Abstract

การประดิษฐ์เกี่ยวกับสิ่งทอที่ยืดหดได้ในสองทิศทางสิ่งทอนี้ประกอบด้วยเส้นใยพอลิเอสเทอร์กับพอลิเอธิลีน เทอร์ฟะธาเลทหรือพอลิบิวทิลีน เทอร์ฟะธาเลทโดยเส้นใยคู่จะ มีไบรีฟริน์เจนซ์ เท่ากับ9x10-3ถึง195x10-3และมีการย่นสาม มิติสิ่งทอดังกล่าวมีการยีดหดทั้งในทางตามแนวยาวและตามแนว ขวาง The invention of this bidirectional stretch textile consists of polyester and polyethylene fibers. Terphthalate or polybutylene terphathalate by double fibers will have bi franchisor equals 9x10-3 to 195x10-3 and has three creases. Such textile dimensions are stretched both longitudinally and transversely.

Claims

1. A bi-directional stretch textile consisting of at least 30% of double-strand polyester fibers. The polyethylene double fiber was prepared by spinning the polyethylene pair. Lean Ether Phthalate (substance A), which is polymerized with structural units. Containing sulfonate metal guards In a ratio equal to 1.5 to 6.0% moles With polyethylene terephthalate or polybutylene Ether phthalate (substance B) in side by side method and drag product out line. Such a pair of fibers contains only bryophyta. With 90x10-3 to 195x10-3 and are wrinkled in three dimensions, so textiles Such rates will retract in both the longitudinal and direct directions. Along the transverse in the following channel (formula) where L1 is the length along The verticality of the sample of the specified length and the duct of 5 cm. When combat, the weight is 5 grams and L2 is the vertical length of the sample. This when the loaded weight is 240g when Such textiles are non-woven textiles. And 1500g when it is woven or knitted.

2. Method for preparing textiles which have rate of shrinkage in both directions. Along the azimuth and the transverse direction in the range as follows (formula) where Where L1 is the vertical distance of the sample of the given length. And 5 cm courage when taking 5 g of weight and L2 is the length in the line. Plummet of the sample when loaded by the same given weight With 240 grams when the fabric is 1500g non-woven When such a textile is woven or braided, it is characterized in the preparation of raw textiles consisting of double-strands of polyester with In the reef is 85x10-3 to 190x10-3 in small quantities. More than 30% by weight, produced by dual spinning of inositol Terphthalate (substance A) in which the copolymerization with the structural unit There are sulfonate metals. In a ratio equal to 1.5 to 6.0% mole with polyethylene terephthalate or polybutylene. Etrphthalate (substance B) in a side-to-side method, and the product is drawn and beamed to the raw textiles with upper infrared rays in a relaxation state. To create the dimensional wrinkling of these twisted fibers to produce a stretchable textile composed of bryifreengence double fibers. Equal to 90x10-34 to 195x10-3

3. Method according to claim 2, which prepares such textiles by using strands A pair of polyester threads that are mechanically crinkled until the number of shortening. With 8-13 / 2.54 cm.

4. Method according to claim 3, in which the number of shortening of the double fiber Increased to 30 to 50 / 2.54 cm by projecting the upper infrared beam.

5. Method according to claim 2, which raw textiles are fed into Thermal processing in the short cycle method

6. Method according to claim 5, the starting temperature of the black process Processed with heat not higher than 70 c.

7. Method according to claim 2, in which the aforementioned chisel contains fibers that are Low melting point of 5 to 35% by weight (7 claims, 2 faces, 0 pic).
