to high-temperature treatment at a temperature of 120 to 135 degrees Celsius for 3 minutes. After the treatment is completed, the grey cloth is treated before dyeing with a special cleaning solution. The special cleaning solution materials are soap, scouring enzyme and glutaraldehyde, respectively. The ratio of soap, scouring enzyme and glutaraldehyde is 1:3:1. The prepared cleaning solution is injected into a container and then heated to 60 to 70 degrees Celsius. The grey cloth is fully soaked in the cleaning solution for 30 minutes. After the soaking is completed, the treated grey cloth is taken out to an open space and hung in the air for cleaning. After cleaning, the grey cloth is allowed to air dry naturally;

[0011] Step 4: Dyeing: Place the air-dried fabric in a dyeing vat, and inject the pre-mixed dye into the vat so that the dye can fully contact the fabric. During this period, a longer stick can be used to contact the fabric so that the fabric moves and contacts the dye more fully. The total dyeing time is 45 to 60 minutes. After dyeing, the fabric needs to be evenly cleaned again to clean the residual dye on the fabric, and then the fabric is dried by a ring dryer.

[0012] Step 5: Combing: Lay the fabric flat on a clean surface, use a comb to comb the fluffy side of the fabric repeatedly and evenly to comb out the fluff on the fabric. After combing, turn the fabric over and repeat combing on the other side of the fabric;

[0013] Step 6: Shearing: After combing the fluff on the grey cloth, use scissors to trim the fluff of different heights on both sides of the grey cloth to the same length;

[0014] Step 7: Cleaning and drying: After shearing, soak the fabric in warm water at a temperature between 40 and 45 degrees Celsius to clean and separate the debris and fluff generated during the shearing process. After cleaning, dry the fabric;

[0015] Step 8: Cutting and packaging: Cut the grey cloth to the required size and put the packaging bag on the outside after cutting.

[0016] Preferably, the polyester stretch yarn can also be used as wool yarn.

[0017] Preferably, when the grey cloth is washed, foreign matter is prevented from being contained in the grey cloth.

[0018] Preferably, the ratio of the cleaning liquid to water is 1:4.

[0019] Preferably, in the washing and drying, the water used to wash the fluff debris can be running water, so that the fluff debris can be kept away from the grey cloth.

[0020] Compared with the prior art, the beneficial effects of the present invention are: the original complicated process is further simplified, the quality of the knitted double-sided fleece after weaving is very high, because the grey cloth needs to be cleaned, dried or soaked, etc., and the workers do not need to work at this time, so the workers can rest while waiting, which increases the comfort of the workers' work and avoids negative impact on the workers' bodies.
