Cones


For a conical package shape

Tubes


For cops are the most flexible base for a wide range of package shapes (e.g.: cylindrical - no taper / biconical - double taper / single taper / bottle shape), depending on the winding unit (type of winding)

King spools


For sewing threads / final make-up

Tubes sewing thread


For cop for sewing threads with 1.5" - 2" traverse length

Tubes sewing thread


For cop for sewing threads with 2" - 6" traverse length

Cones sewing thread


For a conical package shape with 3" - 4" traverse length

Cones sewing thread


For a conical package shape with  6" traverse length

tuck with the yarn tail in the thread

Sewing Thread


Sewing threads yarns are especially made to pass rapidly through a sewing machine. It is a fine cord of a fibrous material, made of two or more filaments twisted together. The yarn has to form efficient stitches without breaking or becoming distorted.


Spun yarn


Textile yarn spun and twisted from staple length fiber, either natural or synthetic.


Filament Yarn


Synthetic yarn composed of one or more filaments that run the whole

length of the yarn. Yarns of one filament are referred to as mono-filament; yarns of several filaments as multi-filament.


Cotton


Natural fibre from the cotton plant which is spun into fine yarn.


Polyester


Synthetic fiber made from a thermoplastic polymer that contain the ester functional group in their main chain. Most commonly refers to a type called polyethylene terephthalate (PET) or polyethylene succinate (PES) with a melting point from 103 – 106°C


Polypropylene (PP)


Polypropylene is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes. An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.


Aramid


Aramid is the short term for aromatic polyamide. They are fibres, in which the chain molecules are highly oriented along the fibre axis, so the strength of the chemical bond can be exploited. The fibre is heat-resistant and of great strength. Aramid is used in materials for bulletproof vests and radial tires.


Viscose


Viscose, formerly known as viscose rayon, is made by treating cellulose with caustic alkali solution and carbon disulphide. It is a soft fibre commonly used in dresses, linings, shirts, shorts, coats, jackets, and other outerwear.


Technical Yarns


The yarns are used for technical textile products, manufactured for non-aesthetic purposes, where function (rigidity, strength, dimension stability, design flexibility and economic viability) is the primary criterion.

The function of winder

Winding machine is a special equipment in textile industry. Winding, as the last process of spinning and the first process of weaving, plays the role of "bridge" connecting the preceding and the following, so it occupies an important position in the textile field.

Main tasks of winder:

1. Change the package and increase the volume of yarn: Connect the less capacity yarns (or hanks) through winding, and make the bigger package. The capacity of one package is equal to more than twenty tubes. The bobbin can be used for warping, twisting, weft winding, dyeing, weft on shuttleless looms and knitting yarns. If these processes use the yarn directly, it will cause too much stop time, affect the improvement of production efficiency, but also affect the improvement of product quality. Therefore, increasing the volume of package is a necessary condition to improve the productivity and quality of the later process.

2. Eliminate yarn defects and improve yarn quality: There are some defects and impurities in the yarns produced by cotton spinning mills, such as slubs, details, double yarns, weak twist yarns, neps and so on. When winding, yarn clearing device is used to check the yarn, remove the defects and impurities that affect the quality of the fabric, improve the uniformity and finish of the yarn, so as to reduce yarn breakage in the later process and improve the appearance quality of the fabric. It is most reasonable that defects and impurities in yarn are removed in winding process, because the work of each cylinder is carried out independently in winding process, and other cylinders can continue to work unaffected in dealing with broken ends in one cylinder.

Process requirements for winding:

1. Proper winding tension does not damage the original physical and mechanical properties of the yarn.

2. The drum has large volume and good shape, so it is easy to unwind.

3. Yarn joints are small and firm, forming knotless yarns as far as possible.

4. The tube used for warping should be fixed length, and the tube used for dyeing should be uniform in structure (even rolling).
