Description
Technical Field
The invention relates to the technical field of cotton spinning yarn production, in particular to a method for preventing chromatic aberration in a cotton spinning yarn production process.
Background
Cotton yarns are woven from cotton in many grades. The fiber coated on the seed of cotton plant of Malvaceae, also called cotton, short for cotton, is an important raw material in textile industry. The cotton fiber product has good moisture absorption and air permeability, is soft and warm, and has the advantages which are incomparable with other textile fibers in the aspects of comfort, sanitation and health of human bodies. Therefore, the consumption demand of cotton spinning yarn is increasing, and the mass production type enterprises are also increasing. However, since the quality of cotton spun yarn is very susceptible to the production process, ensuring stable color quality in the production process is the key point of the quality of cotton textile. At present, a plurality of production enterprises can not control color difference, which causes the quality of cotton spinning yarn to be reduced and the selling price to be low, thereby affecting the enterprise benefit.
Disclosure of Invention
The invention aims to provide a method for preventing color difference in the production process of cotton spinning yarns, which effectively ensures the color difference prevention in each process from the input of raw materials to the warehousing of products, thereby improving the quality of the cotton spinning yarns to the maximum extent.
In order to achieve the aim, the method for preventing color difference in the cotton spinning yarn production process comprises the following steps:
a, raw cotton inspection: the grade of the raw cotton is inspected manually or by an instrument, and the condition of serious mixed grade appears during manual inspection, and the raw cotton is required to be inspected again after goods return or batch-by-batch grading and batching; when in re-inspection, the raw cotton is inspected packet by adopting an HVI instrument according to the requirements of variety quality, and the raw cotton is put into use in batches according with the standard;
b, cotton blending and selecting: controlling the cotton blending components to be not less than 4 shipping marks, and considering the uniform matching of grade internal quality and color when the cotton blending components are extracted and adjusted, so that the cotton blending components are mutually compensated and balanced; shipping marks with large color difference need to be uniformly and symmetrically coded and distributed in multiple points; when the cotton is selected, the cotton with approximate color parameters is selected, cotton distribution personnel and the cotton are checked bag by bag, and the personnel often proofread and observe the cotton with uniform vision;
c, code disc checking: checking the code disc package by package, informing a cotton inspection room in time when finding that the grade or the color difference is found, completing the sorting work, packing the sorted packages into packages according to the original labels respectively, and binding the package cloth brushed with the original labels on the packages;
d, code disc arrangement: when the code disc is coded, the code disc is arranged according to a high-wrapping flat caulking, a low-wrapping loose height and a large area; the knitted cotton spinning yarn variety should be arranged with two disks, and a small amount of raw cotton, cotton waste and disk foot flower which are used together need to be caulked by a cylinder; a large amount of inspectors should supervise and urge inspection at the scene, and the vehicle can be driven after the signature is qualified; when double discs are adopted, a disc of cotton cannot be divided into double and half discs;
e, picking and placing cotton rolls with cotton cleaning: when the cotton rolls for blowing are placed and used, the cotton rolls are transversely paved and directly taken; knitting yarns and corduroy weft yarns, and cotton rolls which are cleared and wound up are independently stacked and used; raw materials, semi-finished products, cotton waste, cotton reuse and high-grade cotton blending or low-grade cotton blending are strictly forbidden to be used in a mixed mode;
f, the packaging process requirements of spun yarn, spooling, weft winding, twisting and cone yarn are as follows: the semi-finished products on the large flat car and the bad car can not be used in time on the car start machine on the same day or transferred to other machines; the variety modification needs to adjust the mark in time and clean various barrel feet; feeding slivers need to be matched uniformly, and two holes of one drawing frame need to be matched in a cross way; the management of the twisting part is enhanced, and yellow and white yarns with strong and weak twisting caused by slip, turning, improper tightness, oil shortage and spindle hook clamping flower of the spindle tape are prevented; when the bobbin is used, the different kinds of bobbins with different colors are used by adjacent machine tables;
g, warehousing of finished cheese: the finished cone yarn is produced on the same day, packed on the same day, put in storage on the same day, and the batch and box number are registered; the seeds can not be put in storage on the same day, and the production time is marked on the variety signboard;
h, stacking of finished products: finished products in a warehouse of the material place are stacked in different varieties, so that the finished products are distributed first and mixed batches are prevented from being distributed; and (4) recording the batch and the box number during delivery, so that the tracking is convenient.
Furthermore, the twisting process in the step f is firstly used, and the bobbin foot is processed in time when the spinning and pressing platform is changed to enhance the inspection.
Furthermore, in the step f, when the color difference of the same variety of the receiving batch in the bobbin winding process is large, the bobbin needs to be replaced.
Furthermore, in the step f, in the processes of spinning, winding, twisting and packaging of cone yarns, color difference is found in operation, and the color difference is removed in time and is processed separately.
The invention has the beneficial effects that: the invention inspects the grade of the raw cotton, if the mixed grade is serious, the return of goods is required or the package-by-package grading is divided into batches and then the inspection is carried out again, when the inspection is carried out again, according to the requirement of the quality of the variety, the HVI instrument can be adopted for package-by-package inspection, and the raw cotton is put into use after the batch, thereby effectively ensuring the quality of the raw cotton; when cotton is matched, fine matching is required, and large-area color difference caused by various factors inherent in raw cotton is prevented; when the cotton rolls for blowing are placed and used, the cotton rolls for blowing are horizontally paved and directly taken, and the mixed use of the mixed materials is strictly forbidden, so that the color difference is effectively prevented; if the color difference of the same type is large, the bobbin changing process needs to change the bobbin in time, and the bobbin changing process is connected with the subsequent process in time to explain the reason of the bobbin changing, so that the color difference caused by the large color difference of the joint is prevented.
The present invention is described in further detail below with reference to specific embodiments of examples, but the scope of the subject matter of the present invention is not to be construed as being limited to the examples, and all the technologies realized based on the above contents of the present invention are within the scope of the present invention.
