Detailed Description
The following detailed description of specific embodiments of the invention is provided to facilitate further understanding of the invention by those skilled in the art and is not to be construed as limiting the scope of the invention.
Example 1, a method of making a weft-knitted polyester pile blanket:
raw materials, weaving
The raw materials used by the product are divided into the surface silk and the bottom silk. Adopts bright polyester Drawn Textured Yarn (DTY). The adopted fineness/composite number is 300D/576F, and the bottom yarn adopts 150D/36F polyester Fully Drawn Yarn (FDY) or semi-gloss polyester low stretch yarn (DTY).
The method is characterized in that a loop cutting loop velvet machine is adopted for weaving, a wool surface is composed of a creel weaving mechanism, a yarn feeding mechanism, a drawing and winding mechanism and the like, an upper needle cylinder and a lower needle cylinder are respectively a crochet needle and a knife needle, the wool height is adjusted by the distance between the openings of the upper needle cylinder and the lower needle cylinder, the wool height can be woven between 5mm and 18mm, a weaving method with the knitting gauge of 3+3 is selected, namely only one face yarn is woven between every three gauge bottom yarns, the middle two loops are not woven with the face yarns, so that the use of the face yarns can be effectively reduced, the gram weight of a carpet is reduced as far as possible, the full wool length is that the wool height is woven on 45mm (18 mm in the embodiment), the hand feeling of the carpet surface can be soft, and the bottom yarns which are not woven at the bottom can be blocked in the loops, and the bottom exposure phenomenon is avoided.
Secondly, pre-setting of front-finishing high-speed bristles and grey cloth
A24-roller high-speed brushing machine is adopted for brushing high-speed bristles, and fibers are directly opened to avoid the phenomenon that the bristles are not straight and cannot be opened after shaping and then twisting. The parameters of the selected bristles are 70 r/min of the large cylinder rotating speed, 1.18 of front traction force, 1.15 of rear traction force, 15m/min of cloth speed, 22 of left brushing force and 22 of right brushing force.
The presetting adopts a natural gas direct-fired 10-section setting machine, the upper air blow is started for hot air heating, and due to the fact that brushing is firstly carried out and then heat setting is carried out, overfeeding operation is added on overfeeding, and therefore the required width can be maintained.
And (3) bulking and loosening the polyester yarns at high temperature through high-temperature setting, and simultaneously performing tentering setting according to the required width to prepare for subsequent printing or pad dyeing. According to different required style requirements of the felt top, the setting temperature is set to be 170 ℃, and the cloth speed is set to be 30M/MIN.
Third, printing (or pad dyeing), drying and fixing color
The woolen blanket is generally printed or pad-dyed in a printing workshop, wherein the pattern of the printing is made by using 80-mesh screen silk, several sets of pattern plates are generally required to be made for several colors, color paste is printed on the grey cloth at the position where the pattern is required to be dyed, the pattern to be expressed is formed after the colors are combined, the blanket with one color adopts pad-dyeing, namely, the color paste is placed in a water tank, then the grey cloth passes through the color paste and is extruded by a roller, and the redundant color paste is extruded out by the color paste which is generally formed by mixing a thickening agent with certain viscosity and dye according to a certain ratio and adding a certain proportion of water for high-speed stirring. The method comprises the steps of immediately feeding printed or pad-dyed wet cloth into a high-temperature drying and fixing all-in-one machine for drying and fixing color, wherein nine layers of the gas direct-fired drying and fixing all-in-one machine are adopted, the upper three layers are all dried, the temperature is generally 165 ℃, the drying is about 75 percent, the wet cloth enters a color fixing area of the lower six layers for high-temperature color fixing, and the speed is generally controlled at 12m/min in order to ensure that the color fixing temperature reaches 190 ℃.
Fourthly, washing, shaping and drying
The main purposes of water washing are as follows: (1) removing printing paste
(2) Washing dyeing material floating color and oil content in raw material
(3) Improve hand feeling and eliminate static
The process comprises the following steps: cloth speed: 15m/min
A first groove: (anti-staining treatment) temperature 45 ℃;
a second groove: (washing treatment) temperature 35 ℃;
a third groove: (washing treatment) temperature 35 ℃; (ii) a
A fourth groove: (anti-staining treatment) temperature 45 ℃;
fifth groove, sixth groove: washing with water at normal temperature for 25 ℃;
a seventh groove: (antistatic and softening treatment) temperature is 55 ℃;
a hexagonal belt brush beater roller is added into a second groove and a third groove to clean bristles of the gray fabric while washing, so that the carpet is cleaner to clean, and the hand feeling is softer.
After washing, dewatering treatment is carried out, the existing residues on the blanket are thrown away with water when the water is dewatered, drying and shaping are carried out after dewatering, and when the grey cloth is dried, the grey cloth is pulled out according to requirements, the temperature of the width is generally 165 ℃, and the speed is 20 m/min.
Fifthly, after finishing
After high-temperature pressing in each process of printing, washing, shaping and the like, the fiber needs to be brushed again after being shrunk and curled, a 24-roller high-speed brushing machine is continuously adopted for brushing, and various parameters such as brushing force need to be increased, so that the rotating speed of a large cylinder is 80 revolutions per minute, the front tension is 1.25, the rear tension is 1.30, the cloth speed is 15m/min, the left brushing force is 28, and the right brushing force is 28.
Six, high temperature and high pressure rolling bundle
The woolen blanket is thin due to the fact that fibers are straightened after brushing, and due to the fact that the bottom of the woolen blanket is woven by 3+3 tissues, a lot of empty places can exist, and plush cannot be covered, so that the plush on the front side needs to be humidified, pressurized and heated, then rolled and bundled, the plush on the surface is rolled into small particles, the woolen blanket is thick and solid, meanwhile, the woolen blanket is breathable, and the required woolen surface style can be achieved by adding high-temperature and high-pressure steam into the plush on the surface of the woolen blanket and then rolled and bundled.
The technical parameters are as follows: heating and humidifying for 12 minutes, wherein the temperature reaches 115 ℃, and rolling for 12 minutes, the time of the process is determined according to the size requirement of the rough surface particles, the rotating speed is uniform, otherwise, the rough surface particles are uneven or have poor granulation. The cooling time is 8 minutes, after cooling, the cloth is taken out of the roller of the granulator in time, and the cloth is scattered from time to time so as not to form wrinkles.
Seven, later setting
In the respective processes of brushing, pilling and the like, the fabric is subjected to mechanical action or stretching, and thus the fabric is subjected to straight elongation, transverse shrinkage, uneven width and weft arc and weft skew phenomena in the weft direction, so that post-sizing is required, and the width and the gram weight are controlled according to the gram weight of the fabric. The temperature is generally 165 ℃ and the speed 25 m/min.
Eighthly, cutting cloth, wrapping, inspecting, packaging and warehousing
After 3 times of shaping, the blanket surface is soft, full and breathable, and can be directly cut into a blanket, and then the blanket is stitched by a stitching machine, and the blanket is qualified and packaged for warehousing.
