Technical Field

The invention belongs to the field of garment processing, and particularly relates to a typesetting production method of underwear fabric.

Background

The tailoring rate of the underwear fabric is one of the main technical and economic indicators of clothing enterprises, and is directly related to the economic benefits of the enterprises. The cutting rate of the underwear fabric reflects the quantity of the underwear which can be produced by the fabric with certain quality. The tailoring yield is composed of two indexes, namely the fabric utilization rate and the tailoring yield when the sample plate is typeset. The fabric utilization rate is the proportion of the effective area of the sample plate to the area of the fabric, and can be obtained in the process of computer typesetting. The fabric quality required to be consumed by a certain number of underpants can be calculated according to the fabric utilization rate. The utilization rate of the fabric plays an important role in the tailoring yield, the cost of the product is directly determined, and the higher the utilization rate of the fabric is, the more products are produced. Thus. In the typesetting process, a user must take a way to obtain higher fabric utilization rate, which is more important for underwear enterprises with low unit price. With the delivery price already established, more products produced means higher profitability for the business. Because the tailoring rate is reflected by the tailoring rate on the basis of the utilization rate of the underwear fabric, the ideal underwear tailoring rate can be obtained only when the fabric utilization rate and the tailoring rate reach higher levels. Therefore, effective measures are needed to achieve the highest utilization rate of the underwear fabric and the stable cutting rate.

Detailed Description

The details of the present invention are described below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a typesetting production method of underwear fabric comprises the following steps:

s1, adjusting the width of the fabric,

the width specification of the fabric is increased moderately, and the width specification of the calculated width of the fabric is increased to 175cm and 153 cm; the width of the cylindrical fabric is adjusted up to 1cm, and the width of the open-width fabric is adjusted up to 2 cm;

s2, arranging templates with different sizes in a sleeving manner,

the size of the nested rows is matched and typeset, and the nested rows are combined with the single row, so that the actual unit consumption of the product is reduced;

s3, controlling the humidity of the production environment,

the relative humidity in the workshop is not lower than 40 percent, the spraying and the moistening are carried out when the standard can not be reached, the softening treatment is well carried out, the fabric keeps good elasticity and softness,

s4, laying cloth and cutting,

typesetting in a cutting workshop according to computer aided design software, and producing by adopting an automatic cloth paving machine and a cutting machine.

In practical application, S1, adjusting the fabric width, adding a detection process, strictly controlling the fabric width, returning or repairing the fabric which exceeds the tolerance requirement if the width deviation is found to be large, including between the same piece and the adjacent pieces, and trying to typeset again if the width integrally exceeds the tolerance, so that the influence on the cutting rate is reduced.

In practical application, the detection step also comprises fabric weight detection, a cutting workshop must master the change condition of the fabric weight, all used fabrics need to be comprehensively checked once every week, and the fabric weight is timely detected if necessary, so that the phenomenon that the fabric weight exceeds the standard when cutting is avoided; the gram weight of the fabric is controlled well according to the retraction and moisture absorption performance of different fabrics so as to ensure that the gram weight of the fabric is within an allowable tolerance range during cutting.

In practical application, in the step of laying and cutting in S4, after the cylindrical fabric is automatically laid, a steel belt cutting machine is used for cutting, the laid fabric needs to be cut off, and in order to avoid the shrinkage of the fabric in the cutting process, the fabric is additionally placed by 0.5 cm.

In practical applications, in the step of laying and cutting in S4, the finishing factory should not increase the temperature to speed up the car speed to increase the yield when final tentering setting or open width preshrinking or cylinder preshrinking setting; in the carrying process, the wild action of the fabric width should not be influenced.

The principle of the invention is as follows:

the underwear product is simpler, and the number of the garment pieces forming the underwear product is less, but the specifications are many. All have 6-8 specifications. When the computer typesetting is carried out, the fabric with one width specification is difficult to ensure that the fabric utilization rate of each specification product reaches the same level, and the height difference is large. The utilization rate of some fabrics is even lower than 60%, and a considerable part of fabrics become leftover materials, so that the unit consumption of products is increased, and the cost is increased. When typesetting, if the fabric utilization rate of two specification products is low, the single width specification is not suitable, and it is necessary to add one fabric width specification for selection during typesetting so as to solve the problem of too low fabric utilization rate. The fabric width is determined according to different yarn counts, different organizational structures and the characteristics of the fabric on the premise of meeting the longitudinal and transverse shrinkage rate of the fabric, and the width is not always completely consistent with the width required during typesetting. From the angle of improving the fabric utilization rate, the fabric utilization rate can be improved by about 5 to 00 percent by finely adjusting the width during typesetting.

The cutting rate consists of the fabric utilization rate and the cutting rate, and the fabric utilization rate determines the product list and is reflected by the cutting rate. The fabric utilization rate is closely related to the fabric width, the fabric utilization rate can be improved by selecting proper fabric width and adopting large and small template sleeve arrangements, so that the utilization rate of open-width fabric is maintained at 75-80%, and the utilization rate of cylindrical fabric is maintained at 80-85%. The fabric width is reasonably set in the production process, the difference is minimized, the section length loss is reduced, the fabric gram quality is controlled, and the planned addition rate is properly applied. So as to reduce the fluctuation of the cutting rate and stabilize the cutting rate at 100 to 101 percent.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the foregoing embodiments are merely illustrative of the technical spirit and features of the present invention, and the present invention is not limited thereto but may be implemented by those skilled in the art.
