The GERS system was conceived with the aim of obtaining, during the spinning process a yarn having in its structure worsted elasticity with a volume/count ratio, look and characteristics of a high class woollen lambswool, after garment fulling or, if the sweater is only pressed, of a light worsted yarn.

With the GERS system one also obtains the transformation of a fixed acrylic into HB. All mélange and Vigoureux colours are obtained by means of dyeing fixed tops. During the GERS spinning, a percentage of fibres becomes HB. This transformation is determined by setting the drafting gauge at the desired level. The retraction is also adjustable according to the spinner’s requirements.

One can therefore declare that the GERS system allows one to obtain a worsted yarn which, with same weight, has a much higher volume per length unit compared to standard yarn presently available on the market.

-
1. Even covering in the look of the sweater owed to a greater
voluminization of the GERS yarn compared with a standard worsted
one, with same count, twist, fineness.
2. Proportionally less use of material.
3. Softer touch, even look, high resistance and elasticity.
4. Use of raw materials: 100% Merinos of various blends; no
contra-indication in the utilization of treated unshrinkable and/or
superwash wool.

SOME EXAMPLES OF YARNS COMPARED

(from left to right):

	A. 100% Extrafine worsted wool Nm 2/28, m 19,5.

	.
	B. GERS yarn 100% wool Nm 2/28 same characteristics as previous one: count, twist and fineness.
	.
	.
	C. GERS yarn 70% wool, 30% cashmere. Same count, twist and fineness as previous ones.
	.
	.
	D. woollen yarn same count as previous yarns.

1.Worsted or semi-worsted preparation. From finisher, spindle frame, cans for coarse counts.

2.The slivers which enter the GERS spinning machine are subjected to a draft field where the GERS device determines the final

reaction conditions of the mass of fibres of yarn produced by this process.

3.The transformation field is formed by four critical, subsequent zones where:

Zone A: determines the preparation of the mass of fibres proportionally to the various lengths of fibres which make up the mass in process.

Zone B: "creator" gives divarication angles to a series of fibres with respect to the longitudinal axe; the bigger the angle, the shorter the length.

Zone C: is the heart of the GERS system, critical point of the process; a predetermined percentage of fibre is aroused and held in a state of active tension which we shall call "temporary extension". This extension is adjusted according to the required voluminization of yarn which is to be obtained at the end of the process. This value of voluminization can then be changed according to the requirements of the user and the physical characteristics of the material employed.

Zone D: determines the condensation of a part of the fibres in process. The yarn thus produced contains a predetermined percentage of fibres in a state of over-extension with respect to their original state of rest. The GERS system maintains though, the memory of the position of these fibres, which on the yarn are intimately integrated, homogeneously to the entire mass of the other fibres not processed in Zone C, thanks to their difference in length with respect to the fibres activated under temporary tension.

4. After being spun, GERS yarn will present itself as a yarn with the characteristics predetermined by the user. It can be subsequently twisted to two or more ply, according to the normal requirements of a knitwear product.

5. After twisting and subsequent hanking, the GERS yarn is to be placed in condition to bring back the entire mass of fibres to their original condition, bringing back into memory the temporary extension of the percentage of fibres processed in Zone C, by means of a simple steaming of hanks at a temperature of 85/90°C for 8/10 minutes should the yarn already have undergone dyeing in tops, or by means of boiling water during dyeing on hanks of the actual yarn. Drying must occur by means of hot air, the classical system used, and not by means of microwaves or ultrasound.
