preparation example Construction

[0039] Wherein, the preparation method of modified thickener comprises the steps:

[0040] (1) Stir and dissolve sodium alginate and hydrogen peroxide in water to obtain sodium alginate solution; then add hydroxypropyl starch and α-amylase at the same time, the mass ratio of sodium alginate, hydrogen peroxide and starch is 20~30:0.3~ 0.5: 10-15, add α-amylase at 400-600u / g starch; then stir and react at 35-46°C for 8-18 hours, then add sodium carbonate and gluconolactone, the amount of sodium carbonate added is the above The weight of the mixed solution is 0.2-1%, the mass ratio of sodium carbonate to gluconolactone is 0.8-1:1, and after stirring and reacting, a sodium alginate / starch composite solution is obtained;

[0041] (2) Adjust the pH of the sodium alginate solution obtained in step (1) to 3.7-4.5, and add formaldehyde, N, N, N-methylenebisacrylamide, acrylic acid, cyclohexyl isonitrile and dipropylene phthalate are stirred, and then the pH is adjusted to 5-6 with amm...

Embodiment 1

[0044] A method for producing a raschel blanket engraved with large circular grids, comprising the following steps:

[0045] (a) Use ultra-bright polyester ultra-fine fiber 167dtex / 228F ultra-fine denier polyester low-stretch yarn and 167dtex / 84F polyester full-drawn super-bright yarn to carry out warp knitting at intervals, use CAD system to control the warp knitting machine, and move in opposite directions The wool yarn bar of the warp knitting machine is cut after obtaining the gray cloth, and the hair height is 10mm;

Abstract

The invention relates to the field of production methods of blankets, and discloses a production method of a large-circulation grid carved raschel blanket. The production method of the large-circulation grid carved raschel blanket comprises the following steps of selecting two super bright polyester fibers for interval arrangement and warp knitting, controlling a warp knitting machine by using a CAD (Computer Aided Design) system, moving wool yarn guide bars of the warp knitting machine in different directions, and cutting after obtaining grey cloth; dyeing the grey cloth in a pad dyeing mode, wherein dye liquor comprises disperse dye and a thickening agent; then conducting steaming color fixing treatment; and conducting post-treatment: carrying out water washing and softening treatment by using a softening agent, then dehydrating, and then sequentially carrying out tentering setting, high-comb carding, two-time ironing and shearing and two-time lustre finishing treatment to finally obtain the large-circulation grid carved raschel blanket. According to the production method of the large-circulation grid carved raschel blanket provided by the invention, by utilizing different light reflection characteristics of the two kinds of bright filaments, the product has different luster and is rich in stereoscopic impression; and a square carved pattern is clear, the texture is vivid, the abstraction sense is strong, and the blanket is soft and good in use comfort.

Description

technical field [0001] The invention relates to the field of production methods of blankets, in particular to a production method of a large-circulation grid engraved Raschel blanket. Background technique [0002] Carpet has soft texture and comfortable foot feeling. It is especially suitable for the floor decoration of bedrooms, living rooms, study rooms and halls in homes and hotels. After decoration, it can also reflect noble, gorgeous, beautiful and elegant styles. . Raschel blankets are knitted on raschel machines and made by splitting, printing, finishing and sewing hemming. Raschel blankets have the characteristics of soft touch, full tufts, strong nap feeling, and pleasing color patterns. Compared with other blankets, it has outstanding advantages: very comfortable and soft hand feeling, fine fibers, no lint, warm and breathable, digitally dyed, bright colors without fading, unique thermal performance, and belongs to one of the main bedding products. [0003] The ...
