Abstract
Abstract A polyamide shaped articles, particularly of fibrous structures or films, comprising a polyamide containing at least one additive selected from the group consisting of dyes, pigments and additives and specified polyesters derived from an alkylene dicarboxylic acid and an alkylene glycol. A process for manufacturing such polyamide shaped articles comprises the steps of: compounding a molten polyamide with a liquid mixture comprising the above defined additive and the above defined polyester as a vehicle; and melt-shaping the resulting compound.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
81 words
A polyamide shaped article which comprises a polyamide containing at least one substance selected from the group consisting of dyes, pigments and additives and a polymer constituted by a main component having a recurring unit represented by the following formula (I): -OC(R₁COO) k (R₂O) ℓ - (I) wherein k is a positive integer, ℓ is 1 or 2, R₁ is an alkylene group, -C m H 2m - (m=2∼12), and R₂ is an alkylene group, -C n H 2n - (n=2∼4).
Claim 2
Dependent Claim
81 words
A polyamide shaped article which comprises a polyamide containing at least one substance selected from the group consisting of dyes, pigments and additives and a polymer constituted by a main component having a recurring unit represented by the following formula (I): -OC(R₁COO) k (R₂O) ℓ - (I) wherein k is a positive integer, ℓ is 1 or 2, R₁ is an alkylene group, -C m H 2m - (m=2∼12), and R₂ is an alkylene group, -C n H 2n - (n=2∼4).
Claim 3
Dependent Claim
13 words
An article as claimed in claim 1, which is of a fibrous structure.
Claim 4
Dependent Claim
103 words
A process for manufacturing a polyamide shaped article as claimed in claim 1, which process comprises compounding a polyamide in a molten state with a liquid mixture comprising at least one substance selected from dyes, pigments and additives and a polymer vehicle constituted by a main component having a recurring unit represented by the following formula (I): -OC(R₁COO) k (R₂O) ℓ - (I) wherein k is a positive integer, ℓ is 1 or 2, R₁ is an alkylene group, -C m H 2m - (m=2∼12), and R₂ is an alkylene group, C n H 2n - (n=2∼4), and then melt-shaping the resulting compound.
Claim 5
Dependent Claim
15 words
A process as claimed in claim 3, wherein aid shaped article is a fibrous structure.
