Patent application number ZL201410127728.0 Patent application number ZL2014140180.3 Patent application number ZL2014/kloc-. 402465438 There are not only rich and loose fertile soil, rare non-waterlogged paddy fields and slightly saline-alkali geology, but also warm all the year round, with an average annual temperature of 65438 05.8℃ and plenty of sunshine, which attracts humid subtropical monsoon, thus cultivating the best deciduous tree of Moraceae, Mulberry, and taking root from generation to generation.
Huang Qian has a unique vision. It has successively located a huge sericulture base of nearly 200,000 mu in Tongxiang, Zhejiang and Mengshan, Guangxi, where the Golden Corridor is located. He fully developed, cultivated and built them, and made use of geographical advantages to cultivate the innate advantages for choosing first-class double-palace cocoon quilts, becoming the only boutique enterprise in the silk quilt enterprise that built its own silkworm egg base.
Tongxiang and Mengshan not only have superior natural environment, but also have a long tradition of sericulture, which laid a beautiful foundation for the success of Huang Qian. In order to improve the quality and quantity of silk in sericulture base, Huang Qian has given various technical support to the base. 1. Introduce, develop and popularize advanced technologies.
(1) Introduce excellent mulberry varieties. The promotion rate of improved silkworm varieties in silkworm base reached 100%, which ensured the supply of high-quality silkworm and greatly improved the benefit of silkworm rearing.
(2) Introduce advanced sericulture technologies and models for the sericulture base, including high-yield and high-quality sericulture construction technology, standardized sericulture technology, green comprehensive control technology of silkworm diseases, and silkworm insertion technology (the annual sericulture is increased from 6 batches to 12 batches).
2, technical training for sericulture farmers in the base. With demonstration households as the main body, carry out technical training for base cadres and farmers.
3. Establish sericulture technical service department. In Mengshan, Guangxi, and Tongxiang, Zhejiang, long-term sericulture technical consulting service departments have been established to promote sericulture technology for a long time and serve the farmers in the base. From raw materials to quilts, from appearance to stitching, from silk to kits, Huang Qian has five strict tests, and no mistakes are allowed. Only selected mulberry cocoons that meet the three-dimensional standards of perfect cocoon shape, cocoon color and cocoon quality and high-quality selected double-palace mulberry cocoons are eligible to be selected as raw materials for Huang Qian silk quilt.
1. Select high-quality cocoons.
Inferior mulberry cocoon
There are more than three kinds of defects on the surface of cocoon layer, such as serious marks, uneven thickness of cocoon layer, floating state, velvet shrinkage, soft hand feeling, abnormal color, not white, pupa rot, mildew and so on.
Ordinary mulberry cocoon: serious yellow spots, defects and light weight.
High-quality mulberry cocoon: cocoon shape, cocoon color, cocoon layer thickness and shrinkage are normal, without defects.
Selected mulberry cocoons: cocoon shape and size are consistent, cocoon color and purity are consistent, and cocoon layer thickness is consistent.
High quality selection of Gong Shuangsang cocoon
Cocoons are similar to -H type: the circumference is more than 8cm and less than 9 cm; M type: girth greater than 8cm and less than10 cm; ; L-shape: cocoons with a circumference of more than 8cm and less than 1 1cm are all of the same color-there is no difference in color, and cocoons with color level 5 (the highest level) are of excellent quality-the cocoon layer is uniform in thickness, shrinking and wrinkling, and the touch is warm and smooth.
Only the high-quality selected silkworm cocoons that meet the perfect three-dimensional requirements can be selected as the raw materials of Huang Qian silk quilt.
Strictly control the quality of silk
(1) moisture regain: keep it at 7%~ 12% to avoid being too wet or too dry. All unqualified products should be reworked.
(2) Oil content: constant at 0.8%~ 1.5%, to avoid yellowing and hardening of silk due to excessive oil content, or rough and non-sticky silk surface due to broken film. Unqualified products should be scrapped.
(3) Compression rebound: according to different grades, the standard index of matching is verified: higher than the superior product-compression ratio >; 50%, rebound rate > 95%; Excellent products-compression ratio > 45%, rebound rate >; 95%; First-class products-compression ratio > 40%, rebound rate >; 90%。 All qualified products except the above are regarded as unqualified products by Huang Qian and are not used for production.
(4) Grade of chromatic aberration: Grade 5 (almost indistinct) is higher than Grade 4 (chromatic aberration can only be found if you look closely), and Grade 3 (obvious chromatic aberration) is 1 grade.
All qualified products except the above are regarded as unqualified products by Huang Qian and are not used for production.
Stage inspection of tire outer tire products
Items submitted for inspection according to national standards: fabric composition, formaldehyde content, PH value, color fastness, change rate of washing size, decomposable aromatic amine and odor. Huang Qian internal self-inspection items: detect fabric damage, stains, color difference grade, sewing thread, zipper, durability labels of accessories, etc. , detect the details of needle jumping, floating needle, missing needle burr and finished product details.
Appearance: no damage, no dirt, wireless head thickness: uniform thickness, the difference rate is not more than 8%; The four corners are square, and the difference rate is not less than 40%. Edge: the four sides are full and the positioning is firm and not loose; The zipper is complete, and the sewing needle of the tire cover is not less than 10 needle /3cm. Finished product outbound inspection.
Verify that the product number is correct, the outer packaging is not damaged, and the total weight including packaging is consistent with the set weight.
