A copper ion-complexed poly gamma-glutamic acid (γ-PGA)/chitosan (CS)/cotton blended antibacterial knitted fabric and a preparation method includes chitosan that is crosslinked with poly gamma-glutamic acid, then a copper-ammonia complex ion solution is added to prepare a spinning solution. The spinning solution is wet spun and then stretched, washed with water, finished, washed with water, and dried to get copper ion-complexed poly gamma-glutamic acid/chitosan composite fibers. The blended antibacterial knitted fabric is then prepared by using cotton fiber yarns and the composite fibers. There is a very high coordination coefficient between carboxyl groups of gamma-PGA and amino groups of CS, so the structure is stable. Poly-gamma glutamic acid can be used as water-retaining agent and heavy metal ion adsorbent, which can increase the loading rate of copper ions.

Computer-implemented method for determining production values for producing a custom-tailored, in particular skin-tight, knitted garment (31) for a limb (3) of a person, comprising the steps of receiving a three-dimensional dataset (11) of the limb (3) acquired using a 3D scan device (21), receiving at least one height value describing the dimension of a knitting row (9) in the lengthwise direction of the limb (3) and at least one total length value for at least one lengthwise section (4) of the garment (31) and determining a number of knitting rows (9) for the at least one section (4) of the garment (31) by dividing the total length value by the height value, evaluating the three-dimensional dataset (11) to derive a circumference information describing the circumference of the limb (3) along at least the length of the limb (3) covered by the at least one section (4), from the circumference information, determining a circumference value for each n-th knitting row (9) or each knitting row (9) except every n-th knitting row (9), wherein n is a natural number, in the at least one section (4), wherein the circumference values are used as and/or for deriving production values for the knitted garment (31).

The invention provides a system for performing dynamic production and knitting machine work management comprising a production demand management unit, an advanced scheduling management unit, a cloth pattern storage unit and a manufacturing execution unit. The production demand management unit receives at least one production demand data. The advanced scheduling management unit generates a production scheduling data according to working conditions of a plurality of knitting machines and the production demand data. The cloth pattern storage unit stores a plurality of knitting machine work setting data. The manufacturing execution unit controls each knitting machine to extract one of the plurality of knitting machine work setting data from the cloth pattern storage unit based on a production cloth pattern data. The knitting machine work setting data is forcibly deleted by the knitting machine when a knitting number meets a set value defined by the knitting number limiting data.

A fabric file release system for automatically calibrating a circular knitting machine includes a file release end which memorizes a plurality of fabric file and a controlled terminal in information connection with the file release end. Each of the plurality of fabric file comprises a plurality of knitting machine working marks and a plurality of setting parameter values respectively corresponding to one of the knitting machine working marks. The controlled terminal comprises a setting file of knitting machine working including the plurality of knitting machine working marks and a plurality of working parameter values respectively corresponding to one of the knitting machine working marks. The controlled terminal receives one of the fabric file and maps the setting parameter values corresponding to each of the knitting machine working marks to the working parameter values corresponding to each of the knitting machine working marks in the setting file of knitting machine working.

The disclosure discloses a control method of pattern loading for a high speed double needle bar warp knitting machine, and belongs to the technical field of warp knitting equipment. Through disposing two or more than two high speed FIFO pattern data cache regions on a shog controller, a data read-write conversion function of each cache region continuously and automatically is respectively realized. According to a current position of each guide bar, a target position of current shogging of an original pattern and a starting course position of a novel pattern, a control system of the double needle bar warp knitting machine automatically calculates a shogging displacement required by each guide bar in a pattern loading process, and sends out instruction information to a shog driving execution unit corresponding to each guide bar. In a respective underlapping interval allowed of each guide bar, the corresponding guide bar is respectively driven by the shog driving execution unit to respectively and precisely move to the starting course position of the novel pattern to complete the electronic shogging pattern loading. Needle collision caused by guide bar shogging during pattern loading is avoided. Pattern loading steps of the double needle bar warp knitting machine are simplified; the work intensity is reduced; and the work reliability is improved.

Computer based systems and methods for designing and manufacturing consumer products, including knit footwear uppers, and the like. The system provides digital controls for the customization of knitted components, including complex multi-structured knitted components. The system simulates deformations of knit structures and allows the user to control and visualize compensations in the structure(s) of the knitted component to better match between an intended knit design and the actual physical knitted component outcome. They system may manufacture/fabricate a knitted component based on the predicted/estimated deformation behavior of the knit.

Custom-fit versions of knitted articles are produced according to digital representations of objects for which the articles are to be manufactured. The digital representations, optionally augmented by surface fitting algorithms, allow for accurate scaling of pattern-specified stitch counts for pattern elements representing the article taking into account wales and courses densities for the material(s) from which the article is to be made. Displayed dimensionally-accurate representations of the custom-fit articles allow for user-specified style and fit preferences to be made and a final digital pattern of the article to be produced. Machine instructions representing pattern pieces to be knitted are automatically produced from the final digital pattern of the article for a target computerized knitting machine and the custom-fit article then manufactured according to the machine instructions.

Apparel patterns may be generated as a function of custom apparel information provided by a user, such as one or more measurements, colors, etc., such that the user can have apparel custom-knitted to their particular size and shape without having to acquiesce the high expense and long wait times typically associated with custom-fit clothing. After a custom apparel pattern is generated, a custom-knitted article can be manufactured based on the pattern by transmitting appropriate information to a knitting machine. Data produced while generating custom apparel patterns can be stored and used to optimize and improve the manufacturing of customized knitwear for subsequent users. Further, such data can be shared with third parties such that manufacturers or others can utilize one or more beneficial aspects of the present disclosure without having to implement all of the functionality that would otherwise be required to obtain such benefits.
