Abstract (en)
To stretch out textiles, which have shrunk after washing, steam is sprayed across the fabric surface while it is tensed. The fabric is spread to give a flat surface while its longitudinal edges are gripped by a spreader. The fabric is heated, and steam is sprayed on to it, while the spreading action is increased. When the material is stretched sufficiently, the steam spray is stopped, and the fabric is cooled by an air flow. The coolant air flow is taken from the ambient atmosphere, blown across the fabric surface. The initial heating stage has a duration of 2-60 seconds. The spreading stage duration is 2-10 seconds. and the cooling stage lasts for 2-60 seconds. The steam is a dry steam, at a temp. of ≥ 140 degrees C. The steam is sprayed across the fabric surface by a blower, together with preheated air. An Independent claim is included for a stenter apparatus. with a fabric support surface (2) and a steam spray jet. Preferred Features: The steam jet has a blower, and a system to heat the blower air. The assembly also has a cold air blower system. The fabric edges are gripped by grip bars (B1,B2), operated by pneumatic or hydraulic pistons (5,6). The spreading action, to increase the fabric width, is through a pneumatic or hydraulic piston, with a stop switch to break off the action when the required width has been achieved. The working surface is covered by a fabric (4) resistant to heat and moisture, and preferably of NOMEX (RTM).
Abstract (fr)
L'invention concerne un procédé d'étirement de textiles rétrécis au nettoyage, par application d'une tension d'étirement sur la pièce de textile à étirer tandis que de la vapeur d'eau est injectée à travers la pièce à partir d'une surface plane soutenant cette pièce. L'invention concerne également un dispositif (1) destiné à ce procédé, comprenant des moyens de fixation (B1,B2) pour les extrémités d'une pièce de textile, des moyens pour augmenter la distance entre ces moyens de fixation (B1,B2), une surface de support (2) pour la pièce de textile à étirer et des moyens pour injecter de la vapeur d'eau à travers la pièce de textile en contact avec cette surface (2). <IMAGE>
