Embodiment 1

[0071] The preparation method of the blended yarn of the polyamide 56 fiber of the present embodiment and cotton is as follows:

[0072] Take 30kg of polyamide 56 fiber, use 180g Yuanchuang Oil Agent J5326-H Nylon Staple Fine Denier Finishing Spinning Oil Agent (antistatic agent) and 1.8kg of soft water above 90°C to mix evenly, and then spray the solution evenly through a watering can Place it on the polyamide 56 fiber at 28°C, 65% R.H. for 2 hours.

[0073] The specification of the polyamide 56 fiber used is: the linear density is 1.67dtex, the length is 38mm; the breaking strength of the polyamide 56 fiber is 6.5cN / dtex.

[0074] After 24 hours of treatment, the moisture regain of polyamide 56 fiber reaches 6.14%, and the mass specific resistance reaches 1×10 6 (Ω·g·cm -3 ), has good spinnability, and then the polyamide 56 fiber is subjected to opening and cleaning, carding and a pre-combination process, and finally the fixed weight of the pre-combined fiber strip is 18.7...

Embodiment 2

[0079] The preparation method of the blended yarn of the polyamide 56 fiber of the present embodiment and cotton is as follows:

[0080] Take 25kg of polyamide 56 fiber, mix it with 1.8kg of soft water above 90℃ with 180g of Yuanchuang Oil Agent J5326-H Nylon Staple Fine Denier Yarn Spinning Oil Agent (antistatic agent) and mix evenly, then spray the solution evenly through the nozzle Place it on polyamide 56 fiber for 24 hours at 26°C and 67% R.H.

[0081] The specification of the polyamide 56 fiber used is: the linear density is 1.67dtex, the length is 38mm; the breaking strength of the polyamide 56 fiber is 6.0cN / dtex.

[0082] After 24h treatment, the moisture regain of polyamide 56 fiber reaches 6.10%, and the mass specific resistance reaches 1.2×10 6 (Ω·g·cm -3 ), has good spinnability, and then the polyamide 56 fiber is subjected to opening and cleaning, carding and a pre-combination process, and finally the pre-combined fiber strip has a fixed weight of 21.2g / 5m, and...

Embodiment 3

[0087]The preparation method of the blended yarn of the polyamide 56 fiber of the present embodiment and cotton is as follows:

[0088] Take 25kg of polyamide 56 fiber, use 180g of Yuanchuang oil agent J5326-H nylon short filament fine denier post-spinning oil agent (antistatic agent) and 1.8kg of soft water above 90°C to mix evenly, and then pass the watering can head to evenly mix the solution Spray on the polyamide 56 fiber and place it at 29°C, 68% R.H. for 24h.

[0089] The specification of the polyamide 56 fiber used is: the linear density is 1.67dtex, the length is 38mm; the breaking strength of the polyamide 56 fiber is 5.8cN / dtex.

[0090] After 24 hours of treatment, the moisture regain of polyamide 56 fiber reaches 5.80%, and the mass specific resistance reaches 1.3×10 6 (Ω·g·cm -3 ), has good spinnability, and then the polyamide 56 fiber is subjected to opening and cleaning, carding and a pre-combination process, and finally the weight of the pre-combination fibe...

Abstract

The invention provides a blended yarn of polyamide fiber and cotton as well as a preparation method and application of the blended yarn. The blended yarn comprises, by weight, 10-90 parts of polyamide56 fibers and 10-90 parts of cotton fibers, preferably, 20 to 50 parts by weight of polyamide 56 fiber and 50 to 80 parts by weight of cotton fiber, wherein the total weight of the polyamide 56 fibers and the cotton fibers accounts for 10-100 wt% of the total weight of the blended yarn, and/or the breaking strength of the polyamide 56 fiber is greater than 5.5 cN/dtex. Fabric prepared from the blended yarn can greatly improve the wear resistance and durability of the fabric while maintaining good moisture absorption, softness and comfort, and is suitable for the application field with high requirements for the wear resistance and comfort of the fabric.

Description

technical field [0001] The invention relates to spinning technology and belongs to the field of textile technology, in particular to a blended yarn of polyamide fiber and cotton and its preparation method and application. Background technique [0002] Polyamide fiber is one of the first synthetic fibers put into industrial production in the world, and its output ranks second among synthetic fibers. It is made of polyamide by melt spinning, and is widely used in clothing, household and industrial fields. It has low density, high breaking strength, large elongation, excellent resilience and fatigue resistance, while the bending modulus and relative bending stiffness are small, the fiber is relatively soft, and its hygroscopicity is second only to vinylon among synthetic fibers. It is better among synthetic fibers. [0003] Polyamide fibers can be divided into filaments and staple fibers. Staple fibers are mainly used in the production of blended yarns and fabrics. When blend...
