Abstract
Official abstract text for this publication.
A knit fabric suitable as a reinforcement for elastomeric articles comprises a plurality of reinforcement yarns wherein each course of the fabric comprises either a first or second yarn, the modulus of the first yarn being different from the modulus of the second yarn, and the courses comprising the first and second yarns are arranged in one of the following sequences, (a) alternating courses comprise first and second yarns respectively, (b) the courses form a repeat pattern of, in order, a course comprising a first yarn, two courses comprising a second yarn and a course comprising a first yarn or (c) the courses form a repeat pattern of, in order, a course comprising a second yarn, two courses comprising a first yarn and a course comprising a second yarn.
First claim
Opening claim text (preview).
What is claimed is: 1. A knit fabric comprising at least three courses of different reinforcement yarns wherein (a) each course of the fabric comprises either a first or second or third yarn, the yarn having a tenacity of at least 2.2 g/dtex, (b) no more than two successive courses of the fabric comprise the same yarn, and (c) the fabric is a reinforcing component of a tubular elastomeric article, a tire or a composite structure. 2. The fabric of claim 1 , wherein at least two of the different yarns comprise filaments of the same polymer. 3. The fabric of claim 1 , wherein at least two of the different yarns comprise filaments of different polymers. 4. The fabric of claim 1 , wherein a first yarn comprises filaments of m-aramid and a second yarn comprises filaments of p-aramid. 5. A hose comprising the knitted fabric of claim 1 . 6. A tire comprising the knitted fabric of claim 1 . 7. A fiber reinforced composite structure comprising the knitted fabric of claim 1 .
